Dear Christopher Burke,
Although most of Europe is probably as much of a "farmageddon" as the U.S. are, I still consider Spain a land of opportunity. It of course depends on your ambitions. I know very little about regulations regarding dairy products and meat but It's likely the EU is even more strict than the U.S. in this regard. There's a lot you can find online about EU regulations (English) and I'm pretty sure it's not going to make you smile. I'm planning to buy a plot of land in Spain and I need to get clear what is and what isn't allowed before signing anything. I'll be visiting Spain February 8-15 with 3 friends and we hope to get more answers than.
I'm from The Netherlands and I'm dying to put permaculture into practice. Unless insane regulations turn out to spoil the fun, it's very likely my friends and I are going to end up in Spain. Our plan is roughly to build soil, gradually live off the land as much as possible and, over time, merge it into a modest business. All financially solid. Interested to team up? Let me know!
And David, chances are we're going to be very close to Catalonia

In fact, the looming independence stopped me from considering to buy land there. The possibility of finding myself outside of the EU one day, isn't something I can integrate into my plans.
Good luck guys! Please keep in touch.
