Application of the Circular Economy in Research in the Agri-Food Supply Chain: Bibliometric, Network, and Content Analysis

The agri-food supply chain (AFSC) is vital to ensure global food security. It faces significant environmental and economic challenges, requiring the adoption of circular economy (CE) principles to enhance sustainability and resource efficiency. This article presents a bibliometric analysis of 162 Web of Science (WoS) and Scopus documents from 2017 to 2024, focusing on contributions from leading authors and countries regarding CE application in AFSCs. Using bibliometrix R-Tool Version 4.3.2 and VOSviewer 1.6.20, we identified key topics, such as “Transforming Agriculture through Innovation and Sustainability in the Supply Chain” and “Implementation of a Circular Economy Framework in Agricultural Supply Chains”. We also pinpointed outdated and oversaturated research topics while proposing emerging subjects based on multiple analyses of the scientific literature corpus (title, abstract, and keywords). Finally, the combined bibliometric, network, and content analysis provided a comprehensive “big picture” of CE application in the AFSC, guiding future projects and research.
