Theme 8-9-Geographic information system (GIS) approach for sustainable land resources development of watershed.

Abstract

A study was taken up in 'Yacharam' watershed of Ibrahimpatnam block of Ranga Reddy district, Andhra Pradesh (17O00/ to 17O05/ N latitudes and 78O35/ to 78O45/ E longitudes) to map different basic natural resources of watershed viz., land use/land cover, hydro-geomorphology, soil and topography from remote sensing (IRS-IB, LISS-II) as well as conventional data sources and analysis of these maps through geographic information system (GIS). After mapping all the basic natural resources, composite land development unit map was prepared through GIS and action plan for alternate sustainable land development systems like agro-forestry, agro-horticulture, inter-cropping, intensive agriculture, silvipasture, horticulture, salt-resistant crops etc. were suggested in different parts of the watershed.
