A new study by the Academy of Science of South Africa (SA) has identified extreme heat as one of the fastest-growing threats to health and livelihoods across Southern Africa.
The report, titled “Climate Change and Extreme Heat: Strengthening Resilience and Adaptive Capacity in the Southern African Development Community,” highlights how rising temperatures are placing strain on health systems, food security, labour conditions, urban environments and ecosystems. Experts warn that as climate change intensifies, extreme heat events are becoming more frequent, more severe and more dangerous.
Speaking to Mpho Sithole on Channel Africa, South African Weather Service meteorologist Lehlohonolo Thobela says the increase in extreme heat is primarily driven by rising greenhouse gas concentrations. He explains that heatwaves are now occurring more often, lasting longer and becoming more intense, particularly in arid and semi-arid regions.
Thobela adds that countries such as Namibia and Botswana, as well as western parts of SA and inland regions like Limpopo province and Mpumalanga province, are among the most vulnerable. Urban areas and low-income communities are also at higher risk due to limited heat protection.
He warns that extreme heat reduces crop yields, stresses livestock and threatens food security, while also posing serious health risks, especially to children and the elderly.
Thobela says governments need to strengthen early warning systems, improve urban planning and invest in heat-health action plans. He also stresses the importance of public awareness, encouraging communities to stay hydrated, avoid prolonged sun exposure and protect vulnerable groups.
