The article studies an issue of application of remote sensing technology for determination of arable land degradation. Under the modern land use conditions, the processes of soil layer destruction, particularly on arable land, have been recognized as negative large-scale development factor. It is caused byimpact of excessive anthropogenic processes on agriculture land. The authors analyse determination of arable land degradation, using data of transformations of the vegetation cover, referring to the space multispectral satellite images Landsat. The process of investigationrequires anti-erosion organization of the territory. While processing multispectral satellite images, the principal task is to reproduce the information, which provides the best depiction of the processes of arable land degradation. Transformation of vegetation cover and dynamics of the processes of soil erosion have been chosen as indicators, characterizing arable land degradation. To measure these indicators, it is necessary to use multispectral satellite images of the medium spatial resolution along with supplementary geospatial data -digital model of topography, soil map and climatic characteristics of the studied territory. The authors of the article have performed estimation of the erosion processes by determination of the Normalized Difference Vegetation Index (NDVI). According to the results of the conducted research, the authors have developed thelocal level thematicland degradation map on the territory of village Velyka Ozymyna in Lviv region.This map demonstrates that in the period 2000-2019 18 % of the studied territory was subjected to degradation processes. Considering the discovered changes in land use, the authorsperformed modelling of the expected land degradation level on the studied territory by 2050.According to the data of modern remote sensing, it is possible to make forecast concerning the progress of soil destruction and arable land degradation in the future. It will secure efficient decision-making on optimization of agricultural land use and land protective activities.

Aim of the studyThe aim of the article is to analyze current approaches and investigate some possible new approaches to planning and implementation of restrictions related to the protection of water and aimed at the regulation of land use. Material and methodsThe proposed approach to surface water protection suggests imposing water protection restrictions of land use. This requires developing a land use management project. Designing water protection zones and nearshore protective belts is based on the consideration of options generated by geo-information modeling and use of remote sensing data. The operational options of ArcGIS 10.7 were used as basic software for the performance of the spatial analysis of data. The research territory for seeking confirmation of the proposed methods of projecting water protection zones and near-shore protective belts covered a part of the Seret river and its basin, located within the administrative borders of the Zalishchyky district of the Ternopil region. Results and conclusionsThe results of our research demonstrate that development of a land management project consisting in establishing water protection zones and near-shore protective belts with a specific regime of farming within relevant borders should become one of the most important mechanisms to prevent contamination, reduce flood risk, and improve sanitary-hygienic conditions of water-defined entities, processes, and activities. While developing the land management project, the authors performed calculation of the width of the water protection zone according to the principle of the reference value of an optimal width of the belt, which could catch the surface slope runoff.
