This book provides the rst concerted overview and analysis of social work’s relatively recent engagement with the modern environmental movement. It seeks to extend scholarship in this area beyond hortatory claims of what the profession ought to be doing to address environmental concerns. A recent special issue of the International Journal of Social Welfare (vol 21) was a precursor to the issues developed further in this book and reected the emerging interest in environmental concerns for social work, raising questions about the profession’s responsibility to the non-human world. In this introduction, we review the ecological discourse in social work in order to map the terrain of environmental social work and examine the profession’s response to environmental concerns over the past ten years. While some positive steps have been taken, remaining challenges include a disconnection between the work of environmentalists and environmentally oriented NGOs, and social workers. Thus we attempt to address this important issue by drawing connections between these overlapping areas of practice.
