Heat & health in African cities

Our work on heat is based in Accra, Ghana and Kigali, Rwanda. Through initial consultation, school-age children and people who work outdoors were identified as two under-researched groups particularly vulnerable to increased heat.

Working in the heat

Heat exposure among outdoor workers has become an urgent occupational-health concern in sub-Saharan Africa where livelihoods in markets and construction sites depend on outdoor labour.

In Ghana and Rwanda, outdoor workers are often low-income, low-skilled workers with limited formal education. Many workers, as well as the systems that support them, have limited awareness of how climate change and extreme heat intersect with occupational safety.


Market traders account for about 45.6% of Accra’s informal economy. Despite their contribution to society, markets are often poorly constructed, exposing traders and patrons to extreme heat stress, congestion and poor water and sanitation.

Rapid urbanisation in Kigali has exposed construction workers to environmental hazards including heat stress. Conducting physically demanding labour outdoors makes workers vulnerable to dehydration, heat exhaustion, fatigue, and in severe cases, heatstroke.
