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。

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.
