Effects of "Climate Induced Monsoon Flooding" on Land and Population: Land Inundation and Population Exposure Level Due to Climate Induced Monsoon Flooding:a Case Study of Gaibandha District Md. Tajminur Rahman

If rainfall increases due to climate change in the GBM basin that will create huge water flow through the rivers of Bangladesh. Efforts have been made to examine the increase of occurrence of characteristic flood over the historical years. Time series water flow of Jamuna River at Bahadurabad of Gaibandha district is available from 1956 to 2007. Eventually the monsoon flood will be more devastating due to increase of precipitation and sea level rise that may cause more damage to crops and properties if adaptation measures are not taken. In this study, analysis shows that the land inundation and population exposure level of Gaibandha district due to climate induced monsoon flooding in 2040 since impact on land type also determines the change on agricultural yield as it is associated with cropping pattern. In order to devise adaptation options to make Bangladesh climate resilient, it is important to know, the extent, intensity and magnitude of impacts of climate change and its implication on livelihood and food security.
