THE United Nations farm fund head has warned of a global food crisis and said China was an example of how to fight poverty.

Alvaro Lario, head of the International Fund for Agricultural Development, said on Wednesday that climate change, a growing global population and volatile food and energy prices may push millions more vulnerable people into extreme poverty and hunger by 2030.

Speaking at the World Economic Forum in Davos, Switzerland, Mr Lario warned that the ongoing food crisis is likely to continue this year.
