The contributors to this volume explore the communication practices of various stakeholders—interested citizens, grassroots and public interest groups, industry representatives, scientists and technical experts, government agencies, federal regulators—engaged in a variety of environmental decision-making contexts in the U.S. and elsewhere. Included are case studies that analyze individuals and organizations participating both within institutional mechanisms and through alternative forms of environmental advocacy. These studies reveal that public participation in environmental decision making is both shaped by and, in many cases, constrained by the ways in which environmental issues, problems, and solutions are defined or framed through the strategic communication practices of the participants.
