Évolution d’un commun d’altitude : entre matérialité et immatérialité

Collective management of western Pyrenees summer high pastures (estives), based on transhumant pastoralism, has been studied by several authors as a common. Its future seems closely linked to this changing breeding mode. However, collective management organizations remain and face new valuation issues.Taking into account the material and intangible dimensions of an immaterial common linked with the undivided lands of the Basque mountain of Soule (Pyrénées-Atlantiques), helps to widen its evolution understanding.Indeed, the interweaving of owner communities, the imaginary representation of the territory and the immaterial resource appropriation could make it more difficult to set up self-organization principles and priority customary uses necessary to the common sustainability.
