Soil erosion, a vital environmental concern, results primarily from human activity such as deforestation, agricultural expansion, and urbanization. The Gimbora River catchment, known for its diverse topography and climate, has not been immune to these shifts. As agricultural practices evolve, the natural vegetation cover has diminished, leading to increased vulnerability of the soil structure. This study utilized advanced remote sensing technologies and Geographic Information Systems (GIS) to monitor land use changes and assess their implications on soil erosion risk throughout the region.

The methodology employed in this study involved a multi-faceted approach, integrating satellite imagery analysis to identify significant land cover changes over a specified timeline. By analyzing historical and current data, the researchers were able to pinpoint alterations in land use, particularly differentiating between cultivated lands, grazing areas, and forested regions. This quantitative assessment provides a robust foundation for understanding the dynamics of soil erosion within the catchment area.

One of the key findings of this research is the direct correlation between the expansion of agricultural lands and the increase in soil erosion potential.
