April 23/The Scotsman -- The world food crisis has plunged dozens of countries into starvation and sparked riots across the globe.

The price of wheat has risen by 130% in a year, and rice has shot up by 74%. Millions of the world's poorest people are now facing starvation.

Gordon Brown, the U.K. prime minister, has called for international action. Writing on the Downing Street website, he said, "The World Health Organization views hunger as the number-one threat to public health across the world, responsible for a third of child deaths. Tackling hunger is a moral challenge to each of us."

The U.K. government is to provide 30 million pounds ($60 million) to help the 840 million people estimated to be suffering chronic hunger, while the UN Food and Agriculture Organization says the food crisis has hit 36 countries.

Earlier this month, the World Bank announced emergency measures, including a doubling of loans to African farmers.

Economic growth has created a desire for more meat in China and India, so more corn is needed to feed livestock -- again forcing the price up. Meanwhile, the soaring cost of oil has increased the price of food processing and transport. Added to this, climate change is resulting in floods and droughts that are destroying harvests. Last year, Australia suffered its worst drought for over a century.

Downing Street is hosting a meeting involving scientists, supermarkets, farmers and aid agencies. Their aim is to come up with a plan that can be presented to the EU, G8 and UN.
