>Is difficult is it to truly adopt a permaculture-dependent lifestyle? It takes a lot of dedication, hard work and experience. If you know what you are doing, you can be self sustainable within a short time frame, if you are new and stumble your toes on practical issues, you will struggle to get things running smoothly, especially if your designs are unrealistic for some reason...
>How long does it generally take for the land to start producing optimally? Depends on production systems and inputs of labour, material and investment. It is possible (but hard) to make a project economically viable within a year or two with the right methods and lots of input. If you are limited, which is very likely, you will need some years until your system is in place and matured enough to yield sufficiently.
For example: the trees in a forest garden might take 10 to 30 years to create real abundance, but you can always bridge that gap with faster perennials, annuals and things like mushrooms and animals.
>More importantly, what is the optimum number of people needed to get a permaculture-lifestyle to truly flourish (assuming everyone is contrabuting)?Again, depends on the systems you want to realize, what ressources you have access to (land, structures and material), the skills that people are bringing in...
In the end, it all depends on how good your designs are. This is actually all permaculture is: a design method. If something is not working out, you generally did not pay enough attention while observing and making your plans.
If you can give me some more details about your vision, I could try to help you get into the right direction of give you an idea or two of things that could work out...
I will try my best to answer any questions you may have.
And if you are serious about it, make a PDC and connect to people practicing permaculture in your area.
