Washington DC - World Central Kitchen founder José Andrés warned that President Donald Trump's war of aggression against Iran could potentially trigger a years-long worldwide famine.

The World-famous chef, who founded WCK in 2010 to help provide food relief across much of the world, said that governments around the world should stop focusing exclusively on the oil crisis and start looking at the fertilizer trade.

In an interview with the Guardian on the sidelines of Semafor's global economy conference in Washington DC, Andrés said that a "silent" collapse was occurring due to the war started by the US and Israel.

"I foresee a very big increase in famine across the world by the fall of 2026 and 2027," Andrés said. "It is not only oil that leaves through the strait of Hormuz – it is also heavy, heavy fertilizers."

He warned that yields will likely drop because fertilizers aren't arriving in time for crucial planting windows. If those crops don't get planted at the right time, severe shortages will be experienced after the next harvesting season.

His warnings were echoed by the United Nations Conference on Trade and Development at the end of March, which warned of wide-spread food insecurity.

According to the UNCTAD, it's not just the direct trade of fertilizer which is the issue, but also the sudden drops in natural gas, because it is a key ingredient in many nitrogen-based fertilizers, which are "essential agricultural inputs."

"We can build all the walls we want, but if there are hungry mothers that need to feed their children, there is no wall thick or big enough that is going to stop them," Andrés warned.
