The present study attempts to delineate and prioritize Jumar sub-watershed (subernarekha watershed) for sustainable development using geospatial techniques. The remote sensing products in conjunction with Survey of India toposheet were used to delineate different physiographic units. Seven classes were identified based on depth, slope, erosion, texture, acidity and rock out crops. Out of these classes moderately well drained and very strongly acidic soils occupy largest area i.e. 7765.4 ha (27.07% of TGA). Based on the severity of the problems, the identified classes were again grouped under various priority zones viz., high (severe limitations), medium (moderate limitations) and low (minimum limitations). About 32.38% area was classified under high priority, followed by 29.07% under medium and largest area i.e.7765.4 ha (27.07%) under low priority zones. The high and medium priority zones require immediate protection and amelioration and hence suggested land use plan for sustainable development.
