The European project DIVINFOOD (funded from European Union’s Horizon 2020 research and innovation programme) aims to develop food chains that value under-utilised agrobiodiversity in order to act against the decline of biodiversity and to meet the growing expectations of consumers for healthy, local products that contribute to sustainable food systems.The project brings together 26 partners from 7 countries (Denmark, France, Hungary, Italy, Portugal, Sweden and Switzerland) and relies on 9 living labs to encourage participatory research. The long-term societal challenge is to structure and stabilise territorial networks for collective management of agrobiodiversity, with a view to an economy of the commons that values the ecosystem services provided by the use of underused species and varieties.
