Mobile Borders

This special issue of the Journal of Alpine Research - La Revue de Géographie Alpine focuses on the link between mountains and borders in a context where the very notion of border, traditionally seen as a basis for categorisation and delimitation, is being increasingly called into question by today’s multiple flows of goods, services and people. A number of different trends are at work, producing borders that are more fluid, open or fuzzy. As a result, the spatial expression of the border is increasingly difficult to define, a challenge that we place at the heart of the issues addressed in this special edition of the Journal.
