CoolBots making news 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

How one farmer’s invention is reducing food waste around the world

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.

Agricultural innovations at Kasetsart University, in SciDev.Net video

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
