This report presents the results of participatory action research (PAR) conducted in the 13 MATILDE regions between mid-2021 and early 2022, focusing on TCNs integration paths and on the role of migrants within processes of local development in rural and mountain areas of Europe. In each country, activities took place under the coordination of the Local Case Study Working Group, with full involvement of local stakeholders and good media coverage in most cases. For each of the 13 case studies presented, theauthors introduce the objectives of the local action research, then identify and describe the actors involved (focusing on TCNs), the type of activities actually carried out and the main outcomes achieved, considering also the impact in terms of change eventually produced (e.g., new perceptions and representations about the role of migrants, self-consciousness of TCNs with respect to their contribution to local economies and societies, etc.).
