The Reintegrate project will combine the fields of reintegration and migration governance to establish a new sub-field of reintegration governance (RG). This project will develop a conceptual understanding of what is reintegration governance, its implementation and effectiveness and a new theoretical framework of how different forms of reintegration governance shape returnees reintegration outcomes across an in-depth comparative analysis of four different states: Nepal, Nigeria, the Philippines and Serbia. The project is rooted in the nexus between policies and migrants agency by using a trajectories approach to illustrate the role that returnees play in their own reintegration outcomes. The project makes several original contributions. First, this will be the first study that examines how reintegration is governed and will take a global approach to compare different regimes of RG. Second, the project uses an original analytical and empirical approach to compare RG across four case study countries that are each selected to represent a different form of RG. The reintegrate project will have an impact on migration studies, human geography and political science through the establishment of the new sub-field of reintegration governance.
