Résumé

Established in 2009, the Haut-Vicdessos valley Human and Environment Observatory (OHM, Observatoires Hommes-Milieux) in one of those entities created in France and in the world by the CNRS's INEE (Institut Ecologie et Environnement/ Institute of Ecology and Environment) and pooled together as part of the DRIIHM excellence laboratory, or Labex. Its director, Didier Galop, makes a presentation of this cross-disciplinary observatory whose mission is to observe, document and investigate into ongoing or past transition and adaptation processes in this Ariège high valley and the seven communities it includes. This mountain territory is a place where a mutation which started in the late twentieth century is under way as a result of agricultural and pastoral abandonment and the end of industrial activities giving an end to several thousand years of traditional activities. Now being significantly reforested, the valley's structure is being recomposed while concurrently turning towards the development of tourism.
Marked by rapid and sometimes brutal dynamics, this upper valley represents a life-size field of study for researchers from different disciplines, on which they measure and analyse the past and present influence of human intervention and, more generally, the impact of global change on ecosystems. The data collection operations inherited from past activities (lake sediment and charcoal sampling, peat bog core drilling, etc.) and on site observations establish a dialogue between past, present and future. They highlight the different traces of human appropriation of the Haut-Vicdessos valley and the exploitation of its natural resources, as well as the long-term consequences of conserving this memory of human activities.
