This contains three reviews of Alexander Betts' Survival Migration: Failed Governance and the Crisis of Displacement by Alexandra Delano, Catherine Weaver and James Milner, respectively, as well as a reply by Alexander Betts. Survival Migration addresses an issue of great and growing importance: the precarious status of refugees who flee their country to survive environmental changes, food insecurity and generalized violence that is, people who seek refuge in another state with the aim of survival. Their status is precarious because they often fall between existing legal categories, and because they often flee to states that are unwilling or unable to protect them. Betts uses the concept of survival migration to highlight this crisis. He introduces another concept regime stretching to show how states adapt, or stretch, existing international frameworks and structures to the situation they face. The analytical and normative advantages of the concepts of survival migration and regime stretching are at the centre of the exchange between Betts and the reviewers of his book.
