A new study published in the journal Climate reveals that extreme heat is deepening urban inequality across Africa, with informal settlements being the hardest hit. The research systematically reviewed 21 studies conducted between 2010 and 2024.
The findings link extreme heat to direct illnesses such as dehydration, stroke, and respiratory problems. Indirect impacts include depression, infectious diseases, and increased child mortality, driven by factors like poor housing, overcrowding, and inadequate infrastructure.
The review found evidence from seven countries including South Africa, Kenya, Tanzania, Cameroon, Egypt, Nigeria, and Ghana. Studies examined both direct and indirect health effects, as well as mortality associated with heat exposure. Vulnerability factors include poor housing, limited water access, and socioeconomic disadvantage.
