The model is based on a trans-disciplinary approach, and leadership, that involves local communities and stakeholders to establish synergies, to give coherence to the whole process, and to build an exit strategy involving territorial dynamics related to the innovation. The model includes a clear definition of the objects, and the process, that should be transformed, and the specific methodologies to involve local communities and stakeholders, to reach the final target user. The model was applied to develop the project, More Nutritious Potatoes, for scaling up new yellow potatoes varieties with improved agronomic and nutritional attributes.application/pdfenSCALING UPSOCIAL INNOVATIONSPOTATO DECLARED SEED SYSTEMRURAL ENTREPRENEURS NUCLEIFAMILY FARMING COMMUNITY SCHOOLSFOOD SECURITY AND NUTRITIONCOLOMBIAJournal Article (peer-reviewed)
