Extreme Weather, Not Temperature, to Drive Surge in African Malaria Cases by 2050: Study
Extreme Weather, Not Temperature, to Drive Surge in African Malaria Cases by 2050: Study
Climate change is projected to cause over 120 million additional malaria cases and 532,000 extra deaths in Africa by 2050—but not primarily due to rising temperatures, according to a new study published in Nature.
Analyzing 25 years of African data under a mid-range emissions scenario, researchers found that extreme weather events—especially floods and cyclones—are the dominant driver, accounting for 79% of the projected increase.
These disasters disrupt healthcare access, damage infrastructure, and undermine malaria control programs, far more than gradual shifts in temperature suitability for transmission.
The study proposed several strategic shifts necessary to mitigate the climate-driven malaria threat, including:
🟠investing in climate-resilient infrastructure;
🟠enhancing emergency preparedness;
🟠decentralizing health services;
🟠adopting climate-resilient tools;
🟠integrating planning across sectors.
