Towards Sustainable Food Security in the Intergovernmental Authority on Development (IGAD) Region: The Role of Population Dynamics

Résumé

This paper explores how population dynamics influence sustainable food security in the Intergovernmental Authority on Development region, one of Africa’s most rapidly growing demographic zones. The study employs a mixed-methods research design, drawing on secondary data from global and regional databases to analyze demographic trends, labour force changes, urbanization, and nutritional outcomes across eight member states from 2010 to 2020. Results indicate that rapid population growth, youthful age structures, and expanding labour forces have intensified demand for food, employment, and social services. Although declining dependency ratios in several countries suggest emerging opportunities for a demographic dividend, these gains are constrained by unemployment, gender inequality, and limited agricultural modernization. The research also identifies growing urbanization as a key factor reshaping food systems, altering consumption patterns, and increasing pressure on supply chains. Despite some improvements, the prevalence of undernourishment remains high in several countries, reflecting structural vulnerabilities linked to poverty, climate variability, and weak institutional capacity. The findings highlight that demographic change is not inherently detrimental; rather, it can support food security if accompanied by investments in education, youth employment, gender empowerment, and climate-resilient agriculture. The study concludes that sustainable food security in the IGAD region requires integrated demographic and development policies, strengthened regional cooperation, and improved data-driven planning to transform population growth into a catalyst for inclusive and resilient development.
