Urbanism as a shared, bottom-up process, is an historical evidence since the beginning of civilization. It follows natural patterns belonging to the intrinsic logic of space.

Proposing a peer-to-peer urbanism approach today, has deep implications, not only about the very discipline, but about society and politics. Thus, it requires a serious study, that we are carrying on together with our friends of P2P Foundation and Cityleft, under the supervision of Agatino Rizzo.

Here a brief history of P2P Urbanism, by Nikos A. Salingaros and Federico Mena-Quintero.

At this link you can find the first P2P Urbanism World Atlas, listing P2P urbanism initiatives in the world. On that same webpage you can register to the P2P-U mailinglist, and participate in the process of defining P2P Urbanism and signal new P2P-U initiatives to be put on the Atlas.

Down here a definition of P2P Urbanism in English (translations in other languages will follow asap). As this is a participated work, this is the 7th version, that can be modified and integrated.
