Résumé
Geographical indications (GIs) can be used as tools for the development of sustainable food systems, and stakeholders at local and nternational levels often require economic data relating to the development of GIs, especially in terms of impact. With this in view, FAO has developed a collaboration with experts and Masters/PhD students to analyse the data collected from ten cases around the world. The analysis provides some clear evidence about the economic impact of GIs. This paper synthesizes some results by focusing on three well-differentiated cases.
