Soil erosion is the common land degradation problem in the worldwide, and also is one of the most critical environmental hazards of recent times, which reduces productivity. Assessment of soil erosion is expensive and intensively long exercise. In the present study an USLE model has been used for estimation of soil loss for Raigad district of Konkan region of Maharashtra. Conservation practice factors were recommended to reduce the soil loss below tolerable limit. The predicted average annual soil loss by USLE from Raigad district was found as 38.22 t ha/yr before adoption of soil and water conservation measures. About 80% of area from Raigad district comes under severe (20-40 t ha/yr) to extremely severe (>80 t ha/yr) erosion classes. This indicates to adopt soil and water conservation measures on watershed basis for sustainable development of soil and water. It proves urgent need of adoption of conservation measures. Estimated conservation factor was 0.32 to bring the soil loss within tolerable limit. Thus, the soil loss after adoption of soil and water conservation measures for Raigad district was 9.18t ha-1yr-1. Although, study indicates that the soil erosion and crop productivity loss can be effectively used for conservation measures in study area.
