The present study was taken up to assess the impact of watershed programme on LULC & NDVI using remote sensing & GIS in Muddada Watershed project (2010-2011 to 2017-2018) of Srikakulam dist, Andhra Pradesh. The study was carried out using IRS Resourcessat-2 LISS-IV satellite imageries data of 2011 (Pre 17-Oct-2011) and 2017 (Post 02-Nov-2017) covering the watershed to assess the changes in land use / land cover and NDVI for a period of five years (2011-2017). The images were classified into different land use/land cover categories using supervised classification by maximum likelihood algorithm. They were also classified into different vegetation levels using Normalized Difference Vegetation Index (NDVI) approach. The results revealed that the area under crop land and plantation were increased by 612.42 ha (17.61%) and23.85 ha (1.08%) respectively. This was due to the fact that parts of wastelands and fallow lands were brought into cultivation. This increase in the area may also be attributed to better utilization of surface and ground waters, adoption of soil and water conservation practices and capacity building of the watershed community. The area under current fallow decreased by 209.33 ha (67.34%) and waste lands by 379.26 ha (55.43%). Substantial increase in the area under dense vegetation (35.12%) and open vegetation (26.90%) was also observed. The water body area also increased from 57 ha to 63 ha might be due to rain water conservation activities taken up in the project area.
