Prices for vegetables and staple foods have reached a record highs. Experts have said the recent price hike is because of crop shortages due to widespread droughts and floods.

The London Guardian newspaper reports that over the past six months world wheat and maize prices have risen 57 percent, rice has risen 45 percent and sugar rose 55 percent.

Soybeans have also been at their highest price for the last 16 months and meat prices are at a 20-year high.

Some analysts are concerned the food shortage could lead to rioting in some cities like it did in 2008.

"There is growing concern among countries about continuing volatility and uncertainty in food markets," said Robert Zoellick, president of the World Bank. "These concerns have been compounded by recent increases in grain prices.

"World food price volatility remains significant and in some countries, the volatility is adding to already higher local food prices," he added.

A United Nations spokesman says there's been no effort to improve food management systems in most developing countries.
