Globally,
Soil erosion is the major land degradation problem, which impacts seriously on
economic and environmental status. Geospatial techniques support and provided
quantitative approach to estimate soil erosion in different conditions. In the
present study, Revised Universal Soil Loss Equation (RUSLE) integrated with GIS
has been used to estimate soil loss in the part of coastal Odisha system. The
study area, Ganjam block have undulating topography covering 0-35% slopes. The
quantitative soil loss was estimated and classified into different classes and
soil erosion map was generated. The soil erosion map is classified into seven
classes from very slight (<5 t ha-1 yr-1) to extremely
severe (>80 t ha-1yr-1). The results indicate that
90.9% (22330 ha) of the study area falls in very low erosion category, which
may be due to level topography and regular vegetation cover. The other erosion classes such as moderate,
high and very high erosion occurred in the range of 2.12%, 2.23% and 1.49 %,
respectively. The high soil erosion risk is spatially situated in the
foothills and upper steep slope of the area. The results can certainly aid in
implementation of soil management and conservation practices to reduce the soil
erosion in the coastal Odisha regions of Eastern India.
