Book excerpt: "The present report delineates Europe's mountain areas according to topography and altitude criteria, based on data from digital elevation models. For the purposes of this study, 36 % of Europe's area is defined as mountainous, including 29 % of the EU27. Massifs also served as a unit of analysis and 15 were defined. This report is based on a highly variable evidence base. For certain variables, comprehensive datasets are only available for EU Member States. Comprehensive Europe-wide datasets are only available for a few variable and topics, often only for one point in time. To help overcome these data gaps, many issues are illustrated through regional, national or sub-national case studies."--Editor.
