Facing the challenge of permafrost thaw in Nunavik communities: innovative integrated methodology, lessons learnt, and recommendations to stakeholders
To support climate change adaptation in the communities of Nunavik, an innovative multitechnique 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 permaf...

To support climate change adaptation in the communities of Nunavik, an innovative multitechnique 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 1D 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 essential in integrating permafrost geotechnical knowledge in planning a safe future for the communities. |
