PARIS – The world has been shaken by unprecedented spikes in food prices, by hunger riots, and by social tensions that demonstrate that food supplies have returned as a source of insecurity – to which global warming and declining natural resources are adding unprecedented urgency. By 2050, it is estimated that there will be nine billion people on earth, so the need for food may double – primarily among urban populations in the world’s poorest countries.
巴黎&#45;&#45;食品价格前所未有地暴涨震撼了世界。因饥饿引发的骚乱以及社会紧张关系表明食品供应再次成为动荡因素，而全球气候变暖以及日益下降的自然资源则给这一空前的紧急局势火上加油。人们估计，到2050年全世界将会有九十亿人口，因此食品需求可能翻番，而这些需求主要来自世界最贫困国家的城市人口。
