The brief communication presents the ongoing monitoring results of changes in open sand areas and deflated territories obtained using remote sensing technologies in the southeastern part of European Russia in 2023. The study area encompasses natural zonal pastures in Astrakhan Region, republics of Dagestan and Kalmykia, and Stavropol Krai. By late spring 2023, stabilization of open sand areas and deflated territories was observed over a total area of about 250,000 hectares, corresponding to the situation in 2019 — a period before the intensification of deflation processes in the region. Only in the north of Dagestan and the northeast of Stavropol Krai was there an increase in deflated pasture areas in spring 2023 compared to 2022, which is attributed to the dry conditions in 2022. Additionally, in 2023, the number and intensity of dust storms in the region significantly decreased. The highest number of days with dust storms (6 days) was recorded in the Lagan district of Kalmykia; they were localized and had low intensity. By the end of September 2023, the area of deflated pastures had decreased to 160,000 hectares due to increased precipitation at the end of spring and during the summer. Ground surveys showed that recovery occurred through the growth of annual weed plants, which poses a high risk of deflation intensification under unfavorable hydrometeorological conditions.
