I declared an Anthro degree as a way to graduate early, and in grad school for education I decided to learn Spanish to broaden my qualifications which led to teaching English in South America, using the home of a fellow teacher from grad school, a Chicano friend (who got me interested in the cuisine of Mexico) He was later living in Tucson, and my partner and I used his home as a launch pad for two years in Latin America. I came back broke and solo to Tucson and to get gas money to get back to the Northwest, I found myself doing some remodeling work for Richard Felger, an Ethnobotanist.* That led to all sorts of vistas, Long story short: my view of any place on the planet gets rated on climate type and i rapidly assess the geography and culture from that point of view, and as a professional cook with experience in an international restaurant, I've paid dues at a grassroots level. (All of this is just TOO MUCH FUN!) (should it be illegal?)
Wherever You Are I recommend you check out what those who have been there past-to-present have done for subsistence, and give it a try. As an example: Here in the South end of the Willamette, Madia sativa, AKA Gumweed or Tarweed, or "Indian Wheat" a damn yellow composite, (so much closer to a sunflower) is definitely a bioregional star food plant. No summer irrigation needed because it sprouts early and grows fast and ripens small seeds by midsummer. Harvest was traditionally done with a shallow basket and ripe seed heads were tapped with a small stick into shallow, beautifully woven shallow baskets so any chaff or bugs could be blown or fanned away. Seeds were toasted, and boiled in tight baskets with hot stones from a firepit. Add a squirrel or quail and greens to make a rich stew. A hybrid West Coast Cuisine adaptation I devised is to dry some seaweed and make a gomasio for Japanese dishes, or you could do a "sesame snap" thing with sugar syrup, a fine snack for a summer hike or a bit of Xcountry ski travel. Good with a cuppa coffee or some bioregional Black Tea. (yeah, we grow that here too.)
*(I recently had some folks from Tucson track me down for some advice on their Bamboo business in the Tucson area, and sadly, I learned from them that my friend Richard passed on recently, well, Richard, I may see you wherever we go, in the no more than one or two decades as I use up my 9 lives at a faster rate)
