The Water-Energy-Food (WEF) nexus has emerged as a multi-centric lens for assessing integrated resources management and sustainable development in the past decade. This paper initially reviews the current status of this approach, which has received some critique for being largely conceptual. The call to operationalise the nexus is heralded in many recent publications and a common theme is that ‘nexus thinking’ must evolve into ‘nexus doing’.

To this end, this paper seeks to present opportunities to enable and achieve ‘nexus doing’ through a synthesis of approaches proposed in both contemporary academic journal articles and grey literature. Our synthesis shows that there is a good basis to move forward to implementation and that in places, this has actually started. Nexus policies are being enabled at different spatial extents from regional and national scales to a city level, and appropriate mechanisms and decision support tools to achieve integrated nexus planning are evolving. However, there is no single method that fits all situations; rather the approach must be tailored for each unique situation.

在过去十年中，水-能源-食品（WEF）关系已成为评估综合资源管理和可持续发展的多中心镜头。本文首先回顾了这种方法的当前状态，该方法由于在很大程度上是概念性的而受到了一些批评。在最近的许多出版物中都提出了使神经网络运作的呼吁，一个共同的主题是“神经网络思维”必须演变为“神经网络做事”。

为此，本文试图通过综合在当代学术期刊文章和灰色文献中提出的方法，提出实现和实现“联系做”的机会。我们的综合表明，有很好的基础可以进行实施，而且实际上已经开始。从区域和国家规模到城市级别，在不同的空间范围内都启用了Nexus政策，并且正在实现用于实现集成关系规划的适当机制和决策支持工具。但是，没有一种适合所有情况的方法。而是必须针对每种独特情况量身定制方法。
