Land cover change and its impact on human-elephant conflict: a case from Fashiakhali forest reserve in Bangladesh

Changes in land cover are a major driving force behind habitat change, which significantly impacts the distribution of wildlife and ecological systems. However, there is a substantial lack of information on the effects of land cover changes on wildlife habitat and local conservation. Therefore, it is essential to understand how land cover changes may threaten future land cover trends and wildlife habitat loss, especially in protected areas. Landsat satellite imagery uses a geographic information system and remote sensing techniques to determine the spatiotemporal pattern of land cover change and its impact on the human-elephant conflict in the Fashiakhali Wildlife Sanctuary. We found that within the sanctuary (1994-2005), settlements, agricultural land, and bare land increased by 69.8ha (2.3%), 991.6ha (32.3%), and 39.5ha (1.3%), and forest areas and water areas decreased by 1094.1ha (35.7%) and 6.9ha (0.2%), respectively. On the other hand (2005-2015), settlements, agricultural land, and water areas increased by 11.7ha (0.4%), 264.7ha (8.6%), and 36.2ha (1.2%), and forest areas and bare land decreased by 308.9ha (10.1%) and 3.7ha (0.1%), respectively. Our findings have shown that increased agriculture and settlements have become a severe threat to the ecological sustainability of elephant habitat, resulting in habitat fragmentation and human encroachment of elephant habitats, as well as extreme pressure and competition on resources.
