Dimensions and Determinants of Sustainable Public School Catering: A Systematic Literature Review

Public school catering is a key instrument for promoting the sustainability of food systems, yet its analysis remains fragmented. This research proposes an integrated approach to identify the main determinants and dimensions of its sustainability. It highlights the central role of governance, regarded as the keystone of the system, operating through territorial anchoring. A systematic review, conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses method on the basis of 66 studies drawn from Scopus and Web of Science, made it possible to identify four interdependent dimensions: socio-cultural, economic, environmental and governance. The findings indicate that the overall performance of the system depends on the quality of governance, which strengthens territorial anchoring as a lever for sustainable improvement. The study thus proposes an innovative conceptual model and operational guidelines to support public decision-makers in fostering a more resilient and responsible school catering system.
