This project deals with the analysis of the watershed of the Arc and the study of the bio region. Geographically, this large territory is located in the PACA region, it straddles the department of Var and that of Bouches-du-Rhône. The Arc river collects the flow of water from five large massifs along its route, including the emblematic Sainte-Victoire massif. It has its source at Saint-Maximin-la-Sainte-Baume and flows into the Etang de Berre. This study means precise knowledge of the site by addressing issues of mobility, equipment, biodiversity and natural risks. The bio-region includes the ability of a territory to make the most of its characteristics with the aim of acquiring food, energy and economic autonomy without relying on geographical and administrative limits.

This work is carried out in three steps. First, the analysis with the realization of maps thanks to the recovery of data, then the issues raised by the understanding of the territory. Finally, the strategies and our opinion of the different aspects of the territory complete this work and initiate my graduation project.
