The Institute of Development Studies is pleased to announce the official launch of the new HeatNexus website — a central platform for sharing the work of nine global research projects focused on heat adaptation and health.
As extreme heat becomes a more common and increasingly deadly threat, the way we adapt will define how we protect lives from what is becoming the defining public health crisis of our time. Funded by the Wellcome Trust, HeatNexus is a pioneering network supporting research in low- and middle-income countries to develop real-world solutions that protect people most at risk.

The newly launched website will be a growing home for:
- Research updates and stories from across the network
- Learning tools, policy briefings, and toolkits
- Event announcements and collaboration opportunities
- Community-driven case studies and resource
Bridging the gap between research and action
At its core, HeatNexus is about bridging the gap between research and action—turning evidence into policies, practices, and scalable interventions that can make a real difference in communities already feeling the impact of a heating world.
This is one of the largest cohorts of researchers in the Global South looking at the evidence on heat adaptation interventions to help protect some of the world’s most vulnerable people.
Nasreen Jessani, IDS HeatNexus Network Support Programme Lead said:
“Our goal is to bring together insights from across the network — to spark meaningful discussion, identify synergies, and explore how this collective knowledge can be amplified beyond the network to drive broader change. Why do research if it’s not about actually improving the lives of people and the planet?”
In this short video, Wellcome’s Head of Capacity and Field Development for Climate and Health, Modi Mwatsama, and Nasreen Jessani, explain the network’s mission, strategy, and global reach.
