The study presented below establishes the progress and challenges of a Circular Economy (CE) in agriculture in Ibero-America. To this end, a documentary review was carried out to conceptualise the characteristics of 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 study was carried out, starting from the "Scopus" and "Wos" databases, which facilitates the identification of the frequency of writings, number of publications, topics related to CE, key words, authors, among other criteria that are fundamental for recognising the importance in the academic and business spheres. This study uses different statistical programmes such as R-tool, R-Package, Bibliometrix, VOSviewer and Biblioshiny. The findings show a growing trend towards the analysis of sustainability and CE processes in agriculture.
