The report shows the consequences of dust storms at the end of September and in October 2020 in the south of the European part of Russia: the Astrakhan Region, the Stavropol Krai, the Republic of Dagestan and the Republic of Kalmykia. Due to the dry vegetation season, excessive pasture loads and locust infestation, vegetation cover was extremely degraded in the territory under study. Dust storms were provoked as a result of constant strong winds with a speed of more than 20 m/s. The storm plume reached eastern Ukraine due to the high-speed transfer of sand and dust masses. The study of the growth of sand massifs is based on classification of MODIS satellite data and on training with the use of Sentinel-2 images. Over spring period of 2020, the area of open sands in the studied territory made 171.8 thousand hectares. Due to negative conditions, by the end of September, it amounted up to 600 thousand hectares. Dust storms led to more than twofold increase in the area of open sands: as of October 14, the area of sands exceeded 1.4 million hectares. It is necessary to carry out real-time monitoring of the situation as well as regulate pasture loads. Under the current weather trends, unsustainable use of natural resources may lead to environmental disaster, similar to that of the 1980s.
