Permafrost degradation in Siberia – Socio-Economic Aspects:
As large parts of Siberia are underlain by ice-rich permafrost, global warming has a strong impact on environment and society in this region. Moreover, Arctic and sub-Arctic regions are expected to experience a particular strong impact of global warming.
The permanently frozen ground is sensitive to higher temperatures and warms up increasingly. Additionally, local human activities contribute to disturbances of the thermal state of permafrost. Consequently, permafrost starts to degrade predominantly due to melting of the enclosed ground ice.
This leads to local surface subsidence, which has also major impacts on human infrastructure. For instance, buildings, transport routes and pipelines may increasingly become instable and damaged.
Moreover, landscape changes influence traditional land use of indigenous people in rural areas (agriculture, livestock breeding, watering). At the same time one can expect further environmental problems in the future as the exploitation of large natural resources in Siberian permafrost areas will increase in the future.
