指的是一个国家、一个地区或一个人在一定时间内消费的所有产品和服务所需要的水资源数量。荷兰学者阿尔杰恩·胡克斯特拉最早提出这个概念,把它形象地解释为“水在生产和消费过程中踏过的脚印”。在《地球生命力报告》中,首次引用“水足迹”这个概念,包括国家“水足迹”和个人“水足迹”。 Refers to the amount of water needed for all products and services consumed by a country, region or individual within a certain period of time. The Dutch scholar, Aljen Hookestra, first proposed this concept and interpreted it as “the footprints of water in production and consumption.” For the first time in the Earth’s Living Report, the notion of “water footprint” is quoted, including national “water footprint” and personal “water footprint.”
