The research project DignityFIRM included a work package on Participatory Action Research (PAR) for migrants working in food supply chain sectors to explore and reflect upon their living and working conditions, and take actions to address the challenges identified by themselves. Coordinated by PICUM, the Platform for Undocumented Migrants, three case studies were conducted in Amsterdam (The Netherlands), Seville (Spain) and Wroclaw (Poland) between 2024 and 2026.
