LAND USE/LAND COVER STUDY USING REMOTE SENSING AND GIS TO ASSESS THE PHYSICAL CHANGES IN THE SABARMATI RIVER BASIN, GUJARAT

Abstract

Land use/Land cover (LULC) is an essential mapping in sustaining and preserving our environment. The present study aims to analyze the changes in LULC for three decades by comparing classification statistics using Remote Sensing and GIS technology. The sub-basin of the Sabarmati River was selected for the study to measure the parameters of the decadal landscape changes to determine the minimum and maximum changes depending on climate change parameters. Future predictions are also performed to better understand the changes in the region to extract the information matching the current land use. The result indicates that during 2000 to 2030, agricultural land has increased along with the built-up area. Observations have also been done about river /water bodies area, which is also increased potentially; fallow land patches saw a reduction significantly while Barren land has increased. Lastly, Vegetation patches have also decreased by increasing agricultural and infrastructure activities. The result shows that urbanization is growing along with the agricultural land, while vegetation patches are falling.
