The analysis of social awareness about water consumption represents an essential tool for water efficiency and decision-making procedures in line with the challenges that emerged by water scarcity. The present study focuses on evaluating the perception of sustainable water consumption (SWC), considering the direct and indirect water consumption through the Water Footprint (WF) indicator and the information about the nexus between urban services and water uses. Based on the norm activation model (NAM) proposed by Schwartz (1977), this research evaluates the perception of the water footprint of different aspects of water consumption and the dependence of this perception on individual water consumption, direct or indirect, and municipal services. The methodology applied to analyse the structural model was the Structural Equation Modelling (SEM). The sample is composed of consumers in the Extremadura region, Spain. The results of the survey show that SWC is influenced by Water Consumption Services (WCS), Indirect domestic Water Consumption (IWC), and Direct domestic Water Consumption (DWC). The model was tested at a confidence level higher than 99.9% with a moderated explanatory capacity (R = 55.7%). Besides, the model indicates the benefit of using WF as an activating tool for decision making highlighted in the NAM considered, in other words, the knowledge about WF influences positively in responsible behaviour with water consumption.
对水资源消耗的社会意识分析是实现水资源效率和决策的重要工具,可满足水资源短缺带来的挑战。本研究侧重于评估可持续水资源消耗(SWC)的感知,同时考虑通过水资源足迹(WF)指标和城市服务与用水关系的信息直接和间接消耗的水资源。本研究基于 Schwartz(1977 年)提出的规范激活模型(NAM),评估了对不同方面水资源消耗的水资源足迹的感知,以及这种感知对个人直接或间接消耗的水资源和市政服务的依赖程度。用于分析结构模型的方法是结构方程模型(SEM)。样本由西班牙埃斯特雷马杜拉地区的消费者组成。调查结果表明,SWC 受到水资源消耗服务(WCS)、间接家庭用水消耗(IWC)和直接家庭用水消耗(DWC)的影响。该模型在置信水平高于 99.9%的情况下进行了测试,解释能力适中(R=55.7%)。此外,该模型表明,使用 WF 作为决策制定的激活工具的好处在考虑的 NAM 中得到了强调,换句话说,对 WF 的了解会对负责任的用水行为产生积极影响。
