Kyoto-style deal needed on food

An agreement similar to the Kyoto deal on global warming is needed to protect world food supplies, Environment Secretary Hilary Benn will say.

Mr Benn is to tell the Fabian Society that climate change, rising population and water and oil shortages create a "perfect storm" of problems.

He has set up a UK Council of Food Policy Advisers to look at the issue.

In his lecture in London, Mr Benn will urge quicker global help with crises such as price jumps and shortages.
