Rettet unsere Böden

BERLIN – Die Vereinten Nationen haben 2015 zum Internationalen Jahr der Böden erklärt, und vom 19. bis 23.April findet die diesjährige weltweite Bodenwoche Global Soil Week statt. Veranstaltungen dieser Art sind zwar nicht gerade glamourös, verdienen aber weitaus mehr Beachtung als sie bekommen.

Intakte Böden sind eine unersetzliche Ressource von unschätzbarem Wert, die mit ihren vielfältigen Funktionen zur Verwirklichung der wichtigsten Entwicklungs- und Umweltziele der internationalen Gemeinschaft beitragen. Boden muss geschützt werden, und zwar dringend.

Gesunde Böden spielen eine entscheidende Rolle bei der Ernährung des Menschen und bei der Bekämpfung des Hungers. Wir sind nicht nur auf sie angewiesen, um Nahrungsmittel zu erzeugen, sondern auch, weil sie neues Trinkwasser schaffen. Sie tragen dazu bei, das Klima der Erde zu regulieren und speichern mehr Kohlenstoff als alle Wälder der Welt zusammen (nur die Ozeane sind ein größerer Kohlenstoffspeicher), und sie sind unverzichtbar für den Erhalt der Biodiversität: In einer Handvoll fruchtbarem Boden leben mehr Mikroorganismen als Menschen auf unserem Planeten. Zwei Drittel aller Arten der Erde leben unter der Erdoberfläche.

    China in the Lead?

    For four decades, China has achieved unprecedented economic growth under a centralized, authoritarian political system, far outpacing growth in the Western liberal democracies. So, is Chinese President Xi Jinping right to double down on authoritarianism, and is the “China model” truly a viable rival to Western-style democratic capitalism?

    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. While parts of the UK are certainly weakening economically, others may finally be overcoming longstanding challenges.

    The UK’s Multilateral Trade Future

    With Brexit looming, the UK has no choice but to redesign its future trading relationships. As a major producer of sophisticated components, its long-term trade strategy should focus on gaining deep and unfettered access to integrated cross-border supply chains – and that means adopting a multilateral approach.
