In the table below, "Cals/day" and "Oz/day" give the number of calories and the number of ounces one person would consume on average each day. "% of diet" gives the daily caloric consumption as a percentage based on 2400 total calories per day. "Qty req" gives the total number of trees, poultry, etc required to feed 10 people 2400 calories each. "Land" gives a rough estimate of how much space would be needed to provide 10 people an annual yield sufficient for 2400 calories/day using this category as a monocrop (not integrated with other foods).
So the total land required to feed 10 people is about 1.5 acres for the plant portion of the diet in zones 1 and 2 (and maybe 3). I'm making some big assumptions here about being able to fit the chickens into zones 1 and 2 with no additional space required, and bigger assumptions about keeping goats in zones 2 & 3 with goat walking in zones 4 & 5.
|Food type||Cals/day||% of diet||Oz/day||Qty req.||Land||Notes|
|Goat milk||400||16.5%||9||4 full-time does + babies||Integrated into zones 2&3, and walked through 4&5||2 1/2 cups milk/person/day|
|Goat meat||35||1.5%||1||4? babies per year yielding 260 lbs hanging weight?||Integrated into zones 2&3, and walked through 4&5||Very unsure of realities of how much goat meat we'll get as a byproduct of keeping does for milk|
|Eggs||250||10.5%||6||50 hens + 4-8 cocks||Integrated into zones 1&2||3 eggs/person/day. Mostly chickens, some ducks|
|Poultry meat||40||1.5%||1||Culling 50 hens & cocks per year||Integrated into zones 1&2||Based on hatching 50 new eggs each year to replace the 25 oldest layers and then culling 25 young cockerels. We could hatch out more eggs specifically for meat|
|Fruit & berries||250||10.5%||~16||11-25 trees||10,000 ft²||Assume 20' to 30' spacing on grid. Assume 1/3 lb/ft²|
|Avocado||275||11.5%||8||12 trees||11,000 ft²||Assuming 21 lbs/100 ft² and 30' grid spacing|
|Coconut||300||12.5%||5||~46 trees, tall & dwarf||20,000 ft²||Uncertain of #s. Assuming 30 lbs per plant, on 21' spacing in square grids|
|Bananas||165||7%||9||50 plants||7,200 ft²||Assume 12' spacing on grid, and 40 lbs/100 ft²|
|Nuts||300||12.5%||2||15-30 trees||11,000 ft²||Spacing from 20' to 30' affects # of trees|
|Starchy crops||300||12.5%||16||7,000 ft²||Assume yield of 1/2 lb/ft². Start with taro, sweet potato, cassava, yam, squash; phase out once tree crops of breadfruit, malabar chestnut, etc start bearing|
|Greens||40||1.5%||4||1,000 ft²||Assume yield of 1 lb/ft², between beds and foraging greens from other parts of the system.|
|Honey||45||1.5%||.5||2 hives?||10 ft²||Assume 60 lbs/honey/hive/year|
|Grand total||2400||100%||4.85 lbs||67,200 ft²|
I would expect to fence the chickens and goats out of about 8000 ft² of zone 1 for the greens, berries, and starchy roots.
