The FAO Food Price Index, which measures the wholesale price of basic foods within a basket, averaged 231 points last month - its highest level since records began in 1990.

It was up 3.4% from December, the seventh monthly rise for the index.

“We are entering an era of food volatility and disruptions in supplies. This is a very serious business for the world,” Mr. Sheeran told Reuters Insider TV on the sidelines of a UN Conference in London.

Surging food prices have come back into the spotlight after they helped fuel the discontent that toppled Tunisia’s president in January and have spilled over to Egypt and Jordan, raising expectations other countries in the region would secure grain stocks to reassure their populations.
