STIMUL - Scenarios Towards Integrating Multi-scale Land-use tools

Porteurs du projet : Jean-Christophe BUREAU & Raja CHAKIR (Economie Publique)

Autres unités partenaires de BASC : Agronomie, CIRED, ESE, LSCE

Partenaires non académiques : CEPII


Land use and climate change issues are at the intersection of research carried out by teams in the BASC LabEx. BASC teams have developed a range of economic and biophysical models to analyze the factors driving land use change and assess their ecological, agricultural, climatic and economic impacts. These models differ in their methodologies, scale of interest and resolution, but they are very complementary and could provide the LabEx with a unique capacity to analyze policies that influence land use.

The project involves 1) the practical implementation of an interaction between these tools and 2) the use of these combined tools to investigate the effects of three integrated policy scenarios on changes in land use in Europe, and the induced consequences in several dimensions (production, biodiversity, air and water pollution). The analysis of these scenarios will incorporate indirect effects, i.e. those caused by the changes in the global price vector, and the demand/supply responses. For some particular issues (e.g., biodiversity) a finer level of analysis (France) will be also developed as an exploration of downscaling analysis. Overall, STIMUL is a pilot project linking and increasing the consistency of existing tools, with the objective of further integration in the future. The methodological component (compatibility of variables, scales) and the data requirements are central to the project.
