Commentary: Proposed EPA ‘waters’ rule hangs farmers out to dry

Source: Don Parrish; Ag Alert

The U.S. Environmental Protection Agency proposal to expand the scope of “navigable waters” subject to Clean Water Act jurisdiction was drafted, according to the agency, to reduce uncertainty. It’s very clear the proposed waters of the U.S. rule is designed to allow the federal government to regulate every place water flows when it rains, including small and remote “waters” and ephemeral drains and ditches.

We all know that water flows downhill and that at some point, some of that water eventually finds its way into a creek, stream or river. Yet, based on nothing more than the flow of rainwater along a natural pathway across the land, the EPA wants to call vast areas of otherwise dry land “tributaries” and therefore “navigable waters.”

With its proposal to regulate land that is dry most of the year and miles from the nearest truly navigable water, EPA is putting farmers in a tenuous position. EPA and other supporters of the proposed rule have made much of a long-standing exemption for agriculture, and claim that it still stands; however, the proposed rule narrows that exemption and opens it up to litigation. The “normal farming and ranching” exemption only applies to a specific type of Clean Water Act permit for “dredge and fill” materials. There is also no farm or ranch exemption from Clean Water Act permit requirements for what EPA would call “pollutants.”

Ultimately, the new permitting requirements that would come with this proposal would mean that common farm activities could trigger Clean Water Act liability and the need for Section 402 National Pollutant Discharge Elimination System permits if pollutants could incidentally be deposited into ditches, ephemerals and other features that will now fall under federal jurisdiction.

At the same time EPA and the U.S. Army Corps of Engineers are telling farmers and ranchers they’re got nothing to worry about because the exemption puts them in the clear, the agency is moving forward with a guidance document that will govern how it interprets the “normal farming” exemption contained in Section 404 of the Clean Water Act.

This interpretive rule makes fundamental changes in how the exemption for normal agricultural activities at “established” farms will be applied and enforced. Contrary to assertions by proponents, this interpretive rule narrows how the exemption is applied and increases farmers’ liability by requiring that farmers comply with Natural Resources Conservation Service conservation standards, which were previously voluntary, in order to be exempt from Section 404 permitting.

Like the proposed waters of the U.S. rule, the interpretive rule conflicts with congressional intent. In 1977, Congress amended the Clean Water Act to exempt “normal” farming, ranching and silviculture from Section 404 “dredge and fill” permit requirements. However, EPA and the Corps are now asserting that farmers are exempt from Section 404 permits so long as any of 56 listed practices comply with NRCS standards, despite the fact that those practices have qualified as the “normal” farming, ranching and silviculture activities for 37 years.

The newly proposed interpretation of “normal farming and ranching” would apply only to farms and ranches that EPA determines to be “established” and “ongoing”—not newer or expanded farms and ranches. Where does this leave the children and grandchildren of farmers and ranchers who want to work the land but need to grow the operation to support an expanding family? What does this mean for the billions of people who will need to be fed in the future?

Worried about the answers to those questions and the many threats the proposed rule poses to agriculture, the American Farm Bureau Federation launched a website at ditchtherule.fb.org to help farmers, ranchers, landowners and others express the need for EPA to “Ditch the Rule.” Focused on topics and analysis related to the proposed rule, the site includes several sections: Take Action, Go Social, Find Answers and Get Resources. We encourage you to visit the site, sign up to learn more, comment on the proposed rule and send tweets using the hashtag #DitchTheRule. You should also voice your concerns to your state and local officials and your U.S. representative and senators.

Forest Fires Could Be Impacting Winegrapes

Smoke Taint Could Cause Off-Flavor Vines

Many forest fires throughout California have been near or upwind from many winegrape vineyards and could be causing problems for the grapes.

Jim Kennedy, a professor and chairman of the Department of Viticulture and Enology at the California State University of Fresno, explains a particular serious problem due to smoke enveloping vineyards.

“A lot of these fires are getting very close to the wine industry, and that’s a problem because the smoke that these fires generate, they come in contact with clusters of fruit. The compounds that are smoke get absorbed onto the fruit and the plant likes to modify these compounds, because it can be quite toxic to plant cells,” said Kennedy. “The wine gets made from that fruit and the wine ages, the smoke compounds become released again, and it’s a real problem. Your wine starts to resemble an ashtray, its smell and character,” he added.

Kennedy said the tragedy is that the fruit is exposed to the smoke and it’s not readily and obviously upfront as problematic.

“A winemaker goes through the wine-making process thinking their fruit has escaped the problem, and low and behold a year down the road its become an ashtray. And that is something as the grape and wine industry we’re really keeping an eye out on these forest fires, and consulting with winemakers in these different regions so they are aware that this is a potential issue,” said Kennedy.

Kennedy said that this problem, also known as “smoke taint” has been seen many times.

“The classic sample is Australia. With the bush fires in Australia a lot of the vineyards are very close to eucalyptus groves, and so there’s a lot of research that has come out of Australia in terms of how to measure the potential for smoke taint in fruit and how to deal with it once you got it. The Australians tend to be on the front-end of it because it’s an issue that has much more potential for disaster in their industry,” said Kennedy.

Native ecosystems blitzed by drought

Source: Alexandra Witze and Nature Magazine; Scientific American

Peter Moyle has seen a lot in five decades of roaming California’s streams and rivers and gathering data on the fish that live in them. But last month he saw something new: tributaries of the Navarro River, which rises in vineyards before snaking through a redwood forest to the Pacific, had dried up completely.

“They looked in July like they normally look in September or October, at the end of the dry season,” says Moyle, a fish biologist at the University of California, Davis.

Blame the drought. The Navarro and its hard-pressed inhabitants are just one example of stresses facing a parched state. From the towering Sierra Nevada mountains — where the snowpack this May was only 18% of the average — to the broad Sacramento–San Joaquin river delta, the record-setting drought is reshaping California’s ecosystems.

It is also giving researchers a glimpse of the future. California has always had an extreme hydrological cycle, with parching droughts interrupted by drenching Pacific storms (see ‘Extreme hydrology’). But scientists say that the current drought — now in its third year — holds lessons for what to expect 50 years from now.

“The west has always gone through this, but we’ll be going through it at perhaps a more rapid cycle,” says Mark Schwartz, a plant ecologist and director of the John Muir Institute of the Environment at the University of California, Davis. He and others are discussing the drought’s ecological consequences at the annual meeting of the Ecological Society of America, which runs from August 10 to 15 in Sacramento, California. He says that the state’s plant and animal species are at risk in part because California ecosystems are already highly modified and vulnerable to a variety of stresses.

Many of the state’s 129 species of native inland fish, including several types of salmon, are listed by federal or state agencies under various levels of endangerment. “We’re starting from a pretty low spot,” says Moyle. He hopes to use the current drought to explore where native fish have the best chances of surviving.

That could be in dammed streams such as Putah Creek near the Davis campus, where water flow can be controlled to optimize native fish survival. Another focus might be on spring-fed streams such as those that flow down from volcanic terrain in northernmost California and can survive drought much longer than snow-fed streams.

In the late 1970s, Moyle discovered that native fish in the Monterey Bay watershed recolonized their streams relatively quickly after a two-year drought. But today’s streams face greater ecological pressures, such as more dams and more non-native species competing for habitat.

Other challenges arise in the delta where the Sacramento and San Joaquin rivers meet, north-east of San Francisco. An invasive saltwater clam (Potamocorbula amurensis) has taken advantage of warming river waters and moved several kilometres upriver, says Janet Thompson, an aquatic ecologist with the US Geological Survey (USGS) in Menlo Park, California.

Potamocorbula out-competes a freshwater clam (Corbicula fluminea), and accumulates about four times as much of the element selenium from agricultural run-off and refineries as its freshwater cousin does. When endangered sturgeon feed on Potamocorbula, the fish consume much more selenium than is optimal. “That’s the biggest shift that we’ve seen that’s of environmental concern,” says Thompson. “These are the kinds of things that can have a lasting effect on a predator species.”

Teasing out the drought’s effects on terrestrial animals is tougher. Researchers have documented drops in various California bird populations this year, such as mallard ducks (Anas platyrynchos) and tricolor blackbirds (Agelaius tricolor). But many other factors — especially habitat loss — also come into play, so it becomes hard to isolate the effects of drought.

The drought’s effects on larger animals such as bears are also uncertain. Anecdotal reports suggest that more bears than usual are showing up closer to people this year, says Jason Holley, a wildlife biologist at the California Department of Fish and Wildlife in Rancho Cordova. Within the space of six weeks this spring, four black bears appeared along the Sacramento River corridor, much farther out of the mountains than normal. “Those sorts of calls definitely pique your interest,” says Holley, who thinks that dry conditions in the mountains might be pushing bears closer to populated areas.

The longest-lasting effect could be on California’s forests, including its iconic giant sequoias. The drought has handed forest ecologists an unplanned experiment, says Phillip van Mantgem, a forestry expert at the USGS in Arcata, California, who is speaking at the Sacramento meeting.

Researchers are gathering data to examine whether thinning of plots in the forest, in part to reduce fire risk, might help trees do better under drought. Tests may also help to reveal the main mechanisms by which drought kills different tree species, whether by interrupting the flow of water within the tree or by starving it. “I’m really curious to see how this turns out,” van Mantgem says.

There should be plenty of time to gather data. Climatologists expect an El Niño weather pattern to form in the Pacific this year, which usually brings more rain and snow to parts of California (see Nature 508, 20–21; 2014). But the pending El Niño looks to be weaker than first expected, and may not have much, if any, influence on ending the drought. Chances are that the state will remain dry well into 2015.

Access to water proves key factor in farmland value

Source: Kate Campbell; Ag Alert

With drought adding new constraints on the state’s water supplies and farmers and ranchers increasingly turning to groundwater to sustain food production, lawmakers now are contemplating bills requiring changes to how groundwater basins are managed. If adopted, opponents said, the bills have the potential to undermine food production, reduce agricultural land values and hamper the overall economy.

Two pieces of legislation were each amended twice last week and now have identical language, requiring assessment of impacts on local ecosystems from groundwater pumping. The measures will be heard in their respective Appropriations Committees this week. The California Farm Bureau Federation and other agricultural and water organizations oppose both measures.

Jack Rice, CFBF associate counsel, warned of unintended consequences from laws that are hastily passed and implemented.

“Figuring out how to improve groundwater management in California requires figuring out the best possible solution for a highly complex problem,” Rice said. “That doesn’t mean throwing legislation together and passing it before people even have a chance to understand the implications of how a new groundwater management framework will operate. Poorly conceived and executed changes to groundwater management would be very disruptive.”

Among the issues hanging in the balance, he said, are farm and ranch land values, which depend on property rights for access to groundwater supplies, particularly when surface water supplies are unreliable due to drought, plus regulatory and water-system constraints.

In summarizing current farm and ranch real estate trends, the California Chapter of the American Society of Farm Managers and Rural Appraisers concluded in its 2014 trends assessment that acute drought threatens many growers this year, and long-term water policy will have long-term ramifications on the farm and ranch sector.

In a presentation to agricultural land appraisers this spring, the association said “property in areas with threatened ground and surface water is at risk, but property in areas with good water will continue to be attractive.”

Rice said discussions about potential changes to groundwater management raise questions about the ability of affected property to sustain anticipated cash flow.

“Those kinds of uncertainties can have an impact on the value of underlying assets, such as land values, property improvements and equipment,” he said.

The Salinas Valley, which produces much of the nation’s fresh produce, is in a unique situation, according to Monterey County Farm Bureau Executive Director Norm Groot.

“We’ve been working for the past 60 years to manage our water resources—addressing everything from groundwater management and saltwater intrusion to surface supplies and flood control,” he said.

Because landowners have been engaged on many issues at the local level, Groot said, “we think another layer of regulation from the state will only hinder what we’re doing. It’s a hindrance we don’t need.”

Tony Toso, a Mariposa County rancher and professional farm and ranch land appraiser, said land appraisal values are based “on what has occurred in the rearview mirror,” but that how well water is managed at the local level has an impact on values.

“The market is going to start telling me as an appraiser what’s happening to land values in specific irrigation districts and groundwater basins based on reliability and quality of water supplies,” said Toso, who is a CFBF director.

“We do know groundwater is essential to ensuring a consistent agricultural land value,” he said. “Everyone knows that land without water isn’t worth much.”

Overall, appraisers said California farm and ranch land prices have held steady. However, rangeland without access to water has seen a decline in recent years.

Experts warned that not getting groundwater regulation right has the potential to strip some of California’s best farmland of its productive use and set off a decline in asset values.

“It’s hard to prove something that could happen in the future,” Toso said, “but if you don’t analyze water supply problems right, if regulations aren’t implemented right, if it’s turned into an emotional issue, then asset values could start heading for zero.”

Changes to groundwater management regulations could have a “huge” effect on local economies, said Tod Kimmelshue, a senior lender with Northern California Farm Credit, who explained that agricultural lenders always take into account water quantity and reliability for farm operations.

The question lenders need to determine, he said, is what is the highest and best use of a piece of land.

“Farmers need to be heavily involved in deciding who determines beneficial use,” said Kimmelshue, who is a past CFBF director. “It’s important for groundwater users to start monitoring how much water they’re using so they can document how much water they need for beneficial use.”

He said lenders are requiring increasingly more information on a property’s wells and access to groundwater, adding, “It’s a huge part of the collateral we consider when making individual lending decisions. But the impact of poorly designed groundwater management regulations could extend beyond affecting agricultural land values; there could be a ripple effect that moves through local economies from reduced property and business tax revenue and local jobs.”

A comparison: How California farms stack-up around the country

By Don Curlee; the Porterville Recorder

Counting the ways farming in California differs from farming in the rest of the country might result in some surprises, especially for proud Californians.

To begin with, farms in California are about 25 percent smaller on average than those in the rest of the country. The contrast between farming here and farming there is even more remarkable when you consider that the state’s smaller farms outpace those in the rest of the country by producing almost five times the dollar amount per acre. Of course, that means farmers in the Golden State receive more income than those elsewhere.

These characteristics of the country’s farm profile come from information collected in the 2012 Census of Agriculture, the latest every-five-years exercise conducted by the federal government. Comparing data from the most recent census with that from the 2007 effort reveals some memorable results.

Some of those results have been compiled by Emma Knoesen, a research associate and Rachael Goodhue, a professor of Agricultural Resource Economics (ARE) at the University of California, Davis. Their report was published in the May/June issue of Update, published by the Giannini Foundation of Agricultural Economics at Davis.

In the conclusion of their report they say: “(The census) indicates that California agriculture remains distinct from U. S. agriculture as a whole, although in both cases farms continue to grow larger in both acreage and market value of production.”

One of the report’s tables shows that almost a quarter of California farms are between one and nine acres, compared to only 11 percent of farms at that size elsewhere in the country. Another quarter of California farms are between 10 and 49 acres, not that different from the rest of the country, and 17 percent fall into that 50 to 179- acre bracket, opposed to 30 percent of farms that are outside the state.

A very telling statistic puts the number of California farms with 2,000 acres or more at 2,434, while the number of farms in the other 49 states with 2,000 acres or more is more than 82,000. Seems that fly-over country has some pretty big spreads, and it isn’t puny backyards where Texans raise their cattle.

Perhaps even more telling is the effect of California’s higher value crops, the vegetables, fruits and specialty commodities. The report says: “The average market value of production per acre of farmland in California was $1,667, compared to $289 in the United States as a whole.”

On average, California farms produced a market value of $547,510, about three times that of other U.S. farms, which averaged $187,097.

Production of high-value fruit and vegetable crops continued in California at about the same pace and in about the same places as reported in the 2007 census. Tree and vine crops dominated the Central Valley counties, and vegetables were the commodities of choice in coastal areas and in the Imperial Valley.

Imperial County registered a strong increase from 2007 to 2012 in the amount of land used to grow vegetables, from less than 69,000 acres in the earlier census to nearly 106,000 acres in 2012. The number of farms growing vegetables there increased as well, from 86 to 105.

Even though the number of California farms decreased from 2007 to 2012, the total market value of their production increased by a little more than 25 percent.

No question, farming is a winner in California and a significant contributor to the state’s economy. If overzealous legislators and social and environmental purists can control themselves enough to leave it alone the state’s different-but-better agriculture can continue to prosper and continue to help overcome world hunger.

Winegrapes: New acreage helps offset drought impacts

Source: Steve Adler; Ag Alert

Although per-acre yields may be down in some regions due to drought and other concerns, California farmers expect to produce another large winegrape crop this year, as a result of increased acreage. Winegrape harvest has started throughout California, primarily for early varieties of white grapes that are destined to become sparkling wines.

Government estimates issued last week placed California winegrape acreage at 570,000 acres in 2013, up from 508,000 the previous year. About 45,000 of the 2013 winegrape acres were classified as non-bearing.

With the harvest beginning in most areas from 10 days to two weeks earlier than usual, the biggest concern among growers is that many wineries do not yet appear prepared to receive the grapes.

“Being this early, I don’t believe the wineries were prepared to open on time, so right out of the gate we had some quality issues because of early ripeness and delays on the winery side,” Tulare County winegrape grower JR Shannon said. “We’ve barely been picking for two weeks and it is already showing signs that the winery tanks are still full from last year and they aren’t very eager to get grapes in right away.”

Noting that harvest will continue for several more weeks, Shannon said many wineries haven’t even opened yet.

“The early signs are that it is going to be a long, non-grower-friendly season and the wineries are showing no excitement about anything except pinot grigio. We spent a lot of money planting these new vineyards for them and they are not cooperating in getting the grapes into the wineries,” he said.

That view was supported by Nat DiBuduo, president and CEO of Allied Grape Growers in Fresno, who said there is real concern among growers who don’t have contracts with wineries.

“We are getting reports of some of the larger wineries that have decided to bottle as needed, which means the tanks are full. We know the 2012 crop and the 2013 crop were big, and what that has created is that they aren’t buying any more grapes than what has been contracted for. And there are a lot of grapes that aren’t contracted,” he said.

DiBuduo said the vast majority of grapes are under long-term contracts, but there are some that don’t have contracts and growers in that situation are just waiting for wineries to start buying them.

“I hope the wineries start to realize that this is going to be a lighter crop. They will all honor their contracts, but I am hopeful that they will recognize the smaller crop and buy these other grapes. The speculation is that some of these wineries will come out with lower prices when all of these growers are in panic mode,” he said.

In Lodi, winegrape grower Joe Valente of Kautz Farms said harvest at his vineyards would begin this week, putting it 10 days earlier than usual.

“It is probably one of the earliest or second-to-the-earliest starts that I have seen here in Lodi in the past 35 years. We are starting this week, but it all depends on the sugars. Ideally, once we get started we can keep going, but it is all dictated by the sugars,” he said.

Valente also expressed concern about a potential shortage of tank space for this year’s grapes.

“The last two years were large crops, and how empty the tanks are going into harvest will dictate how much we will be able to pick. It depends on the varietals that are in demand. They will find room in the tanks for certain varieties that are in demand,” he said.

On the South Coast, grape grower Jeff Frey of Santa Maria said he has heard talk of tank shortages, but at this point it doesn’t appear to be an issue in his area. A bigger issue for coastal growers is the ongoing drought, he said.

“The situation concerning drought on the South Coast depends on where you are at. We haven’t had any rain to speak of, but growers who were able to irrigate through the winter are looking pretty good. We have a pretty good crop set and we will start harvesting next week, which is very early for us. I have a few vineyards that are out of the periphery that have wells that are going dry and there isn’t much water, so those yields will be down,” he said.

In the Paso Robles area, grower Neil Roberts of Templeton said he is very pleased with the way winegrapes developed this year.

“The crop looks average in size, which is probably a good thing, and the quality looks tremendous,” Roberts said. “We’ve been OK with water. Some of the shallower wells have had some issues, but overall there weren’t any problems. If everything goes well, we should be done by the end of October.”

DiBuduo said the drought is having an impact in the San Joaquin Valley as well. The quality of the grapes being produced is fine and sugar levels are good, but the berries and the bunches are smaller, he said.

“It appears that the overall crop will be lighter than last year and a lot of it has to do with the drought. Growers have tried to maintain the vines and keep them as fresh as possible, but we are hearing from all over the place about growers’ pumps going out and it has been taking several weeks for the pump repair people to take care of the problem,” he said.

Shannon, too, has been having problems with lack of water. He said he has been forced to pay up to $1,200 an acre-foot for water that in a normal year costs $60.

“It is kind of salt in the wound right now with all the other issues we have been dealing with,” he said. “Hopefully the groundwater will last another three months.”

Shannon said he has three or four wells out of commission waiting for pump repair, calling 2014 “the toughest year in my experience.”

Valente said that so far this season, he hasn’t had any problem with wells.

“Our concern is groundwater legislation and what that might mean to us. We keep hearing that farmers aren’t managing our groundwater, and I truly believe that the state and federal governments aren’t managing our surface water,” he said.

Understanding California’s Groundwater

California’s Groundwater Is in Crisis

Source: Janny Choy and Geoff McGhee; Water in the West

California’s groundwater is back in the spotlight. Largely invisible, lightly regulated and used by 85% of California’s population and much of the state’s $45 billion agriculture industry, groundwater is a crucial reserve that helps stave off catastrophe during drought periods like we’ve experienced over the past three years.

Unheralded, Underegulated and Overused, California’s Groundwater Is in Crisis

But after more than a century of unregulated use, California’s groundwater is in crisis – and with it the state’s hydrologic safety net. This carries profound economic, environmental, and infrastructure implications. How did it come to this, and what do we do now?

6 Million Californians Rely on Groundwater

Over 6 million Californians rely solely or primarily on groundwater for their water supply. Many of them reside in towns and cities in the Central Valley and along the Central California coast, where communities generally have limited local surface water options or don’t have the ability to finance other water supply sources.

For Others, Groundwater Complements the Surface Water Supply

Generally, though, groundwater is used alongside surface water to meet the state’s needs, which range from urban and industrial uses to irrigating roughly half the fruits and vegetables grown in the United States.

In normal and wet years, groundwater provides 30 to 40% of the water supply. It supplements surface water that is collected from snowmelt and rainfall then is stored and conveyed by a vast system of state and federal dams, reservoirs, and aqueducts.

During droughts, surface water availability can be sharply reduced, leaving water users to pump water from local wells. At times like these, groundwater can surge closer to 60% of water used statewide, and even higher in agricultural areas like the Central Valley.

When Rain and Snow Don’t Fall, Groundwater Prevents Disaster

This year, the third consecutive year of an extreme and extensive drought, state officials have warned that little or no surface water will be made available to most consumers. In turn, water providers are advising large users to pump their own groundwater.

As bad as this drought is, it is not uncommon. Droughts are a part of life in California, as anyone who has lived here long enough knows. But what most may not know is that groundwater has been getting us through droughts, including the last big one in the 1970s, and it is getting us through the one today.

In fact, 5 million acre feet of additional groundwater will be pumped in the Central Valley alone to make up for the 6.5 million acre feet in surface water reductions for agriculture in 2014. Even so, the economic loss for the Central Valley from this drought is expected to be $1.7 billion.

By Overusing Groundwater Today, We Are Living Off Our ‘Savings’

Writers often turn to financial metaphors to explain the importance of groundwater. As Tom Philpott of Mother Jones magazine wrote recently, “To live off surface water is to live off your paycheck … To rely on groundwater, though, is to live off of savings.”

Another metaphor frequently applied to groundwater is that of mining. In fact, “groundwater mining” is exactly what experts call nonrenewable groundwater use, where farmers “mine” water to grow almonds, alfalfa or grapes. You could even say they are “mining” those commodities themselves.

Recommendations for Groundwater Reform

Through numerous hearings, workshops, and consultations with experts and interest groups, recommendations by groups such as the California Water Foundation are coalescing around the concept of local groundwater management with the state serving as a backstop authority if local action has not occurred or is insufficient.

Next steps might include creating and empowering local groundwater management entities; requiring groundwater management plans; and defining the state’s role for assistance, oversight, enforcement and funding. Read more in the California Water Foundation’s report with recommendations for sustainable groundwater management.

Caifornia drought transforms global food

Source: Jeannette E. Warnert; ANR News Blog

Due to the California drought and what scientists believe will be a drier future, the state’s farmers will likely move away from commodity crops to focus on high-value products like almonds, pistachios and wine grapes, according to Richard Howitt, agricultural economist at UC Davis. Howitt was used as a source in a lengthy story on Bloomberg.com about repercussions worldwide of the three-year dry spell in the Golden State.

Another source was Dan Sumner, director of the UC Agricultural Issues Center. He said shifts in California ag trends reverberate globally.

“It’s a really big deal,” Sumner said. “Some crops simply grow better here than anyplace else, and our location gives us access to markets you don’t have elsewhere.”

California is the United States’ top dairy producer and grows half of the country’s fruit. In 2012, almonds became the state’s second-most valuable ag crop. The Washington Post reported that in the U.S., almond consumption has grown by more than 220 percent since 2005. In the late 2010s, almonds surpassed the long-running nut leader peanuts (not including peanut butter) in per capita consumption.

The Bloomberg article opened with the story the Fred Starrh‘s family farm in Kern County. The Starrh family was a prominent cotton grower for more than 70 years. The shifting global market and rising water prices prompted the family to replace more of their cotton plants with almonds.

“I can’t pay $1,000 an acre-foot (of water) to grow cotton,” said Starrh, 85.

California grows four-fifths of the world’s almonds, the Bloomberg story said, using enough water to meet the needs of 75 percent of the state’s population. An advocate for bigger water supplies for cities suggests in the story that farmers should be profitable, but it shouldn’t come at the expense of urban water ratepayers.

Pistachios May Benefit Heart Health in Adults with Type 2 Diabetes

Stress Tests Show Blood Vessels More Relaxed and Open in Published Study

In the Journal of the American Heart Association

It was announced TODAY, that a healthy diet including pistachios may benefit heart health in adults with Type 2 diabetes, according to a Pennsylvania State University study published online in the Journal of the American Heart Association.

Adults with well-controlled type 2 diabetes, who were otherwise healthy, participated in a randomized, controlled clinical study and showed a more positive response to stress following a diet containing pistachios than when following a standard low-fat control diet. The healthy diet, which included two servings daily of pistachios, significantly reduced peripheral vascular resistance, increased cardiac output, improved some measure of heart rate variability and importantly reduced systolic ambulatory blood pressure.

Dr. Sheila G. West, principal investigator and professor of biobehavioral health and nutritional sciences at Penn State, and her colleagues reported similar beneficial results in a study of adults with elevated LDL cholesterol and stress, published two years ago. Increasingly it has been found that pistachios, both salted and unsalted, contribute to a heart-healthy diet in high-risk groups. Pistachios contain good fats and fiber, potassium and magnesium.

In this Penn State study, test diets included a low-fat control diet with high carbohydrate snacks (27 percent fat and 7 percent saturated fat) compared to a moderate-fat diet (33 percent fat and 7 percent saturated fat) that included 3 ounces, or 20 percent of the calories, from pistachios. The servings consisted of equal amounts of salted and unsalted nuts. All meals were provided to the 30 participants, an equal number of men and women, ages 40-74. The calorie levels for the subjects were based on the Harris-Benedict equation so that calories and body weight did not change throughout the study.

A two-week run-in period on a typical western diet preceded the first test diet. Participants discontinued all dietary supplements at least two weeks prior to the beginning of the study. These adults were then administered each test diet for four weeks, separated by two-week compliance breaks, randomized and in a counterbalanced order. At the end of each diet period, including the run-in weeks, participants underwent comprehensive testing.

Researchers measured blood pressure and total peripheral vascular resistance, both at rest and during stress tests, which consisted of holding a hand in ice water for more than two minutes and a difficult math challenge. “After the pistachio diet, blood vessels remained more relaxed and open during the stress tests,” confirmed Dr. West. She continued, “The pistachio diet reduced their bodies’ responses to stress.”

Twenty-four hour systolic blood pressure was significantly lower following the pistachio diet compared to the control diet, with the largest reduction observed during sleep. According to Dr. Kathryn Sauder, a co-investigator who conducted the measurements, “This finding was important because individuals who do not display a dip in blood pressure during sleep may be more likely to experience a cardiovascular event.”

Dr. West concluded, “A moderate-fat diet containing pistachios may be an effective intervention to reduce cardiovascular risk in persons with type 2 diabetes.” In spite of being obese and having a diabetes diagnosis, participants had normal blood pressure and only moderate dyslipidemia. However, even in relatively healthy diabetics, there is room for improvement. The results of this study suggest that a healthy diet containing pistachios can add to the protective effects of drugs for persons with type 2 diabetes.

The researchers suggested future studies should enroll larger samples, include ambulatory blood pressure as a primary outcome and test the effectiveness of pistachio consumption on cardiovascular risk factors in a free-living setting.

The study was supported by the American Pistachio Growers, Fresno, Calif., with partial support from the National Institutes of Health-supported Clinical Research Center at Pennsylvania State University.

Pistachio Facts

Pistachios are nutrient-rich and full of antioxidants, vitamins, protein and fiber. A one-ounce serving of pistachios equals 49 nuts, more per serving than any other snack nut. They are cholesterol free and contain just 1.5 grams of saturated fat and 12.5 grams of fat per serving, the majority of which comes from monounsaturated and polyunsaturated fat. In addition, they contain a significant amount of potassium, 300mg, and 3g fiber per serving.
