Thanks for all the replies guys.
John Elliott, the only tribes I could conquer around the area, are sheep and goats,
they're very stubborn, even as slaves they won't cooperate

.
Jen Shrock, I like the idea of interplanting something useful there, the access to the area could be provided buy
some sort of steps, built using rocks maybe, but that's very challenging to be done, especially when I'll need to link the tallest
walls of rock that you can see from the picture.
Jennifer, thanks for the link, that's what I need, some ideas on how to deal with crazy landscapes like mine. I'd like to plant some
fruit tree and berry bushes on the mountain. I am looking for someone who managed to do this using terracing and raised beds on steep
rocks, exempt for the Inca

. I'll be glad to receive any source of information or thought on this.
THANKS
