Advances and Challenges of a Circular Economy (CE) in Agriculture in Ibero-America: A Bibliometric Perspective

The Circular Economy (CE) is defined as a concept that replaces the end of life of a linear productive process, based on new circular flows of reuse, which also allow for restoration together with renewal in a composite process In this sense, it is considered as one of the key elements to promote the decoupling that arises between economic growth and increasing resource consumption in a new relationship. This study aims to investigate the progress, challenges, opportunities and trends in the Circular Economy (CE) in agriculture in Ibero-America. To this end, a documentary review was carried out to conceptualise the characteristics of the CE and the way in which it has been implemented in Ibero-American countries such as Colombia, Brazil, Chile, Venezuela, Costa Rica, Spain and Portugal. Additionally, a bibliometric analysis was carried out, based on the “Scopus” and “Wos” databases, which facilitates the identification of the frequency of writings, number of publications, topics related to CE, key words and authors, among other fundamental criteria, to recognise the importance in the academic and business spheres. This study uses different statistical programmes such as R-tool 4.3.2, R-Package 4.3.2, Bibliometrix 4.0.0, VOSviewer 1.6.18 and Biblioshiny 4.0.0. The results show a growing trend towards the analysis of sustainability and CE processes in agriculture.
