Water and wind erosion of land causes annual damage since it leads to soil degradation and loss of fertility, reducing the economic indicators of agricultural production. Detailed systematization of land resources with an assessment of the scale and level of land degradation provides a basis for ranking areas by relevance and effectiveness of erosion protection. The article assesses the level of degradation of agricultural land in the Samara region by the scale of economic losses under the influence of water and wind erosion of soil with differentiation by administrative districts. The map of eroded lands has been developed. The results of integrated erosion zoning of the territory provide an information basis for identifying priority areas requiring anti-erosion measures, as well as for optimizing the structure of agricultural land use. The main directions of anti-erosion organization of the territory and on-farm land management, depending on the features of the landscape and the nature of damage, have been described.
