Cool Roofs: A Climate Solution for Ahmedabad's Heatwaves

In Ahmedabad, India, a reflective white coating on roofs is part of a global trial to mitigate indoor heat in low-income housing. Led by epidemiologist Aditi Bunker, this initiative aims to improve health and economic outcomes in developing nations, with early results showing reduced temperatures and energy bills.

In the rapidly warming city of Ahmedabad, India, a novel initiative is underway. Hundreds of roofs in informal settlements have been coated with a white reflective paint to tackle extreme heat conditions.

This project, which involves 400 households, is part of a broader scientific effort to study how reducing indoor heat can influence health and economic conditions in developing regions. Spearheaded by Aditi Bunker, an epidemiologist from the University of Heidelberg, the trial is backed by the UK-based Wellcome Trust.

Residents like Nehal Vijaybhai Bhil are already experiencing the benefits, noting cooler indoor temperatures and reduced energy bills. While the study continues in locales like Burkina Faso and Mexico, the initial findings are promising, showing significant temperature reductions within homes.
