Book excerpt: This book introduces an innovative approach to sustainable and regenerative mountain development. Transdisciplinary to biophysical and biocultural scales, it provides answers to the "what, when, how, why, and where" that researchers question on mountains, including the most challenging: So What! Forwarding thinking in its treatment of core subjects, this decolonial, non-hegemonic volume inaugurates the Series with contributions of seasoned montologists, and invites the reader to an engaging excursion to ascend the rugged topography of paradigms, with the scaffolding hike of ambitious curiosity typical of mountain explorers.
