Mapping Air Quality Risk in Cape Town, South Africa: Implications for Environmental Justice

open access: yesGeoHealth, Volume 10, Issue 4, April 2026.
Abstract Air pollution disproportionately impacts socially vulnerable communities, yet spatial analyzes that integrate social vulnerability and air quality indicators are limited in low‐ and middle‐income countries. This study provided the first comprehensive spatial assessment of air pollution risk in Cape Town, South Africa, combining air quality ...
