In June 2017, KNOMAD brought together a small group of global migration experts to provide a concrete vision for the GCM from a global development perspective. Notes and papers prepared by experts addressed specific policy priorities; examined existing conventions, guidelines, practices, and databases; and identified gaps. They also addressed questions regarding operational architecture: Which actors must be strengthened to take responsibility for safe, orderly, regular, and responsible migration and mobility— and at which levels (global, regional, national, or subnational)? What kind of administrative structure is needed (linked to the question of leadership and lead organization)? What kind of technical capacity building might be needed to achieve safe, orderly, and regular migration and mobility? How can/should institutions and activities be financed? How should commitments under the GCM be monitored? Finally, these notes attempt to explore any overlap between the GCM and the Global Compact on Refugees in the context of mixed flows of refugees and migrants.
