Abstract

The study reviewed the applications of the water-energy-food (WEF) nexus for knowledge generation and decision-making in the Global South. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol identified 336 studies from the Web of Science and Scopus datasets. One hundred eighty-five articles applied WEF nexus tools to improve the understanding of WEF nexus interactions and to show the potential of nexus applications. The other articles (151) focused on nexus applications to guide planning and decision support for resource allocation and policy formulation. Environment, climate, ecosystems, land, and socio-economics were other popular nexus dimensions, while waste and economy were considered to a lesser extent. Limitations associated with nexus applications included unavailability of data, uncertainties from data sources, scale mismatch and bias. The inability of nexus tools to capture the complex realities of WEF interactions is hindering adoption, especially for policy formulations and investment planning. Data limitations could be solved using a sound scientific basis to correct uncertainties and substitute unavailable data. Data gaps can be bridged by engaging stakeholders, who can provide local and indigenous knowledge. Despite the limitations, applying nexus tools could be useful in guiding resource management. Limitations associated with nexus applications included - investment planning. Plausible pathways for operationalising the WEF nexus are discussed.

审查水-能源-粮食关系在全球南部的应用。
这项研究审查了水-能源-粮食关系在全球南方国家知识创造和决策方面的应用。系统评价和荟萃分析方案的首选报告项目从Web of Science和Scopus数据集中确定了336项研究。185篇文章应用了WEF nexus工具来提高对WEF nexus相互作用的理解,并展示了nexus应用程序的潜力。其他文章(151)侧重于nexus应用,以指导资源分配和政策制定的规划和决策支持。环境、气候、生态系统、土地和社会经济是其他受欢迎的联系维度,而废物和经济被考虑的程度较低。与nexus应用相关的限制包括数据不可用、数据源的不确定性、规模不匹配和偏差。关系工具无法捕捉世界经济论坛互动的复杂现实,这阻碍了其应用,尤其是在政策制定和投资规划方面。数据的限制可以通过完善的科学基础来纠正不确定性和替代不可用的数据来解决。数据差距可以通过利益攸关方的参与来弥补,他们可以提供当地和土著知识。尽管存在局限性,应用nexus工具在指导资源管理方面还是很有用的。与nexus应用程序相关的限制包括投资计划。讨论了实现世界经济论坛联系的可行途径。
