ABSTRACT
Crisis migration represents an umbrella term (Martin, Weerasinghe and Taylor 2014, Chapter 1 in this volume). It highlights a range of emerging migration challenges that arise in the context of humanitarian crisis: displacement, including that which falls outside existing protection frameworks (Betts 2013a), trapped or stranded populations (Dowd 2008; Collyer 2010), mixed migration (Van Hear, Brubaker and Bessa 2009; Koser and Martin 2011), and anticipatory movements. Many of these challenges are relatively newly recognized and so do not map neatly onto the mandates of existing international organizations (IOs) or onto the coverage of existing international norms. There is no single, coherent, and unified “crisis migration regime,” for either the overarching concept or its constitutive elements. As the other chapters in this volume highlight, there are therefore significant protection gaps for different groups of vulnerable migrants affected by crisis.
