Land Use and Land Cover Change Detection of Teknaf Upazila Due to Rohingya Crisis by Using GIS, and RS Techniques

Abstract

Bangladesh is in a terrible condition due to forced migration of Rohingya refugees from Myanmar to Bangladesh. Study focused on mapping and estimating changes in Teknaf Upazila's land use and land cover (LULC) between the years of 2010 and 2022. For the purpose of conducting this study, both primary and secondary data have been collected. The study found that the growing population has created unexpected and uncontrolled changes in LULC. It was found that between the years of 2010 and 2022, there was a drop in forest (1.68 SKM), vegetation (10.99 SKM), and bare soil (10.71 SKM). It was found that residences (22.96 SKM) and water bodies (42 SKM) increased during the course of these twelve years. Unplanned construction of refugee camps, political unrest, consumption of wood from surrounding forest, and the large influx of Rohingya refugees into the area are main causes for rising built-up area and drastic reduction of vegetation. As a result, the Rohingya population put pressure on Teknaf's established natural surround-dings and land cover.
