The Social Fabric of Cities




Vinicus Netto (Twitter) has published a new book called 'The Social Fabric of Cities' (contents and introduction available here. There is also a website of the book). This one is going straight to my reading pile and I'm sure it will be of interest for all the 100 million readers of this blog. Here are the foreword by Mike Batty and a description of the book.


Foreword:

"Linking the physical to the social city is the challenge of our times. This is one of the first attempts to systematically do so, and Netto brilliantly succeeds in showing how encounters, segregation, movement and interaction are reflected in our understanding of the form and function of the city." (Michael Batty, CASA, UCL)







Book description:

Bringing together ideas from the fields of sociology, economics, human geography, ethics, political and communications theory, this book deals with some key subjects in urban design: the multidimensional effects of the spatial form of cities, ways of appropriating urban space, and the different material factors involved in the emergence of social life. It puts forward an innovative conceptual framework to reconsider some fundamental features of city-making as a social process: the place of cities in encounters and communications, in the randomness of events and in the repetition of activities that characterise societies. In doing so, it provides fresh analytical tools and theoretical insights to help advance our understanding of the networks of causalities, contingencies and contexts involved in practices of city-making. 
In a systematic attempt to bring urban analysis and research from the social sciences together, the book is organised around three vital yet relatively neglected dimensions in the social and material shaping of cities: (i) Cities as systems of encounter: an approach to urban segregation as segregated networks; (ii) Cities as systems of communication: a view of shared spaces as a means to association and social experience; (iii) Cities as systems of material interaction: explorations on urban form as an effect of interactivity, and interactivity as an effect of form.

Inequalities, cities, big data, transport and health

These are the core issues covered in five special issues of top journals this year, what I think reflects how these topics and particularly cities and social inequality have gained strong momentum in recent years.

Quote of the Day: progress

Sean Illing: What would you consider the most dangerous idea in human history?

Tyler Cowen: The idea of progress. ... Well, we're all for progress. It's easy to say the most dangerous idea is evil or racism or genocide or murder, but those ideas tend to persist only when they're packaged with some notion of progress. Progress, for all of its good, brings us new technologies and threats against which we can't deter, environmental problems, biodiversity loss, and so on. That we cannot avoid believing in progress may also prove to be our undoing.

Empty spaces in the crowd: Residential vacancy in São Paulo

Nadalin, V., & Igliori, D. (2016). Empty spaces in the crowd. Residential vacancy in São Paulo’s city centre. Urban Studies, DOI: 10.1177/0042098016666498.

Abstract
In the past decades, when São Paulo became the national manufacturing centre, it has experienced great population growth. Since then, many housing problems have emerged. In addition, the difficulties that inner cities face in attracting jobs and maintaining economic activities are particularly challenging. Indeed, even if many cities have successfully regenerated their central areas, the so-called inner city problem is still very much alive in the case of São Paulo. As a result although the city centre has abundant urban infrastructure it still has plenty of vacant spaces, including residential buildings. One could say that São Paulo’s city centre is characterised by a large number of empty spaces in an area that is simultaneously crowded with buildings and urban facilities. This paper intends to contribute to the empirical analysis of the determinants of vacancy rates, with a particular focus on historical city centres, using São Paulo Metropolitan Area as our case study. Our empirical analysis relies on district-level data for the years 2000 and 2010, and combines standard spatial econometric methods with hedonic modelling. Our results suggest that there are three main groups of determinants: individual buildings characteristics, mobility of households and neighbourhood quality. We find evidence that the historic central city is a distinctive submarket, needing special urban policies. Its determinants work differently when compared with the housing markets of other areas across the city.

#wherearetheracks in Cambridge ?

I took this picture yesterday near the train station at Cambridge UK. I confess I'm surprised with how poor is cycling infrastructure in Cambridge given that this is the city with the highest share of commutes by bike in Britain. Without much ambition, I'm starting the hashtag #wherearetheracks in Twitter to raise awareness of local authorities about the lack of cycling racks in their communities.  

This is the least that happens where there is a lack of cycling infrastructure.
