Historically, southern coastal Bangladesh, where the 1970 Bhola Cyclone killed 500,000 people, has been considered among the most climate-vulnerable environments on Earth. However, in recent decades, extreme weather events, like Cyclone Aila, though still destructive and destabilising, have resulted in lower death tolls thanks to a concerted investment in flood mitigation infrastructure, a dense network of cyclone shelters and a robust early warning system . Cyclone Aila struck the southwest coast of Bangladesh on 25 May 2009 with a wind speed of 120 km hour-1 . With tidal surges of up to 6.5 m, occurring over dry pre-monsoon soils, 11 coastal districts and more than 3.9 million people were affected , 190 people died and 7100 people suffered injuries .
