The authors maintain that economic growth that destroys ecological support systems is neither sustainable nor true progress, and suggest that limits on water use set a boundary that makes society more conscious and clear about its choices—which rivers are being protected; which are being degraded; and why. Postel and Richter then advocate principles of the public trust doctrine as a guiding ethic for water resource management and development policy.
In addition to a water allocation reserve for basic human needs, the policy includes a reserve allocation of water to support and protect the health of river systems, including ecosystem functions, to conserve biodiversity and secure ecosystem services they provide to society. Postel and Richter maintain that judicial rulings based on the public trust doctrine e. Ongoing River Restoration Efforts from around the World Chapter 4 suggest there is hope for re-establishing some semblance of river health.
A selection of river restoration projects including the Green River USA , the Sabie River South Africa and Brisbane River Australia provide examples of challenges in rebalancing manage- ment of water for human and ecosystem needs and illustrate the need for an adaptive management approach.
The authors maintain that equitable and sustainable use of rivers requires a participatory decision-making process in which citizens living within a river basin collectively define, through negotiation and dialogue, a shared vision for management and use. Postel and Richter argue that individual preferences will coevolve to shared goals with better knowledge and understanding of the natural functions of rivers, and suggest that tangible values for ecosystem services can be estimated by determining the cost of replacing the naturally-provided service with a technological or human engineered solution.
Science and scientists should be responsive to societal values reflected in watershed vision statements by guiding the adaptive management process for implementing the natural flow paradigm. In Rivers for Life: Managing Water for People and Nature, Postel and Richter have removed the blinders and illuminated the path for protecting and restoring the ecological services that we depend on and cannot replicate.
