The UN Global Compact for Migration (GCM) is seen as an indicative accomplishment of more than a decade of global deliberations sparked by the United Nations High Level Dialogue on Migration in 2006 and carried forth, by, not least, yearly summits of the intergovernmental Global Forum on Migration and Development since 2007. It is a critical scrutiny of these processes, which is the central concern of the this book, as they have unfolded in a series of different venues taking place in several countries, in the global South as well as the North and across regions of the world. The book focuses on the impact of civil society groups and organizations on these processes concerned with the formulation of an overall normative framework for the governance of migration.
