Partnerships in "handmade urbanism"

An excellent and thoughtful review of Handmade Urbanism: From Community Initiatives to Participatory Models by the Project for Public Spaces notes the importance of partnerships, especially cross-sectoral approaches:

The case studies, all of which were selected through the Urban Age program, highlight a wide variety of interventions in slums and favelas in Mexico City, Istanbul, Cape Town, São Paulo, and Mumbai. Presented together, they lead the reader on a journey through a potential place: a city where public spaces truly belong to the public, and everyone is encouraged to contribute. The analysis of these projects looks at each city through a five distinctly different lenses, discussing the role of citizen-led projects with community actors, government officials, academics, artists, and intermediaries, defined by the editors as “those operating at the middle level (between top-down and bottom-up interventions) intermediating scales, and different layers of knowledge and action.”

Unsurprisingly, given this staunchly multidisciplinary approach, there is a heavy focus on the role of partnerships in driving success with bottom-up projects. The success of any public space relies heavily on a strong network of partners, from individuals to organizations. This is especially true of citizen-led projects because unsanctioned improvements often require substantial public support to avoid being dismantled for any number of bureaucratic reasons once they are discovered. Thus, almost every case study presented in Handmade Urbanism involves some interesting examples of people from different constituencies working together. More importantly, several illustrate the power of partnerships and collaboration to transform and expand the reach of the groups that participate.
