绿色和蓝色基础设施（GBI）是解决粮食-水-能源（FWE）关系问题的创新战略。GBI可以提供粮食生产、节能和发电、控制内涝、雨水净化和收集等好处。为衡量性别平等基础设施对家庭妇女和就业关系的影响作出了重大努力。然而，很少有研究来模拟城市地区GBI和FWE之间的多重联系，缺乏统一的方法框架也容易导致对它们之间联系的理解偏差，并使比较结果具有挑战性。本文在已有文献的基础上，阐述了GBI与FWE之间的关系，并对GBI对城市FWE关系的影响进行了定量分析，包括FWE相关效益、生命周期环境影响以及FWE相关效益所避免的上游环境足迹。结果表明，大多数研究集中在FWE相关的好处或（和）的生命周期环境影响的GBI从筒仓的角度来看。研究者对GBI避免的跨境环境足迹关注较少，碳足迹是现有研究中最受关注的问题。关于GBI对城市规模的FWE关系的多重影响的全面量化证据很少。审查概述了模拟GBI和FWE之间联系的方法，并呼吁在城市范围内应用一个整体的方法框架。这种评估做法对于以FWE为导向的城市GBI实施的复原力规划和治理是有意义的。
Green and blue infrastructure (GBI) is an innovative strategy to tackle food-water-energy (FWE) nexus issues. GBI can provide the benefits of food production, energy saving and generation, waterlogging control, rainwater cleansing and harvesting. Significant efforts have been devoted to measuring the implications of GBI on FWE nexus. However, there is little research to simulate the multiple linkages between GBI and FWE nexus in urban areas, and the lack of a unified methodology framework also easily leads to an understanding bias of their connections and makes it challenging to compare the results. Focusing on the prior published literature, this study clarifies the interactions between GBI and FWE nexus and reviews the methods to quantify the implications of GBI on FWE nexus in cities, including FWE-related benefits, life cycle environmental impacts, and avoided upstream environmental footprints induced by FWE-related benefits. It is revealed that most studies focus on the FWE-related benefits or (and) life cycle environmental impacts of GBI from a silo perspective. Researchers pay little attention to the avoided trans-boundary environmental footprints by GBI, and carbon footprint is the greatest concern in the existing research. There is little evidence on comprehensive quantifications regarding multiple impacts of GBI on FWE nexus at the urban scale. The review outlines methods to simulate the linkages between GBI and FWE nexus and calls for a holistic methodological framework to apply at the urban scale. Such assessment practices would make sense for FWE-oriented resilience planning and governance for urban GBI implementation.
