The Concept of Adaptation

Adaptation (i.e., actions that reduce the harms caused by climate change) is widely recognized as one of two pillars of climate action, along with mitigation (i.e., actions that reduce the concentrations of greenhouse gases which cause climate change). Action to date in both pillars is widely recognized as insufficient. This article argues that a major source of this deficiency of adaptation is ambiguity in the concept of adaptation, which hinders planning and implementation of action. The review traces the origins and consequences of this ambiguity and examines three major conceptual obstacles: the unclear relationship between adaptation and mitigation, the tendency to define adaptation by listing distinct types that are not directly comparable and hence difficult to measure, and a persistent separation of short-term and long-term perspectives that limits the ability to build from current action to transformation. The article identifies recent efforts that have addressed these obstacles, although new areas of concern have emerged, particularly maladaptation and Loss and Damage.
