| Abstract | ||
The Som river catchment lies in districts Udaipur, Banswara, Pratapgarh, Chittorgarh and Dungarpur. It extends from 73° 32’ E to 74°50’E and 23° 50’ N to 24° 58 N, respectively. It is located in southern most part of the Rajasthan. It is right bank tributary of Mahi River. In this study, a very common method of monitoring surface vegetation health, (NDVI) Normalized Difference Vegetation Index has been used. In this study, Satellite imagery LANDSAT-5 TM for the year October 1994 while for year October 2015 satellite image LANDSAT-8 OLI TIRS has been used. The two corresponding year map of 1994 and 2015 shows clear decline in the health of the vegetation. The Eastern, Southern and Northern region of the catchment were subject to severe vegetation lose during this period. |
