The presented article analyses the main factors that play a role in the formation of the desertification process in the landscape complexes of the Mill plain. It has been determined that anthropogenic changes in hydrogeological conditions and cattle-breeding have a special role in the emergence and development of desertification in the area. 85% of all desertification centers in the studied region were caused by these factors. Natural factors mainly cause the intensification of desertification or the formation of desertification symptoms. When calculating the total annual income for desertified areas, the intensity of the annual decline in productivity since the beginning of the desertification process should be taken into account. In this case, in addition to anthropogenic factors that directly affect the soil, the influence of meteorological factors that play a significant role in soil productivity is also taken into account. Taking into account the mentioned factors, using Landsat-8 OLI/TIRS satellite images and Google Earth satellite observation data, a 1:100000 scale map reflecting the degree of desertification of landscapes was drawn up based on ArcGis software. It was determined that 4,9% of landscape complexes were subjected to varying degrees of desertification, 0,6% of them were slightly desertified, 29,8% were moderately desertified, and 18,5% were severely desertified. Conditionally non-desert geocomplexes make up 51,1% of the total area.
