| Summary: | The wide use of the concept of « Ecosystem services (ES) » imposes a cautious work for delimiting its scope, particularly regarding its effects on nature’s management strategies. The purpose of this paper is to discuss the advantages and limits of the concept when used as framework for hydrosystem management. Within a Foucauldian theoretical framework, and through the study of ES genealogy and the process of its diffusion, we show how ES is transforming from a metaphorical compromise among scientist looking to plead with policy makers for nature’s conservation, to a dispositive. This limits greatly its scope: created to convince mainly international governance actors playing at a global scale, the ES concept does not necessarily have a universal range of action. By analyzing cases on watershed management, we identify at least three uses of the concept: as a tool for raising global awareness; as a mean to foster democratic dialogue facilitator and to support decision; and as a justification for financial nature’s management and/or restoration actions. To date, the actual contribution of the concept is limited and its potential contribution is constrained by technical reasons including the difficulty for evaluating services provided by river ecosystems. Although the educational dimension of the ES concept seems relevant, its usefulness concerning its quantitative characterization and economic valuation needs further discussion. |
