Farm advisors: They're the local hand on the long arm of the University of California Agriculture and Natural Resources (UC ANR). They apply cutting-edge research to problems facing their farming neighbors, often adapting practices and research results to local conditions. UC ANR Cooperative Extension advisors provide locally adapted science to local farmers.
So it might come as a surprise that some farm advisors got their start in agriculture nowhere near their backyards or their neighbor's fields. In fact, more than a few farm advisors fell in love with helping farmers while they were overseas.
But as a UC Davis grad student, Lundy traveled to Malawi for a few weeks to help extension agents there teach farmers modern tomato-growing practices — as part of a Trellis project with the Horticulture Innovation Lab.
Lundy wrote about his experience in Malawi recently on the Feed the Future website. He describes setting out, eager to put “book learning” to practical use, and eventually realizing how valuable local knowledge can be for agriculture. While in Malawi, Lundy worked with a local agronomist named Chimwemwe:
“Seeing Chimwemwe's extension program in action underscored to me that agriculture is simultaneously (even paradoxically) a global and a local enterprise. Many of the fundamentals of cropping systems do apply broadly across diverse agricultural landscapes, which is what permitted the productive conversations and collaboration between us. Nevertheless, there is no substitute for a nuanced understanding of the particular contours and constraints of any given region or farm.”
Though Lundy had years of formal education in agronomy, he witnessed how Chimwemwe's relationships and local understanding made him a “sharper tool” when it came to helping local farmers.
“Observing Chimwemwe in action inspired me to leverage the regionally specific knowledge I had gained about California agriculture during my graduate education and try to become a similarly sharp tool in my own backyard,” Lundy wrote.
You can read the rest of the article, “How a Global Trip Inspired this Californian to Focus Locally” on the website for Feed the Future, the U.S. government's global hunger and food security initiative. The initiative brings American ingenuity and expertise to bear in the global fight against hunger. Several agricultural research programs at UC Davis and UC Riverside fall under the banner of Feed the Future — including the Horticulture Innovation Lab, led by UCCE specialist Beth Mitcham.

I’ll admit that one of my favorite things to do on a hot day is to walk into an air-conditioned room. That burst of cool air in those first moments can be so refreshing.
It turns out I’m not alone — fruits and vegetables like to be cool on hot days too.
Controlling temperature helps regulate the aging process of a fruit, along with its water loss and microorganism growth. Storing fruits and vegetables at their lowest safe temperatures means they taste better and last longer.
To help us know the best ways to store fresh produce at home, the UC Davis Postharvest Technology Center offers a free PDF poster Storing Fresh Fruits and Vegetables for Better Taste, which includes tips for different fruits and vegetables, from avocado to watermelon.
Knowing the right temperature is only part of the battle for farmers, who are responsible for the first links in the cold chain. Getting produce out of the sun and cool for storage can be a big challenge — and an expensive one.
But a farmer in New York, Ron Khosla, answered this challenge with a tool that can help make cooling produce less expensive for small-scale farmers. He created the CoolBot, a micro-controller that turns a well-insulated room with a regular air conditioner into a commercial cool room for storing fruits and vegetables.
Just as small-scale American farmers struggle with affordable cooling, so do smallholder farmers elsewhere in the world. Researchers with the Horticulture Collaborative Research Support Program (Horticulture CRSP) decided to test the CoolBot device, first at the UC Davis Student Farm and then with farmers in India, Honduras and Uganda.
Indeed, the CoolBot-equipped rooms worked, and the program is building more in Bangladesh right now. But there is a catch: Farmers must have access to reliable grid electricity for a cool room like this to work. To address this problem, the CoolBot in Uganda was powered with solar photovoltaic cells, but that led to another set of challenges — expensive equipment and fear of theft.
So how do you effectively cool vegetables, hot from a field, without grid electricity? A solution that is low-cost, effective and off-grid has not been found yet. In an effort to uncover such a solution, Horticulture CRSP will soon be launching a technology design competition that asks that very question. Can you answer this challenge?
What if you could significantly improve the nutritional quality of your diet, just by switching one of the vegetables you eat every day?
In parts of Africa, some people are doing just that by switching from yellow or white sweet potatoes to orange-fleshed varieties.
That orange color signifies the potato’s beta-carotene content, which our bodies convert to vitamin A. Vitamin A deficiency is the leading cause of preventable blindness in children and is crucial to the survival of children and pregnant women, according to the World Health Organization.
So scientists and organizations who are working to increase vitamin A in African diets have turned to the orange-fleshed sweet potatoes as a potential solution, wherever light-colored sweet potatoes loom large.
With funding from the U.S. Agency for International Development, Horticulture CRSP is working in Ghana to strengthen the entire value chain of orange-fleshed sweet potato — from farmers and food processors, to markets and consumers.
Though Horticulture CRSP is led by UC Cooperative Extension’s Elizabeth Mitcham at UC Davis, this project includes a team of international researchers with experts from Tuskegee University, Penn State and Ghana University. Together, they are working to:
- provide farmers with germplasm and best management practices
- teach women entrepreneurs to process orange-fleshed sweet potatoes into bread flour, purees and dehydrated chips
- formulate a weaning food for babies that incorporates orange-fleshed sweet potatoes with other, traditional foods

Did you know? In 2011 California was the second largest producer of sweet potatoes in the United States, with North Carolina leading the way (source). Find out more in this related ANR News Blog post or from the UC Vegetable Research and Information Center.
You’ve probably heard it millions of times in your lifetime, but it bears repeating: Not everyone has enough, good food to eat.
To that end, the Horticulture Collaborative Research Support Program at UC Davis builds global partnerships for fruit and vegetable research to improve livelihoods in developing countries.
Through Horticulture CRSP’s Trellis Fund, these students have been matched with organizations in Nepal, Uganda, Rwanda, Kenya, Tanzania, Honduras and Nicaragua to provide their agricultural expertise in assisting the organizations' projects with smallholder farmers.
Besides supporting local farmers in developing countries, the projects will also potentially infect students with an interest in international agricultural issues.
“With the Trellis Fund, our goal is to engage young people in an international experience — a chance to partner with a small organization working with real people with real needs and apply what they know about science,” said Beth Mitcham, UC Cooperative Extension specialist in the Plant Sciences Department at UC Davis and director of Horticulture CRSP. “For a small investment, we’re creating lasting relationships and perhaps changing the career path of a young person.”
What will be the new food frontier? An article in the Wall Street Journal with the headline “Next Stop for Food Fanatics: Africa” predicts adventurous American palates may soon be craving sub-Saharan cuisines.
Have you heard of these?
- Nakati (Solanum macrocarpon, S. aethiopicum) Also called African eggplant, some types of nakati are eaten for their leafy greens, while others are eaten for their fruit (which can look like a tomato or eggplant).
- Cowpea leaves (Vigna unguiculata) This plant produces black-eyed peas, but the greens of the plant can also be eaten as a vegetable.
- Bbuga (Amaranthus Gracecizans) You might know this plant by its common American name: pigweed.
- Doodo (Amaranthus Dubius) Like bbuga, this type of amaranth is eaten for its leaves in many parts of Africa. In North and South America, varieties of amaranth are usually used as a grain.
- Jjobyo (Gynandropsis Gynandra, Cleome gynandra) Also called spider plant.
Many of these indigenous vegetables are rich in micronutrients such as iron, vitamin A and vitamin B. When it comes to alleviating malnutrition in developing countries of eastern Africa, indigenous vegetables offer workable solutions because they are not only nutritious, but also familiar to the region’s eaters and farmers.
Recently U.S. researchers have been working with indigenous crops like these in east African countries — with funding and support from the Horticulture Collaborative Research Support Program (Horticulture CRSP), led by Beth Mitcham at UC Davis with funding from USAID. In Kenya, Tanzania and Zambia, Stephen Weller of Purdue University is leading a Horticulture CRSP research project on production practices, seed resources, postharvest handling, marketing and nutrition of varieties of amaranth, spider plant and African nightshade.
Take a look at this short video for a little more background:
Just as bok choy, an Asian vegetable, has become familiar to many American households, perhaps one day you’ll find nakati or another African leafy vegetable on your plate.
In the meantime, researchers with Horticulture CRSP are working to get more African leafy vegetables into the research agendas, fields, markets and plates of our counterparts in eastern Africa.
