Abstract
This research focuses on the crucial role of slope steepness in agricultural land management within the Vinnytsia urban territorial community, recognizing its impact on land productivity, erosion, and crop suitability. Employing GIS technologies and digital elevation models (DEMs), the study analyzed terrain characteristics to develop slope steepness maps. The methodology involved using QGIS software with the GRASS plugin to generate DEMs from contour lines, derive slope aspect, and calculate slope steepness.
The findings highlight that a significant portion of arable land (96.6%) in the Vinnytsia community is on slopes up to 3°, belonging to the first ecological and technological group (ETG I). However, 3.0% falls within ETG II (3°–5° steepness) and 0.4% within ETG III (steeper than 5°), necessitating differentiated land use approaches due to elevated erosion risks. The study proposes specific erosion control measures and restrictions for steeper lands, including conservation agriculture principles, exclusion from intensive use, and transformation into pastures or forest plantations for ETG III lands. This GIS-based analysis provides accurate data for effective spatial planning and sustainable agricultural practices in areas with complex terrain.
