Clean water is essential to human survival, yet it is increasingly scarce. Despite pressures on this crucial resource, people often have little or no opportunity to participate in watershed decisions that affect them, particularly when they live along international watercourses. The success of efforts to manage water effectively, efficiently, and equitably will depend, in large part, on providing the public with a voice in watershed management decisions that affect them. This volume examines experiences in public participation in the management of many watercourses around the world, drawing lessons learned and highlighting areas for further development.
