The legalization of marijuana for recreational use in California has encouraged growers to expand plantings of the lucrative crop. Like any plant, cannabis requires water to grow. A new study from the Cannabis Research Center at UC Berkeley examined where cannabis growers in California are getting water for their crops, highlighting significant gaps in cannabis cultivation policy.
Environmental advocates have expressed concern that cannabis farms are diverting water from rivers and streams, which could harm fish and other wildlife.
The researchers studied water use in 11 of the state's top cannabis-producing counties – Humboldt, Lake, Mendocino, Monterey, Nevada, San Luis Obispo, Santa Barbara, Santa Cruz, Sonoma, Trinity, and Yolo.
Using California state cannabis permitting data, the researchers found that cannabis farms rely primarily on groundwater wells, not streams, for their irrigation needs. But pumping groundwater could also have an undesirable effect on wildlife.
“Wells drilled near streams in upland watersheds have the potential to cause rapid streamflow depletion similar to direct surface water diversions,” said co-author Ted Grantham, UC Cooperative Extension specialist and co-director of the Cannabis Research Center.
The Sustainable Groundwater Management Act, or SGMA, enacted in 2014, is designed to prevent overdraft of groundwater and protect water quality and supplies for agriculture, residents, fish and other wildlife.
But according to Grantham, “Most of the cannabis farms fall outside of the groundwater basins regulated under SGMA, so well use represents an important, but largely unregulated threat to streams in the region."
The researchers found that well use by cannabis farms is common statewide, exceeding 75% among farms that have permits to grow in nine of the 11 top cannabis-producing counties. In eight of the 11 counties, more than one-quarter of farms using wells are located outside of groundwater basins subject to state groundwater use regulations. Farms growing larger acreages of cannabis pumped more groundwater for irrigation, while farms with on-farm streams or located in areas that receive more rainfall were less reliant on wells.
The study relied on water-source data only for cannabis farms that have state permits to grow.
Based on models, the researchers estimate the majority (60%) of unregulated Northern California cannabis farms in Humboldt and Mendocino counties are likely to use groundwater wells if they follow the same patterns as the regulated industry.
“Our results suggest that proactive steps be taken to address groundwater use in cannabis regulations in California and call for further research into the effects of groundwater use on streamflow, especially outside of large groundwater basins,” write the authors.
The paper, “Cannabis farms in California rely on wells outside of regulated groundwater basins,” by Christopher Dillis, Van Butsic, Jennifer Carah, Samuel C. Zipper and Grantham is published in Environmental Research Communications at https://doi.org/10.1088/2515-7620/ac1124.
As California strives to recover from the pandemic-induced economic slump, Keith Taylor is taking an unconventional approach to economic development. In the world's sixth biggest economy, where do you start? Taylor, who was hired in 2017 as UC Cooperative Extension's sole specialist in community economic development, started by tackling a couple of the state's thorniest sectors: cannabis and utilities.
Participatory research in Mendocino County
In 2016, the passage of Prop. 64 legalizing recreational cannabis ushered in an era of both opportunity and headaches for Mendocino County growers. The county's permitting program has been the source of significant confusion and debate: Between 800 and 1,100 growers have received county permits, but many have not been able to obtain permanent state licenses because of a lack of clarity around the county process and compliance with the California Environmental Quality Act. The burden of uncertainty is one reason why only a fraction of Mendocino growers have pursued licenses, says Taylor, who is based in the Department of Human & Community Development at UC Davis.
While these regulatory battles play out, Taylor says better economic coordination between small growers could buffer them against large capital interests moving into cannabis. Virginia-based Altria, the parent company of Philip Morris USA, is investing in cannabis and filing patents for cannabis-specific vaporizers. Individual legacy growers have the crop experience and market share, Taylor says, but don't have shared institutions through which they can exercise collective power — especially down the value chain in processing, distribution and consumer technology. Taylor believes that creating a small farmer-centric system will involve the creation of more interest groups, associations or cooperatives.
“For too long in agricultural and rural communities, we've encouraged people to do things alone,” Taylor said in an October 2020 presentation to the UC Davis Cannabis and Hemp Research Forums. However, if you look at parts of the world where rural economies do very well, they work together.”
With help from a Cannabis and Hemp Research Center grant, Taylor has been working on a wide-ranging participatory action research project in Mendocino County. Taylor's team — comprised of two faculty members, one post-doctoral researcher, and two student researchers — is producing research publications, policy recommendations and public events about ways that the emerging cannabis industry can support high-quality livelihoods and environments for county residents.
“The more we make folks aware of these good actors, the more likely we are to get challenges to the incumbents in terms of climate mitigation and economic developments,” Taylor said.
West Business Development Center, Economic Development & Financing Corporation and Mendocino County Supervisor John Haschak have been allies in the process so far. Haschak says Taylor brings valuable knowledge, resources and networks to bear on local challenges.
“There's a lot of opportunity for doing this whole new industry in a new way, and I think that's what Dr. Taylor sees too,” Haschak said. “There's a lot of potential here for structuring the industry along the lines of what our community values already are.”
As Taylor's team releases their findings, they intend to host forums at the Hopland Research and Extension Center to help the county harness the legal cannabis sector for economic impact.
Power to the people
Shortly after arriving at UC Davis from Illinois, Taylor published a book about the benefits of community ownership of wind energy in the Midwest. The turmoil surrounding California's largest utility, Pacific Gas & Electric, could have been ripped from the pages of his research. PG&E equipment has ignited half of California's most destructive fires since 2015, and experts pin much of the blame on the company's lack of investment in the grid.
In the months following the 2018 Camp Fire, which burned an area roughly the size of Chicago andkilled85 people, Taylor was one of the first advocates to propose converting PG&E into a user-owned nonprofit cooperative. This conversion would remove the extractive role of investors and give customers a voice in big-picture decisions about the company, Taylor wrote in an op-ed pushing the idea of customer ownership in The Mercury News in February 2019. By December, more than 100 elected officials across 10 counties endorsed the idea. The federal bankruptcy judge overseeing PG&E's case did not endorse the plan, although it's still possible for the state to take over the company under certain conditions. Other attempts to gain local control of PG&E's grid — including San Francisco's bid to buy the city's power lines from the company — also stalled.
Taylor isn't discouraged. He is working closely with the Golden State Power Cooperative, an association of the state's three community-owned electric utility co-ops, to push forward what he calls a “Rural Electrification Act for California broadband.” Taylor often references this New Deal-era law that gave federal loans to rural communities seeking to expand the electrical grid to their area. The act gave rise to the nation's more than 900 electric cooperatives today, including the three in California. With their help, Taylor sees opportunity in legislation or programs that would catalyze community-initiated, community-owned internet services. Plumas-Sierra Rural Electric Cooperative is already bringing broadband to the rough terrain of its mountain customers.
“When you first set foot in California and are exposed to the giant that is PG&E and their influence over policy, you think that it's an obstacle that's too difficult to overcome,” Taylor said. He tries to elevate the visibility of people who are making inroads and recently featured Kevin Short in a webinar about community economic-development innovations.
Short is the general manager of Anza Electric Cooperative in California's high desert and current board president of the Golden State Power Cooperative. He said there are “tremendous opportunities” in the idea of growing cooperative broadband entities, especially with the attention on infrastructure at the state and federal levels. Short said the effort will take some creativity and willingness to depart from existing models: “The old saying among us here is if you've seen one co-op, you've seen one co-op, because it's going to be different everywhere you go.”
In both of these areas — cannabis and utilities — Taylor says his role is networker and facilitator. As the only economic development specialist at UC Agriculture and Natural Resources, he spends a lot of time researching and meeting people to understand where his efforts can be the most strategic. “In order to scale, I've got to go small, root and build and be comfortable with that process,” he said.
Small works for now, but Taylor remembers an associate dean telling him, “You've got a great job, now make it work for 40 million Californians.”
Several scientists affiliated with the University of California Agriculture and Natural Resources have received grants from the California Bureau of Cannabis Control.

The Camp Fire started on federal land. This rule would make PG&E clean up its power lines
(Sac Bee) Emily Cadei, Sept. 30
…“In California, it is fairly clear that PG&E did not keep an up-to-date inventory and accomplishment schedule on vegetation clearance on all of their power lines,” William Stewart, director of the Berkeley Forests program at UC Berkeley, said in an email. “ I think the Forest Service wants to make sure that they are sending the same signals to their staff and partners that judges are now sending to PG&E — do proper power line clearance or some entity (or entities) is going to be on the hook for billions of dollars of damages.”
UC ANR Takes In-Depth Look at the Cannabis Industry
(AgNet West) Brian German, Sept. 27
Following the passage of Proposition 64 which legalized recreational cannabis, there was significant excitement surrounding the potential for a legal and regulated cannabis industry in California. However, the development of the guidelines for cannabis cultivation has undergone significant delays as the state works to build infrastructure for a commodity which is still federally prohibited. The July-December 2019 issue of the research publication from UC Agriculture and Natural Resources, California Agriculture, highlights multiple components for the development of legal cannabis in California. The special issue details the history of cannabis in the state, as well as some of the research being conducted on various aspects of cannabis.
Industry advocates weigh in on California's proposed rodenticide ban

…Dr. Niamh Quinn, Human-Wildlife Interactions Advisor University of California Cooperative Extension, Irvine, Calif.
There have been several iterations of bills in California over the past four years. Most of them are targeting anticoagulant rodenticides, although they morphed along the way; they started with all of the rodenticides, and now they're particularly focused on SGARs. As it was written, AB 1788 proposed serious restrictions on the use of SGARs, with some fairly limited applications throughout the state. In essence, it would have been an almost total ban of SGARs for structural pest control.
California farm region faces furry new threat: swamp rodents

…Damage to the region's soil or water infrastructure would be devastating to the economy and diet.
“It would mean no more sushi because the alternative would be to buy rice from Japan or Korea, where the price is five times higher,” said Daniel Sumner, director of the Agricultural Issues Center at the University of California-Davis. “Kiss off carrots, or live without table grapes in the summertime.”
New California lab seeks cure to deadly citrus disease
(Washington Post) Amy Taxin, Sept. 26
RIVERSIDE, Calif. — In a lab southeast of Los Angeles, researchers are opening a new front in the yearslong battle against a tiny pest that has wreaked havoc on citrus groves around the world.
California citrus growers and packers and the University of California, Riverside on Thursday marked the opening of an $8 million lab dedicated to finding a solution to the tree-killing disease known as Huanglongbing that has ravaged groves in Florida, Brazil and China.
…Georgios Vidalakis, director of the Citrus Clonal Protection Program at University of California, Riverside, said citrus boomed in California in the late 1800s. In the decades that followed, researchers in Riverside started a citrus breeding program, which helped develop new varieties, and a citrus collection, which now has more than 1,000 kinds of trees, he said.
Vidalakis, a plant pathologist, oversees a program aimed at ensuring trees don't introduce diseases into the region. But without the ability to study the illness, research was hampered, he said, until experts and growers joined together to build the lab.
“This disease is like nothing we have ever faced as plant pathologists,” he said. “We need all hands on deck.”
These Big Plans to Protect California Homes From Wildfire Fell Short in the Legislature
(KQED) Lauren Sommer, Sept. 26
…While Cal Fire has a goal of inspecting 33 percent of structures in its jurisdiction each year, a KQED investigation found the agency only did half that in 2018. In some parts of the state, only 6 percent of homes in risky areas were inspected.
“It's becomes really clear that our defensible space has been insufficient to protect homes from embers,” said Yana Valachovic, a fire expert with UC Cooperative Extension. “What's immediately adjacent to a structure affects the probability of a structure's survival.”
…“The science has been clear for quite a while, but it's been slow to incorporate into codes, standards and practices,” said Valachovic.
… “There's no single solution that's going to solve the fire problem,” said Valachovic. “It takes an all-hands-on-deck approach.”
Lindcove dedicates conference center to Exeter man
(Sun Gazette) Sept. 25
A late Exeter man who donated most of his fortune to local agriculture and educational institutions, will soon have his name affixed to University of California research facility.
The Lindcove Research and Extension Center, part of the UC Agriculture and Natural Resources system, will rename its conference center after the late Ray Copeland. The Ray Copeland Citrus Center will be dedicated during the Lindcove Citrus Gala on Oct. 4.

UC Cooperative Extension Survey Results on Cannabis Cultivation
(Sierra Sun Times) Jeannette Warnert (news release) Sept. 23
A UC Cooperative Extension survey of California registered and unregistered marijuana growers will help researchers, policy makers and the public better understand growing practices since cannabis sales, possession and cultivation first became legal for recreational use.
“This survey is a starting point from which UC scientists could build research and extension programs, if possible in the future,” said lead author Houston Wilson, UC Cooperative Extension specialist with UC Riverside. A report on the survey results was published in the July-December 2019 issue of California Agriculture journal, the research publication of UC Agriculture and Natural Resources.
In a Race Against the Sun, Growers Try to Outsmart Climate Change
(New York Times) Marla Cone, Sept. 21
…“We can't continue to do the exact same thing we are doing now,” said Katherine Jarvis-Shean, a University of California researcher who advises orchardists on how to cope with climate change. “There are a lot of solutions to the anticipated problems. We just have to get on top of them, testing them and making them available to growers.”
…“For the most part, the world gets fed by row crops,” said Pat J. Brown, an associate professor at the University of California-Davis, referring to wheat, corn and other staples. “But a lot of the stuff that makes life really worth living comes from trees. Think of the world without chocolate or wine or coffee.”
…The Agriculture Department has repositories that store genetic material from every type of tree on earth. Dan Parfitt, a now-retired University of California-Davis plant geneticist, started breeding pistachios using tissue from those repositories more than 30 years ago in an effort to help growers economize their harvest.
As the climate changed, Dr. Parfitt got the idea to plant a few hundred of the trees in the California desert. “The Coachella Valley is the closest to the warmer winters and drier conditions that we will see in the San Joaquin Valley in 20 to 30 years,” he said.
Cannabis findings presented in Mendocino County by Berkeley's Cannabis Research Center
(Ukiah Daily Journal) Carole Brodsky, Sept. 21
One knows times have changed when California Agriculture, the official magazine for the University of California's Agriculture and Natural Resources Division features High Times-worthy photos of cannabis flowers on the front cover. In fact, cannabis is the sole focus of the quarterly, peer-reviewed publication.
Since 2017, the University of California's Cannabis Research Center (CRC) has been hard at work. A 12-person research team, supported by 50 undergraduates, has been conducting groundbreaking research, some of which was presented to the public on Sept. 15 at the Hopland Research and Extension Center.
Team members presented their findings, including the results of a cannabis production survey, which was taken by 350 California cannabis farmers largely located in the Emerald Triangle region. Dr. Van Butsic, assistant cooperative extension specialist and co-director of the Cannabis Research Center, acted as presenter for the event.
Butte County suffers two more human cases of West Nile
(Chico Enterprise Record) Brody Fernandez, Sept. 20
…Maurice Pitesky, is a researcher medical professional for the Veterinary Medicine Extension at the UC Davis School of Veterinary Medicine. Pitesky specializes in poultry health and food safety epidemiology — the study of diseases and large populations.
“The reason chickens are ‘sentinels', are because they don't really get sick,” Pitesky said. “Chickens are the canaries in the coal mine for the West Nile virus. We use them to determine if certain areas contain infected mosquitoes and if they've contracted the virus themselves. It's also a good way to put chickens in strategic places and check to see if they are producing the appropriate antibodies to the virus. From a preventative health perspective, they do serve a beneficial service.”
Chickens can not transmit the virus, they are only carriers, Pitesky said.
A tiny beetle has decimated hundreds of SoCal trees. Now experts are worried about Sacramento
(Sac Bee) Michael Finch II, Sept. 19
…The shot hole borer is not a strong flier so it's unlikely to move far on its own. It can, however, move faster when hiding in firewood and other green waste or landscaping equipment, said Akif Eskalen, a plant pathologist and professor at UC Davis.
Eskalen is one of many investigators looking for ways to naturally eradicate the beetle. Eskalen's work focuses on using native plants, but there is an ongoing trial with pesticides and another using natural predators. The studies, he said, “may take several years to complete.”
… Once inside a tree, the female produces offspring that mate with each other when they grow up and the death-dealing cycle repeats. This sequence happens as many as four times a year, or more if the weather is hotter, said Beatriz Nobua-Behrmann, a researcher studying the insect for the UC Cooperative Extension in Irvine.
They're believed to have arrived in wood packing materials made with infested wood from Taiwan and Vietnam, she said. Climate change could make it worse since the beetle thrives in warm weather. Its reproductive cycle accelerates as the temperature rises.
“Knowing that they can travel in wood or in green waste or in equipment that makes it a little bit more dangerous,” Nobua-Behrmann said. “It could easily make it to the northern counties with people moving firewood because they find it for cheap or for free.”
CBD oil price likely factor in $100 million payoff predicted for Ventura County hemp crop
Kathleen Wilson, Ventura County Star, Sept. 18
…More than 25,000 products can be made from industrial hemp, said Oli Bachie, a UC Cooperative Extension farm adviser in Imperial County who is studying hemp production. The plant can be used for fiber, feed, textiles and oils, but most if not all of the strains of hemp being planted in the county are for CBD, apparently because of the large profits that are expected.
Bachie would not be surprised to see that happen around the state.
"There is a huge interest in this because people want to grab the first economic benefit out of it," Bachie said.
Federal Government Approves Release Of Non-Native Weevil In California To Combat Invasive Thistle
(CapRadio) Drew Sandsor, Sept 18
…The U.S. Department of Agriculture said Tuesday it will permit use of the weevil native to Europe and western Asia to control yellow starthistle, which is from the same areas.
Brad Hanson, UC Cooperative Extension weed specialist at UC Davis, says yellow starthistle thrives in part because of its prickly spines.
"So it's not very palatable to any livestock, especially once it's started to flower, and it's toxic to horses. So often times the other grasses and more palatable plants are grazed and the starthistle persists and is sort of the only thing left,” he said.
California farms, ranches strive to adapt as climate warms - it's a matter of survival
(San Francisco Chronicle) Peter Fimrite, Sept 18
…Josué Medellín-Azuara, the associate director of the UC Agricultural Issues Center at UC Merced, said the biggest issue will be irrigation. Decreases in the Sierra snowpack mean less melting in the summer, so more rainwater will need to be stored in the winter. Hotter temperatures would also mean crops and orchards will retain less moisture.
“Plants may actually lose water more quickly because of the heat, so they may actually need more water than they need now to survive,” Medellín-Azuara said. This at a time when California is expected to experience more droughts.
…Frank Mitloehner, a professor in the UC Davis animal science department, said that is why sensors are being installed to monitor water use, and more ranchers are adopting regenerative farming and grazing techniques that ensure the land sequesters more carbon than it emits.
Drought tolerant crop being studied in the Valley
(ABC 30) Cristina Davies, Sept. 17
Big research is happening at the Kearney Agriculture and Extension Center in Fresno County.
Sorghum, a crop that looks similar to corn, is under a microscope.
Jeff Dahlberg, director of the center, said that sorghum is very drought tolerant.
"What we are looking for is the mechanism behind the drought tolerance in sorghum and if we can elucidate the genetics behind that, what we believe is we can use those genetics to see if the genetics in corn, or in rice, or in wheat," he said.
UC Pot Researchers Working with 'Gray Literature'
(East Bay Express) Dan Mitchell, Sept. 17
… The problem was brought into sharp relief last week when the Cannabis Research Center at UC Berkeley made its first formal presentation of the work that it's been doing. The center began operating at the beginning of the year to "promote interdisciplinary scholarship on the social and environmental dimensions of cannabis production." Every one of the five researchers who spoke during the presentation addressed the often-ridiculous restrictions under which they still operate. As Chronic Town reported recently, researchers in public universities all over the state aren't even allowed to be around pot plants, thanks to the federal ban — a mighty hurdle for people studying health effects, cultivation methods, pest-management techniques, and the like.
"It's a tricky problem," observed center Co-Director Van Butsic, an adjunct professor who specializes in land use. "We don't want our researchers to stay in the academy."

Sept. 18 meeting to explore prescribed burning
(Taft Midway Driller) Sept. 17
The SRWC's meeting will begin with an introduction from Etna Fire Chief Alan Kramer, after which Lenya Quinn-Davidson and Jeffery Stackhouse, advisors with UC Cooperative Extension and co-founders of the Humboldt County Prescribed Burn Association, will share the story of how their PBA got started two years ago. They'll talk about their PBA's work – more than a thousand acres of prescribed fire through 18 different projects – and they'll talk more generally about options for prescribed fire on private lands, permitting and regulations, project costs, and the benefits of prescribed fire on rangelands, forests, and woodlands.
Legalization of cannabis in California changes the dynamics of competing industries
Humboldt County has long been known for marijuana production. Over the last decade, the North Coast's Emerald Triangle – Humboldt, Mendocino and Trinity counties – have experienced a large influx of growers moving to the area to get into the cannabis business.
The greatest expansion of cannabis cultivation occurred within the remote corners of these counties.
“Forested and woodland parcels became valued, not for timber or ranching, but for their capacity to support cannabis operations,” said Yana Valachovic, UC Cooperative Extension director and forest advisor in Humboldt County. “Land prices skyrocketed and a whole wave of newcomers surrounded ‘traditional' producers of forest products and beef. The nearly exponential growth of the cannabis industry has been a shock to some and there has been a steady discussion of social, economic and environmental concerns.”
Of the 71 landowners responding to the survey, 18% said they had grown cannabis on their property and 40% said they had indirectly profited by trucking or operating heavy equipment for the cannabis industry. About half of the landowners didn't indicate whether they had or had not grown cannabis.
While the burgeoning cannabis grows have brought jobs to the economically challenged county, over 60% of the landowners agreed that cannabis had contributed to labor costs, 57% agreed it had negatively affected their livestock operations and the majority reported negative impacts to their property.
“Fences have been wrecked, roads damaged, and stream water theft,” wrote one rancher.
Since cannabis has become legal in California, most landowners (64%) have maintained their views on the industry. Yet, Valachovic and her colleagues are interested in seeing how this rural community adapts to protect its environmental health and economic prosperity.
“It's not news that ranchers can have issues with cannabis farmers, but the evolving perspective is what most excites me about this survey,” she said. “The cannabis industry is very dynamic and has experienced rapid expansion, price highs and lows, and an evolving public policy discussion trying to keep up with the changes. The results of this survey reflect opinions from 2018 and with the inclusion of hemp or low THC cannabis, perspectives will continue to evolve.”
The study was conducted by Valachovic, UC Cooperative Extension advisors Lenya Quinn-Davidson and Jeffery Stackhouse, and UC Cooperative Extension specialist Van Butsic in the Department of Environmental Policy Management at UC Berkeley.
The authors concluded that while public policy will not solve all social behaviors and competing industry needs, land-use policy can help mediate land-use conflicts and zoning to support new economic opportunities as well as existing multigenerational businesses.
“Humboldt has been at the forefront of these issues for decades and perhaps the lessons learned here can be helpful for other communities,” Valachovic said.
