The FAO/UNEP programme organized, in June 2016, a workshop on "Sustainable Value Chains for Sustainable Food Systems". The sessions of the workshop examined the potential contributions of the organization, functioning and governance of food value chains with respect to the sustainability of food systems. It aimed to better frame the notion of "sustainable value chain". The various interventions approached sustainability by diverse entry points, from environmental to social issues, at very diverse scales, from local markets to globally traded commodities. Most of them show practical solutions and good practices as well as the conditions for their implementation. This publication is a compilation of the papers presented at the workshop, including a summary. It aims to stimulate reflection and exchanges among stakeholders and to facilitate the design of appropriate pathways towards more sustainable food chains, contributing to sustainable food systems.
