Lasse has lived on 50 euro a year, by sustainably managing the land. He has written articles and they are freely downloadable here:
I remember you. You were talking to me about some Hirvitalo things. If you like to use my and my wife's articles about self- suffiency, you can use them freely, eg. put them into appropedia. I'm storing my stuff at www.rihmasto.fi/artikkelit. You can download them there. Spring is arriving and practicel work is calling. Have a nice spring!
