当前最令人兴奋的两种水和城市方法是城市新陈代谢和水足迹分析。在此,我将仅就前者发表意见。根据联合国人口局的数据,地球上的城市人口首次超过了农村人口。事实上,目前几乎所有的全球人口增长都发生在城市地区,而农村人口保持不变,甚至有所下降。
Two of the most exciting current approaches to water and cities are urban metabolism and water footprint analyses. Here I will limit my remarks to the former. For the first time in the existence of our species, the planet's urban population is bigger than its rural one, according to UN Population Bureau. In fact, practically all global population growth these days takes place in urban areas while rural population stays unchanged or even declines.
