Appropriation et mise en oeuvre de la Trame verte et bleue aux échelles infrarégionales en Région Midi-Pyrénées (Sud-Ouest de la France)

Abstract : The purpose of the Green and Blue Corridor (so called TVB) public policy, laid down in France at the “Grenelle de l’Environment” and established in 2007, is to contribute to the preservation of biodiversity by enhancing and/or restoring ecological continuity beyond the protected areas, in spaces of common biodiversity including rural, suburban and urban areas. This work questions the appropriation of TVB by local stakeholders and the consequences of its implementation in structuring territories. Our approach is based on qualitative surveys conducted together with territorial authorities, local elected officials, farmers and private individuals, in three zones of the southern Midi-Pyrénées Region. It has been shown that national TVB scheme, supported by an homogeneous and very institutionalized frame at national and regional levels comes in a range of adaptive situations in the territories. Moreover the construction process of TVB at the local scales remains confined to political and technical spheres of State and local authorities: local stakeholders, elected but mostly individuals (farmers and private people) are not very involved. Nevertheless these stakeholders are interested by the biodiversity matter, less through political or scientific discourses than in links with their own experience of biodiversity. Furthermore convergent aims (landscape, socio-economy and ecology) around TVB can facilitate its local setting up, because from spite of their diversity stakeholders share common action concerns, even if it is for different reasons. Finally, the study highlights the interest of knowing and considering motivations and constraints of local stakeholders in the TVB implementation plans, in order to root and perpetuate the TVB at the local level of the territories.
