South Asia is one of the regions most affected by increasing global temperatures and extreme heat events, but more evidence is needed to determine the most appropriate strategies for heat adaptation and harm reduction. Through community participation and pilot testing, this study will assess a possible package of heat-health interventions in representative urban and rural settings in Pakistan. Professor Bhutta and the team will also review global evidence of community-based heat adaptation strategies and use this to evaluate and implement a locally appropriate heat adaptation and reduction plan.
