Le gaspillage de nourriture dans un monde qui a faim

OTTAWA – Un quart de la nourriture produite dans le monde est perdu chaque année à cause de récoltes inefficaces, de mauvaises conditions de stockage et de gaspillage par les ménages. Réduire ce gaspillage de moitié permettrait de nourrir un milliard de personnes de plus – et règlerait une fois pour toute le problème de la faim.

L’ampleur de ce gâchis de nourriture est particulièrement affligeante à la lumière des conclusions d’une nouvelle étude mondiale, L’Étatde l’insécurité alimentaire dans le monde de l’Organisation des Nations unies pour l’alimentation et l’agriculture. Selon la FAO, 57 pays en développement ont échoué à réaliser l’un des Objectifs du Millénaire pour le développement (OMD), arrivé à échéance cette année, qui était de réduire de moitié le nombre de personnes souffrant de la faim. Un individu sur neuf, soit 795 millions au total, se couche le ventre vide.

Bien entendu, des progrès remarquables ont également été enregistrés : au cours du dernier quart de siècle, le monde a nourri deux milliards de personnes de plus et, malgré l’échec de ces 57 pays, le monde en développement dans son ensemble a presque réduit de moitié le nombre de personnes souffrant de la faim. Mais la grande difficulté est de maintenir ces progrès : à l’horizon 2050, la demande alimentaire aura quasiment doublé, d’une part parce qu’il y aura deux milliards de bouches à nourrir en plus et de l’autre à cause de l’appétit croissant d’une classe moyenne émergente.

    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.
