sustainable food - people per acre of food


How many acres does it take to sustainably feed one person when there are no other inputs. No manure, no compost, no animal feed, no fertilizers ....

Helen Atthowe shares her experiences of growing enough food to cover 75% of her own food needs plus enough to sell at the farmers market. Based on years of experience, she attempts to estimate how many acres she would need to feed herself if she has to grow her own fertilizers. Helen's perspective is dominantly rural.

Norris Thomlinson and Tulsey Latoski have carefully measured the production of food from their urban lot. They have optimized the food production a lot, and have some ideas on how to optimize it more. The also compare their initial expectations to the results they experienced.
