Aha, that makes sense: smuggling, easy wealth. Well, at least it's good to hear that it doesn't come with the cocaine use problem, or worse, with the territorial battles of those who are engaged in it.
As for land rehabilitation, maybe the native hunter-gatherers got it all figured out: instead of growing human made landscapes, let the forest take over, accumulate all the nutrients above ground, and well... hunt and gather them.
Thank you for all this interesting insight into one of the places I had virtually no idea about.
