Groundwater Farming: a Blessing or a Curse?

By Michael Kuhne, AccuWeather.com

Mining groundwater for agricultural use in the San Joaquin Valley has not only created one of the most productive agricultural regions in the United States, but it has also simultaneously altered the surface of the land causing noticeable subsidence or sinking in the region, according to the U.S. Geological Survey.

“The maximum subsidence, near Mendota, was more than 28 feet,” USGS reported, citing a 1970 comprehensive survey.

Overall subsidence has slowed since the 1970s due to reductions in the pumping and recovery of groundwater, as well as the use of other types of surface water irrigation.

“At least some of the groundwater is stored in between clay deposits and within clay deposits,” AccuWeather.com Senior Meteorologist Ken Clark said. “When you extract the water, you take out the water surrounding (the) clay molecules, and this then allows the clay to compress. The more water you take out, the more compacting you have, and when that happens, the valley sinks.”

According to U.S. Department of Agriculture National Agricultural Statistics Service Pacific Region Office Deputy Director Dave DeWalt, nearly 11.3 percent of the total value of U.S. agriculture commodities comes from California’s prime agricultural region.

“So far (in 2014) we’ve only seen about one-third of the precipitation we normally would have,” DeWalt said, referring to the Sacramento area.

With the drought continuing, food prices will spike.

“It is some of the richest farmland in the U.S.,” Clark said. “There is talk that some commodities may not be feasible as they take a lot of water to grow. Such as almonds, a huge cash crop. It takes one gallon of water to make one almond.”

According to Fresno State University Center for Irrigation Technology Consultant Sergeant Green, understanding the utilization of groundwater and the impacts on the Valley is not as simple as it seems.

“Water, crops and productivity are all dynamic,” Green said.

The current crops using the most water in the region are almonds and alfalfa, he said.

“Almonds are a critical export that helps with balance of trade, and alfalfa is critical for the dairy industry which is a huge part of the agriculture economy in the Valley,” Green said. “The three top agricultural commodities are almonds, grapes and dairy products.”

The San Joaquin Valley is part of the Central Valley of California, includes the Sacramento Valley and the Sacramento-San Joaquin Delta. This area produces about a quarter of the nation’s table food on only 1 percent of the country’s farmland, USGS reports.

“Groundwater in the north of the Valley is relatively stable, the south Valley (Fresno south to Bakersfield) has declined consistently,” Green said. “Old pre-1960s subsidence stopped until surface water supplies from the Bay-Delta were cut back starting in the mid-’90s.”

According to the USGS, land subsidence in the Valley was first recorded in 1945 by Engineering Consultant I.H. Althouse.

“The history of land subsidence in the San Joaquin Valley is integrally linked to the development of agriculture and the availability of water for irrigation,” the USGS reported. “Further agricultural development without accompanying subsidence is dependent on the continued availability of surface water, which is subject to uncertainties due to climatic variability and pending regulatory decisions.”

The 10,000-square-mile area making up the Valley floor is comprised of continental sediments and includes fine-grained, stream and lake deposits, which are susceptible to compaction, the USGS reported.

“When farmers and ranchers have to rely on groundwater instead of stored above ground water during extended droughts, more water is being extracted than can be returned,” Clark said. “Once the clay is compacted, there is no way to ‘unpack’ it.”

According to AccuWeather.com Meteorologist Randy Adkins Jr., California has received less than their average rainfall for several years consecutively.

“It’s been a multi-year drought,” he said.

AccuWeather.com Meteorologist Jim Andrews said the last three winter rainy seasons (October to April) were drier than normal, the last winter being driest of the three. Cumulative rainfall (including melted snow) is as little as one half of normal amount for the three rainy seasons collectively, Andrews said.

“Fresno has only seen 55 percent of their normal for those three seasons,” he said. “That’s around 16 inches of rain less than normal.”

Andrews added that the Sacramento region has been doused with only 68 percent of their normal rainfall of 54.5 inches.

Green said rainfall is not adequate to recharge the groundwater, adding it needs to be stored, applied or recharged in specific areas that allow the capability to add more water than what is being extracted at those locations.

In addition, new developments in irrigation are being utilized currently, but the amount of water needed will continue to be based on what crops are in demand, Green said.

“Precision irrigation systems are now widespread and continuing to increase rapidly, but don’t always mean less water is used,” he said. “Crop requirements determine total demand, and permanent crops such as almonds have been increasing for some time.”

Valley Citrus Growers Receive 0% Water Allocation; Citrus Growers Available for Interviews April 23, 2014!

Late last week, the California Department of Water Resources (DWR) announced that rain and snow storms in February and March have allowed an increase of water contract allocations for State Water Project deliveries from zero to five percent.

Although this appears to have been positive news for agricultural interests in the San Joaquin Valley, it is far from it.  The DWR announcement went on to state that the precipitation from these recent storms eliminates the need for rock barriers to be constructed in the Delta.  This means that the increase in water deliveries will be flushed into the ocean in order to protect fish species and prevent saltwater intrusion in the Delta. San Joaquin Valley agriculture remains at zero percent allocation.

Approximately 75% of the California citrus crop is produced in Tulare, Kern, and Fresno Counties.  A majority of this acreage relies on surface water from the Friant-Kern Canal.  DWR’s delivery increase does nothing to reduce the pressure on the Friant from exchange contractors who would otherwise receive their water via the State Water Project.

Earlier this month, the DWR and State Water Resources Control Board (SWRCB) released a 168-page document they refer to as the “plan.”  However, the plan does not refer once to the people or the economy that will be impacted by zero water allocation to agriculture.  The word “farmer”, or “agriculture”, appears once.  The word “fish” is stated 328 times.

“Friday’s announcement was made with much fanfare and yet the decision completely ignores the East side of the San Joaquin Valley, and even stipulates that we are not important,” says CCM President Joel Nelsen.

The photo above depicts “petal fall” and the first life stages of an orange, when the blooms have fallen.  It is at this critical point of the growing season, when we enter into the hottest months of the year, that sufficient water is available for the cultivation of the crop.

California is the Nation’s number one supplier of fresh citrus. “Our Valley is the number supplier of fresh fruits and vegetables and yet that does not enter into the equation for water needs,” continues Nelsen.  “What ever happened to the goal of providing a bountiful array of fresh produce at affordable prices?”

The Friant-Kern Canal needs at least 200,000 acre-feet to remain functioning.  The decision not to release sufficient water to the State Water Project guarantees that exchange contractors will call upon their first rights to water supplies in Millerton Lake and reduce the amount that would otherwise flow to the Friant-Kern Canal.  This decision is forcing growers to make their own decision – between pushing out trees and holding out for water that may come too late, or not at all. Over 50,000 acres of citrus in the San Joaquin Valley is at risk. But, it is not just trees that will be pushed if Friant does not receive water – jobs will be pushed, people will be pushed, and the economy will surely suffer.

“I continue to be mystified by the announcement last Friday and the inconsistencies it presents,” says Nelsen.  “The announcement on Friday and previous announcements all state that the public should strive to conserve at least 20% of their normal water use.  Yet the producers I represent, and for that matter all producers on the Eastside of the San Joaquin Valley, are being told to give up 100% of their water.  In fact, those in the Friant Service area are the only contractors being asked to give up 100% of their water.”

This situation is real and devastating for many family citrus farmers.  Here are a just a few growers who are facing zero water allocations. 

Andrew Brown

These growers, and others, will be available for interviews tomorrow, April 23rd at 2:00 p.m. at the Lamp Liter Inn in Visalia.  Please provide advanced notice to Alyssa Houtby, 559-737-8899 if you plan to attend. 

 

Andrew Brown, a fourth generation citrus grower in the Orange Cove, Orosi/Cutler area works alongside his father and brothers on his family’s farm.  Andrew has known since college he would follow in his father’s footsteps and return to faming because it is a rewarding business mentally, spiritually, financially. Now he has his own ranch where, one day, his two young children want to be second generation farmers.  

 

Gus Carranza

Gus Carranza grew up picking oranges in the San Joaquin Valley alongside his parents. He worked through school as a truck driver for a farming operation. His career in the citrus industry eventually led him to work for a major citrus grower-shipper operation.  He now manages their field department.

In 2000, he started farming his own acreage in Terra Bella with his brothers.  What began as a 10-acre operation has now expanded to 130 acres.  Carranza has received zero surface water this year. Unless something changes, he will watch his trees die, and watch his investment of $30,000 per acre die with them.

Maribel Nenna works for a packing house in Southern California as the operation’s field advisor in the Central Valley. Ten years ago, she and her brother took their passion for the citrus industry and purchased 10 acres of citrus. Today, they farm 40 acres – all have received zero water allocation. In two weeks those trees, approximately 135 trees per acre, will lose their crop if they do not receive water.

Matt Leider is a 5th generation citrus producer.  He grew up working on his mother’s ranch in Southern California before going to college. His involvement in the citrus industry is now two-fold.  He works on his uncle’s citrus ranch in Porterville, and manages a successful mechanical pruning business that services citrus growers throughout the Valley.  He needs one acre-foot of water per acre just to keep his family’s citrus acreage alive, but he doesn’t have it.

Carlos Gutierrez came to Lindsay when he was four years old. In 1999 he started a portable restroom business servicing citrus harvest crews.  He then bought 12 acres of citrus on his own in 2001.  Now, he manages harvesting crews for a packing house and owns over 100 acres on his own.  He has a little water, but not enough to keep all of his acreage alive.

 

Jesus Ramos farms 86 acres in Terra Bella and another 50 acres in Strathmore.  He put down a deposit of $600 per acre-foot for water, and now hopes to find water at $1,200 an acre-foot.  But, he can’t find any because none is available.  He hopes to save his best acreage because he knows he can’t save everything.

 

The California citrus industry is dominated by family farmers.  “Everybody talks about protecting the family farmer, but by denying surface water to the Friant service area the state’s water agencies are aiding in their demise,” concludes Nelsen.

Federal Plans Begin to Address Climate Realities

Source: Dru Marion; CalCAN

Despite producing mixed results for sustainable agriculture interests, President Obama’s 2015 budget request is an encouraging sign that the federal government is getting serious about climate change, and particularly about adapting to its impacts.

The President’s proposal includes a $1 billion dollar Climate Resilience Fund, which is intended to strengthen preparedness of states and communities for increasingly extreme weather like floods, droughts, and wildfires.

The fund would support investment in research, technologies, and infrastructure across numerous agencies and sectors, including agriculture.

Word of the fund first came out in February, when Obama met with growers and ranchers in the San Joaquin Valley, the heart of drought-stricken California.

While touring the farm of Joe and Maria Del Bosque, who have fallowed their melon fields due to water shortages, the President emphasized the role federal support could play in alleviating drought impacts and preparing for the future.

“A changing climate means that weather-related disasters like droughts, wildfires, storms, and floods are potentially going to be costlier,” he noted, “And they’re going to be harsher.”

More and more, the President’s administration seems to be acknowledging the link between climate change and adaptation needs in agriculture.

Last month’s visit from the President followed close behind Agriculture Secretary Tom Vilsack’s announcement that the USDA will be launching seven ‘Climate Hubs’ across the country, intended to “deliver science-based knowledge and practical information to farmers, ranchers and forest landowners within each region of the United States to support decision-making related to climate change.” (See the USDA fact sheet).

It is uncertain exactly how the Climate Hubs will be funded, however, and USDA Climate Change Program Office Director Bill Hohenstein has declined to comment on the overall estimated costs of the program.

Meanwhile, the 2015 budget request for USDA comes in at $23 billion – about a billion dollars below FY2014 levels. The Climate Resilience Fund is an obvious place to provide needed financial support to the Climate Hubs, but it remains unclear as to whether the President intends for the Fund to provide that support, and also whether Congress will approve the expenditure.

Despite these uncertainties, National Farmers Union President Roger Johnson has voiced his support for Obama’s budget plan, saying, “The President’s proposed Climate Resilience Fund will provide farmers and ranchers with much-needed assistance after extreme weather events, which are occurring with increasing frequency.”

A growing acknowledgement of the link between climate change and agriculture on a federal level is heartening, to be sure, but it is worth noting that the budget plan leaves significant room for improvement with regard to sustainable ag programs more generally.

The California Climate and Agriculture Network (CalCAN) brings a sustainable agricultural perspective to climate change and agriculture policy. Their efforts are aimed at increasing funding for research, technical assistance and financial incentives for farmers whose practices reduce GHG emissions, sequester carbon, and provide many environmental co-benefits.
