Land is germane to all forms of life. Land provided the stage on which the human drama was played out as well as the tools with which this drama was enacted. Incremental human activity on land however did not leave land itself untouched. Land has been subjected to varied land uses and landscapes have been variedly modified. Bist Doab is not an exception to this scenario. There have been some notable changes in land use in the Bist Doab during the last fifty years. Human activities also have profoundly changed the land use and land cover in Bist Doab and it can be shown as uncontrolled development that can be analysed through land use and land cover change detection in Bist Doab. Land use and land cover change detection resulted out through the analysis of land use and land cover change over the two time period vis-a vis 1975 and 2015. This study provides a base to understand, how man modified the land according to his needs from past to the present time. Landsat 1975 and 2015 images were used to detect land use and land cover change. The whole study area is classified into 9 categories as followed respectively rivers, reservoirs, dense scrub, open scrub, agricultural area, current fallow, barren area, built-up area and sandy area. The study concludes that agricultural area and built-up area has been increased at a fast rate while rivers, reservoirs and current fallow have a marginal increase in their total area. Whereas barren area, dense scrub and open scrub has shown a decrease. Thus, satellite images and use of GIS provides efficient tools to analyse land use and land cover change detection in Bist Doab.
