Flooding in Bangladesh will increase by up to 40% this century as global temperatures rise. Each year, about 1/5 of Bangladesh floods. As global warming increases, sea levels will rise, monsoons become wetter and more intense cyclones will lead to higher tides. Bangladesh is flood-prone because it lies in the delta of three rivers: the Ganges, Brahmaputra and Meghna. People can grow crops on the land because it is regularly fertilized by nutrient-laden silt from the rivers. But extreme floods are part of life as well, and in 1988 and 1998, over 2/3 of the country was under water at some time.
Water resources expert Monirul Qader Mirza fed weather data into a computer and discovered that a temperature increase of only a few degrees will increase the flow of the Meghna and Brahmaputra rivers by 20%. There will also be a big increase in deeply flooded land, that?s covered in several feet of water for 9 months of the year, reducing the land available to grow crops.
Ever since it gained independence from Pakistan in 1971, Bangladesh has been a country filled with environmental disasters and frequent famine. In the future, it may be a country that no longer exists.
