Impact of climate disaster, migration and health risk on food security in Africa

Africa is endowed with immense natural wealth and cultural diversity, yet it faces complex challenges characterized by climate disasters, migration, and health risks— all of which significantly impact food security across the continent. This chapter examines the complex interplay between these factors, drawing on data from various institutional and organizational sources. It highlights how climate change, despite Africa's minimal contribution to global emissions, intensifies extreme weather events such as droughts, floods, and storms, which in turn disrupt agricultural systems and threaten food production. With temperatures projected to rise by up to 4 °C by 2100, crop yields could decline by 10 % for every 1 °C increase, further exacerbating food insecurity. Economic pressures, political instability, and environmental degradation drive migration, often forcing people into vulnerable living conditions with limited access to healthcare and heightened exposure to disease. Climate-induced migration increases health risks, including malnutrition and outbreaks, compounding the threats to food systems. The continent's reliance on rain-fed agriculture makes it especially susceptible to these disruptions. In response, this chapter advocates for integrated, multi-sectoral strategies to build resilience, including the promotion of climate-smart agriculture, robust disaster risk reduction frameworks, early warning systems, and community-based adaptation plans. It is essential to strengthen health care systems to address the immediate and long-term health risks associated with climate-induced migration and ensure access to preventive measures and treatments. Empowering local communities to lead adaptation efforts is essential for enhancing resilience and ensuring sustainable development in the face of mounting climate challenges.
