It's hard not to notice that gas prices seem to rise by the day. Most drivers may cringe a little more every time they fill up, but they aren't rioting in the streets. This isn't the story in some developing countries, where increasing oil prices — on top of soaring food prices — have increased the potential for widespread hunger.

To cope, the UN World Food Programme has launched an emergency appeal for $500 million. The WFP is the world’s largest humanitarian agency, working in 78 of the world’s poorest countries to help stop hunger. Funded entirely by individual donors and governments, the appeal was written to 60 governments in hopes to reach their goal by May 1. If this amount isn’t reached, the WFP will be forced to cut aid to countries in already desperate situations.

Although the WFP has launched many appeals in the past, this is the first time an appeal has been launched due to a market-generated crisis. The WFP says it was not prepared for the rise in staple food prices such as wheat and corn, as well as fuel.

NPR pointed out this morning that the food-price hikes are exacerbated by a shortage of rice due to bad harvests and growing demand. Rice-exporting countries in Asia are shipping less abroad to have enough of the dietary staple at home.

The UN is preparing plans to ration its food aid to people in need if new donations don't provide more money soon, according to an article in the Financial Times this week. Rising global food prices are putting serious pressures on the World Food Program (WFP)'s budget, to the tune of several million dollars each week.

"The WFP crisis talks come as the body sees the emergence of a "new area of hunger" in developing countries where even middle-class, urban people are being "priced out of the food market" because of rising food prices.

The warning suggests that the price jump in agricultural commodities - such as wheat, corn, rice and soyabeans - is having a wider impact than thought, hitting countries that have previously largely escaped hunger."

It is not just the UN that will have to ration its food aid. Countries like Egypt and Pakistan are reinstating or strengthening rationing systems for the first time in decades. Unfortunately, the crisis will be getting worse in the short term. According to the US Department of Agriculture "high agricultural commodities prices [will] continue for at least the next two to three years."
