hi christamone,
I live in the Netherlands,
permaculture had a slow start here but by now is gaining, especially because of the transition town movement which is based on permaculture and evolved from a permaculture design school in Ireland.
Social, political and economic factors probably all have an influence on the development of permaculture in a country. Also very important is how much gardening/growing food on small scale is embedded in a culture. I guess in England almost everybody used to do a bit of
gardening, even if just in an old shoe.
Portugal and Bulgaria also have a widespread
gardening culture. The Netherlands however are very densely populated. Almost all of the
land has become an agglomeration of cities connected by suburbs. and then i don't mean US type suburbs with big houses and gardens, i mean densely built neighborhoods with little green and if u have a garden even, its small.
The Netherlands where one of the first countries worldwide that stopped getting their produce from their own land but importing most of it, we've been dependant on international trade for so long. The production of our food and other products has been so totally externalized, it is so far away, and we've lost any understanding of it.
those things don't help. but things are starting to develop.
the main difference i can make out from hanging around on this and other international forums is that in Europe the mainstream permaculturists are (so to speak with Paul Wheaton) 'holmgrenesque' and in the States its more
Sepp Holzer permaculture (or that might just be the tendency of this site).
In Europe for example, things like a possible
energy crisis, oil depletion and climate change are subjects discussed at a lot of
pdc's. Also i seem to find little on urban and small scale permaculture from US sources, while in Europe where land is extremely expensive, big permaculture sites are a bit rare (although there are some great places in Spain and Portugal).
