This document discusses soil, agroecosystem, and landscape health as it relates to sustainable food production. It covers topics such as soil health being the basis for sustainability, agroecosystem health through mimicking natural systems like the slash and mulch system, and landscape health through connecting agroecosystems. Case studies are provided on projects taking a landscape approach like the Nature Conservancy's Cosumnes River Project. The overall message is that sustainable food production requires restoring soil, agroecosystems, and the connectivity of the landscape.
