解决粮食链问题

    哥本哈根--全球粮食体系目前处于混乱之中。四年前,长达三十年之久的粮食价格下降趋势迅速扭转。谷物价格从2004年以来已经翻番还多,其他大多数粮食价格也大幅度上升。再加上无以维系的自然资源管理、气候变化负面影响显现以及化肥和能源价格大幅攀升,我们正面临着自从二十世纪七十年代以来最为严重的全球粮食危机。

    价格大幅上扬反映出几个因素。它们是:主要粮食生产地区气候恶劣、对肉类和奶制品需求快速提高、高油价、粮食库存下降、大量使用粮食商品用于制造生物燃料和未能在农村基础设施、研究和技术以及促进发展中国家农业进步所需要的其他公共条件上予以投入。粮食成本巨幅上升已经在贫穷人口中造成更大的饥荒,降低了非贫穷人口的购买力以及三十多个国家中的因粮食引发的骚乱。

    这里主要的教训是,在科技上投资不足以及政府政策失当导致危机。未来避免这些问题,必须帮助全球的农民和粮食加工厂商生产更多的粮食来满足由于世界人口和收入增加而引起的日益增长的需求。而且,他们必须用更少的土地和水来生产更多的粮食,价格要合理,而且不得破坏自然资源或者恶化气候变化。

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
