Climate change impacts and adaptation assessment in Bangladesh

Bangladesh is likely to be one of the most vulnerable countries in the world to climate change. This paper discusses the possible impacts of climate change in Bangladesh through tropical cyclones, storm surges, coastal erosion and back water effect. The possible increase in cyclone frequency in the Bay of Bengal, lying south of Bangladesh, due to climate change is looked at by analyzing the cyclone data for 119 yr. Both qualitative and quantitative discussions are made on cyclone intensity increase for a sea surface temperature rise of 2 and 4C. Different scenarios of storm surges under different climate change conditions are developed by using a numerical model of storm surges for the Bay of Bengal. Possible loss of land through…
