Une brève histoire de l'adaptation : l'évolution conceptuelle au fil des rapports du GIEC (1990-2014).

A brief history of adaptation: conceptual evolution across the IPCC reports (1990-2014). In the past decade, work on the concepts of vulnerability, resilience and adaptation became central in climate change literature. At the same time a growing number of studies have focussed on the influence of cognitive factors on decision-making processes, such as interpreting elusive concepts such as adaptation. Comprehension of adaptation has evolved considerably since its recognition as a response to climate change in the 90s by the Intergovernmental Panel on Climate Change (IPCC). Currently protecting systems from weather events (the "adjustment adaptation" approach) is still the prevailing view in climate policies. Nevertheless, a shift toward a "transformation adaptation" approach is being observed. This position would take better account of the complexity of existing systems and allow reexamining their mechanisms (institutional, technical, financial). This paper aims to analyze conceptual advances on adaptation across the five IPCC reports from 1990 to 2014. This contribution attempts to show that the prominence given to adaptation in the latest report (2014) reflects the cognitive difficulty of conceiving this concept, responds to the growing demand to facilitate its operationalization and confirms its relevance for a better understanding of the underlying complexity of climate change and the global environmental change issue. Pursuing reflection on the adaptation concept should certainly contribute to the emergence of a promising and interdisciplinary field of research. [ABSTRACT FROM AUTHOR]
