Abstract

Bangladesh is vulnerable to third order impact of climate change, due to its geographical position, over population and economic condition. The research aimed to focus on the variation of rainfall and temperature over an area of agricultural importance zone of GBM (Ganges–Brahmaputra–Meghna) delta system in Bangladesh. Arc GIS 10.1 software (spatial analyst tool) was used to present the spatial distribution and variation of temperature and rainfall over G-B-M delta. Microsoft excel was used to conduct the percentage change calculation. Highest total average rainfall was observed in the Meghna river system area 52917 mm from 1985 to 1994 and lowest total average rainfall was in Brahmaputra river system 20185mm from 2005 to 2014. Beside highest and lowest temperature was 31.90C and 29.510C from 2005 to 2014 in Ganges and Brahmaputra river system respectively. Highest percentage change in rainfall was in Khepupar -0.016069504mm and temperature was in Sylhet 0.0384356040C in Ganges-Padma and Meghna-Surma river system respectively in Bangladesh. Lowest percentage change in rainfall was in Mymensign -0.264142107mm and temperature was in Madaripur 0.0038610040C in Meghna-Surma and Brahmaputra-Jumna river system respectively. Due to the change in climatic variable GBM delta‘s agricultural system faces some severe problem as drought. As a result Bangladesh reaches to a question of food security.
