I guess I just find the topic (just) out of scope for what I thought was the topic of equipped.org - survival preparedness for time-limited events and disasters. If your scenario challenges me - or us - to go live off the land for a year, that entails a significant general calamity or personal disaster. It makes a difference to know which one you mean. If I am burned out of my home, I find another one. If the 9.0 quake hits my area, I may move to another area. Its doubtful anything short of a nuclear strike - in which I as a survivor count myself extremely lucky (or not) to continue breathing - could cause me to migrate and start living off the land, and that seems a decidedly survival-ist scenario. There aren't many scenarios where I would either abandon the comforts of civilization or go back to the land on my shy half acre, which is presently unsuited to cultivation. Poverty alone doesn't make me a farmer or return me to migration.
