Abstract

This study investigates soil erosion and land degradation in the mountainous regions of the Parkent district in Uzbekistan using Geographic Information System (GIS) technologies. The research aims to analyze the extent and severity of soil degradation while examining related factors such as vegetation loss and changes in land use patterns. Advanced spatial analysis techniques and high-resolution remote sensing data were employed to conduct a detailed assessment of environmental transformations within the region. The analysis identifies critical degradation hotspots, revealing the influence of topographical diversity, climatic variations, and human activities, including overgrazing and unsustainable land-use practices. Predictive models were developed to evaluate the future risks associated with soil erosion, offering significant insights into the dynamics of soil fertility and its implications for agricultural productivity. These findings serve as a valuable resource for developing soil conservation strategies and promoting sustainable agricultural practices tailored to mitigate erosion. Furthermore, this research highlights the potential of GIS technologies as an indispensable tool for monitoring, visualizing, and addressing land degradation issues. By harnessing the advanced analytical capabilities of GIS, this research lays a strong foundation for designing precise intervention measures, improving the efficiency of land management strategies, and reinforcing long-term environmental sustainability in mountainous regions that are particularly vulnerable to soil erosion.
