Manuel Castells Talk on the Implications of Networks on Urban Planning

Posted: March 23rd, 2008 | 1 Comment »

In a talk at the Responsive City meeting, Manuel Castells discussed the practices of urban management and design in this current historic moment when 50% of the planet population now lives in cities (South America reaching 80%!). Unlike what futoroligsts predicted communication networks did not kill distances the cities have not disappeared. It lead to new form of urbanism – some call it megacities (Casstells has another word about that) or what Peter Hall and Kathryn Pain refer as Polycentric Metropolis, a cluster of cities and towns, physically separate but intensively networked in a complex spatial division of labor. These new places are represented by networks (like new england, southern california) and they do not have official names. In fact the name are defined by the news and media. For instance local news refer to the “Bay Area” in San Francisco (a region where San Jose is even bigger) and “South Land” in Los Angeles. In these cases, the television market (and how it attracts advertisement) actually defined the place.

Globalization is made of these networks. Each network has a different geographies (movie industry, knowledge production, finance). In some metropolitian areas these networks overlay (e.g. London) and synergies happen at the nodes where theses different networks connect. They form “micro-milieux” where decision making takes place. For instance, the city of Saragossa is currently being integrated to Madrid and Barceona in the same time. As Barcelona made less efforts in interconnecting, apparently Saragossa is becoming absorbed as a spatial node of Madrid.

There is not political authority over these new places (megacities). The expression of people on their major metropolitan areas (see Un point de vue unique sur la ville) reveals that they feel betrayed by their local governments because they favor the management of the flows over the management of the place. It means that the strategy to first get rich by privileging connections to the outside world (investiement in airport, optic networks, convention centers) and then we redistribute the wealth is not well perceived. Saragossa is an excellet example of these tensions between existing in the world and providing basic or good services to citizens.

Castells gives some key pointers that now must be considered in urban planning:

  • connectivity is critical (multi-modal, local and global connectivity)
  • speed and scale create huge environment problems. Technologies make cities grow and do not make them disappear (as also stated by Richard Florida, “the World is Spiky“. On some city maps the freeways are now drawn in green. Therefore, environmental planning should the at the foundation of planning.
  • crisis of political legitimacy. citizen are more distrustful from local governament than the central authorities.
  • the public physical space is really hard to maintain. Some of them, like La Rambla became a theme park where locals are not present anymore (even the mimes and entertainers are foreigners).

and a few implications in the management of these spaces:

  • strengthen of the public space in each of the nucleus
  • aim at congregating people with no specific purposes (serendipty) shopping centers are not public spaces. merchants streets are public spaces
  • metropolitan cities are about building “stations”. For instance, the most innovative places are close to railway stations. We have to think that we must build cities around these nucleuses.
  • density of population creates possibility for stores, business and life emerges (following here the Barcelona Ecologia’s concept of compact mediteranean city)
  • maintain a vibrant immigrant life (letting them to be open the whole night). Like stores owned by Chinese immigrants in Spain.
  • nurture the notion of distributed monumentality. Build spatial signs of recognition, otherwise people don’t know where they are. It can take the form of monumental architecture (whit the same usual suspects designing the monuments (Nouvel, Gehry, Foster, …- cities are divided by serveral architectural agencies). These monuments become signs of indifications are more important than their actual settings.

Relation to my thesis: Even though I do not focus on macro/global issues of the development of networks, I was curious to hear how a leading urban sociologist describes the hybridization of the physical and digital in the city and the type of signals he analysis and how they are transformed in implications for planning and management. From Castells’ talk, it seems that the interface with technologies and networks is still not taught in land use planning and urban design. It once again comforts my feeling that urban space will need researchers with mixed competences in engineering, HCI (call it user experience or interaction design) and urban planning, validating this year’s move to the MIT Department of Urban Studies and Planning.

In relation to the notion of “distributed monumentality” and their necessity as spatial signs of recognition, I believe that the analysis of pervasive user-generated content could reveal the monuments of the city that people use to anchor their data in the space.

    As a writer on public art and public space, I am interested in more information on Castells thoughts as you described below. Do you know which book or text?
