Land-use planning is at the centre of public debates in Switzerland. It invokes two distinct objectives. One is to achieve an appropriate occupation of the territory; the other is to ensure a sound and moderate use of the land. However, adequate control of territorial development is challenging in the current governance framework. Land crop rotation areas (LCRA) or surfaces d’assolement are currently a tool for land-use planning. The concept aims at preserving the best arable land to ensure food self-sufficiency in the event of border closure, and has been implemented since 1945. Recent work argue that LCRA do not preserve the most valuable land from an environmental and biodiversity perspective. The priority given to LCRA over other ecosystems is questioned considering the existing demographic pressure and increasing environmental strain. The concept of ecosystem services (ES) opens a new perspective for landscape planning, which seeks to reconcile competing land-uses. The aim of this research is to understand the future of rural areas in Switzerland with respect to ecosystem services.
