In Bangladesh, impacts on agriculture from extreme climate are increasingly vulnerable. On the other hand, folk communities are intensely depending on agriculture for their livelihoods. Climate change has already negatively affected the vegetable production by annual recurrent flood in Bangladesh. This study is an assessment of the new vegetable production system that could adopt in a changing climatic condition. With the popular eight vegetable species, the field experiment consisted of four treatments which were conducted in the bags. However, treatment (TD) which consisted of Coriander (Coriander sativum), Pumpkin (Cucurbita maxima), Bitter melon (Momordica charantea), Tomato (Lycopersicon esculeatum), Cowpea (Vigna sinensis) is more beneficial than our other treatments. The average benefit ratio of this treatment is 9.75 followed by 6.52 (TA), 5.45 (TB) and 5.17 (TC). Moreover, the findings of this study might be helpful for the flood affected folk communities produce vegetables for their own consumption and income. Likewise, new experiments with altered technique and vegetable species are recommended to conclusively develop climate change adaptation strategies for flood prone areas.
