Kalapara is one of the most climate-vulnerable locations in Bangladesh. Climate Change and Water Resources 2.4. Among other consequences of climate change, sea level rise is one of the most severe threats to Bangladesh. Similarly, 70% of coastlines is expected to experience a sea-level change within 20% of the global mean sea-level change. Climate change-driven sea level rise is expected to trigger growing waves of migration away from coastal areas globally. 5 Accelerated sea-level rise caused by global warming 6 is putting added stress on land, water, and food in this already at-risk region. As sea levels rise, Bangladeshi islanders must decide between keeping the water out—or letting it in. Possible loss of land through beach erosion due to sea level rise on the eastern coast of Bangladesh is examined. Both livelihood options of coastal communities and the natural environment of the coastal zone will be affected by the anticipated sea level rise.
