Lack of vegetation exacerbates exposure to dangerous heat in dense settlements in a tropical African city by J Van de Walle, O Brousse, L Arnalsteen, C Brimicombe, D Byarugaba, M Demuzere, E Jjemba, S Lwasa, H Misiani, G Nsangi, F Soetewey, H Sseviiri, W Thiery, R Vanhaeren, B F Zaitchik, N P M van Lipzig

“…Normalized Difference Vegetation Index has the highest (75%) power to predict the intra-urban variations in daily mean heat stress, but strong collinearity is found with other variables like impervious surface fraction and population density. Our results have implications for urban planning on the one hand, highlighting the importance of urban greening, and risk management on the other hand, recommending the use of a temperature-humidity index and accounting for large intra-urban heat stress variations and heat-prone districts in urban heat action plans for tropical humid cities.…”
