Climate Change Impacts on Extremes in Bangladesh: Floods and Cyclonic Storm Surges
A.K.M. Saiful Islam:  Bangladesh University of Engineering and Technology (BUET)
People in South Asia, where people’s livelihoods are highly dependent on water resources, can be affected disproportionally under the warming world. The Ganges-Brahmaputra-Meghna (GBM) river system plays a key role in the survival and development of more than 670 million people in South Asia. This talk discusses how freshwater availability and climate extremes such as floods and droughts of the GBM river basins in Bangladesh will likely be affected by global warming at different warming levels, using a hydrologic modeling analysis of the flows in the GBM river system utilizing multi-model regional climate projections. How the results of this study were used by the Bangladesh government to develop guidelines for climate-resilient infrastructures in the northwestern flood-vulnerable areas, along with adaptation options for agricultural and water management of these three river systems will also be discussed.
