MONITORING OF SOIL AND LAND RESOURCES USING REMOTE SENSING METHODS: EXAMPLE OF THE MYRHOROD DISTRICT OF THE POLTAVA REGION, UKRAINE.

Abstract

Rational use and protection of soil and land resources are key factors in ensuring food security, enhancing agricultural productivity, and preserving the environment. Due to the intensive agricultural activity that covers a significant part of the territory of the Myrhorod District in Poltava Region, there is a pressing need for systematic monitoring of land conditions. Such monitoring is essential for timely detection of negative changes and for making informed management decisions regarding soil conservation and restoration. This study substantiates the feasibility of using modern remote sensing (RS) methods for collecting, processing, and analyzing information about the condition of soil cover. The use of high- and medium-resolution satellite imagery, calculation of vegetation indices (such as NDVI and SAVI), and integration of these data into geographic information systems (GIS) allow for spatially detailed and up-to-date information on land use structure, vegetation cover, and potential signs of land degradation. The results of the analysis made it possible to identify key trends in land use changes, to localize areas affected by erosion, salinization, compaction, or reduced fertility. This, in turn, provides a basis for developing practical recommendations to improve agricultural production, implement soil protection technologies, and plan land use more effectively. The application of RS methods combined with GIS analysis enhances the quality of monitoring while reducing time and resource costs compared to traditional survey methods. The results presented are of practical relevance for local authorities, land management services, agricultural enterprises, and environmental organizations involved in the management and protection of land resources.
