 The water–energy–food (WEF) nexus has emerged as a frontier issue in interdisciplinary research and is one of
the most complex sustainability challenges that the world is faced with today. In this review, we ask: (i) how can the inter-
dependent relationships among water, energy, and food resources be identified? (ii) what methods have been applied to
understand these relationships? and (iii) what are the future opportunities and challenges for the WEF nexus development?
To answer these questions, we provide a critical assessment of the relevant literature from Web of Science database on
WEF nexus published between 2008 and 2019 using a bibliometric analysis. Using the resulting 396 published articles, we
systematically reviewed the concept and the bibliometric characteristics of the WEF nexus research to assess the develop-
ment footprint. Based on the most popular topics and research methods found in these publications, we discussed the
major research limitations as well as future opportunities and challenges for WEF research. An examination of internal
and external relationships among topics showed that the three most recent hot areas of WEF nexus research include
(i) water, energy, and food, (ii) policy-making and resource management, and (iii) system models and methods. Specifically,
considering that no one method can solve all problems, we innovatively summarized the application scope and the advan-
tages and disadvantages of each method, with a particular focus on the WEF nexus models. This was undertaken to support
readers in choosing a scientific method to analyze the specific WEF nexus related issues. We anticipate that complex inter-
dependence mechanisms, data uncertainty, analytical model development, and in-depth policy implementation will pose
the greatest challenges for future WEF nexus research; however, these challenges will also generate better research oppor-
tunities. This bibliometric review highlights that to increase understanding of complex WEF systems and formulating opti-
mal strategies to manage them is of great significance for environmental and social sustainability.
