Hi Shaun

It depends on how self-sufficient you want to be.

1. 30-50 per cent self sufficiency
   veges (some bought in)/ berry fruit/ compost area and pathways
   = 54 metres squared per person
   
2. 50-80% (including above)
   all veges are grown in the garden
   potatoes, fruit and cereals are purchased as are dairy products
   garden beds are intensively used and planted
   = 73 metres squared per person
   very intensive growing + rotation + green manure crops
   = 100 metres squared per person
   
3. 80-90% (largely vegetarian diet)
   all veges, berry fruit, fruit, cereals, pasture for sheep and goat, fodder cereal, compost area and pathways
   = 820 metres square per person
   
   If option No. 1 is chosen, 100metres squared x 150 people
   = 15,000 metres squared
   = at least 1.5-2 hectares per community
