The war in Ukraine has delivered a shock to global energy markets. Now the planet is facing a deeper crisis: a shortage of food.

A crucial portion of the world’s wheat, corn and barley is trapped in Russia and Ukraine because of the war, while an even larger portion of the world’s fertilizers is stuck in Russia and Belarus. The result is that global food and fertilizer prices are soaring. Since the invasion last month, wheat prices have increased by 21%, barley by 33% and some fertilizers by 40%.

The upheaval is compounded by major challenges that were already increasing prices and squeezing supplies, including the pandemic, shipping constraints, high energy costs and recent droughts, floods and fires.
