ABSTRACT
Many terms have recently been coined, and many definitions developed, to refer essentially to individuals displaced by environmental factors. Through a review of this definitional debate, this chapter reveals underlying conceptual issues with the attribution of individual migrants to environmental factors in isolation from other factors. It retraces attempts that have been made to develop other approaches and concepts that would offer greater consistency, in particular scenario-based protection (e.g. disaster-induced migration, development-induced displacement and resettlement) and need-based protection (e.g. survival migration).
