Abstract. In the context of global climate warming, the conditions of functioning of arid territories are changing, which lead to soil and vegetation cover degradation. Currently, the processes of Dagestan pastures desertification are associated with a tendency to increase the area of degraded pasture lands. Of particular concern is the condition of pastures, where sands cover fields, roads, and the territory of settlements as a result of aeolian transport. Geoinformation analysis of desolate lands allows us to determine the current state and establish the spatial location of desertification sites in the research area, as well as to determine the complex of natural and anthropogenic factors that negatively affect the state of pastures. The purpose of the study was to identify the current state of the Kizlyar pastures desolate lands. The research area was selected based on a preliminary study of agricultural landscapes satellite images exposed to desertification processes. The paper presents the results of the current state of the Kizlyar pastures in the desolate lands of the semi-desert zone geoinformation assessment and field research in 2023. At the same time, geoinformation mapping of test polygons was carried out, test sites for field research were identified and their photo ranges were developed. Also the composition of plant communities was determined and their characteristics were established, the degree of land degradation was determined. It has been established that the main type of degradation of pastures is their trampling during grazing, and as a result, the development of deflation processes is observed and large areas are exposed to salinization. The obtained materials can be used for geoinformation analysis of the state of lands and their desertification dynamics in the territory of the Republic of Dagestan.
