Naha

Japan

Naha is projected to face multiple climate hazards that could significantly impact its environment and public health. Heavy rainfall events are expected to increase, resulting in flooding and infrastructure challenges. The city will experience a heightened risk of arbovirus transmission, making it more susceptible to diseases like dengue fever, which can heavily burden public health systems. Additionally, elevated malaria risk compounds the public health concerns, indicating that conditions will become more conducive to disease spread. These interconnected climate challenges highlight the need for robust monitoring and adaptive strategies to address the anticipated health risks and infrastructural stress the city will likely encounter in the future.
