Permafrost degradation plays a very important role in the functioning of ecosystems, biogeochemical cycles, surface and subsurface hydrology and eventually affects human life in high latitudes causing infrastructure damage, reducing accessibility to subsistence resources, and contributing to climate change. This session is dedicated to studies of multiscalar dimensions of the societal, environmental and infrastructure changes associated with thawing permafrost from the level of a single community to the regional and global scale. We invite experts both in social and natural studies including environmental sciences, hydrology, biogeochemistry, geography, anthropology, to share their findings and discoveries in the research of ongoing permafrost-related transformations in the regions of Arctic and Sub-Arctic. We also solicit contributions dealing with the engineering issues and solutions aimed to offset infrastructure damage due to permafrost degradation.
