Five years after the so-called migration crisis of 2015, researchers evaluate its main impacts on governance: Have the legal and administrative provisions met the challenges? How can we improve to be better prepared for future immigration waves? The presentations will be based on a thorough analysis of the responses with regard to international and European law, but also the situation in Germany. Researchers were part of the Research Initiative on Migration of the Max Planck Society: The Challenges of Migration, Integration and Exclusion.
