Negotiating Green Space with Landed Interests: The Urban Political Ecology of Greenway in the Pearl River Delta,China

Land‐centred urbanisation has precipitated shortage of green space in Chinese cities. However, in the Pearl River Delta, an ambitious greenway system has recently managed to flourish. It is intriguing to ask how this has become possible. Informed by the perspective of urban political ecology, this paper finds that the greenway project in the Pearl River Delta represents a set of politically realistic endeavours to alleviate urban green space shortage by adapting to, rather than challenging, powerful landed interests. Three interlocking dimensions about land—municipal land quota, rural land use claims, and real estate development—have influenced why, where and how greenways have been created. Based on these findings, we argue that research on China's politics of urban sustainability necessarily needs to understand the country's land politics.     

Spatial distribution of US employment in an urban efficiency wage setting

We analyze whether efficiency wages operate in urban labor markets, within the framework proposed by Ross and Zenou, in which shirking at work and leisure are assumed to be substitutes. We use unique data from the American Time Use Survey (ATUS) that allow us to analyze the relationships between leisure, shirking, commuting, employment, and earnings. We confirm that shirking and leisure are substitutes, and present an estimate of this relationship, representing the only empirical test of the relationship between a worker's time endowment and shirking at work. Our findings point to the existence of efficiency wages in labor markets.     

Local employment growth patterns and the Great Recession: The case of Spain

The 2008 financial and economic crisis has led to widespread destruction of employment in Spain. Using municipality data, I examine employment growth differences between urban cores, urban hinterlands, and rural areas during the pre‐crisis period and the recession period. The data show that patterns of growth and decline have been very uneven across different types of areas. While in the boom years, hinterlands and rural areas experienced higher growth, urban core areas have done better during the recession years. I then test three strands of explanations for local growth differences: (i) the role of the local sectoral composition, (ii) the role of human capital, and (iii) the role of access to urban core areas. Estimations for employment growth in the two periods show that the crisis has altered some of the drivers of local employment growth and that human capital has been a key determinant of local resilience during the Great Recession.     

Fixing a Swamp of Cobras: The Clash between Capital and Water in Shaping Urban Vulnerabilities

This paper addresses how capital can refashion landscapes and patterns of risk and vulnerability. Drawing on the emblematic case of the conversion of Thailand’s Cobra Swamp into Suvarnabhumi International Airport we argue that there is a fundamental clash between the internal logic of capital accumulation and the ecology of water that occurs in places in which land is under water for much of the year. Counterintuitively investment in public infrastructure such as airports targets locations that are exposed to flood risks. While the literature on capital fixes tends to treat “land” writ large, this paper adds a dimension that has been overlooked in the theoretical work, by highlighting the significance of the ecology of the land in which such fixes occur as a means of understanding patterns of investment, land use change and vulnerability. Our analysis draws on three separate but related concepts of capital “fixes”—spatial, technological and high/low road fixes. We argue the importance of recognising the specific ecological characteristics of land that capital “fixes”. This perspective has global significance in providing critical insight into the ways in which capital creates and accommodates the kinds of vulnerabilities and risks associated with climate change.     

Population,light, and the size distribution of cities

We provide new insights on the city size distribution of countries around the world. Using more than 10,000 cities delineated via geospatial data and a globally consistent city identification scheme, we investigate distributional shapes in all countries. In terms of population, we find that Zipf's law holds for many, but not all, countries. Contrasting the distribution of population with the distribution of economic activity, measured by nighttime lights, across cities we shed light on the globally variant magnitude of agglomeration economies. Deviations from Zipf's law are to a large extent driven by an undue concentration in the largest cities. They benefit from agglomeration effects which seem to work through area rather than through density. Examining the cross‐country heterogeneity in the city size distribution, our model selection approach suggests that historical factors play an important role, in line with the time of development hypothesis.     

Locational disadvantage and the spatial distribution of government expenditure on urban infrastructure and services in metropolitan Sydney (1988–2015)

Provision of public services by state governments rather than municipalities is considered an important urban governance factor preventing deeper levels of socio‐spatial inequality in Australian cities. The paper examines the spatial patterns of investment by the New South Wales state government in a wide range of services and infrastructure in metropolitan Sydney over 28 budget years from 1988/89 to 2015/16. We examined the relationship between volume and type of investment in infrastructure and services, and considered a local area's socioeconomic characteristics, distance from the central business district, and designation as a strategic site in metropolitan plans. Despite an overall redistributive approach favouring relatively disadvantaged areas, the most disadvantaged suburbs in metropolitan Sydney had significantly lower levels of investment. When funding was directed to the most disadvantaged suburbs, it was often in the form of new social housing development, reinforcing both the concentration of poverty and disadvantage in resource access. The findings suggest that this is a case of under‐investment by the state government in areas already populated by disadvantaged communities rather than a market‐driven process whereby disadvantaged households move into poorly resourced neighbourhoods.     

Tracing resident antagonisms in urban development: agonistic pluralism and participatory planning

This article draws on research with resident action groups and other alliances in Sydney. It investigates the ways in which citizens work beyond the formal planning system to approach and achieve their urban development goals. The post‐political treatment of community voices in planning relies on the centrality of consensus politics in current participatory planning regimes. By providing a democratic outlet that is far removed from the actual development outcome, powerful urban actors can silence through inclusion. Planning theorists have posited that one pathway beyond this post‐political moment in urban planning is provided by Chantal Mouffe's critique of Habermasian communicative theory and consensus politics, which she bases on her theory of agonistic pluralism. Following Mouffe, to achieve a productive agonistic politics, any rigid antagonisms between “enemies” need to be moderated to more mutable “adversarial” positions. However, we have little knowledge of the conditions that might precipitate such a change in praxis. To address this gap between theory and praxis, we use focus group data to show how local resident action groups and urban alliances work through three modalities of antagonism to achieve their urban development goals. We add empirical weight to the idea that citizens can shift from rigid and fundamental antagonisms to the potentially more productive adversarial politics of agonistic pluralism but therein expose some limitations with how Mouffe's ideas are being applied to urban planning.     

The lit world: living with everyday urban automation

In this article, we develop and advance the concept of the lit world by bringing together literatures about everyday lighting, automation in everyday life and human perception, along with our ethnographic research into people’s experience of automated lighting in Melbourne, Australia. In doing so we formulate and argue for an approach to automation that situates it as part of everyday mundane worlds and acknowledges its entanglement with the emergent and experiential qualities of everyday environments as they unfold. We demonstrate this through the example of automated lighting, understood as a situated technology that has contingent effects and participates in the making of particular ways of seeing and feeling the world. We thereby argue for an account of automation that reaches beyond its potential for the management of human (and other) behaviour, to ask how the qualities and affordances of automated technologies might seep out of their intended domains, and create new perceptual and experiential opportunities. In a context where automation is increasingly prevalent in everyday life, such attention to the experience and use of automated technologies which already exist on a large scale is needed. Urban lighting is an example par excellence of automation in the world because it has a long history beyond the recent association of automated technologies with code and digital infrastructures. As scholars debate how automated technologies will become part of our future digital lives, understanding how people live in a lit world offers a starting point for considering how we might live with other anticipated algorithmic forms of automation.     

New World civitas,contested jurisdictions,and inter-cultural conversation in the construction of the Spanish Monarchy

Jurisdictional frontiers were created, contested, and negotiated among a wide range of actors, including native Americans and Europeans, with reference to the cities founded in Castilla del Oro (roughly present-day Panama). This research deals, first, with the reshaping of the concept of a city in the New World, based on its inhabitants’ sense of civitas. It analyses, secondly, the creation and redefinition of jurisdiction during political conflicts and, third, the construction and maintenance of jurisdiction through local relations with indigenous populations described as ‘conversation’. The analysis of the creation and preservation of local jurisdictions allows for an interpretation of the complexities involved in the configuration of political power and political space from below in the territories claimed by the Spanish Monarchy.     

Comparing expeditious procedures for the seismic vulnerability assessment on the European territorial context: reliability,feasibility, cost,and time consumption

ABSTRACT

The definition of strategies for the preservation and protection of cultural heritage is a topical issue, especially in view of the increasing relevance of the theme of seismic risk mitigation and reduction.

The prediction of the impact an earthquake could have on existing buildings requires the knowledge of their dynamic behaviour. The procedure to be adopted for this purpose is quite complex and onerous in terms of costs, time, and implementation, especially when the study concerns territorial areas rather than single buildings. The definition of methodologies aimed at respecting the principles of economic sustainability and preserving human life and architectural heritage is of paramount importance to assess seismic vulnerability using available resources. Rapid methods for the seismic vulnerability assessment, aimed at defining buildings vulnerability and intervention priority lists, must be implemented to guarantee the preservation of historical centers.

This article describes the application to some case studies of different methods aimed at creating fragility curves for the vulnerability assessment on the European territorial context. The comparison between a deterministic approach and a new probabilistic one is performed for all case studies, to define the most suitable methodology in terms of reliability and savings in cost and time.
