Khanty-Mansi Autonomous Area

Geographical characteristics: the region is characterized by an island distribution of permafrost. The region is less exposed to the predicted temperature increase due to its remoteness from the Arctic Ocean.

Economic risks:

- Khanty-Mansi Autonomous Area produces 50.8% of all oil in Russian Federation; there are already more than 1,900 accidents per year at oil fields due to soil deformation and permafrost degradation. More than 55 billion a year (as of 2010) are allocated to maintaining the serviceability of pipelines and eliminating their deformations.

- By 2050, the bearing capacity will be reduced by 31% and ground subsidence will be equal to 7 cm. It is expected that 96% of the financial costs will be related to the deformation of the infrastructure as a result of the ground subsidence.

- For the Khanty-Mansi Autonomous Area the greatest risk is the destruction of oil and gas infrastructure (rather than the destruction of buildings). By 2050. 27.2% of all infrastructure will be negatively affected by permafrost degradation.

Social risks: The indigenous small-numbered peoples of the North living in Khanty-Mansi Autonomous Area, make up 2% of the total population of the region and about 10% of the total number of indigenous small-numbered peoples of the North. Risks for the population are represented by oil field accidents and oil pollution of soil and water bodies, release of toxic and radioactive elements previously stored under permafrost.

Research and project interest: Practical projects to adapt the extraction infrastructure to permafrost degradation and climate change.

Conclusions: In the Khanty-Mansi Autonomous Area, the main risks and prospects of applying technologies to protect permafrost are associated with the destruction of infrastructure and the increasing frequency of accidents at oil fields, so focusing on the study and protection of permafrost corresponds to the urgent needs of the region. The social aspects of permafrost thawing are less acute in the region.
