Climate Shocks and Health in Africa's Most Fragile Regions

Africa's Sahel region and the Horn of Africa are facing a perfect storm of climate change, violence, and poor healthcare. A recent review of existing research reveals that these factors are closely linked, with devastating consequences for local communities.

The region's fragile health systems are struggling to cope with the impact of climate variability, including droughts, heatwaves, and extreme weather events. At the same time, communal violence is on the rise, leading to displacement, food insecurity, and a breakdown in healthcare services.

One of the most affected groups is pastoralist communities, who are seeing their livelihoods threatened by climate change. When droughts and heatwaves hit, they struggle to find food and water for their animals, leading to malnutrition and poverty. Women and children are also bearing the brunt of the crisis, with high rates of maternal and child mortality.

Researchers have identified several key pathways through which climate variability, communal violence, and poor health are linked. These include the impact of resource scarcity on communal violence, the effect of drought on food insecurity and child malnutrition, and the consequences of extreme weather events on mental health and healthcare services.

Despite the growing body of research on this topic, there are still significant gaps in our understanding of the issue. For example, there is a lack of longitudinal data, limited mental health surveillance in conflict zones, and under-representation of locally-led research. To address these gaps, researchers are calling for a locally-led, transdisciplinary research agenda that prioritizes primary data collection, mental health surveillance, and longitudinal cohort studies.

The situation is urgent, with climate change and communal violence likely to continue affecting the region for years to come. If left unchecked, the consequences for population health will be severe. However, by working together to address these challenges, it may be possible to build more resilient healthcare systems and support local communities in their time of need.
