Proposing economic development measures for Vatrak sub-watershed

This book describes proposing economic development measures for Vatrak sub-watershed (Sabarkantha District, Gujarat, India) using Geo-informatics based visualization of local environmental parameters and estimation of NDVI. A study was carried out to estimate variation of these parameters i.e. rainfall and groundwater as well as extent of Agriculture area concerning Vatrak sub-watershed. Vatrak, a tributary to Sabarmati River, is a rainfed river. It flows during SW monsoon period. Here, data visualization was carried out using Geospatial Technology. NDVI (Normalized difference vegetation index) was used to estimate the extent of Agriculture area. Inferences were drawn using outcome of Geo-informatics based 2-D, 3-D and 4-D visualization of environmental data. Multi Criteria Evaluation was used to identify potential sites for water harvesting structure. Major section of the society in study area depends on Agriculture and dairy farming. Over the years, competition for water between agriculture, industry and domestic use has increased significantly. Economic development measures of study area have been suggested on the basis of outcome of visualization.
