Circular Economy Transitions in Agri-Food Supply Chains: Integrating Socio-Economic and Environmental Perspectives through Bibliometric and Systematic Analysis
摘要
The agri-food supply chain system is facing significant challenges due to climate change, food waste, and resource scarcity, dominated by a linear supply chain (LSC). Therefore, this research aims to examine the literature on mathematical modeling that drives a paradigm shift from linear economy to closed-loop (CLSC) and circular economy models. A systematic literature review (SLR) and bibliometric analysis of 194 scientific articles from the Scopus database published between 2015 and 2025 are conducted on mathematical modeling and optimization in agri-food supply chains. The analysis classifies articles based on model complexity, optimization approaches, sustainability dimensions, as well as conceptual and methodological contributions. The results show that there is an increasing trend in articles on circular agri-food supply chains, with a predominant focus on environmental and economic aspects, but the social dimension remains relatively underexplored. This research also presents a comprehensive visualization of circular economy-based supply chain from upstream to downstream is also presented with strategic insights relevant to farmers, processors, distributors, and policymakers. This research identifies gaps and proposes future directions that include the integration of social aspects, digital technologies, and community engagement. The result is expected to serve as a strategic guide for strengthening sustainability policies and practices in the agri-food sector, supporting a sustainable circular transition.
