Our prospect for Greater Geneva approaches the urgency of socio-ecological transition through the problematic of land, understood in its manifold expressions—as an ecological structure, as appropriated and regulated territory, and as a symbolic landscape of specific places and identities. The central hypothesis is that the currently asymmetric region should be transformed into more equitable, ecologically balanced and poly-centric city-landscape, in which the built and the unbuilt environments, in all their diversity, are productively interwoven. Herein, a successful trans-border governance will be crucial. We envision a determined effort toward a new deal for socio-eco-logical transition based on the overhaul of the current property and governance arrangements on all levels through the idea of commons: from individualism and rentiership in agriculture, real-estate, trans-port and other urban domains, toward the development and promotion of common and cooperative governance arrangements and models.
