President Joe Biden is expected to announce how the United States and allies plan to address the global food shortages sparked by the war in Ukraine, according to senior administration officials.

The Black Sea region produces the majority of wheat supplies for Europe, Asia, Africa, and the Middle East, and the U.N. Food and Agriculture Organization’s food price index indicated on April 8 that chaos in Ukraine had caused global prices to rise an unprecedented 13% in March. The data represented the largest jump in food prices since the index was created in 1990. Brian Deese, Biden’s National Economic Council director, previewed the president’s announcement in late March.
