The overall objective of the project is to design alternative prospective scenarios for landscape management accounting for both land-use and farming innovative practices that would allow the conciliation of regional targets in terms of socio-economic development and biodiversity conservation under global change constraints. These scenarios will test the effect of European agro-environmental policies (e.g. CAP) on the regional and sub-regional scale. They will be derived from participative approaches, thus accounting for local stakeholders’ knowledge of the region and integrating a diversity of representations and visions. Combining both top-down and bottom-up approaches, our scenarios will finally provide useful biodiversity-oriented decision tools to inform public policies for biodiversity conservation at regional scale.
