The UN Food and Agriculture Organization (FAO) says that international food prices have risen for the second time in two months.
The Rome-based agency said several factors were to blame for the rise, including bad weather in major exporting countries.
The FAO says its price index climbed nearly 2 percent in January and another 1 percent in February after a six-month period of steady prices.
At the same time, the agency is forecasting an abundant wheat crop this year, with an estimated global yield of 690 million tons, just short of a record harvest in 2011.
Dwindling food supplies and the rising price of staples in recent years have led to food riots in some countries.
