The city itself is perhaps the most complex shared resource for its inhabitants. Yet, it is still designed as a place where the public/private divide is predominant and governed by public institutions designed as Leviathan-like institutions which negotiate urban development mainly or solely with private stakeholders. One of the problems with this model of urban and governance design is that the decline of public financing and cyclical real estate and fiscal crises have forced cities to struggle to prevent urban shrinking or gentrification processes, as well as to support and maintain shared resources and common goods or regulate urban development to keep cities as a fair, just, diverse, human flourishing and creative environment. This has left an opening for other forms of governance to emerge, going beyond the public/private dichotomy, raising anew the question of the appropriate type of urban infrastructure, urban land taxation, city planning decision making process and other urban governance design issues. Are there other models to design or re-design urban settlements and other governance solutions to manage cities themselves as not just market-friendly, but also as human-friendly urban collaborative commons?
