People’s reasons for visiting national parks have been well researched. So too have their park activities and how diverse activities potentially affect visitors’ park experiences (e.g. perceptions of overcrowding). Far less research has examined how park users’ environmental values might affect their perceptions of other users and the appropriateness of different activities – a potential source of conflict. Relationships between personal environmental values and environmental and social perceptions are complex and interactive in the context of park visitation. Visitors’ encounters with other users can powerfully affect their experience and enjoyment of parks, in turn reflecting such factors as values-related expectations and judgments in the context of national parks. Personal and social values may also play an important role in influencing whether different activities are perceived as ‘out of place’ in the context of national park place meaning, yet the conceptualization of values within geographic literature on parks remains comparatively weak.This paper utilizes a definition of values, derived from a concise review of the geography and social psychology literatures, to explain the results of survey research we undertook within national parks in Queensland, Australia. We use a ‘values-behavior hierarchy’ conceptual framework to consider how the personal environmental values of a sample of park visitors (n = 404) potentially affected patterns of park visitation, user activities, and user conflicts. Findings suggest that visitors’ environmental values shaped how they perceived other park users and the appropriateness of their activities. This has international implications for geographic research and other disciplines and professions involved in national park visitation, park use, and human impacts, on and of these powerful places.  相似文献

This paper examines the variegated natures of (post-)neoliberal environmental governance in Latin America using environmental crisis as an entry point. It examines the institutional measures put forth by Ecuador’s government, in concert with other actors, to contain and manage the damaging effects of an insidious palm oil plant disease known as Pudrición del Cogollo (PC). Using empirical data collected through qualitative means, my analysis demonstrates that nature’s biophysical processes – in particular, disease ecologies – can play a crucial role in the pursuit and achievement of national accumulation goals. Specifically, I argue that the ecologies of the PC crisis have been rendered functional to the Ecuadorian government’s current political and economic strategies of intensified accumulation and market competitiveness. By making environmental crisis the basis of key accumulation strategies, the state is able to convert negative environmental outcomes into opportunities for profit-generation. Utilizing the notion of the ‘ecological fix’, this paper reveals two major conclusions: (1) plant health emergencies and the actions used to mitigate environmental crises are not only challenges but opportunities that can be mobilized to support further accumulation strategies and (2) the study of PC and Ecuador’s palm oil industry provides new fruitful terrain to examine the connections between the deepening variegated effects of neoliberalism through nature and environmental crisis solutions in Latin America.  相似文献

This article sets out an agenda for research that (re)connects research on children’s geographies and childhood studies with studies of spatial literacy. Research on children’s environmental cognition and, latterly, spatial literacy, has been artificially and problematically separated from the majority of research in childhood studies. Our fundamental aim in this article is to argue for – and to evidence – greater attention to how spatial literacy and children’s everyday lives are embedded in one another. To support our broader call for a synthetic research agenda, we draw on some more focussed, qualitative empirical material taken from a large-scale project about children’s mobilities and everyday lives in newly-built urban communities. Our analysis focuses upon children’s interpretations of Global Positioning Systems (GPS) tracks of their mobilities, set against a background of Google Earth imagery. In doing so, we showcase one suite of ways in which research on environmental cognition and children’s geographies might proceed together. We demonstrate that children not only displayed analytical skills (for instance, in relation to scaling effects and pattern recognition) but that many also exercised higher-level, critical analysis, especially in relation to errors on Google Earth outputs. Simultaneously, we interrogate the recursive articulation of a range of qualitative indicators of spatial literacy, with children’s everyday mobilities, routines, emotions and memories. The paper analyses how new conceptual languages and technologies being propounded by spatial literacy scholars could afford a more enriched understanding of key contemporary concerns for children’s geographers, and, recursively, what spatial literacy scholars might gain from engaging with (especially qualitative) research prompted by those concerns.  相似文献

In this article, I ethnographically examine “the biggest experiment in tropical conservation history,” an environmental management approach designed in Brazilian Amazonia. I focus on research conducted by scientists who support this approach using the results of their work at an open-air experiment. Drawing on this ethnographic study I critically revisit Bruno Latour’s deservedly influential ethnography of an open-air laboratory in Brazilian Amazonia. I also engage with his claim that open-air experiments constitute spaces in which scientists can avoid seeing the world as “Nature”—a gigantic collection of inert objects that experts sense they have to bring into order on their own. Latour shows that while working in their Amazonian open-air laboratory scientists perceived the forest as a network comprising human and non-human entities bearing creative capacities. He suggests that such experimentation enables humans to envision environmental management strategies based on human/non-human collaborations. In the open air, experts could thereby transcend the pervasive fatalism that plagues environmental policy circles and rekindle a more optimistic and enthusiastic stance toward environmental management. I argue that Latour’s is a visionary ethnography that anticipates contemporary trends in environmental management approaches. However, I also argue that his celebratory conclusions regarding open-air experimentation are misguided. I show that, while working in the open air, the scientists situated their work within capitalist experiments wherein humans and non-humans creatively collaborate in the construction of new, less inhabitable worlds.  相似文献

Multiple observations of the yellow hypergiant ρ Cas obtained in 2007–2011 in a wide wavelength range with spectroscopic resolving power R ≥ 60 000 have enabled studies of features of its optical spectrum in detail and brought to light previously unknown characteristics of the star’s extended atmosphere. The radial velocity measured from symmetric absorption lines of metals varies with an amplitude of about ±7 km/s around the systemic velocity V sys = ?47 km/s, due to low-amplitude pulsations of the atmospheric layers near the photosphere. At some times, a velocity gradient was observed in deep atmospheric layers of the star. A slight velocity stratification in the stellar atmosphere was detected for the first time, manifest as a difference of 3–4 km/s in the velocities measured from absorption lines of neutral metals and of ions. The long-wavelength components of split absorption lines of BaII, SrII, TiII, and other strong lines with low excitation potentials for their lower levels are distorted by nearby emission lines. It is suggested that the short-wavelength components, whose locations correspond to the narrow velocity range V r (blue) from approximately ?60 to ?70 km/s, are formed in a circumstellar envelope; one component of the D NaI doublet and the emission components of the FeII 6369.46 and 6432.68 Å ions are also formed there.  相似文献

Frame analysis has been widely employed to understand environmental conflicts. Such studies emphasize the internal dynamics of conflict and focus on how actors discursively struggle with each other in order to gain hegemony over the dominant discourse on the issue. In this paper, we argue that the explanatory power of framing theory could be enhanced by relating issue specific frames to the broader cultural context in which framing efforts are situated. In order to investigate the link between the success of framing strategies and the cultural background of such strategies, we suggest rethinking the concept of cultural resonance. We propose social representations theory as a novel way of understanding this cultural resonance of spatial and environmental frames. Based on a dispute over the management of a national park in the Netherlands, we empirically illustrate how contending stakeholders refer to different social representations of nature in the framing of local conflicts. A local protest group proves to be much more in touch with the views of the local community and is thus more successful in its framing of the dispute than the nature conservation agency involved. While the protest group uses a wide range of locally embedded representations of nature to enhance the currency of its framing efforts, the nature conservation agency responsible for the management of the forest refers to a much more limited range of representations. By making references only to the wilderness representation of nature, the cultural resonance of the agency’s framing efforts remains limited to those residents who adhere to this specific representation of nature. Consequently, this framing is not very successful among groups that adhere to other representations of nature, such as aesthetic or inclusive representations. Our analysis shows that combining framing theory with social representations theory enables one to disentangle the framing of environmental disputes from the more constant cultural values and opinions on which this framing is based.  相似文献

The authors identify and describe the following global forces of nature driving the Earth’s climate: (1) solar radiation as a dominant external energy supplier to the Earth, (2) outgassing as a major supplier of gases to the World Ocean and the atmosphere, and, possibly, (3) microbial activities generating and consuming atmospheric gases at the interface of lithosphere and atmosphere. The writers provide quantitative estimates of the scope and extent of their corresponding effects on the Earth’s climate. Quantitative comparison of the scope and extent of the forces of nature and anthropogenic influences on the Earth’s climate is especially important at the time of broad-scale public debates on current global warming. The writers show that the human-induced climatic changes are negligible.  相似文献

In this paper we employ rhetoric culture theory, and a case study of upland channel truncation in the UK, to explore the nuanced processes of negotiation associated with environmental decision-making. In contrast to much of the literature on rhetoric in environmental management, which focuses on the means by which decisions are communicated and justified to an external audience, we focus on the dynamics of interaction and persuasion in and amongst a small group of decision-makers, and how, despite initial misgivings and conflict, they arrived at a decision consensus. We reflect on the importance of the rhetorical situation as a determinant of action and demonstrate how antagonisms were caused by competing moral notions of environmental restoration. We show that consensus was finally achieved through a process of divergent reframing, as individuals reframed the problem according to their own prior values. The outcome, therefore, was a consensus of action but a divergence of opinion, which sheds new light on the role of reframing in environmental management. Finally, we argue for a better understanding of how nuanced interactional processes influence not only small-scale interventions, but all environmental decision processes.  相似文献

Satellite remote sensing technology has been widely used in environmental protection in China. Based on China’s environmental protection characteristics, this paper reviews the application advancements of optical, infrared, microwave and hyperspectral satellite remote sensing techniques in atmospheric environment, water environment and ecological environment, respectively, including the atmospheric environment monitoring of aerosols, particulate matter, pollution gases, and greenhouse gases; the water environment monitoring of water blooms water quality, oil spills, water pollution and drinking water safety; the ecological environment monitor of national nature reserves, environmental damages from mines development, soil contamination, urban/rural ecological environment and biodiversity richness. Furthmore, it summarizes the limitations and future directions of satellite remote sensing studies in China environmental protection. The paper specifically notes that the development of high-resolution satellite remote sensing technology, as well as the launch and use of China series satellites could significantly improve the level of government’s environmental management.  相似文献

We examine the effects of natural disasters on income and investment in China. Using macroeconomic province-level data and the provincial history of disaster exposure over the past two decades, we describe the relationship between disaster mortality and morbidity, disasters’ economic damages, government investment and regional economic activity, and infrastructure development. The Chinese government’s aggressive investment in post-disaster reconstruction is discussed, and the implications of this investment for post-disaster private sector economic activity are analyzed empirically. We further investigate the differential effects of natural disasters on economic activity in China’s diverse geographical regions.

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

In this critical review we reflect on findings from a socio-historical study of golf’s relationship with the environment. We focus especially on the golf industry’s pursuit of modernization from the early 1900s to the present. Golf’s quest to ‘be’ modern, we contend, has specifically constituted three particular ‘turns’: a first turn in the early 1900s involving the scientific rationalization of golf course development and maintenance; a second, ‘exemptionalist’ turn in the post-war years whereby science and technology fueled a perception of immense control over nature; and a third, more recent turn to ecological modernization (EM) whereby science and technology are leveraged toward environmental stewardship – or at least claims thereof. We ultimately argue that the golf industry’s recent adoption of EM principles in their environment-related work has political implications, as it ‘protects’ the industry from more radical environmental alternatives.  相似文献

High-accuracy multicolor light curves of the binary system HD 189733, which contains an exoplanet, are analyzed. We have determined the radii of the star and the planet in the binary system, as well as the orbital inclination. The limb-darkening coefficients of the stellar disk were obtained in 10 filters in the wavelength interval λλ = 5500?10 500 Å. The uncertainties of the fitted parameters were estimated using the differential-correction and confidence-area methods. The wavelength dependence of the limb-darkening coefficients is compared to the corresponding theoretical function for a model thin stellar atmosphere. We confirm the wavelength dependence of the exoplanet’s radius found by Pont et al. (at the 1σ level). The exoplanet radius increases with decreasing wavelength, which seems to argue for the presence of an atmosphere around the planet.  相似文献

The Beijing-Tianjin-Hebei (BTH) region is an important engine for China’s socioeconomic development. Timely and effectively assessing constraint factors of resources and environment is of great significance for the sustainability assessment and the sustainable development of this region. However, comprehensive assessment research considering key resource and environmental constraints are still lacking. In this study, therefore, the limiting factors of resources and the environment in the BTH region were assessed based on the framework of landscape sustainability science. First, we chose five limiting factors, including topographic condition, geological environment, water resource, land resource, and atmospheric environment, to assess the constraints of resources and the environment using the single-factor evaluation method and the multi-factor comprehensive evaluation method. Based on the results, we divided the whole region into five subregions, i.e., the ecological conservation subregion, the geological disaster subregion, the water resource scarcity subregion, the atmospheric pollution subregion, and the cropland protection subregion. The results revealed that the northern BTH region was highly constrained by topographic conditions, the central BTH region was strongly constrained by geological environment and water resources, whereas the southern BTH region was constrained mainly by land resources and atmospheric environment. In addition, water resource was the main limiting factor for regional population growth and economic development. In 2010, the water resource scarcity subregion had a total population of 39.59 million, an urban population of 76.90%, and a gross domestic product of 2 455.57 billion yuan. We argue that the sustainable development of the BTH region should explicitly consider the resource and environmental limiting factors, implement land use optimization according to local conditions, maintain multiple land use types and diverse management strategies, based on the perspective of “strong sustainability”, so as to promote the regional sustainable development.  相似文献

What happens when an Andean family finds gold on its land? As mining corporations rapidly claim surrounding properties on rugged terrain near Mount Mismi, a water-supplying deity overlooking Peru’s Colca Valley, the Flores family is springing into action to beat the Buenaventura mining company to the gold that might be hidden within. The global land rush has been pronounced in Peru, whose mineral resources have largely been responsible for rapid economic growth but whose profits remain restricted to a relative few. The Flores family, many of its members underemployed, are engaged in a costly race against time to constitute themselves as an enterprise, rent equipment, formalize their title, and fulfill other rituals necessary for legitimating their own effort to access what they see as their small share of Peru’s mineral wealth, against the specter of state subsoil rights and corporate power. They are simultaneously racing to seek the land’s permission, via rituals like the pago a la tierra (offering to the earth) and the provision of spiritually infused chicha (fermented maize and barley). Through an ethnographic focus on the exemplary case of the Flores property and the diverse rituals essential to extracting its prosperity, this article asks how the Peruvian state’s categories of legitimate land use articulate with a perspective acknowledging land as a powerful non-human agent with its own requirements for becoming investable. I argue that beyond a simple dichotomy between official and indigenous rituals of legitimation, the Flores’ urgent race to render land investable puts multivalent ontologies and ethics to work together. In doing so, I further argue, family members draw on years of engagement with development projects and non-governmental organizations focused on promoting explicitly indigenous entrepreneurship. They are thus forging new interpretations of identity-based empowerment that complicate any stereotypical relationship between environmental sustainability and indigeneity.  相似文献

In East Africa, financially strained governments increasingly experiment with voluntary, market-based carbon offset schemes for enhancing the public management of protected areas. Often, conservationists and governments portray these as ‘triple-win’ solutions for climate change mitigation, biodiversity preservation, and local socioeconomic development. Examining such rhetoric, this paper analyses the rise and decline of an integrated carbon offset and conservation initiative at Mount Elgon National Park in eastern Uganda, involving a partnership between the Uganda Wildlife Authority (UWA) and a Dutch NGO, Face the Future. In doing so, the paper reveals the ways in which the uncompensated dispossession of local residents was a necessary precondition for the project’s implementation. Although external auditors expected the project to sequester 3.73 million tons of carbon dioxide equivalent (tCO2e) between 1994 and 2034, conflicts forced the scheme to cease reforestation in 2003. Noting this rapid decline, we problematize the ways in which Face the Future and other carbon market intermediaries represented their activities via project documents and websites, obscuring the violence that was necessary for the project’s implementation. In so doing, we argue that the maintenance of a ‘triple win’ spectacle is itself integral to the management of carbon sequestration projects, as it provides consumers with a form of ‘ethical’ use value, and greatly enhances the capacity of carbon market brokers to accumulate exchange value by attracting ‘green’ investors. Consequently, what we term a ‘spectacular failure’ manifests in at least two ways: first, in the unravelling of the heavily mediatized spectacle of harmonious, profitable conservation, and, second, in the deleterious nature of the consequences that accrue to local communities and ecosystems alike.  相似文献

In this paper, we compare the elemental and isotopic (C, N, Pb) geochemistry of lake sediments from two contrasted environments in south‐central Chile. The first lake, Laguna Chica de San Pedro (LCSP), is situated in the urbanised area of the Biobio Region (36°S). The second lake, Lago Puyehue (40° S), is located 400 km to the southeast of LCSP and within an Andean national park. Our aim is to identify environmental impacts associated with increasing industrial activities and land degradation during the last 150 a. In LCSP, shifts in C/N atomic ratios, δ13C and δ15N from 1915–1937 to the late 1980s are attributed to successive land degradation episodes in the lake watershed. Based on a Pb isotopic mixing model, we estimate that up to 20% of lead in LCSP sediments is supplied from urban atmospheric pollution. By contrast, human impact in the watershed of Lago Puyehue is very limited. We observe no change in organic geochemistry during the last 150 a and lead contamination remains lower than 5%, even during the last decades. Although contamination levels are much higher in LCSP than in Lago Puyehue, a peak in anthropogenic Pb is recorded during the same period (1974–1976) at both sites. This maximum contamination level is consistent with increased industrial activity in the vicinity of Concepción. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

In this paper we outline the limitations of Environmental Justice theory when it comes to explaining and theorising the politics of contemporary environmental movements. Justice, we argue, needs to be understood not as a formalised and preconceived ‘thing’ to be delivered or applied but as an open egalitarian ideal that movements across the world continuously redefine in embodied and performed ways which are historically and geographically distinct. Drawing upon the fifteen year long anti-mining struggles of Rosia Montana, Romania, we explore the tension between seeking ‘traditional’ forms of justice (i.e. dialogic consensual politics) and putting forward more radical demands for socio-ecological change, in which representation and recognition are seen as insufficient practices for distributing justice. Visibility (rather than recognition) and egalitarian politics (rather than distribution) become the quilting points of struggles of many contemporary environmental movements, equality can only be enacted (or staged) through praxis that disrupts the distribution of the sensible experience and exposes the arbitrariness and incompleteness of power. We argue that in order to analyse and theorise the praxis of contemporary environmental movements, it is imperative for geographical literature to engage with post-foundational theory, and ‘un-do’ pre-conceived ideas and theorisations of (environmental) justice.  相似文献
