This book brings together artieies exploring the design, implementation, man agement, funding, promotion, and evaluation of networked information systems that advocate sustainability and the protection of natural ecosystems. Case stud ies of deployed and planned information systems complement theoretieal work on the methodologieal, technologieal, and organizational foundations of envi ronmental online communieation. Studying communieative strategies and processes that function between disci plines and worldviews, this book helps unearth hidden assumptions and miscon ceptions about environmental issues, contributes to a mutual understanding of existing problems, and suggests priorities for research and policy development. The 25 chapters contained in this volume analyze environmental online commu nieation from four interrelated perspectives: Raising Environmental Awareness, Environmental Science, Corporate Sustainability, and Networks and Virtual Communities. The chapters documentsocial and technologieal challenges and allow readers to appreciate the diversity of approaches and projects. The initiative to compile this edited volume sterns from the activities of the ECOresearch Network [696], an interdisciplinary collaboration that encourages scientific discourse and critieal debate to establish a shared understanding of en vironmental online communieation. The network also hosts the book's official Web site at www.ecoresearch.net/springer [701], whieh provides supplemental material induding text sampies, bibliographie resources, project descriptions, and detailed author profiles induding current affiliations and research interests.
