Synergistic application of satellite remote sensing and geographic information sistem (GIS) techniques were used to analyze the agricultural performace and sustainability of the Bhakra Irrigatin System in India. Although this large wheat-based irrigation System is operated under the warabandi principle of rotational water supply, its high agricultural productivity is supported significantly by heavy withdrawal of groun dwater. Analysis of multidate satellite data during the1995/96 rabi season helped to generate spatially distributed information on total cropped area, area under wheat, andweat productivity per unit area. This information was integrated with other relevant grond-derived data on soil type, water-table depth and its long-term trend, groundwater quality, distributary-level discharge, rainfall, and evapotraspiration in a GIS environment using IDRISI software. The agricultural and hydrologic setting of the command area as well as the long-term trendsin agricultural productivity and ground-water regime was assessed. Diagnostic analysis of problem areas and the development of possible action plans at the regional level are made feasible with information from the GIS on crop yeld, canal water supply, and soil salinity. The study thus demonstrates the synergy possible from applying satellite remote sensing and GIS to evaluate trends in rising water tables and salinity, which are two important threats to the sustainability of irrigation systems. |
