提升水可持续性

纽约—2000年,联合国推出了千年发展目标(MDG),自此以后,国际社会正确地把大量注意力放在了提供基本水和卫生服务上。从1990年到2010年,两百多万人获得了改善的水资源。如今,联合国准备以所谓的可持续发展目标(SDG)作为2015年之后MDG的继任者,大规模水基础设施的重要性应该被置于核心位置。

传统智慧认为,改善供水取决于挖井、采取基于社区的解决方案以及集中援助计划覆盖更多人群。但这些重要措施只是更加宏大也更加资本密集的战略的一部分。

据联合国儿童基金会和世界卫生组织的水和卫生服务供应联合监测计划的最新报告,在1990年到2008年期间获得供水的12亿多人中,大部分都获得了接到住处的水管供水。这一数字远大于所谓的“小规模”资源——挖井和雨水收集等——的影响,而有许多人认为后者才是对解决这一问题贡献最大的部分。

    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.
