From Artist Douglas Gayeton : www.lexiconofsustainability.com

I do agree with the idea that local and real knowledge is more important than only organic certification. When ever possible I prefer having not only a familiarity with the farms and farmers that am working with but also certification papers as well. Being certified small scale shows a commitment / investment in the sustainable and organic farming movement. Many people/businesses are interested in profiting from branding their product  “Organic” or “Local” without being consistant in their practices, so being as thorough as I can seems quite sensible. I encourage you to do the same, ask questions get to know your farmers and when you find producers/businesses who are really honorable support them!
