Act now before Ukraine war plunges millions into malnutrition (Nature)

April 21, 2022


Nature published an article by several authors, including IFPRI senior research fellows Derek Headey, David Laborde, and division director Marie Ruel (MTID). The authors write that as the devastation in Ukraine continues to unfold, many of the warnings about the global food crisis precipitated by the war have focused on the risks of famine and severe food insecurity. Another primary concern is the possibility of severe price increases and disruptions to global systems for food, fertilizer, and fuel, leading to millions more malnourished people in low- and middle-income countries (LMICs). Women and children are particularly affected by the food shortages and high food prices resulting from the war against Ukraine. They are especially vulnerable to malnutrition. Poor diets can lead to infants being physically and cognitively impaired, stunted & underweight. Many of the countries that are most vulnerable to the effects of escalating food and fuel prices are also dealing with conflicts (such as Ethiopia, Afghanistan, Myanmar, and Yemen) and extreme climate events, including the drought that has afflicted East Africa since 2020. Both Ethiopia and Yemen are already facing the risk of famine because of drought and extended conflict. Beyond the immediate problem of food shortages, the current crisis could affect a generation of women and children already vulnerable to malnutrition — with implications for the human capital of communities and nations spanning generations. Now is the time to redouble efforts to ensure that the world’s women and children get the food and nutrition they need.
