Port Harcourt
Nigeria
Port Harcourt is projected to face significant climate hazards that threaten its resilience. Frequent heavy precipitation is expected to lead to more severe flooding, which poses health risks such as increased arbovirus transmission. Concurrently, the city will experience prolonged drought conditions, stressing water resources and affecting agriculture. Further complicating the situation, there is an elevated risk of malaria, as climate changes may expand the conditions suitable for disease transmission. These interconnected climate risks highlight the vulnerabilities of Port Harcourt and the urgent need for strategies to address these challenges. Without documented technology-enabled climate resilience solutions for the city, proactive measures may be needed to manage these impending hazards effectively.
Hazard Outlook
How will Port Harcourt's projected climate hazards compare to other cities under a 3.0°C future warming scenario?
Heavy Rainfall Days
With 12 days of heavy rainfall expected, Port Harcourt ranks among the highest of all cities for extreme precipitation events.
Elevation
At 15 m elevation, Port Harcourt faces high risk from coastal flooding and sea level rise.
Longest Heatwave
Port Harcourt may experience heatwaves lasting up to 5 days, higher than most other cities.
Maximum Rainfall
Port Harcourt's projected maximum rainfall of 11 mm is higher than most cities globally.
Maximum Temperature
Port Harcourt's projected maximum temperature of 9.5°C is near the median of cities globally under a 3.0°C warming scenario.
Exposure Summary
Adaptation Priorities
Port Harcourt faces high exposure to heavy rain, elevation and elevated exposure to heatwave, max rain. These areas may warrant priority attention in adaptation planning.
