最后的灭绝

    波恩amp#45;amp#45;全非洲的农民目前正在与一种来自亚洲的致命果蝇进行一场不平等的斗争。这一果蝇最早于2004年在肯尼亚沿海的蒙巴萨被发现。从那时以来,它已经横扫非洲大陆,灭绝了芒果和其他作物,并且破坏了人们的生计。

    为了对付这一果蝇,全球著名的东非ICIPE研究所最近前往斯里兰卡寻找天敌。研究人员现在已经确定了一种天敌。经过认真的筛选,研究人员认为将它释放到非洲的环境之中是安全的,而且有可能制服这一不受欢迎的入侵者。

With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships.
