One of the most striking aspects of the Global Compact on Safe, Orderly and Regular Migration is the involvement of local authorities in its formulation. Local authorities played a key role in lobbying for the Compact, are mentioned as a key partner in migration management and often take the lead in its implementation. Transnational networks play a key role in this process. In Marrakesh, during the 5th Mayoral Forum on Mobility, Migration and Development mayors from all over the world formed the Mayors Migration Council. The process was partially informed by a Cities of Refuge policy brief on transnational city networks. During her time in Marrakesh, Barbara Oomen teamed up with Aida Grovestins to ask mayors what they consider the added value of ‘Marrakesh’.
