Today, one in every seven of the acutely food insecure people in the world lives in Western Africa where hunger has quadrupled in 2022. Even before the Russia-Ukraine conflict, people in the region were facing a perfect storm of the four “Cs” - climate change, conflict, COVID-19 and the rising cost of food and fuel, pushing millions of the poorest and most vulnerable toward food and nutrition insecurity. One of the most immediate additional impacts of the conflict in Ukraine is on food production. West Africa is facing a major and unprecedented fertilizer deficit (1.2-1.5m tons, equivalent to 10-20m tons of grain), expected to reduce by up to 25 percent agricultural production in 2022 and beyond.
