How do you see dryness? Solar drying is a simple way for smallholder farmers to preserve their harvest, but knowing when food is dry enough to store is complex. UC Davis researchers invented a low-cost, easy-to-use tool that farmers can use to measure food dryness, called the DryCardTM.
In developing countries, mold growth on dried foods is a pervasive problem, which can mean postharvest losses for farmers and unsafe foods for consumers. When mold grows it reduces the market value of dried foods, meaning less income for farmers. But moldy foods can also contain toxins that suppress the immune system, increase disease rates, and cause lifelong stunting in children.
Trip to market inspires a solution
Improving the postharvest drying process for smallholder farmers is something UC Davis scientists Michael Reid and James Thompson think about often. As UC Cooperative Extension specialists, Reid and Thompson have a history of working together in California and around the world on postharvest technologies, including a design for a more efficient solar dryer.
Last summer Reid led a Horticulture Innovation Lab workshop in Tanzania to provide training in postharvest handling of fruit and vegetable crops. The class visited the local market and tested the moisture content of some of the dried foods for sale. They found huge variation between the moisture contents of dried foods — over half were insufficiently dried and susceptible to mold.
“Reducing food losses and waste: Sustainable solutions for Africa” is the theme of the first All Africa Post Harvest Congress and Exhibition. The conference will be March 28-31 in Nairobi, Kenya.
The event will address aspects of postharvest management related to perishable crops, perishable animal products, non-perishable food commodities, capacity development, and related social issues that affect postharvest management.
Registration to attend the conference is $400, or $350 at early-bird rates before Feb. 28. A student rate is also available ($150 or $100 early). An optional excursion trip scheduled for March 28 is available for an additional $50.
The event is supported by a consortium of universities, research and development organizations — including the Horticulture Innovation Lab as one of its sponsors. In particular, the congress was organized by the Kenya Ministry of Agriculture, Livestock and Fisheries, in conjunction with the World Food Preservation Center, hosted by the University of Nairobi, with strategic partnership from the Rockefeller Foundation.

Photojournalist Martin do Nascimento recently traveled to Guatemala’s Western Highlands to explore the Horticulture Innovation Lab’s new project helping farmers use climate-smart agricultural practices for growing vegetables.
The Horticulture Innovation Lab’s newest annual report is fresh off the presses, documenting the program’s accomplishments from October 2015 – October 2016 (FY 2016) as part of the U.S. government’s Feed the Future initiative.
Together with our research partners at universities, government agencies and NGOs, we took important steps this year in improving livelihoods of farmers and their communities through horticulture.
How new innovations and research from the University of California are helping to end global poverty and hunger was the focus of a standing-room-only event recently at UC Davis. Among the participants recognizing these efforts were representatives from the offices of U.S. Representatives John Garamendi, Doris Matsui, Ami Bera, and Mike Thompson.
