The Potential of Sustainability, Evolution and Adaptation of Coastal Geosystems in the Conditions of Climatic and Man-Made Changes (The Example of Sakhalin)

Morpholithodynamic features and trends of coastal zone development, technogenic load, location and geospatial parameters of dangerous, vulnerable coasts of Sakhalin Island are considered, which should become the basis for increasing both socio-economic and natural sustainability of the coasts in conditions of rapid and man-made changes. The peculiarities of the response of coasts composed of easily erodible rocks and rocky shores to these changes are shown. Attention is paid to the emission of climatically active gases during the destruction of biomorpholithosystems of the coast. Quantitative data on the most representative in this respect coast of the Amur Estuary are presented.
