一个国际援助组织呼吁对世界粮食系统进行全面检查，称诸如玉米等主要食品粮食的价格将会在未来20年内翻倍。总部设立在伦敦的乐施会星期二发布了一份报告称，世界粮食需求量将在2030年前增长70%，气候变化、粮食产量降低以及能源价格增长都为粮食供应带来压力。该组织说，受影响最大的将是低收入的人群，他们多达80%的收入用来购买食物。
报告建议通过增加粮食储备、结束将粮食作物用作生物燃料以及停止世界粮食市场的投机买卖行为来解决粮食需求问题。报告还呼吁从大规模生产商品粮转型为地方上的小规模种植。
An international aid group is calling for an overhaul of the world’s food system, saying prices for staples such as corn will double in the next 20 years. London-based Oxfam released a report Tuesday saying demand for food is expected to rise 70 percent by 2030, as climate change, lower crop yields and rising energy prices pressure food supplies.
The group says those hardest hit will be the poor, who spend as much as 80 percent of their income on food.The report recommends addressing the problem by boosting food reserves, ending the use of food crops in biofuels, and ending speculation in worldwide food markets.It also calls for a shift away from large-scale commercial food producers to smaller local growers.
