日新月异的城市

城市与我们的未来息息相关。今天,超过一半的世界人口居住在城市,城市的经济发展占全球GDP的85%。

到2030年,在发达国家,我们将达到60%的城市化。城市化整合将更加激烈,预计将有81%的人口居住在城市,这其中大部分将发生在非洲和亚洲。

城市化为智慧生态城市带来巨大机遇的同时,也面临着不同类型城市对基础设施、环境、服务和就业的巨大需求,这将会是巨大的挑战。

城市消耗了世界上四分之三的自然资源。

未来10年,仅纽约、北京、上海和伦敦就需要8万亿美元的基础设施投资。

到2030年,固体废物管理将支配中低收入国家的市政年度预算。

由于人口结构的变化,这个大趋势具有内在的张力。许多城市的人口将持续增长,世界各地每周将有150万人通过移民和生育的方式加入城市。

然而,未来10年,预计将有大约100个顶级城市出现人口萎缩,部分原因是德国、意大利、日本、韩国和中国等国的人口老龄化。亚洲和非洲正在出现新的人口增长中心

那么,我们改如何规划、建设和领导更好的城市呢?

健康城市是指我们在城市生活中所做的一切: 包括我们的工作和我们的社区,我们的自然和人工环境,社会,数字和金融层面。

城市正在发生深刻的变化,从建筑和公用设备的新做法,到交通和物流,从我们如何提供医疗保健,到我们如何共享我们的城市。 它们既需要智能技术和资金流动,也与比法规更加源远流长的艺术的兴盛密不可分。

未来城市化的重点取决于增加机会和改善城市人口的生活质量。
