Analyse de la perception et des fonctions des tourbières : l'exemple rhônalpin.

Abstract : Integrating ecosystems' functions into preservation strategies renewed criteria taken into account to consolidate the protection of the wetlands. Natural at first, functions gradually took a social importance through an argument based on the use of ecosystems' ecological roles as far as human societies are concerned. The fact that the peatlands' hydrological roles got a lot of media attention quickly made the notion a success. The peatlands' functions then became as many reasons that justified the protection measures taken for them.
This work will identify and assess the peatlands functions in Rhône-Alpes with two purposes: a cognitive one and a methodological one.
This work will study, at first, all the peatlands'interactions since the 19th century thanks to a geographical approach that defines and liaises the functions at the interface between peatlands and society. The work will give, secondly, a way to assess functions.
Our results show that the peat extraction is what rules their identification and establishes their functions until the
middle of the 20th century. During the second half of the 20th century, the way to perceive peatlands considerably evolved:
The minig deposit becomes a biodiversity reserve with multiple functions reinterpreted through the needs of societies.
Assessing the functions shows first of all that they aren't all of the same type. It then demonstrate that peatlands' do
not evenly fulfil all the functions. These results encourage thus to substitute a more differentiated approach of functions for the general one.
