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 and the associated impacts on inadequate water and sanitation.

Working in the heat

Heat exposure among people working outdoors has become an urgent occupational health concern in sub-Saharan Africa and throughout the world.

In Ghana and Rwanda, people working outdoors, including in markets and construction sites are often low-income, low-skilled workers with limited formal education who rely on their labour for their livelihood. Many workers, as well as the systems that support them, have limited options for how they can manage the effects of excessive heat and possible impacts on occupational safety.


Market traders account for nearly half of Accra’s informal economy. Despite their essential contribution to society, markets are often poorly constructed, exposing traders and patrons to excessive heat, overcrowding and poor water and sanitation.

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