A growing number of cities in the global South are taking proactive action on climate change. Their plans provide insights into the potential for strategically bundling long‐term development policymaking with the climate agenda. In this article I study the case of Delhi, the first city in India to adopt a climate change action plan. Drawing on the literature on urban ecological security, I examine: (1) the adaptation challenges that Delhi faces; (2) the multiple motivations that underlie early action; (3) the key actors, strategies, and associated action domains outlined in the plan; and (4) the extent to which the plan seeks to bring about systemic change. Proactive action at the city level serves multiple strategic goals. Delhi's case is significant in illustrating how it has leveraged emergent opportunities to advance its short‐term development agenda, given the tight fiscal constraints and governance challenges it faces. The plan has been strategically formulated to enhance competiveness, facilitate image‐building, garner support for pet projects and access alternative sources of funding. But the short‐term orientation of the plan and its limited mechanisms for citizen engagement have severely restrained its capacity to address underlying social vulnerabilities or bring about transformative change.  相似文献

Cities are key drivers of global climate change, with the majority of greenhouse gas (GHG) emissions being tied to urban life. Local actions to mitigate and adapt to climate change are essential for stabilization of the global climate and can also help to address other urban ecological problems such as pollution, decreasing biodiversity, etc. Companies are important urban actors in the development of low‐carbon cities because they provide a multitude of goods and services to city populations and directly influence urban carbon dioxide (CO2) emissions. This is a new area of research. While studies on corporate sustainability are numerous, there is little, if any, existing research that examines the role of companies in climate change adaptation and mitigation within specific urban areas. Urban ecologists also have not examined how corporate activity affects urban systems. Taking a multi‐disciplinary systems approach, we present a conceptual model of the role of companies in managing urban interactions with the climate system. We also present empirical findings illustrating how one company ‘partners’ with the city of Rotterdam to test electric vehicles as a pilot project for urban climate adaptation and mitigation.

Shrinking cities: urban challenges of globalization   总被引:6,自引:0,他引:6  
Urban shrinkage is not a new phenomenon. It has been documented in a large literature analyzing the social and economic issues that have led to population flight, resulting, in the worse cases, in the eventual abandonment of blocks of housing and neighbourhoods. Analysis of urban shrinkage should take into account the new realization that this phenomenon is now global and multidimensional — but also little understood in all its manifestations. Thus, as the world's population increasingly becomes urban, orthodox views of urban decline need redefinition. The symposium includes articles from 10 urban analysts working on 30 cities around the globe. These analysts belong to the Shrinking Cities International Research Network (SCIRN), whose collaborative work aims to understand different types of city shrinkage and the role that different approaches, policies and strategies have played in the regeneration of these cities. In this way the symposium will inform both a rich diversity of analytical perspectives and country-based studies of the challenges faced by shrinking cities. It will also disseminate SCIRN's research results from the last 3 years.  相似文献

The aim of this symposium is to examine the situation of the creative economy in cities—specifically cities of sub-Saharan Africa. In this introduction we set out the case for the need to ‘re-describe’ the (much derided) phenomenon of the creative city. This task requires clarification of what is understood in academe and policy communities by the term ‘creative economy’, the pronounced growth of this sector, particularly in the global South, and its particular urban character. Secondly, in the face of conceptual and policy confusion we argue for the actually existing, and growing, importance of the urban creative economy. Thirdly, with this ground clearing achieved, we seek to frame, and focus on, the emergence of new research on the urban creative economy. Finally, we use the evidence from the symposium contributions to argue for a reformulation of the creative economy within African sub-Saharan urbanization.  相似文献

The article discusses an instance of knowledge that failed to circulate — the application of urban climatology in town planning. This field of applied science was systematized in German‐speaking universities and cities and remains most firmly established in North‐Central Europe. In the decades after the second world war successive commissions and study groups of the World Meteorological Organization, the International Federation of Housing and Planning, the Confédération Internationale du Bâtiment and the International Society for Biometeorology sought to spread awareness of climatological factors among planners and architects worldwide. The article examines the organizations and individuals involved in this campaign, describes their meetings, publications and outreach, and assesses the disappointing impact. The legacy of this failure is considered in the context of present‐day interest in planning for carbon mitigation and climate‐change adaptation.  相似文献

The world’s urban population is expected to grow fifty percent by the year 2050 and exceed six billion. The major challenges confronting cities, such as sustainability, safety, and equality, will depend on the infrastructure developed to accommodate the increase. Urban planners have long debated the consequences of vertical expansion—the concentration of residents by constructing tall buildings—over horizontal expansion—the dispersal of residents by extending urban boundaries. Yet relatively little work has predicted the vertical expansion of cities and quantified the likelihood and therefore urgency of these consequences.We regard tall buildings as random exceedances over a threshold and use extreme value theory to forecast the skyscrapers that will dominate the urban skyline in 2050 if present trends continue. We predict forty-one thousand skyscrapers will surpass 150 meters and 40 floors, an increase of eight percent a year, far outpacing the expected urban population growth of two percent a year. The typical tall skyscraper will not be noticeably taller, and the tallest will likely exceed one thousand meters but not one mile. If a mile-high skyscraper is constructed, it will hold fewer occupants than many of the mile-highs currently designed. We predict roughly three-quarters the number of floors of the Mile-High Tower, two-thirds of Next Tokyo’s Sky Mile Tower, and half the floors of Frank Lloyd Wright’s The Illinois—three prominent plans for a mile-high skyscraper. However, the relationship between floor and height will vary considerably across cities.  相似文献

This symposium creates and stimulates new dialogue and cross‐disciplinary exchange between planning theorists and geographers in researching the transfer of urban policy and planning models, ideas and techniques. The symposium challenges a restricted historical focus in much of the emerging geographical literature on urban policy mobilities by drawing on a rich tradition within planning history of exploring and documenting the trans‐urban travel of planning ideas and models over the last 150 years. It is argued that this longer‐term perspective is required to highlight important historical continuities and institutional legacies to contemporary urban policy circuits and pathways and to question what is particularly new, distinct and innovative about an intensification in the travel of urban ideas, plans and policies over the past decade — and the accompanying scholarly interest in them. The symposium also uses the emphasis on particular details and specific experiences within planning histories to foreground and develop approaches, particularly from recent geographical scholarship, that investigate the contingent and embodied practices and wider epistemic contexts that enable — or hinder — contemporary policy transfer.  相似文献

Climate change presents multiple challenges to citiesnot only in terms of the resilience and sustainability of the urban fabric, but also in relation to how urban inhabitants imagine they might adapt to a future transformed environment. This article explores imaginative modes of thinking in relation to future cities and climate change, focusing on representations of urban drowning or submergence. It considers, in turn, climate‐change fictionsfrom J.G. Ballard's 1962 novel The Drowned World to Paulo Bacigalupi's The Drowned Cities, published in 2012; visual representations from Gustave Doré's The New Zealander in 1872 to Alexis Rockman's 2004 Manifest Destiny; and architectural conjecture, from Wolf Hilbertz's Autopia Ampere project from 1970 onwards to CRAB Studio's Soak City in 2009. The article draws out how these imaginaries intersect with theoretical understandings of science fiction and ecology, contending that an emphasis on multiple imaginaries of climate change is critical to expanding the narrow range of possibilities that currently characterize the literature on cities and climate change. Imaginative texts, images and designs mutually inform each other to encourage holistic ways of approaching how we think about the prospect of urban submergence and to incubate radical responses to it.  相似文献

How should we understand the recent rapid spread of eco-urbanism around the world and its move into the mainstream? This understanding has become increasingly dominated by narratives of the urban sustainability fix, which stresses the logic of capital accumulation. Within the broader structural processes of ecological modernization, such as transitioning to low-carbon growth, consideration of—let alone interest in—the diversity of local politics that shapes the practice and forms of contestation of eco-urbanism has often been relegated to a position of secondary importance. Meanwhile, investigations of the relationship between the growth of climate governance and grassroots environmental activism often ignore space production as an underlying process of political-economic transformation. Drawing on a detailed case study of the prevalence of zero-waste neighborhood experiments in many Chinese cities, which have recently become obsessed with low-carbon growth, this article underscores the potential of grassroots activism to change the nature, dynamics and landscape of eco-urbanism significantly. On the basis of the intriguing evidence presented here, it calls for a new understanding of eco-urbanism: one which is more attentive to the diversity, heterogeneity and contextual sensitivity of urban change at the grassroots level.  相似文献

The shrinking mining city: urban dynamics and contested territory   总被引:4,自引:0,他引:4  
Shrinking mining cities — once prosperous settlements servicing a mining site or a system of mining sites — are characterized by long-term population and/or economic decline. Many of these towns experience periods of growth and shrinkage, mirroring the ebbs and flows of international mineral markets which determine the fortunes of the dominant mining corporation upon which each of these towns heavily depends. This dependence on one main industry produces a parallel development in the fluctuations of both workforce and population. Thus, the strategies of the main company in these towns can, to a great extent, determine future developments and have a great impact on urban management plans. Climate conditions, knowledge, education and health services, as well as transportation links, are important factors that have impacted on lifestyles in mining cities, but it is the parallel development with the private sector operators (often a single corporation) that constitutes the distinctive feature of these cities and that ultimately defines their shrinkage. This article discusses shrinking mining cities in capitalist economies, the factors underpinning their development, and some of the planning and community challenges faced by these cities in Australia, Canada, Japan and Mexico.  相似文献

We outline the rationale for reopening the issue of the spatiality of the ‘urban’ in urban politics. There is a long tradition of arguing about the distinctive political qualities of urban sites, practices and processes. Recent work often relies on spatial concepts or metaphors that anchor various political phenomena to cities while simultaneously putting the specificity of the urban itself in question. This symposium seeks to extend debates about the relationship between the urban and the political. Instead of asking ‘what is urban politics?’, seeking a definition of the urban as a starting point we begin by asking ‘where is urban politics?’. This question orients all of the contributions to this symposium, and it allows each to trace diverse political dimensions of urban life and living beyond the confines of ‘the city’ as classically conceived. The symposium engages with ‘the urban question’ through diverse settings and objects, including infrastructures, in‐between spaces, professional cultures, transnational and postcolonial spaces and spaces of sovereignty. Contributions draw on a range of intellectual perspectives, including geography, urban studies, political science and political theory, anthropology, cultural studies, sociology, planning and environmental studies — indicating the range of intellectual traditions that can and do inform the investigation of the urban/political nexus.  相似文献

This article explores the use of contingent forms of employment in two diverse country contexts—the UK and Sweden—and investigates the influence of changing regulatory and economic conditions over a period that covers the current economic downturn. Drawing on quantitative and qualitative data for the construction sector, the article addresses three questions. How do employers balance their flexibility preferences in the context of regulatory constraints? How has the global recession influenced employer behaviour? And to what extent can the Swedish experience be explained by convergence on other country models? While the UK employment model encourages employers to externalise the risk of unpredictable market conditions through the use of contingent contracts, the more supportive welfare regime in Sweden underpins a resilient preference of employers for open‐ended employment contracts. Ongoing changes in labour market regulation pose challenges to the strongly regulated Swedish model, yet we find only a shared direction of travel with the UK rather than convergence in the use of contingent employment.  相似文献

The current era of global urbanization is defined by a convergence of economic and political crises requiring urgent sociological reflection on the meaning of the ‘urban' today. This article responds to the current rethinking of worldwide processes of urbanization sparked off by Brenner, and Brenner and Schmid, arguing for a renewed sociological approach to urban formations that probes beyond the economic logic of urban ‘de‐territorialization', towards the capricious life‐worlds and forms of planetary organization that define the urban. We pursue a theory of the ‘urban vortex' to capture the maelstrom of disorienting crises since 2008, and explicate the social formations implicated in the construction, materialization and practice of power and transgression in cities today. Our aim is to consider what forms of social change emerge in volatile, intense and centralized dynamics (the urban vortex), and how this might relate to arrangements of interconnectivity, particularity and variegation (the planetary). The article highlights three prominent processes of urban social formation: accumulation, stratification and hyper‐diversity—reinstating the need to theorize the centrality of the city within the formations of twenty‐first century capitalism.  相似文献

Automobility — the centering of society and everyday life around automobiles and their spaces — is one of the most contentious aspects of contemporary urban growth debates at the local, national, and global scale. The politics of automobility is a spatial struggle over how the city should be organized and for whom. Yet there is little research on how this struggle is unfolding, and how that politics is shaping urban space. Part of this stems from the essentialization of automobility in policy and academic discourses on cities. Moving beyond essentialization, this article will explore how contentious political struggles reveal nuanced and diverse discourses and ideologies surrounding automobility and space. Focusing on what I call ‘secessionist automobility’— using an automobile as an instrument of spatial secession — I examine Atlanta, Georgia’s contentious automobility debate. Secessionist automobility is bound with the blunt politics of race‐based secession from urban space, but also more subtle forms of spatial secession rooted in anti‐urban ideologies. Implications for local, national, and global contestation of automobility will be provided.  相似文献

Advancing global urbanism depends upon making Africa's cities a more dominant part of the global urban narrative. Constructing a more legitimate research agenda for African cities, however, necessitates a repositioning of conventional modes of research. To achieve intellectual and political traction in what are typical African research conditions—where human needs are great, information is poor, conditions of governance are complex and the reality is changeable—we reflect on the experiences of the African Centre for Cities where (alongside conventional use of theory, methods and data) a translational mode of working has been adopted. The notion of translational urban research praxis captures more than the idea of applied research or even co‐production, and encompasses integrating the research conception, design, execution, application and reflection—and conceiving of this set of activities as a singular research/practice process that is by its nature deeply political and locationally embedded. In this way we suggest that African urbanism can be both usefully illuminated by global theories and methods, and can simultaneously be constitutive of the reform of the ideas through which cities generally are understood.  相似文献

According to Richard Florida, the world is in the grip of a ‘New Urban Crisis’. In his most recent book Florida recounts a visit to Medellín that provoked an epiphany in which he realized that the New Urban Crisis is global in scope. Unfortunately, Florida's discovery of the global South is informed by a deeply Eurocentric understanding of urbanization. This leads him to conclude that Southern cities should ‘unleash’ creativity, and he proposes that the United States should develop a global urban policy that would export a version of American urbanism. In this essay we deconstruct Florida's notion of the New Urban Crisis and show that its Eurocentric assumptions obscure the very real environmental, economic and political challenges facing cities in the global South and their residents.  相似文献
