For many indigenous communities that have lived in the Arctic for millennia, sea ice has been an integral part of their living environment. As a place where they have spent a significant part of their lives hunting, fishing and even dwelling on the ice, the intimate understanding of sea ice the Inuit and other indigenous communities have has allowed these communities to survive and even thrive in the Arctic for millennia.
This understanding of sea ice has been passed down from generation to generation through indigenous languages rich in highly specific terminology pertaining to sea ice and sea-ice related phenomena, as well as by firsthand experience on the ice.
However indigenous sea ice knowledge and use in Inuit and other indigenous communities in the Russian Far East and western Alaska who use sea ice has been changing in recent decades. The reasons for these changes are numerous and include not only climate change, but also numerous sociological factors that have influenced the transmission of their special knowledge from older generations to younger generations.
Yet it is important to keep in mind that the extent to which climate change and sociological factors have influenced sea ice knowledge and use differs widely from place to place. Climate change has not affected indigenous communities across the Arctic uniformly, and the influence of sociological factors varies from community to community.
It's an understatement to say that climate change has been a ubiquitous reality in the Arctic. With the average temperature across the Arctic having risen twice s fast as the rest of the planet over the last century, this has impacted the thickness and extent of sea ice, creating consequences for indigenous communities who depend on sea ice for their livelihoods. Some of the impacts of climate change on how indigenous communities use sea ice includes:
Climate change is not the only reason the sea ice habits of Arctic residents have been changing; a broad range of sociological factors have influenced how and why Inuit and otehr indigenous communities in the Russian Far East and western Alaska go onto the ice and how much indigenous knowledge residents in their communities have retained. Some of the primary sociological factors include:
In order to better understand the phenomenon and investigate the reasons behind the changes, one IPY project (n° 166), called Sea Ice Knowledge and Use (SIKU - which is also the most common word for sea ice in all Inuit languages from the Bering Strait to Greenland) is having a look at how Arctic residents are using sea ice and ice-covered habitats, how often and for what purpose, and whenever possible comparing indigenous sea ice knowledge and use of today with that of the past. Included within SIKU are a number of initiatives, including the creation of sea ice dictionaries, which is aimed at preserving the wealth of knowledge stored in the rich lexicon of the Inuit, Yupik and other indigenous languages.
By taking a "snapshot" of the current situation of indigenous knowledge in the Arctic, it will help Northern communities find ways to deal with climate change and provide a set of baseline data for any future researchers and future Arctic residents alike.
The SIKU project has been employing local residents to observe and document environmental changes in the Polar Regions in addition to collecting climate and weather data. The project provides an umbrella framework bringing together several dozen sub-projects as well as anthropologists, human geographers, sea ice specialists, climate scientists, marine and ecosystem biologists from various countries including the US, Canada, Russia, Greenland, and France in partnership with almost two dozen indigenous communities in the Russian Chukchi Peninsula and Alaska, Arctic Canada, and Greenland.
The three-year IPY research effort was launched in 2006-2007 as a collaborative effort that involved scientists from five nations (US, Canada, Russia, Greenland, and France) and indigenous experts from over 30 communities across the Arctic. A book summarizing the main outcomes of the SIKU project is in preparation and will be released by the time of the June 2010 IPY conference in Oslo, in which scientists will discuss their findings from the IPY.
