Food chain sustainability concept has significantly escaleted the scientific debate of agricultural economists. This paper attempts to evaluate the problem of governance looking at sustainability in a specific case study about San Marzano Tomato, through the procedure of assessments known as triangulation. The theoretical basis of our work is the priority and responsibility matrix: the study describes phases of the empirical reasearch conducted to assess the sustainability of a typical food supply chain. San Marzano Tomato is endowed with an origin certification label (pdo), meeting demand within high-value market niches. It is a product symbol of Campania region (Italy), benefiting of several interventions of the public regional operator (genetic resources research, support for the establishment of origin certification, etc.). The proposed methodology provides simple rules to follow the time evolution of a food supply chain, judging feasible solutions to satisfy inter-dimensional requisites of durable development. In the proposed case, the driving role of the government appears as a necessary prerequisite to achieving goals of sustainability.
