The problem of sustainable economic development is acutely manifested in the Arctic regions, which is due to the vulnerability of the Arctic infrastructure to climate change and landscape transformations. The reasons for the deformations of buildings and structures in the Russian Arctic are considered. The permafrost monitoring network is identified as the basis for the development of technical solutions for adapting the Arctic infrastructure to climate change; the problems and prospects for its development are considered. The analysis of technological solutions for controlling and ensuring the reliability of the bearing capacity of foundations by regulating the state of permafrost soils is presented, and a preliminary analysis of the economic efficiency of protective measures is carried out. Their cost is at least an order of magnitude less than the expected damage to infrastructure by the middle of the 21st century.
