Résumé
Ensuring adequate food systems while preserving the environment and the farmers’ well-being is one of the greatest challenges of agriculture. We believe that one of the keys of such changes could be based on the promotion of agrobiodiversity, a biocultural object by nature, shaped by 12,000 years of interactions between human societies, plants, and animals. From these interactions, farmers develop and share knowledge about the domesticated landraces and species, and about the wild-associated biodiversity that all sustain agroecosystem functioning. In this session, we invite contributions on case studies or reviews that revealed a diversity of motivations and values, including ones, and their dynamics, between farmers from all contexts and their agricultural landscapes. Local knowledge and practices that are ancestrally inherited, transformed through years of experience, and created de novo by new actors are all welcome, as soon as they are constructed with the same wish, a shared biocultural well-being.This will be a mixed panel with academic presentations and open discussions with the audience. We would like to address together the following questions: (1) What are the main challenges when questioning motivations / values associated to agrobiodiversity?(2) How to reveal the sensitive values?(3) What are the difficulties and interest to conceal small-scale with large-scale analysis?(4) Could we produce a standardized protocol to assess motivations globally?Contributors:Global synthesis of farmers’ values toward crops, Delphine Renard, CNRS, France.Unpacking the multiple motivations of grapevine variety choice, Antoine Doncieux, CEFE, France.Drought-tolerant indigenous crops decline in the face of climate change: A political agroecology account from south-eastern Senegal, Anna Porcuna-Ferrer, CIRAD, France.What role do women play in the circulation of agrobiodiversity?
