Hey, I lived on the big island for a few years and was involved with several of these types of backyard systems. We lived on the wet side of Waimea which might be one of the best climates in the world for this. In about 2 years we developed a really great backyard system full of
native plants, canoe crops (Polynesian introduced food/medicinal crops), and animals (ducks,
chickens, pigs). This was on a 1 acre rental property (shared with owners), and they were happy to allow us to experiment and stuff. Here’s a video:

I was just there visiting them and the system is running great with minimal maintenance. You might be able to visit it but if not I’ve documented it pretty well on my Instagram (@geoscience_ecology_hawaii) and am working on uploading some videos of that system in the next week or two to my YouTube channel (
https://youtube.com/@AgroecologicalSystems) Hopefully that content is
enough to give you a sense of what it’s like.
Another great location is Honoka’a / the Hamakua coast. I have a friend who bought a 6 acre property there and is in the process of turning former pasture into a food forest. He has plenty videos on his YouTube channel ( [youtube]https://youtube.com/@ainabearfarm8075),[/youtube] and might be willing to give you a quick tour. Definitely a good climate for this type of work, plenty of soil, etc. He’s specializing in rare fruit
trees.
Big Island has an insane variety of climates and different soil conditions. A lot of off-grid folks live on the hilo / Pāhoa side, cheap
land but very thin soils on porous lava rock make it a challenge to work with. I have a friend there who is trying to develop soils in raised beds and he is able to make it work pretty well, but if you’re really in to growing things it might not be the best site.
