Abstract

A study was under taken to identify and map the changes in land use and land cover over a period of (1992 to 2017) 25 years in an area irrigating with treated industrial waste water using remote sensing and GIS technologies. Four LANDSAT TM and ETM+ images of 1992, 1999, 2006 and 2017 with a spatial resolution 30mx30m were used to determine the temporal land cover changes. Consequently, ground truth confirmation was done in the study area. Supervised classification was carried out in ArcGIS to identify the LULC classes. The study area was classified into four major classes; Water bodies, Settlements, Vegetation and Fallow lands.  The study revealed that fallow lands was decreased by 99.8%, vegetation was found to be increased by 90.2%  and settlement area was found to increase by 65.7 % over the period of 15 years. Livelihood increased with increased socio-economic status of the people.
