Mindfulness in sustainability science, practice, and teaching.

This paper explores the current role of mindfulness in sustainability science, practice, and teaching. Based on a qualitative literature review that is complemented by an experimental learning lab, we sketch the patterns and core conceptual trajectories of the mindfulness-sustainability relationship. In addition, we assess this relationship within the field of climate change adaptation and risk reduction.
