在未来的几年里,随着人口的增长和老龄化,随着生活方式的改变产生了对更多水的需求,随着每户人口的减少,英国水务部门将不得不应对提供充足水服务的挑战。除非采取关键行动,否则到本世纪80年代,英国的每个地区都可能面临供需缺口。改变干旱和洪水频率的极端天气事件和变化增加了这些压力,因此有必要为水管理目的开发基于证据的干旱情景模型。然而,关于家庭对干旱的反应的证据很少,而且很少有研究综合了这些证据。作为回应,本文讨论了在“正常”和干旱条件下驱动生活用水因素的现有实证文献。该论文指出,在“正常”和干旱条件下影响家庭消费的许多不同和不断变化的因素的证据有限,并强调需要在未来需求预测模型中纳入家庭内部和家庭内部因素以及用水做法。然后,论文提出了“水文化”作为一个综合建模框架,将现有的关于社会规范、实践和物质文化相互作用的有限证据结合起来。这使得本文既能捕捉到个人和/或家庭水平变化的不确定性和异质性,也能概述需要解决的研究差距。
In the upcoming years, as the population is growing and ageing, as lifestyle changes create the need for more water and as fewer people live in each household, the UK water sector will have to deal with challenges in the provision of adequate water services. Unless critical action is taken, every area in the UK may face a supply-demand gap by the 2080s. Extreme weather events and variations that alter drought and flood frequency add to these pressures and there is therefore a need to develop evidence-based drought scenarios models for water management purposes. However, little evidence is available about householders’ response to drought and there are few if any studies that have synthesised this evidence. In response, this paper discusses the current empirical literature on the factors driving domestic water consumption under both ‘normal’ and drought conditions. The paper identifies the limited availability of evidence on the many different and evolving factors affecting domestic consumption under both ‘normal’ and drought conditions and stresses the need for the inclusion of inter and intra household factors as well as water use practices in future demand forecasting models. The paper then presents ‘Water Cultures’ as an integrative modelling framework to combine the limited evidence that is available on the interactions of social norms, practices and material cultures. This enables the paper both to capture both the uncertainty and heterogeneity of individual and/or household level variation and also outline the research gaps that need to be addressed.
