Desires for In Situ Adaptation Versus Out‐Migration? The Impact of Flooding and Cyclones on Polder Communities in the Bangladesh Delta

Journal article

In Bangladesh's delta, rural communities have long held lives inseparable from seasonal flooding, adapting their homes and livelihoods to the annual monsoon. However, land subsidence, changing seasons, severe storms, increased salinity, and rising sea levels are threatening local livelihoods. The objective of this paper is to understand rural residents' perceptions of climate impacts and adaptation measures, focusing on their mobility choices. Through 15 qualitative, semi‐structured interviews with 22 representatives from two embanked polder localities in southwest Bangladesh, we explored the following questions: (i) How do local residents perceive recent climate and environmental changes? (ii) How are local residents coping with these changes and what external assistance do they require to maintain their livelihoods; and (iii) How do local residents perceive migration or partial migration as a potential adaptation strategy? While these communities report an increased frequency of extreme climate events and severe flooding, our findings also reveal a lack of external assistance for adaptation solutions. Moreover, most families are either unwilling or unable to completely migrate out of affected areas. Therefore, increased support—the provision of fresh drinking water, money to recoup lost income and assistance rebuilding or reinforcing homes—is essential for building adaptive capacity and increasing local resilience in the face of climate shocks.
