The impact of land use and land cover changes on soil erosion in western Iran

Analysis of long-term land use and cover (LULC) changes requires up-to-date remotely sensed data to assess their effects on erosion. This is a particularly important assessment for regions with semi-arid landscapes where soils tend be scarce proper management necessitates matching LULC local conditions achieve sustainable use. study evaluates the impact erosion using Landsat satellite imagery Revised Universal Soil Loss Equation model plains around Jarahi River Shadegan International Wetlands.
