Vulnerability to Climate Risks
Bangladesh is indeed a hydraulic civilization situated at the conﬂuence of three great rivers – the Ganges, the Brahmaputra and the Meghna. Over 90 per cent of the Ganges-Brahmaputra-Meghna (GBM) basin lies outside the boundaries of the country. The extensive ﬂoodplains at the conﬂuence are the main physiographic feature of the country. The country is intersected by more than 200 rivers; there are 54 rivers that enter Bangladesh from India alone. Moreover, more than 80 per cent of the annual precipitation of the country occurs during the monsoon period between June and September. These hydro-meteorological characteristics of the three river basins are unique and make the country vulnerable to a range of
climate risks, including severe ﬂooding and periodic droughts.
