From Evidence to Action: Mitigating Climate-Induced Thermal Stress in Zimbabwe’s Health Systems

Extreme ambient temperatures pose a severe institutional threat to healthcare delivery, compromise occupational health, and adverse maternal, new-born, and child health (MNCH) outcomes.  In rural Zimbabwe, the Heat Indicators of Global Health (HIGH Horizons) project conducted empirical research across three health facilities, Mount Darwin District Hospital, Dotito Rural Health Centre, and Chitse Rural Health Centre, […]

A burning issue: resources on heat exposure and maternal, newborn, and child health

As global temperatures rise, heat exposure has become an urgent issue for maternal, newborn, and child health (MNCH), especially where temperatures are already high and in resource-limited settings where the infrastructure to reduce heat stress is constrained. Yet health systems have lacked a common way to measure this risk and track progress in addressing it. […]

Co-design in climate adaptation 

The evidence on extreme heat and maternal health is robust, growing and increasingly difficult to ignore, and yet the gap between what that evidence recommends and what pregnant women and new mothers are actually able to do in the face of extreme heat remains one of the most persistent challenges in translating climate health research into real-world impact. Understanding why that gap exists, and how to close it, requires the global health community to look beyond the quality of its science and examine the assumptions embedded in how it designs the tools and systems built from that science.

Science, Policy, and People: Climate-Health Resilience in Africa

Public dialogues on climate change have long been dominated by concerns about carbon emissions, biodiversity loss, and economic disruption. Far less attention has been given to a more immediate consequence: the ways environmental changes are reshaping disease patterns, weakening food systems, and stretching fragile health infrastructures. Climate change has become a structural driver of diseases […]

HIGH Horizons at IMNCH 2026: Evidence to Action on Extreme Heat and MNCH

The International Maternal Newborn Health Conference (IMNHC) 2026 brings together governments, civil society organizations, professional associations, and international partners from the global maternal and newborn health community to assess progress and drive collective action. It will take place from March 23–26, 2026, at The Edge Convention Center, Nairobi, Kenya, and it is one of the […]

Uncoping: Insights from urban heat exposure during and after pregnancy

Pregnant and postpartum women in urban townships face extreme heat every day, hence, increasing health risks for mothers and their babies. The HIGH Horizons Project used Photovoice to capture these lived experiences, revealing how structural barriers make personal coping strategies fall short. These insights are now helping co-develop messages for early warning systems, including the MotherHeat Alert App, highlighting the need for solutions that go beyond individual responsibility to protect those most vulnerable.

Introducing The Conceptual Framework On Extreme Heat And Maternal, Newborn And Child Health

HIGH Horizons, alongside the World Health Organization (WHO), has developed a conceptual framework for extreme heat and maternal, newborn and child health. We spoke with Annie Portela, Department of Maternal, Newborn, Child and Adolescent Health and Ageing at the WHO, about developing the framework, what WHO and HIGH Horizons aim to achieve with it and who […]
