In the article, the authors turn to identifying the most significant natural and anthropogenic factors that influence the distribution of unused agricultural lands in the Russian Federation. Various classifications of factors according to their status and level of influence are presented. The results of the factor analysis, correlation analysis based on the Spearman coefficient, and the Cattel scree method are presented, which conclude that the most significant of them include the area subject to water and wind erosion, and the area overgrown with trees and shrubs. Specific examples of assessing the territory exposed to these factors are shown. A location assessment and erosion assessment of the land mass subject to erosion processes was carried out. The results of processing data from satellite images using the NDVI index and processing data from satellite images of wetlands in artificial colors are presented. Indicators are given on the basis of which in the future it is necessary to select the most effective use of unused agricultural lands or raise the issue of transferring them to other categories of the land fund or changing the type of permitted use. Proposals are given to identify the degree of suitability of such lands for use in agricultural production.
