Land cover and land use changes in the oil and gas regions of Northwestern Siberia under changing climatic conditions
Northwestern Siberia has been undergoing a range of land cover and land use changes associated with climate change, animal husbandry and development of mineral resources, particularly oil and gas. The changes caused by climate and oil/gas development Southeast of the city of Nadym were investigated...
