Heather Cooley and Peter Gleick California is in a severe drought – four years long now. But what does the drought really mean for the things we care about: food production, fisheries, industrial activities, rural communities? As part of the work of the Pacific Institute to evaluate both the impacts of water problems and identify…

It’s only natural that during a crisis we look to single, “silver bullet” technical solutions, after all, they are supposed to be effective against werewolves, witches, and other monsters. For monsters like the ongoing severe California drought, the current favorite silver bullet is seawater desalination.  And why not? California sits at the edge of the…

[As part of the Pacific Institute’s ongoing efforts to evaluate the impacts of the California drought and offer strategies, technologies, and policies to reduce those impacts, we are presenting a series of short assessments on “Understanding the Numbers.” This piece is the part of that series.] California is a wonderful place to grow food. The…

In a new study just published by the journal Sustainability Science (Springer), analysis from the Pacific Institute (with lead author Dr. Juliet Christian-Smith, now at the Union of Concerned Scientists) shows that many of the fundamental responses of California water users to severe drought actually make the state’s overall water conditions worse – that in the end,…

In the past few weeks, I have had been asked the same question by reporters, friends, strangers, and even a colleague who posts regularly on this very ScienceBlogs site (the prolific and thoughtful Greg Laden): why, if the California drought is so bad, has the response been so tepid? There is no single answer to…

California has a “Mediterranean” climate, which means that each year it has a concentrated rainy season, followed by a long temperate and dry period. California’s rainy season typically runs from early October to late March, with very little precipitation outside of these months. (Figure 1 shows the average monthly rainfall for California.) It is now…

The Colorado River, recently named America’s most endangered river, supports millions of people in the American Southwest and northwest Mexico and helps irrigate millions of acres of land. It is shared by seven states in the U.S. and Mexico, through a complex series of legal agreements and treaties. Yet every drop of water on the river…

The Pacific Institute has done extensive and groundbreaking research over the past 25 years on a wide range of water, climate, energy, and environmental issues. One focus has been on how to use water more efficiently to do the things we want to do – a focus on “efficiency” and “productivity” – not deprivation. Society could…
