This book examines how public relations might re-imagine itself as an instrument of sustainable citizenship by exploring alternative models of representing and building relationships with and among marginalised publics that disrupt the standard discourses of public relations. It argues that public relations needs to situate itself in the larger context of citizenship, the values and ethics that inform it and the attitudes and behaviours that characterize it.Interlacing critical public relations with a theoretical fabric woven with strands of postcolonial histories, indigenous studies, feminist studies, and political theory, the book brings out the often-unseen processes of relationship building that nurtures solidarity among historically marginalized publics. The book is illustrated with global cases of public relations as sustainable citizenship in action across three core elements of the earth O air, water, and land. In each of the cases, readers can see how resistance movements, not necessarily aligned with any specific organization or interest group, are seeking to change the status quo of a world increasingly defined by exploitation, overconsumption, sectarianism, and faux nationalism. This challenging book will be of interest to students and scholars of not only public relations but also the broader social and management sciences who are interested in issues of environmental and social justice.
