综述的目的本综述的目的是讨论在水、能源和食品关联分析中使用模型的挑战。最近的发现水、能源和食品(WEF)关联分析相对较新。建模系统还在不断发展,在执行高质量分析时会遇到一些挑战。我们将讨论其中的许多内容。摘要Nexus建模必须表示和描述世界经济论坛系统之间的复杂相互关系。建模是必要的,因为纽带方法是将视角拓宽到未探索的水平。Nexus分析系统必须考虑不同地点和时间不同的情况,同时集成一系列解决各种组件的模型。在代表一个适当的地理区域的同时,包括使用/生产活动的相关世界经济论坛,以及以支持决策的方式不同的、特定情况的组成部分相互关系,出现了挑战。考虑到不确定性和人口的演变以及生物物理、社会经济、经济和气候因素随着时间的变化而发生的变化,进一步加剧了挑战。此外,当人们需要描述以前没有实施的战略时,就会出现挑战,这些战略既包括现在的战略,也包括气候变化、人口增长和其他相互作用的力量所代表的不确定的未来。需要进行全面的研究来应对这些挑战,并显示世界经济论坛关联性分析的价值。本文讨论了在考虑如何执行信息丰富且准确的世界经济论坛关联分析时出现的与建模相关的挑战。
Purpose of ReviewThe purpose of this review was to discuss challenges regarding model use in water energy food nexus analysis.Recent FindingsWater, energy, and food (WEF) nexus analysis endeavors are relatively new. Modeling systems are just evolving and there are challenges that arise in performing high-quality analysis. We discuss many of these.SummaryNexus modeling must represent and describe complex interrelationships among WEF systems. Modeling is a necessity as the nexus approach is about widening perspectives to unexplored levels. Nexus analysis systems must consider situations that vary from place to place and over time while integrating a family of models that address various components. Challenges arise in representing an appropriate geographic region while encompassing the relevant WEF using/producing activities along with heterogeneous, situation-specific, component interrelationships in a manner that supports decisions. Accounting for uncertainty and the evolution of population along with changes in biophysical, socioeconomic, economic, and climatic elements over time further compounds the challenge. In addition, challenges arise when one needs to describe previously unimplemented strategies both now and into an uncertain future represented by climate change, population growth, and other interacting forces. Comprehensive studies are needed to address these challenges and show the value of WEF nexus analysis. This paper addresses modeling-related challenges that arise when considering how to perform informative and accurate WEF nexus analyses.
