Indian metropolises have witnessed the growth of ‘new towns’ on their peripheries over the past two decades, which have attracted investment as well as affluent residents. Most research on new towns examines the contentious politics of land acquisition and development, but less is known about urban governance and everyday life. This article focuses on solid waste management in Noida, a new town on the periphery of Delhi that has been unable to develop a large-scale waste management system, and we have two main foci. First, we show that the municipal government has sought to regulate waste collection, while waste processing and disposal have remained unregulated and this has discouraged the entry of medium and large-scale private enterprises. Second, we explore the contentious politics surrounding actually existing waste management practices that have emerged in the absence of significant public or private investment. Most waste is managed by small- and medium-sized enterprises in the informal sector, so associations that represent the so-called ‘new’ middle class must interact with informal-sector waste workers. These interactions result in moderately high levels of waste collection but waste disposal remains haphazard and this exposes the limits of the new middle class’ control over urban space. Ultimately, we show how municipal governance and the actually existing politics and practices of waste management contribute to the production of Noida’s socio-spatial landscape. 相似文献

The migration of lifestyle-orientated landholders (amenity migrants) to rural landscapes is resulting in the production of new rural ecologies. To date, the future implications of these ecologies for environmental management have been framed largely in ‘traditional’ conservation biology terms, focusing on how we can conserve or restore natural environments to a past ecological benchmark. However, the Anthropocene provides an opportunity to critically examine how we can progress environmental management in a way that locates ecologies as emergent products of human–environment interaction through time. We extend from Tim Ingold’s work on wayfaring to position people and plants in environmental management as cohabitants who are traversing a world that is continually in the making. We conducted qualitative research in the hinterlands of Melbourne, Australia, involving narrative interviews with landholders and walking their property with them, using a form of participant observation called the ‘walkabout’ method. We found that the conservation aspirations of amenity migrants were mediated by the landscape histories that were embodied in the plants they engaged with on their property. These embodied landscape histories served to structure the trajectory of ecological emergence in which landholders were a part. We develop the concept of ‘landscape legacy’ to explain how past actions and future aspirations come together in management practice to produce novel and often unanticipated ecologies. Landscape legacy grounds the Anthropocene in everyday environments, capturing the need to progress environmental management as a wild experiment in rural-amenity landscapes, focusing on ecological form, function, relationship and process. 相似文献

The increase in the volume of waste materials discharged to the environment and deterioration of environmental quality in urban areas have been an issue of major concern for many governments in developing countries. To improve effectiveness and efficiency in the delivery of waste management services some of the governments have involved the private sector. This study uses binary choice model to examine urban residents’ perceptions regarding solid waste management that involves the private sector and what could be done to improve the waste management services. The data were generated from survey conducted in 238 households in Ilorin in southwest Nigeria. The results show that most of the respondents were not satisfied with solid waste management in the Ilorin. Binary logit model estimates reveal that the respondents’ perceptions regarding waste management were determined by income, travel time to dump site and marital status, as well as awareness of laws regarding waste disposal and activities of sanitary inspectors. For solid waste management in urban areas to be sustainable, it requires participation of the government, private sector and residents. The results generated from this study can help waste management authorities in designing a more sustainable waste management strategy in Ilorin, as well as in other cities that have similar conditions. 相似文献

Malaria management involves the continuous calibration of micro-environments, namely of the entangled habitats of mosquitoes, parasites and humans. This article focuses on humans and mosquitoes as unruly actors of environmental management. Drawing on economic sociology, I show how framing mosquito nets as ‘humanitarian goods’ disentangles particular economic and ecological realities. Juxtaposing politico-economic processes of mosquito net production and distribution with the emergence of insecticide resistance in mosquitoes I show how their disentanglement creates unintended social and disease realities. This suggests rethinking the spatio-temporal politics of environmental management of mosquitoes and malaria, and nuances the patterns of how exactly humanitarian goods ‘do good’. 相似文献

In 2014, Tesco – one of the world’s largest food retailers – revealed that it had generated almost 57,000 tonnes of food waste in its UK operations over the previous twelve-month period. This shocking statistic added to existing evidence of a significant environmental and social problem in the UK and across the world. This paper utilises convention theory to examine the role of major retailers in the context of this global problem and assesses their motivations for acting on food waste. Drawing on interviews with key stakeholders (including major retailers), the analysis investigates their main justifications for action on food waste. It finds that retailers mostly appealed to three conventions or ‘orders of worth’ (civic, market and opinion) and used these as a basis for their commitment to food waste reduction. We argue that the combination of these different justifications is feasible and necessary in the context of the retail sector but that they may also lead to some unintended consequences (in the retail sector and beyond). Crucially, we demonstrate how the dilution of civic justifications (by their financial and reputational counterparts) might produce negative outcomes and inaction as retailers attempt to adhere to the so-called ‘food waste hierarchy’. The paper highlights the continuing significance of convention theory as a framework for analysing possible responses to the social and environmental challenges confronting global agro-food systems. 相似文献

Despite our declared era of ‘Big Data,’ we lack information on the flows of energy, water, and materials that support modern societies. These data are essential to understand how ecologies and the labor of people in far flung places supply urban areas, as well as how these resource flows are used by whom, where, and for what purpose. Like other places, the state of California is struggling with issues of data privacy and access. Water scarcity and the state’s commitments to greenhouse gas emission (GHG) mandates raise the issue of consumption and the unequal burdens that derive from it. These mandates have unveiled the lack of comparable and verifiable data to understand crucial production-consumption dynamics. This paper illustrates how spatially-explicit big data can be harnessed to delineate an urban political-industrial ecology of resource flows. Based on research using address-level energy and water use consumption data for Los Angeles County, the analysis reveals how the region’s wealthy residents use a disproportionate share of the water and energy resources. The paper also identifies structural obstacles to increasing fees and taxes or altering property rights that would reduce this consumption and foster more equitable resource use. This study has implications for theory, method, and policy related to urban sustainability, which is unobtainable without first unraveling the political-industrial ecology of the material basis of urbanization processes. 相似文献

In recent years, solid waste management (SWM) policies and programmes have received lots of attention in the menu of most
political leaders in developing countries. However, these concerns often focus on the efficiency criterion. Even that, efficiency
is only narrowed down to the removal of waste from residential areas without much concern for either its safe disposal or
its impact on the environment in case of improper waste disposal. There is little attention on reducing waste flows (through
reuse, recycling and composting), or exploiting its economic value. The results of such blatant omission include threats to
public health, environmental deterioration and lack of attention to waste as a resource. This study examines the key barriers
to effective SWM practices in the Greater Accra Metropolitan Area and attests to the marginalization of waste treatment and
disposal practices. It recommends that these missing links must be addressed through network service arrangements to ensure
sustainable urban environment management. 相似文献

Over 24 million plastic bags are consumed in Kenya monthly. More than half of the bags end up in the solid waste stream. Plastic bags now constitute the biggest challenge to solid waste management in Nairobi, the capital of Kenya and home to three million people. As a result, plastic bag waste has attracted great political and public attention, especially because the waste has myriad unique environmental problems. This paper seeks to unravel the problem of plastic bag waste in Nairobi through an urban political ecological perspective. Urban political ecology has done much to excavate economic, political, and cultural processes, as well as ecological dynamics that create and re-create urban environments. Little has been done in this context with respect to urban solid waste problems, with the exception of urban political ecology of environmental justice. However, research done within the context of urban political ecology of environmental justice has mainly focused on solid waste problems in the Western World, particularly USA. Drawing on research conducted in Nairobi, as well literature on business and politics, and solid waste management in Kenya, this paper examines the nature of plastic bag waste problem, its political–economic roots and implications for environmental justice. 相似文献

This paper examines how environmental resources are measured and quantified as objects of environmental science and management and how lay knowledge-producers participate in this process, alongside the state. Using a case study of recreational angling, I show how fish in English rivers and lakes are counted and anglers act as lay or amateur knowledge-producers in the state’s metrological knowledge-practices. As embodied measurement instruments, anglers create data about themselves (as ‘effort data’) and about fish (as ‘catch returns’). These data are combined with other forms of data produced by the Environment Agency in England and Wales and used for fisheries management, thus shaping water bodies and fish ecology. I show how, to support environmental measurement, the state manages not only the environment and fish, but also anglers as lay knowledge-producers, using both regulation and economic incentives; in response, anglers also use data reflexively and strategically. I therefore emphasise the heterogeneous co-productions of environmental measurement as amateur–professional, human–animal and organic–technological, and show how measuring and managing water ecologies also involves measuring and managing humans. 相似文献

Access to safe and adequate water and to sanitation has been a global developmental priority due to their intrinsic impacts on the achievement of the sustainable development goals. Despite the implementation of several measures to improve access to safe water and sanitation, urban dwellers in Ghana struggle to acquire water and access sanitation facilities. This paper identified and examined the vulnerable conditions of households to environmental inadequacies of potable water and sanitation and measures aimed at reducing the risks associated with them in the Ashaiman Municipality. The study revealed that, access to adequate water supply was not necessarily dependent on the physical location of house units, but on factors such as lack of building permit, financial constraints, rental conditions, administrative procedures and ill-suited housing arrangement. Inadequate solid and liquid waste management practices and poor drainage systems were major problems identified in the Municipality. The paper argues that water, drainage systems and logistics for waste management in deprived communities must be provided by the local government and service providers through public–private partnership agreements. We conclude that, planning rules, regulations and procedures should be strictly adhered to and vigorously enforced by the Municipality in order to have a well-organized and planned urban environment. 相似文献

Young adults in the Global North occupy a contradictory environmental identity: they are purportedly more environmentally concerned than older generations, but are also labelled hedonistic consumers. Most studies have focused on young adults still residing in parental homes, neglecting that Generation Y (born between 1975 and 1991) has ‘grown up’. The consumption patterns and environmental implications of their newly established households demand scholarly attention. Through a large-scale household sustainability survey, conducted in Australia, we have uncovered important inter-generational differences in environmental attitudes and everyday domestic practices. We found that generational cohorts hold distinct environmental attitudes. Younger households were most concerned with climate change, and least optimistic about future mitigation. However, generational differences influenced everyday domestic practices in more complex ways. All households engaged extensively with those ‘pro-environmental’ practices that reflected established cultural norms, government regulations and residential urban form. For other pro-environmental practices there were clear differences, with Generation Y households being the least engaged. A widening ‘value-action gap’ was apparent across our sample population, from oldest to youngest. However, rather than reflecting Generation Y’s supposed hedonism, we argue that this gap reflects generational geographies: how lifecourse intersects with housing and labour markets and norms of cleanliness to shape everyday domestic practices. Our research illuminates the shortcomings of a one-size-fits-all approach to household sustainability. The young adult stage is a time of transition during which homes and independent lifestyles are established, and practices are altered or become entrenched, for better or worse. 相似文献

In this article we respond to and challenge Jørgensen’s criticisms of the concept of rewilding in her paper ‘Rethinking rewilding’, published this year in Geoforum. Jørgensen argues that ‘rewilding’ has become a ‘plastic word’, one that has been stretched to the point where it lacks definitional precision, at risk of becoming ‘the go-to blanket solution to environmental problems’. She also argues that the practice of rewilding is premised upon the dissociation of humans from the rest of nature and reproduces anti-human Nature–Culture binaries, rightly lambasted by critics of wilderness narratives in conservation practice. In response to these criticisms we challenge Jørgensen on two points. Firstly we argue that the problems of ‘plasticity’ and definitional imprecision can be rectified by highlighting and foregrounding the quality that we believe is at the core of all rewilding definitions and efforts: non-human autonomy. Secondly, we challenge Jørgensen’s broad claim that sees the collapse of ‘rewilding’ into anti-human wilderness management. We do so by reflecting on two points; the dynamic human–non-human entanglements embedded within rewilding practice(s) and by arguing for rewilding as a ‘wild experiment’. We make these points through the examination of two actually existing examples of rewilding. 相似文献

Recent scholarship examining environmental governance and solid waste management (SWM) in Hawaii has demonstrated the complexities of managing refuse in a remote, ecologically sensitive archipelago. Despite decades of calls for intensive recycling, composting, incineration, and other non-landfill disposal technologies, most islands of Hawaii continue to rely on sanitary landfilling. On Maui, a minor bureaucratic scandal centered on landfill permitting triggered the formation of an ad hoc entity intended to change SWM once and for all – the Solid Waste Resources Advisory Committee (SWRAC). I mobilize scholarship on waste governance, and in particular the ‘modes of governing’ framework to interrogate the decision-making processes of the SWRAC, evaluate their outputs, and consider the reasons for their ultimately limited impact on SWM governance on Maui. Based on a close reading of SWRAC meeting minutes and documents, I identify several factors, including the lack of clear goals or targets for SWRAC activity; a flawed, consensus-oriented decision-making process; and a failure to contextualize SWM within the broader environmental and cultural terrain of Maui. Taken together, I contend that these three problem areas underline the significance of seriously incorporating and harmonizing competing conceptions of ecological identity into both the ‘modes of governing’ framework and the scholarship of environmental governance more broadly. 相似文献

This article focuses upon informal e-waste recyclers who subsidise the environmental costs of Bangalore’s information technology boom. It illustrates how improvement schemes devised by development agencies, to make Bangalore’s e-waste disposal practices more sustainable, reproduced the effects of bourgeois environmentalism and effectively cast off informal recyclers from having a substantial role in the city’s emerging regime of e-waste management. Being cast out and rendered superfluous has been a deeply degrading experience for Bangalore’s informal recyclers. In order to foreground this experience I draw upon the notion of abjection and show how informal recyclers are constituted as abject residents who must be confined to collecting and processing waste from the most marginal frontiers of the city’s e-waste circuits. 相似文献

In spite of continued mass urban protests in post-apartheid South Africa, few are the social movements or individuals which openly disengage from the dominant and former liberation party, the African National Congress. Many authors have analysed this paradox as a two-pronged strategy, ‘the brick’ and ‘the ballot’, to try and influence public policy. However, these two political positions become increasingly contradictory and difficult to hold together, as the ANC becomes more and more intolerant towards social movements. This paper, using the example of women’s contention about water commodification in Phiri (Soweto), examines how activists shape their opposition whilst still stating their affiliation to the ruling party. They manage these contradicting political loyalties through a variety of tactics exonerating the ANC from the blame of urban mismanagement: contrasting the current ANC with the ‘real’ ANC of the past – to which they remain faithful; and blaming the ‘deployees’ of the ANC at the local level for betraying the ‘real’ ANC at the national level. These tactics however may be short-lived as social movements upscale their action to the national level. 相似文献

Rubbly pahoehoe lava flows are abundant in many continental flood basalts including the Deccan Traps. However, structures with radial joint columns surrounding cores of flow-top breccia (FTB), reported from some Deccan rubbly pahoehoe flows, are yet unknown from other basaltic provinces. A previous study of these Deccan “breccia-cored columnar rosettes” ruled out explanations such as volcanic vents and lava tubes, and showed that the radial joint columns had grown outwards from cold FTB inclusions incorporated into the hot molten interiors. How the highly vesicular (thus low-density) FTB blocks might have sunk into the flow interiors has remained a puzzle. Here we describe a new example of a Deccan rubbly pahoehoe flow with FTB-cored rosettes, from Elephanta Island in the Mumbai harbor. Noting that (1) thick rubbly pahoehoe flows probably form by rapid inflation (involving many lava injections into a largely molten advancing flow), and (2) such flows are transitional to ‘a’ā flows (which continuously shed their top clinker in front of them as they advance), we propose a model for the FTB-cored rosettes. We suggest that the Deccan flows under study were shedding some of their FTB in front of them as they advanced and, with high-eruption rate lava injection and inflation, frontal breakouts would incorporate this FTB rubble, with thickening of the flow carrying the rubble into the flow interior. This implies that, far from sinking into the molten interior, the FTB blocks may have been rising, until lava supply and inflation stopped, the flow began solidifying, and joint columns developed outward from each cold FTB inclusion as already inferred, forming the FTB-cored rosettes. Those rubbly pahoehoe flows which began recycling most of their FTB became the ‘a’ā flows of the Deccan. 相似文献

This study contributes to the existent literature on neoliberal urban governance examining the process-based character of this formation. I maintain that neoliberal governance is a fluid and evolving formation which is continuously being constructed and reconstructed beneath a rhetorical veneer of inevitable emergence and permanence. In this context, this work examines the interconnections between neoliberal urban ascendancy, changing rhetoric and urban waste management policies, and waste pickers (cartoneros), in a case study setting, Buenos Aires. Since 2002, the neoliberal urban governance in Buenos Aires (its institutions, programs and policies) has mobilized different rhetoric and policies to negotiate the waste pickers’ “disturbing” and “dirty” presence in the streets. In that process, the waste pickers, originally marginalized and stigmatized by the neoliberal discourse, have been regulated and disciplined into legal and “well behaved” workers. I would argue that, regulating this activity does not entail giving the waste pickers an opportunity to become central actors in the future of urban waste management in the city. Rather, it is compatible with the logic of the local neoliberal urban projects, focused on disciplining the city’s physical and social landscape as new opportunities for growth and development continue to emerge. 相似文献

The increase in the popularity of using environmental design criteria in town and country planning has brought about the need to fully identify the principles to determine the best location of hazardous wastes to be landfilled. This environmental management issue has received considerable attention because of its applications in urban and rural infrastructure planning, industrial development planning as well as health, housing, transportation and agricultural schemes. This paper explains a method to determine how to locate suitable sites for hazardous waste landfilling area by using the site screening study. It demonstrates how the criteria such as geology, topography, land use, climate, earthquake and other related factors can be introduced into the overlayer technique to determine the suitable site selection in a region. The research was undertaken in the Southeastern Anatolia Project (known as GAP in Turkey) region where identifying the land resources is crucial for agricultural and water management purposes. The paper also explains the validity of the method employed on the site selection process for hazardous wastes. The introduced method may enable more accurate design procedure for planning in environmental management in future. 相似文献
