L’application de la DCE dans les départements et régions d’outre-mer : la mise en lumière des discordances entre le concevable et le possible à la Martinique

Abstract : In a context of global environmental change, the issue of water management is aggravated in the French overseas departments. Uncertain knowledge on the context of global change is in contradiction with the concept of “reference conditions” implemented by the European Water Framework Directive (WFD). This context, where uncertainty and risk are intertwined, raises the hypothesis of a possible discrepancy between the obligations set by the WFD and the management options permitted by local conditions. The objective of this paper is to examine the situation in Overseas Departments and their ability to meet the requirements of the WFD. If the implementation of the WFD in the Overseas Departments was followed by major efforts in local consultation and the acquisition of scientific knowledge, the lack of historical scientific data prevents the determination of “reference conditions” as a metastable conception of the ecosystems’ balance. The case of Martinique illustrates the challenges faced by Overseas Departments to ascertain the concept of “reference conditions”, which is difficult to define due to uncertainties of the technical and scientific knowledge. Beyond this issue, the inertia around the implementation of concrete actions is exacerbated in those territories. Cyclical conditions, where uncertainty of knowledge, risk and the precautionary principle interlace, are prone to increase the duration of implementation of collective actions. Relevant institutions in the management of aquatic environments in the Overseas Departments would benefit from using financial instruments that could boost the preservation and improvement of the ecological status of aquatic systems from “reference conditions” defined by the socio-ecological values of the aquatic systems.
