Tragedies of Water Commons
Ground zero for the new regulatory environment for water use in California is September 17, 2014. The State Senate passed legislation that initiated--for the first time in recorded history--mandates for reporting groundwater use and requirements for all high priority (high-quantity, see below) ground water users to submit plans for pumping, monitoring, and managing groundwater use. Central Valley and Central Southern Coast are both priority areas for regulation.
Until last year California had legally maintained that water is best managed at the local level, which meant in effect unmanaged. Going even further towards rationalizing laissez-faire-laissez-allez, the Texas Supreme Court concluded in 1904 that groundwater was too “secret, occult, and concealed” to ever regulate. Net: groundwater, on which we all--worldwide-- depend for well-being of home and business, has not been well managed, with catastrophic results. Worldwide, water stored for millions of years is being rapidly depleted, with no quick fix in anyone's lifetime. But the idea of free water shared communally is about to radically change, albeit very possibly not "just in time."

Regardless, the days of the water occult are over. NASA satellite systems have not only revealed what was concealed, but they have published documents showing that throughout the world, both shallow and deep groundwater resources are being depleted more rapidly than can ever be replenished. Lack of good water management has led to possibly irreversibly damaging results: in California, the Middle East, parts of Africa, India, Pakistan, and China. Although this is an unprecedented disaster, the urgent usually pre-empts the important, and so it is with water. What we perceive as most urgent, as a species, is what is most likely to effect us today. Tomorrow's threats are discounted.
The fact that most water systems run regardless of borders has led to what is known as a tragedy of the commons, meaning resources once considered as free and belonging to everyone, are exploited by individuals, communities, and nations for their local self-interests to the point of depletion. As the world runs out of clean water, water use is being increasingly controlled, divisive, and fought for and over: so it pays each of us to know our water and its ways.

Runs Deep
The water running deepest and oldest--perhaps millions of years, is fossil water, which like coal and oil is a non-renewable resource. The world's best known fossil water aquifers (rock storage structures)--the Ogalalla in the US, the Disi in Jordan, the Nubian in North Africa have been drawn down continuously over the past fifty years. Unlike fossil aquifers, when replenishable aquifers are drawn down, the pumping rate automatically defaults to the rate of recharge.When fossil water sources are depleted, the water has run out.
Runs Shallower
Shallower is the water that supplies the demands of over 30 million Californians and irrigates more than 5,680,000 acres of farmland. The source of this supply is rain and snow that falls to earth, surface water that has accumulated over time above ground and in top soils, and water that has trickled over hundreds maybe thousands, of years into aquifers underground--so-called ground water. All are complex and as far as individual demand goes, unreliable. Both surface and ground water are increasingly regulated by increasingly remote agencies.
Stakeholders who hope to participate in and influence the oncoming regulations need to understand basic hydrology, particularly as it pertains to their habitats. Both the privileges and responsibilities of stewardship come with knowledge..
Increased demand on Constant or Diminishing Supply
The increased demand for water by a population of over 7 billion has led to depletion of groundwater, which recharges mainly from precipitation, but in most regions of the world, much slower than current demands.The USDA reports that in parts of Texas, Oklahoma, and Kansas-—three leading grain-producing states-—the underground water table has dropped by more than 30 meters (100 feet). As a result, wells have gone dry on thousands of farms in the southern Great Plains and are drying up in California's Central Valley and in Southern California.
Central Valley California agribusiness is possibly among the world's worst offenders of groundwater exploitation, but as the world's breadbasket and major revenue producer in California and the US, agribusiness pushes hard on legislators to go slow and easy with reform. Recent mandates in California have targeted residential and urban use and ordered farmers to become planners, but for now, not much more.
Prolonged drought causes water users to seek supplies underground. Because ground water (underground water) is concealed and unmanaged,it is easily exploited, which results in the fresh water disaster facing us today--worldwide. Typically, early responses include attempts at controlling loss through legislation, which is what is happening in California today--early summer 2015.
Stakeholders who would like to participate in their regulatory water futures can start by understanding what is at stake. What are the key concepts and facts anyone hoping to make informed decisions and action must understand? Californians need to know where their water comes from, who uses it and manages well and who doesn't, what are aquifers, recharge, etc., what are the great water projects that have turned the Central valley into the most productive agricultural region in the world--artificially.
This post highlights the ground water problem using images from water stressed regions around the world to condense complex information into a simple informative snapshot.
The next post summarizes key water concepts such as replenishable vs fossil aquifers, water footprints and diverse meanings for different contexts, and agribusiness water supply systems, with a focus on California water and agriculture, using the Central valley and Southern Central Coast wine industries as illustrative cases.
The third post in this 3-part series looks at how stakeholders might influence water management legislation over the next ten years. Continuing from post two, the inseparability of water, food, agriculture, and economic issues in California is exemplified using the powerful economic determinative of the Wine Industry in the Central Valley and Southern Coastal areas of California.

"For fossil aquifers—such as the vast U.S. Ogallala aquifer (US), the deep aquifer under the North China Plain, or the Saudi aquifer—depletion brings pumping to an end. Farmers who lose their irrigation water have the option of returning to lower-yield dryland farming if rainfall permits." http://www.eoearth.org/view/article/150159/

The Middle East lost 117 million acre feet
of freshwater between 2003 and 2009, compared to 20 million lost in
the Central Valley over the past 10 years. About one-fifth of the loss
in the Middle East is attributed to drought.; one-fifth was lost from
surface water resources such as lakes and streams and about 60 % drained
for agricultural purposes from aquifer n not recharging fast enough.
