Les crises alimentaires résultent de l'interaction complexe des conflits, de la pauvreté, de la variabilité du climat et des chocs économiques, ce qui entraîne une insécurité alimentaire aiguë parmi les populations vulnérables. Selon le dernier Rapport mondial sur les crises alimentaires (2025), le nombre de personnes confrontées à des niveaux graves d'insécurité alimentaire aiguë a triplé au cours de la dernière décennie, passant d'environ 100 millions en 2016 à près de 300 millions de personnes en 2024.  

Le conflit au Soudan perdure depuis avril 2023, et les violences se sont intensifiées en décembre 2023. En février 2024, la crise avait déplacé plus de 7,8 millions de personnes à l'intérieur du pays, et 1,7 million d'autres avaient cherché refuge au-delà des frontières. La violence s'est maintenant étendue à des régions du centre et de l'est du Soudan qui étaient initialement considérées comme des refuges, ce qui a entraîné davantage de déplacements et accru la pression sur les États de l'est du Soudan.

How does food insecurity affect irregular migration, and what role can a needs-based humanitarian response play? A recent collaboration between IFPRI and the World Food Programme took a route-base approach to looking at irregular migration in West Africa—examining migrant origins, their transit experience, and the situation where their journey stalls or ends. The mixed method study includes case studies of the Ténéré desert crossing, across the south-central Sahara, for Malian and Libyan migrants.

One year after Russia invaded Ukraine, the war continues to affect global markets. World stock levels remain tight, and while prices have fallen back to pre-war levels, much uncertainty remains. This seminar will examine how the war has affected global markets, particularly wheat markets. Speakers will discuss the war’s impacts on Ukraine’s producers, wheat buyers and importers in the MENA region, and households in Egypt and Yemen. In addition, the discussion will address export restrictions and sanctions that have exacerbated price levels and volatility.

Join USAID’s Private Sector Engagement Secretariat and USAID’s Rwanda and Bangladesh Missions on Thursday, October 27, 2022, at 9:30 a.m. ET to learn about promising practices for engaging the private sector to advance and sustain inclusive, agriculture-led economic growth and a well-nourished population, especially among women and children.

The world is facing a potential food crisis worse than any seen since World War II. With Russia’s devastating war on Ukraine, a historic drought and heat wave in China, and an irregular monsoon season in South Asia, food supplies from several of the world’s largest granaries are highly uncertain and concerning. Global hunger has been rising since 2015, and the number of people facing acute, crisis-level food insecurity has doubled to well over 200 million. Famine is threatening the lives of large populations in the Horn of Africa, Yemen, and South Sudan.

The conflict in Ukraine is having widespread deleterious impacts on the economies and food systems of many low- and middle-income countries. Rising prices for food, fuel, and fertilizer have raised pressing concerns about food security and poverty. To better understand the risks in specific countries, IFPRI researchers have modeled the impacts of prices of the fuel, fertilizer, and food price shocks on GDP, employment, poverty, hunger, and diet quality in 19 countries in Africa and Asia, and examined the relative cost effectiveness of different policy interventions.
