The United Nations estimates that world food production will have to increase by seventy percent by twenty-fifty. A world population
growing in number and wealth will require one billion tons more grain each year, and two hundred million tons more meat.
联合国预计,到2050年,世界粮食产量必须增加70%。由于世界人口在数量和财富上不断增加,每年将额外需要10亿吨粮食和2亿吨肉。
The Food and Agriculture Organization says those gains will have to happen largely on existing land through "sustainable intensification."
粮农组织称,这些增产将必须主要在现有的土地上通过“可持续集约化”实现。
Officials say the new report provides the first "global assessment of the state of the planet's land resources."
官员们说这份新报告提供了首份“全球土地资源现状评估”。
