I would aim to become 100% Water sustainable, 100% food Sustainable & 100% energy sustainable within 2-3 years. I would follow the 3 ethics and use mainframe permaculture to dig the initial swales and dams and start in on agroforestry and production of
compost (there is never enough). Within a year I would try and have quality demonstration examples of everything from herb spirals, various composting techniques, chicken tractors as well as core permaculture technologies (passive solar, mass rocket, Jean Pain mounds, bio-construction etc). If the site was large enough I would design it into paddocks and start a paddock shift system, starting with chickens and then moving up into larger animals. I would also look into
aquaculture opportunities on the land. Once I was confident with the demonstration examples, I would try and start a local permaculture chapter and host meetings once a month to encourage local permaculture growth. I would also offer 1 day and weekend courses on composting, agroforestry, intro to permaculture etc as well as offer Brasilian and English PDCs. I would also market the crap out of the site to try and get volunteers and woofers. Dependent upon where the surplus in the system occurs, I would follow niches and try and make some cash to pay for equipment and expansion.
Of course, that is what I would do if I had the land, some initial funds to pay for the earthworks and establishment of the system. What would you do?
