Sustainable agrifood supply chains: Bibliometric, network and content analyses

Nowadays the agrifood system requires major transformations aimed at promoting sustainability, reducing waste and stimulating a change toward healthy sustainable diets. The scientific literature on the transition to sustainable food models continues to develop rapidly and there is an urgent need to systematize its knowledge structure and thus make future research more vigorous. Recently, several studies have focused on certain aspects of supply chain, such as traceability or decision-making frameworks, but a systematic review of the role of sustainability within the agrifood supply has never been carried out. Through a bibliometric analysis combined with network and content analyses, the present study is aimed at identifying homogeneous areas in the field of agrifood supply chains, investigating the role of innovation technology in the transition to sustainability. The bibliometric results showed that sustainable agrifood supply chains are experiencing an evolving positive trend and represent a challenging research topic which is capturing the attention of scholars. From the network and overlay visualization of keyword co-occurrences four different research clusters were identified and the blockchain emerged as central topic in the field of food security and safety. The content analysis highlighted greater attention to the environmental pillar, compared to the economic and social pillars of the sustainability paradigm. A lack of studies was also observed on the post-consumption phase of the agrifood supply chain, which could represent a research gap to be fulfilled in the light of circular economy.
