This paper presents the results of a legume-based value chain analysis based on twenty-seven case studies in the H2020 LegValue project and discusses those relating to organic legume-based value chains. The analysis aims to illustrate the diversity of legume-based value chains and to discuss the conditions by which they can successfully meet the growing demand for legumes in the EU. The research is based on a qualitative survey of the value chain stakeholders in the case studies. Regarding organic legume-based value chains, the analysis reveals two types that depend on the stakeholder type at the launch of the value chain, the stakeholder’s primary objective in the chain, and the organic legume species involved. The first value chain type is launched by extension services with an aim of developing the organic production of a single legume species. The second type is launched by a stakeholder (processor or collector) acting further downstream in response to market demand for several legume species. A key success factor for these value chains is the ability of the launcher to ensure close coordination along the chain. To achieve this, several means and tools have been identified: the setting-up of a value chain development project, the implementation of contracting practices, production support programmes (technical assistance, financial support), and market support programmes (information sharing, regulation, facilitators).
