Évolutions des réseaux d’acteurs le long de trajectoires de diversification touristique en moyenne montagne : de nouvelles formes de collaborations ?

International audience ; In a context of adaptation to global changes, the mid-mountain territories structured around winter sports tourism are evolving towards more diversified tourism schemes. This process of diversification of the tourism offer can be observed over the long term and alters the trajectories of these territories by enlarging the panel of actors involved in the tourism offer and, thus, by playing on their forms of organisation. Consequently, the stakeholders networks are bound to evolve and we hypothesise that this renewal leads to more collaborations. The article proposes an evolutionary approach to networks and systems of relations between stakeholders in diversification. This approach is formalised by evolving multi-actor diagrams and stakeholders’ maps in two study areas, the Sancy massif, in the Massif Central, and the Haut-Chablais, in the Alps. It is thus possible to affirm that diversification strengthens collaborations by making it necessary to identify pivotal actors, to affirm common visions and objectives, to include the diversity of actors established in the territories, and to articulate spatial relationships, in contexts of a variable dependence on an organisation around winter sports tourism. The analysis carried out in the field allows us to conclude that the Sancy massif, which follows a more advanced process of diversification, is experimenting with more accomplished collaborations, compared to the Haut-Chablais territory which, admittedly, is the table of collaboration by types of diversification stakeholders, but in which an organisation of actors around winter sports persists. ; Dans un contexte d'adaptation aux changements globaux, les territoires de moyenne montagne structurés autour du tourisme des sports d'hiver évoluent vers des schémas touristiques plus diversifiés.
