Rethinking Agri‐Food Sustainability: A Systematic Bibliometric Literature Review of Circular Economy Approaches to Climate Change Challenges

ABSTRACT The agri‐food sector stands among the foremost drivers of climate change, primarily due to its considerable greenhouse gas emissions and reliance on resource‐intensive processes. Decarbonisation is therefore imperative to mitigate its environmental burden, with particular urgency regarding climate change impacts. Within this framework, the circular economy has gained prominence as a transformative paradigm capable of guiding agri‐food systems towards more sustainable trajectories. By fostering resource efficiency, valorising waste streams, and encouraging regenerative practices, circular strategies hold significant potential to alleviate the sector's climate pressures. Scholarly attention to this nexus has increased substantially, generating a growing corpus of research that examines the capacity of circular economy principles to advance climate change mitigation in agri‐food contexts. However, despite such progress, an overarching synthesis that systematically organises and evaluates these contributions remains absent. This study addresses this gap by conducting a systematic bibliometric review, thereby providing a comprehensive, state‐of‐the‐art assessment of this evolving and impactful research domain.
