Chattogram
Bangladesh
Chattogram is projected to face severe climate hazards that threaten its environment and health. The city will experience more frequent and intense heatwaves, raising health risks. Heavy rainfall events are expected to result in flooding and increased waterborne diseases. Additionally, prolonged drought conditions may disrupt water supply and agriculture, threatening economic stability. The risk of arbovirus transmission is notably elevated, alongside heightened malaria risks due to a warmer climate. These interconnected challenges are likely to strain local healthcare systems and infrastructure, emphasizing that Chattogram faces a complex web of vulnerabilities that demand urgent attention.
