The paper analyses how the Water-Energy-Food Nexus is treated in Computable General Equilibrium (CGE) models, discussing their design, importance and possible ways of improvement. The analysis of their structure is critical for evaluating their potential efficiency in understanding the Nexus, which will be particularly effective for gauging the importance of the topic, the reciprocal dependency of its elements and the expected macroeconomic, demographic and climatic pressures that will act on its components. General equilibrium models can be useful devices to this end, as they are specifically built to track interdependencies and transmission effects across sectors and countries. Nevertheless, the review showed that most CGEs in the literature struggle to represent the competing water uses across sectors and, in particular, those concerning the energy sector. Therefore, it highlights the need to resolve this issue as a necessary step toward improving future research.

本文分析了如何在可计算一般均衡 (CGE) 模型中处理水-能源-食品 Nexus，讨论它们的设计、重要性和可能的​​改进方法。对其结构的分析对于评估它们在理解 Nexus 方面的潜在效率至关重要，这对于衡量该主题的重要性、其要素的相互依赖以及将对其产生影响的预期宏观经济、人口和气候压力特别有效。成分。一般均衡模型可能是为此目的的有用工具，因为它们专门用于跟踪跨部门和国家的相互依存关系和传输效应。然而，审查表明，文献中的大多数 CGE 都难以代表跨部门的竞争用水，特别是，那些与能源部门有关的。因此，它强调需要解决这个问题，作为改进未来研究的必要步骤。
