American Farmland Trust (AFT), the organization behind the national movement No Farms No Food®, has released four case studies that show that healthier soil on farmland brings economic benefits to farmers and environmental benefits to society. These case studies were developed in partnership with USDA’s Natural Resources Conservation Service (NRCS).
The case studies were developed as part of a 2018 NRCS Conservation Innovation Grant (CIG) project, “Accelerating Soil Health Adoption by Quantifying Economic and Environmental Outcomes and Overcoming Barriers on Rented Lands,” and feature farms in California, Illinois, Ohio and New York.
“Increasingly, we understand that better soil health – and specific practices aimed at building soil organic matter, fostering microbial life in the soil, reducing nutrient loss, and protecting soil from erosion – lead to higher net income for farming operations. These case studies contribute to the growing body of quantitative evidence that improving soil health increases farmer profitability,” said Dr. Perez.
The two-page case studies focus on corn-soybean production in Illinois and Ohio, almond production in California and a diversified rotation (sweet corn, alfalfa, corn for silage or grain) in New York. The four farmers featured implemented soil health practices like no-till or strip-till, nutrient management, cover crops, compost, and mulching.
“When it comes to conservation, producers have to make decisions based on what makes the most sense for their operations,” said NRCS Chief Matthew Lohr. “These case studies provide information on the economic benefits of using soil health management systems, demonstrating the value of adopting these systems.”
With soil health management, producers can increase their yield, decrease their risk and input costs, and improve their profits, all while conserving our nation’s resources for the public at large, on their farms, in their watersheds, and beyond. Soil health management systems are good for farmers and for the public.
“Increased implementation of soil health is critical to AFT’s holistic approach to saving the land that sustains us. Ensuring a sustainable future for this planet and our society requires we value the land, the practices on the land and the people who steward that land. AFT’s case studies showcase farmers who took the risk and are now enjoying the benefits of implementing practices that will support food production for a growing population while improving our environment and sequestering carbon. Farmers across the country can now embrace these practices and, with the help of staffers from AFT and our partner NRCS, put them into practice with greater confidence and profitability,” says John Piotti, AFT president and CEO.
Highlights from the case studies include:
All four farmers have been implementing different soil health practices over different time frames and a variety of cropping systems. With these case studies and the ones that will be released in the fall, AFT is building a diverse library of on-farm examples of soil health investments that have led to economic gain.
We hope that farmers who have been considering adding soil health practices to their operation will be able to use these case studies to approach their existing landowners, from whom they rent their land, to discuss sharing the risks and rewards of the soil health investments. We think farmers may be able to use the case studies with a new landlord to add new fields. Should that materialize, we hope farmers will also share the case studies with their bankers to secure additional financing for the farm expansion.
Farmers across the country can reach out to their local NRCS and Soil and Water Conservation District staff to help them implement soil health practices on their farm. In the watersheds featured in the four case studies, farmers can reach out to both the local NRCS and SWCD staff as well as the four AFT authors of the case studies.
We hope our conservation partners at NRCS, SWCD and Extension, plus our partners in the private sector, crop consultants, cover crop seed dealers, and strip-till equipment providers, use these case studies with their customers to help answer questions about the costs and benefits of adopting soil health practices.
AFT’s first four case studies can be found on AFT’s “Accelerating Soil Health” webpage.
During National Farmers Market Week August 4-10, we encourage you to visit one of the 675 CDFA Certified Farmers Markets in California.
CDFA’s role at Certified Farmers Markets is to facilitate the sale of California-grown agricultural products while maintaining sufficient regulatory control to ensure they’re of acceptable quality, and that selling activities are conducted honestly and fairly.
What differentiates a Certified Farmers Market from other farmers markets? It is in a location approved by the respective county agricultural commissioner and its California-grown agricultural products are sold directly to the public by producers and certified producers.
Background
Regulations once required California farmers to pack, size and label their fresh fruits, nuts and vegetables in standard containers to sell in markets anywhere other than the farm site. Then, in 1977, CDFA Direct Marketing regulations exempted farmers from these standardization requirements when certified producers directly market their California-grown agricultural products to the public at Certified Farmers Markets. Benefits include providing consumers the opportunity to meet the farmer and learn how their food supply is produced, as well as the ability for small farmers to market their products without the added expenses of commercial preparation.
Today
Certified Farmers Markets are regulated by CDFA’s Direct Marketing Program of the Inspection and Compliance Branch in the Inspection Services Division, in collaboration with California’s 58 county agricultural commissions. There are currently 675 Certified Farmers Markets throughout California, and approximately 60% of them are seasonal. That equates to more than 28,000 annual marketing events. Certified Farmers Market inspectors conducted approximately 2,800 inspections and investigations this past year.
Click here to learn more about starting a Certified Farmers Market in your area, becoming a certified producer, or learning which certified producers already are in your county. There also is information about the Certified Farmers Market Advisory Committee, including dates of upcoming meetings as they’re determined, previous meeting minutes and how to apply to be a member of the committee, which is composed of six certified producers, six Certified Farmers Market managers, one public member, one agricultural commissioner and alternates.
Additional CDFA Connections to Farmers Markets
The California Nutrition Incentive Program (CNIP) in the CDFA Office of Farm to Fork (CDFA-F2F) encourages the purchase and consumption of California-grown fresh fruits, vegetables and nuts to CalFresh shoppers through a dollar-to-dollar match at Certified Farmers Markets. For every CalFresh benefit dollar spent, CalFresh shoppers receive an additional CNIP dollar that can be spent on fruits and vegetables at the market, within set parameters.
The CDFA Senior Farmers Market Nutrition Program provides low-income seniors a $20 check booklet to purchase produce, herbs and honey at Certified Farmers Markets. CDFA encourages more certified markets and producers to participate in this program by applying for free, attending an interactive training and accepting the checks at their market/farm stall.

The long road to a more perfect avocado certainly didn’t begin in Parlier, Calif. But the tiny agricultural town 30 minutes southeast of Fresno is where a U.S. Department of Agriculture flavor scientist has been pushing samples through sliding doors into evaluation booths, for a panel of tasters to individually consider.
The goal of the study is to figure out how people describe the flavor of a good avocado and what components in the fruit contribute to that perceived flavor, said Mary Lu Arpaia, a leading avocado researcher and director of UC Riverside’s avocado breeding program.
Every Tuesday and Thursday morning, the nine trained participants spend an hour evaluating avocado samples in a University of California sensory science building specifically designed for testing like this, just down the street from an agricultural research service division of the USDA.
The tasters are paid $10 an hour, plus all that free avocado, and their ranks include a few retired schoolteachers and an IT professional. They’re given no more than three avocado samples during each session to avoid burnout, and answer around 14 questions about each sample.
Their analysis is concentrated on two varieties of avocado, Hass and GEM.
The black-skinned Hass variety (rhymes with “class”) is the current gold standard on the market, and accounts for 95% of avocados consumed in the United States. The GEM is a newer species produced out of Arpaia’s lab at UC Riverside, aimed to be better adapted to grow in the San Joaquin Valley, which — if successful — could potentially mean California avocados produced more months of the year. (California avocados are typically in season from spring to late summer or early fall, with production largely limited to coastal Southern California. They account for roughly 90% of all U.S.-produced avocados, but just a fraction of the overall avocados consumed across the country.)
Year-round avocado dishes may dominate your Instagram feed, yet its current nationwide post-seasonal ubiquity is heavily dependent on a delicate balance of geopolitics. But first, let’s backtrack.
Avocados have been cultivated in what is now Mexico and Central America since 500 B.C. The California avocado industry began in earnest around 1915, about a decade before a California postman accidentally originated the Hass avocado in his La Habra Heights backyard.
When the North American Free Trade Agreement was ratified in 1994, the vast majority of avocados consumed in the U.S. were still California grown, and therefore limited to a short seasonal window. NAFTA opened the door for mass avocado importation from Mexico, but it wasn’t until 1997 that an eight-decade ban on importing the fruit from Mexico into the U.S. was lifted.
U.S. avocado consumption has generally trended upward since 1970, but the post-NAFTA influx of access to a year-round supply — coupled with broader culinary and health trends, along with a fast-growing Latino population across the country, and their cultural influence — fueled explosive growth among American consumers. (A 1990s-era concerted effort by avocado marketers to integrate guacamole into the Super Bowl experience is also said to have played a crucial role in boosting sales.)
California still overwhelmingly dominates U.S. avocado production, but imports now account for roughly 85% of all avocados consumed in the U.S., with the vast majority of those coming from Mexico.
California has had a smaller-than-average crop this year, making the country more reliant on Mexican avocados, and prices spiked dramatically in April after President Trump threatened to close the border. Due to a confluence of factors, prices remain so high that some L.A. taqueros have resorted to providing a faux-guacamole that substitutes Mexican squash for the avocados, as Javier Cabral recently reported for L.A. Taco.
The quest to cultivate an avocado that can consistently bear fruit year-round in California has long been a kind of the Holy Grail for horticultural researchers like Arpaia, but it takes on new urgency with the fate of NAFTA potentially hanging in the balance.
Meanwhile, the panel of Central Valley tasters who meet twice a week in Parlier for the USDA’s research have become true avocado evangelists. The group has become friends through the yearlong process, and recently gathered for an avocado-themed potluck, complete with homemade avocado ice cream, avocado cream pie and avocado deviled eggs.

Agricultural insect pests seek out familiar scents to find their plant hosts. However, they can also be repelled by odors from other plant species.
A new study from the University of Vermont published in Scientific Reports offers a novel framework for exploiting plant odors to repel insect pests. The study is the first to show how the similarity of plant odors and phylogenetic relatedness can predict insect repellency.
The team applied this conceptual framework to swede midge, a tiny fly that is becoming a major problem for Northeastern growers of broccoli, kale and other cabbage-family crops. They found that particular essential oils – garlic, spearmint, thyme, eucalyptus lemon and cinnamon bark – were most effective at repelling the midge. The findings come as good news to organic farmers who are without an effective solution for managing the pest.
While essential oils have long been used in pest management, determining which oils are effective has followed a “trial by error” approach, said senior author Yolanda Chen, associate professor in UVM’s Department of Plant and Soil Science.
“People often think more aromatic plant oils, like mint, basil and lavender will repel insects, but usually there is no rhyme or reason for choosing,” said Chen, who is also a fellow of UVM’s Gund Institute for the Environment. “It turns out that as we go along the family tree, plants that are more distantly related from the host plant are generally more repellent.”
Headless crops
Swede midge is a recent invader on vegetable farms in the Northeastern United States. Midge larvae must feed on the brassica plant family in order to survive, which includes many popular vegetables like broccoli, kale, cauliflower, cabbage, brussels sprouts, kohlrabi and collards. Making a mistake and laying eggs on the wrong plant would result in the death of the midge’s offspring.
“Smell plays a major role in host location,” said Chase Stratton, the study’s lead author, who recently completed his PhD at UVM. “Just one landing of one fly is enough to cause marketable damage,” he said.
The larvae “hijack the plant’s control system” resulting in distorted growth, such as headless broccoli and cauliflower, puckered leaves, and brown scarring. Unfortunately for farmers, the damage is not observable until it’s too late and the midge have already dropped off the plant. In areas where the midge has become well established, including parts of Canada, New York, and Northern Vermont, the midge can cause 100 percent crop losses.
To manage the midge, conventional growers have turned to neonicotinoid insecticides, which have been implicated in honeybee decline. With no methods for killing the pest, some organic farmers have simply stopped growing vulnerable brassica crops. This led Chen and Stratton to explore new control options for organic farmers.
A sustainable solution
“It’s hard to get away from using insecticides because they’re good at killing insects,” said Stratton, who is now a postdoctoral researcher at the The Land Institute in Salina, Kansas. “But plants have been naturally defending against insect herbivores for millions of years. Why are we so arrogant to think we can do it better than plants?”
Fascinated by the complexity of plant odors and species interactions, Stratton identified essential oils from 18 different plants that vary in their degree of relatedness to brassica host crops. He and Chen hypothesized that oils from plants that are more distantly related to brassicas would have more diverse odors and be more repellent. Comparing the chemical structures of the odors might hold clues for predicting repellency, they thought.
To test the theory, the researchers observed how female midges behaved when presented with broccoli plants that had been sprayed with each of the essential oils. They found the midges were less likely to lay their eggs on broccoli plants that had been treated with essential oils, compared to the untreated plants, and avoided flying towards certain oils more than others. In general, oils from plants that were more distantly related from brassicas on the plant family tree were more likely to repel the midge. They also found that odors that were more chemically different were also more likely to be repellent. However, the oil that was most repellent – spearmint – actually had odors more similar to the brassica crop.
“Biologically, it makes sense that midges would be able to detect and avoid these plants because the similar odors would make it easier for them to misinterpret these plants as hosts, which would be deadly for their offspring,” said Stratton. “For swede midge, garlic appears to be one of the most promising repellents, particularly because certified organic products using garlic are already available for growers.”
The study suggests a new sustainable solution for this new invasive pest and provides a novel framework for testing pest management strategies in other species.
The California Department of Public Health (CDPH) and the California Department of Food and Agriculture (CDFA) are urging visitors attending fairs to practice good hygiene when visiting farm animal exhibits. Direct and indirect contact with the animals could put individuals at risk of developing Shiga-toxin producing Escherichia coli O157 (STEC O157) and other infections.
“Visiting animals can be one of the highlights of the fair,” said Dr. Charity Dean, CDPH Acting State Public Health Officer. “It is important to remember to practice good hygiene when working with or visiting animals.”
Every year, infections and illnesses in children and adults after exposure to animals at county fairs, petting zoos, and farms have been reported to public health. These have included bacterial infections such as STEC O157 and Salmonella, viruses such as swine influenza virus, and parasites such as Cryptosporidium.
There are steps you can take to protect you and your family at the fair, petting zoo, or other settings where farm animals are present:
* Wash your hands with soap and running water after touching animals or being in areas where animals are housed or exhibited, even if you did not touch the animal.
· Do not eat, drink, or put anything in your mouth while in an area where animals are housed or exhibited.
· Avoid touching your eyes, nose, or mouth until you have exited the animal area and washed your hands with soap and running water.
· Do not take toys, pacifiers, cups, baby bottles, strollers, or similar items into animal areas.
· Always supervise children around animals and supervise handwashing for young children.
· Don’t let children sit or play on the ground in animal areas.
· Avoid contact with animals that look or act ill.
People in high-risk groups should take extra care around animals. These include senior citizens, children under five, pregnant women, and people with a weakened immune system or chronic health conditions.
“We want all California families to enjoy their local community fair, but it is important for them to know good common sense precautions and be sure to wash their hands after contact with animals,” said CDFA Secretary Karen Ross.
If you develop any illness after visiting animal exhibits, including fever, vomiting/diarrhea, or flu-like symptoms, see your health care provider and inform them of your animal contacts.

An estimated 820 million people did not have enough to eat in 2018, up from 811 million in the previous year, which is the third year of increase in a row. This underscores the immense challenge of achieving the Sustainable Development Goal of Zero Hunger by 2030, says a new edition of the annual The State of Food Security and Nutrition in the World report.
The pace of progress in halving the number of children who are stunted and in reducing the number of babies born with low birth weight is too slow, which also puts the SDG 2 nutrition targets further out of reach, according to the report.
At the same time, adding to these challenges, overweight and obesity continue to increase in all regions, particularly among school-age children and adults.
The chances of being food insecure are higher for women than men in every continent, with the largest gap in Latin America.
“Our actions to tackle these troubling trends will have to be bolder, not only in scale but also in terms of multisectoral collaboration,” the heads of the United Nations’ Food and Agriculture Organization (FAO), the International Fund for Agricultural Development (IFAD), the UN Children’s Fund (UNICEF), the World Food Programme (WFP) and the World Health Organization (WHO) urged in their joint foreword to the report.
Hunger is increasing in many countries where economic growth is lagging, particularly in middle-income countries and those that rely heavily on international primary commodity trade. The annual UN report also found that income inequality is rising in many of the countries where hunger is on the rise, making it even more difficult for the poor, vulnerable or marginalized to cope with economic slowdowns and downturns.
“We must foster pro-poor and inclusive structural transformation focusing on people and placing communities at the centre to reduce economic vulnerabilities and set ourselves on track to ending hunger, food insecurity and all forms of malnutrition,” the UN leaders said.
Slow progress in Africa and Asia
The situation is most alarming in Africa, as the region has the highest rates of hunger in the world and which are continuing to slowly but steadily rise in almost all subregions. In Eastern Africa in particular, close to a third of the population (30.8 percent) is undernourished. In addition to climate and conflict, economic slowdowns and downturns are driving the rise. Since 2011, almost half the countries where rising hunger occurred due to economic slowdowns or stagnation were in Africa.
The largest number of undernourished people (more than 500 million) live in Asia, mostly in southern Asian countries. Together, Africa and Asia bear the greatest share of all forms of malnutrition, accounting for more than nine out of ten of all stunted children and over nine out of ten of all wasted children worldwide. In southern Asia and sub-Saharan Africa, one child in three is stunted.
In addition to the challenges of stunting and wasting, Asia and Africa are also home to nearly three-quarters of all overweight children worldwide, largely driven by consumption of unhealthy diets.
Going beyond hunger
This year’s report introduces a new indicator for measuring food insecurity at different levels of severity and monitoring progress towards SDG 2: the prevalence of moderate or severe food insecurity. This indicator is based on data obtained directly from people in surveys about their access to food in the last 12 months, using the Food Insecurity Experience Scale (FIES). People experiencing moderate food insecurity face uncertainties about their ability to obtain food and have had to reduce the quality and/or quantity of food they eat to get by.
The report estimates that over 2 billion people, mostly in low- and middle-income countries, do not have regular access to safe, nutritious and sufficient food. But irregular access is also a challenge for high-income countries, including 8 percent of the population in Northern America and Europe.
This calls for a profound transformation of food systems to provide sustainably-produced healthy diets for a growing world population.
Key facts and figures
-Number of hungry people in the world in 2018: 821.6 million (or 1 in 9 people)
