The UN food agency warned on Monday that volatility in global food prices were here to stay at a ministerial meeting in Rome on the issue. Farm ministers from 30 countries met at the UN Food and Agriculture Organization (FAO) in Rome for their second meeting. FAO chief Jose Graziano Silva said that prices are expected to remain volatile over the next years. He added that international prices have declined but they are still above their historical levels. He said FAO members should take advantage of the relative calm and prepare for future market turbulence to address food price volatility.
