A cereal and beers are now being made with a new variety of perennial grain known as Kernza. Proponents say this marks a significant advance for a new agriculture that borrows from the wild prairie and could help ensure sustainable food production in a warming world.
Some 40 years ago, Wes Jackson, a plant geneticist, founded The Land Institute on the prairie near Salina, Kansas. Concerned that modern agriculture destroyed native grasslands, he asked a question that came to define his life: How can we harness the inherent strengths of the prairie ecosystem — the natural resistance of native plants to insects and weeds, the ability of those plants to grow perennially, and their evolved resistance to cold and drought — and marry those traits to the task of growing domesticated crops for food?
Jackson, the recipient of a 1992 MacArthur “genius grant,” set out to create a new kind of farming he called “natural systems agriculture,” which has the “ecological stability of the prairie and a grain and seed yield comparable to that from annual crops.”
