The transnational paradigm is now a dominant approach in migration studies. This approach is rooted in the belief that the dense mobility of migrants has created social fields that differ significantly from the sedentary societies bounded by state borders. From the 1980s, transnational practices of migrants have been perceived as challenging integration dynamics and boundary construction. The analysis of development projects carried out by Moroccan migrants for the benefit of their home villages tells a very different story. This case study exemplifies the fact that transnationalism is rooted in migrant/non-migrant relationships. Moroccan transnational development networks are shaped not only by the expectations of the home villages but also by the co-funding policies implemented by different stakeholders. The case of the French co-development policy is examined here.
