Abstract: The strategy for sustainable development of rural areas for the period up to 2030 has planned significant amounts of forest plantations, and science has proven their high efficiency for the crop industry-they stabilize agricultural production, increase its safety, act as an insurance measure against emergencies from natural anomalies, control erosion and deflation on arable land. In addition to successfully solving the tasks of the agro-industrial complex to stabilize degradation processes in agricultural landscapes and ensure stable yields, plantations have a certain potential for expanding the share of the forest sector in the regional economy. The cornerstone in assessing the effectiveness of forest reclamation is the practice that is traditionally based on taking into account only additional crop production, the so-called "increments" of the crop. The article proposes to develop this approach towards the overall environmental impact of plantings on adjacent fields, focusing primarily on their soil protection functions, reducing soil losses to acceptable limits. On the example of slope arable land, where there is a risk of water erosion, the optimal protective forest cover of this arable land is modelled. For each technological variant, the costs of creating forest-reclamation complexes and their various utilities are estimated, and the mathematical approximation of the regularities of the dynamics of the effectiveness of these measures is made depending on a wide range of forest and orographic conditions, and the service life of plantings. The conducted research makes it possible to conclude that it is advisable to develop slope arable land for forest reclamation and is a sufficient basis for stimulating the increase of protective forest cover in erosive-dangerous regions.
