agree with pineislander
observation is key.
go at different parts of the day
watch the sun, the rain
see what areas are damp, dry, shadow, full-sun etc...
generally, you would want to put larger trees on the North side
but take into account species and growth.
personally, i would start out with planting hundreds of fast growing nitrogen fixers.
maybe creates some swales, especially if you have dry areas.
and i would pick half a dozen income plants, and plan to inter-plant them.
(nut trees, cacao, litchi?)
fast growing species like papaya can offer food and income. seeds are cheap.
and will provide biomass when they die or get shaded out by larger species.
and yeah, i would build 2 houses ASAP and get some people in there to help.
talk to the locals, you just might find a guy who knows the best species to grow
how to do it, and maybe he needs a place to live...
and if you need someone to give you a hand for a *good 2 hours* a day
(for free fruit) i would be happy to help
Actually
there is a guy named Jagannath
who has been in several countries learning Permaculture, by renovating large sections of land.
He also teaches permaculture. ive learned a lot just from watching dozens of his videos.
He is intelligent, and obviously learned a lot, but is also very hands-on.
