Rio +20, sommet crucial pour l'avenir de l'humanité !

NAIROBI – A seulement quelques jours du prochain Sommet de la Terre, Rio +20, on ne sait pas exactement combien de hauts responsables de la planète viendront et à quel type d'accord ils pourraient parvenir sur les principaux sujets qui vont être abordés, à savoir la création d'une "économie verte" et d'un "cadre international pour un développement durable". Ce n'est pas par hasard que ces deux thèmes apparaissent associés.

Le terme d'économie verte a été forgé il y a des années - avant même le premier sommet de la Terre en 1992 - pour examiner dans une nouvelle perspective les liens entre développement durable et économie. L'économie verte bénéficie d'un nouvel élan, car le réchauffement climatique est déjà une réalité, le coût des matières premières augmente et les ressources fondamentales telles que l'air pur, une terre arable et l'eau douce se font de plus en plus rares. De plus en plus d'organismes scientifiques - notamment le PNUE, le Programme des Nations Unies pour l'Environnement, dans son rapport sur l'avenir de l'environnement mondial Global Environment Outlook-5 (GEO-5) - confirment ce qui se dessinait à Rio il y a 20 ans. C'est qui va sortir dans quelques jours. 

Ceux qui ont investi dans un modèle économique et un processus de production datant du 19° ou du 20° siècle s'inquiètent du changement de paradigme. Mais il en est de même de certains segments de la société civile qui craignent que la transition vers une économie verte ne désavantage les pauvres et n'augmente leur exposition aux risques et leur vulnérabilité.

    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.

    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.
