http://www.yesmagazine.org I got the summer issue recently and it is extremely good.
A rare thing that complys with my beliefs to a large degree.
It is a US publication.
They should be available in librarys if not on the newsstands. It had stuff on alternative currency, "Berkshares" etc, and local currencys are actually pretty widespread but not common. CoOps, human powered machines, etc. Anyway, take a look online. It might appeal to you.
