Land use/land cover mapping and change detection using remote sensing and geographic information system (GIS) technique helps in assessing the land surface information on course scale as well as finer scale. This paper attempts the assessment of land use / land cover changes for the Wainganga Sub-basin which is a part of the Godavari basin. The change detection was done for the last 34 years (19852019) and found significant changes during 2005-2019; before that, the changes were not very noticeable. In the last 34 years, the agricultural land was shrunk by 3.20%, while waste cum barren land reduced by 0.20% of the study area. The shrunk part of agricultural land converted into forest, built-up and urban, and water bodies.The built-up expanded and variation in that period was 106% with respect to the base period.
