Port-au-Prince

Haiti

Port-au-Prince is projected to face significant climate hazards that will exacerbate its vulnerabilities. Frequent heatwaves are expected to impact health and well-being, while prolonged drought conditions will strain water resources and agriculture, heightening food security challenges. The city is also anticipated to experience increased arbovirus transmission risk, potentially overwhelming public health systems. Additionally, the risk of malaria is expected to elevate, posing further health threats to the population. The interplay of these climate risks underscores the urgent necessity for addressing the vulnerabilities Port-au-Prince faces as it confronts a future characterized by these significant threats.
