According to the Intergovernmental Panel on Climate Change (IPCC) special report on the regional impacts of Climate Change (IPCC, 2007a), a drastic change in rainfall patterns in the warmer climate would occur in Bangladesh, and it may experience a 5% to 6% increase of rainfall by 2030 due to glacier melting and more intense monsoons, which will create frequent large and prolonged floods as well as an increase in droughts outside the monsoon season. Furthermore, in the context of global warming, most of the climatic models project a decrease in precipitation in the dry season and an increase during the monsoon season in south Asia (Christensen et al., 2007). This will cause a combination of more extreme floods and droughts in this region. Therefore, the moderately drought-affected areas will be turned into severely drought-prone areas within next 20 to 30 years (IPCC, 2007b).
