With the widespread realisation of the significance of climate change, urban communities are increasingly seeking to ensure resilience to future uncertainties in urban water supplies, yet change seems slow with many cities facing ongoing investment in the conventional approach. This is because transforming cities to more sustainable urban water cities, or to Water Sensitive Cities, requires a major overhaul of the hydro-social contract that underpins conventional approaches. This paper provides an overview of the emerging research and practice focused on system resilience and principles of sustainable urban water management Three key pillars that need to underpin the development and practice of a Water Sensitive City are proposed: (i) access to a diversity of water sources underpinned by a diversity of centralised and decentralised infrastructure; (ii) provision of ecosystem services for the built and natural environment; and (iii) socio-political capital for sustainability and water sensitive behaviours. While there is not one example in the world of a Water Sensitive City, there are cities that lead on distinct and varying attributes of the water sensitive approach and examples from Australia and Singapore are presented.
随着气候变化重要性的广泛认知,城市社区越来越寻求确保城市供水对未来不确定性的适应能力,但变化似乎缓慢,许多城市仍在对传统方法进行持续投资。这是因为将城市转变为更具可持续性的城市水系统,或转变为水敏感型城市,需要对支撑传统方法的水文社会契约进行重大改革。本文概述了围绕系统适应能力和可持续城市水管理原则的新兴研究与实践,并提出了支撑水敏感型城市发展与实践的三个关键支柱:(一)通过集中式和分散式基础设施的多样性获取多种水源;(二)为建成环境和自然环境提供生态系统服务;(三)实现可持续性和水敏感行为的社会政治资本。虽然世界上尚无水敏感型城市的范例,但有一些城市在水敏感方法的不同独特属性方面处于领先地位,并列举了澳大利亚和新加坡的例子。
