>>1572753It's in principle just a method to design projects in a certain way. You follow simple steps
observation -> analysis -> design -> implementation -> maintenance
Then repeat
The designs are trying to mimic natural ecosystem functions, to create a cultured landscape that is providing for humans needs while being an flourishing, diverse ecosystem at the same time.
It is a legit method to turn our shitty urban sprawl, industrial monoculture and growing desert world into an endless lush and abundant food forest that supports the humans taking care of it indefinitely.
We got all the methods for it, what is missing is using it on a large scale.
Also loads of hippies using it on a amateur level without sight of the economic viability give it a bad name. If you want to learn, try to not get into that too much, but look at projects that are actually supporting themselves with it.
>>1572815There's lots of ways to make money with it. The people who fail at that don't try to begin with or are bad at making marketable products and finding costumers or get fucked by laws and regulations.
You can grow all sorts of high value crops that nobody else bothers with and direct market (for example to restaurants).
This is something that you have to account for in your design. If you fuck up, most likely your design was flawed.
