A number of sectors in Bangladesh are likely to get affected by the potential changes in climate. A number of studies have analysed the impacts of climate change on agricultural crops, mainly rice, in Bangladesh. In Erda L et al . Climate Change Variability and Adaptation in Asia and the Pacific . Higher CO 2 levels have a positive influence on rice yields.
Higher temperatures have negative influence on rice yields in all seasons and almost all locations.
The net effect of temperature and carbon fertilization is negative on rice yields. In addition to the above impacts, agricultural areas in Tropical Asia in general, and Bangladesh in particular, are vulnerable to many environmental extremes such as floods, cyclones, and storm surges. Agricultural production from Bangladesh has been severely affected due to floods over the years. Under changed climatic conditions, the frequency of climate extremes is expected to change. Hence, for the true assessment of total impacts, one should quantify the likely losses due to extreme events as well.
