The coastal region, especially the Noakhali area, faces constant threats from these powerful storms, with climate change making the situation even worse by increasing both their frequency and intensity. This paper explores how climate change is impacting cyclone shelter management in the Noakhali region, which includes the districts of Noakhali, Feni, and Lakshmipur. While these shelters have saved countless lives, many are now in poor condition, suffering from lack of maintenance and infrastructure that isn’t built to withstand the evolving risks brought by climate change. The study identifies key challenges, such as the need for better upkeep, stronger infrastructure, and new designs that can handle the demands of a changing climate. It also highlights the importance of adapting our disaster management strategies to ensure that shelters remain a safe haven for vulnerable communities during future cyclones.展开更多
