Abstract: The study was reveals to identify the changes of land use/land cover of the Devarahalli microwatershed of Gundlupet taluk, Chamarajanagar district, Karnataka. The study was undertaken with the use of remote sensing and GIS for delineating and planning. For land use mapping the standard procedure has been used and finally with the help of geospatial technology (ArcGIS10.2.2 software version) the mapping was done. Land classification was done and it was showed that, majority of the area in the microwatershed was covered by agricultural land (89.40%) followed by forest (5.05%), water body (3.06%) and built up (2.44%) land. This classification and the land use map will be beneficial to the policy makers, farmers, NGO’s and field agricultural officers for planning and development of this watershed. Also rainwater harvesting techniques can be provided after estimating the runoff potential and accordingly rainwater conservation structures can be planned.
