Abstract
This study reveals the changing Land Use Land Cover (LULC) of Nalbari Revenue Circle situated in Nalbari district of Assam during 1991 and 2023 using geospatial approach. Supervised classification was executed over Landsat satellite images for the years 1991 and 2023 respectively to identify the land transformations. The LULC classification considered four main LULC classes namely vegetation, agriculture, water body and built up. Vegetation and water body have decrease by 7.61% and 34.06% respectively during the study period, while built up area and agriculture has increase by 23.72% and 17.95%respectively. Population growth and infrastructure development are identified has major driving factors leading to the changing pattern of LULC in the study area. The substantial alteration of land surface, primarily caused by human activity, has raised concerns about the environment.
