the principles of organization and functioning of monitoring of ecological and geological systems at different hierarchical levels; detailed, local, regional, national and global. The data on the current state of the Unified State Environmental Monitoring System in Russia are presented. The purpose and structure of monitoring, the methodology and features of its organization in various types of economic development of territories are analyzed. Special emphasis in the course is placed on familiarization with unique examples of the organization of monitoring of uranium mining areas, as well as areas of oil and gas production on land and offshore. The methodology of drawing up a targeted integrated program for monitoring ecological and geological systems is presented. The allocation of engineering geoecology in the complex of Earth sciences corresponds to a real turn in the ecological consciousness of society, fully corresponds to the global course for a significant intensification of environmental protection and improvement of their effectiveness.

- the current state of geoecological research in the cryolithozone, the basic concepts and methodological methods of assessment, as well as permafrost characteristics and the type of man-made loads that determine the occurrence of crisis geoecological situations.

- the measure of the danger of the latter is the activation of cryogenic processes, which is assessed in accordance with their area, the rate of development and attenuation, the violation of natural landscapes, and the threat to the functioning of engineering structures.

- the methodology of the stability of cryogenic geosystems to mechanical surface disturbances, methods of expert assessments of the geoecological state of natural landscapes, basic techniques of environmental protection measures within the developed territories of the cryolithozone and lands of traditional nature use of the indigenous population are described.

- the scope of application of expert scores and the possibilities of their improvement are determined.

- the possibilities of small-scale permafrost-ecological mapping to determine the permafrost-landscape system connection, issues of climate-permafrost interaction, as well as the geography of cryogenic processes activation in the cryolithozone.
