Abstract The sub-Saharan Africa region has been affected by multifaceted interrelated challenges including climate change risks, environmental degradation, political crises, demographic, and food security. The region is geographically exposed to and heavily depends on heat stress-sensitive livelihood and economy. Unlike drought, flood, and erratic rainfall, the situation and impact of heat stress are not well documented. This paper summarized the impact of heat stress on various sectors of the Sahel region. The result revealed that exposure to heat stress contributed to water, agricultural, food security, health, and economic adverse impacts in sub-Saharan Africa. The study also shows in sub- Saharan Africa especially in semiarid and arid areas the future impact of heat stress in various sectors is expected to be more severe. The changes and impacts of heat stress are not uniform across the region. For instance, East Africa is at higher risk of acquiring concurrent health impacts. West Africa is projected to experience severe impacts on food production. South Africa observes the strongest decrease in precipitation with concurrent risks of drought. Thus, understanding the effect of heat stress on humans and various heat-sensitive sectors should be the focus of researchers. However, given the degree of uncertainty of the models' results and effect of heat stress in the region, it is important to develop adaptive capacities at different ecological settings that enable the region population to adapt to risk factors related to climate change and heat stress.

The Impact

This study investigates the relationship between climate variables such as rainfall amount, temperature, and carbon dioxide (CO2) emission and the triple dimension of food security (availability, accessibility, and utilization) in a panel of 25 sub-Saharan African countries from 1985 to 2018. After testing for cross-sectional dependence, unit root and cointegration, the study estimated the pool mean group (PMG) panel autoregressive distributed lag (ARDL). The empirical outcome revealed that rainfall had a significantly positive effect on food availability, accessibility, and utilization in the long run. In contrast, temperature was harmful to food availability and accessibility and had no impact on food utilization. Lastly, CO2 emission positively impacted food availability and accessibility but did not affect food utilization. The study took a step further by integrating some additional variables and performed the panel fully modified ordinary least squares (FMOLS) and dynamic ordinary least squares (DOLS) regression to ensure the robustness of the preceding PMG results. The control variables yielded meaningful results in most cases, so did the FMOLS and DOLS regression. The Granger causality test was conducted to determine the causal link, if any, among the variables. There was evidence of a short-run causal relationship between food availability and CO2 emission. Food accessibility exhibited a causal association with temperature, whereas food utilization was strongly connected with temperature. CO2 emission was linked to rainfall. Lastly, a bidirectional causal link was found between rainfall and temperature. Recommendations to the national, sub-regional, and regional policymakers are addressed and discussed.

The Impact

Many solutions have been proposed to address food security. We present here a prioritized set of actions achievable within the next 2–10 years. By taking a systems approach we follow the impact pathway backwards starting from the needs and desires of the end-users to eventually define the research agenda that will exactly address those targeted solutions with positive impacts. The following actions emerge as high-priority and achievable in the near future: new research tools to study food systems; dis-aggregated intra-household surveys to reveal within-family inequalities in food access; increased scientific consensus on climate change impacts in sub-Saharan Africa; rapid response measures to address sudden emergencies, such as capturing excess rainfall water; financial tools to enable rapid responses with recovery measures afterwards; consideration of restrictions that excess heat and humidity impose on human productivity; secure land ownership and tenure rights to encourage long-term agricultural investment; mechanization at all stages along the food system.

The Impact

As recently as 2019, international security officials reported that international state sponsors of terrorism, such as ISIL, were moving into Sub-Saharan Africa. The causal links between climate change and conflict, especially in an understudied and misunderstood region such as Sub-Saharan Africa, are often complicated and ill-defined. In reality, climate change does not unilaterally or unconditionally strengthen terrorist organizations and, by extension, civil conflict. The circumstances of climate change impact the trajectory of violent non-state armed groups in Sub-Saharan Africa through three primary mechanisms that intersect and interact with one another: natural resource instability, colonialism, and the intensity of intra-state tensions throughout a particular region. Through these three primary lenses, it is evident that, in Sub-Saharan Africa, the effects of climate change exacerbate conditions that, in turn, provide a unique, fertile environment for violent non-state armed groups to develop and thrive.
