Freetown
Sierra Leone
Freetown is projected to face significant climate hazards, including frequent heatwaves and intense rainfall events that increase flooding risks. Additionally, prolonged drought conditions may result in severe water shortages, impacting agriculture and livelihoods. The city also confronts elevated risks of arbovirus transmission and malaria due to changing environmental conditions, which pose critical public health challenges. As these climate-related events become more common, the city’s vulnerabilities to health and infrastructure challenges intensify. Addressing these hazards is crucial for enhancing resilience to ensure community safety and sustainability in the face of climate change impacts.
