Conflict on the urban fringe: Urbanization,environmental stress,and urban unrest in Africa

Most research on the security implications of environmental and demographic change does not explicitly distinguish between urban and rural areas. While statistical conflict analyses are increasingly sophisticated with respect to spatial and substantive disaggregation they largely ignore the possibility that urban and rural areas may be affected differently. In Africa, a continent assumed to be particularly vulnerable to the social and economic externalities of environmental and demographic change, less than one percent of the land mass is defined as ‘urban’. Yet, the population that lives in African cities is expected to increase by more than 150% between 2020 and 2050 according to UN population forecasts, massively outpacing rural population growth estimated at 35%. Given the vast social transformation associated with this process of rapid urbanization, understanding the dynamics and consequences of urban population growth in Sub-Saharan Africa, and its possible relationship with environmental factors is key to reducing vulnerabilities and facilitating sustainable urban growth on the continent. In this article we argue that high urban population growth may strain the provision of public services in urban areas, heighten competition over scarce urban land, and increase the chances of urban social unrest. We expect population pressure to have the most profound effects on social unrest in peri-urban areas, meaning the urban outskirts. We further investigate whether environmental push factors, operationalized as droughts happening in rural areas proximate to the urban centers, could be driving any effect of urban population growth on social disorder, possibly supporting concerns over climate change-induced social unrest. We test our expectations on a sample of similarly sized urban and peri-urban ‘grid cells’ covering the whole of the African continent for the 1997–2010 period, using geo-coded social unrest data. Our analysis shows that urban population growth is associated with increased unrest in the peri-urban areas only. We find no evidence, however, that this relationship is driven by environmental push factors in the form of nearby droughts. The study contributes insights relevant to the broader debates about possible security implications of hyper-urbanization and climate change.     

Performative citizenship and the politics of scale: Local,national and global citizenships in Zimbabwe

This paper explores the interaction between different scales of governance and performative citizenship, understood as acts by citizens that claim new political rights and reshape the political arena. Performance allows citizens to creatively transform the meanings and functions of citizenship during struggles over rights. The paper focuses on a series of examples in Zimbabwe, which highlight the entanglement of different scales of citizenship and the ways that the acts of citizenship both challenge and sustain these relationships. This is examined through a framework that combines theories of performative citizenship with concepts from human geography that examine scales of governance. The argument draws out the implications of these dynamics in relation to conflicts over customary citizenship in rural Zimbabwe, the issue of dual citizenship among white Zimbabweans and the exercise of citizenship rights by non-Zimbabweans. It highlights both the ways in which citizens have harnessed the creative potential of acts of citizenship which address multiple scales, and the constraints that scalar hierarchies put on citizen action. The examples demonstrate that new forms of political rights can be produced across scales, but that opportunities for creative acts of citizenship are unevenly distributed due to these scalar hierarchies, which are produced by postcolonial legacies.     

Geographies of Urban Politics: Pathways,Intersections, Interventions

This paper deals with urban political geographies and, most particularly, with political economy perspectives on urban politics. It offers an account that narrates what I see as influential pathways and intersections, theoretical debates, and methodological developments that have shaped contemporary urban political geographies in this vein since the 1970s, including: the ‘new urban politics’, intersections with postmodernism, and postcolonialism; urban neoliberalism and the contingency of urban politics; and, most recently, poststructural political economy and the notion of assemblage. This leads me to trace the implications of the shift in understanding from urban political geography to geographies of urban politics, and the growing emphasis on practice, contingency, relationality, and assemblage that accompany this shift. I conclude with reflections on new directions, new productive questions and tensions, and on the knowledge politics of how we do and might do contemporary urban political geographies.     

The economic structure of port cities in the mid-nineteenth century: Boston and Liverpool, 1840–1860

This paper compares the economic structures of Boston, Massachusetts, and Liverpool, Lancashire, in the mid-nineteenth century. The two cities were selected for comparative analysis because of similarities in the commodity flows through their ports, the functional status of each city in the urban hierarchies of the US and Britain and the industrial mix of each hinterland. An examination of the distribution of the labour force in each city (1850–1851) supported the assumption of functional similarity. However, in standardising the data for relative differences in the level of regional and national economic development, Boston evidenced a greater dominance over regional and national markets than did Liverpool. This was particularly true in the case of industries not directly associated with the city's port functions. The primary factor contributing to these differences was the proximity of alternative location sites in the hinterland.     

The dry tank: development and disuse of water management infrastructure in the Anuradhapura hinterland,Sri Lanka

We identify and offer new explanations of change in water management infrastructure in the semi-arid urban hinterland of Anuradhapura, Sri Lanka between ca. 400 BC and AD 1800. Field stratigraphies and micromorphological analyses demonstrate that a complex water storage infrastructure was superimposed over time on intermittently occupied and cultivated naturally wetter areas, with some attempts in drier locations. Our chronological framework, based on optically stimulated luminescence (OSL) measurement, indicates that this infrastructure commenced sometime between 400 and 200 BC, continued after Anuradhapura reached its maximum extent, and largely went into disuse between AD 1100 and 1200. While the water management infrastructure was eventually abandoned, it was succeeded by small-scale subsistence cultivation as the primary activity on the landscape. Our findings have broader resonance with current debates on the timing of introduced ‘cultural packages’ together with their social and environmental impacts, production and symbolism in construction activities, persistent stresses and high magnitude disturbances in ‘collapse’, and the notion of post ‘collapse’ landscapes associated with the management of uncertain but essential resources in semi-arid environments.     

The Rise of the “City-region” Concept and its Development Policy Implications

As well as enjoying a rich scientific history, the concept of the “city-region” has also attracted particular attention in recent years. Combinations of an urban core or cores, linked to semi-urban and rural hinterland by functional ties, are increasingly regarded as the “adequate” scale for the implementation of development policies. The popularization and widespread use of the city-region concept for policy-making has important implications for the design and implementation of development strategies. It first signals a change from sectoral to territorial approaches to development and requires the adjustment of development strategies to widely varying contexts, leading to much greater policy diversity and innovation. It also involves a more complex governance structure, characterized by the horizontal and vertical coordination of numerous institutional public and private actors, and enables experimentation with bottom-up and participatory policy-making. This paper evaluates these changes and critically addresses their normative implications, especially in light of the facts that there is still little agreement on how the city-region is defined, that the term has become appropriated by urban elites, and that the problems faced by city-regions may not be that different from those operating at other geographical scales.     

Rural population change in Nova Scotia, 1991–2001: bivariate and multivariate analysis of key drivers

Depopulation is a major demographic and economic issue in Nova Scotia, as it is in many of Canada's hinterland areas. Indian Reserves excepted, two-thirds of rural census subdivisions declined in population between 1991 and 2001, and this decline has serious economic and social consequences. By contrast, a small minority of seemingly 'rural' areas is experiencing excessive population growth through exurbanisation. This article combines map and graph analysis with simple regression and multivariate techniques to analyse the key drivers of recent population change. It is shown that such change is strongly and predictably related to unemployment rate, income and population density and moderately related to resource-industry employment, proximity to a major urban centre and commuting. These six variables are interrelated, however, and their separate contributions are explored through principal component analysis and multiple regression. Two variables—resource-industry employment and urban proximity—are identified as key root causes, indicative of separate factors. Findings are related to the Drudy–Gilg model of rural decline, and their policy implications are briefly discussed.     

铁路与沿线地区城乡经济关系的重构——以1888-1937年间的石家庄、郑州、天津为例

在1881-1937年间的华北地区,铁路运输兴起并形成网络后,其所具有的种种优势促进了新兴城市的崛起,推动了传统城市形态的演变,加快了沿海港口城市腹地的拓展.由此,这一区域内的城乡经济关系也发生了时代变动.由于以往的城乡二元结构或三元(城市、集镇、农村,或城市、城乡边缘区、乡村)结构理论关照下的笼统分析,并未反映出城乡经济关系的多样性和复杂化,因此本文将以石家庄、郑州和天津为例,试图通过考察城乡经济关系的变动与重构,揭示区域社会由传统向近代演变的特征与一般规律.     

Branded cities: outdoor advertising,urban governance,and the outdoor media landscape

Abstract: In many cities both rich and poor, new forms of outdoor advertising are emerging with potentially significant implications for the nature of the urban public realm. Public–private partnerships for advertising‐funded provision of basic items of urban infrastructure such as bus shelters, street signs and public telephones have grown as a result of structural changes in the advertising industry and shifts towards neoliberal forms of urban governance. This article critically interrogates the implications of these new outdoor advertising arrangements for the urban public realm, and argues that they have potentially harmful consequences for the accessibility and diversity of the outdoor media landscape. It then proposes three strategies for the democratisation of that landscape. These strategies are not premised on an outright rejection of outdoor advertising, but rather seek to contest the monopolistic capture of outdoor media by public–private partnerships involving urban authorities and outdoor advertising companies.     

Changing public accountability mechanisms in the governance of Dutch urban regeneration*

Contemporary urban planning dynamics are based on negotiation and contractual relations, creating fragmented planning processes. On the one hand, they trigger technocratic forms of governance, which require the ‘legal instrumentalisation’ of planning in a piecemeal approach ensuring legal certainty. On the other hand, these processes require flexibility to enable easy, fast and efficient forms of implementation due to the increasing involvement of private sector actors in urban development. This article unravels the influence of these conflicting dynamics on the fundamentals of urban planning practices by focusing on changing public accountability mechanisms created through contractual relationships between public and private sector agencies. Dutch urban regeneration has demonstrated changing governance principles and dynamics in the last three decades. Representing instrumental and institutional measures, we connect accountability mechanisms to these changes and argue that they ‘co-exist’ in multiple forms across different contexts. This article embeds this evolution in wider theoretical discussions on the changing relationships between public and private sector actors in urban governance relative to the changing role of the state, and it addresses questions on who can be held accountable, and to what extent, when public sector actors are increasingly retreating from regulatory practices while private sector actors play increasingly prominent roles.     

The Role of Government Policies and Strategies Behind the Shrinking Urban Core in an Expanding City Region: The Case of Izmir

Over the last few decades, the term urban shrinkage has come to be accepted as a valid concept in international academic circles, and has gradually gained importance, with its causes the subject of well-documented discussion. While previous discussions of urban shrinkage have directed attention to cities shrinking as a whole, recent research started to recognize the case of shrinkage in growing cities and regions. As such, recent discussions of urban shrinkage indicate that patterns of shrinkage vary considerably from city to city, and from sub-region to sub-region, with the importance of local dynamics in responding to changing economic pressures given much consideration. Recent studies have tended to disregard the role of government policies and strategies put in place to facilitate the adaptation of the urban economies to the new conditions. Taking Izmir as an example, being a fast-growing metropolitan region in Turkey, this paper presents evidence of government policies and strategies aimed at enhancing the development of peripheral areas that have led to shrinkage of the metropolitan core. This paper focuses on this experience and discusses its implications.     

Site and Community at Chunchucmil and Ancient Maya Urban Centers

Abstract

Classic Period lowland Maya urban centers often lack sharp boundaries due to progressive dispersal of residential settlement. This dispersal gives rise to questions about the concept of site and the notion of community affiliation. Research on settlement patterns at Chunchucmil, an urban center in NW Yucatan, Mexico, dating to the 5th and 6th centuries A.D., explores the issue of site boundaries and the social and economic implications of such boundaries. Detailed mapping, test pitting, and reconnaissance reveal that Chunchucmil had three densely occupied, concentric, contemporaneous zones of settlement covering between 20 and 25 sq km and inhabited by a population of up to 42,500. Data from both within and beyond the density thresholds marking the edge of the city imply the existence of communities whose boundaries do not always follow those of the site. A portion of the hinterland settlement close to the edge of the city shows stronger economic and social connections with the city, for example. These connections enable the delineation of Greater Chunchucmil, extending 5 km from Chunchucmil's center. The work at Chunchucmil also allows comparison with other large Maya cities that have been systematically documented. This comparison highlights considerable variability in Maya urban forms and in how these cities relate to their peripheries.     

Gendered,spatial and temporal approaches to Polish intra-European migration

This themed section brings together five articles focusing on distinct urban sites: Berlin/Munich, Oslo/Bergen, Belfast, Bologna and Barcelona. While there has been extensive research on Polish migrants in cities such as London, this themed issue presents a unique opportunity to explore the experiences of Polish women and men across a range of different cities. In so doing, these articles address key questions concerning implications of the specific structures and opportunities of localities where Polish migrants settle for their gendered everyday life experiences. In providing a short introduction to the themed sections, we begin by introducing some of these questions and consider the ways in which the section can contribute to on-going debates about how migrants experience and navigate place in gendered ways. We argue that gender relations and dynamics are significant to processes of migrant adaptation within particular cities. The ways in which migrants navigate their new locations are shaped not only by institutional structures but also by gendered, classed and racialised power dynamics enacted in and through those spaces. By examining the experiences of Polish migrants across various city spaces in different national contexts, we consider how migrants may adopt particular strategies to negotiate these specific ‘spaces of encounter’.     

The Archaeology of Tula, Hidalgo, Mexico

The site of Tula, Hidalgo, Mexico, is well known for its distinctive architecture and sculpture that came to light in excavations initiated some 70 years ago. Less well known is the extensive corpus of archaeological research conducted over the past several decades, revealing a city that at its height covered an area of c. 16 km² and incorporated a remarkably diverse landscape of hills, plains, alluvial valleys, and marsh. Its dense, urban character is evident in excavations at over 22 localities that uncovered complex arrangements of residential compounds whose nondurable architecture left relatively few surface traces. Evidence of craft production includes lithic and ceramic production loci in specific sectors of the ancient city. Tula possessed a large and densely settled hinterland that apparently encompassed the surrounding region, including most of the Basin of Mexico, and its area of direct influence appears to have extended to the north as far as San Luís Potosí. Tula is believed to have originated as the center of a regional state that consolidated various Coyotlatelco polities and probably remnants of a previous Teotihuacan-controlled settlement system. Its pre-Aztec history exhibits notable continuity in settlement, ceramics, and monumental art and architecture. The nature of the subsequent Aztec occupation supports ethnohistorical and other archaeological evidence that Tula’s ruins were what the Aztecs called Tollan.     

Statecraft,Scalecraft and Urban Planning: A Comparative Study of Birmingham,UK, and Brisbane,Australia

Recent discussions on state rescaling have pointed towards the need for a greater focus on how and why state activity may change over time in order to generate insights into the provenance, trajectories and outcomes of rescaling in different global regions and national state spaces. Consequently, this paper explores the dialectical and recursive relationship between the concepts of “statecraft” and “scalecraft” to explore the evolving sites, objects and mechanisms for urban planning within two key urban centres in different parts of the world—Birmingham, UK, and Brisbane, Australia. It is illustrated how a range of actors—from the national to the local level—have sought to craft and reshape the strategies and structures for urban planning according to different imperatives. In turn, the implications for a tighter specifying of the process of state rescaling are considered, as well as the subsequent nature of urban planning arrangements.     

Large Projects in Hinterland Regions: A Dynamic Multiregional Input-Output Model for Assessing the Economic Impacts

Interregional spillovers and the expansion of capacity in hinterland sectors represent two types of economic impact associated with large capital projects in hinterland regions. The simultaneous treatment of these within an input-output (I-O) framework is the subject of this paper. A dynamic multiregional I-O (DMRIO) model is derived and applied to a scenario of oil development in Canada's Northwest Territories (NWT). A comparision of output profiles generated by the DMRIO model and a static MRIO model shows that the DMRIO formulation has merit. Specifically, in years where capacity adjustments are called for in the hinterland region, the static MRIO model is unable to capture the intraregional and interregional economic implications of this activity. In a year of particularly large-capacity shortfalls in several NWT sectors a static MRIO model underestimates the Canada-wide total impact of the project by more than one billion 1984 dollars.     

Individual Accessibility Revisited: Implications for Geographical Analysis in the Twenty‐first Century

Analytical methods for evaluating accessibility have been based on a spatial logic through which the impedance of distance shapes mobility and urban form through processes of locational and travel decision making. These methods are not suitable for understanding individual experiences because of recent changes in the processes underlying contemporary urbanism and the increasing importance of information and communications technologies (ICTs) in people's daily lives. In this paper we argue that analysis of individual accessibility can no longer ignore the complexities and opportunities brought forth by these changes. Further, we argue that the effect of distance on the spatial structure of contemporary cities and human spatial behavior has become much more complicated than what has been conceived in conventional urban models and concepts of accessibility. We suggest that the methods and measures formulated around the mid‐twentieth century are becoming increasingly inadequate for grappling with the complex relationships among urban form, mobility, and individual accessibility. We consider some new possibilities for modeling individual accessibility and their implications for geographical analysis in the twenty‐first century.     

Indigenous health organizations,Indigenous community resurgence,and the reclamation of place in urban areas

Research around the world has been nearly unanimous about the positive impacts of Indigenous‐led health organizations on Indigenous peoples' qualitative experiences in health care, in the face of often negative experiences in non‐Indigenous‐led health care settings. Urban environments, including health care environments, are areas of increasing attention with regard to Indigenous peoples' health in Canada. In this study, which took place in the northern city of Prince George, British Columbia, 65 Indigenous community members and health services workers participated in interviews and focus groups, describing their experiences with urban Indigenous‐led health organizations—defined in this study as non‐governmental organizations that prioritize the values and practices of local Indigenous communities. Employing perspectives on place and relationships drawn from Indigenous critical theory and Indigenous community resurgence to analyze the findings of this qualitative study leads to a focus on how relationships impact and can even constitute places, enabling new understandings of the roles of Indigenous‐led health organizations in urban Indigenous community resurgence.     

Women,Wages and Intra-household Power Relations in Urban Bangladesh

This article examines the implications of women's access to income-earning opportunities for their position in intra-household relationships. For those who believe that such relationships are egalitarian, this issue may not appear relevant; for others, however, there is a divergence of views between those who offer an optimistic analysis of the effects of earning power for women's status, and those who provide a more pessimistic prognosis. In exploring this issue, the article makes use of first-hand accounts of women workers in the recently emergent export-oriented garment factories in Bangladesh, both in order to evaluate the ‘fit’ with theoretical insights of intra-household relations from the social science literature, and to assess what the ‘everyday lived realities’ described by the women workers tell us about the workings of power within family-based households in urban Bangladesh.
