人类文明的粮食威胁

帕罗奥图—人类面临着日益严峻、错综复杂的环境问题,既包括气候变化等讨论激烈的挑战,也包括同样甚至更加严峻的微生物生存威胁。微生物提供着诸如作物授粉、农业病虫害控制等关键生态系统功能,支持着我们的生命。我们还面临着其他各种威胁:有毒有机化合物在全世界的传播、流行病爆发,以及矿场资源、水和土壤质量大幅下降和获得难度大幅上升。

资源战争已经来临;如果(比如)印度和巴基斯坦之间爆发“小型”核战争,那么我们知道,这很可能已足以使文明终结。

但我们认为,未来数十年中对全球可持续性最严重的威胁将是一个已经获得了广泛一致的问题:阻止大饥荒变得越来越困难。《2013年世界经济论坛报告》(2013 World Economic Forum Report)指出:“全球粮食和营养安全是重大全球问题,世界必须用越来越少的资源基础养活越来越多的人口,同时必须面临日益波动和不确定的时代。”事实上,该报告指出,超过“如今超过8.7亿的人口吃不饱饭,还有更多人需要面临气候事件和价格飙升风险。”因此,“改善粮食安全”的措施“的需要从未如此紧迫”。

    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.
