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.

水-能源-粮食关系的综合分析模型：南非案例研究


摘要 跨部门资源管理与全面采用水-能源-粮食（WEF）关系之间缺失的环节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 WEF 关系可持续性指标，并据此开发了一个分析模型，利用层次分析法 (AHP) 以综合方式管理 WEF 资源。该模型以南非为案例研究，建立了世界经济论坛各部门之间的定量关系，简化了资源之间错综复杂的相互联系。蜘蛛图用于说明与其他部门相关的绩效，这些部门的管理被视为可持续或不可持续。该模型随后被应用于评估南非实现可持续发展目标的进展情况。 2015 年和 2018 年估计的综合指数分别为 0.155 和 0.203，将南非的资源管理归类为勉强可持续。该模型是一种决策支持工具，突出了干预的优先领域。
