I randomly stumbled upon something called “Solidary agriculture” yesterday. People come together, pay a monthly price to keep a farm running. This makes the farm independent from draughts, bad harvests etc. In return for the money you get fresh produce throughout the year, no price fluctuations, you always get what was produced. Sometimes more sometimes less. If this isn’t Solarpunk I don’t know what is. It’s pretty easy as well, provided there is an initiative like that in your area.
