In order to support climate change adaptation in the communities of Nunavik, an innovative multi-technique approach to map permafrost conditions and assess risks of geohazards at the community-scale level was applied. Four maps were produced for each community: 1- a surficial geology map, 2- a map of permafrost conditions based on ground-ice content and depth to bedrock, 3- a map of potential for construction and 4- a geohazard risk assessment map. Local ground temperature data from thermistor cables were used to calibrate one-dimensional numerical models to estimate future permafrost temperature changes and probable rates of degradation in different environmental settings within the communities and under different climate change scenarios for the 2019-2100 period. Throughout this project, abundant consultations were held in communities and with stakeholders to better understand their concerns and to provide pragmatic recommendations for improving construction methods and land-use planning to face the challenges of permafrost thaw. Specific recommendations were made to the higher levels of government for improving construction practices. Inuit aspirations, culture and leadership remain keys in how to integrate permafrost geotechnical knowledge in planning a safe future for the communities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
