The miracle that controlling the water rich north through dam building and moving water to the soil rich valleys has resulted in a breadbasket that provides food to the world, and it is continually threatened by an ideology that is built upon very shaky precepts; according to this must read article.
An excerpt.
“The great Central Valley of California has never been an easy place. Dry and almost uninhabitable by nature, the state's engineering marvels brought water down from the north and the high Sierra, turning semi-desert into some of the richest farmland in the world.
“Yet today, amid drought conditions, large parcels of the valley – particularly on its west side – are returning to desert; and in the process, an entire economy based on large-scale, high-tech agriculture is being brought to its knees. You can see this reality in the increasingly impoverished rural towns scattered along this region, places like Mendota and Avenal, Coalinga and Lost Hills.
“In some towns, unemployment is now running close to 40%. Overall, the water-related farming cutbacks could affect up to 300,000 acres and could cost up to 80,000 jobs.
“However, the depression conditions in the great valley reflect more than a mere water shortage. They are the direct result of conscious actions by environmental activists to usher in a new era of scarcity.
“To some extent, such efforts reflect some real limits imposed by the growth of population. Constructive long-term changes in the conservation and utilization of all basic resources – energy, water and land – are not only necessary, but also inevitable.
“Yet the new scarcity does not simply advocate humane ways to deal with shortages, but seeks to exacerbate them intentionally. This reflects a doomsday streak in the contemporary environmental ethos – greatly enhanced by the concern over climate change – that believes greater scarcity of all basic commodities, from land and water to energy, might help reduce the much detested "footprint" of our species.
“One key element of this agenda has to do with reducing access to critical resources like water beyond those required to support existing uses. To be sure, two years of below-average precipitation helped create central California's current water shortage. Planting crops such as cotton, which needs lots of water, may also have contributed to the problem.
“However, this only explains part of the problem, which increasingly has to do not with vicissitudes of nature but conscious political action. In prior dry periods, the state has managed its water resources to supply farmers and other users as effectively as possible. Today, in response to seemingly endless litigation to protect certain fish in the Delta region west of Sacramento or to "revitalize" valley streams, enormous amounts of water have been allowed to flow untapped into San Francisco Bay.”
