The International Tundra Experiment is a network of researchers examining the impacts of climate change on tundra vegetation throughout the Arctic, Antarctic and Alpine regions of the world. The goals of the networks are to document, understand and forecast changes in the tundra biome. Most members of the network do research at sites established in the early 1990s using standardized measurement protocols and a common warming experiment. The power of the network allows researchers to pool their data and make statements about the fate of the tundra biome as a whole. The four main areas of activity as part of the International Polar Year are: 1 vegetation change; 2 changes in the timing of key biological events (phenology); 3 changes in nutrient cycling; and 4 changes in carbon balance. Each of these areas is described below with a photograph and caption.

The goal of ELOKA is to facilitate the collection, preservation, exchange, and use of local observations and knowledge of the Arctic by providing data management and user support, and to foster collaboration between local and international researchers. Over the last decade, Arctic residents and indigenous peoples have been increasingly involved in, and taking control of, research. Through Local and Traditional Knowledge (LTK) research and community-based monitoring, Arctic communities have made, and continue to make, significant contributions to understanding recent environmental change.

The food-borne parasites Trichinella nativa, Toxoplasma gondii, and Anisakis simplex are significant Arctic human zoonoses; endemic to some regions and directly related to the consumption of country foods. Many Northerners remain reliant on wildlife as a source of food, financial income and cultural identity and are demanding programs which will provide greater security in the safety of country foods and programs that ensure the long-term sustainability of wildlife populations. Changing climatic conditions are predicted to alter wildlife habitat, facilitate the northward migration of wildlife diseases and parasites, and alter contaminant cycling and fate; all of which have the potential to detrimentally affect the health and long term sustainability of wildlife populations and ultimately the source and safety of country foods (ACIA 2004; Boonstra 2004; Derocher et al. 2003; Harvell et al., 2002; Hoberg et al., 2002; Kutz et al. 2004; Lie et al. 2004 & 2005). Adequate baseline data (benchmarks) regarding the current health conditions of wildlife (including zoonotic pathogens) is therefore urgently needed for the assessment and prediction of wildlife health impacts resulting from the cumulative impacts of multiple stressors associated with climate change and exposure to anthropogenic contaminants.

This programme is framed by Arctic peoples’ resiliency, where partnerships are fostered which highlights the strength and aspiration of Arctic residents.

The network for present and future circumpolar freshwater lake research and data management (NORLAKES 4 Future) is a multidisciplinary and –national network under the International Polar Year initiative that seek to connect activities and data of complementary research groups that are or will perform limnological research in the Arctic.

SIKU is one of several IPY 2007–2008 projects aimed at documenting indigenous observations of environmental changes in the polar areas, with its specific focus on sea ice and the use of ice-covered habitats by the residents of the Arctic. Incidentally, the project’s acronym SIKU is also the most common word for sea ice (siku) in all Eskimo/Inuit languages, from Chukotka to Alaska, Canada, and Greenland. As a collaborative international initiative, SIKU brings anthropologists, human geographers, sea ice and climate scientists, marine and ecosystem biologists from the U.S., Canada, Russia, Greenland, and France in partnership with almost two dozen indigenous communities in Alaska, Arctic Canada, the Russian Chukchi Peninsula, and Greenland. SIKU, like many IPY 2007–2008 projects, is organized as a consortium of local or national initiatives with their respective budgets provided by the national funding agencies. Presently, the main operational components of the SIKU initiative are the Inuit Sea Ice Use and Occupancy Project (ISIUOP) in Canada (see summary report on the ISIUOP activities), the Alaska-Chukotkan portion of SIKU made of several local efforts (see field reports by Nicole Stuckenberger and Josh Wisniewski), and the Greenlandic component that is being developed as a part of the continuing SILA-Inuk project administered by the Inuit Circumpolar Conference (ICC)-Greenland office in Nuuk. Recently, a small French team secured its funding to join the SIKU initiative and to conduct sea ice knowledge studies in Greenland.

There are over 4 million wild and 1.8 million domestic reindeer and caribou inhabiting the earth’s arctic regions. This keystone species has been an economic and cultural mainstay of nearly every indigenous group in the Arctic. Recent profound changes have been occurring in the North with the potential to jeopardize the relationship forged over countless generations between Rangifer, the land and the people. The CARMA Network network defines its mission:

To monitor and assess the impacts of global change on the human/Rangifer system across the Arctic through cooperation, both geographically and across disciplines.

Our IPY activities are designed to further an interdisciplinary and cross-institutional discussion about climate change, Arctic peoples, and international policy through: a series of lectures and workshops; a museum exhibition and related publications; and, the organization of the 2007 Arctic Science Summit Week (ASSW).

CAVIAR - Community Adaptation and Vulnerability in the Arctic Regions – is an international research consortium consisting of partners from the eight Arctic nations. The main goal of CAVIAR is to identify how projected changes in climate interact with changes in social and natural conditions, and how such interactions shape vulnerability and adaptation to climate change in Arctic Regions. Comparable case studies across Arctic communities will provide a basis for synthesizing knowledge of vulnerabilities and for exchanging experiences with adaptation.
