High fertilizer prices could put an additional 100 million people at risk of undernourishment, a study suggests.

The war in Ukraine has led to the blockade of millions of tons of wheat, barley and corn, but reduced food exports from the region are less of a driver of food price rises than feared, researchers say.

Instead, a modeling study led by University of Edinburgh researchers suggests surging energy and fertilizer prices will have by far the greatest impact on food security in coming decades.
