BACKGROUND: Africa is undergoing both an environmental and an epidemiological transition. Household air pollution is the predominant form of air pollution, but it is declining, whereas ambient air pollution is increasing. We aimed to quantify how air pollution is affecting health, human capital, and the economy across Africa, with a particular focus on Ethiopia, Ghana, and Rwanda. METHODS: pollution to intelligence quotient (IQ) loss in children younger than 10 years, with use of an exposure-response coefficient based on previously published data. FINDINGS: pollution was estimated to be responsible for 1·96 billion lost IQ points in African children in 2019. INTERPRETATION: Ambient air pollution is increasing across Africa. In the absence of deliberate intervention, it will increase morbidity and mortality, diminish economic productivity, impair human capital formation, and undercut development. Because most African countries are still early in development, they have opportunities to transition rapidly to wind and solar energy, avoiding a reliance on fossil fuel-based economies and minimising pollution. FUNDING: UN Environment Programme.
