Yes, it is very complex. Another example would be the lack of comprehension that in cold weather regions livestock can only be pastured part of the year. The history of Chicago within its eco-system I am reading makes it very clear that the fact that American farmers were so successful at growing grain cheaply led to the heavy marketing and consumption of "dressed meats" once refrigerator train cars were invented. Once grain was rendered into a uniform product based on grading standards established by the "Change, middlemen were given the power to leach profits from the farmers. The more value and/or unique branding a farmer can add before being subjected to extremely competitive market forces, the more profit he will retain. So, it becomes a question of balancing this with difficulty/cost of somehow bringing product to market through alternative channels.Farm_or wrote:Organic and sustainable are inversely proportional. The lack of chemical control options increases the need for tillage. More tillage= more fuel and worse soil health. Worse soil health=more erosion and more ferilizer...
It would be nice to have a one answer buzz word that we could all support for all situations, but the world is too complicated for that.
One of the main principles of perma-culture is that it should tend towards overall reduction of inputs including human labor. Perma-culture projects can start from any set of initial conditions; hard-packed depleted heavy clay soil urban lot, conventional farm, second growth woodlands, desert, or floodplain. I got into it starting from a set of Mel Bartholomew Square foot vegetable plots combined with an ornamental perennial garden. At some point, due to combination of laziness and aesthetics, I morphed them together in a more free-flowing version of French potager style, which led to an interest in edible perennials which led to an interest in permaculture and foraging. It's interesting to learn about the perspective of people who started from other points on the map.
Good on you. I think any suggested model that is internally consistent is valid. I was not suggesting divvy of 2 acres per human as ideal model, just one based on something vaguely approaching reality. A plan to reduce human population through use of birth control to hunter-gatherer level would also be valid. A plan to carry on with SOP and let God sort it out would also be valid plan for somebody who holds that belief structure. A green-tech robots and space-escape plan could also be valid depending on details. I am interested in theoretical math-based modeling, not moral judgment.Riggerjack wrote:And maybe some kind of birth control, so the entire planet doesn't have to be dedicated to just human survival? I did this math back when I was buying my Whidbey property, and decided I was comfortable with buying up woods and growing trees and some deer. Yes, I took more than my fair share, AND I didn't even have the decency to clear it for crops, but since I am only concerned with the next 50 or so years, future generations can clear it after we are gone.
