Abstract
Unfavorable hydrothermal conditions and excessive pasture loads in the European South of Russia led to dust storms in September and October 2020 and in May and June 2021. As a result, the area of desertification in the Republic of Dagestan, the Republic of Kalmykia, Astrakhan Oblast and Stavropol Krai has increased several times. The UNESCO biosphere reserve ‘Kizlyar Bay’ is located in the north of Dagestan. Economic activities, including grazing, are allowed in its cooperation zone. Overgrazing led to a 15% (about 90 km2) increase in the area of land without vegetation in 2021 as compared to 2019. It is necessary to take urgent measures aimed at regulating livestock population, controlling compliance with the grazing regime of distant-pasture cattle breeding, carrying outvegetative reclamation, and organizing a monitoring system to prevent further pasture degradation in the cooperation zone of the reserve.
