Climate change, biofuels threaten food security - FAO

MILAN/ROME (Reuters) - Climate change bringing floods and drought, growing biofuel demand and national policies to protect domestic markets could drive up global food prices and threaten long-term food security, the United Nations said.

High and volatile food prices are a growing global concern, partly fuelling the protests that toppled the rulers of Tunisia and Egypt this year. The aftershocks have been seen across North Africa and the Middle East from Algeria to Yemen.
