Report: Extreme heat in Africa's slums affects sleep, health and work

The report by the International Institute for Environment and Development stated that a growing crisis in overheated cities is affecting the health and livelihoods for more than 1 billion informal settlement dwellers in the Global South. This number will increase sevenfold by 2050.

In a recent statement, IIED's principal researcher Anna Walnycki stated that extreme weather conditions can disrupt productivity and children's education and cause health issues. The climate crisis is affecting people in the poorest countries the most.

IIED, in collaboration with Slum Dwellers international, a global movement for slum-dwellers, conducted a survey of more than 1,000 people living in three informal settlements of Africa to assess the effects of extreme heat.

Researchers found that heat-related workdays were lost by 25% of respondents in Mathare, Kenya, Kombo, Tanzania, and Kariba, Zimbabwe. 40% reported being unable to sleep properly.

Some people reported temperatures inside their homes of up to 40 degrees Celsius.

In all three locations, over a third said that they spent more money during extreme heat to deal with the temperatures. This is roughly one-sixth of their monthly income.

BETTER HEAT DATA

The research showed that unplanned settlements are characterized by a lack of trees and greenery, as well as a high density of buildings constructed from inferior materials. This, in turn, increases the heat levels compared to areas within formal cities.

Wealthier residents can invest in better air conditioning, building materials or move to areas with lower temperatures and more trees.

The International Journal of Environment Research and Public Health published a study that found the poorest residents are the ones who suffer the most from rising temperatures.

The survey was conducted by Mussa Raido who is a researcher for the Centre 'for Community Initiatives, Tanzania.

The report concluded that, despite the fact that research has increased, there are still major gaps regarding the impact of rising temperatures on the urban poor.

The report emphasizes the need for extensive and urgent data collection. It also calls for early heat warning systems and low-cost improvements to buildings that increase ventilation. And it recommends planting trees in high-density areas, which will provide shade and food security.
