Route-based approaches promise a paradigm shift in international refugee and migration policy. Rather than treating individual country contexts in isolation, they shift attention to developments along key migration corridors. The analytical value is obvious, given the complex and transnational character of mobility dynamics. Yet the growing popularity of route-based approaches also follows a political rationale – they resonate across different political camps, offer operational synergies and may help allocate scarce resources more effectively. At the same time, the concept reflects a fundamental tension in international migration policy: route-based approaches can improve protection along migration corridors, but they can also legitimise the outsourcing of migration control to countries of origin and transit. Whether route-based approaches amount to substantive change or merely repackage a logic of control will depend on how they are implemented.
