U.N. and World Bank officials say "the perfect storm" of factors has led to skyrocketing food prices, leading to riots in places in Haiti.

Haitians took to the streets this week, with The Times Online reporting that protesters compared their hunger pangs to the burn of battery acid. U.N. Peacekeepers used rubber bullets in attempt to control the situation.

The riots in Haiti are not the first uprisings over food prices, which have risen 65 percent in the last six years. There have been riots in Burkina Faso, Cameroon, Egypt, Indonesia, Ivory Coast, Mauritania, Mozambique, and Senegal. A survey by the Washington-based International Food Policy Research Institute says staple foods have risen by 80 percent since 2005. The price of rice is at its highest in the last 19 years and wheat is at a 28-year high.

“There is a risk that this unrest will spread in countries where 50 to 60 percent of income goes to food,” FAO Director-General Jacques Diouf told The Times Online. “This is due to higher demand from countries like India and China, where GDP grows at 8-10 percent and the increase in income is going to food.”
