Climate-induced changes on the hydrology of mediterranean basins: a research concept to reduce uncertainty and quantify risk | Changements induits par le climat sur l'hydrologie des bassins Méditerranéens : un concept de recherche pour réduire les incertitudes et quantifier les risques

anglais. The presented project initiative CLIMB (Climate Induced Changes on the Hydrology of Mediterranean Basins Reducing Uncertainty and Quantifying Risk) has recently signed a Grant Agreement in EC's 7th Framework Program (FP7-ENV.2009.1.1.5.2). In its 4-year design, starting from January 2010, the collaborative project for specific cooperation actions (SICA) dedicated to international partner countries shall analyze ongoing and future climate-induced changes in hydrological budgets and extremes across the Mediterranean and neighboring regions. This is undertaken in study sites located in Sardinia, Northern Italy, Southern France, Tunisia, Turkey, Egypt and the Palestinian-administered area Gaza. The work plan is targeted to selected river or aquifer catchments, where the consortium will employ a combination of novel field monitoring and remote sensing concepts, data assimilation, integrated hydrologic modeling and socioeconomic factor analyses to reduce existing uncertainties in climate change impact analysis. Advanced climate scenario analysis will be employed and available ensembles of regional climate model simulations will be downscaled. This process will provide the drivers for an ensemble of hydro(-geo)logical models with different degrees of complexity in terms of process description and level of integration. The results of hydrological modeling and socio-economic factor analysis will enable the development of a GIS-based Vulnerability and Risk Assessment Tool. This tool will serve as a platform for the dissemination of project results, including communication with and planning for local and regional stakeholders. An important output of the research in the individual study sites will be the development of a set of recommendations for an improved monitoring and modeling strategy for climate change impact assessment. CLIMB is forming a cluster of independent projects with WASSERMed from the Environment and CLICO from Socio-Economic Sciences and Humanities Call of FP7 in 2009 (see Fig. 2). The intention of this clustering is to foster scientific synergy and cooperation between the partner projects to achieve improvements in policy outreach on different spatial scales.

français. Le projet FP7 CLIMB (Climate Induced Changes on the Hydrology of Mediterranean Basins Reducing Uncertainty and Quantifying Risk) (FP7-ENV.2009.1.1.5.2), d'une durée de 4 ans, avec un démarrage en janvier 2010 a pour objectif d'analyser l'impact du changement climatique sur l'hydrologie des bassins Méditerranéens. Des sites d'études en Italie, France (bassin de Thau), Tunisie, Turquie, Egypte et la bande de Gaza seront étudiés. Le consortium va employer des techniques nouvelles de télédétection et de géophysique, d'assimilation de données, de modélisation hydrologique et une analyse de facteurs socio économiques pour réduire les incertitudes dans les modèles et analyser l'impact du changement climatique.
