Cadastral level agricultural resources planning through remote sensing and GIS techniques

An attempt has been made for agricultural resources planning of the village Jalondar (District Junagadh, Gujarat) using Remote Sensing and GIS Techniques. Out of five micro-watersheds in the village area, a micro-watershed having an area of 602.83 ha was selected for preparing the action plan. Maps on various themes such as land use/land cover, soil texture, slope and drainage pattern were prepared using remote sensing image (IRS P6 LISS IV image) and Arc View and ENVI softwares. Arc View software was used for preparation of thematic maps while the Environment for Visualizing Images (ENVI) software was used for registration and superimposition of cadastral map with thematic maps. Rational method was used to estimate the peak runoff rate while curve number method was used to estimate the runoff volume. Information available from various thematic maps was used for designing various soil and water conservation measures such as contour bunding, staggered contour trenches, continuous contour trenches, loose rock dams and water harvesting structures. Annual water storage capacities of suggested structures were estimated at 69.89, 14.10, 9.45, 1.48 and 6.78 ha-m, respectively. The suggested conservation measures fulfill the existing water resource gap (167.76 mm) of watershed at 60% probability of rainfall.
