Support Your Local Bee Keepers: how you can do your part

The humming sound of busy honeybees filled the fall air, darting back and forth as I followed longtime beekeeper Randy Oliver around his bee yard. I was there to learn about a new issue for local beekeepers. Oliver explained that local honeybee colonies have been robbed of their honey in places they have been kept year-after-year for several decades. Robbed?? Yes, by other honeybees, from hives from other parts of California. In the last couple years, numerous out-of-area hives have been placed in close proximity to local hives. Oliver, along with local beekeepers, presented a draft proposal to the Nevada County Ag Advisory Commission, which recommended an emergency beekeeping ordinance to county supervisors.

Oliver explained that the proposal calls for a minimum of a 2-mile radius around each existing apiary location and a 45-hive maximum in each location. All bee hives in Nevada County must be registered by the Ag Commissioner in January each year. This ordinance is designed to provide the resources and “teeth” to protect local bees and their food sources. Put in rancher terms, imagine that you had your cattle on pasture, someone saw your cattle grazing and decided to dump off 100 cows in the same pasture because it looked like a good food source.  “This is beekeepers regulating themselves” said Oliver. The ordinance would not cost taxpayers and is funded by beekeepers themselves. Hobby beekeepers would be exempt from the registration fees and existing hives would be grandfathered in. Another issue with having bee colonies in close proximity is the potential for infection and mite drift into hives. Oliver explained the dangers of reintroducing a bacterial disease called American foulbrood that is nearly eradicated in Nevada County. This issue may also be of concern in Placer County.

So what does this have to do with local farmers and ranchers? If someone asks permission to put honeybee hives on your land, or leaves a note on your gate, contact your Nevada County Beekeepers Association or search  “Honey” on the Placer Grown website to find local beekeepers.

A report released in March by the National Agricultural Statistics Service (NASS) stated that California produced 13,735,000 pounds of honey in 2017, worth more than $28.5 million dollars. Beekeeping is an important agricultural activity in this area. Hive rentals to almond growers rather than honey provide the major income for beekeepers, but honey is an important product in the foothills.

Delta farm tour gives UC students a broader view of food system

“Eighty percent of waterfowl depend on agriculture for food,” said Dawit Zeleke, second from right.

UC Global Food Initiative student fellows from University of California campuses throughout the state gathered for a springtime field trip in the Central Valley to learn more about the relationships between food, farming and the environment.

The day-long tour, hosted by UC Agriculture and Natural Resources, began at a farm that is maintained to support wildlife in the breezy Sacramento-San Joaquin River delta region. The GFI fellows also viewed a habitat restoration project at LangeTwins Winery then watched freshly harvested cherries being processed at Morada Produce's packing plant. They wrapped up the day with a tour of a demonstration garden and a discussion of nutrition education at the UC Cooperative Extension office in Stockton. 

UC President Janet Napolitano, who, along with UC's 10 chancellors, launched the Global Food Initiative in 2014, met with the 17 fellows for lunch at LangeTwins Winery.

“We started the Global Food Initiative several years ago with the goal of creating a pathway to a sustainable, nutritious food future for the planet. A small, modest goal,” Napolitano said, adding that she is excited to learn about the fellows' projects.

The GFI fellows are working on projects that range from raising awareness about food production to analyzing the effects of climate change on pollination, and from efforts to make soils safe for growing food in urban areas to using food waste to fuel batteries.

UC Merced senior Ever Serna's GFI project is to educate his fellow college students about where food comes from, before it gets to the grocery store.

“The tour gave me a deeper understanding and appreciation about how food is developed and grown,” he said. “I think when I eat vegetables and fruits, I'm going to be more conscious of what I eat now.”

Reid Johnsen, a third-year Ph.D. student in agricultural and resource economics at UC Berkeley, Global Food Initiative fellow for UC ANR, and participant in the Graduate Students in Extension program, is working with UC Cooperative Extension in Sonoma County to study ranchers' preferences for different payment structures for conservation easement to compensate them for the ecosystem services provided by their land.

“To be able to see agriculture in action makes such a difference to me, to see the way the crops are produced and the variety that's out here,” said Johnsen. “The diversity of crops was not something I was aware of before coming on this trip.”

President Napolitano visited with the GFI fellows over lunch.

“I thought it was interesting to see a lot of different agricultural production systems,” said UC Santa Barbara senior and campus GFI ambassador Bryn Daniel, who works with student activists on student food access and housing security issues.

In addition to learning more about food production, the outing gave the fellows an opportunity to network with peers from other campuses.

“That's what I liked about today's meeting, just meeting everybody and getting these fantastic connections,” said Ryan Dowdy, a third-year Ph.D. student at UC Davis who is converting food waste into energy-producing microbial fuel cells.

“I think this program, and especially the fellowship, is really important for young scientists who dive into this really huge subject of global food,” said Claudia Avila, a graduate student at UC Riverside who studies trace metals in urban agricultural soils.

Best kept secret

In welcoming the UC GFI fellows, Glenda Humiston, UC vice president for agriculture and natural resources, said, “I have a feeling a lot of you aren't familiar with our division. As I travel around the state to different campuses, I keep being told that we're the best kept secret, which I personally do not think is a good thing." 

She explained that agricultural research has been part of the University of California since the land-grant institution's beginning in 1868 in Oakland. UC ANR has researchers on the Berkeley, Davis and Riverside campuses and UC Cooperative Extension advisors in the county offices, she said, adding, “Here in California, our advisors have very robust research programs.”

Aaron Lange, left, explains that he planted the elderberry bush to create habitat for the threatened valley elderberry longhorn beetle.

Farms are wildlife habitat

Michelle Leinfelder-Miles, UC Cooperative Extension delta crops advisor, introduced Dawit Zeleke, associate director of conservation farms and ranches for The Nature Conservancy, who explained why he farms 9,200 acres of corn, triticale, potatoes, alfalfa and irrigated pasture to enhance foraging habitat for sandhill cranes and other wildlife on Staten Island. The Nature Conservancy partners with UC Cooperative Extension along with the U.S. Fish and Wildlife Service, the U.S. Geological Survey, California Department of Water Resources, Oregon State University, UC Merced and UC Davis to study the relationships between agriculture and natural resources.

The Pacific Flyway for migrating birds passes over the delta. “Eighty percent of waterfowl depend on agriculture for food,” Zeleke said. After wheat harvest, they flood the fields. “You should see it in September, October, November and December. Thousands of birds, ten thousand cranes use this place for habitat.”

Randy Lange, on right, said, "We reuse our water as much as possible." Waste water from the winery is captured and used to irrigate vineyards.

Lodi region is zin-ful

En route to lunch, Paul Verdegaal, UC Cooperative Extension viticulture advisor for San Joaquin County, described the Lodi region's wine industry. There are about 750 growers, many of which are small family operations. While 10 to 15 acres used to be typical vineyard size, most have 100 acres to be sustainable and one family member works at an outside job. 

“Agriculture is a tough job and there is no guaranteed income,” Verdegaal said.

About 40 percent of the zinfandel in California is grown in the Lodi region, but there are several wine grape varieties planted. 

Pointing out the bus window to a vineyard interplanted with a crimson clover cover crop, Verdegaal said, “We do see interest in using as few chemicals as possible and using techniques of the integrated pest management program.”

After eating lunch at LangeTwins Winery in Acampo, the GFI fellows took a tour of the winery with the fourth- and fifth-generation owners, Randy Lange and Aaron Lange. The Langes are founding members of the Lodi Rules Program, which helps growers produce grapes and wines in a manner that is environmentally respectful, socially sensitive and economically sound. They pointed out an array of solar panels covering the grape press room that provide electricity. The Langes are planting native plants around the winery to reduce sedimentation, improve water quality and restore wildlife habitat along the Mokelumne River.

The cluster cutter gently separates the cherry clusters into individual cherries.

Bing is king of cherries

When the GFI fellows visited at the end of April, sweet cherry harvest had just begun in Bakersfield area orchards, and cherries were being packed and shipped in San Joaquin County.

“Hemmed in by rain to the north and heat to the south, cherry season is only eight to 10 weeks long,” said Joe Grant, emeritus UC Cooperative Extension farm advisor for San Joaquin County.

“While the Bing variety is still the mainstay of the California cherry industry because of its excellent eating and shipping quality,” said Grant, “acreage of other high quality and earlier-maturing varieties has increased in recent years to lengthen the harvest season. But Bing is still king.” Asked about the effects of climate change on cherries, Grant explained that warmer temperatures are reducing the number of winter chilling hours, which cherries need.

Morada Produce uses waste water from the cherry processing plant to water these walnut trees, said Scott Brown, fifth from left.

The fellows saw the hand-picked fruit being processed for packing at Morada Produce, a family farm in Linden that also grows walnuts, peppers and onions.

“Keeping produce cold is key to maintaining quality,” said Scott Brown, Morada's production manager, as the fellows watched fresh, cold water rain down onto the freshly picked sweet cherries. The leaves and stems floating to the top were removed as the red clusters glided in the water to the cluster cutter, which gently separated the clusters into individual cherries.  Gently conveyed through the plant in flowing water, the cherries were sorted by size and quality at the highly mechanized facility. Air ejectors spit out rejected fruit, so only 70 percent makes it into a packed box. 

“Fruit picked on Monday is packed Tuesday, then shipped to Korea, Japan, Australia and other export markets to be eaten by Friday,” Brown said.

The fellows were fascinated to see the steps taken to ensure high-quality cherries are cooled, sorted and packaged for shipping to stores and consumers. 

“It was just so much more complicated than I knew,” said Jess Gambel, a third-year Ph.D. student at UC San Diego who is studying the effects of climate change on bee pollination in squash plants.

UC Berkeley graduate student Sarick Matzen reads about the brightly colored plants in the demonstration garden that attract bees, butterflies and other pollinators.

Sustainable gardening

The tour wrapped up at the UC Cooperative Extension office in Stockton, with a discussion about how UC CalFresh and the Expanded Food and Nutrition Education Program help low-income Californians attain adequate nutrition and food security, followed by a tour of the demonstration garden maintained by the UC Master Gardener Program volunteers.

“There are more pollutants in urban runoff than in ag runoff,” said Karrie Reid, UC Cooperative Extension landscape horticulture advisor in San Joaquin County. Reid described how she and the UC Master Gardeners work with home and community gardeners to reduce pesticide and water use, and noted that a Water Use Classification of Landscape Species plant list, based on UC research, is available to help gardeners choose landscape plants.

“As a soil scientist, I really appreciated the recurring emphasis on soils as the foundation for agriculture,” said a fourth-year Ph.D. student at UC Berkeley and GFI fellow with Lawrence Berkeley National Laboratory. “From talking with The Nature Conservancy farm operator about how they were conserving carbon in those soils and doing wetlands management to hearing about special properties of the sandy loam soil in this part of the county, and talking with the Master Gardener folks about soil contamination issues.”                      

This is the third class of GFI student fellows. The undergraduate and graduate student fellows, representing all 10 UC campuses plus UC Agriculture and Natural Resources and Lawrence Berkeley National Laboratory, have helped further UC's Global Food Initiative efforts to sustainably and nutritiously feed the world's growing population by working on food-related projects and raising awareness of this critical issue.

The Biology of Farm Size – Or How I Learned to Doubt my Spreadsheets

I'm a spreadsheet guy – I love plugging numbers and formulas into Excel and getting answers!  I use spreadsheets to analyze the economics of my business, to predict the amount of pasture grass available for my sheep, and to keep track of orders for my lamb.  As a planning tool, spreadsheets can be enormously helpful – but they can also be dangerously seductive.  For example, by simply tweaking a single number (like expected lambing percentage), I can turn a projected unprofitable year into a profitable one!

As I continue to think about the question of scale in sustainable farming and ranching, however, I've begun to see the danger in relying on spreadsheets alone.  Spreadsheets can tempt us to omit biology from the equation.  Let me explain:

There is an upper limit to what an acre of even the most fertile farmland will produce.  Based on the yield estimates supplied by Johnny's Seeds, an acre of sweet corn will produce 14,400 ears of corn.  Even charging $1/ear, an acre of sweet corn, obviously, won't support a full-time income for the farmer (which is why most local farmers grow more profitable crops).  So let's look at a “sexier” (at least according to food writers) crop like kale!  An acre of kale will produce 16,275 pounds of harvested product – that's a lot of kale smoothies!  My colleague Jim Muck reports that he charges $2 for a half-pound bundle of kale.  At that price, an acre field of kale would generate $65,100 in gross revenue – not bad, right?!  But wait – aren't there costs associated with growing that acre of kale?  Certainly the farmer must put in considerable labor – which has a cost to it.  Then there's water, fertilizer, seed, supplies, fuel, marketing costs, storage costs, insurance, land rent (or a mortgage) – that $65,100 in revenue might be offset by as much as $50,000 to 60,000 in direct and overhead costs.  In my world, $5,000 to $15,000 isn't enough income to support my family for a year.  In other words, the biological limits of my acre of farmland suggest that I need to operate at a larger scale if I want to make a living.

Perhaps livestock operations are different – let's take a look!  In our part of the Sierra foothills, an acre of unirrigated rangeland pasture will, on average, grow enough grass to support five mature ewes for one month (these five ewes will need 12 acres of rangeland to get through the whole year).  One acre of irrigated pasture will support my five ewes for six months.  If I do everything right in caring for my ewes, these five sheep will give birth to 8-10 lambs.  If I finish these lambs and sell them as meat at the farmers market, I'll gross $2,400 to $3,000 – all from my acre of land!  Just like my friend the vegetable farmer, however, I'll have expenses – things like processing charges, transportation, insurance, land rent, water, veterinary costs, and supplemental feed costs.  My net income – which pays my “salary” – is $300-500 from these 8-10 lambs.  Once again, biology suggests that I need to operate at a larger scale.

Spreadsheets make it dangerously easy to manipulate these numbers and projections.  If I can boost my projected yield of kale by just five percent, it makes my bottom line look much more attractive!  Unfortunately, these biological limits don't allow us to fudge our numbers that much.  Size, as it turns out, does matter (at least economically). 

Don't get me wrong – I'm not advocating for huge monoculture farms.  I do think, however, that the romantic notion of micro-farming (less than 2 acres) – the darling of our local food movement – is not the answer, either.  If Auburn (for example) needs 25 pounds of kale per person to satisfy local demand for kale, the community would need to grow just over 22 acres of kale.  Would 22 1-acre kale farms (none of which would be paying its owner a living wage) be more sustainable, or would it be better to have one or two kale farms that paid the farmer a reasonable annual salary?  In other words, do we want a local food system that requires farmers to subsidize their farms with outside income and/or unpaid labor, or do we want a system that is economically viable for consumer and farmer alike?  I worry that we may be creating a farming system that requires its farmers to have another source of income (like an off farm job or a retirement fund) in order to keep farming – such a system means we won't likely see young families able to start farms that will be viable over the long term.

I still use spreadsheets in my ongoing attempts to look at the economics of my business, but I've realized that the allure of adjusting the numbers until the farm looks profitable is dangerous (at least for me).  My future spreadsheets will begin with the parameters set by the productivity of my land – there is an upper limit to what my soil can produce.  My projections must be anchored in reality – and informed by my experience and the experiences of my fellow farmers and ranchers.  My spreadsheets must take biology into account!

What Drought!? Perceptions and Reality about Water in the Sierra Foothills

Last Tuesday morning, my job with UC Cooperative Extension took me to the Roseville Farmers' Market at the Fountains Shopping Center.  As I was leaving the market, I drove past the water fountains for which the center is named – and found them running!  While I'm not sure whether these water features use recycled water (I sure hope they do), they symbolize our collective lack of awareness – and lack of concern – regarding California's drought.

When our “water year” ends on June 30, we will have received somewhere around half of our normal precipitation – other parts of California have fared far worse.  Those of us who have rangeland livestock operations have been feeling the effects of this lack of precipitation since last fall.  If you'll remember, we had a good rain on Labor Day last year, followed by dry weather for the rest of September and much of October.  The grass that germinated with the Labor Day rain didn't survive.  We had our next germinating rain in November, followed by a cold spell.  After we measured a half-inch of snow in early December, we were dry for a record-setting 50+ days.  While we had more than 8” of rain over the course of 4 days in early February, the grass on our rangelands really didn't grow until March.  I'm sure the abnormally dry winter also impacted many orchards and vineyards as well – impacts that some growers are just starting to see now.

The lack of snowpack this year was even more severe.  In our region of the Sierra, the May 1 snowpack was just 22 percent of normal.  As of June 9, our snowpack had disappeared – the Department of Water Resources (DWR) reports that our snowpack is 0 percent of normal for that date (as a comparison, during a pack trip south of Sonora Pass in August of 1996, I rode through 3-4 foot snowdrifts).  Our summer irrigation water – whether we're customers of the Nevada Irrigation District (NID) or Placer County Water Agency (PCWA) – depends on our ability to store water in the form of snow.  The reservoirs that NID and PCWA operate don't have enough capacity to store all of our water needs without some of this water coming into the system as late-season snowmelt.  Based on the DWR numbers, our snowmelt has ended for this water year.

While most of us think of drought as a weather phenomenon, droughts can be created through law and regulation as well.  Back in January, Governor Jerry Brown declared a drought emergency.  In his declaration, the Governor indicated that curtailment of water diversions might be necessary to preserve water supplies.  In late May, the State Water Resources Control Board (which regulates surface water rights) sent letters to all of the “junior” water rights holders in the Sacramento River watershed ordering them to stop diverting water immediately.   Locally, this meant that NID has to allow any water flowing into its reservoirs from these junior (or post-1914) water rights to pass through – in other words, if a stream subject to a junior water right is flowing at 10 cubic feet per second into one of NID's reservoirs, the district has to release 10 cfs at the damn.  This water can't be stored for future use!  To complicate matters further, this curtailment order remains in place for 270 days unless it's lifted (and no one is certain of the process for lifting it).  This means that NID might not be able to store any water from these junior water rights until the end of February 2015 – well into next year's rainy season.  This uncertainty makes me nervous – what happens if we have a warm winter and more of our mountain precipitation falls as rain?  With this order in place, we couldn't store it for next summer's irrigation season.

Back to Tuesday - that evening, I attended a drought meeting organized by the Placer County Farm Bureau.  NID and PCWA provided an update on water conservation efforts and prospects for the rest of this irrigation season.  Both agencies reported that they thought they'd be able to provide full water deliveries to most customers for the full irrigation season (through October 15).  Both agencies also expressed hope for a return to normal precipitation next fall and winter, while conceding that another dry year (or continued curtailment of water rights) could pose challenges for the 2015 irrigation season.

I was astonished by the low turnout at the meeting – only 15-20 commercial farmers and ranchers attended. A number of folks, like me, had livestock operations.  Others grew mandarins or other permanent crops, and one or two grew vegetables.

All of us – myself included – take water for granted, I think.  Once NID and PCWA announced this spring that they'd be able to make full water deliveries, many of us put our worries about the drought on a back burner.  Water continued to flow; we moved on to other worries.  For many of my vegetable-grower friends, the mild and dry spring was actually a benefit – they were able to work ground and plant much earlier than normal, which allowed them to bring crops to market sooner than normal.

As for me, I can't shake the idea that we're not out of the woods yet.  I think back to what our rangelands looked like in January and February, and I'm frightened by the prospects of another dry fall and winter.  I found a great quote on the California Water Blog (written by UC Davis professors Jeffrey Mount and Jay Lund) – “Hope is not a strategy.”  While I certainly hope that we have a wet winter ahead of us, I continue to work on my drought strategy.  In other words, I'm hoping for the best but preparing for the worst.

What does this look like for your operation?  I find myself looking ahead to the quality and quantity of forage that I can take our sheep to in September and October – and looking even further ahead to December and January.  If it doesn't rain this fall, I'm stockpiling dry grass pastures to graze during the winter months.  We've also identified small irrigated pastures that will allow us to prepare our ewes for our fall breeding season – rather than finishing lambs on these pastures this summer, we're saving them for the ewes with the hope that we can increasing next year's lambing percentage.  We're also looking at opportunities for improving our irrigation technology – more efficient sprinklers and soil moisture monitoring.  I'm going to start looking into options for planting forages that are more drought tolerant than our typical irrigated pasture grasses.  Finally, I'm starting to think about ways that I can take advantage of good rainfall years – both economically and ecologically.  Perhaps I'll buy feeder lambs in years when we have strong forage growth – perhaps there are other options as well.

Several weeks ago, I was talking to a neighbor at one of the ranches we lease.  I told her about some of the things we'd had to do to cope with the dry winter and spring.  Commiserating, she told me that her kids were terribly disappointed that the sprinkler park in Rocklin had been closed because of the drought.  While I realize that she told the story out of sympathy, I was struck how insulated most non-farmers are from this drought – the Fountains in Roseville are another example.  Tuesday night's meeting reminded me that farmers and ranchers aren't immune from complacency.

Here are some links to resources and information about the drought:

Videos explore the future of farming

Harvest day for Sara Kosoff, Anthony Waldrop and Eric Lynn at UC Davis Student Farm
Pop quiz: About 7 billion people live on earth today, and that number is expected to hit 9 billion by 2050. That’s a lot of mouths to feed. What’s the best way to reform our global food production to meet the rising demand?

  1. Invest in technology, plant breeding, soil science and seed genetics to make our finite farm land more productive.
  2. Increase sustainability, so farm land can remain productive in the future.
  3. Encourage more people to get into farming. 
  4. Help farmers manage climate change, water supply and pest control.
  5. All of the above and a whole lot more.

Yep, the answer is e. All of the above and a whole lot more. Many of the challenges and solutions are explored in a new video series on YouTube called "9 Billion Mouths to Feed: The Future of Farming."

Produced by UC Davis in cooperation with University of California’s "UCTV," the four 10-minute videos provide an excellent overview of modern problems facing our food supply.

"There’s a growing population and we’re going to need to produce more food in a sustainable way to feed them all," says Genevieve Lipari, a UC Davis student featured in the videos. “And it’s not just agriculture, it’s food access, health, nutrition and so much more.”

Indeed, agriculture isn’t just about sowing the land. The videos bring that fact to life, showing the work California farmers and UC Davis students and researchers are doing to ensure an abundant food supply that’s healthy, tasty and safe.

The videos are perfect for students young and old, and anyone interested in finding innovative ways to feed the world without depleting our limited resources.

We might not have all the answers on how to feed a growing population, but the videos shine light on some of the many farmers, scientists and students working together to try to meet that growing need.
