The objective of this critical review is twofold. Firstly, we intend to tackle a number of assumptions that view the Greek crisis as the result of a marked resistance to (neoliberal) structural reforms and the failure to engage constructively with the challenges of globalisation. Instead, we argue that Greece was set on a neoliberal trajectory much before the crisis erupted, and that it is precisely this sustained neoliberalisation process – rather than its absence – that lays behind much of Greece’s current troubles. Secondly, we attempt an assessment of the prospect that SYRIZA’s victory may be signalling the start of a counter-neoliberal mobilisation. Drawing on the work of Brenner and others, we identify four alternative scenarios – capitulation, divorce, compromise, transformation – and discuss their implications for Greece and the Eurozone. 相似文献

Anti-poverty politics in Toronto and Mexico City 总被引：1，自引：0，他引：1

In recent years, governments at different scales in both North and South have been experimenting with alternative methods of alleviating poverty, and redesigning social welfare regimes. While these changes are not entirely congruent across regimes in North and South, there are interesting points of overlap and intersection. The article lays out three broad alternatives to “roll-back” neoliberalism: intrusive liberalism; inclusive liberalism, and a renewed version of social citizenship. It then lays out how these alternatives have played out in anti-poverty politics in Toronto and Mexico City, two sites where creative strategies contesting neoliberalism have been pursued. While both cities occupy a critical place within their respective political economies, they are not usually compared because of their very different positions in the North American division of labour. Yet, as we argue, they face similar challenges in the form of poverty reduction strategies at the national scale that are based on neoliberal principles that do little to meet the needs of their inhabitants. In response, both cities have provided a site for mobilising resources behind alternative anti-poverty policies, inspired by the principles of social citizenship. 相似文献

The empirical Darcy's law of water transport in porous media, Fick's law of chemical diffusion, and Fourier's law of thermal transport have been widely used in geophysics/geochemistry for over 150 years. However, the strong couplings between water, temperature, and chemicals in a membrane porous medium have made these laws inapplicable and present a significant hurdle to the understanding of multiphase flow in such a material. Extensive experiments over the past century have observed chemical osmosis and thermal osmosis, but a model for understanding their underlying physicochemical basis has remained unavailable, because of the highly cross‐disciplinary and multiscale‐multiphase nature of the coupling. Based on the fundamental principles of nonequilibrium thermodynamics and mixture coupling theory, a rigorously theoretical and mathematical framework is proposed and a general model accounting for all of the coupled influences is developed. This leads to a simple and robust mathematical matrix for studying multiphase couplings in a membrane porous medium when all chemical components are electrically neutral. 相似文献

Increasing penetration by the market into the governing of agri-environments, and the use of market-oriented approaches in an attempt to produce more sustainable outcomes, is a characteristic feature of what scholars have called the ‘neoliberalisation of nature’. While accepting that neoliberal forms of governing tend to extend market relations into new domains, a number of scholars have argued that they may at the same time create spaces of resistance, open up progressive political possibilities, or incorporate alternative rationalities of governing. This literature has so far focused primarily on the policy and/or programme level with limited connection made to the growing body of research that explores landholder responses to specific market instruments. We address this gap by focusing on a market instrument – Wimmera Habitat Tender – in the State of Victoria, Australia, which aims to provide incentives for farmers in managing native vegetation. This case study explores how a specific tender-based market instrument seeks to construct natural resource managers as neoliberal subjects, as well as the complex ways in which farmers contest or resist the neoliberal governing of their agri-environmental practices. Through our analysis we contend that closer scrutiny of how the techniques underpinning market-based environmental instruments are taken up or resisted contributes to a more robust understanding of the environmental possibilities created by market instruments, as well as the challenges involved in attempts to neoliberalise nature. 相似文献

This article examines changing water governance modalities in the context of the neoliberalization of nature. Specifically, it focuses on Brazilian water sector reforms passed in 1997 that mandate decentralized and participatory decision-making at the river basin scale. Critics have suggested that rescaling, decentralization, and participatory governance mechanisms – supposedly intended to render decision-making more equitable, accessible, and relevant – can serve to legitimate, facilitate, and thus further embed processes of neoliberalization. Examining the impact of Brazil’s water sector reforms on the state–society relationship, this article presents a case study of water governance in the São Francisco River Basin and finds that the reforms – despite their neoliberalizing potential – have not significantly contributed to the neoliberalization of governance therein. Instead, water governance continues to be characterized by longstanding patterns of traditional elite control. Through an institutional and socio-natural analysis, this article describes and accounts for the continued dominance of these patterns relative to neoliberalization and explores activists’ efforts to use water sector reforms to pursue more progressive possibilities. The article concludes with a discussion of the implications for variegation and contestation in ongoing debates over neoliberal natures. 相似文献

On August 4, 2014 the tailings pond failed at the Mount Polley copper, gold, and silver mine in British Columbia. The dam failure was amongst the largest recorded, and led to widespread debate in the province concerning weak environmental law and the effects of deregulation. This paper examines the changing role of the law in British Columbia around mining and the environment in relationship to the Mount Polley disaster. It draws on the work of the early Soviet legal theorist Evigny Pashukanis to help understand law’s role in the commodification of nature. Pashukanis suggests a legal analysis of the commodity form and a study of laws role in commodification. However, contemporary law departs from the rigid and formal property and contract principles that Pashukanis considered, and now responds to shifting social conditions, technologies and environmental concern. Yet even today, Pashukanis remains relevant, and provides a starting point for analysis of how nature is commodified. His work points to a study of the multiplicities of, and variegated legal geographies of, commodity forms. 相似文献

Trans-nationally-scaled, multi-stakeholder, non-governmental product certification systems are emerging as important elements of neoliberal environmental governance. However, analysts question the extent to which they represent effective alternatives to the damaging impacts of neoliberalized, global production. They call for work examining the environmental politics arising in these new arenas of regulation, where social movements advocating environmental conservation and social justice interact with business interests in debates over how to use neoliberal tools to govern global commodity chains. This article examines The Forest Stewardship Council (FSC) process to revise tree plantation certification standards. First, it considers the political process surrounding standard-setting and argues that tensions between rigor, legitimacy, and acceptability restrain the political struggles over standards within voluntary, multi-stakeholder environmental governance organizations. It proffers findings at odds with the expectation that mainstreaming diminishes the rigor of social and environmental standards. Second, it speculates on the implications of this form of neoliberal environmental governance for promoting more sustainable productions of nature. The review process failed to adequately consider the role of plantation certification in strategies for natural forest conservation. Neither did it adequately consider vital questions of the appropriate scale and location of production, the community actors best suited to deliver both forest conservation and poverty alleviation, or the need to encourage reduced consumption. The reliance on a neoliberal framework and values limits the scope of action. These contradictions suggest that FSC certification is an important part of what needs to be a broader movement questioning current practices of environmentally damaging production and complicit, complacent, consumption. 相似文献

This paper traces attempts to foster local, sustainable food projects in Niagara, Canada as part of community economic development (CED) projects during two distinct periods of provincial governance. In the first period (1990-1995), social democratic government support for local sustainable food projects through CED can be understood as neocommunitarian in nature. During this time there was a concerted attempt to link local people with access to local food and also to support a relationship between local food projects and agri-tourism. I argue that this neocommunitarian policy was an accommodation to a wider and more global neoliberal hegemony and was underlain by a romanticism of petty commodity production and a tenuous link to social and ecological sustainability. In the second period of governance (beginning in 1995) the progressive conservative government led by Mike Harris pursued particularly virulent, revanchist forms of neoliberal governance. With many of their state supports slashed, Niagara NGOs and activists turned, and were pushed, to more market-led, elitist forms of local food projects and agri-tourism. In these latter food projects, the practices of ecological and social sustainability were significantly hollowed out and their local and light green nature was harnessed as accumulation strategies. The paper is based on interviews conducted in the year 2003 with people involved in various urban and rural food projects (including community gardening, community supported agriculture, local/seasonal cuisine, organic/ecological farming and food box programs). 相似文献

In most Latin American countries, issues concerning water governance and control also reflect broader conflicts over authority and legitimacy between the state and civil society. What lies behind the diverse water policy reforms is not simply a question of governing water affairs but also a drive to control or co-opt water user groups. This paper examines the efforts by the present Ecuadorian government to ‘control water users’ through new forms of ‘governmentality’ (Foucault, 1991). We use the ‘cathedral and bazaar’ metaphor (Lankford and Hepworth, 2010) to illustrate government rationale and practices in water governance shifts in the last decades. We analyze how Rafael Correa’s government sets out to reshape the relations between state, market and society. In its ‘Twenty-first Century Socialism’ project, based on a proclaimed ‘Citizen Revolution’, actual policy reform does not reverse but rather transforms the process of neoliberalizing water governance – creating a hybrid bazaar-cathedral model. We argue that the current water govermentality project implements reforms that do not challenge established market-based water governance foundations. Rather it aims to contain and undermine communities’ autonomy and ‘unruly’ polycentric rule-making, which are the result of both historical and present-day processes of change. Interestingly, water user federations that emerged during the neoliberal wave of the last two decades now claim water control space and search for new forms of democratizing water governance. They act as agents who fiercely – yet selectively and strategically – oppose both elements of the State-centered (cathedral) and market-based (bazaar) water governance models. 相似文献

This article critically investigates recent water governance shifts, particularly constitutional changes implemented in several Latin American countries that highlight a ‘right to water’ as well as recent efforts that invoke such a right in conjunction with bans on private water provision (e.g. Uruguay, Ecuador, and Bolivia). Drawing on legal research, document review, and interviews, the article investigates the historical, political and discursive scaffolding of these constitutional changes in several case study contexts, including attention to implementation issues and ongoing challenges following the reforms. Placing these shifts within the broader context of neoliberalization of water governance of the past several decades, the analysis attends to both the specific historical–contextual formations that are important to understand the constitutional reforms, as well as the ways these changes might be usefully understood as connected to broader political and discursive shifts and movements. Highlighting similarities and differences across the cases allows us to make conceptual contributions to debates on variegation of neoliberalized natures, as well as to discussions of alternatives to neoliberalism and postneoliberalism. We argue that although many of these reforms are partial, and not wholly resistant to neoliberalism, they are nonetheless significant for politics and debates related to ‘alternatives.’ Apart from resisting particular aspects of earlier neoliberal reforms, they are also important to stake new discursive and policy terrain on alternative priorities and uses of water. Further, the reforms also offer points of resistance to the influence of international financial institutions, or of transnational corporations. 相似文献

为了分析排水措施对淤背体固结特性影响,以黄河山东某堤段为研究对象,数值模拟研究在淤区设置碎石盲沟排水方案,淤背施工过程中以及施工完成后放淤固堤工程孔隙水压力消散过程,探讨淤背体排水固结规律。研究结果表明,与无排水方案相比,该排水方案可以加速淤背土体固结,减小水分对黄河大堤堤背的渗入,降低围堤内的浸润线。在与试验区相似的施工工况条件下,建议3m左右淤土厚度布置一层排水盲沟,排水效果较好。数值计算结果与实际情况相吻合,可为黄河放淤固堤工程加快淤背体排水提供参考。 相似文献

Poverty and citizenship: Sociological perspectives on water services and public-private participation 总被引：1，自引：0，他引：1
José Esteban Castro 《Geoforum》2007,38(5):756-771
This article focuses on the arguments used to support private sector participation (PSP) in the provision of water and sanitation services (WSS) since the 1980s. It addresses the following questions: what was the historical evidence informing the claim that promoting PSP would be the best instrument for reducing water poverty? What are the principles that provided the foundation for this claim? And, what has been the empirical record of the resulting WSS policies? It argues that early neoliberal WSS policies since the 1980s were not intended to expand services to the poor. A pro-poor rhetoric was added to these policies since the 1990s, probably as a result of increasing citizen unrest in developing countries and the failure of privatized WSS projects in the Americas and Europe. However, the claim that PSP can provide the solution to public sector failure in extending coverage of essential WSS to the poor has little ground both in the theoretical literature and in the historical record. As could have been expected from the accumulated knowledge about the relationship between market-driven WSS and the poor, the recent experience with PSP projects has been disappointing. In practice these policies not only have failed to extend these essential services to the poor but have also contributed to deepening existing inequalities of power resulting in the weakening of state, local government, and civil society capacities to exercise democratic control over private water monopolies in most developing countries. Reversing this imbalance is one of the crucial challenges ahead in order to achieve the Millennium Development Goals. However, the article argues that the inertial forces set in motion by the neoliberal model of water policy based on market-centred governance of water and WSS remains the crucial obstacle for the achievement of the goals. 相似文献

In recent years, many geographers have examined the ways that the production of nature has changed as a result of neoliberal practices. In this paper we examine a conflict in South Korea that started when some Chinese-cabbage seeds were affected by a virus, causing crop failure. This failure came shortly after liberalization in the Korean seed industry led to foreign ownership of the firm that sold the seed. We focus in particular on the farmers’ creative political responses - and their subsequent defeat in court. Drawing on Antonio Gramsci’s insights on politics, science, and law, we examine how the seed failure came to be evaluated through scientific and legal practices. We argue that the adjudication of the truth of the seed failure through science and law reveals how socionatures are contested under prevailing hegemonic conditions. These conditions are both general and specific: although law and science are relatively hegemonic spheres of truth-production in all capitalist societies, the ways that the seeds were disputed and evaluated were distinctly Korean. 相似文献
