The world's natural ecosystems are impacted by changes in land use and land cover (LULC), which are a dynamic, pervasive, and accelerating process primarily driven by anthropogenic activities and natural disasters. One of the objectives of landscape ecology is change detection. This study's primary goal is to prepare land use, land cover, and their change detections utilising GIS and remote sensing techniques. The changes in Talwara Block's land use and land cover between 2001 and 2021 are shown in this study. Landsat5 & Landsat8 imagery from 2001, 2011 and 2021 was used for the investigation. With the application of remote sensing and GIS technology, categorization maps for land use and land cover were created. The results indicate that there was a significant increasing trend in built up land and decreasing trend in agricultural Land and forest cover.
