Thriving vegetable plants, new experiments in progress, visitors exploring agricultural tools, and an upcoming gardening contest have been keeping the team behind the Horticulture Innovation Lab Demonstration Center busy recently.
While in Cambodia for the Horticulture Innovation Lab’s 2016 annual meeting, I arrived a few days early to visit a project that I have been advising remotely regarding postharvest practices. The project, led by Manny Reyes of North Carolina A&T State University, is working with women vegetable farmers who have been successfully practicing conservation agriculture in the Siem Reap region.
As a postharvest specialist, I was most interested in how the farmers are using some of the low-cost technologies that the Horticulture Innovation Lab is promoting around the world. Specifically, the project has built a cool room equipped with a CoolBot, as well as a grading table and a washing station in collaboration with Kasetsart University of Thailand and the World Vegetable Center (AVRDC). They are also working on a “tuktukbot,” which is a motorbike and trailer equipped with a cooled compartment to transport the produce for sale, maintaining the quality of the fresh produce during hot days.
During my visit I had the chance to meet the local project technicians Ren Ry and Sel Rechaney as well as local farmers. Together we explored farms, storage locations and different transportation vehicles, so I could monitor the trip of fresh gourds and chili peppers from harvest to grading, packing and storage in order to identify postharvest practices they could improve.
The first stop was at the sponge gourd and chili pepper plot where Continue reading Following vegetables from field to market in Cambodia
While the Horticulture Innovation Lab team was recently in Cambodia for its 2016 annual meeting, reporter Jonathon Cox of the Khmer Times in Phnom Penh reached out to learn more about how farmers in Cambodia are using the CoolBot. He had heard about the device at the recent Cambodia Science & Engineering Festival.
The article Cox wrote, “Helping Farmers Keep Their Cool” was published in the newspaper this week.
For it, he interviewed Elizabeth Mitcham, director of the Horticulture Innovation Lab at UC Davis, about the program’s use of the CoolBot in Cambodia.
“I think that cooling is essential to develop a vibrant produce industry in Cambodia based on local products,” Mitcham said. Current estimates suggest Continue reading CoolBots making news in Cambodia
A version of this article originally appeared in the Feed the Future newsletter.
In many developing countries, more than half of all fruits and vegetables are never eaten, but are instead lost to damage or spoilage after harvest. These post-harvest losses can mean that farmers need to sell their fresh produce immediately at whatever price they can get, before they lose the crops that represent investments of labor, water, and agricultural inputs. Improving how fruits and vegetables are handled after harvest can significantly prolong freshness — and cooling is key.
“The three most important aspects of postharvest handling are: temperature, temperature, temperature,” said Michael Reid, a postharvest specialist who works with the Horticulture Innovation Lab at the University of California, Davis. “In the developing world in particular, affordable cooling technology is mostly absent.”
Cooling can be an expensive challenge — even for American farmers.
As a farmer in upstate New York, Ron Khosla knew this problem too well. His vegetable crop was spoiling too quickly, but he could not afford to buy a walk-in cooler for his small farm. So he invented a solution: a small electrical device he called a CoolBot that tricks an air conditioner into getting colder without freezing over, turning a well-insulated room into a cold room for less than it cost to buy a refrigeration unit.

A video from SciDev.Net explores agriculture technologies at Kasetsart University in Thailand, aimed at the needs of smallholder farmers of horticultural crops.
The audio slideshow, “Simple agricultural innovation to empower farmers,” takes a closer look at several low-cost farming tools, including:
- a cold room with a CoolBot for cooling fruits and vegetables after harvest
- two solar dryers, including the UC Davis chimney dryer for drying produce
- a solar-powered pump with drip irrigation system
Reporter Giovanni Ortolani interviewed Poonpipope Kasemsap, professor at Kasetart University, whose comments provide narration for most of the video.
“A lot of things can be done with a small investment, with innovations, in order to help the farmers so that they can live better lives,” Kasemsap says in the video. Continue reading Agricultural innovations at Kasetsart University, in SciDev.Net video
