Ehm, that's not specifically of Swiss, nor Canton Ticino, in the whole world we have used for centuries "advantageous micro-climate places", sometimes even for living, sometimes just to preserve foods or something else, sometimes thanks just to specific orography, sometimes artificially made with various design. We talk about that now because of the looming crisis and a kind of (largely absurd) "what we can do with nothing tech", generally forgotten that we do not produce foods locally, like in the past, so even re-learning long lost or long-marginal tech and techniques we simply can't do much with them... Honestly: if someone is warred by loss of electricity == loss of fridges/freezers a small p.v. or other personal renewable is the option so far, learning to cook and preserve at home is another, but going further is not a realistic option.
