At present, the coastal belt of Bangladesh has 139 "polders" or low-lying tracts of land enclosed by earthen embankments. In all the study areas, settlement area considerably increased over time. The geographical location and climatic condition of the country are responsible for cyclone and other natural disasters. The geomorphology of Bangladesh has always made the country vulnerable to natural hazards such as storm surges, cyclones, inundation, and seawater intrusion. As their heights need to be reassessed, all polders, whether sea-facing or inland, will benefit from mangroves in the foreshore area - the land along the water's edge.
