生物燃料时代的粮食

罗马—过去几年来,生物燃料成了争论的焦点。一些人认为,来自有机物的可再生能源资源如同对抗气候变化的魔法棒。但其他人把生物燃料当成生存威胁,因为用于生产它们的农地和水本来可以用于种植粮食。

但这是错误的两分法。不存在粮食和燃料之间的选择。我们可以鱼和熊掌兼得。只要有正确的条件,生物燃料可以为贫困农民提供可持续的廉价能源资源,从而成为增进粮食安全的有效办法。

在一些非洲内陆国家,汽油成本是全球平均水平的三倍,这导致燃料价格成为农业增长的主要瓶颈。扩大生物燃料在这些地区的使用能够提振生产率、创造新的就业机会,特别是在农村地区。如果生物燃料所带来的原料需求增加可以通过家庭农庄和小规模生产商满足,效果将会更好。

    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.

    Rage Against the Elites

    • With the advantage of hindsight, four recent books bring to bear diverse perspectives on the West’s current populist moment. 
    • Taken together, they help us to understand what that moment is and how it arrived, while reminding us that history is contingent, not inevitable

    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.
