Unveiling Urban Sprawl in the Mediterranean Region: Towards a Latent Urban Transformation?

The relationship between form and function in European Mediterranean cities has been widely addressed from various perspectives. A number of studies indicate that, until the 1980s, compactness was a key trait of several cities of the Northern Mediterranean. However, after the ‘compact growth’ period, these cities experienced patterns of urbanization that differed from their traditional trends. Since the 1990s, sprawl, coupled with population decline in the inner cities, has become the main pattern of urban development. This article explores the key features of exurban development in the Mediterranean region in order to provide material for a discussion based on the differences and similarities in the characteristics of sprawl processes originating in the US and Northern Europe. It concludes that any debate on policy responses to sprawl must be specifically formulated according to the scope, administrative level, housing and planning system, territorial and socioeconomic characteristics of the urban system under examination. It is our belief that sprawl requires site‐specific analyses and policy strategies for the region being studied if the process is to be effectively controlled.

Making the ‘Invisible’ Visible: Redevelopment‐induced Displacement of Migrants in Shenzhen,China

Gentrification in China is intertwined with urban redevelopment, which causes the large‐scale displacement of rural–urban migrants from ‘villages in the city’ (ViCs). Because of the informality of ViCs, migrant renters have very insecure tenancy and during redevelopment they are treated as a negligible (‘invisible’) social group. As they are very difficult to locate after displacement, they are also literally invisible to researchers. To make the invisible visible, this study traced a sample of displaced migrants from Huangbeiling village in Shenzhen. The focus was on the displacement process and on identifying the consequences for the displaced. We found various forms of displacement during the redevelopment process. Nearby ViCs were prioritized by displaced migrants to minimize as much utility loss as possible. However, they generally suffer from decreased proximity, increased living costs, and the loss of social networks and job opportunities. Remarkably, some choose to return to the gentrifying village, enduring displacement in situ caused by increasing rents, drastic physical neighbourhood changes and declining liveability, in exchange for retaining their original social and economic networks. Large‐scale urban redevelopment is causing the rapid shrinkage of informal housing. Recognizing and addressing the housing needs of this impoverished social group is a matter of urgency.     

Urban Politics as the Unfolding of Social Relations in Place: The Case of Sexually Transmitted Disease Investigation in Mid‐Twentieth‐Century Gay Seattle

Recent debates in urban politics stress the need to broaden conceptions of what counts as urban politics, as well as of where they take place. This means shifting attention to include more quotidian and prosaic social relations, including those taking place in spaces of civil society. We answer this call with a case study of the relations between an emerging gay male community in mid‐twentieth‐century Seattle, USA and the local public health department’s disease investigators (DIs). We focus on both the biopolitics and cultural politics of the investigation process, from the perspectives of both DIs and gay men. We point out certain tensions and paradoxes in these processes as a form of governmentality, and interpret them through a ‘noir’ cultural lens that is consistent with a notion of urban politics as the unfolding of social relations in place. We conclude by stressing how our findings and framework can augment urban political inquiry both intellectually and empirically.     

Race and the Production of Extreme Land Abandonment in the American Rust Belt

Extreme land abandonment is one of the most visible expressions of urban decline. Conventional theory emphasizes housing lifecycle processes, municipal fiscal challenges and deindustrialization to explain its prevalence. Empirically however, these factors are not strongly associated with the most extreme instances of land abandonment in the American Rust Belt. Race, by contrast, is strongly associated with these patterns, yet there is little mention of it in conventional theory. This article draws on group threat theory to explain how the construction of Blackness as a threat to white property, power and political influence, has propelled the production of extreme land abandonment. The constructed threat has translated into a sustained suppression of demand and capital for overwhelmingly black neighborhoods. These forces operate both independently and as an accelerant for other abandonment drivers.

City Size,Population Concentration and Productivity: Evidence from China

This paper investigates the impact of China's city size and urban population concentration on city productivity by developing a distinctive index based on global nighttime light data. Using the panel data of 280 prefecture cities from 2004 to 2013 and employing dynamic system generalized method of moments and panel threshold model regression techniques, our results show that city size has a positive impact on city productivity; therefore, cities in China still have the potential to expand. While moderate urban population concentration can benefit city productivity, excessively concentrated urban population distribution may impede the growth of city productivity. We also find that the level of labor income significantly affects the impacts of urban agglomeration on labor productivity. Therefore, our results imply that city development policies should focus more on how to appropriately allocate economic activities and adjust population distribution in urban areas according to different stages of economic development.
