The road to the green transition is paved with planetary, soil, and ground-based developments such as biofuels, geothermal energy, carbon capture and storage, and mineral extraction. These emerging geo-socio-technical potentials engage multiple strata simultaneously and create specific interplays of land, soil, and the underground that sometimes generate unexpected ecological cycles and feedback with the atmosphere, the hydro-system, and the living realm. This book builds on concepts and methods from the humanities and social sciences to explore these emerging geosocial strata in the context of climate change. Inspired by geosocial approaches to the underground and soil new materialisms, as well as a relational approach to Earth strata, it organizes an interdisciplinary inquiry around three key questions: What does it mean to live on a de-stratified Earth? How do earthly re-stratification technologies develop? And which practices and sensitivities toward the Earth emerge from bottom-up experiences?
