As the human population on planet earth, now about 7.6 billion people, continues to grow, more will settle in areas prone to wildfire, reported Mary Beth Griggs in Popular Science magazine.
The reporter spoke with UC Cooperative Extension natural resources advisor Sabrina Drill about wildfire preparation.
First, make sure that an emergency kit is up to date and important papers are in a safe place.
“Know that under conditions of mandatory evacuation, you will encounter traffic, frightening conditions, highly limited visibility due to smoke, etc., so being ready and leaving early is really important,” Drill said.
If there is time, there are important last-minute actions that can be taken to minimize potential fire damage. She suggests moving flammable garden furniture and wood piles away from structures, taking down shade cloths or awnings that could trap embers and making sure doors and windows are closed.
"One thing I would not advise is either leaving sprinklers running or hoping that automatic sprinklers will save a structure, as power may be cut, water lines can melt, and the water and water pressure may be needed by firefighters elsewhere," Drill said.
UC Cooperative Extension provides information to guide actions before, during and after a wildfire on its wildfire resources website.
Farmer Vang Thao has been managing a successful farm south of Fresno for nearly 30 years, producing a spectacular array of vegetables – heirloom tomatoes, purple bell peppers, water spinach, bitter melon, Thai eggplant and dozens of others.
Every weekend the family traverses the Grape Vine to set up a visual feast at farmers markets in Santa Monica, Hollywood, Palos Verdes, Torrance and Hollywood. Acclaimed Los Angeles chefs rave about his produce, according to a Los Angeles Times feature story on the Thao family.
Produce like sweet potato leaves, amaranth and black nightshade are essential for families hailing from Vietnam, Laos, Thailand, the Philippines and India who seek ingredients for their traditional cuisine, but the market is limited. Now, small-scale farmers like the Thaos are on the cusp of something with much wider appeal.
One of their crops is moringa, a tropical tree that produces an abundance of fresh shoots to sell at the farmers market booth for $1 a bundle. Moringa is a delicate green that can be added to salads, soups and nearly any other dish. It has a pleasant nutty, earthy and slightly pungent green flavor. While it tastes good, it's the plant's nutrient profile that is commanding attention.
On the internet, moringas are called miracle trees. All parts of the plant are edible – the tender leaves can be cooked or eaten fresh, moringa flowers are considered a delicacy, the tree's young pods can be used like green beans, roasted seeds are said to have antibiotic and antifungal properties. The roots and bark have medicinal potential, but need more study to determine the right dose. A 100 gram serving of moringa greens has more protein than a cup of milk, more iron than a cup of spinach, and is high in calcium, potassium, vitamin C and vitamin A.
Moringa is the Superfood of 2018, according to the trend watchers at SPINS.com. UC Davis nutrition researcher Carrie Waterman is studying moringa's use, production and processing worldwide. She is pursuing moringa for therapeutic applications in treating cancer, HIV and inflammatory bowel disease.
Ruth Dahlquist-Willard, the UC Cooperative Extension advisor to small-scale farmers in Fresno and Tulare counties, recognized moringa's potential to supplement income for Southeast Asian farming families who are marketing specialty Asian vegetables and herbs to immigrant communities.
“Moringa is a drought tolerant tree known for its excellent nutritional content,” Dahlquist-Willard said. “We believe it could improve the economic viability of small-scale farms in our community. We are helping small-scale farmers with moringa product development and marketing.”
Supporting farmers growing moringa in marketing the product to new buyers is an objective of the UCCE moringa project, a partnership with the UC Sustainable Agriculture Research and Education Program, which was funded by a California Department of Food and Agriculture specialty crop block grant. Lorena Ramos, the project lead, is working on developing marketing materials, outreach opportunities, and value-added options.
While using moringa is second nature for many immigrant groups, expanding the market includes demonstrating how easily the green can be used in the kitchen. Dahlquist-Willard and Ramos called on another sector of UC Cooperative Extension – the UC CalFresh Nutrition Education Program – for assistance. UCCE offers nutrition education in schools and community settings to children and families eligible for the USDA's nutrition assistance programs. Each year, Fresno State dietetic students serve two-week internships at UCCE. In 2018, one of their tasks was developing creative, healthful recipes incorporating moringa. Among the recipes were overnight oatmeal, pesto, smoothies, guacamole and energy bites – all with moringa.
“We are publishing the best recipes to share with the public to help them add this nutritional green into their diets,” Ramos said.
Recipe cards and moringa samples will be available July 26 at the Fresno Food Expo, where UCCE is hosting a booth to raise awareness about moringa by introducing farmers to Fresno area chefs, buyers and consumers and sharing information about the vegetable's health benefits, culinary versatility and its ability support small-scale farmers in Fresno and Tulare counties.
Following is a USDA recipe ideal for incorporating moringa:
Grilled quesadilla with vegetables
Nonstick cooking spray
1 medium zucchini, diced
½ broccoli head, diced
1 green pepper, diced
1 medium onion, minced
1 carrot, peeled and grated
16 (6 inch) flour tortillas
12 ounces cheese, shredded
½ cup moringa leaves
- Wash all vegetables.
- Collect, dice, shred and measure all ingredients before starting to prepare the recipe.
- Spray a large skillet with cooking spray. Add zucchini, broccoli, green pepper, onion and carrot. Cook vegetables on medium heat for 4 to 5 minutes, stirring frequently. Remove vegetables from skillet, and put on a clean plate.
- Spray skillet with cooking spray again and place 1 tortilla in the skillet. Top with ½ cup vegetables and 1/3 cup cheese. Sprinkle on fresh moringa leaves.
- Place a second tortilla on top. Cook on medium low heat for 2 to 3 minutes or until the cheese starts to melt and the bottom tortilla starts to brown.
- Flip over the quesadilla. Cook for another 2 to 3 minutes until tortilla brons.
- Repeat steps 4 through 6 to make additional quesadillas
- Cut each quesadilla in half or quarters, serve hot with your favorite salsa or other toppings.
- Refrigerate leftovers within 2 hours. Eat within 3 to 5 days.
At the end of June, the distinguished careers of five UC Cooperative Extension advisors concluded when they retired. The new retirees are
- Mark Gaskell, UCCE small farms advisor for San Luis Obispo and Santa Barbara counties
- Gene Miyao, UCCE vegetable crops advisor for Yolo, Solano and Sacramento counties
- Kim Rodrigues, director of the Hopland Research & Extension Center and UCCE forest advisor
- Blake Sanden, UCCE irrigation, soils and agronomy advisor in Kern County
- Steve Tjosvold, UCCE horticulture advisor for Santa Cruz and Monterey counties
Below are brief vignettes about each of the retirees.
UCCE small farms advisor Mark Gaskell retires
Gaskell, who began his career with the University of California's Division of Agriculture and Natural Resources as an advisor for small farms and specialty crops in San Luis Obispo and Santa Barbara counties in 1995, retired July 1.
“If it wasn't for Mark Gaskell, I wouldn't have lasted three years,” said Tony Chavez, who grows 40 acres of blueberries, blackberries and some raspberries in Nipomo.
Blueberries weren't grown in California until Gaskell planted test plots of southern highbush blueberries in 1996 to give small-scale growers a new crop option. What was once a niche crop is now planted on over 7,000 acres in the state and California currently leads U.S. production of fresh blueberries.
Recently Gaskell's knowledge of coffee production has been in demand.
“Personally, I would not be where I am today professionally without Mark's guidance, support and friendship,” said Jay Ruskey, CEO and co-founder of Good Land Organics. “He brought me my first coffee plants in 2002.”
With Gaskell's research-based advice, the Goleta grower has produced premium coffee. His Caturra coffee made Coffee Review's Top 30 coffees in 2014 and in 2017 Daily Coffee News reported that Blue Bottle was selling the California-grown coffee for $18 per ounce.
“Industry-wide, there are many farmers who have benefited directly from working with Mark, but there are far more farmers who are currently benefiting today from the specific crops and farming systems he has introduced through his service as a University of California farm advisor,” Ruskey said.

Gene Miyao, UC Cooperative Extension vegetable crops advisor, retiring after 38 years
Miyao had been exposed to UCCE farm advisors from a young age.
“My parents were small-scale farmers in Yolo County. We knew of the value of UCCE and the UC system,” Miyao said.
During his 38-year-career, Miyao has witnessed dramatic changes in production systems of processing tomatoes, a crop on which he focused much of his efforts. Growers went from using open-pollinated seed to hybrids and they changed from direct seeding to transplants. Tomato production has seen a major reduction in Phytophthora root rot, and a rapid spread of Fusarium wilt race 2.
Over the years, Miyao has conducted significant research, including work to better understand the benefits of cover crops, supplemental applications of potassium and phosphorous, and applying composted chicken manure in tomato production. He cooperated with a team of advisors to demonstrate the value of sulfur dust for powdery mildew control and the risk of spreading the disease fusarium wilt from infested stem pieces. Miyao was an author of the recent cost production study titled Cost of producing processing tomatoes in the Sacramento Valley and Northern Delta with sub-surface and surface drip irrigation.
In all Miyao wrote 69 peer reviewed articles. However, he said, the local newsletters, field meetings and field calls were always his priority in order to stay well connected to his local clientele.
In retirement, Miyao said he will complete some of his 2018 field projects. He's also planning to travel with his wife Donna to national parks and other destinations. And he is looking forward to fishing in the local waters. (Author: Jeannette Warnert)
Kim Rodrigues, Hopland Research and Extension Center Director, retires after 27-year career with UC ANR
When she became regional director for the 23 counties in the North Coast and Mountain Region in 1999 and relocated her family to Davis from Eureka, she recounted that “it was July, and they went from cool, coastal fog to the Valley heat and wondered about my sanity!”
She later became the executive director of Academic Personnel for ANR when the regions were restructured and ANR was centralized.
She returned to county-based academic work at HREC in the summer of 2014. Initially there as an interim assignment, Rodrigues fell in love with the place and the people and accepted the formal assignment at HREC in 2015. She notes that working at HREC has been “an excellent culmination to my career. Working with colleagues on relevant research, such as living with wildlife, integrates the many professional roles I have had throughout my career.”
Noted as a competent and trusted forester, she has served on the State Board of Forestry and Fire Protection (BOF) briefly and on the BOF Professional Forester's Examining Committee for several years.
Rodrigues is also known for her collaborative leadership and facilitation skills and led the public participation team, together with Drs. Maggi Kelly and Lynn Huntsinger, for the long-term research titled the Sierra Nevada Adaptive Management Project. She is recognized as an excellent facilitator for large-scale and smaller scale public meetings designed to share science with diverse public interest groups, agencies and decision-makers, in order to seek new solutions for resolving ongoing conflicts over public trust resources, such as water, wildlife and more.
Her passion is working with diverse groups to address complex environmental conflicts to seek shared understanding and new agreements. “It is amazing how diverse input can help frame innovative solutions that individuals or small groups may not readily identify,” she said.
She plans to remain engaged in research and extension related to living with wildlife, cumulative watershed effects and managing conflicts of all types. She is also looking forward to spending more time with her husband, four children and grandchild.
Although sad to leave many aspects of her work at UC ANR, she said, “I remain deeply grateful to UC ANR for such a wonderful career, and I remain committed to support UC ANR to succeed in any way I can going forward. I have been fortunate to work with amazing colleagues and truly respect the work we do for the land grant mission.” (Author: Liz Sizensky)
Blake Sanden, UCCE irrigation, soils and agronomy advisor in Kern County
He helped growers with on-farm soil and water problems, organized and spoke at workshops across California and conducted applied field research projects focusing on irrigation, salinity/fertility management for all crops, and agronomic field crop production of alfalfa, dry beans and oil crops.
Blake has a bachelor's degree in International agricultural development and agronomy and master's degree in irrigation and drainage from UC Davis and 35 years of experience in California production ag, international ag development and extension.
Significant projects of his include: development of salt tolerance thresholds for high production California pistachios in the San Joaquin Valley, soil moisture monitoring techniques and irrigation efficiency assessment on 12,000 acres in Kern County and deficit irrigation in early citrus navel oranges.
Over the last eight years, Sanden has fulfilled a vision that started nearly 30 years ago. Through collaboration with nearly 50 University of California researchers, farm advisors, extension specialists, the Wonderful Farming Company and almond industry representatives, he played a crucial role in documenting the increased level of water and fertilizer use necessary for optimal almond yield – increasing the statewide average yield by more than 50 percent.
But some of his greatest joys and heart-felt satisfaction lay in development work in Africa – 3 years of missionary service in the 1980s developing vegetable gardens in Zambia and month-long training/consulting trips working with farmers and extension agents in Uganda, Ethiopia and central Asia.
When asked what he'll miss the most about his career, he said the interaction with the growers, most notably “seeing the ‘ah-ha' light up in a grower's eyes when he finally grasps the solution.”
He remembered a particular time in May of 2004 when a sugarbeet grower called him seeking his advice on whether or not to irrigate his 380 acres of beets one last time before harvesting. That was the way he had always done it. So Sanden went out and spent a couple of hours using his hand probe to check the moisture of the fields down to a three-foot depth.
“I ask, ‘Ken, when did you last probe this field?'” Sanden recalled.
‘“Oh, I really didn't check it this year?' he says.”
“Do you really need to irrigate or is this enough water to get through harvest?” noting that he already had enough moisture.
“I guess it's enough, but that's why I asked you out here. It wouldn't hurt to put on the irrigation would it? I'd feel better. Of course we did get the digger stuck a couple times last year because the field was too wet.”
“Too much water does hurt beets because you will reduce sugar percentage and can get rot and lose tonnage,” Sanden replied.
“OK, it makes me a bit nervous but you say I have at least four inches of water stored in the soil that the beets can get at.”
That year Ken was the top sugar producer in Kern County and got the Silver Beet Knife for highest percentage of sugar, Blake recalled.
“With that two hours worth of field scouting he probably made an extra $300,000 in the saved irrigation and increased sugar,” Blake said. (Author: Tyler Ash)
Steve Tjosvold, UC Cooperative Extension environmental horticulture advisor, 38 years
joined UC Cooperative Extension as a farm advisor intern from 1980 to 1983, working in Alameda, Orange and San Bernardino counties. The internship allowed recent college graduates the opportunity to get experience working with a UCCE advisor in their field of interest.
“I interned for two advisors and then separately filled in for the programs of two advisors that went on sabbatical leave,” Tjosvold said. “I use that experience, knowledge, contacts and friendships to this day.”
Tjosvold was named the environmental horticulture advisor in Santa Cruz and Monterey counties in 1983.
Tjosvold's early career focused on the management of nursery and landscape plant diseases and insect problems, as well as methods to improve water use and postharvest handling in nursery crops. In addition, Tjosvold helped establish the use of scouting in ornamental production by working with other farm advisors to document effectiveness statewide. Later, his research and outreach on sudden oak death and light brown apple moth helped growers understand the pests and take action to reduce their impact on production systems and the environment.
Tjosvold wrote or contributed to 94 peer-reviewed publications and 234 industry publications. He served as editor/co-editor of UCNFA (UC Nursery and Floriculture Alliance) News.
During his career, Tjosvold received three distinguished service awards for outstanding teamwork (1997, 2004, and 2006) and one for outstanding extension (2004). He received the 2008 Western Extension Directors' Award of Excellence for a farm water quality planning project. In 2012 he received the outstanding research award from the California Association of Nurseries and Garden Centers, and in 2015 he was honored with the Award of Excellence from the Western Extension Directors Association for a team effort that addresses Sudden Oak Death.
In retirement, Tjosvold plans to start a UCNFA blog to help replace the loss of the UCNFA newsletter due to retirements. He will also be available locally for focused educational projects and consultation. Tjosvold, an avid fly fisherman, said he will spend the first month of his retirement camping and fly fishing in Montana. (Author: Jeannette Warnert)
In the late 1800s, when automobiles started replacing horses in the United States, farmers were likely pondering how the new technology could be adapted for agricultural production. Before long, tractors revolutionized the industry.
A similar scenario unfolded in June at a UC Cooperative Extension field day in Merced County. Farmers, scientists and entrepreneurs gathered at Bowles Farm in Los Banos to learn how drones may be deployed on farms of the future to improve irrigation, fertilization and pest management practices and monitor the crop to maximize yield and profit.
Instead of driving a pickup truck around the perimeter of the field, pushing through hip-high row crops, or meticulously sampling dozens of tree leaves, a quick fly-over with the right equipment could provide farmers all the data they need to make production decisions.
This won't happen tomorrow. Regulations still hamper drone use and the cost of some equipment is prohibitive. But UCCE advisor David Doll is working with scientists at UC Merced and Fresno State to find low-cost alternatives for data collection and analysis that will make the information collected by drones of value to farmers.
“We were able to get good correlation with plant water stress using a thermal camera, however the platform is too expensive,” Doll said.
Doll's research, funded by a grant from UC Agriculture and Natural Resources, uses data from hundreds of drone flights over an almond orchard. The project has shown that monitoring perennial cropping systems from the sky presents challenges.
“Perennial crops will have water stress before the crops show stress,” Doll said. “We need to find an algorithm to identify water stress before it's too late for the orchard.”
Bowles Farming Company, which hosted the field day, flies drones over its farms three days a week, said Justin Metz of the company's technology integration team. The high-definition imagery is shared with the on-staff agronomist, who can diagnose emerging issues.
“Our use of drones is in its infancy, but we're ahead of others,” Metz said. “Knowing the capabilities is really exciting. Drones are here, and they're going to stay.”
UCCE agronomy and weed science advisor Lynn Sosnoskie attended the drone field day to gather ideas and make contacts. She believes drones have the potential to monitor crops for herbicide injury.
“I want to ground truth drone images to see if they can predict yield loss,” Sosnoskie said.
Retired pest control adviser Richard Stewart, one of about 100 attendees, is considering how drones could be used to monitor for rodent damage in irrigation ditch banks.
“I've never see anyone do that,” he said. “I'm just looking into it. It's a new idea.”
UC Agriculture and Natural Resources vice president Glenda Humiston welcomed a delegation of Chinese agricultural scientists to UC ANR's Intermountain Research and Extension Center in Tulelake in June, reported Danielle Jester in the Siskiyou Daily News.
"They're trying to improve their agriculture," Humiston said. "We need all farmers and ag working together, and we need a good working relationship with China – there's a big market there.”
During her opening remarks, Humiston said Chinese farmers faced many of the same issues as those in the U.S.
"They are responding to global climate change, drought and pests while trying to improve food security and water use efficiency," Humiston said. "They see UC Cooperative Extension as an effective research model; we hope that scientific collaborations will accelerate solutions and help maintain relations for California agriculture with China."
The group toured the Intermountain Research and Extension Center, the northernmost of UC ANR's nine research and extension centers.The 140-acre facility is four miles south of the Oregon border. Research at the center is focused on irrigated field and vegetable crops, weed, insect and disease management, water conservation and plant fertility.
During the tour of the station, one of the Chinese scientists asked what factors the researchers look at to determine the health of the soil. In response, center director Rob Wilson listed the soil's nutrients, its bulk density, pH, organic matter content, carbon to nitrogen ratios, existence of microbes, and existence of disease in the soil, Jester reported.
