This book provides an overview of the diverse multidisciplinary field of more-than-human design, offering a philosophical grounding of more-than-human design in posthumanism while putting practical design examples and methods to the forefront. There is an urgent need to radically re-imagine design, as its current processes are contributing to global warming, pollution, deforestation, ocean acidification, ozone layer depletion, loss of biodiversity and species extinction.Given this need, ‘more-than-human design’ has emerged as a perspective that widens our thinking beyond solely human-oriented considerations and needs, such as animals, plants and microbes.The book explores the relationship between sustainability and design, touching on topics such as AI, systems thinking, futures studies and pedagogy, and discusses a range of case study projects that are grounded in more-than-human thinking, demonstrating how this can be incorporated into practice. This easily accessible and theoretically grounded book will provide design researchers and educators an excellent introduction to more-than-human thinking.It will also be of interest to students and scholars studying design more broadly, sustainability, environmental studies and service design, as well as to practicing designers interested in sustainability.
