A number of initiatives have been taken in this regard, ranging from advanced early warning system of hazards, to community based disaster preparedness programme, disaster management in education, disaster communication network, disaster response force etc. While some progress has been made, there are still lot of grounds to be covered and a lot of gaps to be attended on an emergency basis. Disaster Management Act of 2005 has provided a legal and institutional framework at the national, provincial and local level to attend to these tasks in a comprehensive and systematic manner. Concerted attempts are now being made for better preparedness at every level. It is expected that all these initiatives would help us to better face the disasters in the waiting. I understand that all these and related issues are going to be discussed in National Conference on Future Challenges of Disaster Management in India being organized by the All India Foundation for Peace and Disaster Management at New Delhi on 7th July, 2007 I Wish the Conference all success.

India needs to be divided, educationally speaking, into zones where the different types of disasters are most likely to occur. The north is prone to earthquakes—the southern and eastern coasts to Tsunamis. Cyclones batter the east coast. Floods occur mainly in Bihar and the West Bengal, droughts occur in Rajasthan, Haryana and the Punjab. Landslides occur in mountainous areas and fire can occur anywhere. A new awareness of Disaster Management must now enter the psyche of the Indian people as self-help and preparedness will help people face future disasters in a safer way. With more education at school and university level, together with the communities everywhere at a local, national and international level, important knowledge of Disaster Management could bring India to the forefront of this subject in the world thereby helping other countries as well. The local communities in a specified danger area throughout India can play an important role in managing any disaster at any time. This book provides a broad range of critical and practical ideas and intensive information with the latest data regarding Disaster Management at local, regional, national and international levels. The importance of the Warning Systems, Remote Sensing, GPS (Global Positioning System) and the GIS (Geographical Information System) cannot be overemphasized as with highly trained people understanding and using this equipment, thousands of lives will be saved in the future.

Acknowledgements The disasters which have stretched our planet in the last ten years have been on such a monumental scale that the suffering from the aftermath has forced our minds to be mentally, physically, and emotionally prepared should another disaster occur. This book gives a message to the world community that the time to act has come now. The two words “Disaster Management” are now in the forefront of our minds and have outstripped “Environment” and “Ecology”, which have focused on the earth as it is. We are now dealing with new forces which are creating havoc on our planet due to different types of disasters in different forms. I am sure that this book will provide methods, approaches, and the latest application of Information Technology to reduce the challenges of disasters with the latest data. Firstly, I would like to acknowledge my late parents who gave me the opportunity to study. I would also like to thank Prof. Deepak Pental, Vice Chancellor, Delhi University, who always encouraged me to aim high. I am also grateful to Prof. Lal Wadhwa, James Cook University, Australia (my co-supervisor) for his valuable discussions regarding different environmental issues which affect both India and Australia. My sincere thanks also goes to Prof. M.S.S. Rawat, Dr. A.L. Ramanatahan, Dr. P.V. Khatri, Mr. Dhramvir Dahiya, and Mr. Sheel Kumar (who always encourages and stands by me). Last but not the least, I personally thank Prof. Joan Schreijaeg-Gilmour who helped me in arranging all the literature on Disaster Management for this conference.

Fire Disaster: Challenges, Opportunities and its Management A Case Study of Australia Joan Schreijaeg-Gilmour (Social Worker at International level) 23 Harwood Avenue, Mt. Kuring-Gai, NSW-2080, Sydney, Australia

INTRODUCTION Although fire has been, and continues to be, one of the most important factors influencing the structure and distribution of plant and animal communities in Australia, With about 20,000 species of vascular plants, a similar number of species of non-vascular plants, 5800 species of vertebrate animals, over 200,000 species of invertebrates and 250,000 species of fungi, the biodiversity of Australia (Nielsen & West 1994) is immense. Considering that fires may affect most of the land surface of Australia, there are many opportunities for fires to promote or adversely affect biodiversity. A number of principles relating fires to biodiversity are known but how fires affect all Australian species is far from well known. Even among vascular plants we have recorded only the crudest type of response to fires for a little overten per cent of the flora. Of the four elements known to man – air, earth, fire and water, it is fire itself that imbues him with the most fear. It is an element that has been with man since time immemorial and it is the same now as it was then – either an element of fuel for cooking and giving warmth or one of disaster and destruction. It is very important to observe and understand how the use and abuse of fire on this planet has helped shape man’s destiny in respect of where he lives, how he lives, how he builds his house and places of work and what steps he has had to take in order to control this fierce element of nature which in modern times often presents itself in a totally different environment from past times. We may ask ourselves, who were the first people to tame this element of fire for their own benefit and how did they create it? We need to give thought to these questions as in the answers lies the evolution of civilization on this planet.

History of Fire In pre-historic times there were not many people inhabiting this planet. Man was tribal and had to hunt for his food and the element of fire gave him two basic necessities of life – a fuel for cooking and a means of keeping him warm. It is food for thought to ask ourselves, “Where was the first fire on this planet? Was it caused by an overflow of lava from a volcanic eruption, igniting trees in its wake or was it caused by a bolt of lightning striking a tree, thus beginning the first forest fire? As the world’s population grew, man migrated very slowly to other countries and this migratory process is very closely linked to the cultural web that has been woven by the knowledge and use of fire in all countries throughout the world ever since. The findings of pottery from the ancient world, fired in the kilns of earlier times and their discovery (always a delight to the archaeologist), are further proof of how the fire element presents itself as a major contributor to art. Through being able to heat and preserve clay in the shape of water and oil urns, much history from ancient Greece, Italy, Egypt and many other Mediterranean countries, is preserved nowadays in all museums throughout the world for all to see. Even in painted art, fire has played a featured role. Primitive man lived in caves and fires were placed near the entrance but as man began to build houses, he was forced to have a fire inside his house and it is this very fact that developed another feature in an architecturally developing world – the chimney. No one knows who invented the chimney or in which country it was first built but we do know that the first chimneys were made of wood and covered with clay or mortar. Evidence of their existence has been found in Venice. These are reported to have collapsed in an earthquake in 1347. In England in the 18th century many fires would break out in houses because the clay or mortar lining the wooden chimneys, was not strong enough to withstand the heat, so a new law was brought into being on 7th April, 1719 that all chimneys were to be made of brick. Here again, we can see how the history of fire is interwoven with the evolution of architecture. Another very interesting aspect of fire in the fireplaces was the invention of a metal fire – cover called a “curfew”. This curfew had a wooden handle attached to a rounded metal plate which had holes in it and by placing it over the fire, the embers could be contained until the morning , thus making it easier to continue burning a fire the next day. In order to regulate this activity within the community, drums were beaten in some towns and villages and bells were rung in others and all people had to use their curfews at that time to cover their fires. It actually became law in 1068 in England during the reign of William the Conqueror that when the bells rang at 7 pm., all curfews were to be placed over the fires. People were also required at this time to put out their oil lamps used for lighting. This stopped people from wandering the streets at night. The word “curfew” comes from the French word “cuevrefeu” – covered fire, le feu

meaning “fire” and it has worked its way into the English language meaning “a regulation requiring people to remain indoors between specified hours at night.” Here we have the history of fire touching our language. Fire has stamped its mark on history when we remember that Rome burned to the ground and was destroyed in 64 BC in the time of Nero and the Great Fire of London on the 2nd September, 1666 raised it to the ground, thereby ridding the city of vermin and disease. A folk song developed from this fire called “London’s Burning”, so in music too we have some history of fire. Types of Fire 1. Bushfires or forest fires. 2. Chemical fires. 3. Electrical fires. In mediaeval times the old alchemists thought fire to be the primary agent of change and in Physics, fire corresponds to energy. In our present civilization we have three forms of fire: 1. In Australia many bushfires have been caused by a natural phenomenon such as a blitz of lightning or the rays from the sun shining through a piece of glass in the bush. Man made bushfires have been caused by the careless throwing of cigarette butts from car windows or people have camped and failed to put out their fire. The fires in buildings or in the bush which have been deliberately lit by the arsonists are another cause of bushfires. Arsonists in Australia can sometimes face up to 20 years in gaol if caught lighting fires deliberately. 2. Chemical fires are mainly fires which ignite in manufacturing plants, factories and places where chemicals are used or by road accidents where the heavy transport vehicles themselves are involved in a collision. 3. A third type of fire is caused by electrical faults from faulty wiring in homes, combined with overheated appliances. This type of fire goes too for restaurants, theatres, places of entertainment, shops, offices, factories, schools and hospitals. Australia is often described as the land of flood and fire. The Australian aborigines who have lived in the country for thousands of years before the white man came, were masters of fire. They were a nomadic race of people who knew when and where to burn the bush and when to move on to set up their camp somewhere else. They also knew which wood to choose in order to rub two sticks together for making a fire for cooking or a fire for keeping themselves warm. The burning of the bush in Australia is essential to its regeneration and it does regenerate very quickly after a major fire, but whereas the aborigines knew the climate and seasons so well because they lived close to nature, the bushfires in earlier days did not present the hazard that they do today.

No one knows who invented the chimney or in which country it was first The fires in buildings or in the bush which have been deliberately lit by the built but we do know that the first chimneys were made of wood and covered arsonists are another cause of bushfires. Arsonists in Australia can sometimes with clay or mortar. Evidence of their existence has been found in Venice. face up to 20 years in gaol if caught lighting fires deliberately. These are reported to have collapsed in an earthquake in 1347. 2. Chemical fires are mainly fires thwhich ignite in manufacturing plants, factories In England in the 18 century many fires would break out in houses and places where chemicals are used or by road accidents where the heavy because the clay or mortar lining the wooden chimneys, was not strong enough transport vehicles themselves are involved in a collision. to withstand the heat, so a new law was brought into being on 7th April, 1719 3. A third type of fire is caused by electrical faults from faulty wiring in homes, that all chimneys were to be made of brick. Here again, we can see how the combined with overheated appliances. This type of fire goes too for restaurants, history of fire is interwoven with the evolution of architecture. Another very theatres, places of entertainment, shops, offices, factories, schools and hospitals. interesting aspect of fire in the fireplaces was the invention of a metal fire – Australia is often described as the land of flood and fire. The Australian cover called a “curfew”. This curfew had a wooden handle attached to a rounded aborigines who have lived in the country for thousands of years before the metal plate which had holes in it and by placing it over the fire, the embers white man came, were masters of fire. They were a nomadic race of people could be contained until the morning , thus making it easier to continue burning who knew when and where to burn the bush and when to move on to set up a fire the next day. In order to regulate this activity within the community, their camp somewhere else. They also knew which wood to choose in order to drums were beaten in some towns and villages and bells were rung in others rub two sticks together for making a fire for cooking or a fire for keeping and all people had to use their curfews at that time to cover their fires. It themselves warm. actually became law in 1068 in England during the reign of William the Conqueror that when the bells rang at 7 pm., all curfews were to be placed The burning of the bush in Australia is essential to its regeneration and it over the fires. People were also required at this time to put out their oil lamps does regenerate very quickly after a major fire, but whereas the aborigines used for lighting. This stopped people from wandering the streets at night. The knew the climate and seasons so well because they lived close to nature, the word “curfew” comes from the French word “cuevrefeu” – covered fire, le feu bushfires in earlier days did not present the hazard that they do today.

meaning “fire” and it has worked its way into the English language meaning “a regulation requiring people to remain indoors between specified hours at night.” Here we have the history of fire touching our language. Fire has stamped its mark on history when we remember that Rome burned to the ground and was destroyed in 64 BC in the time of Nero and the Great Fire of London on the 2nd September, 1666 raised it to the ground, thereby ridding the city of vermin and disease. A folk song developed from this fire called “London’s Burning”, so in music too we have some history of fire. Types of Fire 1. Bushfires or forest fires. 2. Chemical fires. 3. Electrical fires. In mediaeval times the old alchemists thought fire to be the primary agent of change and in Physics, fire corresponds to energy. In our present civilization we have three forms of fire: 1. In Australia many bushfires have been caused by a natural phenomenon such as a blitz of lightning or the rays from the sun shining through a piece of glass in the bush. Man made bushfires have been caused by the careless throwing of cigarette butts from car windows or people have camped and failed to put out their fire. The fires in buildings or in the bush which have been deliberately lit by the arsonists are another cause of bushfires. Arsonists in Australia can sometimes face up to 20 years in gaol if caught lighting fires deliberately. 2. Chemical fires are mainly fires which ignite in manufacturing plants, factories and places where chemicals are used or by road accidents where the heavy transport vehicles themselves are involved in a collision. 3. A third type of fire is caused by electrical faults from faulty wiring in homes, combined with overheated appliances. This type of fire goes too for restaurants, theatres, places of entertainment, shops, offices, factories, schools and hospitals. Australia is often described as the land of flood and fire. The Australian aborigines who have lived in the country for thousands of years before the white man came, were masters of fire. They were a nomadic race of people who knew when and where to burn the bush and when to move on to set up their camp somewhere else. They also knew which wood to choose in order to rub two sticks together for making a fire for cooking or a fire for keeping themselves warm. The burning of the bush in Australia is essential to its regeneration and it does regenerate very quickly after a major fire, but whereas the aborigines knew the climate and seasons so well because they lived close to nature, the bushfires in earlier days did not present the hazard that they do today.

This has forced the Australian government to find greater solutions to fire fighting and investing in the most modern equipment. Many so-called civilized white people today have a lifestyle which is far removed from nature. Some can go for months without having a handful of soil in their hands, and many have wended their way into Politics to form the Green Party and this is where many fire problems, which we face today in Australia, start. Years ago, before we had our present rules and regulations for the “Conservation for the Environment,” we had what are called “fire breaks”in the bush and these were sections of bush 10 to 15 metres wide, where the bush was cleared in order to prevent a fire hopping from one section to another. Many of these fire breaks no longer exist with the result that we have “fire storms” now and we need special helicopters to water bomb the bush in inaccessible places. The bushfires that we now have pose an enormous threat at times to people’s lives, homes and of course, the wildlife. Many animals like the Australian Koala Bear and Wombat are slow to move but once they smell the fire coming, they can have time to escape. Some, unfortunately, do get burnt to death. It is very important in Australia that “back burning” is done at the proper time. This is a term used to describe the burning of all the loose twigs and leaves on the ground at the end of winter in August leading into spring in September. That is the time of year scheduled for my area at Mt. Kuring-Gai which is the highest part of Sydney and approximately 40 kms from the city. A fire from the bush in Australia can begin very quickly and sometimes it takes just the heat generated through a broken piece of glass to start a major fire. The forces of wind change can soon have a fire completely out of control. Within 15 minutes in Feb, 2007, a fire broke out north of Sydney. The fire was raging in the bush nearby and very soon the big helicopters were water bombing the bush and this saved all of the nearby homes. All main highway roads were closed and train services suspended for many hours. The below diagram shows the fire behaviour. Role of the Australian Government in Managing Fire The fire challenges for the Government of Australia have been enormous over the last twenty five years. Each state – New South Wales, Victoria, Tasmania, South Australia, Western Australia, Northern Territory and Queensland have each suffered enormous damage and deprivation because of the loss of human life, property, crops, sheep, cattle and other animals. In Australia a great fire spread out of control in Victoria in February 1983 right across to Adelaide, the Capital of South Australia. It was a real killer as 68 people died. The devastating effect and the enormity of the damage done by a fire storm in Australia cannot be put into words as its aftermath remains in the hearts of the people emotionally, financially and socially for years to come.

What is peculiar to the Australian Bush is the fact that almost 100% of the trees are many species of Eucalypts, which of course, contain Eucalyptus oil. This oil is extracted and used in many different ways medicinally and that is the positive side of it. On the negative side, it acts as an accelerant in a bushfire. The worst hazard facing any large bushfire is wind change and another hazard facing our landscape is the actual outbreak of a fire in a remote area of the bush. Watch towers are placed at strategic places throughout the bush and of course in this day and age, Remote Sensing and GIS would also be used. Because of a lot of “non clearing” and back burning in the bush, our bushfires now get very quickly out of control and they develop into fire storms. As the flames ascend the trees, the oil in the eucalyptus trees flares up and the fire is transmitted very quickly from tree to tree. Because of the enormity and severity of these storms, the Australian Government has been forced to acquire many large and specially fitted out Helicopters from America which are used for water bombing. They cost millions of Dollars. This has been money well spent

as it has given more peace of mind to many citizens. When fires break out in the Sydney. Metropolitan Area in summer, these Helicopters sometimes almost drain people’s swimming pools, as getting water quickly is the number one priority. Golf courses with their water hazards are another source of obtaining water quickly – much to the annoyance of golfers. The problems which fire has caused in Australia has forced the Government to re-think its policies on fire prevention, fire control and educating the general public in all aspects of safety relating to fire. In the workplace it is compulsory for all workers on building sites to wear safety helmets and steel capped shoes. When welding in addition to these two items, the workers must wear eye goggles, and gloves up to their elbows. This comes under the OHS Law which stands for Occupation, Health and Safety. Any employer found allowing a worker to operate not using proper safety equipment can have his licence to run a business immediately cancelled and a heavy fine imposed. Every truck on the road has to be equipped with a fire extinguisher to put out a possible engine fire and sometimes the truck drivers can come to the assistance of another motorist who may have a fire in his or her engine. How Australia Can Help India Considering how huge a country India is, with varied geographical features ranging from miles of coastline to the highest mountains in the world, natural disasters are understandably frequent at some part or another. India has had more than a fair share of earthquakes, cyclones, drought, landslides and floods. Some of the major disasters in the past few years are the December 2004 tsunami that hit the Indian Ocean, leaving more than a 300,000 people dead, the 2001 Gujarat earthquake, and the 1999 Orissa cyclone. Each of these disasters, and the many others that have struck the country, leave thousands of deaths in its wake, and due to their unexpected nature, put great pressure on government and civil society relief efforts. The main areas that require intervention in disaster mitigation are earthquakes,Fires, floods, cyclones and landslides. For earthquakes, building laws and by-laws, retrofitting and training in earthquake engineering and architecture have already been envisaged. Coastal plantation belts, shelters and preemptive warning systems can minimize the damage from cyclones to a great extent. Numerous flood control measures are already in operation to prevent the kind of floods that wreak havoc in states like West Bengal, Assam and Bihar. Geological surveys, hazard zonation and monitoring go a long way towards reducing the risk from landslides. Above all, what is required is awareness among all citizens of the possible dangers from various disasters, be they natural or human-made. With each disaster, along with the death and misery, there is also something to learn that equips us to deal better with the next one. Greater research needs to be conducted into the patterns of disaster occurrence and their outcomes,

and also possible further victimization during relief and rehabilitation. For many survivors, a disaster is only a long chain of events the outcome of which is not immediately apparent. It is only through the involvement with the local community, those who have been hit hardest by the disaster, that appropriate measures can be taken and networks set up for the survivors’ housing and livelihood needs. Finally, it is not only natural disasters that can wreak havoc on people’s lives. Human-made disasters, such as war and riots have the same effects. One of the first steps in relief and recovery following a disaster is to restore the livelihoods of the affected people. While aid in the form of food, clothing and shelter is often made readily available, little is done for disaster victims, especially those of the economically marginalized groups, who look ahead to a bleak future because of their sole means of earning being completely destroyed. In such situations, it is the condition of women that is especially the most precarious, especially if their husbands or fathers, who are often the sole earning members of the family, have been victims. In desperation, survivors often migrate to cities and other regions, adding to the migrant labour population. Survivors also run a great health risk in the form of epidemics after coming in contact with contaminated food, water and air in the wake of a large-scale disaster that has claimed a lot of lives. The way that the Australian Government handles fire disasters can be a role model for India. For every problem the challenge is always to be found in finding a solution. No doubt in India, forests fires can combust from the heat from the stones. Also, when villagers go into the forest to smoke, they too can be careless and accidentally start a fire. So in a way our problems are similar. Australia has a population of 20 million people which is the population of Delhi, and the majority of people live in the coastal areas. In my country, we have compulsory education up to the age of sixteen and because we have far fewer people and less manpower than India has to do the work, we are forced to use machinery to get a job done. This fact has forced our fire services to be highly mechanized.More and better education creates a better understanding of the word “awareness”. There are fire hazards in both countries. In India, fires can break out in the wheat harvesting season just from a spark from the silencer in a tractor. This is where the organization of fire control should be on hand before harvesting commences. Also in the villages, the people need to be educated and made aware of fire dangers in their homes and kitchens and how their animals can be better housed and protected against fire. Major fire hazards in India present tremendous challenge to the local Municipality and the people who live in the vicinity of the fire. Take for example, the major fire hazards in the Manali Himalayan forest area of Himachal Pradesh where the people store fodder for the animals over the winter months together with fuel. It is well recorded that Kothi which is a Tourist Destination a few kilometers north of Manali has had destructive fires in 1974, 1984 and 1995 when the whole village has been

burnt out each time. This is a true example of how the forces of nature create a fire disaster and man himself is faced with the challenge of putting it out. Everything boils down to education preparation, organization and infrastructure. With the enormous progress that India has made since the 1990s, I feel sure that some Indian Government officials would benefit greatly from a visit to Australia to experience first hand how we organize our entire fire service throughout the country. Because of the IT industry in India and other big business concerns, the workers both in India and Australia now find themselves in very tall, glass, air conditioned high rise buildings well beyond the reach of any fireman’s ladder. Again constant practice of escaping in case of a fire in these buildings needs to be carried out regularly because in such buildings, one is never to use the lifts. Is this being done in India? The best quality and best equipped fire engines in the world are made by Daimler Benz in Germany and it would be good for India to acquire one for each major city. Surely, with the coming of the Commonwealth Games in India in 2010, it will be a great opportunity to make this country the showcase of the world. CONCLUSION AND SUGGESTIONS The Australian Government has spent a tremendous amount of money on the infrastructure of fighting fires in Australia. Our fire services are one of the best services in the world. All our men are very highly skilled and trained in all aspects of the hazards connected with fire. The most modern equipment is used and the firemen respond within seconds when their services are required.We also have the Voluntary Fire Brigade made up from men who have done a day’s work in the office,come home,and then start fighting fires, often until midnight. Through government Laws and regulations all people working in hospitals, retirement villages, schools and shops are regularly trained in what to do in case of a fire. In this training for a hospital fire for example, a trainee was once told that in the event of a hospital fire one must first place one’s hand on a ward door. If it be too hot to touch for two seconds, one goes to the next ward. The horrified trainee had thoughts about the six patients in the ward, but the fireman training him raised the question “Do you want to be another victim?” The firemen themselves train the employees and teach them about the danger of faulty wiring in their own homes and what items should be left unplugged. There are also plenty of brochures issued to the general public from the local councils on how to prevent fires in your own home. One of the most dangerous places for fire danger in the home is found in the kitchen when people are taught the importance of switching off an electrical hot plate after cooking or turning off a gas jet when cooking is complete. This goes for restaurants too where another danger can loom, when fat gets overheated and ignites a combustible material nearby. Fire can spread very quickly in a restaurant kitchen

particularly if the building be old and the stairwell is nearby. It is compulsory by law for all places of work to be fitted out with emergency fire fighting cylinders for electrical or chemical fires and since September 2006, all private homes in New South Wales have to be fitted with smoke alarms. These are battery operated devices placed strategically in the homes to detect the first hint of smoke and many lives have been saved since their installation. Conversely, many people have been burnt to death in their homes because of a lack of smoke alarms. They die though from smoke inhalation before they are burnt to death. Does the Indian Government also enforce such laws? In Australia we have very highly skilled men, who work in conjunction with the firemen, police and insurance companies to established the cause of a fire and to prove if any accelerant like petrol has been used to start it. Naturally in Australia like every other country in the world, fires have been deliberately lit for insurance purposes, but nowadays with highly developed technical equipment used by the arson squad of our Police Force, most of these crimes are very quickly solved. With all of the Fire Disasters that have ever been in Australia, we have met the challenges which mother nature has presented to us with the full force of our manpower, intelligence, knowledge, bravery and above all from our management of fire because we know in advance that fire will always be with us and our organization is such that we are always prepared for every emergency, every type of fire at any place and at any time. Do come and visit us. With each disaster, along with the death and misery, there is also something to learn that equips us to deal better with the next one. Greater research needs to be conducted into the patterns of disaster occurrence and their outcomes, and also possible further victimization during relief and rehabilitation. For many survivors, a disaster is only a long chain of events the outcome of which is not immediately apparent. It is only through the involvement with the local community, those who have been hit hardest by the disaster, that appropriate measures can be taken and networks set up for the survivors’ housing and livelihood needs.

INTRODUCTION The history of the development of the present New Okhla Industrial Development Authority area can be traced as far back as 1972 when the U.P. Govt., taking note of the mounting pressure of speculative land dealings in this area, closely situated to Delhi having backward characteristics declared 50 villages of the erstwhile district of Bulandshahar as the “Yamuna-Hindon-Delhi Border Regulated Area”, under U.P. Regulations of Building Operations Act, 1958. The need for establishing an urban centre in close proximity to Delhi was felt, due to the following reasons: i) Decentralization of economic activities from the National Capital and thereby preventing the in-migration to Delhi and help in decongesting the Metropolis. ii) To stop speculative land dealings in the areas under influence of the Metropolis giving rise to an unplanned and haphazard growth in the region. iii) Provide an alternative site for the small and medium size industries functioning in the non-conforming areas in and around Delhi at a much lower price and at the same time at the doorstep of Delhi. iv) Provide a reasonably decent site for residential development within a manageable distance from Delhi due to the non-availability of land in Delhi at a reasonable price. On March 7, 1972, the Controlling Authority considered various aspects of the development of a Regulated Area, which then consisted of an area of about 120 sq. km. and a population of approximately-42000 persons. On April 17, 1976, the U.P. Govt. constituted an Industrial Development Authority for 37 villages of this area under Sec. 3 (1) of the U.P. Industrial Area Development Act, 1976 (U.P. Act NO.6 of 1976).

Connaught Place, the heart of Delhi, lies merely 15 km from the centre of the NOIDA city. It is located on the left bank of the river and is equidistant from Ghaziabad and Delhi. It was developed near Delhi, across the Yamuna river, in the 1970’s as a modern industrial city. There has been an extensive growth of population in Noida during the last two decades and the population is estimated to be about half a million. There is now a Greater Noida township being developed on the outskirts of Noida, to cater to the phenomenal influx of population into this region.

There has been an extensive growth of population in Noida during the last two decades and the population is estimated to be about half a million. There is now a Greater Noida township being developed on the outskirts of Noida, to cater to the phenomenal influx of population into this region. The township lies at an average elevation of 200m above Mean Sea Level and has a flat topography.

The New Okhla Industrial Area, an authority established under this Act, is not only responsible for the preparation and execution of a developmental plan for the Industrial Development Area but also for maintaining and providing amenities such as roads, water supply, street lighting, power supply, collection and disposal of sewage etc. The Authority has also been empowered to levy taxes with the previous approval of the State Govt. for this purpose. The Authority can also receive funds from different sources in various forms, such as loans, grants, debentures etc. for the execution of its development plans. The Authority has been further empowered to regulate the erection of buildings, the development of sites and to issue regulations/directions regarding buildings and developmental activities in order to ensure planned development. Thus, the Authority has the responsibility of the entire development taking place in the notified area. The development of the industrial sectors in the area adjoining the DelhiU.P. Border started in the year 1976 according to the Master Plan prepared by the Town and Country Planning Department, Govt. of U. P. By the end of the first financial year i.e. March, 1977, the physical infrastructure for the entire industrial area had already been laid. About 1,000 industrial sheds were constructed and a big number of the industrial plots sold to the prospective entrepreneurs. It is bounded by the Yamuna river and the city of Delhi in the west and the south west, National Highway 24 and the city of Ghaziabad in the north, river Hindon and Greater Noida Area in the east, and the confluence of the Yamuna and Hindon in the south. Connaught Place, the heart of Delhi, lies merely 15 km from the centre of the NOIDA city. It is located on the left bank of the river and is equidistant from Ghaziabad and Delhi. It was developed near Delhi, across the Yamuna river, in the 1970’s as a modern industrial city. There has been an extensive growth of population in Noida during the last two decades and the population is estimated to be about half a million. There is now a Greater Noida township being developed on the outskirts of Noida, to cater to the phenomenal influx of population into this region. The township lies at an average elevation of 200m above Mean Sea Level and has a flat topography.

are some of the characteristics of this Noida city which pose serious challenges related to meeting the demands for collective urban services, keeping a sound natural environment, and reducing physical, social and institutional vulnerabilities. This work will provide a base to analyse risk management and understand vulnerabilities of various types including natural, infrastructural etc. So, this is an attempt to outline a disaster management plan of the Noida city because it does not include each and every aspect of the environment, but it has taken into account only flood and seismic vulnerability and these two are the basic problems of Noida being a zone IV region on the Mercelli scale. The people who cannot meet even their daily necessities cannot be expected to take sufficient safeguards against natural disasters and combat various epidemics that usually follow such occurrences. The people’s proneness to disasters increases because, by the process of elimination, they are forced to live in low lying areas subjected to frequent flooding vulnerability as in Noida. This type of growth requires sophisticated mechanisms to carry out disaster preparedness and emergency operations. On the contrary, this city has limited access to the wherewithal for quickly evicting people from the site of disaster or shifting to alternative shelters and in the process, the affected people also get exposed to various climatic and environmental vagaries and thus suffer additionally due to the various reasons. The institutional framework for educating the poor and preventing them from inhabiting vulnerable areas is either absent or weak. Even if such an arrangement exists there is a general lack of will to act and as a result, substantially large proportions of the poor and deprived population live in disaster prone areas and suffer immensely every time the disaster strikes. Disaster Management and Land Use Policy Noida has been planned on the grid iron concept and employs state-of-the-art technology in Engineering, Urban Planning and Architecture. Significantly, it conceptualizes the needs of a fast developing city of the future. The Action Plan and approach compares well with international standards and is aimed at providing rapid momentum to the growth of the industrial sector both in the State of Uttar Pradesh and the Country Planning. NOIDA, after acquiring 385 acres of land, has acquired and developed over 5,888 hectares of land until now. During the current year, 3 residential sectors and 2 industrial sectors have been developed. In the decade ahead, 3,400 hectares of land will be acquired and developed, out of which 430 hectares have been earmarked for residential, 620 hectares for commercial, 650 hectares for industrial and 200 hectares for institutional purposes. Another 300 hectares of land have been earmarked for development of recreational purposes which will include Entertainment Park and a centre for musical and cultural activities. 125 hectares of land will be utilized for creation of road transport facilities including a bus terminal.

Disaster management is a more recent concept of linking environmental, economic and social use values. The concept of land-use change management screens the balance of these three values for land-use planning. Land-use management and policy decisions are almost always based on the analysis of the factors pertaining to each particular issue. When considering the sustainable development of land, land-use change management is an important phenomenon. The content of land-use change management can be described in terms of three value sets (ecological, social and market values) that must be brought into balance by land planning. It indicates that the whole area accommodated 11, 91263 people (0.72% of the state population) in the year 2001 as compared with 1991, when the total no of population was 8,77853(0.67% of the state population). Even ranking on the basis of the population density, the district has gone up in standard as it was on the 21st rank with the population density of 692 and now it is 15th on the rank with a population density 939. As a result of the close proximity to Delhi and a good surrounding environment, the demand for land is increasing. In the recent past, the land values in the area have increased at an alarming rate. This is partly due to present unplanned development and misuses of the land. As a consequence, valuable agricultural lands have been converted to urban uses without proper planning. Zonation Regulation and Disaster Management The Zonation regulations are key to urban flood disaster management in Noida (Gautam Budh Nagar). These regulations comprise a map depicting the various zones, plus related metadata. Most importantly, a zonation regulation indicates where certain uses of land, buildings and other structures (e. g. agricultural, residential, industrial, commercial, public) are permitted. Other important measures that can be incorporated into a zonation plan (these are not compulsory) include the following: • Target densities can be set for residential areas. This is important as recent experiences highlight the increased fatalities in high-density areas, especially when there are no open spaces available for evacuation purposes. • Maximum “plot coverages” can be set to guarantee some open space within a plot. A plot coverage of 60% in a plot of 400 m2, for example, would translate into a maximum240 m2 of roof area, leaving 120 m2 as open space. This is an important disaster mitigation tool as it can be used to force people to allow room for a garden where they can go in the event of an earthquake. In the case of single-family dwellings, minimum plot sizes can be set in terms of plot area as well as minimum width and width/length relationships. For example, current regulations allow a minimum width of 6 m and a maximum width/length relationship of one to seven. This tool could be used to avoid extremely long passages that could make evacuation to the roads difficult. In the case of Maximum building height, it is also an important aspect in earthquake mitigation.

Most importantly, a zonation regulation indicates where certain uses of land, buildings and other structures (e. g. agricultural, residential, industrial, commercial, public) are permitted. Other important measures that can be incorporated into a zonation plan (these are not compulsory) include the following: • Target densities can be set for residential areas. This is important as recent experiences highlight the increased fatalities in high-density areas, especially when there are no open spaces available for evacuation purposes. • Maximum “plot coverages” can be set to guarantee some open space within a plot. A plot coverage of 60% in a plot of 400 m2, for example, would translate into a maximum240 m2 of roof area, leaving 120 m2 as open space. This is an important disaster mitigation tool as it can be used to force people to allow room for a garden where they can go in the event of an earthquake. In the case of single-family dwellings, minimum plot sizes can be set in terms of plot area as well as minimum width and width/length relationships. For example, current regulations allow a minimum width of 6 m and a maximum width/length relationship of one to seven. This tool could be used to avoid extremely long passages that could make evacuation to the roads difficult. In the case of Maximum building height, it is also an important aspect in earthquake mitigation.

One important aspect of a zonation regulation relates to what the law describes as “special zones”. These are zones where development should be contained or avoided. Amongst the cases mentioned are airports, building of an historical heritage, natural resource conservation and flood-prone and “dangerous” areas. Interestingly, there is no elaboration on what is meant by “dangerous” areas. Even though one could argue that natural hazards can be included under the heading “dangerous areas”, the Urban Planning Law is somewhat vague in terms of natural disaster mitigation. It would seem that this law has not been updated to reflect current views and priorities which were agreed upon internationally and supported by leading organisations such as the United Nations and the World Bank.

Physical Characteristics of the Planning Area

Physical Characteristics of the Planning Area

a) Physiography: The Terrain of the area is generally plain with a gradual slope varying between 0.2-0.1 percent from northeastern to southwest. The maximum altitude is 204 meters above MSL near the Parthala Khanjarpur village in the northeast and the minimum elevation is 196 meters above MSL near the Gathi village in the southwestern part of the area. According to the Topographic sheet published by a Survey of India, the whole of Noida is surrounded by 200 m. It should be noted that the general level of the site is lower than the high flood level of the Yamuna river. It is only due to the construction of the embankment along the rivers Yamuna and Hindon that the flooding of the area is prevented.

However, the general low level of the site is a constraint for effective storm water and sewage disposal. For this reason, the general sanitary and hygienic conditions of the area are relatively poor.

b) Soil: Generally alluvial types of soils are found in the area. Therefore, contiguous agricultural fields interspersed with the open scrub and sparsely dotted trees are characteristically seen near the rural settlements in the area. There are three types of textures of soil particles found in this study area, which are Loam to Clay Loam, Sandy Loam to Loam and Sandy Loam Figure 2. c) Climate: Climatologically, this area resembles the central part of India and, therefore, experiences two extreme types of climate. The summer season stretches from March to June with the maximum temperature shooting up to 43.7 degree Celsius. During the winter period, this extends from October to February, the minimum temperature fall to less than 4 degree Celsius. The Monsoon season starts in the region from the last week of June and continues till the end of September with a normal annual rainfall of 132 cm. d) Drainage: The planning area is bounded by the Hindon in the east and the Yamuna in the west. Apart from these two main rivers, the area has a number of drains, which are perennial as well as non-perennial in nature. Hence, it is

In the north-western portion of the existing city of Noida, a major constructed drain, namely, the Hindon cut, is flowing, and is used by irrigation authorities to divert excess flood waters of Rohini into the Yamuna. This cut merges with the Yamuna river near the western municipal boundary of the township. Two other major drains exist in the area. One flows through the Sectors 14, 15 and 16 and falls into the river Yamuna south- west of Sector 16. The other drain, namely the Noida Drain, flows in the southern part of the area and finally falls into the Yamuna river upstream of the Yamuna-Hindon confluence point. This drain is presently being used as an outfall channel for drains servicing most parts of the Noida city. In this part of the area, besides the Noida drain, several ox-bow shaped water bodies and a dried left out channel of the Hindon are also found to exist. The query that comes to mind is that such a city, which is in a low lying area, basically a river catchment area has been developed by constructing embankments from all three sides, i.e. from the river Yamuna, the river Hindon and in the northern side by the Hindon cut. What will happen to such a flood prone city, when a flash flood comes or will it be able to sustain a rainfall of high intensity? Are there any scenarios of local flood situations? Has the Landuse Plan of Noida taken care of local floods? After studying the time-series data of rainfall over a period of time (Table 1) generated by the Indian Meteorological Department, Pune, India, on that basis I tried to generate scenarios (Table 1) of what will happen when a rainfall of maximum intensity, and lower than the maximum intensity, falls.

What is the critical intensity of rainfall that the city can sustain? The scenarios are generated for the latest Landuse map of Noida, which was updated through satellite images. Subsequently, same rainfall data will be used to generate scenarios for the year 2021.

Rapid urbanization is proceeding and pushing up the demand for various land uses mainly residential, commercial, industrial etc. Indeed land is the essential ingredient in this process as in all urban growth. This growth has been associated with increasing pressure on land for human settlements and related urban services. The problem in Noida, like most developing areas, is not a shortage of developable land, but the ineffective and unplanned mechanisms they use to ensure supply of suitable land for urban expansion. The trend of a development of this nature bears a heavy impact on the urban land development as is evident from the horizontal expansion of urban centres. As in the case of Delhi, the increased developmental pressure on peripheral agricultural lands in immediate surroundings of urban centres has further aggravated the problem of conservation and management of the natural environment. The present urbanization has paid insufficient attention to the environment in developing countries. As a result of that the ecologically valuable agricultural lands are converting to urban development like sector 27 of Noida without consideration for the environment. The Landuse breakup of the Noida city for the year 1998 is as shown in Table 2.

Disaster Management Calculation has been done by using Rational Formula

Q = 1/36 X CIA

Discharge Q is calculated for the years, 1958, 1982 and 1995. For example a calculation for 1958 = 793.86 m3/sec where the Intensity of Rainfall is 2.218 cm/hr Since Q> Qw, means that storm water drains cannot drain the whole rainwater. Total volume of water, which will runoff from the surface in 24 hours is V1 = 793.86 X 3600 X 24 = 68589504 m3 Total volume of water, which will drain through storm water drain in 24 hours is V2 = 674.87 X 3600 X 24 = 58308871 m3 Total volume of water accumulated in 24 hours in Noida is V3 = V1 - V2 = 10280632 m3 Using Meyer’s Formula, E = 0.06475 cm/day

E = Km (es - ea)[1 + Vg/16]

Total volume of water evaporated in 1 day = 20316 X 10 X 0.06475 VE = 131546.1 m3 Finally, Volume of water that will generate the local flood in Noida in 24 hrs is VF = 10280632 -131546 = 10149086 m3 If we divide this volume VF by the catchment area of Noida i.e. by 20316 m2, we get approximately 5 cm height of local flooding. Similarly, the other scenarios have been generated for 1982 and 1995 (see appendix I and II). The analysis is simulated in Microsoft Excel to give results for different intensities of rainfall. Calculation of Critical Intensity of Rainfall (Ic) For a no local flood scenario, Q = Ow After calculation, Ic = 1.885 cm/hr The scenarios for Noida 2021 have been generated and the results have been put in the computer. NOTE: - The worst case was in 1995, the year in which Delhi suffered a devastating flood. It rained with an intensity of 7.83 cm/hr for 1 hr and 45min. The calculation shows that it will create the same local flood scenario in Noida

The Ecological imbalance which has been created due to the abuse and overuse of environmental services in the city, has left a very thin line between natural and man made disasters. The city is subjected to congestion with a high density of population living in poor sanitary conditions. The degradation of these two worsened when the city started developing across its natural two boundaries. The rivers Yamuna and Hindon have been turned more or less into a drain and do not carry clear fresh water any more. Why have we destroyed our natural heritage, the ridge and the river, and what are we leaving behind for future generations? Nature cannot take more abuse, hence the degradation caused to the environment of the city has to respond in terms of its wrath and it is invariably the irresponsibility of the authorities and the people who are totally insensitive to human life who are blinded by the haves and have-nots of economics.

people who cannot meet even their daily necessities cannot be expected to take sufficient safeguards against natural disasters and combat various epidemics that usually follow such occurrences. The people who are poor migrants have their proneness increased by disasters because, by the process of elimination, they are forced to live in low lying areas subjected to frequent flooding and seismic vulnerability (because of poor and dilapidated housing conditions). Noida cannot sustain a rainfall of equal to or greater than an Intensity of I = 1.885 cm/hr. From the scenarios of 1998 and 2021, it is clearly evident that with the increase in Urbanization, surface runoff, as a result of the intensity of local flooding is increasing. For future development, in order to avoid local flood scenarios the surface runoff coefficient should not exceed 0.5298. The land use distribution should be modified by giving more percentage to green areas. This will help in water percolation and slow down the speed of surface water.

The Ecological imbalance which has been created due to the abuse and overuse of environmental services in the city, has left a very thin line between natural and man made disasters. The city is subjected to congestion with a high density of population living in poor sanitary conditions. The degradation of these two worsened when the city started developing across its natural two boundaries. The rivers Yamuna and Hindon have been turned more or less into a drain and do not carry clear fresh water any more. Why have we destroyed our natural heritage, the ridge and the river, and what are we leaving behind for future generations? Nature cannot take more abuse, hence the degradation caused to the environment of the city has to respond in terms of its wrath and it is invariably the irresponsibility of the authorities and the people who are totally insensitive to human life who are blinded by the haves and have-nots of economics. CONCLUSION Noida and Greater Noida face the same challenges as other fast developing areas of the developing world. How do we balance limited resources with the strong desire for personal development and governmental economic need? The

people who cannot meet even their daily necessities cannot be expected to take sufficient safeguards against natural disasters and combat various epidemics that usually follow such occurrences. The people who are poor migrants have their proneness increased by disasters because, by the process of elimination, they are forced to live in low lying areas subjected to frequent flooding and seismic vulnerability (because of poor and dilapidated housing conditions). Noida cannot sustain a rainfall of equal to or greater than an Intensity of I = 1.885 cm/hr. From the scenarios of 1998 and 2021, it is clearly evident that with the increase in Urbanization, surface runoff, as a result of the intensity of local flooding is increasing. For future development, in order to avoid local flood scenarios the surface runoff coefficient should not exceed 0.5298. The land use distribution should be modified by giving more percentage to green areas. This will help in water percolation and slow down the speed of surface water.

INTRODUCTION World Development Report (1986) defined food security as “access by all people at all times to enough food for an active, healthy life.” World food problems involve complex interactions among food production, population growth, poverty, environmental effects, and economic and political systems. Producing food at a faster rate than population growth will not solve hunger problems unless the poor have enough land to grow their own food or enough income to buy the food they need. Chronic hunger and catastrophic famine are due to the lack of access to food, but not a lack of food. Global food production has increased substantially over the past two decades, but producing food and other agricultural products by conventional means uses more soil, water, plant, animal, and energy resources, and causes more pollution and environmental damage, than any other human activity. To feed the 8.5 billion people projected by 2025, we must produce and equitably distribute as much food during the next 20 years as was produced since agriculture began about 10,000 years ago. The Indian planners, right from the beginning realized the need to attain self-sufficiency in foodgrains as one of the important goals of planning. The Government realized that food surplus countries used their food-surplus as a weapon to force food deficit countries to submit to their dictates. When India suffered two very severe droughts in 1965 and 1966, the American President Lyndon Johnson, in order to teach a lesson to India, restricted food aid to a monthly basis under the P.L. 480 programme. This was done to force India not to condemn American aggression in Vietnam.

Main Focus of the Study The main focus of the study is to deal with the following issues : i) Global Warming and Crop Production ii) Vagaries of Monsoon and Food Production iii) Population Growth and Food Supply iv) Strategies for Food Security Global Warming and Crop Production Global warming has emerged as one of the most important environmental issues ever to confront humanity. This concern arises from the fact that our everyday activities may be leading to changes in the earth’s atmosphere that have the potential to significantly alter the planet’s heat and radiation balance. It could lead to a warmer climatic in the next century and thereafter adverse effects are possible in agriculture and other fields. The presence of carbondioxide in the atmosphere is also known as a ‘green house gas and helps to retain the incoming heat energy from the sun, thereby increasing the earth’s surface temperature. Of course, carbondioxide is only one of several such greenhouse gases in the atmosphere. Others include methane, nitrous oxide and water vapour. However, carbondioxide is the most important greenhouse gas that is being affected by human activities. Carbondioxide is generated by a multitude of processes ranging from animal and plant respiration to the burning of any kind of fuel containing carbon, including coal, oil, wood and cow dung. For a long time, human activities that generated carbon dioxide caused only a small perturbation in the natural cycle of the gas. However, since the Industrial Revolution, when our usage of fossil fuels increased dramatically, the contribution of carbondioxide generated from human activities has grown large enough to constitute a significant perturbation of the natural carbon cycle. The concentration of carbondioxide in the earth’s atmosphere was about 280 parts per million by volume (ppmv) in 1750, before the Industrial Revolution began. By 1994 it was 358 ppmv and rising by about 1.5 ppmv per year. If emissions continue at the 1994 rate, the concentration will be around 500 ppmv, nearly double the pre-industrial level, by the end of the twenty-first century. The Intergovernmental Panel on Climate Change (IPCC), Paris, in February 2007 stated that under the existing scenarios of economic growth and development leading to greenhouse gas emissions, on a worldwide average, temperatures would rise by 1 to 3.5 degrees Celsius by the year 2100, and the global mean sea level by about 15 to 95cm. It is likely that changes of this magnitude and rapidity could pose severe problems for many natural and managed ecosystems, as well as important economic sectors such as agriculture and water resources. Indeed, for many low-lying and deltaic areas and small islands, a sea level rise of one meter could threaten a complete loss of land and the extinction of habitation.

The manner is which progressive global warming may affect the Earth’s ecosystems in the future is difficult to predict. However, recent studies have shown how higher CO2 levels and slightly warmer global temperatures have affected the biosphere. Some of the studies have demonstrated that, since the 1960s, warmer average temperatures have brought an earlier spring and later winter over the higher latitude areas of the northern hemisphere, advancing the growing season by about 7 days in the spring and extending it about 2 to 4 days in the autumn. This extended growing season, along with elevated levels of CO2, has spurred greater plant growth over a wide swathe of territory, including Alaska, Canada, Scandinavia, northern Europe and northern sections of Russia and China. About 10 per cent reduction of snow cover is associated with warmer temperatures in higher latitudes, which probably translates to quicker warming of the soil and a faster start to spring growth. The increased CO2 available probably also adds to the photosynthesis rates over the growing season. The increase in plant growth may be great as 10 per cent in the affected regions and provides some of the best direct evidence so far of a large-scale eco-system response to climate change. This response is not likely to be as universal, however. Higher temperatures and less rainfall in some areas may decrease soil moisture levels and actually suppress growth and agricultural yields. Moreover, scientist have long predicted that as global temperatures get warmer, the geographic ranges of plants and animal species will shift towards the poles or to higher elevations to maintain their preferred temperature conditions. Without suitable temperature conditions, the germination of seeds and growth of plants is retarded. Temperature regulates all the chemical and physical processes of plant metabolism. The metabolic process begin at a certain minimum temperature and increase with the rise in temperature until they reach a maximum at a temperature called the optimum. The ideal temperature conditions for crop production are between 18.3 and 23.90C. Due to global warming the optimum temperature required for any crop will rise which will effect the metabolic activity of the crop which will create a food problem in future. Vagaries of Monsoon and Food Production India is one of the wettest countries in the world, with an average annual rainfall of 11 inches.

Table 1 depicts that the annual rainfall over the entire country represents around 400 million hectare metres of water. Of this, about 70 million hectare metres are lost immediately due to evaporation and 215 million hectare metre percolate into the soil. Thus, 115 million hectare metres are left which flows into the river systems. The entire surface water cannot be utilized because of the topography, the water flow characteristics, the soil conditions and climate. In 1974 the surface water utilization was roughly 25 million hectare metres. It is estimated to increase to 70 million hectare metres by in 2025. It has been observed that the rainfall has gradually declined during the past few decades. The average rainfall during the period 1930-60 was 21.11 inches which fell to 12.72 inches by the period 1970-85. The monsoon has been adversely affected by the physical and economical development in the area during the past few decades leading to environmental pollution and also because of deforestation. When the new agricultural strategy was introduced in the early 1960’s, it was hoped that the trend of the rising output of foodgrains would continue. The record achievement of 108 million tonnes of foodgrains in 1970-71 was hailed that the green revolution had materialized and imports were immediately stopped. The euphoria was cut short in 1972-73 when production of foodgrains slumped to 95 million tonnes. Sharp fluctuations in foodgrains output were observed in the later years. From a low level of 100 million tonnes in 1974-75, foodgrain output rose gradually to 132 million tonnes in 1978-79. There was a steep decline in production in the next year due to adverse weather conditions; the foodgrain output in that year was 109 million tonnes which was almost the same as 1970-71 output. After many fluctuations, the output of foodgrains rose to 176 million tonnes in 1990-91 and touched 212 million tonnes in 2001-02 (Table 2). On account of extensive drought conditions, the output of foodgrains declined steeply to 174 million tonnes during 2002-03 (decline of 38 million tonnes) as compared with the previous year.

The erratic monsoon rainfall in 2004 caused a substantial fall in the kharif foodgrains production (Table 3). The table shows that the kharif foodgrains production in 2004-05 was 102.9 million tonnes, which is short of last year’s production by 9 million tonnes. Good post-monsoon rains, especially during October 2004, which helped a build up of soil moisture, and the prevalence of cool weather conditions through the rabi season, improved the production of rabi crops to 103.5 million tonnes, up 3.5 million tonnes from the last season. The overall foodgrain production in 2004-05 was 206.4 million tonnes, which is nearly 6 million tonnes less than the last year. Unfavourable weather conditions in the years 2002-03 adversely affected the agricultural production. The foodgrain production in 2002-03 was 174.2 million tonnes, which is short of last year’s production by nearly 39 million tonnes. The table further shows that there is a shortfall in the production of both coarse cereals and pulses, which are essentially rain fed crops. The decline of nearly 6 million tonnes in the production of coarse cereals is largely responsible for the decline in the overall foodgrains production in the years 2004-05 due to an erratic and delayed monsoon with an uneven distribution of rainfall over time and regions.

The erratic monsoon rainfall in 2004 caused a substantial fall in the kharif foodgrains production (Table 3). The table shows that the kharif foodgrains production in 2004-05 was 102.9 million tonnes, which is short of last year’s production by 9 million tonnes. Good post-monsoon rains, especially during October 2004, which helped a build up of soil moisture, and the prevalence of cool weather conditions through the rabi season, improved the production of rabi crops to 103.5 million tonnes, up 3.5 million tonnes from the last season. The overall foodgrain production in 2004-05 was 206.4 million tonnes, which is nearly 6 million tonnes less than the last year. Unfavourable weather conditions in the years 2002-03 adversely affected the agricultural production. The foodgrain production in 2002-03 was 174.2 million tonnes, which is short of last year’s production by nearly 39 million tonnes. The table further shows that there is a shortfall in the production of both coarse cereals and pulses, which are essentially rain fed crops. The decline of nearly 6 million tonnes in the production of coarse cereals is largely responsible for the decline in the overall foodgrains production in the years 2004-05 due to an erratic and delayed monsoon with an uneven distribution of rainfall over time and regions.

Rice as a major foodgrain is life for thousands of millions of people. In Asia alone, more than 2,000 million people obtain 60 to 70 percent of their calories from rice and its products. It is of significant importance for food security in an increasing number of low-income food-deficient countries. However, rice production is facing serious constraints including a declining rate of growth in yields, depletion of natural resources, labour shortages, genderbased conflicts, institutional limitations and environmental pollution. Overcoming hunger, poverty and malnutrition, while protecting the environment – requires collective action. The diversity of the regions, people, and resources connected within the world’s rice-based systems requires a diverse approach for global rice-based development that includes participation from the local to the international level. The United Nations General Assembly had, after having recognized the importance of this crop, declared 2004 as the “International Year of Rice.” Population Growth and Food Supply The Green Revolution started in the mid-sixties with the introduction of high yielding varieties of seeds, chemical fertilizers and pesticides in our country to boost up agricultural production. In the meantime, the foodgrain production significantly increased from 50.82 million tonnes in 1951 to 195.9 million tonnes in 2001, but per capita food availability (PCFA) did not increase much more and it slightly changed from 395 grams to 459 grams, which is far behind than the requirement. There was some good sign which came in the decade of 1991 when the foodgrain production increased by more than the population and ultimately the PCFA crossed 500 grams (Table 4).

The intensive use of fertilizers affect the fertility of the soil and pollutes the ground water. That leads to a formation of wasteland and desertification. This has a direct effect on the livelihood of the rural poor and sustainable human security, thus, there is a need for an ecological sustainable agriculture.

We must orient our agricultural policies in the interests of agricultural growth with emphasis on sustainability and equity on the following grounds : (i) Output and area under coarse cereals has shown negligible improvement: – Neither area nor production of coarse cereals showed any significant improvement. Sufficient attention was not paid so far to develop better HYV strains of these crops. Since major inputs were directed towards wheat and rice, coarse cereals remained neglected and to improve their production should be a major thrust area now. (ii) Stagnation in the output of pulses: In most years the production of pulses has been stagnant at around 13 to 14 million tonnes. The per capita consumption of pulses, which was 69 gm per day in 1971 has come down to 36 to 37 gm per day now. This sharp decrease in the consumption of pulses is a cause of serious concern, more so for the poor for whom pulses are the major source of protein. Pulses are mostly grown under unirrigated conditions on poor soils and with low inputs. Out of about 23 million hectares of area under pulses, only 2 to 3 million hectares are irrigated. Pulses do not require large dozes of fertilizers and pesticides. The development of short duration varieties and improved dry farming technology has raised new hopes of raising the production of pulses. (iii) New Strategies of irrigation and water management: The total foograin production from a gross area of 163 to 165 million hectares was around 212 million tonnes in 2001-02 (as against the Ninth Plan target of 234 million tonnes for that year). Our average foodgrains production is about 1.3 tonnes (or 13 quintals) per hectare. If India is to meet the needs of its growing population of over 1,000 million people it must produce 240 to 250 million tonnes of foodgrains per year. This will necessitate the adoption of new strategies of irrigation. The total available water reserve is of the order of 100 million hectare metres (mhm) during the next 12 to 15 years. Since water is a scarce resource, it is vitally necessary that emphasis be shifted on its more efficient use. As

things stand today, 90 per cent of water available is allocated to irrigation. The target should be to reduce water use for irrigation to 77 percent of the total available water in the next 10 to 12 years, so as to meet the rising demand for water for industrial and municipal needs. In major irrigation projects, there is frequently over-irrigation, with its adverse effects on production. For instance, farmers use 1,500-3,000 mm of water for paddy, as against the requirement of only 800mm. Moreover, the absence of proper channels to take water to various fields leads to water logging and makes the land saline or alkaline. Use of sprinkler irrigation can bring about 30-35 per cent of saving in water use. This should be used in all closely spaced crops like millets, groundnuts, pulses and wheat. Drip irrigation is suitable for all row crops and can result in a water saving of 50-70 per cent, simultaneously raising yield by 60-70 per cent in various crops. It helps in the economical use of water and is specially suitable for irrigation by wells. (iv) The use of bio-fertilizers has to be expanded: Recent researches in biotechnology and genetic engineering have demonstrated that certain microorganisms such as bacteria and blue green algae can act as nitrogen fixers and provide nutrient to crop-plants. The most commonly used bio-fertilizer is Rhizobium which colonizes the roots of specific legumes to form root nodules. These nodules act as factors of ammonia production. The Rhizobiums legume association can fix 100-300 kg of nitrogen per hectare in one crop season and even leave substantial quantities of nitrogen for the next crop. The great breakthrough in nitrogen generation by micro-organisms, for which the bill is paid by nature, is a great advance in agricultural research that promises a second green revolution. (v) Emphasis should shift to dry farming: Out of a total cultivated area of 163 million hectares in India, dry farming is carried on in 100 million hectares i.e. in 60 per cent of the total arable land. But the contribution of dry land farming to agricultural production is less than 30 per cent. About two-thirds of dryland farmers own less than two hectares and even this is available in scattered and fragmented holdings. Since the country has to carry on with dryland farming for many years to come, it is vitally necessary that dry-farming technology be developed, so that the possibilities of raising the potential output of vast dry-land areas can be exploited. For this purpose, problems of different dryland areas have to be studied and region-specific technology has to be developed. The moderate use of fertilizers, improved seeds and better conservation of rain water and its judicious use, can contribute to a 40 to 50 per cent increase in yields in rain-fed areas. (vi) Agricultural Research: Agricultural research is presently being conducted by the Indian Council of Agricultural Research, various Agricultural Universities and other institutions for evolving high-yielding varieties of seed for different crops. Considerable success has been achieved in the case of

Therefore there is a vital need to save human life as well as animal lives, but there is a question which arises of “how can we control them and what kind of suggestive measure should we take to reduce the vulnerability from landslides”.

The possibility of suffering from the hazard can cause injury, disease, economic loss, or environmental damage. Today both life support systems and the productivity of land water systems are increasingly threatened by natural hazards by human pressure in Uttaranchal. Certain regions are over shooting in their carrying capacity in producing quite dangerous conditions especially tropical and temperate region in the state. The down slope movement of large volumes of surface materials under gravitational influences is an important environmental hazard, especially in mountainous terrain Rapid movements cause most loss of life and damage: slow movements, including human induced land subsidence, have less potential to kill but can be costly.

It is well known that landslides and debris flows are very harmful to mankind, in terms of life loss and economic loss. Therefore there is a vital need to save human life as well as animal lives, but there is a question which arises of “how can we control them and what kind of suggestive measure should we take to reduce the vulnerability from landslides”.

This paper suggests how to overcome landslide hazards and how to reduce the economic loss and the loss of human lives.

[snow covered with steep slopes] in the north. The geological studies indicate that the Himalayas are susceptible to geo-hazards viz. earthquakes, landslides, floods etc. due to the continuing vertical uplift of 1 cm/year in the Shivalik and 2 cm/year in the lower ranges of the main Himalayan region. The uplift movements have not yet ceased for this region and it is still unstable and susceptible to earthquakes. Tehri Garhwal 1905 and subsequent shocks in the 1980s and 1990s have rocked the Karn Prayag and Raudra Prayag. The Shivalik Hills are composed of highly unconsolidated deposits, which easily lend themselves to erosion. These hill masses are closely packed often forming minor watersheds. The Topography of this region gives the look of a cup shaped depression with deeply incised gullies backed by the denuded harder strata upstanding here and there. The heavy load of sediments washed down by the beat of the rain chokes the streams and numerous rills down the slopes. Therefore, landslides have become a very common feature due to heavy rainfall, indiscriminate deforestation in the catchments and the upper reaches of the Ganga river basins. The combination of very high mountains and flat valleys below are the breeding ground of many cloudbursts in many parts of the Himalayan region. Apart from this, the resource base on which mountain people depend has deteriorated at an accelerating rate. Forest has been cutoff, vegetation cover removed and steep slopes have become severely eroded. Together with exploitation, the impacts of population pressure and inappropriate technologies have severely degraded the mountain environment. These are the result of an un-mistakable system of engineering, un-sustainability of the current patterns of resource use and production practices. The overall situation is both a cause and concern for reappraisal of conventional development approaches to maintain areas in general and environment in particular. The Indian government has taken hazard occurrence as the first priority, but the little efforts being made fall short of the requirement of money and material. There is a need for an integrated multi-disciplinary approach to the planning based on sound environmental and ecological aspects for the rehabilitation of effected people and even the command area is prone to natural hazards. Their management includes administrative, political and economic actions to decide whether and how to reduce a particular risk to a certain level. Nature of Problem There can be few countries where mass movement processes do not exist, and the landslide risk is increasing worldwide as land hunger forces the new development on to unstable slopes. According to Jones (1992), it is an under recognized threat because the impacts tend to be frequent and small-scale, whilst the process itself is often attributed to other hazards, such as earthquakes and rainstorms. During the early 1970s, an average of nearly 600 people per year were killed by slope failures worldwide but, twenty years later, the figure was several thousand (Brabb, 1991). Perhaps as many as 90 per cent of these deaths

occur on the Pacific Ocean region, which is particularly susceptible to mass movements because of the varying combinations of rock type, steep terrain, heavy typhoon rainfall, rapid land use change and high population density. The main cause of increased deaths has been the expansion of unregulated settlements onto unstable slopes in many third world cities. For example, in Caracas, Venezuela, the number of urban landslides increased from less than one per year up to about 1950 to reach 35 – 40% per year in the 1980s (Jiminez, 1992). The death toll from mass movements is still comparatively low in most Medium Developing countries. In the USA the annual mortality runs at 25 - 50 people and it has been estimated that, for landslides alone, some 22 per cent of the population are exposed to high hazard conditions while another 20 per cent are exposed to moderate hazard conditions (Petak, 1989). As with many other environmental hazards, it is urban areas, which are most vulnerable because of the large populations at risk (Alexander, 1989). Economic losses due to landslides total more than One billion US $ per year in several counties, including Japan. Other countries with large but un-quantified losses include Indonesia, China and the former Soviet Union. In Italy it has been estimated that over 1,000 urban centers are threatened by landslide activity. In addition to direct damage mass movement hazards cause a variety of indirect losses such as road blockages, flooding due to landslide dams across rivers, reduced agricultural and industrial production, and lower property values. Snow avalanches are special types of mass movement. They are common features of mountainous terrain throughout arctic and temperate regions whenever snow is deposited on slopes steeper than about 20°. The USA alone suffers 710,000 potentially damaging avalanches per year, although only about 10 percent harm humans or property. In the past, casualties were suffered by travellers passing through the mountains as well as the miners located in permanent, but badly sited, mining settlements. The Andean countries are notable for avalanche related mining disasters. The worst avalanche disaster in the USA occurred in 1910 in the Cascade Range, Washington, when three snowbound trains were swept into a canyon with the loss of 118 lives. Historically, the avalanche problem has always been more severe in Europe then North America because the population density in higher in the Alps than in the Rockies. Switzerland has a relatively large number of avalanche deaths amounting to some 20-30 fatalities per year. Snow avalanche problems have risen as winter recedes. This is mainly due to the greater use of winter recreation and the associated development of ski centres and other holiday resorts. For example, the town of Vial, Colorado, located at an elevation of 2,500 m, was founded, as a resort community only in 1962. The construction of alpine facilities often requires the removal of timber from the surrounding slopes. If left intact the trees would help to stabilize the snow cover and protect the new roads, railways and power lines which are invading these areas.

As with many other environmental hazards, it is urban areas, which are most vulnerable because of the large populations at risk (Alexander, 1989). Economic losses due to landslides total more than One billion US $ per year in several counties, including Japan. Other countries with large but un-quantified losses include Indonesia, China and the former Soviet Union. In Italy it has been estimated that over 1,000 urban centers are threatened by landslide activity.

The construction of alpine facilities often requires the removal of timber from the surrounding slopes. If left intact the trees would help to stabilize the snow cover and protect the new roads, railways and power lines which are invading these areas. Avalanche problems in the rocky mountains beset the Canadian Pacific Railway and the Trans-Canadian Highway together with

sections of US Highways. The Trans-Canadian Highway alone crosses nearly 100 avalanche tracks in 145 km. It has been estimated that at least one motor vehicle is under a major avalanche path at any given time. NATURE OF LANDSLIDES Landslides are down slope movements of rock and soil along slip surfaces. They are associated with a disturbance of the equilibrium, which normally exists between stress and strength in material resting on slopes. The relationship between stress and strength is determined by factors such as the height and steepness of the slope and the destiny, strength cohesion and friction of the materials on the slope. Hill slope instability occurs when the strength of the material comprising the slope is exceeded by a down slope stress. The internal cohesion is produced by the interlocking, or sticking together, of granular particles, particularly in clayey soils and rocks, that enables the material to rest at an angle. Some materials, such as dry sand, are cohesionless. Cohesion is independent of the weight of material above the surface. The internal friction is the resistance of particles of granular soil to sliding across each other. The friction component of shear strength depends on the weight of material above the surface. In turn, these factors will depend on the weight, or loading, on the slope and the moisture condition. The term landslide covers most down slope movements of rock and soil debris that have become separated from the underlying part of the slope by a shear zone or slip surface. The type of movement, which may include falling, sliding and flowing, depends largely on the nature of the geological environment, including material strength, slope configuration and pore water pressure. Jones (1995) asserted that slope failure will become an increasingly important hazard, especially in the LDCs country and identified several types of landslide terrain 1. Areas subjected to seismic shaking earthquakes can promote widespread land sliding, which often occur as thousands of individual slides, as in 1950 Assam, India, as earthquake when over 50 billion m3 of material was displaced over an area of 15,000 km2. Major landslides also occurred after the 1991 in Uttarkashi and Chamoli of Uttaranchal earthquake and very recently in June 2004, there was a major landslide in Kumaun region of Uttaranchal, which claimed more than five people in the area, and 26 were injured. 2. Mountainous environments with high relative relief, high or steep slope terrain, such as in the northern portion of the Himalayas and north-western portion of the Himalayas, produces perhaps one catastrophic rock fall per decade in the Himalayan ranges. These spectacular slope failures comprise huge masses of material (up to 100,00,00,00,000 m3), which, at least in the initial stages, travel near vertically at high velocities over long run-out distances. 3. Areas of moderate relief suffering severe land degradation. Readily erodible soils on slopes subject to land degradation caused by deforestation or

overgrazing have the potential for gully expansion and land slipping in the middle of the Himalayas. Over the centuries, about 160 villages in Himachal Pradesh and near about 240 villages in Uttaranchal Himalayas have been abandoned because of this process. 4. Areas covered with thick sheets of loss. Any mantling of an existing ground surface with finely grained deposits, such as wind- blown losses or tephra, is likely to lead to a sheer zone at the junction of the two materials and the formation of flow slides in the loose deposits. The loess plateau of central China and the Shillong plateau of northeastern Himalayas are the classical location. 5. Areas with high rainfall inputs. The areas that regularly experience rainfall from monsoons or tropical cyclones are rock weathering and can penetrate tens of metres below the ground surface. For example, in parts of the lower Himalayas and north-east Himalayas of Meghalaya weathered material has moved down slope to cover the bedrock to a depth of more than 10 meters. Throughout the humid tropics, these deep and porous mantles are prone to landslides. ROCK FALLS IN HIMALAYAN REGION This is a movement of debris flow or rock falls through the wind and soil erosion. The simplest type of rock movements occur on steep slopes, where bedrocks are weak, such as joints, and the bedding of exfoliation surfaces are present. Rock falls are presumed to fall directly off cliff faces, rather than to slip along a joint or bedding plane, although both types of movement may occur. The presence of water in clefts and fissures is highly influential, especially in the mid-latitudes where regular freeze-thaw cycles progressively weaken the rock mass by increasing such openings as in Chamoli, Pithoragarh, and the Uttarkashi district of the Uttaranchal Himalayas. Earthquakes induce many of the largest rock falls but more spontaneous slope instability also occurs, especially in closely jointed or weakly cemented materials on slopes steeper than about 40°. The greatest rock fall hazard exists when joints and bedding planes are inclined at a steep angles, as in the highly folded rocks common in major mountain chains as in the Himalayas and Rockies. In these areas the slides took place across bedding planes in a steep anticline formed in the well-jointed limestone of Garhwal Himalayas, which was also subject to mining activity. Groundwater seeping into the joints dissolved the limestone and enlarged the fractures. During the winter this water froze and wedged the rock apart, further weakening the structure. The resulting debris destroyed the southern end of the small towns on the hill slopes.

the driving forces on a slope may be either physical or human induced. • An increase in slope angle, which may occur if stream erode the bottom of a slope or if the slope is steepened by the building work. Jones et al. (1989) has described how the cutting of a road into the base of the slope during 1984, which left exposed faces 25 m high and colluvium standing at an angle of 55° unsupported by anything other than a 3 m masonry wall, led to the Catak landslide disaster in Turkey in which 66 people died in 1988. • Removal of lateral support at the foot of the slope again caused either by natural mass wasting processes or by building activity. • Additional weight placed on the slope by the dumping of the waste or house construction. Residential development not only adds weight to the slope through the buildings themselves but also through excess water supplied from landscape irrigation and seepage from swimming pools and sewage effluent systems. • Removal of vegetation either by wildfires or through human activities, such as, logging, overgrazing or construction and hyper urbanization. Surface materials become looser because of the loss of soil binding by roots and the slope is also more exposed to the erosive action of surface water through the loss of plant cover. • Local shocks and vibration, which can occur naturally from seismic activity or from the operation of heavy construction (road construction works in Himalayas) machinery.

An increase in pore pressure in the slope materials, especially along with a sloppy surface. This is the most important single factor and explains the close relationship which exists between shallow- seated landslides, debris flows, and rainstorms. Unfortunately, the detailed interaction of rain- water and soil behavior is rot fully understood and it remains difficult to predict landslides on a site-specific basis. In unsaturated material that is not totally dry, the internal voids or pores will be filled with gas (air and water vapor) and some liquid water. If the slope then experiences additional loading, perhaps as a result of building construction, the mineral grains will be able to slide into a more compact arrangement. Such compression increases the soil density and additional strength will result. However, if there is resistance to a denser configuration due to water in the void space, and rapid surface loading occurs relative to the permeability of the soil, then the additional load is transferred into the pore water causing an increase in the pore- water pressure. In turn, this reduces the friction component of strength and down- slope movement may occur. An increase in slope angle, which often occurs when developed slopes are over steepened by cutting into the base, a process which increases the driving forces.

An increase in pore pressure in the slope materials, especially along with a sloppy surface. This is the most important single factor and explains the close relationship which exists between shallow- seated landslides, debris flows, and rainstorms. Unfortunately, the detailed interaction of rain- water and soil behavior is rot fully understood and it remains difficult to predict landslides on a site-specific basis. In unsaturated material that is not totally dry, the internal voids or pores will be filled with gas (air and water vapor) and some liquid water. If the slope then experiences additional loading, perhaps as a result of building construction, the mineral grains will be able to slide into a more compact arrangement. Such compression increases the soil density and additional strength will result. However, if there is resistance to a denser configuration due to water in the void space, and rapid surface loading occurs relative to the permeability of the soil, then the additional load is transferred into the pore water causing an increase in the pore- water pressure. In turn, this reduces the friction component of strength and down- slope movement may occur. An increase in slope angle, which often occurs when developed slopes are over steepened by cutting into the base, a process which increases the driving forces.

Weathering processes, which promote the physical and chemical breakdown of slope materials. Certain clay minerals, such as montmorillonite expand when water is present and the behavior of these expansive clays has been implicated in the failure of many Himalayan hillsides (Griggs and Gilchrist). In addition, other natural processes may be involved. The burrowing action of soil animals or soil piping developments on slopes will lead to weakness and the possibility of land sliding. In most of the urban areas, landslides may be attributed to a combination of the above factors. The progressive human invasion of landslide hazard zones is not confined to the developed world. The need for improved transportation is leading to new road construction in terrain with a high probability of slope movement throughout the LDCs. In these areas limited resources may lead to inadequate hazard protection. For example, the 52 km long Dhahran – Dhankuta road, completed in 1981, provides a key north- south link within Nepal between the Ganges lowlands to the south and the hill villages to the north. The road crosses the unstable Himalayan foothills of East Nepal and is surrounded by long, steep valley-side slopes angled at 30-45° Engineering is difficult and expensive in such terrain and the road was built to a relatively low-cost specification. The road has since proved difficult to maintain because of cutslope failures and the blocking of culverts by debris.

STEPS TOWARDS HAZARD REDUCTION Insurance Private insurance against landslides and other mass movement hazards is not generally available in the USA, largely because of the risk of high losses. The unavailability of insurance can discourage development in hazardous areas but, because information about landslide hazards is not widely disseminated, many people remain unaware that they are at risk. Some limited insurance cover in the USA is provided through the national flood Insurance program, which requires areas subject to ‘mudslide’ hazards associated with river flooding to have insurance cover before being eligible for federal financial assistance. Unfortunately, technical difficulties in mapping ‘mudslide’ hazard areas have led to comparatively little use of this provision. In some countries, legal liability forms a growing basis for financial recompense after landslide losses. American jurisprudence recognizes civil liability for death, bodily injury and a wide range of economic losses, which may be associated with landslides. The classic defence of ‘Act of God’ carries decreasing credibility, and recent court judgments have tended to identify the developer, or the consultants, as mainly responsible for damage due to land failure. In some areas, such as Los Angeles County, local government agencies have shared the liability because it has been argued that the issue of a permit for residential development implies a warranty of safe habitation on the other hand, and it is difficult to envisage litigants as an adequate substitute for proper hazard–reduction strategies.

Disaster Management

LANDSLIDE MODIFICATION ADJUSTMENTS The ability to assess the probability of landslide risk at specific places is of considerable assistance in implementing mitigation strategies. General indicators include the structure and lithology of slopes, including the presence of weak rock types, clay – rich soils and slopes generally in excess of 25°. It is a challenge to translate these factors directly into terms suitable for risk assessment because of the high spatial variability in soil shear strength, which may be greatly affected by plant root systems stabilizing part of a slope, and the usual absence of any piezometric information, which would warn of increasing pore water pressures. Bernknopf et al. (1988) divided the Cincinnati metropolitan area into 100 m2 cells and devised a probability model from a combination of variables that represent the existing physical state of a hillside, the dominant landside mechanism in the area and the types of construction activities that can trigger landsides. The results showed that an uncritical application of the uniform building code to the whole area would not be cost–effective. Property damage from landslides usually leads to demands for engineering works to stabilize the slope. However, the human response to slope failure is often complicated by the statutory and funding distinctions, which are made between emergency and permanent works. Emergency response designed to protect public safety and prevent further immediate damage are usually undertaken satisfactorily but government funds are made available only very reluctantly for permanent slope stabilization. This may be because the specialized geo-technical information required is not available or because of the high potential cost to the public purse. Alexander (1987b) drew attention to inadequate geological advice and political muddle as contributory factors to the Ancona landslide disaster in Italy. It is a recurrent feature of all hazard mitigation that few publicly funded authorities are willing to pay for expensive defence work for private undertakings when large profits are to be made from property and land speculation. If these problems can be overcome, the stability of the slope may be improved by a variety of engineering techniques. Excavation and filling methods can be used to produce a more stable average slope. This type of reshaping is usually successful but becomes more difficult and expensive as the slide area increases. Specific techniques include unloading the head of a slide and loading the toe, with the replacement of failed material with lighter roads. Drainage, especially sub-surface drainage, can be equally effective where changes in pore water pressure have been caused by a rise in the water table. Drainage methods range from the removal of surface water and the drainage tension cracks to the insertion of trenches filled with gravel or horizontal drains. Properly designed and constructed drainage systems work well but others soon become clogged by fine particles.

Re-vegetation of slopes performs several functions. Plant roots help to bind soil particles together; the vegetation canopy protects the soil surface from rain splash impact and transpiration processes aid in drying out the slope. Whilst evergreen are generally better at providing an all-year canopy, deciduous trees are generally better conifers at removing excess soil moisture because they have higher rates of transpiration during the summer. However, it may be unwise to rely on vegetation for slope stability because of the possibility of fire or disease of the lifetime of a project. Restraining structures such as piles, buttresses and retaining walls can be helpful for slides covering limited areas, but they are generally too expensive for large, unstable slopes and the location of the property boundaries may also restrict this approach. Guiding structures near the base of the slope, such as diversion walls, can deflect small debris flows effectively. Other methods include the chemical stabilization of slopes and the use of grouting to reduce soil permeability and increase its strength. In some high-risk urban areas, like Hong Kong, slopes may be covered with materials such as chunam or gunite to reduce the infiltration and keep pore water pressure low. On some construction sites the freezing of mass moving soil has been successfully accomplished, and the freezing plant has been left in operation until the soil retaining structures were completed. Slope stabilization, along with hazard-resistant construction techniques, appears to be the most effective preventative strategy for controlling new development. In this context grading ordinances, such as the uniform building code adopted in India, are important tools. Along with soil compactation and surface drainage requirements, this act generally specifies a maximum slope angle of 2:1 for safe development. The basis for such a specification, which means a 27° slope, is that the natural angle of repose for dry sand is 34°, and therefore a 2:1 slopes allows for an element of safety over this. Building codes normally require developers to obtain permits before they embark on earthmoving projects on hazard-prone slopes. Ideally they also require reports from geotechnical engineers and engineering geologist on proposed building sites before a local authority approves plans. To work properly, this sort of system needs technically trained inspectors to enforce the regulations and levy development fees to become financially self-supporting. Olshasky ad Rogers (1987) cited the success of the city of Los Angeles, which introduced a grading ordinance as early as 1952. Before this date more than 10% of all building lots were damaged by slope failure. Initially, the ordinance required only soil testing but it has subsequently been strengthened.

and debris flows triggered by typhoon rainfall. Mitigation has been pursued through the construction of check dams, drainage systems and other physical controls in combination with development restrictions. In the landslide track and debris flow zone, various deflectors and retarding devices may be located. Large walls built on the earth, rock or concrete can be used to diverting the debris flow from its chosen path. The slope for diversion is limited, up to 15-20° from the original slide path have proved the most successful. In addition wedges pointing upslope can be used to avoid the slides and then divert the sections around vulnerable facilities, for example, electrical transmission towers or isolated buildings. Towards the slide zone other retaining structures, represented by earth mounds or small dams, can be useful as the slope angle declines and the debris flows lose the energy. Mounds are generally ineffective on slopes steeper than 20°. Direct protection structures, such as debris sheds and galleries, designed to pass the flow over key facilities such as transport lines, obtain the most complete defence against all kinds of slides. Slide sheds typically act as protective roofs and walls along with the roads and railways, but these structures are expensive and need careful design to insure that they are properly located and can bear the maximum debris resisted walls and mounds. In the longer term, there is some incentive to control the landslide hazard by re-afforesting the slopes at risks. VULNERABILITY ADJUSTMENTS Community Preparedness The most formal arrangements for mass movement hazards exist in slide prone areas where a variety of organization which often exists to reduce the risk. There is a vital need to prepare the community regarding the landslides. There is a need for a locally based, rapid response search and rescue team and this is crucial because the debris flow victims die quickly if buried beneath the debris. Thus the chances of survival decline rapidly after 1-3 hours, even when the victim is trapped closed to the surface. The overall survival rate after complete burial is less than 2 in 5. Therefore, local communities should be aware and they should have the rescue trainings and the right tools, which should be provided by the local government absolutely free or on the subsidy, to rescue the life of the victims.

This process can be monitored with a view to providing a warning. The most common forms of monitoring include the use of inclinometers and telemeters to record evidences of increased hill slope activity but this information is rarely formalized into official warning messages. For landslides it is possible to issue generalized regional warnings of debris and mudflows following storms and heavy rainfall based on some locally relevant threshold criteria, such as storm rainfall intensity per hour or the cumulative total of rain over a few days. For example a real time regional landslide warning system was developed for the San Francisco region using known relations between rainfall and landslide generation and tele-metered rainfall data in association with weather forecasts (Keefer et. al., 1987). It was used to issue the first regional, public landslide warnings in USA in February 1986, but the site-specific prediction of landslide remains elusive. Therefore prediction also plays the vital role in the management of the landslide because after the prediction of rainfall or landslide people prepare themselves for the hazard and reduce the vulnerability of the disaster.

Landslide Disasters and its Management

The recurrence of many landslides and avalanches at the same topographic site means that land use zoning offers a practical method of hazard mitigation. The qualitative recognition of sites susceptible to multiple mass movements is often possible. For example, many avalanche tracks also function as landslide gullies during the summer and spring. Stream channels are the most common paths for debris flows, which occur after periods of heavy rain. Although different from floods, debris flows can aggravate flood conditions by blocking the channel and causing water to overspill the banks. For landslides, geologists or geo-technical engineers can make a stability assessment for individual sites. Keaton (1994) described a probabilistic approach to site selection. This depends on geological investigations to determine the magnitude frequency of relationships in potentially hazardous processes combined with estimates of the probability that damaging events would occur during a specified exposure period, such as the anticipated life of a structure. The development of information technology with the issue of a GIS database and spreadsheet calculations makes such approaches increasingly feasible.

tectonic shear zones and slope aspect. Geological hazard zoning maps at a scale around 1:20,000 are still the most common form of hazard identification. Seeley and West (1990) provided an example for a forest park in the western USA where slope instability, including seismically included rock falls and avalanches, is the most important hazard. Once the hazard has been identified, planning law should explicitly encourage local communities to consider mass movement processes when undertaking the landuse changes. Avalanche zoning employs historical data of avalanche occurrence for the identification of hazardous locations and supplements this information with terrain models and models of avalanche dynamics to determine more detailed degrees of risk. Where sites are near established settlements, avalanche frequency will be a matter of local knowledge. At more remote locations, with insufficient records and maps, other methods are necessary. Gruber and Haefner (1995) have reported the developing use of satellite imagery and digital elevator models to map large areas of avalanche risk. Sometimes the long term pattern of avalanche activity can be compiled from trees which remain standing in the track or run out zone but which have been physically damaged by previous events. Sometimes the resulting scarring of tree rings can provide an accurate means of dating avalanches of landslides and producing reliable frequency estimates over the past 200 years or so (Hupp et. al., 1987). Where trees have been destroyed by large events, close inspection of the residual damaged vegetation, including height and species can be a useful guide. Once potential sites have been identified and frequency estimates made, initial mapping is usually undertaken at a scale of about 1: 50,000 with the aid of air photographs. In India, a snow avalanche atlas is published primarily as an operational guide for highway maintenance personnel (Ministry of Transportation and Highways, 1991). The maps are accompanied by a detailed description of terrain and vegetation for each avalanche site, together with an assessment of the hazard impact. The same kind of hazard and risk zone mapping work has been successfully done by the National Agency of Thematic Mapping Organization (NATMO) India. In this atlas they specifically divided all kind of hazards into several categories and zones, particularly the seismic map which helps to know about the seismic zone category. It indicates the importance of a map because it is more useful for each and every planner in constructing or planning any kind of structural change in landuse. Where an avalanche threatens settlements, it is necessary to zone the area on a larger map scale which may be of 1:50,000 and adopted related planning regulations. The length of the debris flows zone is a critical factor here since it determines whether or not a particular site will be reached by the movement of rocks and debris. The zoning methodology is well established in many countries.

waiting for government support, should handle work. The government should provide the rescue kit absolutely free of cost, which contains all the equipment, that is required at the time of landslides and debris flows. The government should provide this kit along with the training programmes, which should be organized at all levels like school, college, university level. And all the government and private employees should get this training free of cost and the rescue kit also. This program should be launched on the basis of hazard zonation maps and the degree of vulnerability of the locality. Overall “prevention is better than cure”. REFERENCES Alexander, D.

waiting for government support, should handle work. The government should provide the rescue kit absolutely free of cost, which contains all the equipment, that is required at the time of landslides and debris flows. The government should provide this kit along with the training programmes, which should be organized at all levels like school, college, university level. And all the government and private employees should get this training free of cost and the rescue kit also. This program should be launched on the basis of hazard zonation maps and the degree of vulnerability of the locality. Overall “prevention is better than cure”. REFERENCES Alexander, D.

Flood Disaster: Its Impact, Challenges and Management in India Rajesh Kumar Abhay Senior Research Scholar, Department of Geography, Delhi School of Economics University of Delhi, Delhi-110007, India

INTRODUCTION Flood is the most destructive natural disaster which extensively damages the life and property in India. It is very difficult to predict flood, because of its nature. It may be rightly stated that such types of natural calamities leave behind a story of death, hunger, epidemic and mass destruction. Flood is a natural phenomenon, whose roots are in monsoonal rainfall. It means that it is the result of over rainfall. Of the total annual rainfall in the country, 75 per cent is concentrated over a short monsoon season of three to four months. As a result, there is a large amount of discharge from the rivers during the monsoon period causing floods. Flood hazards are precisely called natural since they are the result from a set of natural phenomena, connected directly with the atmosphere and surviving topographical structure. It has been seen in India that most parts of north-eastern India are more frequently hit by the severe floods. This entire region is ecologically fragile with respect to flood because of the large river system of the country with its hundreds of tributaries. Floods are increasing in India with respect to intensity, magnitude and frequency. If we plot the data of floods on a hydrograph, it will be quite clear to us that the intensity of floods is increasing every year and they are caused by a large number of managerial problems in the country. Floods in India India is the most flood affected nation in the world after Bangladesh. It accounts

Flood is the most destructive natural disaster which extensively damages the life and property in India. It is very difficult to predict flood, because of its nature. It may be rightly stated that such types of natural calamities leave behind a story of death, hunger, epidemic and mass destruction. Flood is a natural phenomenon, whose roots are in monsoonal rainfall. It means that it is the result of over rainfall. Of the total annual rainfall in the country, 75 per cent is concentrated over a short monsoon season of three to four months. As a result, there is a large amount of discharge from the rivers during the monsoon period causing floods. Flood hazards are precisely called natural since they are the result from a set of natural phenomena, connected directly with the atmosphere and surviving topographical structure. It has been seen in India that most parts of north-eastern India are more frequently hit by the severe floods. This entire region is ecologically fragile with respect to flood because of the large river system of the country with its hundreds of tributaries. Floods are increasing in India with respect to intensity, magnitude and frequency. If we plot the data of floods on a hydrograph, it will be quite clear to us that the intensity of floods is increasing every year and they are caused by a large number of managerial problems in the country.

for one-fifth (1/5) of global deaths due to floods and on an average thirty million people are evacuated every year. So floods in India are not a new phenomenon. “Unprecedented floods” take place every year in one state or another of the country. India has been traditionally affected by flood. The vulnerability of the states of India due to floods was not observed severely in the past due to low developmental activities and lack of population interest. However, in the present time, modern population and the high rate of developmental activities has forced of houses the occupation on flood plains and this makes the society highly vulnerable to flood losses. India is one of the richest countries in the world with regard to its water resources and it is continuously affected by this natural resource in the form of floods. India receives 75 per cent of its total annual rainfall in just 100 hours of four months of the rainy season (monsoon). In monsoon seasons, all rivers flow with large amounts of water. These rivers bring floods to the plain areas because of the low slopes and the fast flow of the water. In the last few decades in India the magnitude and the intensity of flood occurrence has increased tremendously. According to the CSE (Centre for Science and Environment), in the present time floods are not only a research issue but have now become a critical topic to think about for the environmentalist, Hydrologist, Geographers and for other disciplines also. Now the need for proper management of water has been felt due to the floods. In India, 22 states and one Union territory (Andaman & Nicobar) are vulnerable to Floods. However, the most vulnerable states of India are Uttar Pradesh, Bihar, Assam, West Bengal, Gujarat, Orissa, Andhra Pradesh, Madhya Pradesh, Maharashtra, Punjab and Jammu & Kashmir. In a district wise in 1991, there were 137 districts which were vulnerable to floods (Fig. 1).

Types of Floods

Flash Floods: Such floods occur within six hours during heavy rainfall and usually are associated with towering cumulus clouds, severe thunderstorms, tropical cyclones or during the passage of cold weather fronts. This type of flooding requires rapid localized warnings and immediate response by affected communities. Other causes of flash floods include Dam failure or other river obstructions. River Floods: Such floods are caused by precipitation over large catchment areas or by the melting of snow or sometimes both. They take place in river systems with tributaries that may cover or drain large geographical areas and encompass many independent river basins. These floods normally build up slowly or seasonally and may continue for days or weeks as compared with flash floods. Factors like ground conditions like moisture, vegetation cover, depth of snow etc. and the size of the catchment basin govern the amount of flooding. e.g. Main rivers of India like Ganga, Brahmaputra and Yamuna etc. Coastal Floods: Some floods are associated with the cyclonic activities like

Effects of Floods Precisely, the flood hazards have the following impacts on the various anthropogenic activities including two major sectors i.e. agriculture and socioeconomic conditions of society: 1. Every year millions of people become homeless, rendered for shelter for many days and force to stay under the open sky. 2. Millions of houses and settlements have been damaged and large number of them collapsed. 3. Hundreds of people fled away in the flood water and equally numbers have been died either due to lack of food availability or epidemics. 4. Millions hectares of agricultural land come under the deep flood water and not in the condition for further cultivation. 5. Millions of tonnes of fertile top soil have been eroded by several major rivers and their tributaries in the country and ultimately they have been deposited in the sea. 6. Thousands of hectares of land have been converted into waste land/barren land resulting in problems where a lot of salinity and alkalinity including water logging, originate. 7. Production of certain agricultural crops including cash crops are either drastically gone down or have lost their quality and quantity. 8. Due to the standing of large quantities of flood water at certain places for long time, various types of water borne diseases and groundwater table, suddenly rise up. 9. Thousands of livestock have either fled away in flood water or have died in the wake of a fodder shortage. 10. Landslides followed by incessant rains during floods are a very common phenomena. Flood-producing rains can trigger catastrophic debris slides. 11. National and state highways including other associated link roads have been submerged in flood water. Consequently the failure of traffic for several weeks or so results in a heavy disruption of economic and commercial activities. 12. Due to the submergence of railway tracks in flood water in several rail route sections, rail services are either cancelled or badly disrupted and the result is that villages remain cut-off from the main land until the flood subsides. 13. The power supply has been totally damaged both with water and electricity because almost all electric poles are at times uprooted, especially in coastal areas by the speedy winds accompanied by heavy rains. 14.

Disaster Relief Flood fighting including Public Health Measures

The setting up of flood forecasting and warning services is one of the most cost-effective non- structural measures available. Flood Plain Management and Zoning The basic concept is to regulate the land use in flood plain zoning in order to restrict the damage potential due to floods. The Rashtriya Barh Ayog (1980) & Central Water Commission (CWC) recommended that flood plain management measures should be undertaken and suitable management legislation enacted. This zoning is done by determining the locations and the extent of areas which are affected by floods of different magnitudes or frequencies and then to develop such areas where the damage is minimum in case floods do occur. Therefore, Flood Plain Zoning aims to regulate the indiscriminate and unplanned development in flood plains. It is relevant both for unprotected as well as protected areas. It recognizes the basic fact that the flood plains are essentially the domain of the river, and as such all developmental activities in flood plains must be compatible with the flood risk involved. Flood Proofing Such measures help greatly in the management of disasters for the population in flood prone areas. It is essentially a combination of structural change and emergency action without evacuation. A programme for flood proofing provides the raised platforms for flood shelters for men and cattle and raising the public utility installations above flood levels. Under this programme, several villages were raised in Uttar Pradesh. In West Bengal and Assam, land fills were attempted in villages to keep houses above flood level in some areas. In the Eighth Plan (1992-97), the flood proofing programme was proposed for the Ganga basin states, particularly for the North Bihar areas.

Flood disasters are natural so we cannot control floods completely, but with the help of management techniques, preparedness and spreading awareness among the people, we can reduce the impact of flood disaster. So we can say that flood management is more effective than flood control. Thus for its management, the integrated approach is the key tool for effective planning and action in all parts of Disaster Management. Local knowledge should be integrated with

It has several advantages as a means for modifying the loss burden, although it is being provided to cover the ‘Flood Risk’ yet on a limited and selective scale. This is mainly because of the intricacy in the matter of fixing a premium and the possibility of a payment of claims is frequent in acutely flood prone areas. The Ministry of Agriculture has initiated a pilot scheme for crop insurance in flood affected areas. Of all the non-structural measurers for flood management, the one which is gaining the attention of the planners and acceptance by the public is the flood forecasting and warning system. Other measurers, especially the flood plain zoning, have to be tackled with more energetically so that a long term solution to flood problems can be achieved in conjunction with structural measures wherever necessary.

Flood disasters are natural so we cannot control floods completely, but with the help of management techniques, preparedness and spreading awareness among the people, we can reduce the impact of flood disaster. So we can say that flood management is more effective than flood control. Thus for its management, the integrated approach is the key tool for effective planning and action in all parts of Disaster Management. Local knowledge should be integrated with

existing scientific knowledge to produce more realistic, locally appropriate and more effective disaster preparedness activities. In India, it has been observed that most parts of the country, especially northern India, are severely affected by flood hazards particularly the IndoGangetic-Brahmaputra plain. Almost all the anthropogenic and commercial activities are badly hampered on a large scale by the flood hazards during the last 4-5 decades subsequently there has been a destabilization of the Indian economy. So, in order to mitigate flood hazards, there is an urgent need first of all to identify and map flood prone areas. Secondly, the new modern techniques should be applied for an advance warning system which is possible now through various satellite and Remote Sensing services. Hence, the flood forecasting and warning systems should be adopted because they are one of the most reliable and cost effective methods and moreover, over the years there is a considerable improvement in the methodology and acquisition of the latest technology. Dams, embankments and reservoirs should be launched involving local people especially the women along the rivers, streams and canals. The women can clean drains and strengthen their embankments and similarly clean up driveways. A system should also be launched in order to remove the deposited debris and silt in all the vulnerable rivers, canals and drains in the presence of expert engineers right before the occurrence of the monsoon season. By adopting all these said measures and flood management works in the country, it would be possible to save the precious lives of human-beings including cattle wealth and considerably reduce the immense flood damage to the country.

INTRODUCTION At the present time, the challenges and opportunities for reducing loss from environmental hazards has never been greater. Theoretically, the challenge is easily defined; but to eliminate all disasters, which cause death and injury or damage to property or the environment is impossible to achieve. Although many risks are potentially avoidable, global environmental change and uncertainty about future hazardous events, together with the central role played by human failings in all disasters, makes the total elimination of hazards an unrealistic task. The question then is How safe is enough? As Charlton (1990) suggests, this question is a little like asking an athlete: How fast is enough? All he or she can answer is: As fast as I can run today and then faster still tomorrow.’ The existing databases are inadequate for the precise determination of spatial and temporal patterns of disaster worldwide but available evidence suggests that the overall losses remain high. Despite increased investments in hazard mitigation measures, deaths and material damage shows few signs of a sustained decline. The continued growth of population and the encroachment of humans into hazardous zones plus the rise in exposed wealth resulting from economic growth are the main causes. The greatest absolute financial losses continue to occur in the MDCs whilst Third World countries experience the most severe impacts, in terms of death and relative economic loss. In some cases these impacts are sufficiently severe to jeopardize economic and developmental efforts.

that the toll exerted by disasters, especially in the LDCs, is unacceptable. It is defeatist not to bring hazard awareness into development planning because continuing disaster losses simply reinforce poverty and vulnerability. Disaster impact in the Third World needs to be reduced to the point where stable investment can take place and the indigenous skills and energy, on which sustainable long term development depends, can be released. It seems likely that, following the International Decade for Natural Disaster Reduction (IDNDR) of 1990-2000, environmental hazards will remain high on the public policy and political agenda for some time to come. Nature of Problem According to Anderson (1991), loss reduction is a less costly alternative than disaster recovery and this strategy is widely adopted in the MDCs. Extending disaster reduction to the LDCs will provide more difficulty, especially when mitigation is required for disasters such as drought, that cover large areas and involve severe environmental degradation. Loss reduction can be achieved either by modifying the hazard events itself or by reducing its human impact. These approaches are not mutually exclusive and they often work best in some combination, which may also include a loss sharing measure, such as insurance. The aim of physical event modification is to reduce the damage potential associated with a particular hazard by exerting some degree of physical control over the process involved. Total control, whereby the dangerous release of energy or materials is either suppressed or diffused at lower intensities into the environment, is impossible given the present state of knowledge. However, certain natural threats can be modified by specially engineered structures, which provide some protection by buffeting individual buildings or limited high-hazard zones, such as part of a river floodplain, against events of special magnitudes. This approach is sometime called ‘hazard-proofing:’ which is an unsuitable term because it implies a total level of security that can hardly ever be offered. A better phrase is hazard resistance. Hazard resistance involves more than engineering science. It is operated through building codes and other regulations, which imply a high degree of community acceptance and support. To this extent hazard resistance lies at the interface between loss reduction measures based on adjusting events to people and those based on adjusting people to events. The crucial difference is that event modification relies to some degree on hazard confrontation involving physical protection whereas human vulnerability modification relies on hazard avoidance involving mainly non-structural responses. Table 1 below indicates that: • Between 1991 and 2000, Asia was the continent the most frequently hit by disasters, registering 43 percent of the total numbers of event recorded in EMDAT. • Middle developing countries accounts 60 percent of the total events.

that the toll exerted by disasters, especially in the LDCs, is unacceptable. It is defeatist not to bring hazard awareness into development planning because continuing disaster losses simply reinforce poverty and vulnerability. Disaster impact in the Third World needs to be reduced to the point where stable investment can take place and the indigenous skills and energy, on which sustainable long term development depends, can be released. It seems likely that, following the International Decade for Natural Disaster Reduction (IDNDR) of 1990-2000, environmental hazards will remain high on the public policy and political agenda for some time to come.

In the case of earthquakes, hazard resistance begins with geo-technical engineers, who apply the principles of rock and soil mechanics to the safe design of earth supported structures. Other things being equal, buildings on solid rocks are less likely to suffer damage than those built on clays or softer foundations. Smallscale maps of the sub state can be prepared which suggest local variations in building strength and ensure that major buildings are not located over faults or areas of un-consolidated material. Local building codes tend to undergo Continent

The potential scales of human intervention with natural hazards can be illustrated with reference to floods. Theoretically, large-scale environmental control can be attempted through either weather modification or watershed treatment. The aim is either to stop flood-producing rains by cloud seeding, or to reduce flood flows by conservation measures such as afforestation or contour cultivation over large areas of the drainage basin. On the other hand, hazard resistance design would involve building structures such as dams to store the floodwater in the upper part of the basin or embankments to contain the flood flows further downstream. At the smallest scale, hazard resistance design can apply to individual buildings through structural adaptations, such as raising the floor level, that make them and their contents less susceptible to flooding. However, there is little evidence that floods can be fully controlled over large drainage basins by any of these adjustments (Smith and Ward, 1998). Hazard resistance occurs when engineered buildings are erected in compliance with local building codes. A building code is intended to ensure that building is located, designed and constructed so that, if it is objected to specified destructive forces of either natural or man made origin, it will present no threats either to its occupants or to the general public. For example, the Uniform Building Code /Norms, which updated annually in the USA and also in India, contain a map of six seismic zones based on ground motions and recorded damage from previous earthquakes. The higher the apparent risk, the more stringent the building regulations, and many buildings can also be retrospectively strengthened to withstand loads more safely. In most countries, public facilities such as dams, bridges and pipelines are likely to be hazard- resistant because professional engineers have designed them. The same is true for large industrial structures such as nuclear power plants and chemical factories. However, design protection can never be totally perfect. Building failure will be greatest in data-poor, hazard-prone environments where many structures – older buildings and small rural houses, will have been constructed without any thought to hazard impact. The two most common natural hazards considered in building codes are earthquakes and windstorms, although the adjustment is also applicable to other hazards such as floods.

In the case of earthquakes, hazard resistance begins with geo-technical engineers, who apply the principles of rock and soil mechanics to the safe design of earth supported structures. Other things being equal, buildings on solid rocks are less likely to suffer damage than those built on clays or softer foundations. Smallscale maps of the sub state can be prepared which suggest local variations in building strength and ensure that major buildings are not located over faults or areas of un-consolidated material.

Disaster Management

The potential scales of human intervention with natural hazards can be illustrated with reference to floods. Theoretically, large-scale environmental control can be attempted through either weather modification or watershed treatment. The aim is either to stop flood-producing rains by cloud seeding, or to reduce flood flows by conservation measures such as afforestation or contour cultivation over large areas of the drainage basin. On the other hand, hazard resistance design would involve building structures such as dams to store the floodwater in the upper part of the basin or embankments to contain the flood flows further downstream. At the smallest scale, hazard resistance design can apply to individual buildings through structural adaptations, such as raising the floor level, that make them and their contents less susceptible to flooding. However, there is little evidence that floods can be fully controlled over large drainage basins by any of these adjustments (Smith and Ward, 1998). Hazard resistance occurs when engineered buildings are erected in compliance with local building codes. A building code is intended to ensure that building is located, designed and constructed so that, if it is objected to specified destructive forces of either natural or man made origin, it will present no threats either to its occupants or to the general public. For example, the Uniform Building Code /Norms, which updated annually in the USA and also in India, contain a map of six seismic zones based on ground motions and recorded damage from previous earthquakes. The higher the apparent risk, the more stringent the building regulations, and many buildings can also be retrospectively strengthened to withstand loads more safely. In most countries, public facilities such as dams, bridges and pipelines are likely to be hazard- resistant because professional engineers have designed them. The same is true for large industrial structures such as nuclear power plants and chemical factories. However, design protection can never be totally perfect. Building failure will be greatest in data-poor, hazard-prone environments where many structures – older buildings and small rural houses, will have been constructed without any thought to hazard impact. The two most common natural hazards considered in building codes are earthquakes and windstorms, although the adjustment is also applicable to other hazards such as floods.

The potential scales of human intervention with natural hazards can be illustrated with reference to floods. Theoretically, large-scale environmental control can be attempted through either weather modification or watershed treatment. The aim is either to stop flood-producing rains by cloud seeding, or to reduce flood flows by conservation measures such as afforestation or contour cultivation over large areas of the drainage basin. On the other hand, hazard resistance design would involve building structures such as dams to store the floodwater in the upper part of the basin or embankments to contain the flood flows further downstream. At the smallest scale, hazard resistance design can apply to individual buildings through structural adaptations, such as raising the floor level, that make them and their contents less susceptible to flooding. However, there is little evidence that floods can be fully controlled over large drainage basins by any of these adjustments (Smith and Ward, 1998). Hazard resistance occurs when engineered buildings are erected in compliance with local building codes. A building code is intended to ensure that building is located, designed and constructed so that, if it is objected to specified destructive forces of either natural or man made origin, it will present no threats either to its occupants or to the general public. For example, the Uniform Building Code /Norms, which updated annually in the USA and also in India, contain a map of six seismic zones based on ground motions and recorded damage from previous earthquakes. The higher the apparent risk, the more stringent the building regulations, and many buildings can also be retrospectively strengthened to withstand loads more safely. In most countries, public facilities such as dams, bridges and pipelines are likely to be hazard- resistant because professional engineers have designed them. The same is true for large industrial structures such as nuclear power plants and chemical factories. However, design protection can never be totally perfect. Building failure will be greatest in data-poor, hazard-prone environments where many structures – older buildings and small rural houses, will have been constructed without any thought to hazard impact. The two most common natural hazards considered in building codes are earthquakes and windstorms, although the adjustment is also applicable to other hazards such as floods.

METHODS TO BE ADOPTED FOR HAZARD REDUCTION 1. Hazard Resistance Design In the case of earthquakes, hazard resistance begins with geo-technical engineers, who apply the principles of rock and soil mechanics to the safe design of earth supported structures. Other things being equal, buildings on solid rocks are less likely to suffer damage than those built on clays or softer foundations. Smallscale maps of the sub state can be prepared which suggest local variations in building strength and ensure that major buildings are not located over faults or areas of un-consolidated material. Local building codes tend to undergo

continuous improvement and the adaptation and enforcement of such improvements is the primary means of increasing the hazard resistance of structures through time. Today, virtually all-building failure under hazard stress can be explained with existing knowledge. This is not to say that engineered structures will never be damaged, because building codes establish minimum standards and rarely specify the maximum possible loads. Instead, they provide against the intensity of hazard events, which are considered to have a reasonable chance of occurring during the lifetime of the structure. If an event of a greater magnitude than the design standards occurs, then the structure can be expected to fail to some extent. For wind loading codes, common in areas subject to tropical cyclones, design velocities are given for various return periods. Most of the problems arise because of the lack of the strict enforcement of building codes and the quality of on-site construction can rarely be guaranteed. This is a special difficulty in the LDCs, where a lack of technical expertise and other resources commonly produce a failure to meet the design requirements. The problem also exists in the MDCs and it has been suggested that the cost of the 1994 Northridge earthquake in California, estimated at over 20 billion US dollars, might have been halved if all the damaged buildings had been built to the appropriate norms (Valery, 1995). Some buildings may have to withstand events that occur after decades without threat. Rather than construct a new, earthquake-resistant building at high capital cost, owners tend to refurbish the interior many times to keep pace with changing uses. Thus, the structure may have to endure far beyond a theoretical life. It follows that inventories should be available in all hazard-prone areas of the engineering status of the built environment. Hazard resistant design has had rather limited success in the past. One reason has been the priority given to the functional requirement of building during disaster events. Most attention has been paid to public buildings and facilities which are expected to remain operative during emergencies (hospitals, police stations, pipelines etc.) and those which are expected to remain intact in order to house essential items (certain computer centers, warehouses holding emergency supplies). Other public buildings, such as schools, offices and factories, have sometimes been strengthened in the belief that they will shelter large numbers of people seeking refuge. On the other hand, government premises have sometimes been exempted from building code/norms. In comparison, little attention has been given to privately owned residential buildings. The consequences of the selective application of building codes may be demonstrated by tropical cyclone ‘Tracy’, which struck Darwin, northern Australia, in 1974. This event caused structural collapse in only 3 percent of the engineered buildings that had been constructed to wind resistant codes over the previous 20 years. In contrast, some 5,000 out of 9,000 un-engineered houses (50-60 percent) were physically destroyed beyond repair, with the result that three-quarters of the population had to be evacuated (Stark and Walker, 1979). In this rapidly developing area, the construction of new, low-rise housing had

been based on building traditions inappropriate for a cyclone prone settlement. The Darwin disaster prompted a radical review of policy in Australia. It is now accepted that, typically, residential housing accounts for about half the total value of buildings in the community and therefore, equal economic importance to the public buildings previously, is now regarded as more significant. Experience has also shown that, when cyclone warnings are issued, most public buildings close down and the vast majority of the local population seek shelter in their own homes. The general conclusion is that greater attention should be paid to cyclone resistant design in the residential sector. However, private property owners are reluctant to pay for strengthening their homes against natural hazards if they believe that any losses will be compensated by insurance or government assistance. In addition, local authorities may resist the introduction of building codes if they feel that the cost of compliance and inspection will hamper economic development. But, as commercial insurance against natural disasters becomes harder to obtain, and as taxpayers increasingly rebel against property owners who take no anti-hazard actions, hazard resistance design is likely to become more important. Faced with rising costs, insurers and governments are requiring owners to adapt a more responsible attitude and are becoming less willing to provide routine compensation for poorly constructed and maintained buildings. Indeed, if taken to its theoretical limit, proper hazard-resistant design could make structural property insurance and related disaster funds largely irrelevant. 2. Retrofitting Another limitation exists when hazard-resistant design is restricted to new properties. Because of this, retrofitting – the act of modifying an existing building to protect it from a damaging event, is an important issue. Many individual measures can be taken. In the case of earthquakes, for example, brick chimneys can be reinforced and braced onto structural elements to prevent collapse into a living area. Un-reinforced masonry walls can be strengthened and tied to adequate footings, while closets and heavy furniture can be strapped to the walls whenever they constitute a danger or contain vulnerable items. To protect against floods, measures include making the wall water tight and fitting flood resistant doors and windows. Retrofit measures are useful in that they are often quicker to install than some other hazard responses. On the other hand, doubts have been expressed about the economic viability of retrofitting. Hundreds of Japanese schools and hospitals have been strengthened for seismic resistance at a cost of up to 50-80 percent of that for new buildings. Such resources are unlikely to be put into the private sector. For residential property the alternative to retrofitting is to let the occupants of older houses remain at risk until the building deteriorates to a point where the owner or a developer sees some economic incentives to replace the structure at a higher standard.

Disaster Management

Retrofit laws passed by local authorities require the identification and strengthening (or demolition) of existing hazardous buildings but the social, economical and political issues involved can make the approach difficult to implement. It has been estimated that a retrofit policy in India and Japan would substantially reduce the potential hazard to life, with perhaps a five fold reduction in casualties from earthquakes. However, one disadvantage of the retrofit ordinance adopted in 1981 was that some of the city’s lowest priced housing would be demolished; tenants would have to be relocated while remedial work was carried out and there would be considerable disruption to small business activity. Special provisions also had to be introduced to ensure that some unsafe buildings of historical significance were preserved. An attractive feature of retrofitting is that most of the government’s construction and maintenance costs are borne by the property owner, although little official encouragement has been given. One reason for the relative underemployment of retrofitting is that many government agencies are unable to spend any public funds for the direct improvement of private property. Furthermore, it is difficult to disseminate information about measures, which may not be appropriate for all buildings, in terms that are both understandable to the home owner yet sufficiently technical to insure that the best method will be chosen and correctly installed. In these circumstances, it will be that there is a case for more government commitment to retrofitting. With more technical and financial assistance, hazard-conscious property owners could be helped to help themselves to a far greater extent. 3. Society Attentiveness Disaster attentiveness may be defined as the pre-arranged emergency measures taken to minimize the loss of life and property damage following the onset of a disaster. It involves the detailed planning – and testing – of the prompt and efficient responses to hazard threats. Once a threat has been identified, various groups of people and officials, representing many different interests, become involved in the assembly and transfer of relevant information. Appropriate loss reducing measures, depending on the nature of the hazard, may include the activation of evacuation plans (often in response to an expected warning message), the provision of medical aid and the preparation of emergency food and shelter, together with alerting the media and the public of the impending threat. Long–term programmes have proved successful in reducing deaths from hazards. Within individual countries, the degree of attentiveness usually depends on the arrangements, which have been made for civil defense. For example, in the mission of Emergency preparedness, Canada ensures that the emergency plans of the government of Canada are in place and are ready to protect life and property.

The volcanic emergency plan for Rabaul, Papua New Guinea, which was prepared under the guidance of UNDRO in the 1980s, was largely responsible for the effective evacuation and low loss of life when major eruptions occurred in 1994. Evacuation away from hazard zones is generally effective in saving lives. The evacuation map prepared for the city of Salinas, which is situated on a low, narrow peninsula on the coast of Ecuador (UNDRO, 1990) on the western coast of south America, is one of the most seismically active zones on earth and much of the city is only a few metres above sea level and vulnerable to tsunami flooding either from the north or the south. If a tsunami is generated locally, the evacuation time before the arrival of the first tidal wave is likely to be only 20-25 minutes so routes to the higher refuge area have to be well organized and understood. For those people unable to reach this area – the ill, the elderly and small children – several tall seismically resistant buildings will be used as refuges for vertical migration.

much better prepared. Most of the people surveyed had stockpiled supplies, whist the proportion of those who took very specific steps, such as strapping water heaters to walls, bolting the house to the foundations and installing flexible piping to gas stoves, were encouragingly high given that many bay area residents live in apartments without individual water heaters or accessible foundations and cook on electric stoves (Militia and Darlington, 1995). Good educational programmes are necessary to ensure that widespread public support is available for hazard mitigation and that disaster experience is transferred from one society to another. Conceived awareness exercises may create panic so it is important that such programmers are suitably found in terms of social feasibility and have an understanding of the probable economical consequences of the mitigation measures recommended to the public. Recent experience suggests that carefully prepared advice needs to be distributed, both widely and often to the public through the media and other channels. All prepared-ness advice should come from an authoritative government agency and should be endorsed by well-known local officials and pubic figures. Each measure should be accompanied with a brief explanation, which justifies the recommended action and details of how it can best be implemented. Although community preparedness may appear a little more than applied common sense, there are many pitfalls, which prevent a less than adequate response. For example, once awareness begins to increase and people actively start to seek information; the responsible agencies may find it difficult to meet the demands for written material or for speakers to attend public meetings. Effective preparedness involves the home as well as public locations, such as schools, hospitals, offices and theatres. Pubic bodies and private sector corporations often have an opportunity to build awareness of environmental hazards into existing health and safety programmers but it is difficult to monitor the status of such initiatives within the home. This is rarely attempted, not least because of the resource implications. Over twenty years ago, Stratton (1979) emphasized the need to learn from past disasters. There was little attentiveness in drawing for the 1974 storm in which 65 lives were lost and most houses were rendered uninhabitable. The absence of local emergency shelters and the high risk of disease in this tropical environment led to the evacuation of 35,000 people and major problems, which have also been found in other disasters, included the breakdown of the normal communication systems, disputes between various emergency and relief organizations over priorities and responsibilities, lack of coordination in the distribution of relief goods and an under availability of trained medical and ambulance personnel. These difficulties can be reduced by pre-designating centralized control of the relief operation. It should also be recognized that basic services such as roads, water supplies or telephones, are unlikely to be fully available and a wider practical knowledge of appropriate self-help techniques-such as first aid, search and rescue and fire-fighting–should be promoted within communities at risk, as this type of team in India is known by

the Civil Defence and Home Gourd’s squads. During the Civil Defence and Home Gourd training programme, practical knowledge of appropriate self-help techniques-such as first aid, search and rescue and fire-fighting etc. are been introduced to the defence cadets. 4. Worldwide Attentiveness One of the main challenges in disaster prevention is to implement effective attentiveness schemes in the developing nations through a sensitive understanding of the different socio-cultural settings which prevail and the leading responsibility for this is taken by UNDRO in Geneva, supported by a variety of government agencies and NGOs. For example, in Britain, the Overseas Development Administration (ODA) has maintained a Disaster Unit since 1974, which offers government aid for both natural and man-made disasters in the LDC s and for natural disasters in the MDCs. Several countries maintain specialist rescue and relief groups pledged to UNDRO who can be provided with equipment and transport when disaster strikes. For example, Oxford maintains an emergency store with cooking equipment and material for constructing temporary shelters. The success of such arrangements depends on UNDRO acting as an effective link between the donors and recipients of aid. UNDRO needs to maintain a register of available expertise and also needs specific information form the victim nation about exactly what aid is required in order to avoid mismatched donations. Regular regional training programmers are held for the staff involved at designated Disaster Preparedness Centres worldwide. Much disaster planning is based on military lines. This stems from a view that disaster relief is similar to running a battle, and great stress is laid on aspects such as communications, logistics and security. These are clearly important requirements but the ‘command and control’ model, represented by a topdown, rigidly controlled organization, is not always appropriate, especially for the LDCs. External military forces may be seen as enacting foreign policy on behalf of distant ‘colonial’ powers, giving the dangers of a confrontation with either the national government or aid agencies striving to be neutral. Poor people are often suspicious of military forces, which may not be completely sensitive in operating refugee camps or dealing with women and children. On the other hand, specialized forms of military assistance – such as airlifted relief supplies – can be of great value. This happened, for example, when in April 1991 the US Defence Department deployed assets positioned in the Indian Ocean at the time of the Gulf War to transport relief supplies, repair damaged roads and provide purified water for cyclone victims in Bangladesh. One of the traditional deficiencies of military support has been that it was inevitably shortlived because it was diverted from ongoing defence duties. It would be an imaginative step if disaster relief work became a more permanent function of western military capability, but, without formal training in relief work, the best role for the armed services is still likely to be in a support capacity for the civil authority or the NGOs.

During the Civil Defence and Home Gourd training programme, practical knowledge of appropriate self-help techniques-such as first aid, search and rescue and fire-fighting etc. are been introduced to the defence cadets. 4. Worldwide Attentiveness One of the main challenges in disaster prevention is to implement effective attentiveness schemes in the developing nations through a sensitive understanding of the different socio-cultural settings which prevail and the leading responsibility for this is taken by UNDRO in Geneva, supported by a variety of government agencies and NGOs. For example, in Britain, the Overseas Development Administration (ODA) has maintained a Disaster Unit since 1974, which offers government aid for both natural and man-made disasters in the LDC s and for natural disasters in the MDCs. Several countries maintain specialist rescue and relief groups pledged to UNDRO who can be provided with equipment and transport when disaster strikes. For example, Oxford maintains an emergency store with cooking equipment and material for constructing temporary shelters. The success of such arrangements depends on UNDRO acting as an effective link between the donors and recipients of aid. UNDRO needs to maintain a register of available expertise and also needs specific information form the victim nation about exactly what aid is required in order to avoid mismatched donations. Regular regional training programmers are held for the staff involved at designated Disaster Preparedness Centres worldwide. Much disaster planning is based on military lines. This stems from a view that disaster relief is similar to running a battle, and great stress is laid on aspects such as communications, logistics and security. These are clearly important requirements but the ‘command and control’ model, represented by a topdown, rigidly controlled organization, is not always appropriate, especially for the LDCs. External military forces may be seen as enacting foreign policy on behalf of distant ‘colonial’ powers, giving the dangers of a confrontation with either the national government or aid agencies striving to be neutral. Poor people are often suspicious of military forces, which may not be completely sensitive in operating refugee camps or dealing with women and children. On the other hand, specialized forms of military assistance – such as airlifted relief supplies – can be of great value. This happened, for example, when in April 1991 the US Defence Department deployed assets positioned in the Indian Ocean at the time of the Gulf War to transport relief supplies, repair damaged roads and provide purified water for cyclone victims in Bangladesh. One of the traditional deficiencies of military support has been that it was inevitably shortlived because it was diverted from ongoing defence duties. It would be an imaginative step if disaster relief work became a more permanent function of western military capability, but, without formal training in relief work, the best role for the armed services is still likely to be in a support capacity for the civil authority or the NGOs.

Disaster Management

Beyond the technical aspects of delivering emergency aid, preparedness programmers should seek to encourage more local awareness of disaster prevention and relief. Local governments have the best access to the information needed to determine their own priorities and to manage their own environment. Workshops, pamphlets, brochures, videos and other materials are important tools to create high levels of knowledge among the threatened population. With a greater commitment to self-help and a greater reliance on local initiatives, preparedness plans could ensure a faster and more efficient reaction to disaster events, especially in the LDCs. 5. Forecasting and Warning Forecasting and warning systems (FWS) have become important due to scientific advances. For example, in weather forecasting, with the associated improvements in communications and information technology such as satellites. Most warnings of a future environmental hazard are based on forecasts but some threats, notably earthquakes and droughts, are insufficiently understood for forecasts to be routinely issued, so reliance on warnings has to be placed on prediction, forecasts and warnings. Predictions are largely based on statistical theory and use the historical record of past events to estimate the future probability of similar events. Because the results are often expressed in terms of average probability, there is no precise indication of when any particular event may occur. Some hazard predictions tend to be relatively long-term. For earthquakes they may extend to several decades ahead and it is not usually possible to specify the location or the magnitude of the event with much precision. Forecasts depend on the detection and evaluation of an individual event as it evolves through a sequence of reasonably well-understood environmental processes. The ease with which such individual events can be monitored is often possible because we can specify the timing, location and likely magnitude of an impending hazard strike. Forecasts are scientific statements and normally do not offer we can advice as to how people should respond. They tend to be short-term. Indeed, contrary to predictions, the limited leading in time for issuing forecasts often restricts the effectiveness of warnings. Warnings are messages, which advise the public at risk about an impending hazard and what steps should be taken to minimize losses. All warnings are based on weather predictions or forecasts but for many agencies, such as those involved with national weather services, very few of the routine forecasts are followed by warnings. Combined forecasting and warning systems (FWSs) are especially useful against the rapid-onset hazards where short-term action, often involving evacuation, can avert disaster. The greatest success has been achieved with atmospheric and hydrologic hazards to the extent that much of the reduced death toll from natural hazards in the MDCs can be attributed to improved

hurricane and flood warning procedures. On the other hand, some social changes – such as the growth of international tourism places increasing numbers of people at risk on hurricane-prone beaches, avalanche-prone ski slopes and floodprone riverbanks. Drabek (1995) suggested that the tourism industry is poorly prepared to meet this challenge, especially in terms of emergency evaluation planning. Drought and tectonic hazard remain difficult to forecast, although some success is possible. For example, based on early warning indicators, the Philippine Institute of Volcanology and Seismology advised the government to evacuate residents within a 20-mile radius of Mt Pantaloon before the volcanic eruptions of June 1991. Although hundreds of people were killed, over 10,000 homes destroyed and some US$ 260 million-worth of damage occurred, a further 80,000 people were saved together with an estimated 1 million US$ loss in USA. Forecasting and warnings tend to consist of a number of sequential and interrelated stages. These are: (1) Threat recognition the preliminary planning phase when a decision is taken to fund, plan and establish a Forecasting and Warning. To be effective such schemes need to be widely exposed among the community at risk and then tested with mock disaster exercises before a major hazard appears. Ideally, feedback form this experience leads to design improvements in the system. Other revisions should occur as a result of hindsight reviews. (2) Hazard evaluation includes several sub-steps, from trained observes first detecting an environmental change that could cause a threat, through to estimating the nature and scale of the hazard, and finally deciding to issue a warning to an endangered community. The task of evacuation is a technical operation, which is entrusted to a specialized agency such as a national meteorological or geological service. This is because of the need for continuous monitoring by comprehensive networks backed up with heavy investment in scientific equipment and personnel. The priority at this stage is to improve the accuracy of the forecasts and to increase the lead-time between the issue of the warning and the onset of the hazardous event. To complete the process, and to retain public confidence, stand-down messages should be issued when the emergency is over. (3) Warning dissemination occurs when the warning message is transmitted form the forecasters to the hazard zone occupants. The message is likely to be formula tied and conveyed by a third party through an intermediate medium which may involve different communication methods, such as radio or television, and different personnel, such as the police or neighbours. Again, the stage contains several components, such as the content of the message or the way in which it is conveyed, which are known to affect the eventual outcome. (4) Community response is the key phase where loss-reducing actions, such as property protection and evacuation, are taken, sometimes on a massive scale.

The priority at this stage is to improve the accuracy of the forecasts and to increase the lead-time between the issue of the warning and the onset of the hazardous event. To complete the process, and to retain public confidence, stand-down messages should be issued when the emergency is over. (3) Warning dissemination occurs when the warning message is transmitted form the forecasters to the hazard zone occupants. The message is likely to be formula tied and conveyed by a third party through an intermediate medium which may involve different communication methods, such as radio or television, and different personnel, such as the police or neighbours. Again, the stage contains several components, such as the content of the message or the way in which it is conveyed, which are known to affect the eventual outcome. (4) Community response is the key phase where loss-reducing actions, such as property protection and evacuation, are taken, sometimes on a massive scale.

It has been observed that the response may be influenced directly through an input based on the public’s own knowledge of the evolving hazard and various feedback mechanisms can help to improve later editions of the warning. However, the nature of the warning message and a range of factors, which bear on the recipient’s behavior, largely determine the response. The value of a Forecasting and Warning system depends on both the skill of the forecaster and the effective translation of the forecast into a warning. In other works, an understanding of the social setting is as important as the accuracy of the scientific information if the community responses are to achieve optimum loss reduction. Unfortunately, there has been a tendency for forecasting to become divorced form the remainder of the sequence because it relies so heavily on sophisticated equipment and complex modelling techniques. The decision to warn is crucial to the land. In marginal situations; forecasters have to make difficult decisions quickly. Problems of interpretation can occur at the interface between the evolution and dissemination stages where the transition from ‘forecast’ to ‘warning’ takes place. Less attention may be aided by a wish on the part of some agencies to avoid legal liability arising from the consequences of either defective forecasts or poor advice about damage-refusing actions. (5) The efficiency of hazard response is influenced by a number of factors, some procedural and some, which are due to the characteristics of both the message and its recipients. Tiered warnings, incorporating a ‘watch’ phase before the ‘warning’ phase, tend to avoid gross errors involving evaluation, but not all hazards, for example, earthquakes, are suitable for tiered warnings. Pre-planning should ensure that basic procedures are understood, such as the advance identification of the people and organizations to be warned. There should also be some alternative means available to distribute messages in adverse environmental conditions, which may include the loss of electrical power and communication systems. Preparedness programmes should also help hazard zone occupants to recognize the threat and to take suitable defensive actions, although there will always be some gap between what people are advised to do, what they say they will do and what they actually do in a stressful situation. (6) Feedback within the system, involving both an accuracy check on the forecasters and a response check on those being warned, is vital. This is because the onward transmission of the message may be unnecessarily delayed, or even halted, at various points by individual operators seeking confirmation of some aspect. This is most likely to happen with ambiguous messages like the Washington State Department of Emergency Services had before the eruption of Mount Saint Helens. Although released by an authoritative source, this message was not passed on to the community at risk because it lacked a sense of urgency, was not specific about the areas likely to be affected by ash fall and contained no guidance about precautionary actions which people were expected to take. It is now believed that effective warning messages should contain a moderate sense of urgency, estimate the time before impact and the scale of the event, and provide specific instructions for action, including the

need to stay clear of the hazard zone (Grluntfest, 1987). Advice on present environmental conditions and notice of when the next warning update will be issued are also helpful. (7) Planning for effective warnings should start with some knowledge of the perception and likely behaviour of those being warned. In turn, this will depend on the mode of warning. For the general public, the news media acts as the primary source of information about hazards and hazard warnings. However, there is evidence that, to be effective, a hazard warning is much more than the transmission of a message from a warning source to a large number of people. Both the mode of warning, as well as the content of the message, needs to be considered. For example, it is believed that the best warning messages are those that make the content personally relevant to those who are expected to act on the information (Fisher, 1996). In this context, mass communication may not be the best means of hazard dissimilation, and warnings delivered directly by other people are seen as more relevant. Although warnings via the mass media are likely to be believed if issued by government officials or an emergency organization, the initial media message is more likely to alert people to the fact that something is wrong rather than mobilize them to an immediate response. (8) Confirmation of the first warning received by an individual is almost always sought before any action is taken, hence the advantage of tiered warnings. For example, confirmation may be sought from neighbours or the police, and this mean that interpretation of the warning message normally takes place as a group response as opposed to that of an isolated individual. Not surprisingly, past experience with the same hazard increases the level or warning belief and there is some evidence that women are more likely than men to interpret a message as valid. Old and infirm people living alone are less likely to make an effective response to hazard warning, either in terms of protecting property or evacuating the premises, and there is a need for special support groups to be made available to such sections of the community. Often there is a reluctance to evacuate. This may be because the message fails to specify this action, or because people feel that they can cope, or because they fear looting of their empty houses. There is a considerable natural attachment to the home environment and the strength of family ties has been found to be significant in this context. Family groups are much more likely to evacuate than singleperson households, and often go to the homes of relatives rather than to disaster shelters. 6.

Such conversion increases unit land values and therefore leads to

greater economic losses when disaster strikes. The increasing competition for land makes this strategy important. In the MDCs too there has been an accelerating trend towards the invasion of previously avoided hazard-prone areas. In part this has been due to urban growth, but more affluence and leisure time has led to the erection of second homes and recreational facilities in environments such as coasts and mountains, which are intrinsically hazardous. The main purpose of land planning is to guide new residential commercial and industrial development away form identified hazard zones, but this is not always possible. Therefore, this approach has an additional role to play in reducing losses in areas already occupied whilst it can also help to steer new development away from environmentally sensitive areas, such as wetlands, because hazardbased land management normally has to function as a planning device within communities that are already there. It frequently seeks to combine the beneficial use of known hazard-prone areas with a minimum of hazard loss and expenditure. It is undertaken mainly at the local government level and, because it is part of the overall political process, it requires broad community support. Land use planning deploys regulatory tools on a variety of scales; form regional planning through town zoning ordinances down to plot sub-divisions bylaws. Land use measures are most likely to be adopted if they are encouraged by the national government. The approach works most obviously by prohibiting new development in very high-hazard areas but it can also deploy measures, which are less likely to be opposed by local developers. For example, whilst low-density zoning might be imposed in order to limit the potential property losses in an area, the builder concerned might be compensated by the granting of a permit for much higher density development in the nearest area. More than any other method of loss reduction, land use planning depends for its success on the allied use of other hazard mitigation measures, sometimes of a structural nature. It is also true that the wide-ranging implications of this measure sometimes bring it into conflict with other community objectives. This is because, in the process of converting land to higher intensity uses, several powerful local groups with vested interests are involved. These range from the original land-owners, whose motive is often capital gain, to developers and builders, who are also driven by profit. Conflict arises from the fact that, although such land management is undertaken as a public sector policy, it must control private sector ‘rent seeking’ behaviour before it becomes effective. The main practical limitations on regional land use planning are: (1) Lack of knowledge about the location, recurrence interval and hazard potential of events, which might affect small parts of urban areas; (2) The presence of extensive existing development; (3) The relative infrequency of many hazardous events and the difficulty of maintaining society awareness about the need to avoid hazard-prone land; (4) The high costs of hazard mapping, including detailed inventories of existing land use, structures, occupancy levels, etc.; (5) Local resistance to land use controls on political or philosophical grounds (Beatley, 1988); (6) Profit-seeking processes which seek to pass the hazardrelated costs on to others.

greater economic losses when disaster strikes. The increasing competition for land makes this strategy important. In the MDCs too there has been an accelerating trend towards the invasion of previously avoided hazard-prone areas. In part this has been due to urban growth, but more affluence and leisure time has led to the erection of second homes and recreational facilities in environments such as coasts and mountains, which are intrinsically hazardous. The main purpose of land planning is to guide new residential commercial and industrial development away form identified hazard zones, but this is not always possible. Therefore, this approach has an additional role to play in reducing losses in areas already occupied whilst it can also help to steer new development away from environmentally sensitive areas, such as wetlands, because hazardbased land management normally has to function as a planning device within communities that are already there. It frequently seeks to combine the beneficial use of known hazard-prone areas with a minimum of hazard loss and expenditure. It is undertaken mainly at the local government level and, because it is part of the overall political process, it requires broad community support. Land use planning deploys regulatory tools on a variety of scales; form regional planning through town zoning ordinances down to plot sub-divisions bylaws. Land use measures are most likely to be adopted if they are encouraged by the national government. The approach works most obviously by prohibiting new development in very high-hazard areas but it can also deploy measures, which are less likely to be opposed by local developers. For example, whilst low-density zoning might be imposed in order to limit the potential property losses in an area, the builder concerned might be compensated by the granting of a permit for much higher density development in the nearest area. More than any other method of loss reduction, land use planning depends for its success on the allied use of other hazard mitigation measures, sometimes of a structural nature. It is also true that the wide-ranging implications of this measure sometimes bring it into conflict with other community objectives. This is because, in the process of converting land to higher intensity uses, several powerful local groups with vested interests are involved. These range from the original land-owners, whose motive is often capital gain, to developers and builders, who are also driven by profit. Conflict arises from the fact that, although such land management is undertaken as a public sector policy, it must control private sector ‘rent seeking’ behaviour before it becomes effective.

Earthquake Hazard Management

Regional land use planning is most useful in communities that are still growing and which have undeveloped land. Successful land management techniques also depend on the availability of information with which to identify particularly hazardous locations. Indeed, the accurate delimited hazard zones are crucial because the entire policy is based on the detailed recognition, and the community acceptance, of different degrees of risk, which, in turn, justify the implementation of selective development controls. Ideally, variegation in risk should be identifiable down to the level of individual properties. For many hazards, such as cyclones and earthquakes, such precision is unattainable. The greatest accuracy is achieved with topographically controlled hazards such as floods, landslides and avalanches. Micro-zonation, or regional planning, can help to steer broad policy decisions. For example, in a regional map of the seismic risk in New Zealand, there, could be use to delineate national priority areas for retrofitting existing buildings with anti-seismic measures or for the introduction of anti-seismic building codes for new development. Micro-zonation works at the local planning scale when it deals with individual communities and building lots. Zoning ordinances are used to implement the regional plan. They can be used to control development through the provision of reports on aspects such as soils, geological conditions, grading specifications, drainage requirements and landscape plans. Relatively large-scale maps (at least 1:10,1000 are usually required for zoning in high-risk urban areas, as shown by the seismic survey for Tokyo (Nakano and Matsuda, 1944). Other regulations can then be used for more detailed analysis as individual applications are submitted for permission to develop the land at the building plot level. For example, subdivision regulations ensure that the conditions under which land may be subdivided are in conformity with the general plan. Seismic micro-zonation has been a goal in the mitigation of hazards. It may be used to restrict development behind some minimum set-back distance from an active fault-line thus, the special risk zone’s act stipulates that a structure shall not be located across the trace of an active fault and that a uniform 50 foot (15 m) set-back from the fault line is normally required. If development is allowed, zoning can be used to maintain low levels of building density, perhaps by requiring only large lots to be developed or by dedicating areas to openspace uses, such as parks or grazing. Some uses, such as industrial activity may be propitiated. The weak structured buildings should be retrofitted. Trigger Mechanism Required for Disaster Management 1. 2. 3. 4. 5.

It is well known that the community participation can play a vital role in each and every stage because if the training programmes and rescue trainings, first-aid training, search and rescue demonstration programmes are orientated in each and every level, than it is sure that the vulnerability can be reduced. The rescue training should be compulsory at school, college, and university level. Each government servant and public servant should participate in such kind of training as search and rescue, first aid training at least three times in a year which will be compulsory to all students as well as teachers, professors and all government and private labourers. For this training, programmes the above channel can be followed: • •

Identification and strengthening of existing centres of excellence in order to improve disaster prevention, reduction and mitigation capabilities. Emergency Support System should be very effective in which communication, public health, sanitation, power, transport, media, donation, search and rescue operations, food, public works and engineering, information and planning, relief supply , drinking water, shelter and medicines should come in the combined package in which all the teams should work together towards the natural hazards and disaster mitigation

CONCLUSION Once the high-risk areas have been identified, a number of options can be considered. The public acquisition of hazard-prone land is the most direct measure available to local government and is one of the most effective longterm strategies.

relocation which involves moving structures and occupants form a hazard area is much more difficult and expensive than the acquisition of vacant land; also, it is often highly controversial within the community. For example, it may well be opposed by advocates of economic development if it is seen to destroy any potential the land might have to promote growth or generate local tax revenues. In some cases public land acquisition could involve the purchase and demolition of buildings, which are of historical or architectural importance and thus generate opposition from pressure groups. Hazard-prone land often appears very desirable. Many landslide areas and floodplain sites have outstanding scenic views and can command high market prices if there is a low awareness of the hazard threat. Under the ancient legal doctrine of caveat emptor (‘let the buyer beware’), there is usually no obligation for the owner of such land to disclose the risk to an intending purchaser. However, there is a growing demand that the vendor should have a statutory duty to make a prior disclosure of geological and other environmental hazard in real estate transactions so that the potential buyer can make a more informed choice (Binder, 1998). Such legal impediments to building construction are unpopular with local commercial interests, such as land developers, builders and estate agents. Under pressure from these groups, local authorities may refuse to adopt land use regulations in the belief that they will lose economic initiatives to more lenient communities nearby. For these reasons, any regulations adopted must be seen to be reasonable and capable of defence in a court of law. Public education and other voluntary methods can sometimes be more useful than legislation in discouraging development in hazardous areas. Some of the oldest methods rely on public information to divert development away form such zones. For example, warning signs that are readily visible help to alert both potential developers and purchasers of the hazard. Since any effective hazard-reduction strategy depends on the understanding and cooperation of the community, public information programmes are essential aids to awareness. These programmes may operate through a wide variety of dissemination means, including conference, workshops, press releases and the publication of hazard zone maps. Financial measures can also be important in discouraging development in hazardous areas, largely because of the great significance of the profit motive in promoting land use conversion. Unlike land acquisition and zoning, which directly control development, the use of financial incentives and disincentives affect development indirectly by altering the relative advantage, which people may see in building in a hazard zone. For example, the appropriate local government body may elect to locate any investment in public facilities, such as roads, water mains and sewers, only in those areas deemed hazard-free and zoned for development. Any national government programme that provides grants, loans, tax credits, insurance or other types of financial assistance has a large potential effect on both public and private development. Tax credits may be used as an incentive

to reduce a property owner’s tax liability as long as hazard-prone land is either left undeveloped or developed at a very low density. Rather less popular are the financial disincentives which act as a deterrent to land use conversion in hazard areas. For example, the US Congress introduced provisions into the flood disaster protection act of 1973 to withhold federal benefits from floodprone communities that did not take part in the national flood insurance programmes. Other distinctions include the denial of a loan by a private source of government lending agencies, and the fact that, under some legal system, civil liability may be recognized for death, bodily injury, property damage and other losses, which might ensue from the erection of buildings on land, designated as hazardous. These difficulties can be reduced by pre-designating centralized control of the relief operation. It should also be recognized that basic services such as roads, water supplies or telephones, are unlikely to fully be available and a wider practical knowledge of appropriate self-help techniques-such as first aid, search and rescue and fire-fighting–should be promoted within communities at risk, as this type of team in India is known by the Civil Defence and Home Guards squads. Overall there is a vital need of local awareness, pre-preparedness of society, an adaptation to the hazard resistant designs, use of the retrofitting techniques wherever recommended, preparing the hazard and risk zones maps, proper land use planning and diffusing the information among the locals regarding the Disaster Management. Focus is on the Disaster Management programmes and preparing the task force or group to rescue the lives. Self-help techniques-such as first aid, search and rescue and fire-fighting–should be promoted at the school and college level, and they should be a part of study in each discipline, and it should be an essential subject in all classes and for all students at various levels.

Temporal Transport Hazard Dynamics: A Case Study of Delhi R.B. Singh and Swarnima Singh Department of Geography, Delhi School of Economics University of Delhi, Delhi-110007, India

INTRODUCTION Transport plays a significant role in the overall development of a nation’s economy.

bronchial problems and visibility. The pollution from vehicles is due to discharges like CO2, unburned HC, Pb compounds, NOx, soot, suspended particulate matter (SPM) and aldehydes, among others, mainly from the exhaust pipes. According to the World Health Organisation’s recent study report in Delhi one out of every 10 school children suffers from asthma and that is worsening due to vehicular pollution. Similarly, two of the three most important health related problems in Bangkok are caused by air pollution. 4 to 8 per cent of deaths that occur annually in the world are related to air pollution and of its constituents, the WHO has identified SPM as the most sinister in terms of its effect on health. This is a concern that has been reflected in the Agenda 21 as well. Without adequate means of transport and transport routes, there can be no development of industry or trade. All types of transport—automobiles cars, buses, trucks, etc., carts drown by bullocks, camel and horse, and railway run on the land, while steam or motor launches, country boats and shipping vessels run on water and aeroplanes fly in the air—are the prevalent means of transport in the country. Transportation assumes greater significance in the urban context. Desire lines emanating from the existing land use pattern and then reinforced by accepted transport management solutions, give rise to the traffic congestion problem of large urban conglomerates (National Commission of Urbanisation 1999). The Transport Sector and Agenda 21 The concerns related to the impact of the transport sector on environment and energy highlighted earlier is reflected in Agenda 21 as well. The overall objective outlined in the paper is to reduce the local and global emissions from all modes of the transport sector. Agenda 21 have identified the following key issues in the transport sector: • Promoting integrated transport policies that consider alternative approaches to meet commercial and private mobility needs. • Integrating land-use and urban and rural transport planning, taking into account the need to protect ecosystems. • Improving efficiency of transportation and related sectors. • Accelerating phasing-out of the use of leaded gasoline. • Promoting voluntary guidelines for environmentally-friendly transport and action for reducing vehicle emissions. • Fostering partnerships at the national level for strengthening transport infrastructure and developing innovative mass transport schemes.

Land: Use Changes Sustainable urban development is the most important concern for Delhi’s current environmental crisis at the threshold of the 21st Century. The population of Delhi is estimated to rise to 22.42 million persons by 2021. The cheapest means of passenger transport in Delhi are the buses provided by the Delhi Transport Corporation (D.T.C.) and the Delhi Metro which is under construction. The significance of the environment was routinely mentioned in heavy words in the Master Plans of Delhi-MPD-1962, MPD-2001 and MPD-2021. However, in Delhi, land environment is under stress due to the increasing pressure of population. Urban Population, industry and commerce are widespread and natural vegetation destruction is all over the Delhi Ridge resulting in the shrinkage of the ‘Green Lung’ of Delhi. Likewise Delhi’s urban area has grown from 200.52 km² in 1951 to more than 658.34 km² in 2001. The urban density has grown from 1,812 in 1921 to 19,473 persons per sq. km in 2001. The traffic conditions in Delhi, in all its dimensions, represent the transport system in the city. Transportation assumes greater significance in the urban context. Desire lines emanating from the existing land use pattern and then reinforced by accepted transport management solutions, give rise to the traffic congestion problem of large urban conglomerates. The given fig no. 1, is showing the comparative complexity of Delhi’s land use pattern, means the changing face of agricultural land into flyovers can be clearly found in our given map given map.

Land: Use Changes Sustainable urban development is the most important concern for Delhi’s current environmental crisis at the threshold of the 21st Century. The population of Delhi is estimated to rise to 22.42 million persons by 2021. The cheapest means of passenger transport in Delhi are the buses provided by the Delhi Transport Corporation (D.T.C.) and the Delhi Metro which is under construction. The significance of the environment was routinely mentioned in heavy words in the Master Plans of Delhi-MPD-1962, MPD-2001 and MPD-2021. However, in Delhi, land environment is under stress due to the increasing pressure of population. Urban Population, industry and commerce are widespread and natural vegetation destruction is all over the Delhi Ridge resulting in the shrinkage of the ‘Green Lung’ of Delhi. Likewise Delhi’s urban area has grown from 200.52 km² in 1951 to more than 658.34 km² in 2001. The urban density has grown from 1,812 in 1921 to 19,473 persons per sq. km in 2001.

Temporal Status of Air Pollution The rapid urbanization together with the increasing demand for urban transport, the continuous growth of vehicle usage, energy and population density in the urban areas, are contributing to the levels of urban air pollution, especially near heavy traffic or highly congested roads, and the very high levels reached are generally much higher than the safe standards recommended in Delhi, causing various natural problems as for example: Acid rain, greenhouse gas effects, climatic change in the city. That is why the temporal study of air pollution is very important. The vehicles propelled by two-stroke engines illustrate the public policy challenge: Such engines resemble those of highly inefficient lawn mowers, regularly producing oily clouds of smoke. Also, these vehicles account for 70 per cent of the total vehicle population and 67 per cent of the total air pollution load (approximately 3,000 metric tonnes per day) in Delhi. (CPCB 2004). Delhi is amongst the fastest growing cities of the world. Sustained concentration of population in old areas along with continued expansion of the city in the periphery has produced high intensity and low intensity polluted areas. The poor and old city residents concentrated in high density areas, perhaps experience higher exposures to air pollutants due to the very slow moving vehicular traffic and the presence of unregulated vehicular traffic like Phat Phat Sewa, Tampoo etc. (IIT Delhi, 2001). There is a major shift in the sectoral contribution of pollution, (table 3). Initially the major threat was industry because of the high growth for basic sustenance. Industrial development has been haphazard and unplanned but this scenario has been changed because of many reasons and now transport is playing a disastrous role. The rising incomes and urbanization are largely responsible for the rapid increase in the vehicular population in Delhi. This pattern of

The rapid urbanization together with the increasing demand for urban transport, the continuous growth of vehicle usage, energy and population density in the urban areas, are contributing to the levels of urban air pollution, especially near heavy traffic or highly congested roads, and the very high levels reached are generally much higher than the safe standards recommended in Delhi, causing various natural problems as for example: Acid rain, greenhouse gas effects, climatic change in the city. That is why the temporal study of air pollution is very important. The vehicles propelled by two-stroke engines illustrate the public policy challenge: Such engines resemble those of highly inefficient lawn mowers, regularly producing oily clouds of smoke. Also, these vehicles account for 70 per cent of the total vehicle population and 67 per cent of the total air pollution load (approximately 3,000 metric tonnes per day) in Delhi. (CPCB 2004).

There is a major shift in the sectoral contribution of pollution, (table 3). Initially the major threat was industry because of the high growth for basic sustenance. Industrial development has been haphazard and unplanned but this scenario has been changed because of many reasons and now transport is playing a disastrous role.

As cities grow in size, the number of vehicular trips on the road system goes up. This necessitates a pragmatic policy shift to discourage private modes and encourage public transport once the level of traffic along any travel corridor in one direction exceeds 20,000 persons per hour. Today the traffic on the roads of Delhi is a heterogeneous mix of cycles, scooters, buses, cars, and rickshaws jostling with each other. This has resulted in a chaotic situation so much so that due to suffocation, health diseases, road accidents etc. the average number of persons killed per day has increased to 7 and of those injured to 18. The position is expected to deteriorate further in the years to come. To rectify this situation the Government of India and the Government of the National Capital Territory of Delhi, in equal partnership have set up a company named Delhi, Metro Rail Corporation Ltd. under the Companies Act of 1956 which has constructed 65.11 Kms of Metro Rail tracks in Delhi till 2006 to decrease the population load in buses and to decrease the pollution load of Delhi’s environment.

However the concentration of SPM stays above the safe mark of 200mg/m³ and shows a more or less rising trend through the decade and only after 2001 a fall in its concentration is observed.

The Central Pollution Control Board has taken Data on six monthly average pollutant’s levels for seven functioning monitoring stations from October 2001 to March 2002 (Central Pollution Control Board). The 7 functioning monitoring stations comprise five residential areas viz. Ashok Vihar, Indraprastha (ITO), Nizamuddin, Siri Fort and Janakpuri; and two industrial areas viz. Shahdara and Shahzada-Bagh. All the seven functioning monitoring stations are put in the ascending order of SPM levels and the line graph for the three air pollutants viz. SPM, SO2 and NOx are presented in the table below (Fig 9). As noted earlier the concentration levels of NOx and SO2 are found to be within the safe limits excepting for the NOx level (68) in Indraprastha (ITO). However, the SPM levels in all of the seven monitoring stations in Delhi are much higher than the safe level allowed (200mg/m3). Interestingly a broad find shows that the lowest average level of SPM is found in Indraprastha (228) compared with the maximum average of around 543 in the industrial area of Shahzada Bagh. In all theother five monitoring stations we find the yearly average SPM level ranges between 311 in Nizamuddin to 388 in Ashok vihar due to vehicular concentration. In cities like Mumbai, Ahmedabad and Nagpur, the annual average of SPM is at least three times higher than WHO standards and in Delhi, Kolkata and

As noted earlier the concentration levels of NOx and SO2 are found to be within the safe limits excepting for the NOx level (68) in Indraprastha (ITO). However, the SPM levels in all of the seven monitoring stations in Delhi are much higher than the safe level allowed (200mg/m3). Interestingly a broad find shows that the lowest average level of SPM is found in Indraprastha (228) compared with the maximum average of around 543 in the industrial area of Shahzada Bagh. In all theother five monitoring stations we find the yearly average SPM level ranges between 311 in Nizamuddin to 388 in Ashok vihar due to vehicular concentration. In cities like Mumbai, Ahmedabad and Nagpur, the annual average of SPM is at least three times higher than WHO standards and in Delhi, Kolkata and

and 10 persons per vehicle respectively for Mumbai, Kolkata, Chennai and all India. The characteristic feature of the transport system is the pre-dominance of private vehicles, which comprise about 90 per cent of the total vehicles in Delhi, but cater to around 40 per cent of the total traffic load. One of the most significant measures that have been taken in Delhi is the introduction of Compressed Natural Gas (CNG) as the fuel for all public transport. The significance lies in the fact that it was carried out following active interventions by the Supreme Court of India. Institutional failures also led to delays and problems in implementation. Along with CNG conversion for all public transport vehicles and the phased introduction of the metro rail system in Delhi, cleaner diesel is also being supplied in the city in the last three years. The sulfur content in the diesel oil supplied to the metropolitan cities (Delhi, Mumbai, Chennai and Kolkata) has been decreased during the year 2000 from 1 per cent sulfur by weight to 0.25 per cent by the Indian refineries as per the Indian government directives. The sulfur content has been further reduced to 0.05 per cent by weight in Delhi by late 2001. In spite of this, there are significant developments and environmental benefits from the experience. The following section presents the entire transition process, beginning with the orders given by the Supreme Court that led to the adoption of CNG, to the implementation process, especially the institutional failures which drew insights from the experience. Judicial intervention in the air pollution problem in Delhi started after a Public Interest Litigation (PIL) was filed by an environment activist lawyer in the Supreme Court in1996. The PIL, namely M.C. MEHTA versus Union of India and others, called for measures to improve the air quality in Delhi. After several hearings, the Court passed orders in 1998 that gave a time frame for implementing measures to control vehicular pollution in the National Capital Region of Delhi. With the implementation of various pollution control measures and the introduction of CNG, the pollution level of Delhi goes on decreasing. As the above graph (Fig. 10) shows the major fall in the level of disastrous lead from

The characteristic feature of the transport system is the pre-dominance of private vehicles, which comprise about 90 per cent of the total vehicles in Delhi, but cater to around 40 per cent of the total traffic load. One of the most significant measures that have been taken in Delhi is the introduction of Compressed Natural Gas (CNG) as the fuel for all public transport. The significance lies in the fact that it was carried out following active interventions by the Supreme Court of India. Institutional failures also led to delays and problems in implementation. Along with CNG conversion for all public transport vehicles and the phased introduction of the metro rail system in Delhi, cleaner diesel is also being supplied in the city in the last three years. The sulfur content in the diesel oil supplied to the metropolitan cities (Delhi, Mumbai, Chennai and Kolkata) has been decreased during the year 2000 from 1 per cent sulfur by weight to 0.25 per cent by the Indian refineries as per the Indian government directives. The sulfur content has been further reduced to 0.05 per cent by weight in Delhi by late 2001. In spite of this, there are significant developments and environmental benefits from the experience. The following section presents the entire transition process, beginning with the orders given by the Supreme Court that led to the adoption of CNG, to the implementation process, especially the institutional failures which drew insights from the experience. Judicial intervention in the air pollution problem in Delhi started after a Public Interest Litigation (PIL) was filed by an environment activist lawyer in the Supreme Court in1996. The PIL, namely M.C. MEHTA versus Union of India and others, called for measures to improve the air quality in Delhi. After several hearings, the Court passed orders in 1998 that gave a time frame for implementing measures to control vehicular pollution in the National Capital Region of Delhi. With the implementation of various pollution control measures and the introduction of CNG, the pollution level of Delhi goes on decreasing. As the above graph (Fig. 10) shows the major fall in the level of disastrous lead from

The particulate lead concentrations appear to be getting under control which is attributable to the delegating of petrol and restrictions and less SO2 levels in overall cases because of less industrialization. Due to high population pressure and large industrial and commercial activities, the high economic proficiency of Delhi has now manifested itself as the root cause of serious environmental problems. Consequently, the work carried out will add to our knowledge on the sustainable urban environmental development in Delhi. In fact, the containment of vehicular pollution requires an integrated approach, with the following components: 1. Improvement of public transport system. 2. Optimisation of traffic and improvement in traffic management (e.g., area traffic control system, timers at intersections, no traffic zones, green corridors, removal of encroachment on roads, regulation of the digging of roads). 3. Comprehensive inspection and certification system for on road vehicles. 4. Phasing out of grossly polluting units. 5. Fuel quality improvement (e.g., benzene and aromatics in petrol, reduction ofsulphur in diesel). 6. Tightening of emission norms (e.g., EURO-IV). 7. Improvement in vehicle technology (e.g., restriction on manufacturing of 2-stroke engines, emission warranty, on-board diagnostic system). 8. Checking fuel adulteration, and 9.

INTRODUCTION

INTRODUCTION

As a consequence of disasters and emergencies, significant quantities of solid waste is often generated from sources other than the normal daily generation of Municipal and Industrial waste. This “new” waste derives itself from both the damaged built environment and housing/industrial facilities, as well as from the subsequent relief and rehabilitation efforts. Considering the often large quantities of such solid waste produced, early action within the relief and rehabilitation programming is required in order to manage and handle this waste in both an economically and environmentally sound manner. In the absence of such intervention, serious risks may result from the rapidly accumulating solid waste, including: 1. The danger to public health from open dump sites resulting in the unpleasantness from odour and the visual impact as well which are both assisting in the spread of diseases through human contact with the decomposing waste, 2. The increase in the vermin population at the site of waste dumping is often close to residential areas, 3. Groundwater contamination due to the dumping of waste near water courses (rivers, streams and lakes) from the leaching waste, which in turn can contaminate the drinking water. 4. Uncontrolled dumping of waste leading to the obstruction of reconstruction works and daily traffic routes for the public.

Disaster Management

The term disaster may be defined as meaning an event which overwhelms a local capacity, necessitating a request to a national or international level for external assistance.” (Disaster Databases, 2001). It includes both “natural” disasters, i.e. earthquakes and hurricanes, as well as “man-made” disasters, such as conflicts. The term ‘waste’, includes solid waste, which mainly comprises municipal and household waste as well as demolition waste from the demolition of damaged buildings. KEY ISSUES The key issues arising from the management of solid waste following disasters are: 1. The collapse of Municipal solid waste utilities, including the probable lack of collection services and the uncontrolled tipping of wastes. This would result in a rapid build up of waste piles in the streets and outside the urban areas resulting in vermin growth and the spread of diseases. The potential is there for there an impact on environmental health issues and is serious in residential areas. 2. Additionally, the waste management equipment viz. collection vehicles and waste containers, are often damaged or looted during or after a disaster, especially in the case of post-conflict situations. 3. The loss of senior and experienced waste management professionals, either through death or departure from the area as a refugee. 4. The uncontrolled tipping of health-care waste from hospitals and clinics, resulting in serious hygiene risks to the local population and secondary infection to patients. 5. Building rubble from damaged buildings piled in urban areas, impeding the movement and affecting rehabilitation / reconstructive activities. Piles of rubble attract further waste tipping and this becomes a “waste dump”. 6. Hazardous waste from damaged and redundant industrial plants may pose serious health risks through uncontrolled containment and handling. 7. Proliferation of scattered waste piles and dump sites leading to health risks (vermin and personal contact to waste) with the risk of contaminating groundwater 8. In more common scenarios, waste is often addressed in an ad hoc fashion, and more along the lines of supplying equipment and funds for clean-up works, rather than a focus on capacity building and institutional strengthening. Without these skills in training and management support, the provided equipment can be under-utilized and quickly become damaged due to its improper use and low maintenance.

In the absence of a dedicated and approved landfill for the waste, the use of temporary open dumpsites located out of the city may be the only option initially. Once the collection system is established, open dumps may be converted into controlled dump sites using a variety of low-tech approaches. This involves improving the gate control of vehicles entering the site, strict direction of vehicles on where to discharge loads, a small tipping area, flatten or covering up of the areas of the site not in use, elimination of fires and allowing licenced groups of scavengers to collect specific materials and to police their takings from others. Later on, simple methods such as draining away surface water, erecting a gate and gatehouse at the entrance and widening the access road on busy sites to allow vehicles to pass in both directions, may further improve the managed status of a disposal site. The disposal of hazardous waste, i.e. from hospitals or industries, should be in special cells within the dump site or landfill. Where possible, these must be controlled with a clay lining and cover daily to reduce the risks of leachate and unsupervised human contact. With regards to demolition waste, specific recycling depots can be established for the storage and subsequent processing with crushers and screening plants. Such recycling is relatively simple and can produce a recycled gravel useful for road construction and low strength concrete.

Larger quantities may be carried by animal carts and tractor-trailer methods but they require money to be available to hire the vehicles. Local scavengers can be mobilised into co-operatives to offer a paid collection for household waste collection. If funds and resources are available for mechanized waste collection, for the prevailing density of the waste, a skip based collection system would be more appropriate to introduce than the use of waste collection vehicles. The latter are expensive to maintain and would provide little or no improvement in vehicle payloads. In the post-disaster phase, disposal sites are in high demand and this space needs to be allocated for non-recyclables with the majority of recyclables being diverted to recycling depots. This can, however, prove difficult due to the collection of large amounts of debris in the streets blocking movement. In addition, such sites often tempt the residents to dispose of their household waste, thus increasing the health hazards and mixing the potentially recyclable demolition waste with household waste. As for as construction and demolition waste is concerned, it will often be the contractor agency who would be responsible for the haulage of the waste, which can be routed to a specific recycling depot for processing into recycled gravel and aggregate for future use in construction work. In the case of clinical waste from hospitals, multi bin sorting systems may be implemented whereby the various types of waste are placed in colour coded bins, which are then either burnt in the hospital incinerator or disposed of as hazardous waste.

INTRODUCTION Mangrove forests are best developed on tropical shorelines where there is an extensive suitable intertidal zone, with an abundant supply of fine grained sediment, and are most luxuriant in areas with a high rainfall or an abundant fresh water supply. Mangroves thrive on river discharge and cover up to 75% of coastlines (Pernetta, 1993). Mangroves in the developing countries, especially in the south Asian region, are under threat from over-exploitation, destruction and environmental degradation (Ong et al., 1995; Tomlinson, 1995). Human communities in these developing countries use mangroves for wood and tannin products on a sustainable level (Tomlinson, 1995). In addition, mangrove forests also act as a buffer zone between the open ocean and the land. This not only protects the shores from erosion and siltation (Furukawa and Wolanski 1996), but also provide habitat for many commercially important biological resources. The biogeochemistry of the mangrove forest is not only influenced by the anthropogenic factors but also by the natural forces. The nutrient biogeochemical processes in mangroves are primarily driven by both internal and external factors, such as creek hydrology, topography, tidal exchange, nutrient loading, microbial

transformation, biological interactions etc (Dittmar and Lara, 2001). Any disturbances in the creek hydrological structure will result in a variability in nutrient levels across the ecosystem. On the 26th December 2004, the Sumatra – Andaman earthquake in the Indian Ocean resulted in a tsunami along the coastlines of the nations sharing the Indian Ocean. India was one of the most damaged countries. The waves along the southeast coast of India were raised to > 20 – 25 m height with a speed of > 356 kmph and encroached around 3 – 5 km of the terrestrial land for quite some time. This has caused huge damage not only to human life and property but also to the imbalance of the natural system’s stability. However, the Pichavaram mangrove forest lying along the southeast coastline of India had reduced the speed and encroachment of the giant Tsunami waves at the Bay of Bengal, thus several hundreds of the Irula tribal population were saved from this natural calamity (Swaminathan, 2005), but the structure and function of the mangrove forest has changed by the destructive nature of the ocean waves. It is hypothesized that the reductive sedimentary environment of the mangrove has been altered by the Tsunami waves and this fact has a profound influence on the biogeochemical cycles. In an integrated assessment of the Tsunami impact on the Pichavaram mangroves, we have observed relatively significant changes in the water and sediment characteristics. Here, we present some results on the impact of the Tsunami on the biogeochemical characteristics of the water and sediments of the Pichavaram mangrove coastal forest of the south east coast of India.

The Pichavaram mangroves (Lat 11° 25’ N and Long 79° 47’ E) cover an area of 1100 ha; the area is traversed by a large number of channels and creeks connecting two major rivers, the Coleroon in the south and the Vellar in the north (Figure 1). The climate is sub humid and the ratio between precipitation and evapotranspiration (P/Etp) ranges from 0.5 to 0.75 (Selvam, 2003) with a maximum precipitation during the northeast monsoons (October-December). The Pichavaram mangrove forest is separated from the Bay of Bengal by a narrow sand bar during summer and is periodically flooded by the incoming tidal waters. Sampling and Analysis Water and sediment samples from the Pichavaram mangrove environment were collected before - (July 2004) and after the Tsunami (January 2005). The locations of the sampling stations were recorded using a Geographic Position System (GPS). The samples were collected from the same locations for comparison. The water sampling locations were chosen to present different parts of the mangrove.

The samples were thoroughly homogenized by using corning and quartering techniques. One portion of the sample was used for grain size analysis and the rest was used for nutrient analysis. Size separation for the sample was carried out following the standard sieving and sedimentation methods. The samples were dry sieved on an electrically controlled electromagnetic sieve shaker FRISCH ANALYSETTE-3. The samples were also analysed for C, N and S by a Beckman TOC Analyzer, for total nitrogen on a Perkin – Elmer 2400 CHNS/O Series II analyzer.

Tsunami Impact on Nutrient Dynamics

Figure 1 explains the variations in the water chemistry parameters of the Pichavaram mangrove waters before and after the Tsunami. The mangrove water is alkaline in nature in both conditions, without much systematic spatial variation irrespective of different conditions and seasons (Mook and Koene 1975). Pretsunami mangrove water was more highly alkaline than post-tsunami and this is because of the mixing of sea water with mangrove water and by the productivity process i.e. photosynthesis because the CO2 utilization, shifts the equilibrium towards highly alkaline. Then the retreating Tsunami waves mixed with the fresh water which later remained stored in the mangrove interior creeks for a considerable period of time besides disturbing the aquatic photosynthesis, resulting in a low alkalinity in post-tsunami water. A higher level of salinity was observed in the post-tsunami waters (avg. 27.89, SD 1.39) than in the pre-tsunami waters (avg. 21.83, SD 2.81). Salinity is known to control the availability of nutrients for the biological productivity in the coastal waters (Prasad et al. 2006). The chloride and sulphate ions are the dominant ions and control the salinity in the mangrove water (Ramanathan et al. 1999). Since the Pichavaram Mangrove forest is lagoonal in type, the residence time of the water is high and the stored Tsunami water which is rich in chloride and sulphate got subsequently released and these ions found their way into the creeks, thus the salinity of the mangrove water increased by 0.78%. The dissolved oxygen (DO) levels were increased significantly after Tsunami by 42% (avg. 7.79, SD 0.96;). The significant rise in DO after the Tsunami was due to the displacement of bottom water by the surface waters and the more rapid mixing, enabled more atmospheric oxygen to dissolve into the water (Prasad and Ramanathan, 2005). Bicarbonate is showing conservative behaviour in the mangrove waters (Fig. 2). The wide variations at certain places are due to external loading i.e. terrestrial input and internal loading, i.e. mineralization of organic matter. Site × event differences (ANOVA) explain not much variance (27%), thus, it is showing conservative behaviour. Carbon is the nutrient which has been used by both biological and geological processes and behaves as both sink and source (Kalpan and Newbold, 2000). Carbon dynamics in coastal waters is regulated by the atmospheric conditions i.e. dissolution of CO2 in the water (Borges et al. 2003). Further, the weathering process also controls the carbon dynamics in the water column (Prasad and Ramanathan, 2005). The observed carbon and nitrogen levels are lower in the Pichavaram sediments compared with other mangroves (Boto, 1992). The C/N ratio is also low (pre-Tsunami 3.98; post-monsoon 3.12), suggesting that liable organic matter is dominant. Since the freshwater discharge from adjoining rivers is declining in recent years (Subramanian, 2004) the nutrient levels are higher. This shows that the river contribution is less and the

enhanced nutrients were derived from adjacent agricultural fields and aquaculture ponds. Salinity also seems to control the bicarbonate dynamics in mangrove water. In post-Tsunami waters HCO3 was increased by 11.32% from 5638 ƒ  mol/L. HCO3 has a significant positive correlation with salinity (r2 = 0.54, P < 0.05) in the post-Tsunami waters than with the pre-Tsunami water. The higher HCO3 may be derived from the marine input through the fluxing of the ocean water towards the terrestrial end and at a high energy situation, the vertical mixing of the water column contributes a considerable amount of stored inorganic carbon as dissolved HCO3 into the creek water. This inorganic carbon is fixed by the biological systems and is effectively transported into the trophic chain. Dittmer et al. (2006) reported that mangroves supply 2.2 × 1012 mol C year-1 to the continental shelf, which is an approximately accounting for > 10% of dissolved organic carbon (DOC) which is globally transported from the continents to the oceans. In turn, this increased HCO3 in the mangrove water will have a considerable influence on the global carbon cycle. Nitrate in pre-Tsunami waters ranged from 148 to 234 µ mol/L (avg. 209 µ mol/L) and increased to 28% in the post-Tsunami waters (220-302 µ mol/L, avg. 255 µ mol/L). NH4 concentrations in pre-Tsunami waters ranged from 6.11 to 10.56 µ mol/L (avg. 7.82, SD. 1.25) and post-Tsunami waters 12.78 to 36.67 µ mol/L (avg. 26.17, SD 7.11). Both the N species showed a significant site × event difference (ANOVA), with a variance of 69.5%. Generally, freshwater advection seems to be the major source of nitrate in the monsoon period. The Tsunami water mixed with the Vellar and Coleroon estuary through the channel ways carries a considerable amount of the nitrate into the Pichavaram Mangrove Forest. In general, high salinity accelerates the microbial nitrification (Dham et al. 2002) and lowers the ammonia concentration in the mangrove waters. Ammonia levels in the mangrove water column are influenced by the tidal wetting, plant uptake and seasonal changes in microbial decomposition, temperature and rainfall (Boto, 1982, 1984; Boto et al., 1985). The high levels of ammonia were due to higher fluxes of NH4+ derived from the benthic organic matter decomposing in sediments, which got re-suspended due to the disturbance of the sediment structure by the scooping effect of the Tsunami waves. High rates of sulphate reduction were observed in the Pichavaram (21-319 m mol S m-2 d-1) to depths of up to 1 m (Alongi et al., 2005) which implies that the high rates of ammonium regeneration cause a possible lateral flux via a groundwater discharge. Further, higher nutrient runoff from adjacent agricultural and aquaculture fields, domestic settlements and industrial units (Subramanian 2004) are likely sources which could accelerate the N species levels in the Pichavaram waters after a Tsunami. Nitrate shows a significant positive correlation with salinity occurring in the post-Tsunami (r2 = 0.72; P < 0.05) than in the pre-Tsunami (r2 = 0.47; P < 0.05). NH4+ also having the positive relationship with salinity in the pre-Tsunami (r2 = 0.43; P < 0.05) and post-Tsunami (r2 = 0.59; P < 0.05). This explains that salinity has quenching

Sulphate is generally derived from oxidative weathering of sulphide bearing minerals like Marcasite (which is abundant in these regions), but the sudden shoot of these ions that to above 500 mgl-1 is a clear indication of the role played by tsunami waters. Dominance of anions in the study area is as follows; Cl>HCO3>SO4 in both pre-tsunami and post-tsunami. Though the order of preference is maintained the value of Cl shows a higher value in Post tsunami only .The order of the abundance of cations is as follows Ca>Na>Mg>K in pre-tsunami and Na>K>Ca>Mg in post-tsunami. Na dominates the cations. Among the major ions the many fold increase of Na and Cl is supportive of the long residence time spent by the tsunami waters in these aquifers .There is no significant variation in the dissolved heavy metals in the aquifers subsequent to the tsunami implying leaching is very less from the polluted sources from soils after tsunami due to short stay of inundated water in the surface region . The SI of carbonate mineral in the samples for different periods, indicates that they are saturated to near saturated with Calcite (C) and Aragonite (A) . They are under saturated to near saturated with Magnesite (M). Dolomite (D) shows under saturation in the Pre-Tsunami samples but it shows super saturation during August. This may be due to increase of Mg concentration in the subsequent periods. It can be related that Ca is weakly correlated with other ions in January, which may be due to the removal of Ca from the system by the precipitation of calcium carbonate salts. The SID it still higher in August than in March, because of the dissolution of the salts which precipitated during March, thereby adding Magnesium into the system. There are two possibilities for the decrease of SIc in the system during January. Either one is due to the influence of the rainfall in Nov-Dec, which is the 2nd (retreating) monsoon period in these regions of India one is due to the long residence time of the in filtered water after the tsunami into this system.

Discussion The pH in these ground waters has slightly decreased after the tsunami whereas EC shoots up considerably reflecting the impact of the tsunami waters exists even after 3-8 months after the tsunami . Cl with an average of 1146 mgl-1 in post-tsunami shows an increased several folds indicating the long residence time of the tsunami water in the shallow aquifers .Bicarbonate with an average of 378 mgl-1 in post-tsunami reflecting the influence of sea water. Sulphate is generally derived from oxidative weathering of sulphide bearing minerals like Marcasite (which is abundant in these regions), but the sudden shoot of these ions that to above 500 mgl-1 is a clear indication of the role played by tsunami waters. Dominance of anions in the study area is as follows; Cl>HCO3>SO4 in both pre-tsunami and post-tsunami. Though the order of preference is maintained the value of Cl shows a higher value in Post tsunami only .The order of the abundance of cations is as follows Ca>Na>Mg>K in pre-tsunami and Na>K>Ca>Mg in post-tsunami. Na dominates the cations. Among the major ions the many fold increase of Na and Cl is supportive of the long residence time spent by the tsunami waters in these aquifers .There is no significant variation in the dissolved heavy metals in the aquifers subsequent to the tsunami implying leaching is very less from the polluted sources from soils after tsunami due to short stay of inundated water in the surface region . The SI of carbonate mineral in the samples for different periods, indicates that they are saturated to near saturated with Calcite (C) and Aragonite (A) . They are under saturated to near saturated with Magnesite (M). Dolomite (D) shows under saturation in the Pre-Tsunami samples but it shows super saturation during August. This may be due to increase of Mg concentration in the subsequent periods. It can be related that Ca is weakly correlated with other ions in January, which may be due to the removal of Ca from the system by the precipitation of calcium carbonate salts. The SID it still higher in August than in March, because of the dissolution of the salts which precipitated during March, thereby adding Magnesium into the system. There are two possibilities for the decrease of SIc in the system during January. Either one is due to the influence of the rainfall in Nov-Dec, which is the 2nd (retreating) monsoon period in these regions of India one is due to the long residence time of the in filtered water after the tsunami into this system. It was observed in nearby Palayar region that Sea water and the soil

leachate show similar SI to that of August. Hence it can be inferred that this is due to the impact of the tsunami and not due to the impact of rainfall. The correlation between the chief cation and anion were carried out. They indicate, during the pre-tsunami condition good correlation exist between Na and HCO3: Ca and Cl. Mg has good correlation with all ions. Ca, SO4 does not have correlation with any ions. During January Na develops positive correlation with Cl, Mg, K. Good positive correlation exist between Mg and HCO3. Ca, SO4 are not correlated with other ions present in the system. (Fig 2) During March good correlation exists between major cations Ca and Mg. Cl shows good correlation with Na, SO4 with K, Ca, Mg and Cl. HCO3 has good correlation between Na, Mg, Ca and Cl: Na, SO4 and Cl. All the ions are well represented in the correlation matrix .PCA was done by using the Varimax rotation. Factor analysis indicate that three prominent factors were extracted for pre-tsunami and January (post tsunami) and two for August and March. The first component of factor loading in pre-tsunami was represented by HCO3, Mg, and Na indicating the process of weathering. (Table 3) Table 3.

This may be due to the movement of neighboring saline watered down gradients or fast downward migration of saline water in that specific location. From our study we have inferred these processes might have been controlling the hydro geochemical changes of ground water after the tsunami. After the tsunami sea water entered the water table through the open wells or tube wells and got infiltered into the water table of the coastal alluvium during Jan 05.

INTRODUCTION Business is an economic institution organized and operated to provide goods and services to the society under the incentive of private gains. Many firms are providing goods and services to the society. The achievement of a sustainable tourism product requires the incorporation of tourism disaster planning and disaster response strategies into community and business frameworks. Despite the fact that disasters and their impacts are becoming frequent headlines in relation to tourism, few tourism businesses and tourism destinations are prepared to handle a disaster’s immediate- and longer-term impacts (Cassedy, 1991). In reality, tourism disaster planning seldom appears to be well conducted at the community level, and also to be rarely, if ever, carried out by individual tourism businesses (Cassedy, 1991). Little has been done by the tourism industry to understand how a disaster evolves once started, the typologies and anatomy of different disasters, how tourism is affected by and responds to disasters, and current disaster management strategies (Santana, 1999). Research is required to address these questions especially given that, with the exception of the airline sector, much of the tourism industry has belatedly begun to realise that disaster management should be a core aspect of its overall business structure (Beirman, 2002). Tourism is a service provided by the business firms. Tourism is the primary source of income for local communities at many tourist destinations. In countries like Thailand where tourism is the largest industry, it generates the highest proportion of foreign earnings. Most tourist destinations are located in coastal, mountain and forest areas and are thus often exposed to natural disasters that can have serious long-term impacts on local communities by threatening the

destination’s image, its tourism resources and its source of livelihood. Disasters at tourist destinations can also affect an entire country’s tourism trends, leading to heavy economic losses. When planning for disasters at tourist destinations, the question is not if, but when they will occur. It is difficult to predict the frequency of natural disasters: they could occur once in a lifetime, once every few years or seasonally. If tourism is a community’s primary source of income, then coping with potential disasters is pivotal to the community. To sustain tourism development and community livelihood, it is necessary to plan for the prevention, preparedness and mitigation of disasters at the destination. To develop sustainable tourism destinations and increase a community’s physical, economic and social wellbeing, ideas have evolved through sustainable tourism developmental approaches to consider not only tourists, but more importantly the physical, cultural, social and economic sustainability of host communities and tourism resources. Similarly, disasters are no longer seen as extreme events created by natural forces but as unresolved problems of development. Disaster Management practices have evolved from largely top-down relief and response to inter-sectoral risk management approaches. Some commonalities in current approaches to tourism planning and disaster management are: 1) they are more people-centered, 2) planning has become more inter-sectoral and 3) holistic development is their expected outcome. Despite common elements in their approaches and obvious benefits, Disaster Management has not been consciously integrated into tourism planning and development. The global call for sustainable development, and especially the sustainability of the world’s largest industry, demands their integration. However, there are institutional, capacity-building and management issues that need to be resolved before successful integration will be possible.

Tourism destinations all over the globe face the certainty of experiencing a disaster at some time. Despite this, few destinations have properly developed Disaster Management plans to help them cope with such eventualities. One reason for this is the limited amount of systematic research carried out in the field. This problem was addressed by drawing on the Disaster Management literature, combined with a more specific examination of tourism disaster strategies. Presented here are prerequisites and ingredients of effective planning towards producing a framework for analyzing and developing tourism Disaster Management strategies.

To sustain tourism development and community livelihood, it is necessary to plan for the prevention, preparedness and mitigation of disasters at the destination. To develop sustainable tourism destinations and increase a community’s physical, economic and social wellbeing, ideas have evolved through sustainable tourism developmental approaches to consider not only tourists, but more importantly the physical, cultural, social and economic sustainability of host communities and tourism resources. Similarly, disasters are no longer seen as extreme events created by natural forces but as unresolved problems of development. Disaster Management practices have evolved from largely top-down relief and response to inter-sectoral risk management approaches. Some commonalities in current approaches to tourism planning and disaster management are: 1) they are more people-centered, 2) planning has become more inter-sectoral and 3) holistic development is their expected outcome. Despite common elements in their approaches and obvious benefits, Disaster Management has not been consciously integrated into tourism planning and development. The global call for sustainable development, and especially the sustainability of the world’s largest industry, demands their integration. However, there are institutional, capacity-building and management issues that need to be resolved before successful integration will be possible.

Tourism destinations all over the globe face the certainty of experiencing a disaster at some time. Despite this, few destinations have properly developed Disaster Management plans to help them cope with such eventualities. One reason for this is the limited amount of systematic research carried out in the field. This problem was addressed by drawing on the Disaster Management literature, combined with a more specific examination of tourism disaster strategies. Presented here are prerequisites and ingredients of effective planning towards producing a framework for analyzing and developing tourism Disaster Management strategies.

accounting for one in every 12 jobs and transporting nearly 700 million international travellers per year. This last figure is expected to double by 2020. International tourism arrivals in developing countries have grown by an average of 9.5% per year since 1990, compared to 4.6% worldwide. The industry makes important contributions to developing country economies, representing the second largest source of foreign exchange after oil, although these countries currently have only a minority share of the international tourism market (approximately 30%). The aftershocks of the events of September 11th in the industry are impacting through a decline of tourists across the globe. In particular, destinations dependent on the American market e.g. some Caribbean islands, and where destinations are predominantly Muslim populations e.g. Indonesia. Where tourism generates more than 40% of GDP – small, low and middle income island nations in the Caribbean and Pacific – the impact of September 11th has confirmed some developing countries’ exposure to their dependency on tourism. Strategies to diversify and integrate their economies to protect livelihoods from the adverse shocks caused to tourism by political and natural disasters were already called for prior to September 11th and are even more imperative now.

Why are we thinking about the value of tourism enterprise interventions to poverty reduction? The present debate puts forward arguments for and against tourism’s potential for pro-poor growth compared to other sectors: 1. Its advantages are its size, labour intensity, potential for cross-sector linkages, and potential in countries and marginal areas with few other competitive exports. Tourism is consumed at the point of production, and the customer comes to the product – i.e. destination, providing potential linkages to formal and informal sector activities, often benefiting women working in petty trading (crafts, food). Tourism depends on natural capital – e.g. wildlife, land, and culture – that are assets that are owned by the poor, or who are gaining an increasing control over land where decentralisation and devolution of tenure are occurring. 2. Its disadvantages are that the industry is largely driven by foreign private sector interests and the economic benefits are not maximised due to a high level of foreign ownership. It is an industry that suffers from a high level of leakages (imports) and few linkages and imposes substantial non-economic costs on the poor, in terms of displacement, lost access to resources, and cultural and social disruption. The large-scale foreign companies have a comparative advantage when it comes to market access. Small entrepreneurs are often excluded from international marketing because of cost and inadequate institutional support.

Economic Impact The economic impact of tourism has been measured in terms of direct, indirect and induced effects using the quantitative tools of cost-benefit analysis, social cost-benefit analysis and the multiplier effect. 1. Direct effects arise out of currency inflows from foreign visitor expenditure in a host country, and outflows coming from expenditure abroad by residents. These are recorded by banks and businesses and can be measured. This will often include a tourism tax that is paid to either the local or national authorities, but not always reinvested in the local economy. This also includes those incomes that are directly affected by tourism and associated services. 2. Indirect effects arise as the direct expenditure is spent in other sectors of the economy. This is both what the tourist spends in other sectors while on holiday or business, and what those who are employed directly in tourism services, or associated services (transport, crafts) spend in other sectors. 3. Induced effects come from investment opportunities stimulated by tourism – e.g. land purchase for development, or industry linked to tourism e.g. sheepskin products in New Zealand and Australia. However, it is wrong to assume that there is a perfect correlation between the income generating effects of tourism and the creation of jobs. Aggregate figures can hide a variety of structural characteristics of tourism employment: the ratio of full to part-time employment; manual to skilled workers; female to male employees; ex-patriot to ethnic minority or indigenous workers.

management strategy for the tourism sector. According to Minister of Tourism and International Transport, Noel Lynch, this is being done in collaboration with the Central Emergency Relief Organisation and the Caribbean Disaster and Emergency Response Agency. His comments came at the Inter-American Tourism and Recreational Facilities Security (ITRS) Workshop at the Amaryllis Beach Resort yesterday morning hosted by the Inter-American Committee Against Terrorism (CICTE). He stated that in addition to developing an overall framework for addressing various hazards, the Ministry has been collaborating with the private sector and law enforcement community with regard to consequence management in the context of terrorism and the execution of a series of training initiatives targeting both public and private sector security officials. Within the context of multi-hazard disaster management, however, manmade disasters such as terrorism and bio-terrorism and health related threats such as epidemics must also be borne in mind by the tourism industry and measures put in place to address such, to ensure the sustainability of the industry, Minister Lynch said. He maintained that the Government is committed to the creation and implementation of a sustainable tourism development programme that fosters a safe and secure environment for visitors and the host populations alike. Additionally, he said that the Ministry has also established a Tourism Emergency Management Committee (TEMC) and a Tourism Emergency Operations Centre (TEOC). The TEMC he said, plans and co-ordinates the tourism sectors response during emergencies, while the latter will mirror the operations of the National Emergency Operations and will be a command centre from which persons will jointly co-ordinate the management of disasters in the tourism context. He also revealed that the Ministry has collaborated with the Royal Barbados Police Force and stakeholders in the industry to address the area of safety and security codes of practice for all tourism establishments, and he said initial draft standards are in the process of being developed. Speaking to the ITRS workshop, he said that it provides the insight needed to ensure that there are no hiccups with respect to security during the Cricket World Cup (CWC) matches. Through the workshop, he said, security personnel will be equipped to handle security challenges with renewed confidence and efficiency. However, he said that the course is not just about security for CWC, but security for the region. As such, he said that the Government of Barbados is committed to the decision to implement the CARICOM visa, to ensure the highest level of security. Those initially objected to the visa let me say for the record, the visa was implemented not only to protect the locals of these countries but to seriously protect those visiting us as well coming from developed countries. In addition, he said that in the case of Barbados there have been no significant increases in cancellations because of the implementation of the visa and he said even if a loss is recorded, it would be more than worth it, for the people of the region to remain safe.

Disaster Management

Tourism and Disaster Management, Lakshadweep as an Example Surrounded by vast ocean islands of Lakshadweep are open to storms and cyclones. Natural Calamities like earthquake, flood, and drought have not occurred in Lakshadweep so far. One of the earliest natural calamities recorded was the great storm that struck the islands in April 1847. It commenced in Kalpeni about 8 pm. on 15th April, passed on to Andrott and finally reached Kiltan after devastating these two islands. All the houses in Kalpeni were damaged or washed away. Out of the population of 1682, 246 were drowned or washed away in Kalpeni. In 1891 a violent storm burst upon Kavaratti Island causing considerable damage to coconut trees. The storm caused damage in Agatti and Amindivi group of Islands also. Kalpeni Island was hit by a severe cyclone on 1st December 1922. The waves washed completely over the narrow northern end and the sea poured across the island into the lagoon. There was no loss of life. The cyclone was felt in other islands also. Another major storm that struck the islands occurred in 1941. In 1963 and 1965 also major calamity occurred causing considerable loss of properties in Andrott, Kalpeni, Agatti and Kiltan. There was no loss of life. The last cyclone occurred in 1977 in Kalpeni and Andrott without causing any loss of life. A large number of coconut trees were uprooted and some houses were also damaged. There is no international organisation/society/agency engaged in the field of natural disaster prevention and reduction in Lakshadweep. The revenue Department of Lakshadweep Administration is designated as the nodal department for the whole Union Territory. Early warning system: Cyclone warning to Lakshadweep is provided from the Area Cyclone Warning Centres at Chennai and Trivandrum. A monitoring Cell functions in the Collectorate at Head Quarter Island Kavaratti, which immediately transmits such messages to all islands. The TV network also plays vital role. Communication net work of BSNL, Naval detachment, Interstate Police Wireless, Lakshadweep Police Wireless, IR Battalion Wireless, NIC, etc. will be fully utilized for warning and for communication. All the Development Departments are associated under the Disaster Management Plan (including Public Works Department and Electricity Department, consisting of respective engineers, Port, Shipping & Transport Department, Telecommunication-BSNL, Panchayats etc.) The Administration is also exploring the possibility of setting up a Bharatiya Search and Rescue Team for the Union Territory consisting of Lakshadweep Police, India Reserve Battalion, Lakshadweep Fire Force, Marine Police Force (after its operational commencement).

Disaster Management

at ensuring that everyone understands what is expected of them. Ingredients of the tourism Disaster Management planning process and its outcomes should include: Risk Assessment: An assessment of potential disaster situations and their relative occurrence probability is an essential first step. This should involve an historical analysis of natural disasters in the region, along with a scanning of the current and emerging environment and alternative scenarios. Prioritization: A cascaded strategic priority profile (CSPP) needs to be prepared, with a ranking of tasks and activities to be undertaken in response to high risk events identified in the previous step. This also involves the prioritization of actions and the articulation of these across organizations so that a coordinated response can be developed. It must be recognized that tourists are vulnerable in unfamiliar surroundings and their safety must be prioritized. Protocols: A clearly enunciated set of protocols to ensure that the activities of emergency agencies, tourism authorities and operators are properly coordinated, needs to be established and accepted by all parties. Community Capabilities Audit: An assessment of community capacity to cope with specific disasters needs to be carried out so that the appropriate level of emergency relief from external sources can be determined. This should involve an inventory of the relevant physical, financial and organizational resources of the community. Disaster Management Command Centre: A properly resourced Disaster Management command centre, as the focal point for the Disaster Management team’s operations, is essential. The location and procedures for setting up this facility must be specified in the plan. Media and Monitoring Activities: A media communication strategy, with an early establishment of a centralized source, is necessary to ensure that misleading and contradictory information is not disseminated, and to support response coordination. The media often plays a central role in tourism disaster situations, both in terms of providing important information to tourists during the emergency and in the recovery stage when other sectors of the industry and the consuming public need to be informed about the restoration of services. Systems for monitoring disaster impact, and providing reliable information on safety and the status of tourism services, are therefore needed. Warning Systems: Once a disaster strategy is in place, the conditions necessary to activate it must be specified, along with the types of hazard for which it is designed. Systems for communicating warnings are also important. Flexibility: Certain elements of disaster strategies are applicable to all types of emergencies. However, the exposure of some destinations to certain disasters is greater than others and these must be identified so that responses to specific impacts and requirements of high-risk events can be planned. Some flexibility is also important, as the sequence of necessary actions may vary between different types of emergency. Flexibility is also required because it may be necessary for some organizations to perform functions they do not normally carry out.

Involvement, Education and Review: The effectiveness of disaster response and recovery plans will be limited unless those who are required to implement them are directly involved in their development. Organizations and communities need to be informed about the strategy, which should be periodically reviewed in light of reactions to it and new developments. Disaster strategies therefore need to be continuously updated and refined to ensure that new information and organizational changes are taken into account. In particular, post-disaster debriefings are important so that lessons can be learned from experience. When tourists evacuate before or after a disaster, there are both behavioral similarities and dissimilarities to patterns documented for residential populations. For example, threat denial is the prevailing initial response for both populations. Warning sources differ significantly, however, with tourists often reporting the receipt of threat information from lodging staff, other tourists and employees of nearby businesses and frequently these sources neutralize emerging threat perceptions resulting in delay and argument. Many tourists take refuge in public shelters and report various sources of dissatisfaction. Most frequently noted were: 1) feared shelter was unsafe, 2) inadequacies with facility (e.g., blocked toilets), 3) excessive crowding, 4) staff-related social factors (e.g., poor management), 5) food inadequacies, 6) peer-related social factors (e.g., unruly children), 7) threat information not available, and 8) shelter location (e.g., hard to find). Conversely, many described their satisfaction with their shelter experience in terms that paralleled these same themes. There is a substantial gap in the expectations of customers and managers regarding emergency preparedness. For example, consider this questionnaire item: “Despite some public relations efforts, I suspect that managers of most business firms have little or no commitment to disaster evacuation planning.” Most managers disagreed (63 percent) whereas one-half of the tourists and business travellers agreed. Inadequate disaster preparedness results in higher levels of employee dissatisfaction. Acute tensions between work and family priorities were described by one-third of the 406 employees interviewed. Three-fourths, however, said that business managers should give more consideration to potential tensions between work and family in their evacuation plans. Of special importance to thirty percent was that they were not paid during the evacuation time. Failure to provide leadership on these and other issues contributed to judgments of dissatisfaction which lingered long after recovery.

Disaster Management

Recommendations Customer Perspectives. Tourist business managers should: 1) be proactive with warnings, 2) keep customers informed with updates, 3) have a disaster plan, 4) have a hazard brochure and disaster evacuation plans in the room, 5) be available so that guests know who’s in charge, 6) train staff, 7) be prepared to help guests find emergency shelter, 8) recognize that tourists are not familiar with either the area or the threat, and 9) be prepared to provide food and other emergency supplies. 1) 2) 3) 4) 5) 6) 7)

Employee Perspectives. Tourist business managers should: communicate better, close sooner, provide employee assistance when needed, do more preparedness, have more staff to implement protective actions, establish return procedures, and provide pay for employee time-off during disaster-induced evacuations.

CONCLUSION The catastrophic vulnerability represented by the tourism industry requires a significant new investment in disaster preparedness and training. It should be available within existing university-based management curricula and through specialized seminars for those already in the workforce. The scope of tourism Industry in India very high and the local community can play an important role in managing any disasters by tourism activities and through sustainable approach we can make a healthy environment.

INTRODUCTION Tsunami is a wave of high energy, which is generated by an earthquake or landslide in the sea. The Tsunami wavelengths and their periods depend on the generating mechanism and the magnitude of the source event. The period of the tsunami waves may range from 5 to 90 minutes. The length of the wave crests of a tsunami can be more than thousand km and the waves may be from a few kilometers to more than a hundred kilometers apart as they travel across the ocean. The speed of tsunami waves increases with the depth of the sea and may exceed 800 km/hr. The areas within 1.6 km of the shoreline and about 15 m above the sea level face the greatest risk during a tsunami. Seawater can intrude over land filling wells and ponds, and percolate into the subsurface. Conditions can get worse if seawater penetrates the aquifer. It may take years or decades for the seasonal rainfall to wash the soil/aquifer/rocks clean, or much longer. In some cases, a river channel can provide a passage for a tsunami bore to rush through, allowing it to flood tremendous tracts of land far inside from the shoreline. This paper examines the adverse consequences of the December 26, 2004 tsunami on the groundwater resources of the Indian coast and proposes a remediation framework for similar emergency situations. The specific interest within the objective of this study has been also to carry out an assessment of hydrogeological characteristics and risk to coastal aquifers in the districts of Tamilnadu in southeastern India.

struck the active subduction corridor along the eastern margin of the Indian lithosphere off the coast of Sumatra in Indonesia. It took the tsunami waves about 2 hours to reach the Indian coast. The wave reached Andaman, on the east coast of Sri Lanka and Tamilnadu and up to Orissa, further north along the east coast. On reaching shallow waters along the coastline, the energy of the deep sea waves is transformed into very forceful tidal waves of great height (10–30 m) causing vast devastation. Wave arrival times obtained from coastal tide gage and satellite altimetry records for the Indian Ocean are used to delineate the source region for the December 26, 2004 Sumatra tsunami. Findings define a curved, 250-km wide, 1000-km long tsunami source region centered over the Sunda Subduction Zone, which closely matches the seismic source estimated from broadband geophysical data. Imbedded in this general region are ‘‘hot spots’’ associated with the southern fast-slip and northern slow-slip domains which served as distinct source areas for the destructive waves that inundated the coast of the Indian Ocean. Citation. (Fine, I. V., A. B. Rabinovich, and R. E. Thomson ,2005). The Sumatra-Andaman Island mega thrust earthquake of 00:59 UTC 26 December 2004 was first estimated as Mw = 9.0 and later upgraded to Mw = 9.3 based on the analysis of the normal modes of the Earth (Stein and Okal, 2005). This was the second largest earthquake ever recorded. Tsunami waves generated by the earthquake were responsible for over 250,000 dead and missing, and left millions homeless and displaced in areas bordering the Indian Ocean. Tsunami records from a number of tide guages in the Indian Ocean [Merrifield et al., 2005] are of sufficiently high quality and resolution for accurate estimation of tsunami arrival times. The tsunami was also recorded by the Jason1 and Topex/Poseidon satellites [Gower, 2005; Smith et al., 2005]. Data from the Eastern and Central Indian Ocean, which is close to the source area, is critical for examination of the event and its regional impact. In this study, we use inverse wave-tracing to delineate the generation region for the Sumatra Tsunami. Results are based on Tsunami arrival times from tide gage and satellite altimetry records and on wave propagation speeds derived using high resolution 1-min (1.85 km) bathymetric data.

we estimated the observed propagation time from the beginning of the earthquake to the arrival at the recording site (Table 1). The source delineation is limited by the accuracy of the estimated arrival times, by the bathymetry data used in the numerical simulations (1-min GEBCO topographic data [British oceanographic Data Centre, 2003]), and by non-linear and dispersive effects. As shown in Figure 2a, the aftershock region following the December 26, 2004 Sumatra Earthquake extends from 2_ N to 15_ N along the Indo-Andaman plate boundary. Although there have been several major thrust earthquakes in this region in the past, the Mw = 9.3 earthquake of December 2004 has no historical precedent [Bilham et al., 2005]. The distribution of aftershocks indicates that the primary rupture accompanying the main shock took roughly 10 min to propagate 1300 km northward from the epicenter near 3.3_ N, corresponding to an average northward propagation speed of _2 km_s_1 [Stein and Okal, 2005]. The stations used in our first-wave arrival time analysis fall into four groups (Table 1): ‘‘northwestern’’ (stations 1–2); ‘‘western’’ (3–8); ‘‘southern’’ (9); and ‘‘eastern’’ (10). The first waves to arrive at gages in the western group followed similar wave paths. As a consequence, computed inverse wave front contours closely parallel one another, thereby defining approximately the same western boundary for the source region. Spatial separations are within the errors of our simulations (inaccuracies in the estimated arrival times are about 4–6 min). For all six sites, intersection points for the leading wave-front curves are co-located above the Sumatra Trench Table 1. Tsunami Properties Estimated From Coastal Tide Gage Records in the Indian Ocean No. Station Country Coordinates. Wave-retracing based on the tide gage station in the Cocos Islands (9) locates the southern boundary of the source, with the Tsunami wave front coincident with the southern edge of the aftershock region .The northwestern stations Vishakhapatnam (1) and Chennai (2), on the east coast of India, help define the long-axis extent of the Tsunami source. Following corrections for delays due to the finite rupture speed of 2 km_s_1 and nonlinear effects on wave propagation speed for the shallow- water region off the eastern coast of India, wave retracing confirms that the northernmost end of the source region extended to at least 10–11_N, consistent with recent estimates based on analysis of the earthquake-induced eigen oscillations [Stein and Okal, 2005], Global Positioning System (GPS) measurements [Vigny et al., 2005], and hydro acoustic data an original image of the seismic rupture of the Sumatra Mw = 9.0 using PMCC from seismic and hydro acoustic small array (Guilbert et al 2005). The first recorded waves at stations 1–9 were crests (positive waves) due to a rapid uplift on the western side of the source area. In contrast, the first waves recorded on the coasts of Thailand and Indonesia were troughs (negative waves), indicating an abrupt subsidence on the eastern side of the source region. Because of the relatively poor resolution of gages in Thailand and Indonesia, the only reliable estimate for the arrival times in this region is from the sounder on the yacht ‘‘Mercator.’’ According to this record, the calculated inverse-wave Table 1: Tsumani Properties Estimated from Coastal Tide Gage Records in the Indian Ocean.

we estimated the observed propagation time from the beginning of the earthquake to the arrival at the recording site (Table 1). The source delineation is limited by the accuracy of the estimated arrival times, by the bathymetry data used in the numerical simulations (1-min GEBCO topographic data [British oceanographic Data Centre, 2003]), and by non-linear and dispersive effects. As shown in Figure 2a, the aftershock region following the December 26, 2004 Sumatra Earthquake extends from 2_ N to 15_ N along the Indo-Andaman plate boundary. Although there have been several major thrust earthquakes in this region in the past, the Mw = 9.3 earthquake of December 2004 has no historical precedent [Bilham et al., 2005]. The distribution of aftershocks indicates that the primary rupture accompanying the main shock took roughly 10 min to propagate 1300 km northward from the epicenter near 3.3_ N, corresponding to an average northward propagation speed of _2 km_s_1 [Stein and Okal, 2005]. The stations used in our first-wave arrival time analysis fall into four groups (Table 1): ‘‘northwestern’’ (stations 1–2); ‘‘western’’ (3–8); ‘‘southern’’ (9); and ‘‘eastern’’ (10). The first waves to arrive at gages in the western group followed similar wave paths. As a consequence, computed inverse wave front contours closely parallel one another, thereby defining approximately the same western boundary for the source region. Spatial separations are within the errors of our simulations (inaccuracies in the estimated arrival times are about 4–6 min). For all six sites, intersection points for the leading wave-front curves are co-located above the Sumatra Trench Table 1. Tsunami Properties Estimated From Coastal Tide Gage Records in the Indian Ocean No. Station Country Coordinates. Wave-retracing based on the tide gage station in the Cocos Islands (9) locates the southern boundary of the source, with the Tsunami wave front coincident with the southern edge of the aftershock region .The northwestern stations Vishakhapatnam (1) and Chennai (2), on the east coast of India, help define the long-axis extent of the Tsunami source. Following corrections for delays due to the finite rupture speed of 2 km_s_1 and nonlinear effects on wave propagation speed for the shallow- water region off the eastern coast of India, wave retracing confirms that the northernmost end of the source region extended to at least 10–11_N, consistent with recent estimates based on analysis of the earthquake-induced eigen oscillations [Stein and Okal, 2005], Global Positioning System (GPS) measurements [Vigny et al., 2005], and hydro acoustic data an original image of the seismic rupture of the Sumatra Mw = 9.0 using PMCC from seismic and hydro acoustic small array (Guilbert et al 2005). The first recorded waves at stations 1–9 were crests (positive waves) due to a rapid uplift on the western side of the source area. In contrast, the first waves recorded on the coasts of Thailand and Indonesia were troughs (negative waves), indicating an abrupt subsidence on the eastern side of the source region. Because of the relatively poor resolution of gages in Thailand and Indonesia, the only reliable estimate for the arrival times in this region is from the sounder on the yacht ‘‘Mercator.’’ According to this record, the calculated inverse-wave Table 1: Tsumani Properties Estimated from Coastal Tide Gage Records in the Indian Ocean.

As with the tide gage records for stations 1to 9, the leading wave measured by satellite was a 50 cm high wave crest (corrected for more persistent oceanic features such as eddies using altimeter data from the tracks before and after the event [data from Smith et al., 2005]. Using the times and positions for the leading edge of the first ‘‘south’’ wave (Sa) along the satellite tracks (Table 2), inverse wave tracing yields contours which generally coincide with one another and with contours calculated from tide gage data. These results position the southwestern border of the source region close to the main shock epicenter. Locating the northern boundary of the source region proved more problematic. The leading edge of the advancing Tsunami cannot be precisely pinpointed along the northern sections of the satellite tracks because the lead wave struck the coast a few minutes before the satellites passed over (Figure 1). Consequently, we have had to turn to the arrival times for the first wave crest (Table 2), which identifies the source region for the maximum tsunami waves. The ‘‘northern’’ peak in the Jason-1 and Topex/Poseidon records had a height of _40 cm. According to Figure 2b, the inverse Tsunami travel time lines for the northern peak (Np) pass through the northern part of the rupture zone between 9_ to 13_N. The eastern part of this particular zone cannot be the source for this peak because it was a subsidence region, and we can exclude the Andaman Islands because tsunamis are not Figure 3.

We note that, if the leading edge of the satellite-detected Tsunami was actually that of the leading wave immediately after reflection from the Myanmar coast, the northern source region would need to be extended even further to the north.

front (10) for the leading tsunami wave coincides with the border of the aftershock zone extending northward from the Island of Sumatra. As with the tide gage records for stations 1to 9, the leading wave measured by satellite was a 50 cm high wave crest (corrected for more persistent oceanic features such as eddies using altimeter data from the tracks before and after the event [data from Smith et al., 2005]. Using the times and positions for the leading edge of the first ‘‘south’’ wave (Sa) along the satellite tracks (Table 2), inverse wave tracing yields contours which generally coincide with one another and with contours calculated from tide gage data. These results position the southwestern border of the source region close to the main shock epicenter. Locating the northern boundary of the source region proved more problematic. The leading edge of the advancing Tsunami cannot be precisely pinpointed along the northern sections of the satellite tracks because the lead wave struck the coast a few minutes before the satellites passed over (Figure 1). Consequently, we have had to turn to the arrival times for the first wave crest (Table 2), which identifies the source region for the maximum tsunami waves. The ‘‘northern’’ peak in the Jason-1 and Topex/Poseidon records had a height of _40 cm. According to Figure 2b, the inverse Tsunami travel time lines for the northern peak (Np) pass through the northern part of the rupture zone between 9_ to 13_N. The eastern part of this particular zone cannot be the source for this peak because it was a subsidence region, and we can exclude the Andaman Islands because tsunamis are not Figure 3.

We note that, if the leading edge of the satellite-detected Tsunami was actually that of the leading wave immediately after reflection from the Myanmar coast, the northern source region would need to be extended even further to the north. Wave-retracing based on the southern satellite altimetry peak (Sp) yields inverse contours that pass through the southern part of the aftershock area from NW to SE The resulting inverse propagation contours derived from the two satellite tracks are mutually consistent. They fall close to the plate boundary and agree well with the source of the principal tsunami defined by Bilham et al. [2005].

Indian Scenario Palanivelu et al (2006) has studied the ground water quality assessment in the Tsunami-affected coastal areas of Chennai, located in the 250 Km north of the study area. They have studied the TDS values and observed that at a few locations away from the sea there showed an increase of TDS from May to September 2005. The increase may be due to insufficient rainfall in Chennai during this period till September, which in turn shows that the southern part of the coastal Chennai is highly contaminated compared to the northern part. TDS levels observed after Tsunami were within the range as observed during September 2004. Thus their study reveals that the recorded TDS values over time indicate that there is no major impact of the Tsunami on water quality. They concluded that the groundwater quality has deteriorated due with lack of sufficient rainfall leading to sea-water intrusion that is reflected in high TDS and chloride content of the samples. Muralideran et al (2005) has studied the imprint of 26 December 2004 Sumatra earthquake in the aquifers of the Hyderabad granite pluton. They explained that the earthquake had induced hydrological changes caused by changes in hydrostatic pressure due to earthquake-induced changes in crustal volumetric strain. The effects before and after the Sumatra earthquake were clearly registered in hydrographs of wells located over Hyderabad granite pluton. They presented the micro-level impressions registered in hydrograph of a deep bore-well located in the National Geophysical Research Institute (NGRI) campus, Hyderabad, supported with records of other bore wells located more than ~100 km away from the NGRI well site. The signature of Tsunami on water level was well registered by a quiescent prelude followed by turbulence. The quiet period between08:44:40 and 09:19:20 is the first of its kind in the hydrograph record so far gathered. It coincides with recession of sea observed prior to the Tsunami. Perturbations observed between 09:19:20 and 10:00:40 h coincide with the hit time of tsunami on the east coast. According to the tidal records of Survey of India and its notification, the Tsunami that hit at Visakapatinam by 09:10:00 h was considered for analysis as it is near Hyderabad compared with other tidal stations. The disturbance observed on the hydrograph lags nearly by 10 min with the hit time of the Tsunami. They observed rise in water level from 25 December 2004 to 2 January 2005, and a decline beyond 2 January during non monsoon period, collectively indicates the effect of the Sumatra main earthquake and aftershocks. The rise in water level was about 90 mm. In order to confirm their observation, continuous water-level data of forty wells in the Mehaboobnagar district was observed. Andhra Pradesh was also collected data from the State Groundwater Department and analyzed it. Similar a rises in water levels during the that period were also observed by them, in only four out of forty bore-wells near the coast. We have also identified that the Tsunami inundated region ranges in these regions from 0.5 to 1 Km from the coast in Tamilnadu (Fig 2).From our detailed

study we have inferred the processes responsible for changes in water quantity and quality after the Tsunami in the shallow ground waters of this region which have been controlling the hydrochemical changes of ground water after tsunami. Our study futher elaborate of the process as being responsible for the present day ground water quality used for drinking water .After the Tsunami sea water entered the water table through the open wells or tube wells and the entrapped water got infiltered into the water table of the coastal alluvium during Jan 05, later high temperature in the summer months might have resulted in the formation of salt precipitates near the surface or in pore spaces and subsequent dilution in the end of March 05 by sparse rain. After precipitation and dissolution, salt leached out from the surface to the shallow groundwater zones enhancing the EC and TDS of the groundwater of August 05. Thus the impact of direct infiltration or direct mixing of Tsunami waters on these ground waters in coastal areas of Tamilnadu has relatively lesser effect than the subsequent precipitation and dissolution of salts formed by the entrapped sea water which happened after the Tsunami event. Wave re-tracing based on the initial Tsunami arrival times defines the general source region for the 2004 Sumatra tsunami as a curved, 250-km wide, roughly 1000-km long earthquake rupture segment centered over the Sunda Subduction Zone. The next step was to identify locations of more localized, imbedded source areas responsible for the major wave destruction in the Indian Ocean. The re-traced wave fronts from the peak-wave satellite track position Sp (Table 2) and from the peak-wave arrival contours estimated from the western (3–8) group of tide gages intersect at approximately 4.5 0 N, 94 0 E , identifying this as the likely generation region for the destructive Tsunami waves.

study we have inferred the processes responsible for changes in water quantity and quality after the Tsunami in the shallow ground waters of this region which have been controlling the hydrochemical changes of ground water after tsunami. Our study futher elaborate of the process as being responsible for the present day ground water quality used for drinking water .After the Tsunami sea water entered the water table through the open wells or tube wells and the entrapped water got infiltered into the water table of the coastal alluvium during Jan 05, later high temperature in the summer months might have resulted in the formation of salt precipitates near the surface or in pore spaces and subsequent dilution in the end of March 05 by sparse rain. After precipitation and dissolution, salt leached out from the surface to the shallow groundwater zones enhancing the EC and TDS of the groundwater of August 05. Thus the impact of direct infiltration or direct mixing of Tsunami waters on these ground waters in coastal areas of Tamilnadu has relatively lesser effect than the subsequent precipitation and dissolution of salts formed by the entrapped sea water which happened after the Tsunami event. Wave re-tracing based on the initial Tsunami arrival times defines the general source region for the 2004 Sumatra tsunami as a curved, 250-km wide, roughly 1000-km long earthquake rupture segment centered over the Sunda Subduction Zone. The next step was to identify locations of more localized, imbedded source areas responsible for the major wave destruction in the Indian Ocean. The re-traced wave fronts from the peak-wave satellite track position Sp (Table 2) and from the peak-wave arrival contours estimated from the western (3–8) group of tide gages intersect at approximately 4.5 0 N, 94 0 E , identifying this as the likely generation region for the destructive Tsunami waves.

In summary, the tide gage (Table 1) and satellite (Table 2) data reveal two well-defined zones that include most of the crossings (the most probable source areas) of the inverse wave-propagation fronts for wave crests: (1) a ‘‘southern source’’ located west of North Sumatra (2.5_– 5.3_N), close to the main epicenter; and (2) a ‘‘northern source’’ immediately to the south of the Andaman Islands (9.0_–10.2_N). This ‘‘dual source’’ concept is supported by estimates of the surface deformation measured in this region by GPS [Vigny et al., 2005] and by independent conclusions provided by analyses of hydro acoustic and low-frequency seismic information from two small research arrays in Diego Garcia and Thailand (Guilbert et al., 2005). The southern source region is coincident with the ‘‘fast slip’’ area estimated from body waves [Stein and Okal, 2005; Ji, 2005]. According to our computations, this zone is responsible for the generation of the major tsunami waves that struck Sri Lanka, the Maldives and the coasts of East and South Africa. The ‘‘peak’’ source had a spatial extent of about 350 km. When findings for the leading waves are included, the entire southern source is estimated to be 600–650 km long, in agreement with seismological estimates [Stein and Okal, 2005; Bilham et al., 2005; Ji, 2005]. The northern Tsunami source region coincides with the area of slow slip [Stein and Okal, 2005]. This weaker source region was responsible for the somewhat smaller first waves that reached the coasts of Bangladesh, Myanmar, and eastern India. When both segments are combined, the Tsunami source region derived from the first-wave arrival times is more than 1000 km long. It was because of this large spatial extent that low frequency wave components were so prevalent in the Tsunami waves recorded throughout the world ocean. Managing the impact of Tsunami The nations of the region and several international organizations are working together to develop an effective tsunami early warning system that will reach the entire regional community, particularly the most vulnerable groups. What is known about past and future coastal change can be applied to define a reference line showing where the shoreline is anticipated to be, for example, by 2050. Detailed aerial photographs could be prepared reach by reach for all of the region’s shoreline, showing conditions as they were before and after the tsunami. A reference line could be drawn on such photographs showing the mean high water mark anticipated by the 2050 median projection for a sea level rise of 30cm made by the Intergovernmental Panel on Climate Change (IPCC). This reference line should be modified by other tectonic and coastal data affecting anticipated coastal change in specific areas. Where information is available, data on the anticipated effect of historical trends in erosion and accretion to 2050 and the inland extent of flooding in past storms should also be integrated into estimates of the future position of shorelines. A recommended construction setback line should be established by each government a set distance and/or elevation inland of the reference line. The

area seaward of the setback line should be designated as a strictly enforced “nobuild” zone. It is essential that such setbacks are incorporated into the existing regulatory system and are applied equitably to the wealthy and the poor. On low-lying shorelines with little topographical relief, practical disaster preparedness plans should be developed and tested that feature speedy evacuation of people to protected shelters. The width of the no-build zone determined by the setback should be greater in as-yet-undeveloped shores than in already urbanized areas. Designate setback lines with permanent on-site markers and should enforce them uniformly as a regulatory measure. Exceptions for building structures seaward of the setback line should be granted only where required to support such water-dependent activities as fishing and navigation (not tourist facilities or permanent settlements). Where such exceptions are granted, structures should be temporary or built to withstand flooding by strengthened structural members and elevated first floors that permit flood waters to flow through unimpeded. Attention should be given to the impact of such structures on adjacent coastal areas, and mitigation actions taken. REFERENCES Abe, K. (1973), Tsunami and mechanism of great earthquakes, Phys.

It is essential that such setbacks are incorporated into the existing regulatory system and are applied equitably to the wealthy and the poor. On low-lying shorelines with little topographical relief, practical disaster preparedness plans should be developed and tested that feature speedy evacuation of people to protected shelters. The width of the no-build zone determined by the setback should be greater in as-yet-undeveloped shores than in already urbanized areas. Designate setback lines with permanent on-site markers and should enforce them uniformly as a regulatory measure. Exceptions for building structures seaward of the setback line should be granted only where required to support such water-dependent activities as fishing and navigation (not tourist facilities or permanent settlements). Where such exceptions are granted, structures should be temporary or built to withstand flooding by strengthened structural members and elevated first floors that permit flood waters to flow through unimpeded. Attention should be given to the impact of such structures on adjacent coastal areas, and mitigation actions taken. REFERENCES Abe, K. (1973), Tsunami and mechanism of great earthquakes, Phys.

By definition, there cannot be a perfect ideal system that prevents damage, because then it would not be a disaster. It has to suffocate our ability to recover. Only then can it be called a ‘disaster’. Disasters are not totally discrete events. Their possibility of occurrence, in time, place and severity of the strike can be reasonably and in some cases accurately predicted by technological and scientific advances. It has been established that there is a definite pattern in their occurrence and hence we can to some extent reduce the impact of damage though we cannot reduce the extent of damage itself. This demands the study of Disaster Management in a methodical and orderly way. Recognizing the challenges which need proper attention and their inclusion at different stages of a Disaster Management cycle are imperative in this paper.

Stages in Disaster Management

Stages in Disaster Management

There are five important phases of disaster management: disaster prevention, disaster mitigation, disaster preparedness, emergency management, and disaster recovery (Fig.1.1.). Of these, disaster prevention, disaster mitigation, and disaster preparedness constitute the pre-disaster planning phase. Pre-disaster planning is the process of preparing in advance, to meet a future disaster. Disaster prevention is the action taken to eliminate or avoid harmful natural phenomena and their effects. Disaster Management is the action that deals with reducing human suffering and property loss. Disaster preparedness encompasses those actions, which are taken to limit the impact of natural phenomena by structuring response and establishing a mechanism for effecting a quick and orderly reaction. Emergency management covers responding to disasters by various organizations, providing many services that need to be mobilized at a moment’s notice, and functioning for an indeterminate period in a coordinated manner under stressful and difficult circumstances. People may be demobilized after the emergency has abated. The ability of an agency, or a group of agencies, to manage emergencies, rather than just react to crises, is critically dependent on the availability and flow of real time and archived information from monitoring systems, thematic databases, and decision support systems that are linked through national networks. Disaster recovery is the last phase of Disaster Management and is concerned with providing relief after the disaster has struck. It deals with providing food and shelter to the disaster victims, restoring normal conditions and providing financial and technical assistance to rebuild. India’s Disaster Proneness The Indian subcontinent is characterized by unique geodynamics, typical monsoon behaviour, flood prone river basins co-existing with semi arid and arid regions and long coastlines and is amongst the world’s most disaster-prone areas. Fifty four per cent of the Indian land mass is vulnerable to earthquakes, Eight per cent is vulnerable to cyclones and more than Five per cent is vulnerable

By definition, there cannot be a perfect ideal system that prevents damage, because then it would not be a disaster. It has to suffocate our ability to recover. Only then can it be called a ‘disaster’. Disasters are not totally discrete events. Their possibility of occurrence, in time, place and severity of the strike can be reasonably and in some cases accurately predicted by technological and scientific advances. It has been established that there is a definite pattern in their occurrence and hence we can to some extent reduce the impact of damage though we cannot reduce the extent of damage itself. This demands the study of Disaster Management in a methodical and orderly way. Recognizing the challenges which need proper attention and their inclusion at different stages of a Disaster Management cycle are imperative in this paper. Stages in Disaster Management There are five important phases of disaster management: disaster prevention, disaster mitigation, preparedness, emergency Fig.disaster 1.1 : Disaster Management Cyclemanagement, and disaster recovery (Fig.1.1.). Of these, disaster prevention, disaster mitigation, and disaster preparedness constitute the pre-disaster planning phase. Pre-disaster planning is to floods. Over 40 million Hectares are prone to Floods. Nearly 3 lakh sq. km the process of preparing in advance, to meet a future disaster. Disaster prevention are at risk of Cyclones. Between 1990 and 2000 an average of about 3,400 is the action taken to eliminate or avoid harmful natural phenomena and their people lost their lives annually. About 3 crore people are affected by Disasters effects. Disaster Management is the action that deals with reducing human every year. suffering and property loss. Disaster preparedness encompasses those actions, With such estimations, can we lay back and pronounce that we are safe? which are taken to limit the impact of natural phenomena by structuring response No. Losses from disasters have increased dramatically over the past few decades. and establishing a mechanism for effecting a quick and orderly reaction. The loss of population and property is always on the rise. This is because of Emergency management covers responding to disasters by various organizations, changes in the pattern of hazard occurrence and from increased vulnerability of providing many services that need to be mobilized at a moment’s notice, and a growing population. On the basis of geographic and climatic considerations, functioning for an indeterminate period in a coordinated manner under stressful India can be divided into 5 Zones according to its disaster proneness to natural and difficult circumstances.

be built into a developmental process and investment in management is much more cost effective than the expenditure on relief and rehabilitation. Disaster Management now occupies an important place in the country’s policy framework covering institutional mechanisms, disaster prevention strategies, early warning systems, disaster mitigation, preparedness in response in developing human resources. These elements, along with environmental protection and sustainable development, are closely related. The roadmap hence prepared also involves agencies at the National, State and District levels. Hence, emphasise on disaster prevention, mitigation and preparedness are better than disaster response in achieving the goal sustained development. The Government of India has adopted management and prevention as essential components of their developmental strategy. The tenth “Five year Plan” documents a detailed chapter on disaster management. Core groups and committees for earthquakes, cyclones and floods have already been created. A Disaster Risk Management Programme has been taken up with the assistance from UNDP, USAID and the European Union in 169 most hazard prone districts in 17 states including all of the 8 North Eastern States. The implementation of the project commenced in October, 2002 and is expected to be concluded before Dcember, 2007. The Programme components include awareness generation and public education, preparedness, planning and capacity building, developing appropriate policies, institutional, administrative, legal and techno-legal regimes at all administrative levels. Disaster management plans have been prepared for about 3,500 villages, 250 gram panchayats, 60 blocks and 15 districts. Elected representatives of over 8000 Panchayati Raj Institutions have already been trained, besides imparting training to Members of voluntary organizations. Over 20,000 Government functionaries have been trained in disaster mitigation and preparedness at different levels. The thrust of the programmed is to build up capabilities of the community since the community is invariably the first to respond. Large scale awareness generation bringing out specific dos and don’ts is crucial to disaster mitigation. A steering committee for a mass media campaign was created for this purpose. The committee is still in process of developing profiles for inaction. The various prevention and mitigation measures outlined were aimed at building up the capabilities of the community, voluntary organizations and Government functionaries at all levels, but the major task yet unresolved is the vulnerability reduction. The initiatives should be as such that prevention and mitigation is a part of day to day life. There is a need of firm conviction that a disaster like the Orison cyclone, the Buhj earthquake and the Tsunami would not be allowed to reoccur in the country at the cost of the number of human lives, livestock and loss of property and means of livelihood which occurred.

The two aspects of Disaster Management which pose challenges of a more professional equipped and readily responsive approach are: • Pre-Disaster Phase/ Disaster Preparedness: “Forewarned is Forearmed” • Post Disaster: “Managing disaster after disaster” The Construction of early warning systems, getting them to work satisfactorily and sustaining them at appropriate levels of operational efficiency

Disaster Management

and effectiveness are challenges to management. Even when scientific monitoring and predictive capabilities exist, to make warning systems functional efforts need to be sustained. Design requires effective integration of expertise from scientific and technical disciplines (e.g. geography, meteorology, geology), behavioural, sociological and other scientific disciplines. Mapping exposure to people and the proper identification of the need to warn people is inevitable. Components such as, Risk knowledge (Probability of natural events, exposure of people and property, vulnerable communities), Technical Monitoring and Detection ( Remote Sensing, data collection and transmission), Forecasting capabilities (modelling), Warning (Message Design, communication technology, message dissemination) and response (public knowledge) are to kept in consideration for an early warning system. Rapid professional response to disasters is the prime challenge during the disaster phase. The lack of professionally trained rescue teams, specialized dog squads to look for live bodies and the lack of centralized resource inventory for emergency response leads to chaos. Specialist search and rescue units to be requisitioned to the site of an incident should be the priority. Regional response centres should be set up in different parts of the country having well equipped resources for being able to response to any hazard/calamity. Equally important are the well equipped bedded mobile hospitals with all medical and emergency equipment to extend assistance to the hospitals nearby. The air lift facilities should be developed on an independent basis to provide facilities to specialist rescue teams. Use of New and Improved Technology for Monitoring, Assessing, Forecasting and Communication of Information Natural disasters are inevitable and it is almost impossible to fully recoup the damage caused by the disasters, but it is possible to minimize the potential risk by preparing and implementing developmental plans to provide resilience to such disasters and to help in post disaster reduction. Disaster response and recovery efforts require timely interaction and coordination of public services to save lives and property. Access to information is crucial for the effective management of disasters. All those who are concerned with managing disasters necessarily have the need to access timely and accurate information. Normally, a considerable amount of money is spent on just finding the relevant information. This happens because the information is stored redundantly in several places and in several formats. Today, Information Technology (IT) is used in this field for increasing the efficiency and effectiveness in coping with a disaster. The prime concern during a disaster is the availability of the spatial information and the dissemination of this information to all concerned. Maps and spatial information are important components of the overall information in case of any disaster event (floods, earthquakes, cyclones, landslides, wildfire, famine, and so forth). Hence mapping

and spatial information acquisition becomes vital for any Disaster Management effort. GIS has emerged as a very important methodological tool for effective planning, communication, and training in the various stages of the Disaster Management cycle. GIS can fulfill the data requirement for monitoring, assessing and mitigating the needs of Disaster Management. With the increased availability of high resolution data, the opportunities have widened for a more detailed and rapid analysis of natural hazards in a fast, easy and cost-effective manner. The ability of GIS to visualize information, see patterns and relationships that are otherwise apparent, makes it a powerful and methodological tool for management. GIS allows disaster managers to quickly assess and visually display critical information by location. The key advancement in GIS technology is Reprocessing, Revisualization and Geodatabase. The geodatabase view contains the datasets that represent geographic information in generic terms of models as: features, raster, topology, networks, etc. The geovisualization is the set of intelligent mapping which shows the features and its relationship on the earth’s surface. The geoprocessing view is the analytical function which derives a new dataset for conceptual analysis. Internet GIS can be used to plan for, respond to and recover from emergency situations, providing personnel the most accurate information when it’s most needed-constantly. In other words, Internet GIS gives the emergency management professionals the ability to assemble large amounts of public information about their community, and analyze and use the information in an efficient and intelligent manner. The GIS data organization format displays graphic data in a format which is easy to understand. The system’s database may show boundaries, topography, road network, utility and supply lines and other features vital to disaster planning. Linked with an extensive database that provides capabilities for real-time command and control, Internet GIS transforms disaster response into regular emergency management exercise. The pre-disaster preparedness activities like risk identification, risk assessment, awareness and warning are aimed at those actions, which are taken to limit the impact of a natural phenomenon by structuring response, and for establishing a mechanism for ensuring a quick and orderly reaction. This can be organized very efficiently through the use of GIS on the Internet, for example by making available the risk maps, as well as the “dos and don’ts” on the Internet. It can also allow carrying out some basic “what-if” scenario analyses. An Internet GIS based emergency management network can help in ensuring effective public safety.

Increased Community Preparedness and Preventive Measures While disasters strike a wide region of the nation, the impact is always felt at the community level, although it may hit one or several communities at once. Being at the forefront, the communities need to have the capacity to respond to the threats themselves. It is for this reason that communities should be involved in managing the risks that may threaten their wellbeing. To be effective, the community based Disaster Management approach promotes a bottom up approach working in harmony with the top - down approach, to address the challenge and difficulties. Local communities must be supported in analyzing their hazardous conditions, their vulnerabilities and their capacities as they see themselves. The CBDM should forefront opportunities for the local community to evaluate their own situation based on their own experience. Under this approach communities should be proactive in not only the decision making process but also in the implementation process. Transparency of activities and the dissemination of knowledge and information encourage people’s participation in activities.

WWW will lead to an enormous increase in the usage and accessibility of spatial data. In today’s context, the usage of GIS is normally restricted to a community of trained experts. Making GIS applications available through the World Wide Web could make this technology accessible for many more people. For the large group of GIS inexperienced users on the Net, the handling of a Web GIS needs to be much simpler to use than existing stand-alone GIS. With technology becoming more user-friendly and cost-effective in India, the Internet can now be used for the management of disasters in India as well. For example, it can be used effectively in the event of any disaster for providing the first hand information about the extent of damage, the areas affected and to direct the rescue and relief operations. Taking the case of a hypothetical earthquake event, the first information that would be needed, is the location of the epicenter and the extent of the worst affected areas. The Internet GIS, through its applications, would enable the emergency managers to have a map of the affected area along with other statistics such as the number of houses, the population, using which an estimation of the causalities and damage can also be done. The information stored online becomes widely accessible to the concerned agencies and people, and the various control rooms can be established having interconnections through a wide area network. This Internet based GIS, system can also help in accessing, the various map layers such as the transportation network- the network of rails and roads, the communication network and the status of infrastructure- physical as well as social. The information on the various road links, which get cut off due to any catastrophic event, can be updated on the net so that a clear picture of the available links can be provided, and the relief operations can be directed accordingly. Also, the information about the nearest hospital and other emergency services such as fire stations can be provided. The worst affected areas can be marked and all those regions where relief has already been provided can be shown on the maps. This enables the relief agencies to regulate their activities effectively. Apart from the applications during the disaster and post disaster, an Internet based GIS system can serve as a vital media for providing information related to disaster and during the pre-disaster phase, to provide preparedness measures. Overall, the use of Internet GIS has tremendous scope in the Indian context, considering the vulnerability of the country to disasters of various types, the extensive use of spatial data in Disaster Management, and the growing popularity of the Internet. It has great potential, and has been put to good use in the other developed and developing countries as well. At the same time, the use of Internet GIS in the Indian circumstances also poses some challenges, which need to be overcome in the coming years. • The existing dependency of Internet access on normal communication network, which may not work during disasters • Sophisticated analysis and modelling not possible • Higher bandwidth requirement • Mobile internet still not popular in India

Disaster Management Challenges and Opportunities to Disaster Management in India

Challenges and Opportunities to Disaster Management in India CONCLUSION

The following conclusions can be drawn within the framework of this paper: • •

• • • • •

Disaster Management has to be pro-active and multi disciplinary in approach Recognition of the emerging challenges such as the framework of disaster prevention, mitigation and preparedness which should be initiated at Central and State government, levels the community, civil society organization and media involvement are needed in order to achieve the goals together for a safer India. The vulnerability reduction is an important task in the scenario of hybrid natural hazards and multiple man made hazards. Information and communication technologies are indispensable for the preparing, planning and successful implementation of Disaster Management Initiatives. Internet GIS can be very much used for coordinating and managing the spatial data display and analysis needed for the various agencies involved in the various stages of the disaster management cycle. More emphasis has to be given on building human and institutional capabilities to strengthen coordination and linkages. Need for sharing data and information for rapid response.

Disaster Management

Disaster Management The speed and enormity of sudden disasters has forced man to react in a speedy way to come to the rescue of the people involved. Following factors are necessary to accomplish this: The exact location of the disaster site and the type of disaster, as these determine the sort of aid required. This book will provide a broad range of critical and practical ideas and intensive information with the latest data regarding Disaster Management at local, regional, national and international levels. The importance of Warning Systems, Remote Sensing, GPS (Global Positioning System) and GIS (Geographical Information System) cannot be overemphasised as with highly trained people understanding and using these equipment, several thousands of lives will be saved in the future. Jagbir Singh is Senior Lecturer, Department of Geography, Swami Shraddhanand College, University of Delhi, Delhi, India. For the last 12 years, he has been engaged with issues concerning the environment, disasters, hazards and the application of Remote Sensing, GPS and GIS at local, regional, national and international levels. He has authored Tourism Geography; Tsunami Disaster & Its Management; Environment and Development: Challenges & Opportunities, and Society, Sustainability and Environment (ed). Presently, he is engaged in research on Ecology and Environmental Threats to the Great Barrier Reef—Australia.
