Written by two leaders in the field, Public Participation for 21st Century Democracy explores the theory and practice of public participation in decision-making and problem-solving. It examines how public participation developed over time to include myriad thick, thin, and conventional opportunities, occurring in both face-to-face meetings and online settings. The book explores the use of participation in various arenas, including education, health, land use, and state and federal government. It offers a practical framework for thinking about how to engage citizens effectively, and clear explanations of participation scenarios, tactics, and designs. Finally, the book provides a sensible approach for reshaping our participation infrastructure to meet the needs of public officials and citizens.
