Entre protection et ouverture : quels effets de la politique d’usage des sols sur les dynamiques de marché foncier sur le littoral aquitain ?

This article proposes an analysis of actual land use planning policies on coastal Aquitaine, with a focus on the area of Bassin d'Arcachon. We first match zoning changes between 2001 and 2010 with land use changes. New development zones and a rise in protection of "natural" uses are the main observed tendencies. Second, we link theses evolutions to land market dynamics. Time spent between buying and constructing suggests the existence of speculative behaviours. Moreover, we test whether changes in zoning produce externalities that are capitalized in land values. Our results show that potential urbanisation zones generate a price premium, but it is not the case for new "natural" zones.
