Circumpolar Health Atlas This is an atlas about the health of the diverse populations who inhabit the circumpolar regions in the northern hemisphere. It uses maps, charts, tables, and images to describe and explain visually the major health patterns and related issues. It is intended to provide health researchers, service providers, and policy makers working in the North and for the North with a broad and multidisciplinary understanding of northern conditions to put health into its proper context. The atlas is in five Parts. Part One provides a general overview of the physical features of the lands and seas, climate patterns, and the flora and fauna, all of which influence human settlement and development, and thus the people’s health. Part Two focuses on the diverse cultures and languages of the peoples, their origins and genetic relationships, archaeological evidence of their early settlements and migrations, more recent historical and political development, population trends, the towns and villages they inhabit, and the social and economic conditions under which they live. Part Three is about health conditions, with specific focus on the health of children and youth; reproductive health; infectious diseases; chronic diseases such as cancer, cardiovascular diseases, diabetes and obesity; injuries and violence; and mental health. Part Four covers different types of health determinants, their distribution and how they may be causally associated with specific health conditions: genetic susceptibility; the cold and dark environment; living conditions; diet, nutrition and physical activity; and smoking, alcohol and substance use. Part Five describes health systems and their policies, resources, and services. It concludes with education and research, which are potential strategies for improving health.

Foreword
T
he Nuuk Declaration on Arctic Health signed in February 2011 by representatives of the Member States of the Arctic Council emphasizes the need for increased circumpolar sharing of knowledge to address common health challenges and strengthened collaboration in health monitoring. The Circumpolar Health Atlas is a concrete realization of this commitment. It lays the foundation for circumpolar cooperation as it illustrates the similarities and differences among the circumpolar countries and regions. It is a valuable tool for health planners and decision makers across the Arctic and will help us identify best practices and solutions to common problems. It is also a beautifully made book and an enjoyable introduction to the Arctic, its nature and peoples, and not the least its human health issues. I congratulate the editors for their vision and recommend the Atlas to readers all over the Arctic, and indeed the rest of the world.

Preface
T
he seed for this atlas was planted when my long-term colleague Peter Bjerregaard and I were editing the book Health Transitions in Arctic Populations (also published by the University of Toronto Press) as a contribution to the International Polar Year.
We included ten coloured maps in the centre of the book which we considered essential as geographical guide posts in following the text. While many graphs and tables were sprinkled throughout the book, there was not a single photograph used as an illustration. Health Transitions in Arctic Populations was fine as a data-studded academic treatise, but it lacked appeal for the general public. A different kind of book on circumpolar health was needed. The Circumpolar Health Atlas uses maps, charts, tables, and images to describe and explain the many issues of circumpolar health to the general reader. Even health workers who are already familiar with, or have worked in one or more of the northern regions, will find much new information in these pages, as will health workers who have not yet travelled there and those who are in contact with their circumpolar colleagues. For the complete stranger to the North, this book could be an informative guide to the many aspects in the Arctic that have a direct and indirect influence on human health, such as geography, history, economics, archaeology, anthropology, and biology. For individuals already working somewhere in one of the northern regions – including health care professionals, policymakers, administrators, researchers and teachers, whether in government agencies or non-governmental organizations – there is much that will be of interest. In collecting visual materials for this atlas, we tried to achieve a balance among geographical regions and different topics. Personal preferences certainly came into play, and we may not have satisfied all our readers in our ultimate choices. We accessed multiple sources, from NASA to historical archives. Along with many of our friends, relatives, and colleagues, we contributed photographs from our extensive personal collections. We also have bought the rights to some spectacular images from professional photographers. As the many pages of credits and documentation attest, no stone was left unturned in our search to find the “perfect” illustration for a particular idea and issue.
Much of the text is based on the original chapters in Health Transitions in Arctic Populations, rewritten, considerably shortened, and updated. We thank the original contributors for the underlying research. The amount of text has been kept to a minimum, and we have not intended to undertake a comprehensive literature review. There are no citations within the text, a deliberate decision taken to make this atlas appealing to the non-academic reader. However, a list of the works consulted in the preparation of the atlas and the sources for specific data cited are provided. For those who wish to pursue a specific topic in depth, please refer to the comprehensive bibliography in Health Transitions in Arctic Populations. Our team of editors worked hard, admittedly in fits and starts. Rajiv Rawat is the artist among us whose talents are evident in the graphic design and layout of the atlas. Winfried Dallmann drew and redrew most of the maps. Susan Chatwood and Peter Bjerregaard contributed to the conceptualization, writing, and editing of this project. Beth McAuley and her assistant Nina Hoeschele were meticulous in copyediting the text and captions. We are indebted to acquisitions editor Daniel Quinlan at the University of Toronto Press for taking an interest in our proposal and shepherding it through the approval and production process. Production manager Ani Deyirmenjian provided invaluable advice on the technical aspects of the layout and artwork. The production of this atlas benefitted from financial support from the Canadian Institutes of Health Research through the award of the five-year team grant in circumpolar health research (CTP-79853) to Kue Young. In addition to supporting the operation of a series of research projects, its knowledge dissemination component permits works such as this atlas to be researched and produced. For the editors, The Circumpolar Health Atlas has been a labour of love, and we hope that we have created not just a scientific book, but also a work of art! Kue Young Senior Editor

Part One The Circumpolar World Land of the midnight sun – North of the Arctic Circle, the sun never sets below the horizon in the summer for 24 continuous hours at least one day a year. On the Arctic Circle itself, this day falls on the summer solstice [June 21]. Conversely, the sun never rises above the horizon on the winter solstice [Dec 21], and further north, there is continuous darkness for 24 hours at least a day a year. In reality, the midnight sun can be seen south of the Arctic Circle due to atmospheric refraction. The Arctic Circle itself is not fixed, as it moves with changes to the Earth’s axial tilt, and is currently drifting northwards by about 15 metres per year. [Accent Alaska]

1. Introduction Organization The atlas is organized in five Parts: Part One provides a general overview of the geography of the Arctic – the physical features of the lands and seas, climate patterns, and its flora and fauna, all of which influence human settlement and development, and thus the people’s health.
Fig. 1.1 – Aurora borealis in the night sky Named after the Roman goddess of the dawn, the aurora borealis (also called northern lights or polar lights) is visible in many parts of the Northern Hemisphere. It is a diffuse, coloured light caused by ions from the solar wind originating in the Sun colliding with oxygen and nitrogen atoms in the ionosphere (the upper atmosphere, above 100 km). The colours (green, red, or blue) depend on the altitude where collision occurs and the type of atoms involved. [J.Strang/USAF]
T
his is an atlas about the health of the diverse populations who inhabit the circumpolar regions in the northern hemisphere. As an atlas, it uses maps, charts, tables, and images to describe and explain visually the major health patterns and related issues. As the editors, we would like to make it clear to the readers that we define and conceptualize “health” very broadly, and it is also our conviction that health researchers, service providers, and policymakers working in the North and for the North need a broad and multidisciplinary understanding of northern conditions to put health into its proper context.
Part Two focuses on the human dimension – the diverse cultures and languages of the peoples, their origins and genetic relationships, archaeological evidence of their early settlements and migrations, more recent historical and political development, population trends, the towns and villages they inhabit, and the social and economic conditions under which they live. Part Three looks at diseases or health outcomes. After reviewing the overall health status indicators, the focus is specifically directed on the health of children and youth, reproductive health, infectious diseases, chronic diseases such as cancer, cardiovascular diseases, diabetes and obesity, injuries and violence, and mental health. Part Four covers different types of health determinants, their distribution, and how they may be causally associated with specific diseases and health conditions. Included in the discussion are genetic susceptibility, the cold and dark environment, living conditions, diet, nutrition and physical activity, and smoking, alcohol and substance use.
Fig. 1.2 – Finding north in the night sky From the Great and Little Dipper one can locate Polaris, the North Star, with the naked eye. The Hubble Telescope reveals that Polaris is a triple star system, composed of Polaris A, Ab, and B. [NASA]
Part Five describes health systems – what policies are in place, how many resources are available, and how services are organized and delivered. It concludes with education and research, both as a component of the health system, and also as potential strategies for improving health.
Defining Circumpolar In this atlas, we use the terms circumpolar and Arctic interchangeably. Table 1.1 provides a glossary of various “northern” terms. We are interested in the vast geographical region which stretches across the “top” of the world. Its precise borders, however, are difficult to define. The Arctic Circle, at 66º34’N, is an imaginary line on the map, serving as a marker of solar radiation, encircling the “land of the midnight sun” (Figs. 1.1, 1.2). Geographers have used a
3 Table 1.1 – A glossary of “northern” terms Arctic
From the Greek arktos, for bear, referring to the constellation Ursa Major. The North Star or Polaris, in Ursa Minor, is directly above the North Pole.
Polar
It means “of the pole,” but which pole? The Geographic Poles are at the ends of the Earth’s axis of rotation, joined by an imaginary line that runs through the planet’s centre. The True North is at 90oN, where all longitudes converge. O
The Magnetic Poles or dip poles are where the Earth’s magnetic field points vertically downward, or 90º dip. The ends of a compass needle point to the magnetic poles. Their locations are constantly changing due to the magnetic changes in the Earth’s core. When first located by James Ross in 1831, the North Magnetic Pole was on Boothia Peninsula; in 2005 it was at 82.7ºN, 114.4ºW, west of the Sverdrup Islands. The Geomagnetic Poles: Think of the Earth as a giant magnet with two poles, where the magnetic field intersects the Earth’s surface. The North Geomagnetic Pole is now off the northwest coast of Greenland, at 79.7ºN 71.8ºW. Boreal
From the Greek boréas, the north wind. It is used in terms such as “boreal forest” and “aurora borealis” (northern lights)
Nordic
This is just another way to say “northern” but it is generally used in referring to the “Nordic” countries or Scandinavia or the people living there.
variety of markers to delimit the extent of the arctic region, including the treeline, the 10ºC July isotherm, and the line of continuous permafrost. These do not serve a purpose in our atlas. As most health statistics are collected by government agencies, they are usually aggregated by administrative divisions. For an atlas about health, it is therefore convenient to define our boundaries based on such divisions (Table 1.2, Fig. 1.3, 1.5).
WESTERN HEMISPHERE The whole of Alaska, Greenland, Iceland, and the Faroe Islands are included. Northern Canada in this atlas is defined as the three northern territories of Yukon, Northwest Territories, and Nunavut. It should be noted that the Inuit homelands of Nunavik in northern Québec and Nunatsiavut in Labrador are often included as part of the Canadian Arctic.
SCANDINAVIA As a geographic term, “Scandinavia” has different meanings and usages. In its broadest sense, it encompasses all the Nordic countries and their dependent territories. More narrowly, it refers to only Denmark, Norway, and Sweden. The term “Fennoscandia” is often used to refer to the contiguous countries of Norway, Sweden, and Finland. The northernmost “counties” in Norway (fylke), Sweden (län), and Finland (lääni) constitute the northern regions of those countries. In 2010, Finland abolished the lääni and replaced it with the regional state administrative agency (aluehallintovirasto or AVI). There was little change to the boundaries in the northern regions of Oulu (now called Pohjois-Suomi) and Lappi.

RUSSIA The Russian North (Rossiyskiy Sever) stretches across the Eurasian landmass. “Siberia” (Sibir) tends to be used by people outside Russia to refer to all of Russia east of the Ural Mountains. Within Russia, Siberia has a more restricted meaning geographically, one which excludes the Far East. The Russian Federation is composed of different types of administrative divisions called federal “subjects” (subekty), including republic, kray, oblast, autonomous okrug, and federal city, each with varying degrees of autonomy.

[W. Dallmann]
4 Table 1.2 – Circumpolar countries and regions We anglicize and simplify the names of Russian regions by dropping their adjectival endings (e.g., Magadan Oblast from Magadanskaya oblast). Russian Evenkiyskiy and Chukotskiy refer to Evenkia and Chukotka places and not to the Evenk and Chukchi people. We use Evenkia and Chukotka for these AOs instead of the more correct Evenkian and Chukotkan AO. Chukot AO is sometimes used but is incorrect as there is no such place or people called “Chukot”. For AOs named after the dominant indigenous people in the region such as Nenets, Koryak, and Khanty-Mansi, these names will be used. Yamalo-Nenets refer to Yamal the place and Nenets the people. Note that Nenets is not the plural form and there is no such word as Nenet.

Arctic Eurasia
Arctic North America Fig. 1.7 – The Arctic at night This image of the Earth at night shows the most urbanized areas. Much of the Arctic tundra and taiga remain “in the dark”, with the exception of northern Fennoscandia where bright city lights extend northwards past the Arctic Circle. The Prudhoe Bay oil field in the North Slope of Alaska is brightly lit. A thin line along the southern fringe of Siberia marks the Trans-Siberian Railway. [NASA] Fig. 1.6 – The Arctic seen from space This Arctic mosaic is composed from several passes of the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite on June 28, 2010. [NASA]
Arctic from Space There is no better way to appreciate the expanse and majesty of the Arctic than to look at it from space (Fig.1.6). The remoteness and sparse distribution of population centres is starkly evident in satellite images of the world at night (Fig.1.7). Satellite images are used extensively in this atlas as they provide a truly circumpolar perspective.
An autonomous okrug (AO), with the exception of Chukotka, is generally a part of some higher level unit such as an oblast or a kray, and usually represents the traditional territory of some indigenous ethnic group. Statistical data are usually available for these AO separately. As of 1 January 2007, Taymyr, Evenkia, and Koryak AOs ceased to exist as distinct federal subjects, and were fully absorbed into the Krasnoyarsk kray and the Kamchatka kray, although some statistics continue to be produced for these former AOs. The flags or coats of arms of the circumpolar regional governments are shown in Fig. 1.4.
Although it is a country, Iceland is considered a region when compared with the other subnational regions. Greenland and, to a lesser extent, the Faroe Islands, are not quite fully independent countries, and they are listed as “regions.” It is customary to compare them with Denmark, although in statistical terms, their data are rarely included with Denmark’s. In all, the Arctic regions included in this atlas encompass 17 million square kilometres, sustaining a sparsely distributed population that had reached just under 10 million by the end of the first decade of the twenty-first century.

2. Lands and Seas
T
he physical features of the Arctic lands are varied. There are plains, plateaus, mountains, hills and valleys, traversed by rivers and dotted with lakes. Its long coast line is indented by fjords and the majestic glaciers plunge dramatically into the sea (Fig. 2.1). As the map of physical regions (Fig. 2.2) shows, there is remarkable symmetry between Eurasia and North America at their northernmost margins.

The 90-km wide strait separates Asia (Chukotka Peninsula) and North America (Seward Peninsula). St Lawrence Island is visible to the south.
Diversity of landscapes
[NASA]
Starting with Alaska and moving from west to east across the circumpolar world, we first encounter the windswept, treeless islands out on the Bering Sea. The Big and Little Diomedes are separated by the International Dateline and also the United States–Russia border (Fig. 2.3). The Aleutian Islands is a chain of over 300 small volcanic mountains, jutting into the Bering Sea from the Alaska Peninsula (Fig. 2.4). The westernmost group, the Commander Islands, is within Russian territory. Alaska spans some 20º of latitude (52º– 72ºN) and offers a diversity of landscapes, from the mountainous archipelago with deep, narrow fjord-like inlets of the “panhandle” (Fig. 2.5), to the thirty-five mountain ranges (notably the Chugach and Kenai Mountains, Brooks Range, and Alaska Range), glacial lakes and hills of the interior, to the flat tundra of the north and northwest. Alaska and much of the Yukon are within

the North American Cordillera, a complex of mountains, plateaus, and valleys that make up the northward extension of the Rockies. Here can be found Mount McKinley (Fig. 2.6), which, at 6,200 metres, is North America’s highest peak. Canada’s highest peak, Mount Logan at 6,000 metres, is across the border in the Yukon.
the east it slopes gradually into the low-lying mountains of Finnmark and Lapland and the lowlands of Sweden.
The Interior Plains extend northward through the Mackenzie River valley and across the Great Plains of the continent. The Arctic Archipelago (Fig. 2.7) contains coastal plains, plateaus, and mountains (Fig. 2.8). The Canadian Shield consists of ancient Precambrian rocks, which have been smoothed and moulded by glacial erosions (Fig. 2.9), and covers much of Nunavut, the eastern Northwest Territories, and Greenland. The Scandinavian Mountains or the Fells are often referred to as the “keel” of Fennoscandia (Fig. 2.10). The keel forms the border between Norway and Sweden. To the west, it plunges precipitously into the fjords along the coast of the Norwegian Sea (Fig. 2.11). To
The European North of Russia extends from the Kola Peninsula and Kareliya in the west, across the Vychegda Lowland and Pechora Basin to the Urals in the east, with its northern shores washed by the White, Barents, and Kara Seas. Much of the land is low lying and swampy, with tundra in the north and taiga in the south. The swampy flat plain of West Siberia extends from the Ural Mountains to the Yenisey River. Beyond, the Central Siberian Plateau descends to the north into the Northern Siberian Lowlands. Northeast Siberia is a huge system of mountain ranges (such as the Verkhoyansk and Cherskiy) and highlands (such as the Kolyma and Chukotka). To the north, between the mountains and the Arctic Ocean, lies the Yana-Indigirka and the Kolyma Lowlands.

Rivers and lakes Several major rivers course through northern Canada, such as the Mackenzie and Coppermine Rivers that drain into the Arctic Ocean. The Yukon and Kuskokwim Rivers empty into the Pacific Ocean off Alaska and form one of the largest deltas in the world, one which is mainly tundra (Fig. 2.12).
(b) Healey Canyon and the Nenana River, which is a tributary of the Tanana River and drains into the Yukon River in the Alaskan interior. [K. Young]
The western Canadian Arctic is dotted by wetlands and several large lakes, notably Great Bear and Great Slave, which are part of the chain of lakes that extends southeastward to the Great Lakes. In Arctic Russia, several major rivers drain into the Arctic Ocean – the Northern Dvina, Mezen, Pinega, and Pechora Rivers in European Russia, and the Ob, Yenisey, Lena, Indigirka,
and Kolyma Rivers in Siberia (Fig. 2.13). Important travel routes throughout history, they continue today to be important transportation arteries that traverse huge northern expanses.
Volcanoes and Earthquakes Some of Earth’s more seismically active places are located within Arctic regions (Fig. 2.14). The collision of the earth crust’s tectonic plates created the Pacific Ring of Fire, where the great majority of the Earth’s earthquakes and volcanic eruptions occur. In the north, it encom-

erupted for the first time since 1821. The dense clouds of volcanic ash that were released into the atmosphere brought air traffic across much of Europe to a standstill (Fig. 2.15).
The Mid-Atlantic Ridge runs right across Iceland, where the Eurasian plate and North American plate have been drifting apart. Iceland also sits on top of a volcanic hotspot, accounting for the large number of active volcanoes in the country, the most volatile of which is Hekla. In March 2010, the Eyjafjall volcano
Mention “Arctic” and most people think of ice. Those portions of our Earth consisting of frozen water constitute the cryosphere. It includes ice on land – snow cover, glaciers, ice sheets, ice caps, frozen lakes and rivers, and permafrost underground – and ice on the seas – sea ice and icebergs (Fig. 2.16 – Fig. 2.20).
An Icy World
The Arctic cryosphere has witnessed dramatic changes in recent decades, with the retreating and thinning of sea ice, melting of glaciers and the Greenland ice sheet, thawing of the permafrost, and depleting snow cover. Such changes seriously affect solar radiation, ocean circulation, and sea level, the habitats of marine and terrestrial animals, coastal erosion, and the intensity of river flow. They also affect human activities such as navigation, power generation, and community infrastructure. These changes can range from the local to the global.

Fig. 2.16 – The Greenland ice sheet Over 80 per cent of Greenland’s area is covered by the ice sheet, which is as thick as 3,500 metres in some places. It is one of two remaining ice sheets from the Pleistocene Ice Age (the other is in Antarctica). An ice sheet extends greater than 50,000 square kilometres whereas the area of an ice cap is smaller.

Fig. 2.19 – Icebergs Icebergs originate from glaciers or ice caps and are composed of frozen fresh water. Sea ice is frozen sea water. Icebergs come in different sizes – from “growlers” that are higher than 1 metre and longer than 5 metres to the very large ones that exceed 75 metres in height and 200 metres in length. They also come in many shapes – tubular, dome, pinnacle, wedge, and so on. Typically, only a small portion of the iceberg appears above water, with as much as 85% of it being submerged.
(c) Icebergs float past Disko Bay, Greenland. West Greenland is the source of the majority of icebergs in the North Atlantic. [P. Bjerregaard]
15 Fig. 2.20 – Sea ice Sea ice may be annual, which forms in the winter and melts in the following summer, or multiyear, which remains frozen year after year, even during the summer.
(a) Spring in the western Canadian Arctic: Sea ice in the Beaufort Sea has started to break up. Open water separates the land from the dense pack of sea ice. Ice still fringes much of the land, but it is thinning. The Mackenzie River flows ice-free to a broad partially frozen delta. One large forest fire can be seen in the southwest. [NASA]
(b) Various types of sea ice congregate along the east coast of Greenland in late March. Clinging to the shore is landfast sea ice, impervious to ocean currents. Further away from land are large round pieces of multiyear sea ice that were carried to this location by the East Greenland Current. Ocean currents can smooth ice fragments into round shapes. Even farther out to sea are much smaller fragments of ice being swirled by the small surface currents. [NASA]

3. Changing Climate
C
limate is a statistical concept that summarizes a variety of weather data such as temperature, humidity, precipitation, atmospheric pressure, and wind over long periods of time. The World Meteorological Organization uses a thirty-year period (e.g., 1961–1990) to define “climate normals” for a specific locality. Climate is relevant to health because it constitutes part of the physical environment to which all human beings are exposed.
Fig. 3.1 – The climate of circumpolar regions
Köppen-Geiger climate classification ET EF Dwd Dwc Dwb
This is extracted from the World Map of Köppen-Geiger Climate Classification. The main climates are: A – equatorial or tropical; B – arid; C – temperate; D – cold or snow or continental; E – polar, of which C, D, and E are present in circumpolar regions. Within each type are subtypes based on precipitation: s (dry summer), w (dry winter), f (fully humid); and on temperature: a (hot summer); b (warm summer); c (cold summer); d (very cold winter). There are two subtypes of polar climate T (tundra) and F (frost) based on maximum temperatures. [W. Dallmann, based on Kottek et al. (2006)]
Climatic variation exists due to mountain barriers, proximity to open waters, extent of surface snow and ice cover, and the duration of daylight and darkness. Despite the image of the Arctic as a white expanse, precipitation is generally low, and the high Arctic is in fact a polar desert. Fig. 3.2 lists the mean January and July temperatures of the circumpolar regions, adjusted for the size of the population experiencing that climate.

Current Patterns The type of climate experienced in circumpolar regions, as defined in this atlas, goes beyond what is usually considered as Arctic or polar and includes continental and even temperate climate. A popular climate classification system, known as the Köppen-Geiger system, is based on temperature and precipitation and correlates with the distribution of native vegetation (Fig. 3.1).

Winter temperatures decrease as one moves eastwards across Siberia and reach their lowest in the northeast, where temperatures as low as –70ºC have been recorded (Fig. 3.3). Ocean currents have a major influence on regional climate patterns because they shift the delivery of heat and moisture (Fig. 3.4). Thanks to the Gulf Stream that sweeps up along the Norwegian coast, the climate in northern Scandinavia is generally warmer than it is other places and regions located at the same latitude. Across the Atlantic, the Irminger Current is responsible for keeping the water open all year round along the west coast of Greenland and as far north as 67º.

Ice Ages
Based on the concentration of air trapped in ice cores from Antarctica, deuterium (D, black) serves as a proxy measure of local temperatures, which correlate with the greenhouse gases carbon dioxide (CO2, red), methane (CH4, blue), and nitrous oxide (NO2, green). Shaded areas represent interglacial warm periods. Data on benthic 18O (grey) from marine records are included to show global ice volume fluctuation. [IPCC-4]
During the Earth’s long geological history, its climate underwent many periods of cold and warm. “Ice Age” is a popular term referring to the period when the Earth was cold and was marked by the presence of large continental ice sheets. Within each ice age there were cooler periods (glacials) alternating with warmer periods (interglacials), and differences in global mean temperatures were as large as 4oC to 7oC. From the human perspective, it is the most “recent” ice age that is of interest. It took place during the Pleistocene Epoch of the geological time scale, which began 1.8 million years BP (Before Present, which is set at 1950). It was during the Pleistocene that the permanent ice sheets of Greenland and Antarctica were established. The Pleistocene was followed by the Holocene, which started around 12,000 years BP. Global temperature fluctuations during the last

600,000 years, deduced from analyses of gases trapped in the ice cores of Antarctica, is shown in Fig. 3.5. Fig. 3.6 schematically expands the time since the Late Pleistocene 130,000 years BP. During the Wisconsinan (in North America) or Weichselian (in Eurasia) glaciation, the earth experienced the Last Glacial Maximum
(LGM), which lasted from about 24,000 to 21,000 years BP. During this period, the continental ice sheets were at their maximum, covering almost half of Europe and all of Canada. Subsequent to the LGM, there were minor excursions of the ice sheets that were called stadials (when they advanced) and interstadials (when they retreated).

Temperature trends were reconstructed based on analyses of “paleoclimate archives” in glacier ice, tree rings, and lake sediments. Four of the five warmest decades during the 2,000-year period occurred between 1950 and 2000. [Reproduced from Kaufman et al. (2009)]
Global climate is largely a matter of balancing radiation among (a) incoming solar radiation, which is affected by changes to the planet’s orbits; (b) the proportion that is absorbed and reflected back, affected by cloud cover, aerosols, or land cover; and (c) the long-wave energy radiated back to space, which can be altered by changes in greenhouse gas concentrations.
Warming Trends The epoch we are now in, the Holocene, is an interglacial one. It is marked by a relatively warmer period called the Medieval Warm Period (from AD 1000 to 1450), followed by the Little Ice Age that lasted till about 1850. These historical climate changes played a significant role in the migrations and settlement of the Arctic by the Inuit and the Norse. However, it is evident that since the 1950s, there has been
a steep warming trend, which is likely the result of human activities (Fig. 3.7). While climate change has been a constant part of the Earth’s history, what is of concern is that the recent rate of change has been much more rapid. The warming Arctic has local, regional, and global significance. Over the next 100 years, the Earth’s average temperature is projected to increase significantly, glaciers and inland ice will melt, the extent of the permafrost will decrease, the extent of sea ice will be reduced (Fig. 3.8), the levels of the oceans will rise, and the weather will be more extreme. In terms of how this will affect human life and well-being in the North, it is possible that we will see an increase in the risk of emerging infectious diseases, the introduction of insect vectors and animal reservoirs novel to the Arctic.

Fig. 3.8 – Reduction in Arctic sea ice a) Sea ice reaches its maximum in March and melts in the summer, reaching its minimum in September. Extent is the total area in which ice concentration is at least 15 per cent. Since 1978, NASA satellites have monitored sea ice growth and retreat, and they have detected an overall decline in Arctic sea ice since 1999–2000, compared to the “baseline” period of 1979–2000. It reached its lowest extent during the summer of 2007. Cycles of natural variability and greenhouse gas emissions (and the resulting rise in global temperatures) likely contributed to the greater reduction of Arctic sea ice. Some models forecast an ice-free Arctic for at least part of the year before the end of the twenty-first century. [Based on data from NASA]
tion, low-lying areas may be flooded, and the melting permafrost could destroy parts of the infrastructure, such as homes, service facilities, and transportation networks (Fig. 3.9). The retreat of shore bound sea ice could make hunting dangerous if not impossible, species survival may be threatened, and thinner ice may result in increased drowning. Worldwide climate warming has the potential to increase transport of contaminants into, and in some cases, out of the Arctic. Local knowledge provides poor guidance due to the rapidly changing conditions.

he circumpolar regions vary in biodiversity. From the temperate rainforest in southeastern Alaska, it decreases progressively northwards through the boreal forest (taiga) to the tundra. While the number of species is small compared to more southerly biomes, individual species may be present in large numbers, and there are seasonal bursts of high productivity. Within one locality, there is also considerable year-toyear fluctuation. Table 4.1 provides a taxonomic guide to selected mammals and birds for the amateur Arctic naturalist.
Mammals The major Arctic mammals include different species of seals and whales, polar bears, muskoxen, caribou/reindeer, walruses, Arctic foxes, hares, and wolves (Figs. 4.1–4.3). Domesticated reindeer are widely distributed and have been husbanded by indigenous peoples in northern Eurasia for centuries. Whales are unequivocally marine mammals who have adapted to a life immersed in the water, as are seals and walruses whose evolution included the development of flippers for swimming and who also spend much time (that includes breeding) on ice floes. It is arguable whether polar bears are marine mammals, as they venture far inland even though they spend much of their lives on sea ice. Marine mammals have an advantage over their terrestrial counterparts in that sea water, which never gets below -2ºC, is balmy compared to the cold air temperature on land, but they do face the problem of needing air to breathe. Leads (long cracks leading to open water) and polynyas (large bodies of open water) are thus critical to their survival in the winter pack ice. Polynyas, especially those that are open all winter
Fig. 4.1 – Terrestrial mammals (a) Polar Bear (Ursus maritimus): The species has a truly circumpolar distribution and can range as far south as the “bottom” of Hudson Bay. Long a symbol or icon of the Arctic, its endangered status is hotly contested between Inuit hunters and wildlife scientists. [S. Chatwood]

(c) Caribou migrations: Herds numbering in the thousands can cover several thousand kilometres. Shown here is the George River herd in northern Labrador. [E. Loring] (d) Caribou or Reindeer (Rangifer tarandus): This member of the deer family is called caribou in North America and reindeer in Eurasia. Circumpolar in distribution, there are many subspecies, such as the barren ground caribou (R. tarandus groelandicus) in the Canadian tundra and western Greenland, and the distinctively shortlegged Svalbard reindeer (R. tarandus platyrhynchus). [V. Dorward]
Fig. 4.1 – Terrestrial mammals (continued) (b) Brown Bear (Ursus arctos): Widely distributed across northern Eurasia and North America, the many subspecies of the brown bear include the much feared grizzly bear (Ursus arctos horribilis) in Alaska and northern Canada and the salmon-fed Kodiak bear (Ursus arctos middendorffi) in coastal Alaska. Brown bears are not to be confused with the black bear (Ursus americanus). Fur colour is a poor guide to species identification despite their common names being based on colours. [V. Dorward]
and in the same place year after year, are rich feeding grounds for whales, polar bears, walruses, and seals. The North Water polynya in Baffin Bay has been known to whalers since the seventeenth century. In the taiga, mammals range in size from
moose, deer, brown and black bears, woodland caribou/reindeer, to the smaller furbearers such as lynxes, wolves, wolverines, foxes, hares, muskrats, beavers, and minks. Some species such as sable are found only in Eurasia and not North America.
25
(e) Moose (Alces alces): In Europe the moose is called elk. Confusingly, in North America there is also an animal called “elk” (Cervus canadensis), which is also called “wapiti.” The antlers characteristic of male moose are termed “palmate.” A dweller in the boreal forest, the moose is among the largest terrestrial mammals in North America and Europe. [K. Young]
(f) Muskox (Ovibos machatus): A contemporary of the woolly mammoth during the Pleistocene, the muskox is found today in northern Greenland, the Arctic Islands, and parts of mainland Nunavut. Its rich and soft wool (called qiviut) is highly prized. In the face of predators such as wolves, a herd would form a defensive circle. [V. Dorward]
(h) Dall Sheep (Ovis dalli) : Famous for their display of surefootedness on steep mountain slopes and ridges, the Dall sheep are found in parts of Alaska and the Yukon. Both sexes have horns, but the males are thick and curved into almost a full circle pointing forward. The brownish coloured and similarly horned snow sheep (Ovis nivicola) are found in eastern Siberia. [V. Dorward]
Fig. 4.2 – Marine mammals: Cetaceans (a) Humpback Whale (Megaptera novaeangliae): These baleen whales have huge plates of keratinous baleen hanging from the roof of the mouth like a comb, which filter out plankton and fish. They are migratory and breed in winter in tropical waters – seen here frolicking in Nuuk Fjord, Greenland. [P. Bjerregaard]
(g) Arctic Hare (Lepus arcticus): In the southern part of its range in Greenland and Arctic Canada, the Arctic hare is white only in the winter. Further north it can be white year round. Other hares with white winter coats can be found elsewhere in the Arctic – the Alaskan hare (Lepus othus) in Alaska and the mountain hare in Eurasia (Lepus timidus). [W. Dallmann]
(b) Humpback whales “bubble net” feeding off the coast of Juneau, Alaska: This is a group effort that involves swimming in a shrinking circle around a school of fish while blowing bubbles, then surfacing with mouth agape. [V. Dorward]

Belugas and narwhals (Monodon monoceros) are toothed whales and permanent residents of the Arctic Ocean. [K. Young] (d) Orca (Orcinus orca): Also known as killer whale, the orca is a member of the dolphin family, which belongs to the toothed whales with the beluga and narwhal. The orca has a worldwide distribution, It preys on fish, seals, other whales, and, even occasionally, birds. [V. Dorward]
Fig. 4.3 – Marine mammals: Pinnipeds The pinnipeds include the true seals (or earless seals), walruses, and eared seals (including sea lions and fur seals). Pinnipeds and whales evolved from terrestrial ancestors which adapted to marine life.
(a) Steller’s Sea Lion (Eumetopias jubatus): Also called the northern sea lion, the Steller’s sea lion is an eared seal found living in the waters of the Bering Sea along the coast of Kamchatka through the Aleutian Islands to Alaska. In recent decades there has been a drastic population decline and the species is heading towards extinction; the cause for this is uncertain. [V. Dorward]
(b) Bearded Seal (Erignathus barbatus): (left) [W. Dallmann] (c) Walrus (Odobenus rosmarus): (above) [S. Kazlowski/ArcticNet]

(b) Horned Puffin (Fratercula corniculata): The horned puffin breeds in colonies on rocky islands off the coast of Siberia and Alaska and feeds by diving for fish. [V. Dorward] Fig. 4.4 – Birds (a) Bald Eagle (Haliaeetus leucocephalus): The bald eagle is the national bird of the United States and its numbers are abundant in Alaska, but in the Lower 48 it once faced extinction. In 2007, it was removed from the List of Endangered and Threatened Wildlife because its numbers had recovered from hunting and the thinning effect of DDT on its eggshells. [V. Dorward]
(d) Snowy Owl (Bubo scandiacus): The snowy owl nests on the ground and feeds on small rodents. The young lose their black feathers as they age. [T.Gosselin/ArcticNet]
Birds About 100 species of birds breed in the Arctic (Fig. 4.4), but only a few live there year round (e.g., gyrfalcon, raven, snowy owl, and certain species of gull, ptarmigan, murre, and guillemot). Most others are temporary residents, staying there only during their breeding season. T h e flocks of migrating geese and ducks herald the changing seasons each year. While food abounds in the short summer, it is dormant or unavailable in the winter. Polynyas are therefore important for seabirds. Migratory birds are dependent on an adequate food supply both at their stopovers and on arrival in the Arctic. Timing is critical because chicks need to hatch when food is most abundant and to grow strong enough for the flight south before food supplies dwindle.
(c) Common Murre (Uria aalge): Also called the common guillemot, this member of the auk family is widely distributed along the northern Pacific and Atlantic coasts. They breed in dense colonies but make no nests. [T. Ikäheimo]
(e) Whooper Swan (Cygnus Cygnus): The national bird of Finland, the whooper swan is widely distributed in Eurasia where wetlands in the taiga provide its breeding habitat. [A. Trepte/Wiki]
(f) Gyrfalcon (Falcon rusticolus) [O. Larsen/Wiki]
(g) Rock Ptarmigan (Lagopus muta) [J. Haugseth/Wiki]
28
(b) Arctic Char (Salvelinus alpinus): A member of the salmon family, the Arctic char spends part of its life in the sea and part in freshwater, although some populations live entirely in freshwater. It has the northernmost range of any freshwater fish. Unlike the Pacific salmon, it spawns repeatedly over several years. Here they are stored in a community freezer in Tuktoyatuk, Northwest Territories. Arctic char is closely related to lake trout (S. namaycush), which live exclusively in freshwater. [S. McDonald]
Fig. 4.5 – Fish (a) Sockeye Salmon (Oncorhynchus nerka): Sockeye salmon is also called red salmon. Like all salmon, it is born in freshwater, spends much of its life in the sea, but returns to the same stream to spawn. Pacific salmon spawns only once, and then dies shortly afterwards. Other species include chum [O. keta], coho [O. kisutch], pink [O. gorbuscha], and Chinook, also called king [O. tshawytscha]. Some salmon travel far and wide in the North Pacific and the Arctic Ocean to the Lena River in Siberia and the Mackenzie River and Bathurst Inlet in Canada. [K. Young]
Fish Fish such as lake trout, whitefish, and Arctic grayling can be found in rivers and lakes, and species such as Arctic char move seasonally from the sea into freshwater areas. These are all members of the salmon family. Other freshwater fish include burbot, sturgeon, and northern pike. Marine species include salmon, cod, halibut, capelin, and herring found off the coasts of Alaska, Greenland, and Eurasia (Fig. 4.5).

Fig. 4.7 – Phytoplankton bloom off Iceland The annual North Atlantic phytoplankton bloom consists of millions of microscopic plantlike organisms called phytoplankton that move from the south to the north, peaking in late spring. Phytoplankton is an important part of the food web. It is consumed by zooplankton, which is the staple of marine mammals such as whales. [NASA]
The Food Web Other “lower” forms of life from unicellular organisms to invertebrates (Fig. 4.6 and Fig. 4.7) are important because they form important links in the food web. Food chains are schematic representations of the prey–predator relationships among species, with humans invariably occupying the top spot. A series of related chains constitute a web. Different webs exist for different types of ecosystems; for example, the terrestrial, lacustrine, and marine web (Fig. 4.8). Food webs are important to human health because of
Atlantic cod

their role in the dissemination and bioaccumulation of environmental contaminants. Lower species such as shrimp and crab are also important economically, and they are harvested in regions such as Greenland. Insects may well be the bane of human residents and travellers in the Arctic, but they are essential parts of the ecosystem, serving a role as pollinators and providing food for birds. They have developed unique adaptations to the cold temperatures, strong winds, and short summer seasons.

Vegetation The treeline demarcating the treeless tundra from the boreal forest, or taiga, is not so much a line as a transitional zone. As one travels poleward, trees become progressively smaller and smaller, and are more widely scattered, until there are none (Fig. 4.9). The soil is dry, thin, and poor in much of the Arctic, and permafrost – perennially frozen ground – can be found widely at varying depths, preventing adequate drainage. Except in the high Arctic Islands where there is only bare rock and gravel, some vegetation, mostly lichens, moss, grass and sedges, and small vascular plants covers large areas, much of it under snow cover during most of the year (Fig. 4.10). In the short summer growing season under continuous daylight, blooming flowers enrich the
Fig. 4.10 – Mosses and lichens on a rocky outcrop
Fig. 4.9 – Vegetation and land cover [UNEP/GRIDA]
Both moss and lichen lack roots and can thrive in areas with little soil cover (such as bare rock) in extreme environments such as the Arctic. Mosses are primitive green plants capable of photosynthesis. Lichens consist of a fungus and a green alga or cyanobactrium that live together in symbiosis. [V. Dorward]
31 landscape with a variety of colours (Fig. 4.11). Even in the High Arctic desert, there are oases where local topography favours plant growth. In the valley of Lake Hazen in northern Ellesmere Island, at 82ºN, over 110 species of flowering plants have been identified. Plant life is an important food source for the herbivores that form a critical link in the Arctic’s food web. The floral emblems of various circumpolar regions are shown in Fig. 4.12. (b) Labrador Tea (Ledum groenlandicum): Labrador tea’s strongly aromatic evergreen leaves are used in beverages and as medicines by the indigenous people of the Arctic. [V. Dorward]
(d) Arctic Poppy (Papaver radicatum): Several species of the Arctic poppy grow in the circumpolar region: the Iceland poppy, Lapland poppy, and Svalbard poppy. Although the flowers are typically yellow, white flowers are also common, especially in cloudy and foggy areas. [K. Hansen/Wiki]
(c) Wild Sweet Pea (Hedysarum mackenzii): Sweetly scented, the roots of the wild sweet pea are poisonous. It is closely related to bear root (H. alpinum), which has edible roots and is a favourite of grizzly bears. [V. Dorward]
(e) Arctic Cotton Grass (Eriophorum spp): Arctic cotton grass is a sedge rather than a grass. Several species grow in the Arctic, including those with a single “head” of cotton at the top of each stalk such as the E. vaginatum and the many-headed E. angustifolium. [S. McDonald]
(f) Kamchatcha Lily (Fritillaria camschatcensis): Grown in eastern Siberia, Kamchatka, and Alaska, it is also called chocolate lily for the colour of its flowers and not its foul smell. [T. Ikäheimo]

The boreal forest is dominated by coniferous trees (such as spruce, pines, fir, and larch), and also hardwoods such as birch, alder, willow, and aspen (Fig. 4.13). Most but not all confers are also evergreen, that is, they do not shed their leaves in winter. Larch (also called tamarack) is the exception, with its needles turning golden in the late summer and falling off in the autumn. Local drainage and soil texture determine the predominant tree species. Some genera have several distinct species, each occupying different regions of the taiga. With warming climate, there is a gradual

northward movement of the treeline and the appearance in the north of species more typical of southern climes. As the whole of Alaska is defined as a circumpolar region, the temperate rainforest in southeastern Alaska offers yet another type of ground vegetation. This rainforest consists primarily of coniferous trees (especially Sitka spruce and western hemlock within Alaska), and extends along the coast southwards into British Columbia and the Pacific Northwest states.

5. Cultures and Languages
T
he population of circumpolar regions belongs to many different ethnic and cultural groups (Fig. 5.1). Many groups consider themselves to be indigenous, while others came as settlers and colonizers from other lands. Today, the ethnic diversity of the circumpolar regions is further enhanced by increasing immigration from all over the world to the Arctic states, including their most northern regions (Fig. 5.2).

Language Families The world’s languages can be grouped into families, although linguists and anthropologists do not completely agree on their classification and nomenclature. Table 5.1 presents one approach. In Arctic North America, the Eskimo-Aleut family extends from Greenland to Alaska and across the Bering Strait to Chukotka. The Na-Dene family comprises the Athapaskan languages spoken in Alaska and northern Canada (Fig. 5.3), as well as Haida and Tlingit. In the easternmost area of Asiatic Russia is the Chukotko-Kamchatkan family, with two branches: one comprises Chuckchi and Koryak, and the other comprises Itelmen, which is spoken in Kamchatka. The Altaic family covers much of the Far East and Central Asia, and is divided into three branches: a Turkic branch, which is a large conglomerate of some thirty languages across the steppes, from Turkey to the Arctic, including Yakut and Dolgan; a Mongolian branch, which includes Buryat; and a Tungusic branch, to which the Even and Evenk belong. Situated astride the Ural Mountains dividing Europe from Asia is the Uralic family. It can be further divided into Samoyed (which includes Nenets, Enets, Nganasan, and Selkups); Finnic, to which Finnish, Sami (Fig. 5.4), Komi, and Udmurt (as well as Estonian) belong; and Ugric, which includes Khanty and Mansi (and also Hungarian). The Russian and Scandinavian languages are all members of the vast Indo-European family of languages, which include English and French, two of the colonizing languages of Arctic North

Indigenous Peoples There are many indigenous peoples in the circumpolar regions, including some groups such as the Sami, Inuit, Dene, Aleut, and Evenk whose territories extend across two or more nation states. There is not one universally accepted definition of indigenous peoples, not even in the United Nations Declaration on the Rights of Indigenous Peoples. Characteristics of indigenous peoples include the following:
» they usually live within (or maintain attachments to) geographically distinct ancestral territories; these territories were occupied before the embracing nation states’ boundaries were defined; » they tend to maintain distinct social, economic, and political institutions within their territories; » they typically aspire to remain distinct culturally, geographically, and institutionally rather than assimilate fully into national society; and » they self-identify as indigenous or tribal.
Some countries have legislations that define and recognize specific groups as indigenous. The Constitution of Canada identifies First
Nations (or “Indians”), Inuit, and Métis as “Aboriginal.” In the United States, a variety of treaties and agreements define “American Indians and Alaska Natives.” Beginning in the 1920s, the Soviet government accorded various ethnic groups with a population less than 50,000 the status of “numerically small peoples (korennye malochislennye narody) of the North, Siberia, and the Far East.” At the dissolution of the Soviet Union in 1991, there were twentysix such groups in Russia. By 2005 the number had grown to forty-one. Excluded are nonSlavic national minorities such as the Yakuts, Buryats, and Komi, which have populations in the hundreds of thousands and form their own republics, although the governments of

these republics are typically dominated by Russians. The distinction between “national minorities” and “indigenous peoples” is also made in countries such as Norway, where the Finnish-speaking Kvens are considered to be a minority but not an indigenous group. While ethnic identity is included in the Canadian, American, and Russian censuses, such information is not recorded in the population registries of the Nordic countries. An accurate estimate of the population size of indigenous peoples in all the circumpolar regions is thus not available. Indigenous peoples account for more than 85 per cent of the population in Greenland and Nunavut, but make up only a small proportion in the Nordic countries, with the exception of Finnmark (Fig. 5.8).
Traditional Subsistence Circumpolar indigenous peoples traditionally engaged in subsistence activities that were based mainly on animal resources. Several broad patterns can be recognized. 1. Maritime hunters (e.g., Inuit/Eskimos, coastal Chukchi, Koryaks) engaged in seasonal seal and walrus hunting on ice and in whale hunting from boats. 2. Taiga hunters and fishermen (e.g., Dene, Yukagirs, Evenks, Evens, Enets, Khanty, Mansi, and Kets) based their livelihood on large game hunting and on fishing in rivers and lakes.
3. Reindeer herders (e.g., Yukagirs, Nganasans, Evens) tended large reindeer herds that numbered in the hundreds and thousands. Some groups (Sami, Nenets, Enets) made seasonal trips from the taiga zone to the tundra and back, while others (Chukchi, Koryaks) left the tundra for the sea coast in the summer. Large-scale reindeer herding developed throughout northern Eurasia, although it probably originated independently in different areas.

The lifestyles of indigenous peoples have changed substantially from a century or so ago (Fig. 5.9–Fig.5.11), and the pace of social and economic change has accelerated since the 1950s. Some “traditional” activities are still practised widely, depending on the locality, although this is often for the cultural value of the activity rather than for any economic gains (Fig. 5.12, Fig. 5.13). Despite considerable improvements, indigenous peoples in many circumpolar regions still suffer considerable disparities in their living conditions when compared to their non-indigenous people in the country.

6. Origins and Prehistory
T
hrough statistical analyses of genetic markers, it is possible to show the genetic relationships among the diverse peoples in circumpolar regions. However, extensive intermarriage and adoption of the languages and cultures of neighbouring groups over long periods of time can obscure such relationships.

Genetic Relationships Genetic “distances” measure the degree to which populations share genetic variation. By analyzing so-called classical markers such as blood groups, red cell enzymes, serum proteins, white cell antigens, and immunoglobulins, it is possible to construct a genetic “tree.” One such tree, based on sixty genes, shows the relationship between sixteen Eurasian and North American Arctic groups (Fig. 6.1). Some linguistically close groups are pooled; for example, Even, Evenk, and Buryat are pooled into a “MongolTungu” group, and the Yakut, Dolgan, Tuva, and Altai into a “North Turkic” group. Different trees will result if a different mix of populations or different sets of genetic markers are studied. Modern genomics enables the study of polymorphisms at the DNA level (variation in genetic sequences). By focusing on the rates and patterns of mutations on mitochondrial DNA (mtDNA, inherited by children from their mothers) and the non-recombinant region of the Y chromosome (NRY, passed on from father to son), it is possible to reconstruct human

evolution, especially the prehistoric migrations of populations. Fig. 6.2 shows the distribution of various mtDNA haplogroups among circumpolar peoples. Existing mtDNA and NRY studies have indicated that the Sami had received little genetic flow from Asiatic Siberian peoples. There is no evidence from mtDNA analyses that the Norse had contributed to the Greenlandic gene pool on the maternal side. On the other hand, a study of NRY has shown a high degree
of Scandinavian admixture, as much as 60 per cent, most likely from male Danish colonists rather than the Norse. For indigenous peoples of North America, their Asiatic origin is widely accepted, based on the accumulated genetic evidence from living and past Siberian and North American populations. However, there is still considerable debate on the number and timing of the waves of migrations and their likely routes.

Out of Africa, Into the Arctic The settlement of the Arctic is part of the story of modern Homo sapiens who migrated “out of Africa” some 60,000 years ago. By 45,000 years BP, they had reached Europe. During the next 20,000 years much of Eurasia was colonized, as far north as 60ºN in Siberia and the Urals. Successful occupation of the Arctic required anatomical and physiological adaptation, dietary changes, and technological innovation, particularly in clothing and shelter. The colonization occurred in a series of thrusts and retreats coinciding with climatic oscillations during the Pleistocene Ice Age, which opened and closed habitats. Around 20,000 years BP, (Before Present, set at 1950) with the end of the cold peak of the Last Glacial Maximum, humans were able to maintain a sustained presence above the Arctic Circle. In the west, as the massive Fennoscandia icesheet began to retreat around 12,000 years BP, people moved into southern Scandinavia. By 10,000 years BP, the coasts of western Norway and southern Sweden were occupied as far as 63ºN. Between 10,000 and 7,000 years BP, the Komsa culture thrived on the coast of Finnmark above 70ºN and extended eastward to the Kola Peninsula. In Siberia, the Dyuktai culture flourished about 15,000 years BP around the middle Lena Basin, associated with developing the distinctive “microblade” technology (Fig. 6.3). Around 12,000 years BP, the Sumnagan culture appeared and quickly spread across Siberia and into the tundra. By 10,000 years BP, human settlement extended from Chukotka in the east to the Taymyr Penin-

Studies on mtDNA and NRY rely on the identification of mutations on segments of DNA called haplotypes that are transmitted together. Such haplotypes can be assigned into haplogroups, which correspond to genetic lineages of people who can trace their common origin to the time those mutations occurred and were perpetuated in subsequent generations. The homogeneity of Inuit/Inupiat groups from Alaska to Greenland is evident, among whom the frequency for haplogroup A exceeds 90 per cent. Haplogroup A is also predominant among two Na-Dene groups, but less so among Aleuts and Yupiks in the Bering Sea region. Apart from the Siberian Yupik and Chukchi, there are few similarities between present populations of the Old and New World. It is also evident that the Sami are more European than Siberian in origin.

Across Beringia
From Beringia, further movement to the east was blocked by the Cordilleran and Laurentide ice sheets, which remained a solid mass until around 12,000 years BP. At that time an ice-free corridor opened between the ice sheets and allowed movement southward. This led to the initial peopling of the Americas. An alternative coastal route was feasible earlier, perhaps around 17,000 years BP (Fig. 6.4).
Around 60,000 years BP, the sea level of the Bering Sea was as much as 120 metres below today’s level, exposing the Beringia land bridge. Humans likely occupied Beringia around 15,000 years BP and migrated into North America. Much earlier migrations (by tens of thousands of years) have been proposed. Mammoth bones with signs of human modification have been found in Old Crow Flats and the Bluefish Caves in the Yukon. Some have claimed that these bones are 25,000 to 42,000 years old, but these claims have not been generally accepted. The oldest confirmed site of human occupation is Swan Point in Alaska,
Neo-Eskimo cultures
Humans were probably camping along the Nenana and Tanana river valleys in central Alaska by 12,000 years BP. Between 11,000 and 10,000 years BP, by which time the Beringia land bridge had been completely submerged, a coastal, marine hunting-based culture known
as the American Paleo-Arctic tradition developed around Kotzebue Sound. In the Alaska interior different archaeological traditions and complexes coexisted, which subsisted on freshwater resources and caribou hunting; these were known as the Denali complex, Nenana complex, and Northern Paleo-Indian tradition. Archaeologists assign names to “traditions,” “complexes,” and “cultures” based on the remains found in different sites that reflect a common way of life. The Northern Paleo-Indian tradition is very similar to sites found in southern North America and may represent people who had moved back north in the wake of deglacia-

The Arctic Small Tools tradition originated from northeastern Siberian Neolithic cultures. It was not directly linked to the earlier Paleo-Arctic tradition in the same region. It gave rise to Paleo-Eskimo cultures (such as the Dorset) across the Arctic from about 4,500 years ago. [W. Dallmann, based on McGhee (1996)]

Indians became evident.
Emerging Historic Cultures
In Alaska the maritime-based Arctic Small Tool tradition emerged in the northwest coast around 4,500 years BP. It rapidly spread across the Arctic and developed into different PaleoEskimo cultures (Fig. 6.5). The Dorset culture extended from the central Arctic to Greenland and was adept at winter hunting, including hunting seals in ice holes. It thrived between 3,000 and 1,000 years BP, at which time it was replaced by the Thule culture, with which it coexisted for a short time in some localities.
Global warming about 7,000 years ago ushered in the Neolithic or Late Stone Age in Eurasia. The development of marine-based subsistence promoted the colonization of the Arctic from Norway to Chukotka. Around 2,000 years BP, northern Europe entered the Iron Age. Reindeer herding and plant cultivation were practised. Culturally, the identity of the local populations became recognizable, for example, as Sami and Nenets. In interior Alaska, from 1,500 years BP the archaeological link to present-day Athapaskan

from the Bering Sea coast and had developed innovations such as hunting large sea mammals in open water using skin boats (Fig. 6.6– 6.7). The movements of people and the rise and demise of cultures in the Arctic over tens of thousands of years demonstrated how the physical environment, especially climate change, and the various physiological, behavioural, social, and cultural changes allowed these people to adapt to, and survive in, one of the most challenging habitats on the planet.

7. History and Politics
T
he recorded history of the circumpolar regions is interwoven with the history of the nation-states to which they belong, or used to belong. Tables 7.1 and 7.2 provide a chronology of the major historical events in the circumpolar countries and their northern regions. For most regions, history over the past millennium was marked by exploration, trade, colonization, and de-colonization, although proceeding at different paces.
The Vikings Cometh The seafaring Vikings or Norse from presentday Norway travelled far and wide across the North Atlantic. They settled the Faroe Islands and Iceland in the ninth century AD and Greenland in the tenth century (Fig. 7.1). They established two main settlements on the west coast of Greenland, with about 1,400 people living in each of them. From Greenland, the Norse made forays into the North American continent. Archaeological evidence exists to show that there were interactions between the Norse and the Inuit. For a few years Greenland was home to the Dorset culture, the Thule Inuit, and the Norse. The Norse settlements lost contact with Iceland during the early fifteenth century, and probably died out by AD 1500. The onset of the Little Ice Age around 1450–1500 likely put tremendous stress on what was still a medieval European farming-based society.

New World Explorations The “discovery” of the Americas by Christopher Columbus in 1492 ushered in a new era of European exploration. European knowledge of the Arctic was patchy and fanciful (Fig. 7.2). Beginning in the late sixteenth century, European explorers sailed into the Arctic Ocean in search of the Northwest Passage, although whalers had visited Arctic waters even earlier. A host of explorers are today remembered by various bays, straits, islands, and other geographical features in the Arctic (Table 7.3). The Hudson’s Bay Company (HBC) was granted a royal charter in 1670 with exclusive trading rights in the vast northern hinterland. HBC traders also led significant explorations. The search for ill-fated Franklin expedition in the mid to late nineteenth century generated much valuable knowledge of the Arctic (Fig. 7.3, Fig. 7.4). Concurrent with the search for the Northwest Passage was the search for the Northeast Passage (also called the Northern Sea Route) by Russian and Nordic explorers (Fig. 7.5). Various attempts to reach the North Pole also generated knowledge about the Arctic Ocean and its various archipelagoes.
Colonization and Settlement Northern Canada In northern Canada, the hunting life of indigenous peoples remained largely intact after contact with Europeans. However by the 1860s, Roman Catholic and Anglican missionaries had arrived in the north and openly competed for the allegiance of various communities.
Fig. 7.2 – Mercator map of the Arctic, 1595 The Septentrionalium Terrarum descriptio by Flemish cartographer Gerardus Mercator was the first printed map of the northern hemisphere from the North Pole to 60ºN and indicated a sea route across the top of North America. The North Pole is a massive magnetic rock surrounded by four islands, with waters between them flowing northward into the centre of the Earth. The map also shows the then-recent discoveries of Frobisher and Davis. [Library and Archives Canada]

The HBC sold its land holdings to the newly established Canadian state in 1870, which became the Northwest Territories (NWT). Britain retained control of the Arctic Islands, but transferred them to Canada a decade later. The NWT shrunk in size as new provinces were carved out of it (Fig. 7.6). Yukon became a territory in 1898. The Canadian government entered into treaties with various First Nations as the country expanded. Some Dene groups signed Treaty 8 in 1899 and Treaty 11 in 1921 (Fig. 7.7). The North was deemed unsuitable for agriculture, so the federal government was reluctant to conclude treaties until the incursion of mining prospectors in the Northwest during the late nineteenth century following the Klondike Gold Rush and the discovery of oil at Fort Norman in 1920.

Treaty 8 involved the Slaveys, Dogribs, and Yellowknives south of Great Slave Lake in present-day Northwest Territories (as well as First Nations in British Columbia, Alberta, and Saskatchewan). Treaty 11 covered the Mackenzie River valley region. [INAC]
East Greenland (Tunu) was colonized by the late nineteenth century and North Greenland (Avannaarsua) by the early twentieth century. Denmark adopted a protectionist policy towards Greenland and controlled all traffic with the outside world.
Shortly after the conclusion of these treaties, an influenza epidemic swept through the Mackenzie river valley in 1928, claiming the lives of many elders and profoundly shaking the social stability of the Dene.

In 1721, the Norwegian missionary Hans Egede (Fig. 7.9) arrived in Greenland and established Godthåb (now Nuuk). Other settlements were established along the west coast.

In exchange for the title to their lands, Aboriginal groups were promised hunting and trapping rights, annual payments, various forms of assistance, and the setting up of Indian reserves. None of the territory occupied by the Dene in Yukon and the Inuit was ceded to Canada by a treaty.

During the fourteenth and fifteenth century, northern Fennoscandia attracted traders from the south and from Russia in search of furs and fish. With diffuse national borders in the north, the Sami were often taxed by two or more jurisdictions. Due to diminishing resources in the south, farmers were encouraged to move north, creating conflicts with and displacing the Sami who were forced to move to
the coast. Northern Scandinavia, especially Finnmark, also became strategically important in the geopolitical struggle with Russia over access to the sea and the region’s wealth in minerals, fish, and timber. The border between Norway and Sweden was fixed by the treaty of 1751. The treaty’s Lapp Codicil gave the Sami the right to move freely across the border with their herds while being taxed in only one country, and secured them certain rights in both countries. However, national borders were generally ignored by the Sami. When Finland came under Russian rule in 1809, the Sami in Finnmark were not allowed to use the winter grazing grounds in Finnish Lapland, and in 1889 Russia closed the border between Finland and Sweden for

the movement of herds. Land rights remain the main issue of contention well into the twenty-first century. The Sami continue to face increased pressure for cultural and linguistic assimilation.
Russian Siberia Alaska
and
The Russian conquest of Siberia began when the Cossack known as Yermak Timofeyevich led an expedition beyond the Urals in 1581 (Fig. 7.10). Ultimately, the Tartars and other peoples were brought under the control of the Moscovite state.
In the seventeenth century, Russian control expanded rapidly to the east and northeast of Siberia. The ethnic map of Siberia changed considerably as a result of military campaigns and the migration of people to thinly populated areas fleeing from the yasak (tribute) collectors. The Chukchis were never subjugated militarily, but engaged in trade with the Russians by the end of the eighteenth century. In the late eighteenth century, Russian promyshlenniki (fur hunters) conscripted and exploited Aleut and Eskimos in Alaska, and almost exterminated the sea otter. The first settlement was established in 1784 on Kodiak Island. In 1799, a monopoly in the fur trade was granted to the Russian American Company. Russian influence and interest in Alaska dwindled in the nineteenth century. In 1867, Czar
Alexander II sold Alaska to the United States for $7.2 million. The U.S. government initially did not show much interest in Alaska either, and for years Alaska was referred to as Seward’s Folly, after Secretary of State William Seward who negotiated its purchase. Alaska was granted territorial status in 1912. The U.S. government pursued a policy of assimilation towards Alaska Natives through schools and missions. The gold rush – the most famous one being the Klondike (1897–8) – brought in miners and prospectors. In Siberia during the nineteenth century, special laws were passed to preserve the indigenous peoples’ well-being and way of life and to protect them against arbitrary local authorities and fur traders, but these were rarely observed by government officials.

Fig. 7.10 – Soviet government poster targeting shamans and kulaks, 1931 This poster exhorts people to elect workers and not shamans or kulaks to the local Soviet (committee). Under Stalin’s policy of forced collectivization in the 1930s, Arctic reindeer herders were branded kulaks (rich peasants) because they “owned” thousands of reindeers. Indigenous shamans were also targeted. The policy resulted in the breakdown of indigenous social systems. [G. Khoroshevky]

The Germans adopted a scorched earth policy as they retreated from Finnish Lapland and northern Norway. Much of the population was evacuated. Rovaniemi in Finland and many Norwegian towns were burned to the ground. [Lofoten Krigsminne Museum]
In 1924, during the early years of the Soviet era, the Committee for Aid to Peoples of Far North Areas (or Committee of the North) was created, mainly on the initiative of ethnographer Vladimir G. Bogoraz, with the goal of studying, promoting and protecting the cultures of northern indigenous peoples. The Committee improved living conditions, education standards, and language preservation.
1935. By the 1940s the overwhelming majority of reindeer herds belonged to collective farms (kolkhoz), undermining traditional social structures and economy.
In 1929, private trade was forbidden and a state monopoly for northern resource development was established. Shamans were also the targets of campaigns to discourage traditional beliefs in favour of modern education (Fig. 7.10). The Committee of the North was politically divided and unable to resist these measures or soften their consequences. It was disbanded and some of its members were “liquidated” in
In 1929, “national okrugs” and lower-level “national rayons” were established to administer areas where indigenous peoples predominated. However, real power resided in the central ministries that controlled development.
The North at War The Second World War changed the North. In Europe, the Germans occupied both Denmark and Norway, the latter under Vidkun Quisling, a former defence minister. Sweden was able to maintain its neutrality. Finland thwarted an invasion by the Soviets in 1939. It allied itself

Fig. 7.13 – Construction of the Alaska Highway, 1942 African-American GIs provided the muscle for the construction of this 2,237-km long “highway” under arduous conditions, completing it in seven months.

with Germany and fought the USSR, but eventually made peace with the latter. In northern Norway, the Germans imported 100,000 mostly Soviet and Yugoslav prisoners of war as slave labour to create a system of interconnected road and rail networks up to Kirkenes on the Russian frontier (Fig. 7.11). The worst of the work camps was found in Beisfjord in Nordland county where mortality exceeded 80 per cent. By war’s end, the Germans retreated southward, leaving a trail of destruction in both Finnish Lapland and Finnmark (Fig. 7.12).
The Japanese occupied and were then driven out of two of the Aleutian Islands in 1942. Many Aleuts were relocated to temporary camps in southeast Alaska for the duration of the war, and endured severe hardships. While not directly touched by the war, the rest of the Arctic acquired strategic importance. A chain of landing strips in Alaska and northern Canada provided a transportation link to Europe. The Alaska Highway was also built through the southern Yukon (Fig. 7.13). In Greenland, the Americans built air bases at Kangerlussuaq (Søndre Strømfjord) and Narsarsuaq, which ended the island’s long isolation.
Post-War Developments After the war, radical transformations in the lives of the people occurred across the circumpolar North.
Alaska witnessed a considerable influx of newcomers with new oil and gas developments. In 1959, it became the 49th state (Fig. 7.14). The Trans-Alaska Pipeline from Prudhoe Bay to Valdez was opened in 1977. Oil royalties fuelled much of the state’s economy. In 1989 the oil tanker Exxon Valdez ran aground in Prince William Sound, resulting in an unprecedented environmental disaster. In Greenland a commission was established to suggest reforms and future development. In 1953, it became a county (amt) of Denmark. Extensive infrastructural development transformed a hunting society into a modern society based on the wage economy. Profound social changes accompanied the influx of Danes, whose share of the population increased from less than 3 per cent in the1940s to almost 20 per cent in the 1970s.

62 terning them in residential schools continued throughout much of the 20th century. Language, customs, diet, and spiritual beliefs were discouraged or uprooted by church authorities who ran the 40 schools that operated in northern Canada (Fig. 7.15). Physical, emotional, and sexual abuse characterized the experiences of many individuals who passed through these institutions. The practice finally ended in 1996, followed by a formal apology in parliament and the formation of a Truth and Reconciliation Commission as part of a legal settlement in 2008.

Before the Second World War, the Canadian North was neglected as a barren wasteland with little economic potential. In the 1950s, the pace of change began to intensify. New towns were developed, and the government actively encouraged sedentary settlement so that health, education, and social services could be administered and delivered more easily. Mining activities introduced large numbers of migrant workers from the south. The Cold War hastened the modernization with the construction of radar stations and airstrips (the Distant Early Warning or DEW line, along the 70th parallel). Meanwhile, Canadian attempts to assert sovereignty over the High Arctic led to the relocation of several Inuit communities to more northerly climes, resulting in extreme privation for the families involved. The aggressive assimilation policy of removing Aboriginal children from their parents and in-
Almost in parallel, Soviet ideology also required the cultural integration of diverse ethnic groups into a new modern “Soviet people.” In Siberia, campaigns were launched to enlarge settlements, merge ethnic groups, and discourage the “backward” nomadic way of life. These policies resulted in impoverishment and the loss of traditional livelihoods across the North. Industrial developments by state enterprises sharply increased in the mid-1950s. Uncontrolled natural resources development ignored land rights of indigenous peoples or the negative effects on the environment. Few northern indigenous shared in the economic benefits, although a notable few achieved artistic, athletic, and professional renown.
Towards SelfDetermination In the 1970s, many young Greenlanders began to agitate for greater autonomy. Home Rule (Hjemmestyre) was formally introduced in 1979, with a gradual transfer of responsibility for most public sectors, excluding foreign
affairs, defence, and finance. In 2009, Greenland achieved Self-Rule (Selvstyre), which is close to complete independence. However, its economy continues to be heavily subsidized by Denmark. In Canada, it was not until 1967 that the seat of the NWT government was moved to Yellowknife from Ottawa. The territorial council became fully elected in 1975. In the 1970s a proposal to build a natural gas pipeline in the Mackenzie Valley sparked widespread opposition by indigenous and environmentalist groups. A public inquiry recommended delaying construction until after the settling of land claims. Meanwhile, the Dene experienced a cultural and political renaissance. Since the 1980s, a series of comprehensive land claims have been settled between the Canadian government and various Aboriginal groups (Table 7.4). These agreements generally involve the creation of regional corporations responsible for economic development and for the management and investment of cash settlements. The indigenous people also gained legal title, surface and subsurface mining rights, and exclusive hunting and fishing rights to specific parts of the settlement area. In 1999, Canada’s newest territory Nunavut was born. Statehood in Alaska soon led to conflict over the selection of “vacant, unappropriated or unreserved” lands by the state, lands which were also claimed by Alaska Natives. The discovery of oil in the North Slope in the late 1960s added an element of urgency to the need to settle land disputes. In 1966, the Alaska Federation of Natives was formed, which took the lead in negotiations with the state, leading up to the Alaska
63 Native Claims Settlement Act (ANCSA) of 1971. In return for agreeing to the extinguishment of all claims of Aboriginal title, Alaska Natives were given direct ownership over 10 per cent of the area of the state and $962.5 million in cash compensation. The land and cash would be channelled through regional Native (for-profit) corporations and smaller village corporations (Fig. 7.17). With the disintegration of the USSR in 1991, northern indigenous people became politically assertive and organized. The economic chaos and collapse of state-run enterprises (including reindeer herding collectives) led to a sharp deterioration in the health and wellbeing of the people. The economy began to recover in some areas in the early 2000s. In Scandinavia, the 1960s and 1970s witnessed the awakening of Sami activism and struggle for political rights. In 1979, the hydroelectric power project in Alta, Norway, which dammed and flooded traditional Sami lands, ignited Sami protests. Since then, progress has been made. The establishment of primarily consultative and advisory Sami parliaments in all three countries (Fig. 7.18) safeguard the interests of the Sami in different areas, such as protecting their languages and the use of land and water for reindeer herding. There were symbolic milestones in the proclamation of the Sami anthem and flag in 1986, and the establishment of Sami National Day (February 6) in 1993. The interest in old traditions, Sami languages, and cultural heritage has increased, not least among many young Sami and urbanized Sami.

Circumpolar regions differ in the size of their populations (Table 8.1) and their share of the total national populations. Alaska and the northern territories of Canada constitute less than 0.5 per cent of the total population of the U.S. and Canada, respectively. Greenland’s population is only 1 per cent that of Denmark’s. In contrast, a much higher proportion of the population of Norway (10 per cent), Sweden (6 per cent), Finland (12 per cent), and Russia (5 per cent) reside in their northern regions.
Non-indigenous
n assessing the health of a population, knowledge of the size, composition, and growth of the population itself is required. An accurate enumeration of the population provides the denominator for the rates and proportions that constitute many health indicators. Analyses of the population also help to identify “vulnerable” subgroups such as the elderly, children, and pregnant women who may have special health care needs.
Populations increased in the 1950s across the circumpolar North, but peaked in northern Finland in the 1960s, northern Norway in the 1980s, and northern Sweden and Russia in the 1990s. In northern Canada, Alaska, and Greenland populations continue to grow. Table 8.1 shows the trend in population from 1990 to 2009. Whereas Alaska, northern Canada, and Iceland witnessed substantial growth, many northern Russian regions suffered depopulation, with some losing more than half their populations within twenty years. In only Yamalo-Nenets AO and Khanty-Mansi AO, both of which experienced large scale oil and gas development, have the populations increased. The indigenous population in the Russian North has remained stable; as a result, their share of the total population in the regions has increased.
The increase in Greenland’s population since the early twentieth century is shown in Fig. 8.1. The proportion of the population not born in Greenland has declined from a peak of almost 20 per cent in 1975 to less than 12 per cent in the first decade of the twenty-first century. The population of Chukotka experienced substantial growth since the 1930s, but the population crashed after the demise of the Soviet Union, with the massive out-migration of the non-indigenous population (Fig. 8.2). Between 1960 and 1970, the growth rate of the non-Native population in Alaska was almost twice that of Alaska Natives, due to the high immigration to the state. Since 1990, the situation has been reversed, with the growth rate of the Native population more than twice that of the non-Native population.
Population Density Population densities are shown in Fig. 8.3, and vary from 0.02 in Nunavut to 35 in the Faroe Islands. Within sparsely populated regions, populations are not evenly distributed. Greenland’s inhabitants are concentrated on the southcentral west coast, with only 6 per cent living on the east coast and less than 2 per cent in the Far North. Within each region, the largest city tends to account for a high proportion of the total regional population, from 20 per cent to 70 per cent. Urbanization is widely observed across the Arctic.

Fig. 8.4 – Population pyramids of selected countries and regions [AMAP]
Fig. 8.4 compares the age-sex pyramids of various countries and regions. In general, the population of northern Fennoscandia tends not to differ substantially from its respective national population, and it is characterized by a high proportion of the elderly (65+), between 14 per cent and 18 per cent, which is higher than any other circumpolar region. Compared to the Canadian population, the population of the northern territories is more youthful. The proportion of the population under the age of fifteen is particularly large

In 2000, its median age was twenty-four years, compared to a national one of thirty-five years. The Alaska all-races population is also young, and it occupies an intermediate position between that of the Alaska Native and the U.S. all-races population in terms of the proportion of children and the elderly.

Fig. 8.5 – Location of population centres [W. Dallmann] (a) Alaska
The indigenous population of the Russian North is predominantly rural. In the 2002 Census, only 28 per cent of indigenous people within the territories of their primary residence was classified as urban, a proportion similar to that of the total USSR population in the late 1930s, compared to 73 per cent in the Russian Federation in 2002.

The “settler” and indigenous populations tend to live in distinct communities. In northern Canada, the non-indigenous peoples are concentrated in the cities and large towns, accounting for 40 per cent in Inuvik and Iqaluit to over 80 per cent in Whitehorse and Yellowknife. The majority (more than 60 per cent) of Alaska Natives live in small remote communities, ranging in population from 50 to 5,000. Approximately 85 per cent of the non-Native population lives in larger population centres.

Cities, Towns, and Villages Regional maps showing the location of population centres are provided in Fig. 8.5. There are few large cities in northern Canada or Greenland, with none having a population over 25,000. These regions lie above 60ºN. On this latitude in northern Europe can be found the metropolises of Oslo, Helsinki, and St Petersburg. Even in the northern Scandinavian regions, the largest cities range from 50,000 to 140,000. Even larger cities can be found in the Russian North, with Arkhangelsk having a population over 350,000, and several others in the 250,000–300,000 range. Anchorage is the only North American city (280,000) that is comparable in size.

In comparison with the whole population of Russia, the population of northern natives is considerably younger. The proportion of children under fifteen years of age among northern natives is almost twice that in the country, while the proportion of those aged forty-five and over is only half that observed in all of Russia.
A pictorial tour of the cities and villages of the Arctic is provided by Fig. 8.6 and Fig. 8.7, with a peek inside the tents of reindeer herders’ camps (Fig. 8.8). The increasingly multicultural nature of much of the North is reflected in new types of businesses and places of worship that have been established by immigrants from around the world (Fig. 8.9).

ome circumpolar regions are economic powerhouses while others are poverty-stricken. The land is rich in natural resources, and their exploitation has contributed to enormous economic growth in some regions. Within regions, substantial socio-economic disparities exist, particularly between indigenous and non-indigenous populations, more so in some regions than others.
nn l ma
Fig. 9.1 – Per capita gross domestic product in USD-PPP Different countries use different currencies, and cross-national comparisons require the conversion to some common standard. While the U.S. dollar at market exchange rates (MER) is often used, economists construct “purchasing power parity” (PPP) to adjust for price differences, which may vary considerably among countries, and this conversion is more reflective of the true production volumes of the regions. Note that Arctic-regional PPP-factors have not been developed, and it is the PPP-factors of the national economies that are used, which could be a potential source of bias, especially if price levels are different among regions within countries. [W. Dallmann]
The GDP (or gross regional product when referring to regions) is a well-established economic indicator that measures the goods and services produced within a region within a time period. The per capita GDP provides comparison across regions with different populations (Fig. 9.1). Table 9.1 shows that the GDP of most regions accounts for only a small percentage of their respective national GDP, except in Russia. With only 5 per cent of the national population, Arctic Russia generated 15 per cent of the country’s GDP. Per capita GDP of most northern regions tend to be higher than their countries as a whole, especially regions where there are large-scale oil and gas developments. The highest annual growth rates are found in Russian regions
linked to oil and gas development, such as the Khanty-Mansi, Yamalo-Nenets, Evenkia, and Nenets AO. However, it is also in Russia where regions with negative growth rate are found. The GDP has shortcomings as a measure of economic well-being, especially its failure to account for income distribution within the population. For northern regions, there are additional problems: » A sizable proportion of the workforce consists of seasonal workers from outside the region, and many firms are owned by non-residents and their profits leave the region. The GDP thus does not reflect the true income accruing to the residents of the region. On the other hand, a region such as Alaska generates billions of dollars of investment income outside the state which is not captured by the state’s GDP. » Many regions are subsidized by the national governments. Such spending are included in the GDP, yet does not strengthen the regional economy. » Subsistence activities, especially by indigenous people, may not be counted at all, or inconsistently valued. » Northern economies that are dependent on a few natural resources (e.g., oil and gas) may be subject to substantial year-to-year variation due to market price fluctuations.

The Northern Economy
[Econor II, based on 2005 data]
The relative sizes of different industries are compared in Table 9.2. The modern economy of circumpolar regions is predominantly resource-based (Fig. 9.2), although in many regions there is a mix of the traditional and the
new (Fig. 9.3). Across the North, there is an ongoing struggle between different levels of governments, Natives and non-Natives, and environmentalists and developers over the balance between resource development and protection of the fragile Arctic environment.
Oil and gas (Fig. 9.4) dominate the economy of Alaska and Arctic Russia. Oil wealth allows Alaska to not levy a state income tax. The Alaska Permanent Fund, established in the 1970s from royalties, issues periodic pay-outs to residents. Norway’s oil production is mostly in the

79 North Sea and other fields further to the south of its Arctic regions. In northern Canada, mining (Fig. 9.5), especially diamonds, is a major contributor to its economy, while oil and gas production has declined since 2000. Greenland may possess considerable oil reserves and explorations are underway on its west coast. Under Self-Rule, it will share resource revenues with Denmark according to a formula, while it is being “weaned off ” Danish subsidies. Fish and other edible species from the sea (such as shrimps) are other resources that sustain the economy of Greenland, Iceland, and the Faroe Islands. Fishing remains important in coastal Norway but insignificant in northern Sweden or Finland. The health of the fishing industry (Fig. 9.6) is dependent on both the volume of the catch and the market price. For climatic reasons, agriculture does not play a major role in the economy of most northern regions (Fig. 9.7). Forestry and the pulp and paper industry (Fig. 9.8) are important in northern Finland and Sweden. Hydroelectric power generation is well developed in northern Sweden and Norway, where most major rivers have been dammed (Fig. 9.9). Northern Finland has a strong manufacturing sector and is a world leader in mobile phone technology, centred at Oulu, where close industry–academic partnerships have been successful incubators for advanced technology development (Fig. 9.10). The manufacturing sector in northern Scandinavia has benefited from better infrastructure, especially road and rail transportation, and shorter distances to markets.

Shipping is important for some coastal communities, while air links are particularly critical for all remote regions (Fig. 9.11). The services industry is larger than either primary or secondary production in all regions except northern Russia. It accounts for the largest share of the economy in Iceland and northern Norway. Tourism is an emerging industry, and cruise ships ply the Arctic waters (Fig. 9.12). Iceland became the harbinger of the global economic crisis in late 2008 when its banking sector collapsed.
Certain activities engaged in primarily by indigenous peoples, such as hunting and trapping for fur and meat (Fig. 9.13) and handicrafts (Fig. 9.14), are important culturally although they are not substantial in economic terms other than for subsistence. Reindeer husbandry is the main source of income for indigenous peoples in several Russian regions.
(b) Muskox hide
Some northern regions benefit from substantial transfers and subsidies from the national government. In northern Canada, over 80 per cent of public revenues are derived from the federal government. Subsidies from Denmark amount to 10 per cent of public expenditures in the Faroe Islands and almost half in Greenland. (c) Seal skin

Socio-economic Status
Sculpture of reindeer herding from Magadan. [W. Dallmann]
As components of socio-economic status (SES), income, education, and employment are defined and measured differently in circumpolar countries and they have different contexts. UNESCO has devised an International Standard Classification of Education to facilitate comparisons across vastly different educational systems. Fig. 9.15 compares the proportion of adults who had attained only elementary education according to SLiCA. It can be seen that Canadian regions fare worse than Greenland or Chukotka. A circumpolar perspective on tertiary education is provided in Fig. 9.16. Within the North, indigenous peoples tend to fare worse in their SES than non-indigenous peoples, especially in Alaska, northern Canada, and Russia. While Alaska and Yukon report better SES than the national averages, the disparities relative to the country as a whole widen as the proportion of indigenous peoples increases. This situation reflects the in-migration of nonindigenous peoples seeking employment; those who are no longer employed or retired tend to leave the North. The disparities with the rest of Canada are worst in Nunavut, which has only a small proportion of non-indigenous peoples. The Canadian Department of Indian and Northern Affairs developed a composite index of community well-being (CWB) based on aggregate income, education, housing, and labour-

In the Canadian North, the mean score was 62.0 for 31 Inuit communities, 66.2 for 35 Dene communities, and 81.6 for 15 predominantly non-Aboriginal communities. In the rest of Canada, the mean score was 74.2, (Fig. 9.17). In Greenland, there are income disparities between individuals born outside the country and native Greenlanders, and also between residents of Nuuk and other towns. Education levels continue to improve. In the first decade of the twenty-first century, the number of individuals with post-secondary education, including vocational, teacher’s training and university education, has tripled. The level of education is generally high in northern Norway, Sweden, and Finland, and higher for women than for men. The proportion of people with university education is lower in northern Scandinavia, particularly for men, than in the country as a whole. The unemployment rate shows a west-east gradient with the lowest rates in Norway and the highest in Finland. The average annual income is also highest in Norway and rather similar in Sweden and Finland. Modest disparities do exist between the northern regions and the national averages. Socio-economic data for the Sami people of the Nordic countries are not readily available.
In Norway, economic statistics are collected for the “Sami Settlement Areas,” which are inhabited by Sami (but not exclusively) and who are eligible for financial support from the Sami Development Fund (SUF), which is administered by the Sami parliament. Compared to Norway as a whole and to other northern non-SUF areas (mainly urban), the Sami areas report lower per capita income in all categories except for child allowance.

As part of a health study on Swedish Sami, the annual net income between 1970 and 2000 for Sami reindeer herders and non-herders were compared to that of a demographically matched non-Sami population, and of Sweden as a whole. Among men, there were small differences in the median net income between non-herding Sami and non-Sami, whereas the income for the reindeer-herding Sami men was considerably lower throughout this period. Among women, the differences among the four groups were small. Since the late 1980s, the net income of reindeer-herding Sami women has exceeded that of their men, mainly through wage employment. In terms of education, the proportion of women with tertiary education was highest among reindeer-herding Sami. Reindeer herding Sami men, on the other hand, reported the lowest proportion of tertiary education and the highest proportion of those with only primary education.

partial picture of health. There is, however, no overall measure of morbidity. Some measures depend on contact with the health care system while others are based on self reports in a survey setting. Disease surveillance through special registries permits the determination of the incidence of selected diseases. Only a limited number of disease registries, usually the communicable diseases and some chronic diseases such as cancer, exist in circumpolar countries.
Sources of Data Health can be represented by an iceberg, to use an Arctic analogy. Above the water, representing the most severe consequences of ill health, is mortality. Circumpolar countries have welldeveloped statistical agencies with mortality databases that record the number and causes of deaths, and also some demographic information about the decedents.
Health surveys can collect information on health conditions that do not result in any kind of formal contact with the health care system. In addition, they can capture “positive” health, quality of life, and health practices and beliefs, among other things. There have been many health surveys in circumpolar countries. Some are large-scale national surveys, which include
As most sicknesses do not result in death, it is evident that mortality can only provide a Fig. 10.1 – Life expectancy at birth in circumpolar countries and regions [K. Young]
samples from the northern regions, while others are specifically designed for residents of the North, especially its indigenous peoples. These surveys range in complexity from those comprised only of interviews to comprehensive ones involving physical measures, clinical assessments, and laboratory tests. A multinational circumpolar effort called the Survey of Living Conditions in the Arctic (SLiCA), is based on interviews and covers the Inuit/Inupiat regions of Alaska, Canada, and Greenland, the Sami in Fennoscandia and the Kola Peninsula, and the indigenous people of Chukotka. A major problem with international comparisons is the standardization of concepts, definitions, methods, and data management.

Mortality Differentials A commonly used summary health indicator in international comparisons is life expectancy at birth (LE0), which is based on the mortality experience of a population. Among the circumpolar regions, the difference in LE0 between the regions with the highest (Iceland) and the lowest (Koryak AO in Russia) is thirty years in men and twenty-two years in women (Fig. 10.1). A similar pattern is observed in the all-cause mortality rate (Fig. 10.2).

Alaska’s LE0 is the same as that of the United States, but for Alaska Natives there is a drop of about five years. In Canada, there is a difference of eight years between the LE0 of Nunavut residents and the Canadian average, and less of a gap in the other two territories. Greenland’s LE0 is about ten years shorter than Denmark’s. In Fennoscandia, there is little difference between the northern and the national LE0.

Russia is suffering an unprecedented health crisis. The national male LE0 is about sixty years, while some northern regions are even worse off. There is about a ten-year difference between the LE0 of Russian Arctic indigenous people and the national average, although the gap has narrowed since the 1970s, with the whole country having suffered reverses during the early 1990s (Fig. 10.3).

Note: Age-standardized mortality rates (ASMR) adjust for differences in the age distribution of the populations being compared by applying the observed age-specific mortality rates for each population to a “standard” population. This is called the “direct” method. In this atlas, unless otherwise specified, the standard population used is the European Standard Population published by Eurostat. It is a hypothetical population of 100,000 people with the following age distribution: Age group

Self-Rated Health Overall health status can be assessed in a health survey by asking respondents to rate their own overall health, typically into categories of “excellent,” “very good,” “good,” “fair,” and “poor.” As a health indicator, self-rated health is inexpensive and simple to obtain. More importantly, it has been shown by many studies in a variety of populations to be a valid indicator of health, with the ability to predict future health outcomes such as mortality, mor-

bidity, and use of health services. In providing answers, respondents may take into account their full array of health problems and symptoms, some of which are not yet medically detectable. Individuals who perceive their health to be poor may engage in behaviours and patterns of health care use (or non-use) which may adversely affect their health. Finally, selfrated health may also encompass the presence or absence of internal and external resources which affect their ability to cope with future illnesses. Some circumpolar data are available from SLiCA (Fig. 10.4). Overall, indigenous residents in Chukotka are least likely to report good or excellent health when compared to their counterparts in other regions. This is a consistent finding in most other health indicators collected by SLiCA.
Human Development Index To capture more broadly the level of well-being of a population, international agencies such as
2005

the United Nations Development Programme (UNDP) have created the “human development index,” which combines statistical measures of health, education, and standard of living. Health is represented by life expectancy at birth; education is a composite of the mean number of years of schooling of adults and school enrolment; and standard of living by the per capita gross national income. Since the 1980s circumpolar countries, excepting Russia, have consistently been at the top end of the range of countries in the world (Fig. 10.5). In 2010, Norway, the United States, Canada, and Sweden ranked within the top ten and Finland, Iceland, and Denmark within the top twenty, while Russia ranked sixty-fifth. Within Russia itself there is regional variation, with KhantyMansi AO and Yamalo-Nenets AO scoring highest, well above the national average (Fig. 10.6). In the following chapters, specific health problems affecting circumpolar regions are discussed in detail.

elatively large numbers of children and youth in a society increase the need for services such as housing, education, health care, and employment.
As Fig. 11.1 shows, the youthfulness of the population varies across the circumpolar world. The highest proportions of the underfifteen population are found in Nunavut and the Northwest Territories, Greenland, and Alaska, all regions with a high proportion of indigenous people. In contrast, the percentages of the population under fifteen years of age among the northern regions of Norway, Sweden, and Finland are very similar to the percentages in their national populations. Children are a source of joy to their families and communities, and children grow up to become adults (Fig. 11.2). Maintaining the health of children is a priority in all circumpolar countries and regions.
Infancy The infant mortality rate (IMR) is a sensitive indicator not only of child health, but also of the overall health status of a population. It can be divided into the neonatal (day zero to day twenty-seven) and post-neonatal (day twentyeight up to the completion of the first year of life) periods. IMR varies from less than five per 1,000 live births in the Nordic countries to over ten in Nunavut and Greenland, and over twenty in some Russian regions. There is little difference between the northern regions of the

Nordic countries and the rest of these countries (Fig. 11.3). There is a thirty-year time lag between the IMR of Greenland and Denmark (Fig. 11.4). Control of infectious diseases through the provision of safe drinking water and immunizations has contributed much to the dramatic decrease in post-neonatal mortality rates (PNMR). In the Nordic countries, Canada, and the United States, PNMR comprises about 30 per cent of infant deaths. The proportion is much higher for Alaska Natives and those in the northern territories of Canada, about 50– 60 per cent.

While immunization schedules vary by country with regard to vaccines included and age groups targeted, most jurisdictions include diphtheria, pertussis, tetanus, polio, measles, mumps, rubella, and Haemophilus influenzae type B during the first year of life.
tices vary widely – often failing to distinguish whether infants are exclusively breastfed, when breastfeeding is initiated, and for how long is breastfeeding continued after birth.
Breastfeeding protects the infant from gastrointestinal, respiratory, and middle ear infections and appears also to enhance cognitive development. Breastfeeding rates in Scandinavia are very high, and there are little differences between rates in the northern regions and the national average. Internationally comparable data are difficult to obtain, as reporting prac-
While diseases such as middle ear infections are important in this age group (Fig. 11.5), children also develop chronic diseases such as cancer. Age-standardized cancer incidence rates for children and youths aged zero to nineteen years show that Greenland had the highest cancer incidence rate whereas northern Canada and Finland had the lowest rates.
Childhood
91
Childhood is also a vulnerable period for emotional, physical, or sexual abuse and emotional or physical neglect. Greenland has the highest reported prevalence of child abuse, but given that the definition of child abuse varies be-
tween jurisdictions, meaningful comparisons among countries are not possible.
120
Promoting the health of children also requires society to invest in interventions outside the health system, such as early childhood education, childcare, safe neighbourhoods, and accessible recreation facilities (Fig. 11.6).
100
Adolescence and Youth Many health risk behaviours that have a longlasting impact on adult health are initiated during adolescence and youth, such as smoking, alcohol use, and drug use. Comprehensive and comparable data for the circumpolar regions are lacking. Fig. 11.7 presents some key findings from the Youth Risk Behaviour Survey, a school-based survey of Alaskan children in Grades 9-12. In general, these findings do not differ substantially from national rates.
Infant deaths (per 1000 livebirths)
The two types of diabetes, type 1 and type 2, affect Arctic populations differently. Nordic countries are at high risk for childhood type 1 diabetes, and Finland has the world’s highest incidence. The rate continues to increase. However, within Finland itself, the highest risk areas are located in central Finland while Lapland is at relatively low risk. Meanwhile, type 2 diabetes is an increasingly serious problem among the indigenous people of North America. The increasingly lowering age of onset of the disease in childhood and adolescence among the First Nations population in southern Canada has not been observed in the Arctic.

Alcohol abuse is one component of a cluster of youth risk behaviours that also includes the abuse of other substances and risky sexual behaviours. For example, solvent use includes sniffing of gasoline, glue, and aerosol propellants. Prenatal maternal or childhood solvent abuse can disrupt normal childhood nervous system development and acute high-dose exposures can cause death.

Most smokers become addicted as teenagers. In Canada, the prevalence of smoking (either daily or occasionally) among teens aged twelve to nineteen is higher in the North than in the rest of the country. The Nunavut rate (about 45 per cent) is higher than anywhere else in the circumpolar North.
Adolescents and youths are particularly vulnerable to injuries, both intentional (suicide and assaults) and unintentional (accidents). Suicide rates are much higher among Alaskan and Canadian Arctic indigenous people and in residents of Greenland than the rates among Americans, Canadians, and Danes (see chapter 18). Most deaths resulting from unintentional injury occurs among adolescents and youths, among whom risk-taking behaviours tend to be more prevalent – particularly in males. Unintentional injury death rates are consistently higher among males than females.

(b) Age-specific fertility rates in Russia.
Within regions, the indigenous fertility rate tends to be higher than that of the total population, as illustrated by the crude birth rate in Alaska (Fig. 12.3), although there has been a downward trend in all populations since the 1960s. In Greenland during the late 1960s the crude birth rate was halved over a ten-year period as a result of a countrywide birth control campaign, with intrauterine devices being adopted by about half of the female population of reproductive age.
The age-specific fertility rate of selected circumpolar regions is shown in Fig. 12.4. It can be seen that Nunavut, Greenland, and Alaska (especially among Alaska Natives) have high birth rates in the fifteen to nineteen and twenty to twenty-four age groups. However, the Nordic regions report the highest rate at ages twenty-five to twenty-nine. While fertility is depressed in all Russian regions, those regions in European Russia have the lowest ASFR in all age groups.
jor cause of sudden infant death syndrome and a significant cause of asthma.
Traditionally, many ethnic groups in the Russian North practise late marriages, resulting in comparatively low fertility rates. Modern methods of family planning have spread slowly in the whole of Russia, particularly in the North. The typical methods used are intrauterine devices and induced abortions. In Russia about 60 per cent of pregnancies end in legal abortions – among the highest in the world. The frequency of abortions among northern indigenous women is about one-quarter to one-third that of the national average.
Prenatal Care
Prenatal maternal alcohol use is toxic to the developing fetus and infant and is a major cause of birth defects and developmental disabilities. No safe level of prenatal maternal alcohol consumption has been identified. Severe outcomes include early fetal death (spontaneous abortion) and structural, growth, and functional abnormalities variably categorized as fetal alcohol syndrome (FAS), fetal alcohol effects (FAE), and alcohol-related neurodevelopmental disorder (ARND).
Access to prenatal care is a major predictor of adverse pregnancy outcomes such as low birth weight, stillbirth, and infant mortality. Maternal behaviour during pregnancy has a major impact on fetal and infant heath. Prenatal smoking causes fetal death, intrauterine growth retardation, preterm birth, and cardiac (and possibly other) birth defects. Prenatal maternal smoking and post-natal infant exposure to environmental tobacco smoke is a ma-
The prevalence of smoking and alcohol use during pregnancy and their differential impacts on infant mortality among Alaska Native and non-Native women is shown in Fig. 12.5. In Scandinavia, Sweden reported the lowest rates (about 10 per cent), while Norway’s was twice that. The prevalence of smoking tends to decline towards the end of the pregnancy. In Norway, rates for the northern counties are generally higher than the national rate.

In addition to tobacco and alcohol, prenatal maternal volatile substance abuse has been linked to prenatal growth restriction, cognitive, speech, and motor deficits, and craniofacial abnormalities similar to those of fetal alcohol syndrome.
Perinatal Mortality An overall measure of pregnancy outcome is the perinatal mortality rate, which combines stillbirths (fetal deaths) and early neonatal deaths (under seven days of life). Such a measure is sensitive to the care of the mother during pregnancy and delivery, and also the care of the newborn. As shown in Fig. 12.6, Greenland and northern Canada have the highest perinatal mortality rates.
Prematurity Because preterm infants have immature body systems, they face increased risks of respiratory complications, infections, cerebral palsy, and other neurodevelopmental deficits that can lead to long-term disabilities.

The preterm birth rate varies considerably among circumpolar regions, with Iceland and the Faroe Island having the lowest rates (less than 5 per cent) and Alaska Natives and Nunavut (about 12 per cent) having the highest rates. Women in the rest of the Arctic have intermediate preterm birth rates (6–8 per cent). Many Arctic indigenous populations lack access to early ultrasound examinations. In the absence of uniform estimations of gestational age, preterm birth rates may not be strictly comparable among circumpolar countries. Accurate gestational age data are also needed to differentiate preterm births from intrauterine growth retardation. Improving access to prenatal ultrasound services across circumpolar regions is an important component of maternal health services.
Low Birthweight Low birthweight (LBW), defined as birth weight lower than 2,500 grams, comprises two distinct subgroups: preterm infants with normal birth weights for their gestational ages and

infants with intrauterine growth retardation. Higher LBW rates among sub-populations reflect disparities in socio-economic status, decreased access to prenatal care, and the prevalence of risk factors such as maternal smoking, inadequate diet, and alcohol consumption. The lowest proportion of LBW births was reported in Iceland (less than 4 per cent), while Nunavut (8 per cent) had the highest. Note that the national rate in the United States was also quite high – however, there was substantial difference between blacks and whites, with the former reporting almost twice the LBW rate of the latter.

ntil the middle of the twentieth century, infectious diseases were major causes of death in circumpolar regions. Since then, mortality rates have decreased markedly, although the overall burden of infectious diseases in the Arctic remains high – and higher than in southern populations. There are also infections that are particular to the Arctic because of its physical environment and the cultural practices of its inhabitants.
Considerable variation in the incidence of tuberculosis (TB) exists across circumpolar regions (Fig. 13.1), with Nunavut, Greenland, and some Russian regions reporting the highest rates. The disparities are enormous, with Koryak AO having almost 100 times the TB rate of Iceland and the Faroe Islands. TB disproportionately affects the Inuit in Canada, Alaska, and Greenland and its incidence reached its peak in the 1950s. The decline in the incidence of the disease has been impressive (Fig. 13.2), although a substantial gap still exists between the indigenous and nonindigenous populations in these regions. It was during the 1950s that large-scale intervention programs were initiated to combat
TB. These programs laid the foundation of the modern public health system in these regions. Hospitals such as the Queen Ingrid’s in Nuuk began as TB sanatoriums. Medical ships such as the C.D. Howe patrolled the central and eastern Arctic (between 1950 and 1969) and the Misigssut along the west coast of Greenland (from 1955 to 1971) to conduct X-ray surveys and vaccinations. In Canada, the TB control policy of the time created considerable hardship among the Inuit due to their prolonged hospitalization in southern sanatoria and long separation from their families, their communities, and the Inuit way of life. The practice of hospitalizing TB patients for treatment has largely been abandoned in most countries, although it still persists in some regions (Fig. 13.3).

Respiratory Tract Infections Upper and lower respiratory tract infections (RTI) cover a wide spectrum of infections, from common colds to severe, life-threatening pneumonia. They are important causes of childhood mortality, hospitalization, and physician visits. Crowding, passive smoking, and poor indoor air quality facilitate the spread of infection. Fig. 13.4 shows the variation in mortality from respiratory diseases (including both infectious and non-infectious causes) across circumpolar regions. In Nunavut and Alaska the rates of hospitalization for severe lower RTI in Inuit infants (mainly due to the respiratory syncytial virus) exceed 300 per 1,000 in the Baffin region and 250 per 1,000 in the Yukon-Kuskokwim Delta.

There they are put on a special diet with lots of fresh fruits, milk, and eggs. The children usually stay for three to six months but may be there as long as two years. Over 90 per cent of the inpatients are indigenous. [K. Young] ASMR - respiratory diseases (per 100,000) 1 < 50 2 50-99 3 100-170 4 >170

Patients often require mechanical ventilation in intensive care units, and readmissions are frequent. Some also suffer from long-term chronic lung infections such as bronchiectasis. Sk

Sexually Transmitted Diseases Sexually transmitted diseases include gonorrhea, syphilis, acquired immunodeficiency syndrome (AIDS), and infections caused by Chlamydia trachomatis, herpes simplex virus, human papilloma virus (HPV), Trichomonas, and several less common pathogens. Syphilis occurs only sporadically, although there had been epidemics in Greenland in 1976–7 and 1987 and the Yukon in 2000–3. Gonorrhea and chlamydial infections are far more com-

mon, highly transmissible, and if left untreated can lead to pelvic inflammatory disease, ectopic pregnancy, and infertility in women. Among circumpolar regions, Greenland is the hotspot for gonorrhea (Fig. 13.5). Its incidence increased steadily during the 1950s and 1960s. A systematic intervention strategy that included partner tracing and treatment has resulted in an impressive decline, but the current level is still >200 times higher than the rate in Denmark. The pattern of chlamydia infection tends to parallel that of gonorrhea, with Greenland, Nunavut, Northwest Territories, and Alaska reporting the highest rates.
Given the high rates of STDs in these regions, there was much fear of the human immunodeficiency virus (HIV) spreading to the Arctic when the epidemic began in the 1980s. This has not happened, but HIV/AIDS nonetheless represents a major public health threat. The distribution of risk groups – men who have sex with men, heterosexual contacts, and injection drug users – vary across regions. There is a long incubation period between HIV infection and the onset of the clinical symptoms of AIDS. Most jurisdictions report these two entities separately, but the extent of HIV testing in the population varies, and cross-national comparisons should be made with caution. The prevention of HIV/AIDS and other STDs requires behavioural change related to sexual practices, such as condom use and limiting one’s number of partners.
Hepatitis Viral hepatitis is a group of liver infections caused by five viruses, labelled A to E, of which
(b) Electron micrograph of Hepatitis B virions [CDC]
A, B, and C are the most prevalent. Hepatitis A virus (HAV) is transmitted by the fecal-oral route. It is rarely fatal and usually self-limited, and it renders life-long immunity. Hepatitis B virus (HBV) is transmitted by sexual contact or via the bloodstream. It may result in lifelong immunity, but some cases progress to a chronic state with the virus free in the blood. A minority of chronic HBV-infected persons may later develop liver cirrhosis and/or primary liver cancer. Hepatitis C virus (HBC) is
99 transmitted via contaminated blood or direct needle inoculation and may also result in clinical hepatitis, cirrhosis, and liver cancer. Little data exist on the extent of HBC infection in the Arctic. Serosurveys in various circumpolar regions have consistently shown that some 50–70 per cent of the adult population had previously been exposed to HAV. Epidemics have occurred periodically. In Alaska, universal childhood HAV immunization among all children age two and eighteen years, initiated in the 1990s, has resulted in the rate of acute HAV falling from the highest in the country to the lowest within ten years. There were no similar campaigns elsewhere and the reduction of HAV epidemics in these places is likely due to improved sanitation. In the 1970s it became apparent that HBV infection was endemic in some Arctic indigenous populations, especially in Greenland, and less so in Canada and Alaska. Rates of longterm sequelae of HBV infection, liver cirrhosis, and liver cancer are high among Alaska Natives, but lower than expected in Canada and Greenland. Different preventive actions have been taken in circumpolar regions, but the most dramatic impact was observed in Alaska, where a program of mass HBV vaccination (which includes all infants) was instituted in the 1980s (Fig. 13.6).
Invasive Bacterial Diseases The Inuit are at a particularly high risk for several invasive bacterial diseases (Fig. 13.7), including infection by Streptococcus pneumoniae (pneumococci), which causes pneumonia,
bacteremia, septic shock, and meningitis. It has been estimated that 80 per cent of invasive pneumococcal disease occurring in Alaska, northern Canada, and Greenland are potentially preventable with the use of polyvalent pneumococcal vaccines. Haemophilus influenzae can cause respiratory tract infections, meningitis, and septic arthritis. Among the 6 serotypes (a-f), Haemophilus influenzae type b (Hib) was the most common cause of childhood meningitis prior to the introduction of childhood conjugate vaccines in the early 1990s. Rates of invasive Hib disease among Alaska Natives were once among the highest in the world, but have rapidly decreased since the introduction of universal infant immunization. The disease has been virtually eliminated in the non-Native population and the rest of North America. Another cause of bacterial meningitis is Neisseria meningitides (meningococci). Epidemics occur sporadically. The majority of cases are caused by serogroups B and C. Current vaccines only prevent against Group C infections.

Helicobacter pylori infection can cause stomach ulcers and increases the risk of chronic gastritis and certain types of stomach cancer. As the risk of stomach cancer is higher among the Inuit than other populations, there is strong interest in studies on H. pylori in the Arctic. Blood loss from chronic gastritis due to H. pylori infection could contribute to iron deficiency anaemia. However, treatment of the infection with antibiotics has not been shown to improve the anaemia.

Zoonoses and Parasitic Infections With their hunting traditions and subsistence based on wild game, Arctic indigenous peoples are at increased risk of zoonoses and parasitic infections acquired from infected meat. Zoonoses are diseases caused by organisms that are usually present in animals but can be transmitted to humans. Trichinellosis is caused by ingestion of the nematode worm Trichinella (Fig. 13.8). T. nativa is widespread in Arctic wildlife and is freeze-tolerant. Humans can be infected from the meat of bears, walruses, and seals. The disease occurs sporadically but outbreaks have been reported in Alaska, Canada, and Greenland, sometimes involving over 100 cases. Despite the declining frequency of outbreaks,
seroprevalence studies still show a high proportion of people with past exposure to the parasite, especially in hunting districts and among older persons. A number of once-common zoonoses have greatly decreased in significance due to lifestyle changes in circumpolar populations. Echinococcus granulosis and E. multilocularis are common tapeworms in foxes and dogs, and in humans they cause the highly lethal alveolar hydatid cyst disease. The disease is becoming less common as dog-teams are being replaced by snowmobiles in many parts of the Arctic (Fig. 13.9). Botulism is caused by ingestion of a neurotoxin produced by the bacterium Clostridium botulinum, which grows in meat and fish stored under anaerobic conditions. Botulism results in muscle paralysis, eventually leading to respi-
Fig. 13.10 – Traditional method of fermenting meat [A.Parkinson]
ratory arrest. In the Arctic, traditional processing of meat and fish involves fermentation by anaerobic storage at low temperatures (above freezing) without salting. This has led to occasional outbreaks of botulism in Inuit regions. A shift in fermenting techniques towards the use of plastic bags and plastic containers, which facilitates growth of anaerobic bacteria, may have contributed to the increasing incidence of botulism observed in Alaska (Fig. 13.10). Parasitic and zoonotic infections are highly dependent on climate. There is a concern that climate changes in the Arctic affecting temperature, humidity, flooding, and biodiversity may increase the incidence of these infections in humans.

ancer refers to the uncontrolled growth and spread of abnormal (malignant) cells. It is generally classified according to anatomic site (i.e., where the “primary” cancer originates, to be distinguished from “secondary” sites where it may have spread). However, within each site there may be several different histological types (such as squamous cell carcinoma, adenocarcinoma, etc.). Cancer may be detected at different stages in its natural history, often a reflection of the quality of preventive and diagnostic health services. Different risk factors have been identified, such as tobacco, diet, radiation, viruses, etc., although the causes of most cancers are unknown.

Incidence and Mortality
Inuit Cancer Patterns
Fig. 14.1 – Cancer incidence from all sites
The most accurate way to measure cancer incidence is through a population-based cancer registry. Not all countries or regions have cancer registries. Fig. 14.1 compares cancer incidence among men and women in circumpolar regions, with the notable exception of Russia, where there is no national registry and few regional ones. The highest incidence rates are found in Nunavut, Greenland, and Alaska.
An international review of cancer among Inuit in Alaska, Canada, and Greenland reveals that cancers (all sites combined) have increased in all Inuit regions over a thirty-five-year period from 1969–2003 (Fig. 14.3). The increase is particularly marked for lung and colorectal cancers, while the presence of cervical cancer has declined. For the 1989–2003 period, the overall risk of cancer among Inuit men and women was not in excess of those among nonInuit. Inuit continue to be at extreme high risk for certain so-called traditional cancers, such as nasopharyngeal and salivary gland cancer (Fig. 14.4). However, Inuit today also have the world’s highest incidence rate of lung cancer (Fig. 14.5).
(left) Rates are age-standardized to the “world” population, per 100,000 per year.
Because cancer is highly lethal, cancer mortality rates are often used where incidence data are not available. It should be noted that mortality rates also reflect the availability and effectiveness of treatment services (Fig. 14.2). It is evident that the highest mortality rates are reported in Nunavut and Greenland, reflecting their high incidence rates, but also suggestive of poorer rates of survival.

A relative risk of 1.0 means there is no difference in incidence between the Inuit and non-Inuit in this case represented by U.S. whites as recorded in the Surveillance, Epidemiology and End Results (SEER) of the U.S. National Cancer Institute. Bars above the horizontal line represent cancer sites for which the Inuit are at higher risk than U.S. whites. Fig. 14.4 – Circumpolar Inuit cancer: Relative risks

Although enhanced quantities of the isotope Cesium-137 have been found in lichen and reindeer meat, as well as in whole-body content among reindeer herders, there has been no detectable excess of either leukemia or thyroid cancer, which are radiation-sensitive. The incidence of prostate, lung, breast, and colorectal cancer is lower among the Sami than in the rest of the population. These results suggest that radiation doses received by the reindeer-herding Sami were too small to have substantially affected cancer incidence.
Control and Prevention The control of cancer requires multiple strategies directed at different stages in the natural history of the disease. Primary prevention efforts directed at eliminating smoking, reducing heavy alcohol use, increasing dietary fruits and vegetables, maintaining healthy weights, and promoting physical activity would have benefits in preventing cancer and other health problems. It should be recognized that, given the long lag time in the development of cancer, even if smoking or other risk behaviour is dramatically reduced today, it would be decades before any impact on cancer rates could be observed.
Early detection of cancer through organized screening is dependent upon a well-organized health care system. The Arctic has lagged behind in such efforts. In Greenland, a centralized, population-based program for cervical cancer screening was not implemented until 1999, decades after its implementation in Denmark. Prior to 2000, Nunavut was the jurisdiction with the lowest screening participation rate in Canada. However, by 2005, the proportion of women in the three northern territories aged eighteen to sixty-nine who had had at least one Pap test during the preceding three years exceeded the Canadian national average. Clearly, intensive promotion of preventive services in the target population can achieve an increase in participation. Definitive diagnosis of most cancers requires sophisticated and complex tools (such as computed tomography, magnetic resonance imaging scans, endoscopy, surgical pathology, and biomarkers), and by necessity such tools are concentrated in regional centres. The unique challenge of health care delivery in the Arctic is the need to strengthen primary health care at the community level to ensure that possible cancer patients are promptly identified and referred for further investigation. The treatment of cancer is also highly specialized and includes surgery, chemotherapy, and radiotherapy. Cancer patients are often required to travel long distances for treatment.

Due to the fact that northern Scandinavia was heavily exposed to nuclear fallout from Soviet nuclear tests in the Kola Peninsula during the 1950s and 1960s and the Chernobyl accident in 1986 (Fig. 14.6), concern was expressed regarding the risk of cancer among the Sami populations of Norway, Sweden, and Finland.
The viral etiology of human papilloma virus in cervical cancer and hepatitis B virus in hepatocellular carcinoma opens up the exciting possibility that some types of cancer can now be prevented by vaccination.

There is a trend towards some decentralization of cancer treatment – for example, the more basic chemotherapy treatments for lung and breast cancer are now available in Greenland, where residents once would have had to travel to Denmark for these procedures. There is some evidence that the management of cancer in the Arctic is less than optimal. Data from Alaska suggest that Alaska Natives tend to be diagnosed at later stages and have lower survival rates than non-Natives. However, survival rates are improving, particularly for colorectal and liver cancer.

ardiovascular diseases (CVD), or diseases of the circulatory system (heart and blood vessels), are the leading causes of death in most developed countries. From a public health perspective, two types of CVD are particularly important: ischemic heart disease (IHD) – the narrowing of the coronary arteries leading to angina and myocardial infarction (“heart attacks”); and cerebrovas-

cular disease (CBD) or stroke, involving the blood supply to the brain. Rheumatic heart disease, the result of rheumatic fever caused by type A streptococcal bacteria, has been on the decline since the midtwentieth century due to advances in antibiotic therapy. Trends in IHD and CBD are indicative of lifestyle changes, such as diet and physical activity, in the population.
Circumpolar Mortality Patterns Fig. 15.1 compares CVD mortality rates in circumpolar regions. Across Russia, CVD mortality rates are much higher than in the other regions. Breakdowns of CVD into IHD, CBD, and others are available for non-Russian regions (Fig. 15.2), among which Finland and its northern regions have much higher rates of
105 IHD, whereas Greenland has the highest rate of CBD. Within Scandinavia, northern regions have higher rates of CVD than the national averages. In the multi-ethnic population of the Northwest Territories in Canada, the agestandardized mortality rate for both ischemic heart disease and stroke are higher than the national rates, whereas for the predominantly Inuit population of Nunavut, only stroke mortality is higher. Among Alaska Natives, mortality from ischemic heart diseases increased during the 1980s and then began to decline during the mid1990s. At the same time, national American rates have declined dramatically. The Alaska Native rate is still lower than that of the state as a whole as well as the U.S. all-races rate. For stroke, the mortality rate has consistently been higher among Alaska Natives.
Fig. 15.3 – Electrocardiography during home visit [K. Young]
Fig. 15.4 – Carotid ultrasonography as part of a health survey [P. Bjerregaard]
It is a long-held belief that IHD has been rare among the Inuit due to the protective effects of their traditional diet, which has a high content of polyunsaturated fatty acids of marine origin. However, poor mortality statistics and the lack of incidence data make it difficult to confirm this assertion. Indeed, judging by medical history and the presence of electrocardiographic evidence of past IHD among survivors (Fig. 15.3), data from Greenland and Alaska indicate that their IHD rates are comparable to those of Americans and in the middle range of rates in European populations. As myocardial infarctions and strokes are end points in a long process of atherosclerosis (hardening of the arteries), a promising approach to assessing risk of CVD is by ultrasound studies of the patency of the carotid arteries, a non-invasive procedure (Fig. 15.4).

Some data on the mortality and incidence of CVD among Sami are available. In Sweden, the mortality rate for all CVD is significantly higher among Sami than non-Sami women, but there is no increased risk among Sami men. In Norway and Finland, however, a lower risk for cardiovascular diseases has been observed among Sami.
AMI = acute myocardial infarction
More refined diagnoses are available – separately for reindeer-herding and non-herding Sami in Sweden – from the Sami population and health database created by Hassler and colleagues (Fig. 15.5). A reduced risk of developing and dying from IHD among Sami women relative to non-Sami women is observed only among herders. Male Sami herd-

ers, on the other hand, experience a lower risk of stroke than non-Sami. Among Sami, the risk of subarachnoid haemorrhage, a subtype of stroke due to bleeding rather than blocked vessels, is substantially higher than for non-Sami. The difference is especially great for herders.
Cardiovascular Risk Factors The pattern of cardiovascular risk factors in many indigenous populations has changed since the 1950s. The prevalence of type 2 diabetes and obesity has increased, whereas physical activity has declined. Dietary practices have shifted towards a more Western tradition, although the consumption of marine mammals and fish is still high compared with North American and European countries. These risk factors are discussed in more detail in their own chapters. Hypertension is an important risk factor for

cardiovascular diseases (Fig. 15.6). Analysis of merged datasets of four surveys among Inuit in Canada, Alaska, and Greenland conducted during the 1990s showed that mean systolic blood pressure among the Inuit ranked as intermediate on a global scale, and lower than most European populations. The prevalence of hypertension tends to increase in older age groups. In Arctic Russia, there is substantial variation in mean blood pressure levels among various indigenous groups (Fig. 15.7). Since at least the 1930s there has been considerable interest in lipid metabolism among the Inuit. Surveys in northern Canada, Alaska, and Greenland have generally demonstrated a favourable lipid profile of generally low levels of triglycerides (TG), total cholesterol (TC), and low-density lipoprotein-cholesterol (LDL), and high levels of high-density lipoprotein cholesterol (HDL). As more subfractions of plasma lipids were discovered, they too were
tested on the Inuit, who continue to show higher levels of protective factors such as apolipoprotein A-I and lower or similar levels of apolipoprotein B and lipoprotein (a), factors associated with a higher risk of ischemic heart disease. Studies from Nunavik and Greenland show a direct association between a marine diet, estimated by n-3 fatty acids in plasma or reported consumption of seal, and a favourable lipid profile. As expected, westernization is associated with a shift to a more unfavourable lipid profile, but this is observed only within Greenland. When Inuit have migrated to Denmark, their lipid profile has improved. This could be the result of complex dietary changes, belying the simplistic view that “westernization” is always associated with poor health outcomes. Inuit who have migrated to Denmark likely consume more fruits, vegetables, and plant oils.

16. Diabetes and Obesity
S
ubstantial lifestyle changes have occurred in circumpolar regions since the 1950s. Among indigenous peoples, declining participation in hunting and fishing is associated with a decrease in physical activity and change from a traditional diet to a more Western diet. The interaction of environmental and behavioural factors with genetic susceptibility has resulted in an increase in the burden of obesity and diabetes.
Obesity is the excess of body fat or adipose tissue. While body fat serves a variety of essential metabolic functions, its excess predisposes to significant health problems, including diabetes, coronary heart disease, hypertension, and certain cancers. In population surveys, excess body fat can only be indirectly measured. Body mass index (BMI) is a simple index of weight-for-height (= weight in kg/ [height in metres]2). According to criteria adopted by the World Health Organization, “overweight” is defined as a BMI of 25.0 to 29.9 and “obese” a BMI of 30 and above. However, the distribution of fat, especially excess abdominal fat, is a more important risk factor, which can be assessed by the waist circumference.
Prevalence of Obesity and Overweight In a pooled dataset from four studies conducted among Inuit in Alaska, Canada, and Green-
land in the 1990s, it was found that 37 per cent of men were overweight and 16 per cent were obese, while 33 per cent of Inuit women were overweight and 16 per cent were obese. The age-standardized prevalence of obesity among the Inuit ranked at the top among the highly developed countries of Europe and North America (Fig. 16.1). Among Inuit women, the mean waist circumference was higher than all reported populations globally, whereas the mean waist circumference of Inuit men ranked quite low. A study of body composition among Inuit in Alaska confirms that their visceral fat content is high, and that measurements of abdominal fat are similar among men and women Secular trend data suggest that mean BMI has increased since the 1970s among both Inuit men and women. Based on waist circumference and skinfolds, total body fat and central fat have increased, whereas lean body mass has decreased. In Finnmark in Norway, Sami men had a mean BMI that was comparable to other ethnic groups, whereas Sami women were more obese but did not suffer more from diabetes, perhaps related to their higher level of physical activity. Among Swedish Sami the mean BMI was not significantly different from non-Sami when matched by age, sex, and area of residence. Obesity is an emerging health problem among children in the Arctic. In a survey of Dene children in 5 communities in the Yukon and

The Inuit Health Survey of Children in Nunavut in 2007–8 showed a prevalence of 51 per cent of children aged three to five with a BMI exceeding the 95th percentile, and an additional 27 per cent with a BMI between the 85th and 95th percentile.

In the Northwest Territories (which included Nunavut) during the 1990s, the rate of health centre visits, used as a measure of morbidity, was found to correlate with most housing and SES indicators (Fig. 21.5).

Some socio-economic data on circumpolar regions and populations are presented in chapter 9. The association of SES indicators with selfreported health status has been demonstrated in many surveys. Those who report excellent or very good health tend to have a higher level of education and higher income.

Socio-economic Status The association between socio-economic factors and health has been observed for a long time. A gradient across different socio-economic classes, no matter how such classes are defined, has been consistently demonstrated for various measures of mortality and morbidity, for individual diseases, and for all causes combined. This gradient exists in many countries around the world and has persisted de-
Studies from the Arctic support the observation from around the world that the burden of infectious diseases is strongly associated with SES. Improved housing and reduced crowding lead to a lessening in the transmission of airborne infections. Improved sanitation and water supply plays a role in the decline of gastrointestinal illnesses, hepatitis A, and skin infections. Periods of starvation that used to weaken a population’s resistance to infections and their complications have disappeared altogether in the Arctic. Chronic diseases and their risk factors also vary according to education levels and other measures of SES, although the association has been shown in different directions according to gender. The different gender roles in a rapidly modernizing population are most likely responsible for this phenomenon.
At the population level, social change or transition is a powerful health determinant. Since the 1950s, circumpolar regions and peoples have been transformed into a modern society, thoroughly integrated in the global political and economic systems. This change is concurrent with observable secular trends in dietary patterns and levels of physical activity, the incidence and mortality rates of infectious diseases, chronic diseases, and injuries, and overall measures of mental and psychosocial health.
Inequalities and Discrimination Studies have shown a significant impact of income inequalities on health, irrespective of the absolute income level. In many circumpolar regions the distribution of income is becoming increasingly unequal (Fig. 21.6), but there are no studies that relate this to health. The Human Development Index (HDI), first introduced in chapter 10, pertains to a region or country as a whole. It is possible to adjust HDI statistically for inequality within a country, in which case a different picture emerges (Fig. 21.7). Countries such as the United States and Russia ‘lose’ more than 10 per cent of their HDI values when inequality has been taken into account, whereas the more egalitarian Nordic countries tend to lose less while moving up in their global ranking. Discrimination is another example of a social factor that likely has a negative impact on health. The influx of non-indigenous peoples into northern communities occurs at different times and with different intensities. The newcomers tend to be skilled or professional

Power imbalances superimposed on differences in socio-economic position serve to maintain social distance between the two ‘classes.’ Discrimination and lack of respect likely play a role in the myriad social problems experienced by indigenous people in many communities.
substantially better than indigenous peoples in Alaska, northern Canada, Greenland, and Arctic Russia, which reflects their comparable socio-economic position relative to the nonindigenous population in the same regions. In fact, in Alaska and northern Canada, the nonindigenous populations have a health status that is very similar to the total population of the country.
Health inequalities and disparities are also apparent at the level of regions. The northern regions in Fennoscandia generally fare better in a variety of health indicators than the northern regions of North America and Russia. Within each country in Fennoscandia, the ‘northsouth’ disparity is also much less marked, or absent altogether. The health of the Sami is
Work and Health The psychological as well as the physical work environment exert a major influence on health. Classical work exposures like chemical substances, dust, cold, noise, and repeated movements are all present in communities in the North, along with lack of job control and

high job demands, but few studies have been conducted on their relationship with health. A major work-related health factor, especially in the indigenous populations, is unemployment and under-employment. There are few jobs available, especially for unskilled workers. Indigenous women across the Arctic tend to be more successful than men in their adjustment to the rapid societal changes. While many women are able to both continue their traditional roles as caregivers in the family and also enter the labour market, the transition from hunter and sole breadwinner to wage-earner in a subordinate position – or even unemployed – has been hard for many indigenous men.

A uniquely northern occupational health issue is the hazard of reindeer herding, which is associated with a range of health problems from musculoskeletal symptoms to fatal injuries, making it one of the most hazardous occupations in Sweden. The industry is also increasingly mechanized, with the associated increased risk in vehicular accidents and decreased level of physical activity – both with negative impact on health. Mining, oil, and gas resources are rapidly being developed across the North, which will bring with it both occupational and social health consequences.

Cultural Influences While many indigenous people are economically less well-off than their fellow citizens – a fact which accounts partially for the disparity in their health status – they are also ‘protected’ in some sense by the resilience of their culture. Culture affects health in many different ways. Among traditional cultures, there are many examples of how cultural beliefs and practices expose people to, or protect them from, diseases and injuries, including dietary customs, childcare practices, religious rituals, migration patterns, kinship relations, and medical therapies. In populations undergoing cultural change, health becomes affected when there
is a discrepancy between modern and traditional values. Conflicts at the cultural level can reinforce individual vulnerability and provoke disease among those already susceptible. When groups of people belonging to different cultures come into contact, one or both groups may undergo cultural change, a process often referred to as acculturation. This is particularly acute in the case of traditional cultures coming into contact with modern cosmopolitan culture. In response to the stresses of acculturation, individuals and groups may develop coping strategies by building on their cultural repertoire. However, these stresses may be so strong and novel that the protection of traditional culture can be overturned. The degree to which cultural identity has been retained by an individual or group during the process of cultural change can be measured in terms of variables such as proficiency in the indigenous language, participation in traditional cultural activities, and the consumption of country foods. Some data are available from SLiCA (Figs. 21.8 and 21.9), and these show that the Inuit generally have a high participation rate in traditional activities, particularly subsistence hunting and fishing, and have been able to sustain their own languages. A survey of Yupik residents in the Yukon-Kuskokwim delta of Alaska found that those who identified more with a traditional Yupik way of life experienced less psychosocial stress, were happier, and were less likely to use drugs and alcohol to cope with stress. They also tended to rely on religion and spirituality to cope with stress.

Healthy Communities
Fig. 21.10 – Community activities promote social health
Individuals live in communities, and attributes of these communities are also important determinants of health. A healthy community can be characterized as a safe environment that provides opportunities for social integration. Community members’ involvement in social life (Fig. 21.10) and their shared pursuit of broader social goals can positively affect health. Research specific to the Arctic that utilizes such concepts and methods is only just beginning. A network is the web of social relationships which surround an individual. Members of a network provide emotional, financial, and other kinds of support to one another. Church membership is one type of social network, especially in small communities where they have historically come to dominate social life. The relationship between social networks and chronic diseases, especially ischemic heart disease, is well established. Data specific to circumpolar populations, however, are not available. It remains to be seen if the concept of a social network, based on work done with Europeans and Americans, can indeed be applied to Arctic indigenous peoples.

T
he health of populations depends on the integrity of the natural environment, which is strongly affected by different types of human activities. The Arctic is often erroneously assumed to be a pristine, unpolluted area. There are two major kinds of threats to environmental quality, which can be labelled ‘old’ and ‘new.’ The old kind relates to defective water supply, sanitation, and solid waste management, which affect human settlements. The associated health problems are well recognized and solutions to them already
exist. For a variety of technical, logistical, financial, and political reasons, however, they continue to be problems in circumpolar regions.
on the immediate environment. Finally, the Arctic is the sentinel of global warming, and its residents face potential new health threats that may accompany the environmental changes.
The newer kinds of threats to the environment include invisible contamination, which occurs with synthetic chemical substances that are produced far from the Arctic but transported to the region by ocean and atmospheric currents, biomagnified in the marine food chain, and bioaccumulated in humans. While there are few major industries located in the North, major mining, oil, and gas developments are underway and these may have a serious effect
Pollution of Air, Water, and Land Circumpolar regions have their share of gross, visible pollution of air and water (Fig. 22.1). In the Russian Arctic, large-scale industrialization and urbanization powered by coal has resulted in substantial air pollution. The transportation of crude oil, whether by pipeline or tanker, is subject to leakage, sometimes with
137 spectacular and devastating results – such as the 1989 Exxon Valdez catastrophe in Prince William Sound, Alaska. A legacy of the Cold War was the abandoned Distant Early Warning radar stations in Canada and the nuclear waste disposal sites in Russia (Fig. 22.2). Solid waste disposal is a major problem across circumpolar regions, from household garbage to huge, abandoned fuel tanks that litter the landscape (Fig. 22.3). The cold climate inhibits biodegradation, and whatever is flown in has to be flown out, at prohibitive costs. As the population increases, the scope of the problem increases in tandem. While there is abundant fresh water in the Arctic, contained in its rivers, lakes, and ice fields, water is not readily available in sufficient quantity and quality for the Arctic’s inhabitants. Many communities obtain untreated water from a lake or reservoir situated at high elevation, delivered by gravity to homes via pipes. In larger towns, the utilidor system of above-ground pipes delivers water from municipal treatment plants. In other communities, tanker trucks are used to deliver water to storage tanks within buildings. In smaller, more remote communities, residents use the age-old individual haul method to get water from surface or public sources. It has been estimated that Canadian Inuit consume less than the minimum Canadian national standard of 65 litres per person per day, far less than the 300 litres per day consumed by the average Canadian. Poor community infrastructure in terms of water supply and sanitation is an important factor in the occurrence of waterborne diseases such
as gastroenteritis and dysentery. Air pollution is strongly related to respiratory illnesses, including the exacerbation of chronic diseases such as asthma.

Three groups of persistent toxic substances can be distinguished based on their origins, functions, and chemical structures. Those that are organic compounds are also referred to as persistent organic pollutants (POPs): » industrial compounds and by-products (each group or family may itself be comprised of up to several hundred ‘congeners,’ or chemically related compounds): PCBs (polychlorinated biphenyls), with 209 congeners; PCDDs (polychlorinated dibenzop-dioxins) or dioxins, with 75 congeners; PCDFs (polychlorinated dibenzofurans) or furans, with 135 congeners; PCNs (polychlorinated naphthalenes), with 75 congeners; PBDEs (polybrominated diphenyl ethers); PBBs (polybrominated biphenyls); PAHs (polycyclic aromatic hydrocarbons); PFAS group (perfluorinated alkylated substances); and HBCD (hexabromocyclododecane).

Fig. 22.2 – Nuclear activities in the Arctic, 1950–2000 Numerous nuclear explosions have taken place in the Arctic. One of the largest military nuclear testing facilities is on Novaya Zemlya, Russia. Between 1955 and 1990 the Soviet Union detonated eighty-eight atmospheric, twenty-nine underground, and three underwater nuclear devices. Dozens of civilian nuclear explosions have also occurred in the Russian Arctic where nuclear bombs were used into the late 1980s for seismic studies, for mining, and in attempts to extinguish oil-field fires. In 1968 a U.S. Air Force B-52 bomber carrying four nuclear bombs crashed and exploded near the Thule Air Base in Greenland, although there was no thermonuclear reaction. Hundreds of poorly protected civilians and military personnel were involved in the clean-up. The lone accident in the Canadian Arctic occurred in 1978 when the Soviet satellite Cosmos 954, which had an onboard nuclear reactor, failed to separate from its booster and broke up on re-entry, spreading radioactive fuel and debris over the Northwest Territories. The worst accident of all time, Chernobyl in 1986, did not occur in the Arctic (it was in the Ukraine, just visible in the bottom right of the map), but did result in extensive contamination of Arctic vegetation grazed on by Sami reindeer herds.

Many of these contaminants are transported to the Arctic by air, ocean or river water, and ice drift. Most of them are lipid soluble and are stored in the fat of marine mammals. Their concentration increases with each step in the food chain and is very high in predatory species like seals, toothed whales, and polar bears (Fig. 22.4). Generally, it is the coastal human populations who have the highest concentrations of many of these contaminants, especially those who obtain a substantial proportion of their diet from marine mammals. The growing fetus and the newborn child are especially sensitive to the toxic effects of environmental contaminants. These substances may exert their toxicity for decades because of their resistance to degradation. Several of these substances move from mother to fetus via the umbilical cord and from mother to child via breast milk. The levels of these contaminants in maternal blood during pregnancy give an indication of the potential risk to the developing fetus. Of special concern are the long-term, subtle effects of the contaminants that might influence reproductive health, affect pregnancy outcomes, reduce immunity, delay mental development, and increase the risk of cancer. Since 1991, the Arctic Monitoring and Assessment Programme (AMAP), a multidiscipli-
nary, international expert group reporting to the Arctic Council, has been monitoring levels of contaminants in Arctic populations and investigating their impact on human health. There are substantial regional differences within the Arctic in terms of human exposure and biological effects (Fig. 22.5 and Fig. 22.6). Regionally high concentrations of PCBs and DDT-group contaminants, but more moderate levels of mercury, point to possible local sources of contaminants in the Russian Arctic with long-range transport playing a relatively minor role. In northern Canada and Greenland, on the other hand, long-range transport is the most important source of contamination.
Risk Management Actions can be implemented at many levels to prevent or reduce the impact of contaminants on human health. Where there are local contamination problems, such as the PCB waste left behind in old military installations across the Arctic, these must be cleaned up. Arctic communities can do little to mitigate the longrange transport of contaminants from faraway sources. Behavioural changes on the part of residents are needed to reduce exposure. In the Faroe Islands, public health authorities have since 2008 advised against the consumption of pilot whales due to the high levels of mercury and PCB detected within them (Fig. 22.7). Other jurisdictions have similarly advised residents to reduce their intake of certain types of food (Figs. 22.8 and 22.9). In communicating the health risks of contaminants to the general public, health officials and

A Warming Arctic The Arctic is particularly vulnerable to climate change. Some of the effects of global warming are discussed in chapter 3. Potential health impacts may be direct – such as those due to the immediate effects of heat, cold, or ultraviolet radiation; and indirect – where climate change influences intermediate factors such as settlement structure, the availability of game, and so on.

scientists must balance these risks with the nutritional benefits of country foods, especially in indigenous communities which obtain a high proportion of their diet from fish and marine mammals. The detection of alarming levels of contaminants in breast milk has led to the ill-informed advice that mothers should substitute with formula, which does not take into consideration the nutritional, psychological, and economic benefits of breastfeeding. Risk management and communication go beyond the scientific process of risk assessment and involve complex policy decisions and actions that must also take into account political, social, and cultural conditions operating in the affected population.
Examples of climate change’s indirect effects include the increasing risk of infectious diseases, especially those with insect vectors and animal or aquatic reservoirs, such as zoonotic diseases. Unique to the Arctic are permafrostdependent village sites, airfield runways, and sanitation infrastructures. Melting permafrost in these locations can destroy health facilities and homes. Arctic wildlife, including animal species dependent on sea ice, form a significant part of some regional diets and are often a critical part of traditional culture. The retreat of shore-bound sea ice makes hunting dangerous or sometimes impossible, and some species’ survival may be threatened. Local knowledge, such as when a frozen river is safe to cross, may provide poor guidance, as rapid Arctic warming makes delayed freezing and thinner ice a major cause of drowning in the winter. Worldwide climate warming has the potential to increase the transport of contaminants into and, in some cases, out of the Arctic. General warming and the disappearance of ice may also open new areas for hunting and fishing and introduce new species to these areas. Alaska Natives have noted that Pacific salmon are spawning in growing numbers farther
north along the Bering and Beaufort Seas, and they are now able to harvest this previously unavailable species. Moose have also continued to extend their range northwards in Alaska. Beavers have moved farther north in Alaska, damming streams. Many more migratory waterfowl are being harvested by Alaska Natives in the interior. In Greenland, traditional subsistence based on the hunting of seals and whales began to make way for a modern cash economy based on the fishing industry. As a result, the population began to be concentrated in fewer and larger towns and the number of villages decreased. In the 1960s, however, a cooling climate along with overfishing resulted in the disappearance of the cod from the west coast of Greenland. At the same time, however, large numbers of shrimp were detected in Disko Bay. The shift from cod fishing to shrimp fishing further changed Greenlandic society. Lively towns grew around the shrimp factories. This continued until the 1990s when overfishing and warming waters again began leading to dwindling stocks in southern Greenland. Many factories closed, followed by the loss of jobs and population. Given this confluence of factors, it is important to recognize that climate change is only one of the many issues affecting health and social change in the Arctic. Population movements from small villages to larger towns are as much the result of conscious political forces encouraging the population to move to towns with schools, health care, shops, and so on as they are the result of changes in the physical environment.

An Arctic Response What should be the response of northern society and its health system to climate change? A priority that has often been cited is a surveillance system to monitor both environmental changes and health effects. Such a system can incorporate community-based observation, which in indigenous communities should also draw upon traditional knowledge and the vast experience of long-term residents attuned to the nuances of the land. Responses to extreme climatic events need to be planned in advance and implemented through government-community partnerships. Adaptation options need to be considered, for example, in facilities design, training, and service delivery. Arctic communities cannot wait for the rest of the world to agree on lofty targets, develop new technologies, and implement incentives or penalties for industrial redesign and individual behavioural changes. Indeed, some circumpolar regional governments are looking ahead at strategies that will ‘take advantage’ of climate change (Fig. 22.10). The Greenland
government, for example, aims to develop agriculture, sheep ranching, and dairy farming. Meanwhile, Canada has begun laying the groundwork for elaborating community-led strategies to meet the effects of climate change on the health of individuals and communities (Fig. 22.11).
An Enduring Resilience Northern peoples are resilient and adaptable, and are not helpless victims. Climate change in historical times has been the driver of cultural change in the Arctic. Global warming ushered in the Neolithic Era (Late Stone Age) in Eurasia 7,000 years ago. The development of marine-based subsistence promoted the colonization of the Arctic from Norway to the Bering Sea. The Thule culture, the direct forebears of today’s Inuit, sprang up from the Bering Sea coast 1,000 years ago, developed innovations such as hunting large sea mammals in open water using skin boats, and took advantage of the climate change that enabled them to migrate across the Arctic from Alaska to Greenland.

differ according to local resources (Figs. 23.3). In Greenland, the eastern Canadian Arctic, and along the Arctic coastline, marine mammals – seal in particular – are the traditional staple. For some inland groups, caribou make up the greatest part of the traditional diet. In all regions the staple is supplemented with a variety of other mammals, fish, birds, and plant food such as berries and seaweed, although plant food makes up a very small proportion of the overall diet in much of the Arctic (Fig. 23.4).

s noted in chapters 15 and 16, cardiovascular and metabolic disorders are becoming more prevalent in circumpolar populations. Among the main causes of such developments are changes in the diet and levels of habitual physical activity, part of the complex process of social transition to a globalized economy and its modern lifestyles.
Subsistence and living off the land, besides the immediate nutritional benefits, promotes physical activity and enhances spiritual health.
Diet and Nutrition
The availability of game varies according to season (Fig. 23.2). Men usually consume country food more frequently than women, and young people consume considerably less country food than older people. The species consumed
For the indigenous people of the Arctic, food obtained from hunting and fishing, or ‘country food,’ continues to be a major part of their diet.
There is variation across the Arctic in the patterns of consumption. SLiCA results show that for about two-thirds of the surveyed households, locally harvested meat and fish make up at least half of the total meat and fish consumed. The proportion is highest in Alaska and lowest in Chukotka (Fig. 23.1).
Dietary surveys have shown a sustained, yet decreasing, level of consumption of locally harvested food. The high cost of imported foods (Fig. 23.5) and inadequate incomes mean that the nutritional value of country foods cannot easily be substituted and compensated in full. Country foods are also becoming expensive, in terms of capital expenditures on guns, boats, and snowmobiles, and the recurrent costs of fuel and ammunition. Analyses������������������������������������ of traditional food consumed by indigenous people show that the density of most nutrients is superior to that of imported food. Calcium and vitamin A are two nutrients that tend to occur in concentrations below the desired level. Imported food is generally rich in saturated fatty acids while the fat of marine mammals and fish are high in polyunsaturated fats. Traditional food does not contain refined sugar and is therefore beneficial for dental health. Some health authorities in circumpolar

145 regions have designed food guides that incorporate traditional country food (Fig. 23.6). The notion that country food is healthy and imported food is unhealthy, however, is an oversimplification. The ‘dietary package’ of country food now also contains contaminants such as mercury (see chapter 22). Imported food also has healthy and unhealthy aspects. While it is true that many Arctic residents favour junk food and sugared beverages, and consume lard and fatty meats instead of vegetables, fruit, and pulses, to be unhealthy is not an inherent property of imported food but rather a result of dietary habits that can be changed.
Food Security A disturbing but increasingly common phenomenon in affluent, developed nations such as the circumpolar countries is the appearance of food banks and breakfast clubs to cater to families and children without basic access to food, let alone a healthy diet. According to the United Nations Food and Agriculture Organization, food security exists when all people, at all times, have access to sufficient, safe, and nutritious food to meet their dietary needs and food preferences for an active and healthy life. A Canadian survey asked specific questions about whether, due to a lack of money, members of the surveyed household in the past year (a) did not eat the quality or variety of foods they wanted; (b) worried that there would not be enough to eat; and/or (c) did not have enough to eat. Those who responded ‘often’ or ‘sometimes’ to at least one of these questions were considered to have experienced food insecurity. As expected, food insecurity
is income dependent. However, regional disparities are pronounced, even when stratified by income (Fig. 23.7). Nationally, food insecurity affects the young more than the old and indigenous people more than others. In the North, barriers to food security and the consumption of traditional food may be overcome by increased economic support for local community hunts, the installation of communal freezers, and better access to cheaper and higher quality market foods. These measures could potentially address both food insecurity and the improvement of nutritional status. Urban horticulture is common in Arctic Russian towns, although in only a few larger urban centres elsewhere. It is usually undertaken in small plots and greenhouses. This can provide a supplemental food source (Fig. 23.8).
Physical Activity The traditional circumpolar lifestyle of hunting and fishing, dogsledding, hauling water by hand, and carrying young children on one’s back is physically demanding. Among the Sami, reindeer herding is a very labour-intensive occupation, often carried out in hostile environmental conditions. Since the 1950s, modernization has progressed across the Arctic, resulting in major shifts in subsistence patterns and their associated lifestyles. Many traditional activities continue to be practised, but more as recreational activities in one’s leisure time. Families may engage in hunting, fishing, berry picking, camping, and boating, and the concept of ‘exercise’ has made inroads in the North. Depending on community facilities, typical sports include skiing,

soccer, jogging, bicycling, softball, aerobics, and so on. The degree to which physical activity is involved in work and leisure varies from region to region. Within Greenland there is a trend towards higher physical activity levels in connection with westernization, and Inuit who migrate to Denmark are physically more active than those who stay behind in Greenland. Such observations need to be interpreted with caution because of the very different cultural context of physical activity in the North. In northern Norway, despite being less physically active in their leisure time, Sami men and women are more active at work and have a higher total physical activity score than nonSami. In northern Canada, the prevalence of leisuretime inactivity is highest in Nunavut (almost 60 per cent), compared to less than half in the
(c) The rapidly expanding Yellowknife Community Garden collective [R. Rawat]
Northwest Territories and Yukon, which is close to the Canadian national average. Women in general tend to be less active than men. Data on physical activity among Alaskans are available from the Behavioural Risk Factor Surveillance System (BRFSS). Fig. 23.9 shows the prevalence of physical inactivity, defined as someone who has not engaged in any leisuretime physical activity in the past month, other than what is required for their regular job. Inactivity is more prevalent with increasing age, decreasing education and income, and among Native populations. In most studies of physical activity in the circumpolar regions, measurement of physical activity is based on questionnaires regarding leisure-time physical activity which have been adopted from studies of non-indigenous populations. The focus on leisure-time physical activity, rather than total activity, may be less useful in these populations where leisure time
and occupation time are not necessarily clearly separated and organized sports are not always available. Many tools for the measurement of physical activity may not necessarily assess culturally based forms of physical activity and may underestimate the activity level of domestic care. Women tend to engage in lowerintensity activities, like walking, childcare, and housework – all of which are relatively more difficult to assess and less reproducible than higher-intensity activities such as many organized sports. This reinforces the need to validate existing measurement tools or develop new tools to use in these populations.
Policies and Strategies Circumpolar countries and regions have produced action plans, strategies, and policies to promote healthy lifestyles. A few of these are mentioned here.
147 Twelve ministries in Norway were involved in the design and implementation of an action plan on nutrition called Recipe for a Healthy Diet for 2007–11. The plan included seventy-three recommendations grouped under five strategies: (1) availability of healthy food products; (2) consumer knowledge; (3) qualifications of key personnel; (4) local partnerships; and (5) a focus on nutrition in health care services. Examples of specific actions include healthy meals in kindergartens and daycares, vitamin D supplementation for immigrant infants, food marketing directed at children, and nutritional training in the workplace and health care system. This nutrition action plan followed on the heels of an earlier action plan on physical activity for 2005–09. In Sweden, a review of health promotion activities at the municipal level indicated that just 26 out of 290 municipalities had an action plan for physical activity while only 13 had one for healthy diets. Finland has a particularly strong tradition in partnerships with non-governmental organizations, such as the Diabetes Association and the Heart Association, in developing disease-specific strategies and programs in health promotion. The Greenland prevention program Inuuneritta focuses on, among other things, the intervention against a poor diet and a sedentary lifestyle. In addition to usual public education activities, much emphasis is put on training courses for health care workers and other staff on these topics and also on funding school programs. Municipalities can apply for subsidies for school meal programs. Alaska’s Nutrition and Physical Activity Plan
grew out of the Alaska Obesity Summit in 2003. The first and foremost of its overarching goals is to increase awareness, followed by behavioural change strategies to improve physical activity levels, encourage healthy food choices, and attain healthy weights. It develops separate targets for programs based in schools, healthcare settings, communities, and mass communication.
Food Economics and Political Change The political turmoil in the former Soviet Union has had considerable impact on the diet of its northern indigenous populations. At the national level, the withdrawal from state monopoly in foreign trade and the growing share of imported foods in the 1990s introduced new foodstuffs for the consumer markets. Such changes made their way even to remote villages in the tundra. However, the dismantling of the Soviet system of distributing social benefits has resulted in considerable economic hardships among remote northerners. Food production and distribution was affected, with the closing of livestock and poultry farms and inland fisheries, and a reduction in centralized, inter-regional food delivery. In coastal Chukotka, collectivized whaling involving large vessels ceased, reducing the supply of whale meat (primarily for fur farms but also that consumed by the indigenous people). Overall, in response to the post-Soviet economic crisis, northern indigenous peoples have shifted their diet to the cheaper market foods that they can afford, but also have increased their use of locally obtained food
