Socio-environmental crises are currently transforming the conditions for life on this planet, from climate change, to resource depletion, biodiversity loss and long-term pollutants.The vast scale of these changes, affecting land, sea and air have prompted calls for the ‘ecologicalisation’ of knowledge.This book adopts a much needed ‘more-than-human’ framework to grasp these complexities and challenges.It contains multidisciplinary insights and diverse methodological approaches to question how to revise, reshape and invent methods in order to work with non-humans in participatory ways.The book offers a framework for thinking critically about the promises and potentialities of participation from within a more-than-human paradigm, and opens up trajectories for its future development.It will be of interest to those working in the environmental humanities, animal studies, science and technology studies, ecology, and anthropology.
