Nen is right.

You won't make a living from your crops, you probably won't be allowed to put new dwellings up if it's the same as in Catalonia, and you probably will pay more for your land than it is really worth!

Having said that, many people buy land here for the lifestyle they can have, for the sunny climate, the laid back way of life etc.

It's not all about making money. I know that if I sold my land now, I would get less than half of what I paid for it 7 years ago when land prices werre much higher and crops were worth more.

I sometimes burn my crops in the log burner! Why you ask? Simple.. logs cost much more to buy than I can get for my almonds.  If I sell my almonds and spend all the money on logs I will be out of pocket. The almonds burn like wood, and cost far less!

Most of the time though, I just let them fall to the floor and let them rot. It really isn't worth investing the time or money to harvest them. Harvesting by hand is a back breaker and investing in the equipment to do it mechanically will cost more than you will likely  recover in your  lifetime!
