The earth has transformed ages throughout the world to the service of humankind. In India explosive growth of the population and their growing need has steadily increased the demand to utilize the land resources at optimum for agricultural land, mining and industrial establishment, urban expansion, etc. with the expense of natural forest, grassland, and wetland that had been the valuable habitat of numerous species. Therefore, Land use and land cover change have become significant issues to study resource management and utilization in the present scenario. This study aims to detect the land-use land cover change in Bokaro District of Jharkhand, Eastern India from 2001 to 2021 using Landsat-7 ETM+ and Landsat 8 OLI satellite images. The DOS method has been used for atmospheric correction, and the classification NDVI, SAVI, MNDWI, and NDBI indices were first calculated. Afterward, K means unsupervised classification has been used to generate land use and land cover maps through the SCP plugin in QGIS. For the accuracy of classified land use and land cover maps, a confusion matrix & kappa coefficient were used to derive overall accuracy and the results were above the minimum and acceptable threshold level. The massive changes in land use land covers are noticed in vegetation, agricultural land, mining, allied activities, and waterbodies. The result reveals both the increase and decrease of the different land use/ land cover classes from 2001 to 2021. An appreciable increase in vegetation cover and a marginal decrease in the mining area was noticed.
