This book presents a novel and systematic social theory of soil, and is representative of the rising interest in 'the material' in social sciences. Bringing together new modes of 'critical description' with speculative practices and methods of inquiry, it contributes to the exploration of current transformations in socioecologies, as well as in political and artistic practices, in order to address global ecological change. The chapters in this edited volume challenge scholars to attend more carefully to the ways in which they think about soil, both materially and theoretically. Contributors address a range of topics, including new ways of thinking about the politics of caring for soils; the ecological and symbiotic relations between soils; how the productive capacities and contested governance of soils are deployed as matters of political concern; and indigenous ways of knowing and being with soil.
