Bangladesh faces a severe threat from climate change, with a new report indicating that up to 18% of its coastal areas could be submerged by 2100 due to rising sea levels. The joint report by the Bangladesh Meteorological Department (BMD) and the Norwegian Meteorological Institute highlights various climate challenges, including rising temperatures, intense monsoon rains, and increasing storm surges.
Currently, coastal regions experience sea level rise of 3.8 to 5.8 mm annually, nearly double the global average, influenced by both natural geological processes and human activities, leading to land subsidence. Projections suggest that global sea levels could rise by up to 1.01 meters, significantly affecting low-lying areas like the Sundarbans and Bhola Island.
The report emphasizes the heightened risk of flooding, especially under extreme weather conditions, which has previously led to mass evacuations and severe impacts on agriculture and freshwater sources. Vulnerable populations, particularly children and the elderly, face increased health risks from heat waves and the spread of vector-borne diseases.
Moreover, the agricultural sector, vital for the economy, is projected to suffer from heat stress, salinity, and flooding, endangering food security. Ecosystems, including the Sundarbans mangrove forest, are also at critical risk of loss.
Despite Bangladesh’s notable efforts in climate adaptation, experts emphasize that effective international action is crucial for mitigating global emissions and protecting millions of lives at risk. The decisions made today will shape the future of the country’s land and livelihoods, as significant portions could be lost by 2100 if current trends continue.
