Spatial and temporal dynamics of degraded lands in the Cogalnic basin in the 21st century

Abstract

The paper analyses the degree of damage to the territory of the Cogâlnic river basin by landslides and linear erosion, characteristics expressed by numerical indices as the ratio of the areas affected by these processes to the total surface of the reference territorial unit. For this, cartographic models of the dynamics of degraded land areas were developed for the years 2004 and 2020. The main territorial units that need to be protected to mitigate linear erosion are highlighted.
