http://www.energybulletin.net/18645.html For most people, eating organic means a trip to the local whole- foods store and, often, a hit to their wallets. For the Dervaes family, eating organic requires only a trip to the garden. The family of four raises 3 tons of food each year -- enough to supply three-quarters of their diet and maintain a thriving organic produce business to boot.
Jules Dervaes, along with his three grown children, lives on 1/5 of an acre in suburban Pasadena and cultivates about half the property, or 1/10 of an acre. Given that the average American's diet requires 1.2 acres of farmland per person, the Dervaeses are eating quite well off one-fiftieth of the land the rest of us require.
The California Department of Food and Agriculture reports that most California corn or rice farms produce an annual yield of less than a 1/2-ton per acre and the average bean farm 1/5-ton per acre. The Dervaeses' operation is about 60 to 150 times as efficient as their industrial competitors, without relying on chemical fertilizers and pesticides.
"Everybody wants more land," Dervaes says. "We decided to find out how much we could accomplish on this piece of land."
