US special envoy for food security: 'Ukraine's grain is getting to the world's hungry'

However, the US special envoy warned that the current global food crisis was caused by "multiple causal factors", from climate change to Covid-19 to conflict. "This is going to be a crisis that unfolds over several years. It can't easily be solved in one year."

"We have to really understand farming issues, particularly in Africa, and be prepared to address the totality of issues that are involved. It's going to take a comprehensive approach and it's going to have to take our working on multiple fronts," Dr. Fowler added.

The UN estimates that at least 345 million people around the world are a just step away from famine and the crisis is getting worse. Africa remains the continent with the most people struggling to eat.
