La prochaine vague de migrants

MANILLE – Imaginez que vous êtes agriculteur. Vos récoltes se dessèchent à mesure que les modèles météorologiques se dégradent, l'eau de votre puits, trop salée, n'est plus potable et le riz est trop cher pour l'acheter sur le marché. Alors vous déménagez à la recherche d'une vie meilleure.

Des millions de personnes dans des communautés vulnérables à travers le monde n'ont pas imaginé un tel scénario. Elles le vivent en ce moment, à cause des ravages provoqués par un climat de plus en plus imprévisible. Et leur nombre risque d'augmenter à mesure que s'intensifient les effets du changement climatique.

Mais le monde est encore moins préparé à ces futurs migrants du changement climatique que l'Europe l'est à l'actuelle vague de personnes qui fuient le Moyen-Orient et l'Afrique du Nord. La plupart des migrants climatiques seront déplacés à l'intérieur de leurs propres frontières, mais d'autres n'auront pas d'autre choix que de chercher refuge à l'étranger. Si le niveau de la mer monte de plus d'un mètre, l'ensemble de la population de l'atoll du Pacifique et des pays du récif corallien risquent de devoir déménager.

    The Next Battle in China’s War on Corruption

    • Chinese President Xi Jinping knows well the threat that corruption poses to the authority of the Communist Party of China and the state it controls. 
    • But moving beyond Xi's anti-corruption purge to build robust and lasting anti-graft institutions will not be easy, owing to enduring opportunities for bureaucratic capture.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.
