掌握我们的城市未来

纽约——截止本世纪末,地球上的居民将超过百亿,其中85亿将在城市中生活。这或许会成为一场噩梦。但如果拥有足够的政治意愿、远见和创造力——再加上某些简单实用的政策改革——我们或许可以创造梦想中的城市。

城市是经济和社会权力的中心,通过将技能、思想和资源集中到一点推动各国和全球发展。但城市的快速发展往往也伴随着沉重的代价。城市扩张的同时大肆兼并土地,而这些土地本可以被用于粮食生产。城市榨干供水能力,占全球能源使用量的70%,排放的温室气体也占70%以上

要想实现公平可持续的全球增长,我们需要改变城市化快速发展和资源无情消耗造成的不平衡局面。这是联合国可持续发展大会的主要目标,会议已经就未来几十年经济增长将为基础设施(特别是交通运输)、住房、废物处理(尤其是有害物质)和能源供应带来的前所未有的压力做出了警告。

    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.

    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.
