Introduction: why is flood risk in Bangladesh so high? Nearly 60% of Bangladesh’s population is exposed to high flood risk, a greater proportion of the population than in any other country in the world other than the Netherlands, and around 45% are exposed to high fluvial flood risk, the highest figure in the world (Rentschler et al., 2022). [...] Sea level rise: The sea level rise experienced as a result of global warming in flash flooding, is increasing the duration of floods and the size of the flooded area in low- lying Bangladesh, due to the backwater effect of the sea (Ali et al., 2013). [...] rising sea levels and A rise in sea level of 0.53 metres under 1.5°C to 2°C of warming2 by 2100 is predicted to result in 16% of the land area in Shariatpur and 7.4% of the accelerated glacial land area in Chandpur being permanently submerged (Davis et al., 2018). [...] These changes in land use and land cover have increased the risk of flooding, especially in urban areas: and because of their for example, increasing the risk of subsidence, creating more impermeable low capacity surfaces, and removing the stabilising effect of trees.
