Digital ecologies draws together leading social science and humanities scholars to examine how digital media are reshaping the futures of conservation, environmentalism, and ecological politics. The book offers an overview of the emerging field of interdisciplinary digital ecologies research by mapping key debates and issues in the field, with original empirical chapters exploring how livestreams, sensors, mobile technologies, social media platforms, and software are reconfiguring life in profound ways. The collection traverses contexts ranging from animal exercise apps, to surveillance systems on the high seas, and is organised around the themes of encounters, governance, and assemblages. Digital ecologies also includes an agenda-setting intervention by the book’s editors, and three closing chapter-length provocations by leading scholars in digital geographies, the environmental humanities, and media theory that set out trajectories for future research.
