Bangladesh is highly vulnerable to extreme weather events due to its frequent exposure to floods and extensive low-lying areas. Coastal flood risks are expected to increase due climate change. Therefore, Bangladesh has been upgrading its coastal embankment system to enhance flood safety. This initiative includes not only hard flood defense infrastructure, but also nature-based solutions through planting mangroves on the seaside of embankments. Mangroves, serving as natural flood barriers, have been utilized in Bangladesh for coastal protection since the 1960s. However, their integration with embankment designs and their benefits in carbon sequestration remain underexplored. This paper consolidates current knowledge on the role of mangroves in coastal resilience in Bangladesh, incorporating recent studies and new analyses on their benefits on (i) flood risk reduction, (ii) livelihood enhancement, and (iii) carbon sequestration.
