Food security in the Intergovernmental Authority on Development (IGAD) region of Eastern Africa is affected by a complex interplay of climatic and non-climatic factors. This study explores the major determinants of food security in the region, including extreme climate events (droughts and floods), land use, population growth, food production, market dynamics, and political and economic stability.
The study employed a combination of descriptive and analytical approaches. Climatic data were derived from CHIRPS (1981-2023) to assess drought and flood patterns using the Standardized Precipitation Index (SPI). Non-climatic data, including population statistics, land availability, food production, trade data, and price trends, were sourced from FAOSTAT. The graphical data illustration, correlation analysis was conducted to examine the temporal patterns and relationships between food security determinants and outcomes such as cereal production, food prices, and undernourishment.
Findings reveal that droughts and extreme wet conditions significantly impact food security outcomes across IGAD countries. Rainfall and arable land showed the strongest positive correlation with cereal production. However, despite vast land resources, countries like Sudan and South Sudan have not fully utilized their agricultural potential. Population growth, unbalanced trade policies, and limited investment in agriculture contribute to high food prices and undernutrition. The correlation analysis indicates that economic stability and population dynamics are key influencers of food production and accessibility. Urban-rural population imbalances and policy gaps further exacerbate food insecurity risks.
This study highlights the urgent need for a multi-sectoral and regionally coordinated approach to enhance food security in the IGAD region. Strategies should focus on climate-resilient agriculture, sustainable land management, inclusive economic policies, and food system innovations. Regional cooperation, targeted investments, and context-specific policy interventions are essential to reduce vulnerability and achieve sustainable food security.
东非政府间发展管理局(伊加特)区域的粮食安全受到气候和非气候因素复杂相互作用的影响。本研究探讨了该区域粮食安全的主要决定因素,包括极端气候事件(干旱和洪水)、土地利用、人口增长、粮食生产、市场动态以及政治和经济稳定。
本研究采用了描述性和分析性方法相结合的方式。气候数据来自CHIRPS(1981 - 2023年),使用标准化降水指数(SPI)评估干旱和洪水模式。非气候数据,包括人口统计、土地可利用性、粮食生产、贸易数据和价格趋势,均来自联合国粮食及农业组织统计数据库(FAOSTAT)。通过图形数据展示和相关性分析,研究粮食安全决定因素与谷物产量、粮食价格和营养不良等结果之间的时间模式和关系。
研究结果表明,干旱和极端潮湿状况对伊加特各国的粮食安全结果产生了重大影响。降雨量和耕地与谷物产量呈现出最强的正相关关系。然而,尽管拥有丰富的土地资源,苏丹和南苏丹等国家尚未充分发挥其农业潜力。人口增长、贸易政策失衡以及对农业的投资有限,导致了高粮价和营养不良问题。相关性分析表明,经济稳定和人口动态是粮食生产和可及性的关键影响因素。城乡人口失衡和政策差距进一步加剧了粮食不安全风险。
本研究强调了采取多部门和区域协调方法来加强伊加特区域粮食安全的迫切需求。战略应侧重于气候适应型农业、可持续土地管理、包容性经济政策和粮食系统创新。区域合作、有针对性的投资以及因地制宜的政策干预对于降低脆弱性和实现可持续粮食安全至关重要。
