Extreme Heat Threatens Health, Jobs, and Food Security in Southern Africa
A recent regional consensus study conducted for the Academy of Science of South Africa highlights extreme heat as a critical and growing threat to health, employment, and food security across southern Africa. Unlike sudden disasters such as floods or storms, extreme heat acts as an insidious integrator hazard, compounding existing vulnerabilities by worsening cardiovascular, respiratory, and renal diseases while reducing crop yields and disrupting outdoor labor. The region, home to over 400 million people within the Southern African Development Community (SADC), has already experienced a temperature rise of 1.0-1.5°C since 1961, with projections indicating a further increase of 4.5-5°C by 2050 under high-emission scenarios. Despite contributing less than 1.3% of global greenhouse gas emissions, southern Africa faces disproportionate impacts. The study emphasizes that heat must be treated as a major public health and development priority rather than merely a weather event. Researchers urge the implementation of practical, evidence-based solutions to mitigate these systemic risks, focusing on adapting health systems, protecting livelihoods, and ensuring food stability in the face of escalating climate challenges.
