The cry and demand for the Right to the City (RttC) risks becoming a cliché, merely signifying urban rebellion rather than proving its practical content on the ground. I explore the limits of the thesis via its fraught entanglement with private property rights and the state‐form; and through Lefebvre's radical critique of the state, political economy and rights elsewhere. Rights claims, I contend, unintentionally reify the uneven power relations they aim to overcome, while routinely cauterising the hard‐fought collective social force that forces social gains. As a counter to the RttC thesis, I explore the autonomous Take over the City (TotC) movements of 1970s Italy, arguing that these largely neglected eminently immanent forms of territorial community activism, brought here into dialogue with Lefebvre's conception of territorial autogestion, surpassed the RttC thesis in praxis. The experience of “Laboratory Italy” thus provides highly suggestive lessons for a contemporary politics of urban space.  相似文献

This paper discusses degrees of urbanity or urbanities using ethnographic data from research conducted among the Grecanici communities in the city of Reggio Calabria, south Italy. Urbanization in south Italy is usually associated with social and territorial mobility, education and natural disasters. It is further discussed in terms of a rural/urban duality that masks rather than reveals possible diversities concerning the social life in the city and the links between rural and urban which in the urban environment follow different trajectories. Following the premise that the effects of urbanization cannot be homogenously felt by the actors, I follow the Grecanici migration to the city of Reggio Calabria in the decade of the 1950s in order to argue that urbanities are directly informed by factors such as kinship, neighbourhood identification, education and socio‐economic status.  相似文献

The major environmental problems of the twenty‐first century, including climate change, water scarcity, pollution and resource exhaustion, represent a new category of crisis and highlight the desperate need for an integrated science of socio‐ecological phenomena. To help establish the foundations of such a science, we explore three traditions of mathematical theory: the Lotka–Volterra interactions of ecological theory, niche construction models of population genetics, and theory from the gene–culture coevolution tradition. We review the theoretical tools of each of these traditions in explaining cultural articulation with the environment. Although the theoretical core of the science we propose does not exist, cultural evolutionary theory supplies useful tools to analyse endogenous culture, cultural dynamics, and deeply rooted behavioural links to the environment. We also present a coupled model for demonstration, and suggest that coupled socio‐ecological models can provide a formal theory to help address the emergent socio‐ecological problems of the future.  相似文献

Happiness data are rarely used in regional and urban analysis, but it is a prime data set for testing the assumption of spatial equilibrium, the key assumption in the field of urban economics. In this paper, we explore the relationship between regional happiness and one‐year lagged change in population growth rates for the nine census regions in the United States using data on reported well‐being from National Opinion Research Center's annual General Social Survey. We observe that, while there is evidence of spatial disequilibrium during recessions and in the long run, happier regions generally experience higher population growth rates indicating a movement (or tendency) toward spatial equilibrium.  相似文献

Although territorial disparities in land quality are commonly observed in Mediterranean‐type ecosystems, how different geographical gradients impact the changing distribution of land vulnerable to degradation over time and space is poorly investigated in southern Europe. The present study assesses the spatial distribution of vulnerable land according to a composite index that describes the degree of land vulnerability to degradation in Italy along eight gradients during two time periods (1960–1990 and 1990–2010), representing distinct socio‐economic and environmental conditions. While the degree of land vulnerability increased at similar paces from 1960 to 1990 and from 1990 to 2010, the spatial distribution of vulnerable land changed considerably. From 1960 to 1990, the area of vulnerable lands increased in coastal areas, lowlands, and areas with moderately high population density, mainly owing to the increased climate aridity. By contrast, peri‐urban areas experienced, especially in northern Italy, the highest vulnerability from 1990 to 2010 owing to increased human pressure on land generating, e.g. land‐use changes. Results indicate that the importance of the gradients shaping the distribution of vulnerable land in Italy is reflected in the (changing) role of climate, vegetation cover, and human pressure as factors predisposing land to degradation. Finally, policy implications of the changing geography of vulnerable land in the Mediterranean region are discussed.  相似文献

We analyse a half‐century of Chilean urban reforms to explain the introduction of a system of urban accumulation by dispossession of public resources and opportunities. Three stages have been conceptualised in the imposition of a neoliberal creative‐destructive process: proto‐neoliberalism, roll‐back and roll‐out periods. Empirical studies have traditionally analysed this process by examining a single urban policy's evolution over time. In this paper, we go beyond these types of studies by performing a systemic analysis of multiple urban policy reforms in Santiago, Chile. We use a genealogical thematic analysis to track changes in laws, government programmes and planning documents from between 1952 and 2014. Our analysis identifies different “urban systems of accumulation” by looking at the interplay of four urban policies: (1) urban planning deregulation; (2) social housing privatisation; (3) devolution of territorial taxes; and (4) decreased public service provision. Moreover, our multidimensional policy analysis in Santiago characterises a more radical, fourth expression in the creative destruction process of “accumulation by dismantling”. Consequently, we advocate for more multidimensional urban policy research that goes beyond a three‐period analysis in order to gain a deeper understanding of contemporary neoliberal creative‐destructive processes in variegated geographies.  相似文献

This article explores the role of two large European rivers — the Rhine and the Danube — in the structured development of the European territorial system. The water resources of the Rhine river, the tributaries and connecting canals have created the greatest industrial megalopolis on the continent. In this process and under contemporary conditions, the area is connected with the Danube basin by the newly built Rhine‐Main‐Danube canal. As a result, new structures are forming, having the character of an ecological‐economic system. It is in this direction that part of the European territorial system connected with the Danube is developing. As physical‐geographical and ecological factors accelerate economic development and integrate new economic structures, new opportunities arise. With the link to ecological and water resources, development of the Danube as Europe's newest, prospective zone of expansion is predicted.  相似文献

There have been significant territorial changes in the Spanish Mediterranean in the last few decades because of the important growth of residential tourism functions. The Spanish National Hydrological Plan ( 2001 ) and, to a greater extent, the Action for Management and Use of Water Programme ( 2004 ) advocated large‐scale desalination of seawater to guarantee a supply for urban, tourism, and even future agricultural demands. The paralysis of urban development planning caused by the financial crisis (2007/08), together with the downward trend in the consumption of drinking water in the last decade, highlighted a capacity to produce desalinated water that was far superior to actual needs. This study reviews the current context in which desalinated water is produced in Spain, weighs up the advantages and disadvantages of this method of water management, and considers the potential role that this non‐conventional source of water could play as a strategic resource in the future. The main findings of the study are that desalination is not a panacea; rather, it should be considered in terms of technological parameters tailored to the circumstances of each geographical and socioeconomic environment.  相似文献

This study illustrates an exploratory approach based on a Multiway Factor Analysis (MFA) to estimate rapidity of change in complex urban systems, based on “fast” and “slow” variables. The proposed methodology was applied to 18 socioeconomic indicators of long‐term (1960–2010) transformations in 115 municipalities of Athens’ metropolitan area (Greece), including demography, land‐use/planning, and urban form and functions. Athens was regarded as a dynamic urban area with diversified structures and functions at the local scale, expanding through a self‐organized pattern rather than a centralized planning strategy. Athens’ urban system was described using nine supplementary (topographic and territorial) variables and 30 independent indicators assessing the local context in recent times. Exploratory data analysis found an increasing connectedness and redundancy among socioeconomic indicators during the phase of largest urban expansion (1960–1990). Only the rate of population growth was classified as a “fast” variable for all five decades investigated. The overall rapidity of change was higher in 1960–1970, 1980–1990, and 2000–2010, decades that coincided with specific phases of urban expansion driven by migration inflow, second‐home suburbanization, and Olympic games, respectively. Rapidity of change was high for functional indicators during all five decades studied, while demography indicators changed more rapidly in the first three decades and land‐use/planning indicators in the last two decades. Rapidity of change was highest in peri‐urban municipalities with a highly diversified economic structure dominated by industry. Our methodology provides a comprehensive overview of the transformations of a complex urban system, quantifying low‐level indicators that are rarely assessed in the mainstream literature on urban studies. These results may contribute to design policies addressing complexity and promoting resilience in expanding metropolitan areas.  相似文献

This paper aims to discuss institutional capacity building in spatial planning focussing on two experiences of public policy in Portugal involving institutional cooperation. These experiences reveal the importance of factors associated with the roles of the central state and local political leadership in the way integrated tools of urban and territorial policy are implemented. They also show that the capacity to mobilize local agents is mitigated by the deep-rooted presence of highly personalized institutional ties, reflecting a relational model that is particularly characteristic of Portuguese society. We will conclude that territorial policies may be jeopardized when these policies are centred mainly upon the mobilization of local agents. In fact, these two case-studies, as well as similar experiences in Italy, suggest that, in southern Europe, two other aspects are central for the definition of territorial policies on the inter-municipal and local scales: the influence of the state, and the role of political leadership at local level.  相似文献

This paper explores how territorial economic governance is discursively constituted in a globalising and neoliberalising world. It acknowledges both the increasingly recognised formative role of spatial imaginaries in economic interventions and the workings of co‐constitutive political projects that link particular imaginaries with political ambitions and policy strategies. Embracing recent calls for comparative ethnographic urban research at the local‐global interface, it explores currently dominant spatial imaginaries across the four Australasian cities of Auckland, Sydney, Melbourne, and Perth. Based on multiple qualitative methods, this study claims that a considerable number of actor's spatial associations and reference points can be related to particular city‐specific governmental projects; Auckland's Super‐City, Sydney's Global and Green City, Melbourne's Liveable City, and Perth's Vibrant City. It is demonstrated how discursive governance techniques such as ‘story‐telling’, benchmarking, and policy transfer have been pivotal in the activation, circulation, and performance of those spatial imaginaries and their transformation into temporarily dominant visions for strategic urban interventions aimed at repositioning urban actors, spaces, and activities. While spatial imaginaries can be related to differently framed global aspirations, the effects of spatial political projects on urban governance and investment trajectories differ significantly across space. Theoretically, the paper stresses the importance of particular conceptions of territorial relations and time‐ and place‐specific institutional mediation in shaping context‐dependent discursive material governance alignments.  相似文献

Personal travel time in U.S. urban areas has been stable, clashing with the assertion that urban sprawl greatly lengthens travel. Average commute time rises by 7.7 percent with each cross‐sectional doubling of Metropolitan Statistical Area (MSA) jobs. Using the RELU‐TRAN structural computable general equilibrium model of the Chicago MSA, we simulate the equilibrium effects of a 24 percent population increase projected from 2000 to 2030 by the Chicago Metropolitan Agency for Planning. If no new road capacity is added, then congestion per mile increases. Although the urbanized land area increases by 19 percent, indicating sprawl, the vehicle miles traveled (VMT) per car‐trip decreases by 1.31 percent and the VMT per car‐trip to work decreases by 2.78 percent. Car travel time increases by only 6.25 percent and commuting time by only 4.54 percent, from 30.3 minutes in 2000 to 31.7 in 2030 or 3.4 seconds per year. We further explore the effects of new road capacity, gasoline prices, public transit speed, fuel economy gains, limits on suburban construction, and importantly, the cross‐elasticity of public transit use with respect to car times. The availability of public transportation, economizing on nonwork travel, and land use adjustments that increase job‐residence proximity keep times stable.  相似文献

ABSTRACT. Until the last third of the twentieth century, Britishness figured prominently in the national identity of Australians. Many scholars of Australian nationalism have assumed an inherent antipathy between British and Australian solidarities; others have appreciated that there was a degree of mutuality between the two; few have explained why. This article offers such an explanation. It focuses on the crucial nation‐building period twenty years on either side of the federation of the Australian colonies in 1901. Drawing on ethno‐symbolist approaches to nationalism, it argues that Britishness provided the necessary ethno‐cultural foundations for Australian nationhood, the only available repertoire of myth and symbol that could fulfil the nationalist aspiration for unity. Yet Britishness in the antipodes was significantly different to that of the British Isles, as were the civic/territorial components of Australian conceptions of nationhood, giving rise to a distinctive British‐Australian composite nationalism.  相似文献

In recent years, aridity and drought have become crucial issues at the global scale because of their environmental and socio‐economic implications. On the one hand, aridity causes a reduction in the biological and economic productivity of terrestrial ecosystems, and represents a serious threat to ecological, biogeochemical, and hydrological processes. On the other hand, human use (and abuse) of vulnerable dry land ecosystems may lead to unsustainable land management. Based on these considerations, this paper analyses the recent land cover changes observed in Latium (Italy) during the exceptionally dry period 2000–2007. More than 50% of the area investigated was classified as dry in 2004–2007 compared with 0% in 2000–2003. Moreover, climatic aridity impacted differently on semi‐natural, agricultural, and built‐up land. These findings illustrate a possible scenario for suburban Mediterranean regions: increasing aridity (mainly due to rising temperatures) mainly impacting on peri‐urban land.  相似文献

Our aim in this article is to lay some statistical and theoretical foundations for an understanding of Italian post-war economic growth, by devoting special attention to what has happened in the hundred different “Italies” that go to make up the mosaic of this country. We have concentrated our analysis on comparing “areas of large enterprise” with “industrial districts” through a distinction between district provinces (IDPs), large enterprise provinces (LEPs) and other provinces (OPs). We investigate manufacturing industry by means of in depth analyses of trends in employment and value added, as well as through breakdowns of export flows and income and prosperity levels. Since the end of World War II it appears that Italian economic growth has largely been formed by the constant, massive flow of exports of personal and household goods and light mechanically-engineered products, that a sizeable flow of exports is attributable to growth in the industrial districts, and that although the income gap between the different parts of the country has not been eliminated, growth by the industrial districts and the policy of industrialization in Southern Italy have together engineered a major territorial dispersion of both light and heavy industry. However, heavy industry and high-tech large Italian companies have found increasing difficulties and even lost many of the positions they once held. Our survey indicates that a policy for industrial development in Italy must take account of the weakness of the heavy industry sector along with the features and requirements of industrial districts.  相似文献

Knowledge intensive business services (KIBS) are believed to be one of the main drivers of technological change, innovation, and economic progress. Although firm foundations play a crucial role among KIBS, entrepreneurship research has hardly ever investigated the sector. As firm founders in early stages of their firms' development mostly draw on regional resources, and as the provision of the services is an interactive process, “proximity” between the different actors of the particular territorial innovation and production system clearly matters. This contribution analyses the interrelationships between KIBS foundations and their respective innovation and production systems by performing qualitative and conceptual in-depth studies of three German metropolitan regions.  相似文献

The idea of the Third Italy has achieved an iconic status in geography. It has come to represent one of the main geographical manifestations of the so‐called second industrial divide between Fordist mass production and flexible specialisation. Yet the idea has received limited critical attention since acquiring its elevated status. It deserves to do so, because it involves confusing a localised model of economic development with the economic character of a larger geographic region. Examining province level export data for the years 1985, 1991, 1995 and 1999 for both total exports and two key sectors using exploratory spatial data analysis, provincial rankings and LISAs (local indicators of spatial association) suggests that the export‐based homogeneity and dynamism of the Third Italy can be exaggerated. Italy's urban hierarchy, particularly the centrality of Milan, continues to play a significant role in the Italian economy. Common use of the term ‘Third Italy’ confuses an economic process with a specific geographical configuration.  相似文献

Agglomeration can be caused by asymmetric information and a locational signaling effect: The location choice of workers signals their productivity to potential employers. The cost of a signal is the cost of housing at that location. When workers' marginal willingness to pay for housing is negatively correlated with their productivity, only the core‐periphery (partially stratified) equilibria are stable. When workers' marginal willingness to pay for housing and their productivity are positively correlated, there is no core‐periphery equilibrium. The urban wage premium is explained when there is a core‐periphery equilibrium. Furthermore, location can at best be an approximate rather than a precise sieve for high‐skill workers.  相似文献
