Bissau

Guinea-Bissau

Bissau is projected to face significant climate hazards, including extreme heat, dangerous heat extremes, and frequent heatwaves. These conditions will heighten the risk of heat-related illnesses among the population. In addition, heavy rainfall events will likely cause flooding, while prolonged drought conditions threaten water resources and agriculture. The city will experience elevated risks of arbovirus transmission and malaria, linked to these changing climate patterns. These combined challenges indicate a future where residents are increasingly vulnerable to health risks and environmental impacts, underscoring the urgent need for a comprehensive understanding of these climate challenges to support effective responses.
