Abstract：
The missing link between cross-sectoral resource management and full-scale adoption of the water-energy-food (WEF) nexus has been the lack of analytical tools that provide evidence for policy and decision-making. This study defined WEF nexus sustainability indicators, from where an analytical model was developed to manage WEF resources in an integrated manner using the Analytic Hierarchy Process (AHP). The model established quantitative relationships among WEF sectors, simplifying the intricate interlinkages among resources, using South Africa as a case study. A spider graph was used to illustrate sector performance as related to others, whose management is viewed either as sustainable or unsustainable. The model was then applied to assess progress towards the Sustainable Development Goals in South Africa. The estimated integrated indices of 0.155 and 0.203 for 2015 and 2018, respectively, classify South Africa\'s management of resources as marginally sustainable. The model is a decision support tool that highlights priority areas for intervention.
摘要：
跨部门资源管理与全面采用水-能源-粮食（WEF）关系之间缺失的联系是缺乏为政策和决策提供证据的分析工具。这项研究定义了WEFNexus可持续性指标，从那里开发了一个分析模型，以使用层次分析法（AHP）以集成的方式管理WEF资源。该模型建立了WEF部门之间的定量关系，简化资源之间复杂的相互联系，以南非为例。蜘蛛图用于说明与其他扇区相关的扇区性能，其管理被视为可持续或不可持续。然后，该模型用于评估南非实现可持续发展目标的进展。2015年和2018年的估计综合指数分别为0.155和0.203，将南非的资源管理归类为边际可持续。该模型是一个决策支持工具，突出了干预的优先领域。
