My new Science Magazine article “Water Strategies for the Next Administration” has just been released (embargo lifts 11am Pacific, November 3rd; the print version will appear in the November 4th issue of Science). It identifies six major water-related challenges facing the United States and offers explicit recommendations for strategies the next Administration and Congress should pursue, domestically and internationally. The article begins:
“Issues around fresh water are not particularly high on the U.S. political agenda. They should be. Water problems directly threaten food production,…

“Recognizes that the current long-term drought across much of the West poses a dire risk to the health and prosperity of Western communities and believes the federal government can and should be a better partner in supporting state and locally-led efforts to improve water security.”

Populations around the world face many severe water challenges, from scarcity to contamination, from political or violent conflict to economic disruption. As populations and economies grow, peak water pressures on existing renewable water resources also tend to grow up to the point that natural scarcity begins to constrain the options of water planners and managers. At this point, the effects of natural fluctuations in water availability in the form of extreme weather events become even more potentially disruptive than normal. In particular, droughts begin to bite deeply into human well-being…
Since its founding in 1987, the Pacific Institute has worked to understand the links between water resources, environmental issues, and international security and conflict. This has included early analytical assessments (such as a 1987 Ambio paper and this one from the journal Climatic Change) of the risks between climate change and security through changes in access to Arctic resources, food production, and water resources, as well as the ongoing Water Conflict Chronology – an on-line database, mapping system, and timeline of all known water-related conflicts. In 2014, an analysis of the…

Water was a Top Risk on the 2015 Global Agenda
In early 2015, participants at the World Economic Forum, a who’s who of the political and business elite, ranked water crises as the top global risk. Water was also a key factor in the adoption by the United Nations General Assembly of the Sustainable Development Goals (SDGs), a blueprint for international development over the next 15 years. Ensuring safe drinking water and sanitation for all by 2030 is one of six water goals for the SDGs. In December at the UN climate change conference in Paris,…

The recent severe drought in the Western United States -- and California in particular -- has shined a spotlight on a range of water-management practices that are outdated, unsustainable, or inappropriate for a modern 21st century water system. Unless these bad practices are fixed, no amount of rain will be enough to set things right. Just as bad, talking about many of these bad practices has been taboo for fear of igniting even more water conflict, but the risks of water conflicts here and around the world are already on the rise and no strategy that can reduce…

Last week, the Pacific Institute published the first comprehensive analysis of the impacts of the drought on California crop revenue and agricultural employment through 2014. The study showed that during the recent drought California’s agriculture sector experienced record-high crop revenue and employment. Crop revenue peaked in 2013 at $33.8 billion, the highest level in California history, and declined only slightly to $33.4 billion in 2014 (all economic data have been corrected for inflation). Statewide agriculture-related jobs also reached a…

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 smart solutions, we’ve just released the first comprehensive assessment of the actual impacts of the drought for California agriculture.
Many commentators and analysts have worried especially about California’s agricultural sector, which is a major water user and has…

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 dams and reservoirs, drill more groundwater wells, or expand water diversions from ever-more-distant rivers, in order to “grow” the supply available for human use.
“Build more traditional water infrastructure” is increasingly the wrong answer to the…
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 largest body of salt water in the world – the Pacific Ocean – and taking salt out of water is a successful, commercial, well-understood technology.
Look at how Israel has solved their water problems by building desalination plants, we’re told…
[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 climate is highly favorable; soils are some of the best in the world, it is located well to serve global distribution markets with major ports and other transportation infrastructure; and normally, some regions are relatively well-watered.
Normally.

California’s hottest and driest drought in recorded history has shifted the sources of electricity with adverse economic and environmental consequences. The Pacific Institute has just completed and released a report that evaluates how diminished river flows have resulted in less hydroelectricity, more expensive electricity from the combustion of natural gas, and increased production of greenhouse gas emissions.
The current severe drought has many negative consequences. One of them that receives little attention is how the drought has fundamentally changed the way our electricity is produced.…
The California drought continues.
While we do not know yet what the rest of the wet season will bring – and while we hope for the major storms needed to recharge our rivers, groundwater and reservoirs – it seems increasingly likely that California will not see enough precipitation to get out of the very deep deficit that three years of drought (so far) have produced.
There is, however, some misleading and confusing information out there. Some are already arguing that California’s rainfall is nearly back to normal or that because there may have been more serious droughts in the past we needn’t…
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?
There is no single definition of “drought.” Drought, most simply defined, is the mismatch between (1) the amounts of water nature provides and (2) the amounts of water that humans and the environment demand. As the National Drought Mitigation Center puts it:
“In the most general sense, drought originates…
The most important trend in the use of water is the slowly unfolding story of peak water in the United States and elsewhere. Data on US water use are compiled every five years by the US Geological Survey, covering every state and every sector of the economy. The latest data – for 2010 – have just been released, and they show the continuation and acceleration of a stunning trend: US water withdrawals, for all purposes, are declining, not growing.
Traditional water planning and management assume inevitable, continuing, lockstep growth in demand for water as populations and economies expand.…
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, many of these actions are “maladaptations.”
Water is a complex resource; and water problems are an equally complex mix of natural resource, technology, social, economic, and political conditions. When water is limited, such as in…
In the 20th century, society was either ignorant of, or ignored, the consequences of bad water management. The goal was economic development at all costs. Over the past few decades, we've learned about the ecological and social implications of the misuse of water, and some efforts have been made to protect natural ecosystems, restore a modicum of flows, bring local communities into the discussion about water policy and infrastructure. These are steps in the right direction.
But sometimes our failures have been monumental -- and uncorrected.
Perhaps the best, or worst, example, is the complete…
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 this question (and of course, it presumes (1) that the drought is bad; and (2) the response has been tepid). In many ways, the response is as complicated as California’s water system itself, with widely and wildly diverse sources of water, uses of water, prices and water rights,…
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 be found in the chapters and the regional syntheses, but these are noteworthy conclusions. (Note, thanks to Tim Smith – Sustainable Water Resources Coordinator – for highlighting these. The page numbers refer to the NCA Summary)

Snapshots from the New National Climate Assessment
After three years of intensive effort, research, writing, and review by hundreds of climate scientists, the latest update of the U.S. National Climate Assessment was released today. It includes many long, carefully prepared sectoral and regional studies, and covers the massive range of effects of climate change on the nation, including both changes already observed and expected in the future.
There are hundreds of pages of information, observations, projections, and conclusions to absorb – almost all of it bad news. Here, in short form and in…
