In accordance with the National Plan for Climate Change Adaptation, special economic and social measures should reduce the vulnerability of the population, economy and nature to the consequences of climate change, as well as use the opportunities arising from such changes. The development of such measures requires a forecast of the stability of the infrastructure to changes in permafrost conditions. The "Scientific Center for the Study of the Arctic" (Salekhard) has prepared a program to implement this work. It should provide an analysis of the permafrost hazards of Yamal using available cartographic information, remote sensing data, and geological and geotechnical spatial data. Two tasks are under decision: 1) Construction of an actual permafrost map based on specialized maps. Maps are created in the branches of "geotechnics" and "geocryology" to provide a wide range of consumers with relevant, reliable, comparable and accessible information about the state of permafrost, trends and forecasts of its dynamics, as well as the geotechnical, economic and social problems associated with it. 2) Development of a local monitoring and remote sensing data collections to build an open regional GIS. The information system allows to automatically update the Yamal permafrost maps, display the results of predictive modeling for 50-100 years, and carry out the function of alerting the population in case of emergencies related to permafrost dynamics. The obtained experience is proposed to be used for the international development of the methodology for updating the circumpolar permafrost map of the Northern Hemisphere.
