This research is an endeavour to generate foresight physical susceptibility to erosion under SRES A1B business-as-usual scenario of future climate for the entire coastal area of Bangladesh. This study employed Geographical Information System (GIS) based spatial raster model namely, Coastal Erosion Susceptibility Model (CESM) by employing future projections of four climate-induced drivers such as rainfall, wind speed, mean sea level and water discharge along with five underlying physical elements. The outputs are justified through integrating experts’ opinions by developing Fuzzy Cognitive Maps (FCMs). This study identified a total 276.33 km² of land as high and very high susceptible to erosion for overall baseline condition (2015) that would be increased to 453.81 km², 648.63 km² and 1019.13 km² by 2020, 2050 and 2080 respectively. The amount of land for very low susceptibility would be reduced substantially for different time-slices that would turn more lands into high susceptibility in near and far future. This study also addressed seasonal variations of future climate in the assessment whereas, monsoon (June to September) represents very high susceptibility and winter (December to February) characterises very low susceptible to erosion for all of the three time-slices. The increasing scenario of high susceptibility to erosion might be a matter of concern for a densely populated coastal area like Bangladesh. This research might be seminal for coastal managers, policy makers and researchers in managing future coastal lands in the area studied.
