人皆有食

伦敦——随着过去十年里食品价格翻了一番,粮食安全问题又重新提上了国际议程。世界怎样才能提高产量再养活10亿人?如何才能提高农业产量?怎样以最佳方式发展水产养殖?

遗憾的是,关注供应并没有意识到问题的全部。全球卡路里产量已经两倍于人类的需求。据测算全球粮食产量的三分之一遭到了浪费。贫困国家损失粮食是因为仓储能力匮乏和供应链衔接不善(比方说缺少冷藏设备);富裕国家供应链也同样浪费粮食,而且消费者也扔掉大量的食物。

此外,许多时候导致饥饿和营养不良的是贫困,而不是市场上粮食匮乏。成百上千万人根本买不起所需的食物,就算供应量增加情况可能也还是这样。最迫切的粮食安全任务是整顿粮食需求,让穷人、特别是最脆弱的母亲和儿童得到有营养的食物。

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
