I think I can narrow down the list of skills I collected in the data selection a lot if I'm willing to live at a lower standard of living. Really all you need is a hut and a garden, or a hut and a lot of acreage. Food storage is necessary if your growing grain. I've narrowed it down to what I want by category here, with occasional explanations of why I chose each element.

FOOD:

Permaculture - move towards lower maintenance practices
Aquaponics - several ponds will be nescessary anyway
Seed saving - nescessary for sustaining production
Compost - better to use the waste than not
Mushrooms - are tasty and easy
Foraging - if there is enough land
Greenhouse - if I can make glass or some equivalent
Irrigation - probably by hand or flooding, not sure I can make pipe in quantity
Soil fertility - very important
Mulching - weeds are half a gardeners work

Animals - animal products are far easier in the winter
Bee Keeping - for pollination, honey and wax
Small grazers animal husbandry - maybe, not sure I want meat or milk enough yet
