Last Oasis (W.W. Norton, 1992, revised 1997)

Selected by Choice magazine as a 1993 Outstanding Academic Book.

Appearing in eight languages and the basis for a 1997 PBS documentary, Last Oasis frames the many dimensions of the world’s water challenges and demonstrates how conservation and efficiency improvements can meet new water needs at lower economic and environmental costs than traditional supply projects. These measures constitute our “last oasis” – and they have barely been tapped. Postel calls for a water ethic that places the preservation of freshwater ecosystems at the heart of water management.

“Last Oasis is the call to arms most often cited by others in the field.” — Marq de Villiers, author of Water: The Fate of our Most Precious Resource

Last Oasis “is marked by lucidity, balance, levelheadedness and, at bottom — and for this we can be thankful — optimism.  Los Angeles Times Book Review.

The PBS documentary, Last Oasis, produced and directed by Linda Harrar, is program four in the Cadillac Desert film series. Learn more about Last Oasis.
