Over the past thirty years, climatic variations as well as water-use changes induced a net decrease in streamflows over the Mediterranean basin. The question arises on climate and human activities evolution trends and on their impacts on water resources. An integrated water resources modeling framework was developed to describe current pressures at the catchment scale, to evaluate changes in water allocation and to apprehend the capacity of adaptation strategies to reduce water tensions. Applied over the Ebro catchment (Spain), the approach enabled identifying areas most vulnerable to climatic and/or anthropogenic pressures.
