Hello, Permaculture makes sense to me in biological terms, and I am currently in the market for a piece of land on which to practice sustainable agriculture. The body of information about how to do that is rich and diverse. However, I wonder how viable permaculture is for supporting my family. I know we could probably feed ourselves from our land, but I am not sure about producing and selling enough product to pay taxes, the mortgage, insurance, cell phones, internet, clothing, orthodontia, college savings, and all the other costs of family life. I am looking for land at about 40 degrees north latitude, at high altitude (1,600 to 2,700 meters (5,000 to 9,000 feet) above sea level), with a semi-arid climate (28 cm to 58 cm (11 inches to 23 inches) of precipitation annually. Temperatures range from -23 degrees celsius in the winter (-10 Fahrenheit) to 37 degrees (100 F) in the summer. I'm not worried about the climate. Techniques abound for dealing with the elements in a sustainable manner. The question is, how to create a situation that will financially sustain a family, as well?
