LANDUSE AND LANDCOVER CHANGES AND THEIR GEOENVIRONMENTAL IMPACTS IN NACHOLE UPAZILA UNDER CHAPAI-NAWABGANG DISTRICT OF BANGLADESH: A RS AND GIS APPROACH

This study has been carried out to distinguish the changing pattern of land use and its geoenvironmental impacts on of Nachole Upazila of Chapai Nawabganj District in the Division of Rajshahi, Bangladesh. This study investigated the changes in land-use and land cover of Nachole Upazila. Satellite images were analyzed to detect changes in land use and land-cover in the last 34 years in Barind tract of Nachole Upazila of Bangladesh. The Increase of vegetation cover and changes in land use pattern has been investigated using remote sensing satellite data. Digital analysis found the significant changes, particularly on the burned land that has been transformed mostly into vegetation (Rahman & Rahman, 2007). The study found that during the last 34 years (1983-2016) 26,484.9 hectares of the bare soil area has been converted into Garden and 5306.4 hectares to settlement. The main objectives of the study were to find out the landuse changing patterns and its Geo-environmental impacts due to these changes on Nachole Upazilla of Chapai Nawabgonj District in the Division of Rajshahi, Bangladesh.
