The joint scenario building initiative �Tomorrow�s world on migration and mobility� of Friedrich-Ebert-Stiftung, Global Future and the International Organization for Migration is premised on the acknowledgement that migration in and of itself is determined by a number of variables and decisions and hence needs to be addressed as the outcome of the combination of various factors. A team of 50 professionals were brought together to consider uncertainty as a central element in their group iterations on plausible migration futures by 2030. The four scenarios presented here are deemed to be plausible by the scenario building team. Their stories provide an opportunity to assess policies, plans and strategies under any scenario for policy makers and practitioners alike.
