Watersheds are crucial to food security and rural livelihood. The management includes integrated use of vegetation and water resources to raise agricultural productivity and rural income ensuring food security. Mapping water resources, monitoring the temporal changes of watersheds or catchments and identification of potential ground water resources are the main ingredients in managing water resources. There are no other technologies than GIS and remote sensing to generate this information. Geospatial technologies, particularly GIS and remote sensing can be used to identify changes, vulnerable areas and potential areas for watershed development.
