摘要
Climate changes imposed differential impacts on Bangladesh in the form of sea level rise, extreme events, and variability, which has enormous economic, environmental and social cost. Such impacts are assorted across the ecosystems of the Southwest, Northwest and Central region of the country. Among the different sectors, agriculture is comparatively more vulnerable to climate change impacts. In order to reduce the climate change induced loss and damage, a series of adaptation options have been being practiced by the people at the local level for many years, but the effectiveness, profitability, and sustainability of such adaptation options are still not too well investigated or understood. From this backdrop, the study intends to identify, prioritize and evaluate the adaptation options in the agriculture of different ecosystems of Bangladesh. It is found that the economic gain of adopting rice prawn farming, replantation of rice, and saline tolerant and short duration rice varieties are much higher than the other adaption options. Through investing $10 in such adaptation options, $22, $4, $2 and $2 net return will be provided, respectively. Unavailability and less affordability are impeding the promotion of some effective adaption options, which require more attention from policy makers, while further research, demonstration and capacity building of the farmers will reduce vulnerability and build resilience.
