Pasture Degradation

Under the conditions of a complex geomorphological structure of the territory, uneven particle-size distribution, and often thin profile of soils, degradation processes are dominated by linear and sheet erosion. Based on the intensity of development of water erosion and deflation processes and, consequently, different disturbances of the soil profile, as well as according to the results of evaluating the areal development of all types of erosion processes, three degrees of land degradation are shown on the map in shading: slight, moderate, and severe. They were determined by the share of the main categories of eroded soils as a percentage of the agricultural lands area. Twenty-four percent, up to 42%, 47%, and more than 60% of developed lands are eroded in varying degrees in the Baikal region, in the territory of the Republic of Buryatia, in the Olkhon district, and in some areas of Mongolia, respectively.

As a result of a special analysis and assessment of the pasture condition, three categories of the degree of their degradation are distinguished in the map “Pasture degradation”, namely: low, moderate, and high. The map’s explanatory note explains the diagnostic features of pasture degradation. The predominant part of pastures experiencing moderate anthropogenic impact is classified as slightly or moderately disturbed.

In general, the map is the basis for preventing the development of dangerous geo-ecological situations in the region, organizing environmental activities, and optimizing the management of the biogeochemical environment of the population’s life-sustaining activities.
