Something like the Vietnamese VAC (garden/pond/livestock) system[1] is the ideal in terms of efficiency and complete nutrition in my opinion: > In many villages, 50-80 percent of families have the full VAC system. Figures show that 30-60 percent of income of most village families may come from the system; in many cases, it may be 100 percent. > The pond is constructed close to the house so that the domestic and kitchen wastes are drained into the fishpond. The livestock pens and garden are also situated near the pond. The 1000-5000 m2 garden includes a variety of vegetables (i.e. green onion, sweet potato, watercress, etc.) and fruits (i.e. banana, orange, peach, apricot, etc.) and other crops, including sugarcane, tea and cassava. This provides a mix of perennial and annual crops. This is all on generally less than an acre (1 acre = 4000 square meters)! Fish, crops, and livestock in one self-contained system.
