This article interrogates the production of knowledge about migration in a prominent UN instrument, the Global Compact for Migration (GCM). To articulate which worlds of mobility it privileges and delegitimises, we explore the GCM’s approach to ‘safe, orderly and regular’ migration, particularly through its formulation of ‘information provision’ for migrants. The politics of knowledge lies in producing both a conception of ‘safe, orderly and regular’, linked to state frameworks and informed migrants, and its ‘other’ – ‘unsafe, disorderly and irregular’ – which becomes linked to risky migration, ill-informed and unruly migrants. Whilst the GCM’s concern with creating safe pathways for movement is promising, we are critical of how the notion of ‘safe, orderly and regular’ has been produced, in conjunction with related concepts, as a means of migration management which might jeopardise its stated aspiration. It can serve to reinforce harmful processes and structures of illegalisation which rest on entrenched gradations of (il)legitimacy in migration policies, supported by underlying epistemological frameworks. We consider two starting points for re-imagining migration knowledges: firstly, a human rights approach, which remains limited in a number of respects, and, secondly, the fracturing of modern/colonial epistemologies.
