Rick Taggesell always has been interested in gardening, but when he looked up a book online, he was surprised to see an unexpected picture on the cover: a fish.
The Sonoma Valley High School sophomore had stumbled on a guide to aquaponics, the emerging practice of raising fish and food crops in a tightly interconnected loop. Fish provide fertilizer for the plants; the plants filter the water for the fish.
Through the agriculture program at the high school and the FFA club, Taggesell has made a working model of the process and holds out the possibility of pursuing this form of agriculture as a career.
"I don't know how many jobs there are in it at the moment," the 16-year-old said, "but it's going to become more important" as the climate changes and water-starved regions such as North Africa look for sustainable ways to feed their people.
Taggesell is among hundreds of Sonoma County students in ag-related classes and clubs who could benefit from a new commemorative license plate hitting the streets this month, honoring California's agriculture industry. The extra fees associated with the plates will raise money to fund agricultural education statewide.
Agriculture teachers at the county's high schools say their programs are thriving despite the increasing urbanization of the region. At Sonoma Valley alone, the FFA club has swelled by 100 in recent years, to nearly 400, teacher Felicia Rush said.
The nature of the programs, however, has changed dramatically. High schools statewide have partially shifted away from traditional vocational education toward an academically rigorous college prep program, Rush said, focusing more and more on agricultural technology, business, and even emerging new fields like aquaponics.
"Students are starting to see different kinds of agriculture and they're getting interested," Rush said.
There are about 300 high school agriculture programs statewide, enrolling roughly 73,000 students in at least one class per year, said Bob Heuvel, program manager for agriculture and home economics education for the state Department of Education. All of those students are automatically enrolled in FFA, formerly known as "Future Farmers of America."
The curriculum has evolved over the years to include leadership and personal development, he said, and is increasingly being used to give students hands-on exposure to science, math and other core disciplines.
