Design activists, a diverse range of designers, teachers and other actors, are setting new ambitions for design. They fundamentally challenge how, where and when design can catalyze positive impacts to address sustainability. They are also challenging who can utilize the power of the design process. This book provides a rigorous exploration of design activism that will revitalize the design debate and provide a solid platform for students, teachers, design professionals and other practitioners interested in transformative (design) activism. It provides a comprehensive study of contemporary and emergent design activism, collating, synthesizing and analyzing design activist approaches, processes, methods, tools and inspirational examples/outcomes from around the world. Inspired by past design activists and set against the context of global-local tensions, expressions of design activism are mapped. The nature of contemporary design activism is explored, from individual/collective action to the infrastructure that supports it generating powerful participatory design approaches, a diverse toolbox and inspirational outcomes. This is design as a political and social act, design to enable adaptive societal capacity for co-futuring.
