by Peter Gleick and Heather Cooley Debates about water in California, the western U.S., and indeed, worldwide, have traditionally focused on the question of how best to further expand water supply to meet some hypothetical future increase in water demand. And the solution frequently offered is to build massive new infrastructure in the form of…

  If there is anything that the past few decades of research and study of major global challenges tells us, it is that truly effective solutions to sustainability challenges require truly integrated approaches across disciplines, fields of study, data sets, and institutions. We are not going to solve 21st century global problems with 20th century…

By Peter Gleick (Pacific Institute) and Carl Ganter (Circle of Blue) 1. The California Drought Becomes an Emergency California’s multi-year drought grew dire enough in 2014 to prompt Governor Jerry Brown to declare a drought emergency in January. By the end of the year, California had experienced the driest and hottest 36 months in its 119-year…

Over the past three years (and indeed, for 10 of the past 14 years) California has experienced a particularly deep drought. How bad is the drought? Is it the worst in the instrumental record? The worst in over a century? The worst in 1200 years? The worst “ever”? And why has it been so bad?…

Guest Post: Matthew Heberger Pacific Institute, Oakland, California New monthly water use data for California water utilities shows that residential water use varies widely around the state, and that the response to the drought has been uneven. Moreover, in some areas, residential use averages more than 500 gallons per person per day, indicating that we…

I previously posted a summary of the water-related conclusions from the new National Climate Assessment, recently released after three years of writing, review, and analysis. The following “findings” are a broader summary of the results from the newly released National Climate Assessment (NCA). They are by no means a full summary: far more detail can…

The end of the rainy season in California is arriving in a few weeks, and the April 1st snowpack measurement, which is a key indicator of water conditions, is tomorrow. As we approach the dry spring and summer months, the scope and severity of California’s drought will become more apparent, but it is already clear…

In the last few months, as the severe California drought has garnered attention among scientists, policymakers, and media, there has been a growing debate about the links between the drought and climate change. The debate has been marked by considerable controversy, confusion, and opaqueness. The confusion stems from the failure of some scientists, bloggers, reporters,…

It is time to recognize the serious California drought for what it is: a bellwether of things to come; a harbinger of even more serious challenges to California water resources allocation, management, and use. The drought could end next month. It could go on for more years. But it will not be the last drought…

Water policy and water problems always seem to be someone else’s responsibility. Those farmers who use all the water; the guy down the street who lets his sprinklers run all over the sidewalk; the Central Valley cities that don’t even have water meters; the environmentalists who are demanding water for some inconsequential fish we can’t…
