Abstract
Urban areas in India are growing rapidly along with increase in industrial expansions and installation of modern infrastructural facilities which creates a demographical pressure and bring changes urban environment. The Land Use and Land Cover (LULC) are the parameters changes in due course of time and places. Therefore, LULC analysis is essential to know the developmental trends in urban areas through the change in land use patterns of Chhatrapati Sambhajinagar. In present study the Spatio-temporal LULC changes were analyzed in the study area by using GIS tools and techniques. Maximum likelihood supervised classification is used to produce LULC maps, backed by statistical and analytical methods of confusion matrix or error matrix to gain precise outcomes. The results revealed that, the land use land cover changed significantly from year 2011 to 2023 especially in built-up area in city area which was increased by 1.6% and agricultural land decreased by 6.8%. There was a significant increase of 8.7% in barren land in and around city area and tree cover has been dropped by 3.6%. Overall accuracy of the error matrix is 83% and 90% respectively. The downslide of agricultural land and tree cover is the result of an upswing of urbanization and confirming degradation of natural vegetation in study area.
