Clemson University has a Sustainable Agriculture Program. One of the projects under this program is the Urban Permaculture Instititute of the Southeast on a 1/2 acre lot in the middle of the Walterboro, South Carolina. The lead on the project is Shawn Jadrnicek who practices permaculture with chickens, fish, bees, food forestry, vermiculture, insect production, greywater systems, passive solar, mushroom production, rainwater catchment, floating hydroponics, and a partial hydroponic systems.
From their site:
Shawn Jadrnicek started the landscape in 2006 by installing edible perennials that he propagated. He currently has over 50 edible plants growing in a polyculture food forest system. The aquaponics system was created in the spring of 2007 and stocked with tilapia, Gambusia, bass and crayfish. Shawn Jadrnicek is a horticulture agent with Clemson Extension Service. He created the site to give a visual demonstration of permaculture design concepts, provide his friends and family with food, and prepare people for the peak oil crisis.
