Sustainable development is on the policy agenda for the '90s. What does sustainability mean? Is it a realistic concept? Are water rights compatible with sustainable use? The Center's 16th annual summer conference, Sustainable Use of the West's Water, explores the meaning of sustainability in the context of the West's demands, development, and natural values. Presentations by leading experts address the broad concept of sustainable development, with a particular look at Arizona's experience. The focus is on efforts in several states to promote sustainable water use.
