Satellite data of IRS- IC/ID for two seasons representing rabi (December 8 and 10, 2000 PAN + LISS III merged) and summer (March 15, 2001 LISS III) were used for preparing thematic maps and suggesting action plans for management of natural resources in Medak Nala watershed. Impact assessment of IWDP programme in Katangidda Nala watershed was done using IRS IC/ID data of LISS III image of December 11, 1997 (pre-treatment) and November 15, 2002 (post-treatment). The water and agriculture resources action plans of Medak Nala watershed were prepared by integrating the thematic maps such as land use/land cover, soil resource inventory, hydro-geomorphology, slope etc. The results indicated that the present land use of the watershed (5,169 ha, 42.58%) is under khan/crop followed by rabi crop area (2,814 ha, 23.18%) and land with scrub (2,280 ha, 18.78%). The 20 soil series of the watershed were classified under Inceptisols, Alfisols, Vertisols and Entisols. The hydro-geomorphology status of the watershed indicates that major area is under plateau moderately dissected (5,200 ha, 42.83%) followed by plateau slightly dissected (3,298 ha, 27.17%) and pediplain shallow (1,750 ha, 14.41%). The drainage network of the watershed resembles a dendritic pattern with drainage density of 2.16 km/sq. km. Based on these conditions, the watershed action plans were prepared. Water harvesting structures like boulder checks (257), check dams (62), nala bunds (10), miner irrigations tanks (2), soil conservation practices like contour farming, strip cropping and vegetative barriers were suggested. In agriculture action plan, agro-horticulture (5,575, ha, 45.93%) plays an important component followed by dryland- horticulture (2,725 ha, 22.45%) and fodder and fuel (2,290 ha, 18.86%).ennullThesis
