Bangladesh is likely to be one of the most vulnerable countries of the world in the event of climate change.It is well known for its natural disasters such as cyclone,storm surges, floods, droughts and river erosions.Rainfall is the major meteorological variable which plays a significant role in the hydrological cycles as well as over agricultural sectors.Under the greenhouse warming condition, extreme daily precipitation will be increasing despite the decrease of mean precipitation.According to the latest assessment report of IPCC (AR5 WG-I) climate change has profound impact on rainfall intensity and variability.The trend of extreme precipitation is increasing globally and consequently the heavy precipitation indices are increasing.This study made an effort to incorporate all climatic extremes alongside with agricultural information for different agro-ecological zones of Bangladesh.
