The minimum amount of agricultural land necessary for sustainable food security, with a diversified diet similar to those of North America and Western Europe (hence including meat), is 0.5 of a hectare per person. This does not allow for any land degradation such as soil erosion, and it assumes adequate water supplies. Very few populous countries have more than an average of 0.25 of a hectare. It is realistic to suppose that the absolute minimum of arable land to support one person is a mere 0.07 of a hectare–and this assumes a largely vegetarian diet, no land degradation or water shortages, virtually no post-harvest waste, and farmers who know precisely when and how to plant, fertilize, irrigate, etc. [FAO, 1993]

A much better equation is:
<People = Other People> and "other people" implies that something is going to be coming your way from outside your <food = land> system. So, it's just a matter of how well you are able to build and nurture the connections that allow a small amount of land to produce the "seed money" to kickstart this other equation.

I agree Garrett.
garrett lacey wrote:Right. I just did some more light reading on calories and as far as i can tell, i consume a fair bit less than the recommended caloric intake of someone of my size. I am pretty active (physical jobs, walking/biking everywhere) and i am not losing weight.
However, i really dont enjoy thinking of my food in terms of calories. I'll just keep trying to maximize the productivity of my spaces, and eat what feels right i suppose.

The Facts and Stats page is inspirational.

1.67 additional acres is enough to graze and produce winter fodder??
Graze and produce winter fodder for what, where? It takes 20 - 50 acres to graze one steer in my region.
