Some of the world’s most significant problems never hit headlines. One example comes from agriculture. Food riots and hunger make news. But the trend lying behind the matters is rarely talked about. This is the decline in the growth in yields of some of the world’s major crops.A new study by the University of Minnesota and McGill University in Montreal looks at where, and how far, this decline is occurring。
一些世界上最有影响的问题从不上头条新闻。其中一个例子就是农业问题。粮食暴动和饥饿产生新闻，但躺在这些问题背后的趋势却很少被谈及。这是因为一些世界主要农作物产区的产量在下降。蒙特利尔的明尼苏达和麦吉尔大学的一项新研究着眼于研究这种正在发生的下降趋势在哪，还有多远。
The authors take a vast number of data points for the four most important crops: rice, wheat corn and soybeans(大豆). They find that on between 24% and 39% of all harvested areas, the improvement in yields that tood place before the 1980s slowed down in the 1990s and 2000s。
研究人员采集了四个最重要农作物的大量的数据点：大米，小麦、玉米和大豆。他们发现，1980年代以前发生的农作物产量从24%上升至39%，在1990年代至2000年代慢慢降低了。
There are two worrying features of the slowdown. One is that it has been particularly sharp in the world’s most populous(人口多的) countries, India and China. Their ability to feed themlves has been an important source of relative stability both within the countries and on world food markets. That lf-sufficiency cannot be taken for granted if yields continue to slow down or rever。
这种放缓有两个令人担忧的特征。其中之一是，它在世界上人口最多的（人口多的）国家，印度和中国，尤为严重。他们养活自己的能力已经成为各国和世界粮食市场相对稳定的一个重要来源。如果收成继续减缓，那么自给自足就不能被认为是想当然的了。茯苓汤
Second, yield growth has been lower in wheat and rice than in corn and soyabeans. This is problematic becau wheat and rice are more important as foods, accounting for around half of all calories consumed. Corn and soyabeans are more important as feed gr
ains. The authors note that “we have preferentially focud our crop improvement efforts on feeding animals and cars rather than on crops that feed people and are the basis of food curity in much of the world。”
第二，小麦和大米的产量增长已经低于玉米和大豆。这是有问题的，因为小麦和大米作为食物更加重要，约占所有消耗热量的一半左右。玉米和大豆更重要的是作为饲料。研究人员指出，“我们更加偏向于在饲养动物和汽车燃料方面提高作物产量，而不是在我们人吃的作物上，而这才是世界上大部分地区粮食安全的基础。
The report qualifies the more optimistic findings of another new paper which suggests that the world will not have to dig up a lot more land for farming in order to feed 9 billion people in 2050, as the Food and Agriculture Organisation has argued。
该研究指出另一项研究的更重要的乐观发现，其中表明，我们将不需要开发更多的土地去喂养2050年时候的90亿人口，正如粮食和农业组织说的一样。
Instead, it says, thanks to slowing population growth, land currently ploughted up for crop
s might be able to revert(回返)to forest or wilderness. This could happen. The trouble is that the forecast assumes continued improvements in yields, which may not actually happen。
相反，它指出，由于人口增长放缓，目前用于耕作农作物的土地也许能够回返为森林或荒野。这有可能发生。而问题在于这一假设是基于农作物产量持续提高的基础上的，这将不太可能真的发生。
