Soil Erosion Estimation of Sivasagar District in Assam Using Revised Universal Soil Loss Equation (RUSLE) Model

Soil erosion poses a serious threat to agricultural productivity and environmental sustainability, particularly in regions with high rainfall and complex topography. This study evaluates soil erosion in the Sivasagar district of Assam, India, using the Revised Universal Soil Loss Equation (RUSLE) model within a GIS framework. The analysis incorporates spatial data on rainfall, soil properties, topography, land use, and conservation practices to estimate annual soil loss. Results indicate that soil erosion rates vary significantly across the district; mostly the region has low to moderate soil loss ranging from 0 to 920.511tons per hectare per year. High erosion rates are observed in the areas adjacent to waterbodies. The study identifies key erosion hotspots, emphasizing the urgent need for targeted soil conservation measures. These findings provide a scientific basis for policymakers to implement sustainable land management practices, crucial for mitigating soil erosion and preserving the region’s agricultural viability.
