Mountain territories, and especially upper valleys have been the subject of different economic dynamics since more than two centuries, leading some remote territories to become international resorts or tourist spots. Glaciers are a particularly good example of this evolution: from a mostly negative perception by inhabitants before the XVIIIe century, they became highly attractive places with tourism development. However, current climate change, resulting in a drastic shrinkage of glaciers around the world could transform the value of glaciers. In this context, it seems important to understand how environmental changes can and could transform some tourist territories by influencing their resource. Drawing on a relational and territorial approach of the resource, the aim of this conference paper is to present the processes leading to the construction of glaciers as cultural and economic resources, and how those processes are nowadays put to question and reoriented by the consequences of climate change.
