Arctic peoples inherently able to adapt given changes to various non-climatic factors

Outdated land management practices, a dearth of local decision-making bodies with real powers, a lack of long-term planning, along with long-standing educational and financial disempowerment and marginalization are among the hurdles the prevent Arctic communities from adapting to climate change, says a McGill-led research team. But Arctic communities inherently have the capacity to adapt to significant climate change. That鈥檚 partly because they are used to accepting a changeable and uncertain climate. What currently limits this ability, however, are a range of non-climatic factors that vary from one society to the next.

The researchers reached these surprising conclusions after reviewing a large number of scholarly works (135 articles) about climate change adaptation, resilience and vulnerability in Arctic societies around the globe.

But, despite the scale and speed of climate change in the north, the researchers believe that if policies and practices change in various ways, these communities are inherently well-equipped to adapt to many, if not all, projected changes in climate.

Adaptation to environmental stress will depend on non-environmental factors

聽鈥淎rctic populations are often identified as being highly vulnerable people, but that鈥檚 not necessarily what the research shows,鈥� says James Ford of 香蕉视频鈥檚 Geography Department and the lead author of an article on the subject that was recently published in Nature Climate Change. 鈥淧eople in these communities already tend to see the Arctic environment as being unpredictable and in a constant state of flux. They have repeatedly adapted to environmental changes in the past by being flexible in their use of resources. But their ability to exploit opportunities, such as the lengthening shipping seasons, or new harvesting opportunities, is challenged by various outside pressures and constraints.鈥�

The researchers discovered that depending on the region, the situations of northern communities varied significantly, based on the interaction between the speed of climate change and various non-climatic factors such as:

• the range and type of resources on which the community relies 鈥� so, for example, the livelihoods of the Viliui Sakha people in Siberia who depend on cattle and horse breeding are being undermined by changing weather and snow patterns as they have few alternative livelihood options 鈥� while the Inuit of the Canadian Arctic are altering the timing and location of traditional hunting practices with rapid changes in the sea ice 聽
• the type and effectiveness of local political leadership and input in larger decision-making questions 鈥� northern institutions often lack the time, mandate and funding to address climate change impacts 鈥� though emerging leaders in Canada and Alaska are proving to be an exception to this pattern;
• the mismatch between inflexible institutions that have created regulations and quotas for hunting and fishing and the speed of environmental change - so for example, in northern Canada and Alaska, communities are responding rapidly to changes in observed conditions while regulatory regimes have been slow and inflexible in changing regulations to respond to current conditions;
• adaptation is taking place at the household or community level, but this is mainly reactive and doesn鈥檛 translate to a larger scale or to longer-term planning; and
• economic, health and educational issues that make members of these communities more vulnerable in general, many linked to legacies of colonisation.

Co-management models and the importance of traditional knowledge

鈥淣ot all forms of institutions necessarily inhibit adaptation,鈥� says Ford. 鈥淚nstitutions can act as pathways for knowledge development. In northern Canada and Alaska, for instance, co-management practices integrate science, traditional knowledge and local needs into the management of wildlife stocks such as the beluga in the Beaufort Sea. There is some evidence that this kind of management can help speed up the exchange of information and reduce conflict about resource management, but this success has not been uniformly seen. In some cases the conflict between the role of science and traditional knowledge has been difficult to resolve, and there is a worry that discourse about adaptation may be used selectively by powerful stakeholders to advance particular pathways and political agendas.鈥�

The researchers believe that the Arctic is not only a bell-wether of climate change to come at lower latitudes, but can provide us with an understanding of the challenges to come in adapting to climate change. They suggest that further studies are needed to increase the understanding of why some communities have been able to successfully adapt and others have not in order to gain a better sense of the barriers and limits to adaptation.
