Douala
Cameroon
Douala is projected to face significant climate hazards in the future. It is likely to experience frequent heatwaves alongside heavy rainfall events, leading to increased flood risks. Additionally, the city will encounter prolonged drought conditions that could strain water resources. These climatic variations will also elevate the risks of arbovirus transmission and malaria, significantly threatening public health. The confluence of high temperatures, heavy precipitation, and drought creates a complex web of vulnerabilities that could impede both community well-being and economic stability. Addressing these risks requires proactive measures and adaptation strategies to mitigate the impacts on the population and infrastructure. Understanding and preparing for these climate hazards is crucial to ensuring the resilience and sustainability of Douala as it navigates these foreseeable changes.
Hazard Outlook
How will Douala's projected climate hazards compare to other cities under a 3.0°C future warming scenario?
Maximum Rainfall
Douala's projected maximum rainfall of 18 mm is among the highest of all cities globally.
Heavy Rainfall Days
With 12 days of heavy rainfall expected, Douala ranks among the highest of all cities for extreme precipitation events.
Elevation
