La última extinción

BONN – Agricultores en toda Africa están actualmente involucrados en una lucha desigual contra una mosca pestilente de la fruta cuyo hogar natural está en Asia. La mosca, detectada por primera vez en 2004 en Mombasa en la costa de Kenia, desde entonces hizo estragos en todo el continente, diezmando los mangos y otros cultivos y devastando subsistencias.

En un esfuerzo por combatir a la mosca, un equipo del renombrado instituto ICIPE en el este de Africa recientemente se dirigió a Sri Lanka en busca de un predador natural. Los investigadores ya han detectado uno que, después de un cuidadoso análisis, fue considerado seguro como para ser lanzado en el contexto de Africa y, aparentemente, con posibilidades de derrotar al invasor inoportuno.

Sin embargo, este trabajo pionero hoy está en suspenso, al igual que las esperanzas de millones de agricultores que aguardan una respuesta efectiva y amigable con el medio ambiente para la crisis. Países de Asia -por cierto, países de todo el mundo en desarrollo- no están exportando sus recursos genéticos, abundantes y económicamente importantes.

    Whither the Multilateral Trading System?

    The global economy today is dominated by three major players – China, the EU, and the US – with roughly equal trading volumes and limited incentive to fight for the rules-based global trading system. 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.
