As general manager of a water district that serves about 27,000 agricultural acres in the southern San Joaquin Valley, Eric Averett knows the solutions to the region’s water shortages are fairly straight-forward.
He speaks of two knobs that valley water users can turn. One controls supply, and the other  demand.
In past years, Averett says he figuratively had his hand slapped by his Rosedale-Rio Bravo Water Storage District board whenever he tried to adjust the knob that affected the supply of water to growers. But as droughts, surface water cutbacks and groundwater overdrafts confront districts throughout the Central Valley, all solutions are now on the table.
“Throughout the valley, we’re going to end up turning both knobs in the future,” Averett said during a recent panel discussion on the valley’s water future.
In short, experts believe the only way to bring the valley’s overburdened water supplies into balance will be to increase supply, mainly by making the most of available water, and reduce demand. And part of reducing demand may well be the voluntary fallowing of agricultural land.
“For some of our hardest-hit areas, the idling of agricultural land is going to be a reality,” says Abbey Hart, the agriculture project director for The Nature Conservancy. She adds that growers may see an economic benefit for converting land into wildlife habitat, but the process will have to be well planned. A checkerboard approach to creating habitat won’t work, she says.
“A lot of these species won’t be able to use tiny patches of land,” Hart told about 200 growers and others at the water forum in early May, sponsored by the Almond Board of California.

hen John Wick and his wife, Peggy Rathmann, bought their ranch in Marin County, Calif., in 1998, it was mostly because they needed more space. Rathmann is an acclaimed children’s book author — “Officer Buckle and Gloria” won a Caldecott Medal in 1996 — and their apartment in San Francisco had become cluttered with her illustrations. They picked out the 540-acre ranch in Nicasio mostly for its large barn, which they planned to remake into a spacious studio. Wick, a former construction foreman — they met when he oversaw a renovation of her bathroom — was eager to tackle the project. He knew the area well, having grown up one town away, in Woodacre, where he had what he describes as a “free-range” childhood: little supervision and lots of biking, rope-swinging and playing in the area’s fields and glens.
The couple quickly settled into their bucolic new surroundings. Wick began fixing leaks in the barn. Rathmann loved watching the many animals, including ravens, deer and the occasional gopher, from the large porch. She even trained the resident towhees, small brown birds, to eat seed from her hand. So smitten were they with the wildlife, in fact, that they decided to return their ranch to a wilder state. For nearly a century, this had been dairy country, and the rounded, coastal hills were terraced from decades of grazing. Wick and Rathmann would often come home and find, to their annoyance, cows standing on their porch. The first step they took toward what they imagined would be a more pristine state was to revoke the access enjoyed by the rancher whose cows wandered their property.
Within months of the herd’s departure, the landscape began to change. Brush encroached on meadow. Dried-out, uneaten grass hindered new growth. A mysterious disease struck their oak trees. The land seemed to be losing its vitality. “Our vision of wilderness was failing,” Wick told me recently. “Our naïve idea was not working out so well.”
Wick was especially bothered by the advance of a prickly, yellow-flowered invasive weed called the woolly distaff thistle. He pulled it, mowed it, doused it with herbicides. But the distaff kept moving into what had been pasture. He thought about renting goats to eat the weeds and brush, but they were too expensive. He even considered introducing wild elk, but the bureaucratic hurdles seemed too onerous.
Then Wick and Rathmann met a rangeland ecologist named Jeff Creque. Instead of fighting against what you dislike, Creque suggested, focus on cultivating what you want. Squeeze out weeds by fostering conditions that favor grasses. Creque, who spent 25 years as an organic-pear-and-apple farmer in Northern California before earning a Ph.D. in rangeland ecology, also recommended that they bring back the cows. Grasslands and grazing animals, he pointed out, had evolved together. Unlike trees, grasses don’t shed their leaves at the end of the growing season; they depend on animals for defoliation and the recycling of nutrients. The manure and urine from grazing animals fuels healthy growth. If done right, Creque said, grazing could be restorative.

California's Sustainable Groundwater Management Act (SGMA) established a framework for sustainable, local groundwater management. SGMA requires groundwater-dependent regions to halt overdraft and bring basins into balanced levels of pumping and recharge. As a result, agricultural land retirement is on the rise in the San Joaquin Valley, California’s largest agricultural region and home to the state's highest concentration of threatened and endangered species. In this assessment, The Nature Conservancy introduces the concept of strategic land retirement and restoration, an approach which seeks to help recover San Joaquin Valley threatened and endangered species by restoring agricultural land that is suitable as habitat and under threat of retirement. The authors identify 2.5 million acres of current agricultural lands that have high potential for restoration, 14% of which was fallowed at least once during the most recent drought. 

From the SJV Greenprint Phase II Summary Report:

"The San Joaquin Valley (SJV) is one of the world’s most productive agricultural regions; is a vital link in California’s complex water delivery and transportation systems; provides important habitat to protect biodiversity; and is a center for oil and solar energy production. The region has a unique set of assets and challenges related to its agricultural land, growing population centers, biodiversity, energy production, and water availability.

The San Joaquin Valley Greenprint project grew out of the San Joaquin Valley Blueprint... The Blueprint focused on urban challenges, particularly the relationship of land use to transportation, and developed a set of smart growth principles that should minimize development impacts on the non-urban lands of the Valley. The Blueprint revealed the need for better regional mapping of the Valley’s non-urban areas to assist land use and resource management decisions...

The SJV Greenprint is primarily a collection of maps, assembled as a comprehensive, interactive database that catalogs current conditions and trends related to the region’s resources. The maps and data collected for the SJV Greenprint are publicly available through the San Joaquin Valley Data Basin Gateway (http://sjvp.databasin.org)... The collection demonstrates how these resources are interrelated across political boundaries and how they are changing under the influence of population growth, changing land use practices, resource limitations, and changing climate. 

Phase I of the Greenprint focused on identifying and mapping Valley resources for the eight counties that comprise the San Joaquin Valley, including Kern, Tulare, Kings, Fresno, Madera, Merced, Stanislaus, and San Joaquin Counties... The compiled information includes over 100 datasets related to agriculture, biodiversity, energy, and water resources, as well as supplemental datasets including land use planning, transportation, soils, and land cover...

Phase II of the SJV Greenprint was intended to build on and extend the work in Phase I by demonstrating the real world utility of this information. The Demonstration Projects, described in Section IV, serve as case studies for the use of Greenprint data. A second objective of Phase II was to find an appropriate platform for these curated resources, specifically a host that could provide a user-friendly interface as well as the capacity to update and maintain the data. The San Joaquin Valley Gateway, hosted by Data Basin, was identified as the best platform... A third objective of Phase II was to shed light on key questions and insights into various resource management challenges in the Valley through outreach to experts, regional councils of government, and county planning directors...
