Peter Gleick: What Do You Know? Water Conservation and Efficiency Actually Work

A new analysis from the Pacific Institute Municipal Deliveries of Colorado River Basin Water, authored by Michael J. Cohen, documents real changes in population and water deliveries for 100 cities and water agencies in the U.S. and Mexico that deliver and use water from the Colorado River Basin. Total population in these areas grew by more than 10 million people between 1990 and 2008, but water use per person dropped by around 20 percent over the same period (around 1% per year).

Peter Gleick: The California Drought (2007-2009) – Myth Versus Reality

California has just come out of a bad three-year drought. 2007, 2008, and 2009 were dry or “critically dry” according to official drought categories for most of the state. Past droughts have been both more severe (1977-1978) and longer in duration (1987-1992) than […]

Peter Gleick: Playing God

In a desperate attempt to make it easier to solve California’s complex and contentious water problems, a dangerous new idea has recently been floated — intentionally letting some species go extinct rather than take the difficult steps needed to save them and their ecosystems. This idea should be quashed, smothered, strangled, and quickly tossed in […]

Peter Gleick: Peak Water

Peak water is coming. In some places, peak water is here. We’re never going to run out of water — water is a renewable natural resource (mostly). But increasingly, around the world, in the U.S., and locally, we are running up against peak water limits. The concept is so important and relevant that The New York Times chose the term “peak water” as one of its 33
