Warnings of hunger in Jamaica, Nepal, the Philippines and sub-Saharan Africa. Soaring prices for basic foods are beginning to lead to political instability, with governments being forced to step in to artificially control the cost of bread, maize, rice and dairy products. Record world prices for most staple foods have led to 18% food price inflation in China, 13% in Indonesia and Pakistan, and 10% or more in Latin America, Russia and India, according to the UN Food and Agricultural Organisation (FAO). Wheat has doubled in price, maize is nearly 50% higher than a year ago and rice is 20% more expensive, says the UN. Next week the FAO is expected to say that global food reserves are at their lowest in 25 years and that prices will remain high for years.
