This book proposes, therefore, a synthesis of the research on geomorphological heritage, both at the conceptual and methodological level. The results presented here are based on numerous studies carried out by various researchers in different contexts (academic research, environmental impact assessment, conservation, geotourism) and countries. They do not aim at giving an exhaustive overview of the geoheritage issues, but we hope that they will be useful for both students and researchers dealing with geomorphosites.
