Abstract
In Canada, about 50% of the ground surface lies within the permafrost region. In the north, the integrity and the performance of infrastructure, including roads, buildings, pipelines, embankments, structures in coastal environments, commonly relies on the stability of the frozen ground. Permafrost degradation in response to development and the warmer climate predicted by climate-change models for northern latitudes may exacerbate the problems related to warming of permafrost, especially in the discontinuous permafrost zones. Climate change impacts on permafrost areas are presented and discussed in terms of infrastructure in the western Arctic, which is a national strategic area for the development of natural resources, transportation corridors, and tourism for some communities. Examples of impacts from two communities (Norman Wells and TuktoyaktuK) in the Northwest Territories are highlighted. Potential adaptation measures to mitigate consequences are also described.
