For example, if your plot of land were all of North America, the cities would be zone 0, and the designated wilderness areas of Canada, Mexico and the U.S. would be zone 5. Clearly you'd want to get more food production into zones 1 and 2, but beyond that...
You'd have some extremely dry and extremely wet areas. Where would you put the swales, and how big would they have to be to recharge the aquifers, etc.? Or would you pull a Sepp Holzer and turn the entire Missouri river into a big lake?
What other crazy decisions would there be to make if we considered a whole continent as a single project?
I live in Europe so I can only generalise without specific references to the American situation:
I wonder if design at the scale of an entire region or country (let alone at the scale of an entire continent) can still be called permaculture design. I suspect it would require enormous central planning and harmonising of local interests & needs.
Central planning is not unfeasible, and we have examples of planning of this scale in some parts of the world, like in China, where canals or - more recently - mega dams were built, or forests planted, to alter the ecology of large tracts of land, for good or for bad. The problem with this type of macro planning is that it is often FORCED to disregard the interests of small communities which are then negatively affected. E.g., whole villages have to be moved when the mega-dam is built, crop fields and gardens are submerged, etc. etc.
If you think in terms of permaculture "zoning", then on a large scale, you will unavoidably end up with a myriad of zones 0/1 (farms, homesteads, villages, towns, cities). Any
permaculture design will need to take into account this multitude of human settlements and their needs. So there isn't a
single zone 0/1. As a result, the settlements and local communities - rather than the "country" or the "continent" - are / should be the basic unit of permaculture design. So then where do you start if you need to "design the whole country / continent?
Having said that, there are certain "crazy decisions" that could be made at a national level:
- pass laws that make the following things
illegal: front lawns and golf courses; development of flood plains of rivers and streams; ploughing fields and leaving them without vegetation cover during winter; etc. etc etc.
- start a nationwide programme for reforestation of slopes, watersheds, and areas threatened by desertification,
- pass laws that make it
compulsory to have a built-in rainwater collection system for any man-made impervious surfaces such as parking lots, tarmac roads, and roofs
- etc etc etc - the list could go on and on
