A long-term historical perspective of urban growth in Europe and the US

Marcelo Medeiros (who is secretly my guru) pointed me out to two papers on a long-term historical perspective of urban growth, by Rafael González-Val. I imagine some readers of the blog might find them  useful  interesting.

• The Evolution of US City Size Distribution from a Long Term Perspective (1900-2000)
• Historical Urban Growth in Europe (1300 - 1800)

ps. The AAG was great with some really good thought provoking sessions. I'm still in the Bay area for two more days, visiting the team at Berkeley Urban Planning to talk about transportation and accessibility modelling using Pandana .

On my way to San Francisco

The blog will be a little less active in the next few days as I will be at the AAG in San Francisco. I will be presenting the second paper of my PhD (details below). Anyway, in case you're in SF next week and want to reach out and grab a  coffee  beer, you can drop me line or a tweet.


Session: Mega Event Planning for Sustainable Legacies

Mega-events, transport legacy and the redistribution of employment accessibility

Rafael H M Pereira

Abstract:

A growing number of studies have discussed how mega-event strategies to fast-track urban development in host cities are commonly backed by pro-growth discourses, which rely on the assumption that all local residents equally benefit from the trickle-down effect of economic growth and infrastructure investments. What has received much less attention in the literature, however, is the discussion of transport legacy, and particularly the distributive aspects of who benefits from the new transport infrastructure developments once they have been put in place. This paper discusses the social impact of transport legacies in terms of how such developments affect the transport accessibility to job opportunities of different social groups in host cities and whether local governments mobilize these events to reinforce or redress existing patterns of urban inequalities and segregation. As a case study, we analyze Rio de Janeiro (Brazil), looking particularly at the transformations carried out in the city’s transport system in preparation for the 2014 World Cup and 2016 Olympic Games. We make a before-and-after comparison of Rio’s transport system, calculating employment accessibility changes that have resulted from these new investments between 2013 and 2016 and compare how accessibility gains vary across different social groups and areas of the city.

Urban Picture

This is a picture of Vila Amaury, a temporary village of 16,000 people in Brasilia - Brazil. Most of those people were construction workers who built public buildings in the city, including some ministries and the National Congress, the tall building you see in the picture. (ht Telmo Ribeiro)

The village was later covered by the water when the Paranoá River was dammed to create an artificial lake.
