This document summarizes the results of an analysis of the impacts of high food, fuel, and fertilizer prices resulting from the Russia-Ukraine war on poverty and food security in 19 countries. Key findings include: - 27 million more people fell into poverty, 22 million more became undernourished, and diets deteriorated for 50 million people across the 19 countries. - Cash transfers were the most cost-effective way to reduce poverty, while fertilizer subsidies best reduced hunger by offsetting declining food availability. - A balanced portfolio of short- and long-term policy responses is needed to address each country's unique impacts, including both immediate relief and lasting agricultural investments.
