Threats to rural livelihoods and rural landscapes have increased over time as developed nations in particular look for cheaper and more locally based alternatives to traditional energy sources to drive national economies. In New South Wales, through the expansion of coal mines and coal seam gas (CSG), small towns such as Gloucester on the edge of the Upper Hunter are faced with competing visions which seek to redefine their future. Powerful and competing discourses over land use threaten not only the sustainability of the region but the integrity of its sense of place, centred on community, rurality, agricultural production and confrontation of risk from mining. The different discourses of local groups such as ‘tree-changers’, established residents and farmers conflict with those of external organisations such as the State government and mining/CSG companies which envisage Gloucester as a ‘balanced’ space of co-existence and position it as a new node in the carbon supply chain.  相似文献

Recent neo-liberal policy frameworks in Australia advocate economic development opportunities for Aboriginal Australians as a viable strategy to redress the marginalisation and social disadvantage that appear to characterise many Aboriginal communities. In New South Wales (NSW), Aboriginal peoples are currently negotiating with industry for the chance to participate in coal seam gas (CSG) development opportunities. Based upon research focusing on CSG development in the Northern NSW region, this paper argues that certain constructions of Aboriginality inhibit successful Aboriginal engagement with the economic opportunities provided by CSG. This paper illuminates the role of the media in facilitating dominant discourse about Aboriginality and the implications of those constructions for Aboriginal engagement with the mainstream economy. Findings demonstrate that the media are complicit in constructing Aboriginal peoples in a way that could prejudice their attempts to engage in economic opportunities that do not align with the dominant constructions of Aboriginality.  相似文献

区域规划环境评价的空间特性决定其对空间尺度的敏感性。本文从理论层面对区域规划环评中空间尺度与基础数据的关系、空间尺度与显著环境因子识别以及评价指标体系的关系、空间尺度与大气环境影响预测的关系进行了初步探讨。并以"上海高桥镇区域规划环境影响评价"(2005年)和"上海浦东新区国民经济与社会发展规划战略环境评价"(2010年)为例,通过对比方法,进一步说明空间尺度与显著环境因子识别和评价指标体系以及与环境影响预测的关系。结果表明:基础数据收集、汇总是区域规划环评中极为重要的环节,由于不同类型的基础数据表现出不同的空间特征,需要根据评价区域的实际和评价要求,合理选择数据所涵盖的空间范围和空间分辨率。区域规划环境评价应根据本身的层次、涉及范围,筛选出合理的显著环境因子,并建立相应的评价指标体系。大尺度上环境空气质量预测评价的结果侧重于总体描述、解释污染物散布的宏观空间格局和趋势,而在小尺度上则更有利于揭示局地精细化的污染扩散规律。  相似文献

Two widely-used techniques to estimate the volume of remaining oil and gas resources are discovery process modeling and geologic assessment. Both were used in a recent national assessment of oil and gas resources of the United States. Parallel estimates were obtained for 27 provinces. Geological-based estimates can typically see into areas not available to discovery process models (that is areas with little or no exploration history) and thus, on average, yield higher estimates. However, a linear relation does exist between the mean estimates obtained from these two methods. In addition, other variables were found in a multiple regression model that explained much of the difference. Thus, it is possible to perform discovery process modeling and adjust the estimates to yield results that might be expected from geological-based assessments.  相似文献

Anthropogenic greenhouse gases (GHG) emission and related global warming issues have been the focus of international communities for some time. The international communities have reached a consensus to reduce anthropogenic GHG emissions and restrain global warming. The quantitative assessment of anthropogenic GHG emissions is the scientific basis to find out the status of global GHG emission, identify the commitments of each country, and arrange the international efforts of GHG emission reduction. Currently the main assessment indicators for GHG emission include national indicator, per capita indicator, per GDP indicator, and international trade indicator etc. The introduction to the above indicators is put forward and their merits and demerits are analyzed. Based on the GHG emission data from the World Resource Institute (WRI), the US Energy Information Administration (EIA), and the Carbon Dioxide Information Analysis Center (CDIAC), the results of each indictor are calculated for the world, for the eight G8 industrialized countries (USA, UK, Canada, Japan, Germany, France, Italy and Russia), and the five major developing countries including China, Brazil, India, South Africa and Mexico. The paper points out that all these indicators have some limitations. The Indicator of Industrialized Accumulative Emission per Capita (IAEC) is put forward as the equitable indicator to evaluate the industrialized historical accumulative emission per capita of every country. IAEC indicator can reflect the economic achievement of GHG emission enjoyed by the current generations in every country and their commitments. The analysis of IAEC indicates that the historical accumulative emission per capita in industrialized countries such as UK and USA were typically higher than those of the world average and the developing countries. Emission indicator per capita per GDP, consumptive emission indicator and survival emission indicator are also put forward and discussed in the paper.  相似文献

The Eastern Kentucky coal field, along with adjacent portions of Virginia and southern West Virginia, is part of the greatest production concentration of high-heating-value, low-sulfur coal in the United States, accounting for over 27% of the 1993 U.S. production of coal of all ranks. Eastern Kentucky's production is spread among many coal beds but is particularly concentrated in a limited number of highquality coals, notably the Pond Creek coal bed and its correlatives, and the Fire Clay coal bed and its correlatives. Both coals are relatively low ash and low sulfur through the areas of the heaviest concentration of mining activity. We discuss production trends, resources, and the quality of in-place and clean coal for those and other major coals in the region.  相似文献

Latitudinal permafrost in Northern Northeast(NNE)China is located in the southern margin of the Eurasian continent,and is very sensitive to climatic and environmental change.Numerical simulations indicate that air temperature in the permafrost regions of Northeast China has been on the rise since the 1950s,and will keep rising in the 21st century,leading to extensive degradation of permafrost.Permafrost degradation in NNE China has its own characteristics,such as northward shifts in the shape of a"W"for the permafrost southern boundary(SLP),discontinuous permafrost degradation into islandlike frozen soil,and gradually disappearing island permafrost.Permafrost degradation leads to deterioration of the ecological environment in cold regions.As a result,the belt of larch forests dominated by Larix gmelinii has shifted northwards and wetland areas with symbiotic relationships with permafrost have decreased significantly.With rapid retreat and thinning of permafrost and vegetation change,the CO2 and CH4 flux increases with mean air temperature from continuous to sporadic permafrost areas as a result of activity of methanogen enhancement,positively feeding back to climate warming.This paper reviews the features of permafrost degradation,the effects of permafrost degradation on wetland and forest ecosystem structure and function,and greenhouse gas emissions on latitudinal permafrost in NNE China.We also put forward critical questions about the aforementioned effects,including:(1)establish long-term permafrost observation systems to evaluate the distribution of permafrost and SLP change,in order to study the feedback of permafrost to climate change;(2)carry out research about the effects of permafrost degradation on the wetland ecosystem and the response of Xing'an larch to global change,and predict ecosystem dynamics in permafrost degradation based on long-term field observation;(3)focus intensively on the dynamics of greenhouse gas flux in permafrost degradation of Northeast China and the feedback of greenhouse gas emissions to climate change;(4)quantitative studies on the permafrost carbon feedback and vegetation carbon feedback due to permafrost change to climate multi-impact and estimate the balance of C in permafrost regions in the future.  相似文献

Global environmental politics and policy are conventionally seen as the province of nation-states and international negotiations. However, there has been increasing attention devoted to the part that local places can play in the pursuit of (global) sustainable development. In this paper, I explore the role of local government in Australian greenhouse policy. A brief outline of the role of local government in environmental management is followed by a short history of greenhouse policy in Australia. From its initial marginal position, local government has begun to occupy a more prominent role in greenhouse policy development and implementation. The paper examines the processes that have led to this change, the development of local greenhouse and energy policies in Newcastle, New South Wales, and the initiation of the 'Cities for Climate Protection' program by the federal government. In conclusion, some thoughts on the problems and prospects of a local approach to the greenhouse issue are offered.  相似文献

Social issues are critical to the mining industry. This study investigates how social issues have been, and are being, assessed and managed within this industry through a case study of Northparkes Mines in central west New South Wales (NSW). The research involved 29 interviews with mining executives, environmental consultants and citizens of Parkes, plus a document analysis of four environmental impact statements prepared between 1990 and 2012. Where appropriate, findings were extrapolated to the wider mining industry. The standard for social impact assessment in NSW and emerging industry guidelines on social responsibility were analysed against internationally accepted good practice. Interviews indicated greater potential to recognise the social impacts of mining in NSW and identified good practice impact assessment as only one component of a successful community engagement strategy. Complementary strategies are essential to extend the benefits of development to local communities and for companies to establish a ‘social licence to operate’. The successful approach taken by Northparkes Mines combined good practice impact assessment with a localised workforce, an integrated management team and context-specific community engagement practices. This study highlights that local communities can be empowered through development, that benefits can extend to both the community and the business and that the ongoing management of social issues will increasingly be critical to the success of the mining industry.  相似文献

Research and development programs for improved productivity and profitability in horticulture have focused largely on understanding biophysical factors and production and harvest technologies. By contrast, relatively few studies focus upon the existing status of a rural community in terms of demographics, rationales and motivations underlying current farm management practices. Understanding such factors is increasingly important as pressures from climate change, globalised market forces, land-use competition and ageing workforces intersect on farms and for farmers. This paper explores experiences among macadamia growers in the Northern Rivers region of New South Wales, Australia, with the aim to better understand and improve the targeting of development programs to meet grower needs and aspirations, for improved industry resilience. Results suggest that growers are a diverse, ageing demographic who came into the industry with a variety of skill sets. Noting a lack of previous farming experience for many growers, we highlight the need to consider information transfer and succession planning, along with aspirations to consolidate properties and skills. New engagement approaches are recommended, with tailored extension to different grower groups. To aid with this process, a classification tree was developed for the purposes of separating growers into groups with different support needs.  相似文献

近年来,特别是2008年全球金融危机爆发以后,中国出口导向型制造业出现了由以出口为主转向出口和内销并进的发展趋势。然而现有文献较少关注市场转向对制造业企业产业升级的影响。基于全球生产网络的视角,以珠江三角洲出口导向型家具产业为例,通过以深度访谈为主的定性研究方法,探讨出口导向型制造业企业在出口转内销过程中的产业升级路径。结果显示:在与中国国内市场进行战略耦合(strategic coupling)的过程中,家具制造业企业分别通过网络式、企业内部协调式及市场型方式嵌入国内市场导向型的生产网络,并呈现出产业升级(upgrading)和降级(downgrading)等多元化路径。中国市场为家具制造业企业提供了产业升级特别是功能升级的机会,但小部分制造业企业也经历着产品降级的过程。研究市场转向中的产业升级对理解后危机时代新兴市场的崛起具有一定的理论意义;同时对理解在全球经济背景下中国出口导向型加工制造业转型具有实践意义。  相似文献

Geographic information systems (GIS) are increasingly being used in environmental impact assessments (EIA) because GIS is useful for analysing spatial impacts of various development scenarios. Spatially representing these impacts provides another tool for landscape ecology in environmental and geographical investigations by facilitating analysis of the effects of landscape pattern on ecological processes and examining change over time. Landscape ecological principles are applied in this study to a hypothetical geothermal development project on the Island of Hawaii. Some common landscape pattern metrics were used to analyse dispersed versus condensed development scenarios and their effect on landscape pattern. Indices of fragmentation and patch shape did not appreciably change with additional development. The amount of forest to open edge, however, greatly increased with the dispersed development scenario. In addition, landscape metrics showed that a human disturbance had a greater simplifying effect on patch shape and also increased fragmentation than a natural disturbance. The use of these landscape pattern metrics can advance the methodology of applying GIS to EIA.  相似文献

Hydraulic conductivities of fractured sandstone bore cores of 0.1 m in diameter are calculated using detailed characterization of the fracture geometry parameters determined using a resin casting technique. The accuracy of the measurements was about  0.25–1.25 μm  with the image size used. The values of the effective fracture apertures vary between 10 μm and 50 μm. For modelling purposes the samples are sectioned serially, perpendicular to the flow direction along the cylinder axis. The hydraulic conductivity of individual slices is estimated by summing the contribution of the matrix (assumed uniform) and each fracture (depending on its length and aperture). Finally, the hydraulic conductivity of the bulk sample is estimated by a harmonic average in series along the flow path. Results of this geometrical upscaling compare favourably with actual conductivity measured in hydraulic and pneumatic experiments carried out prior to sectioning. This study shows that the determination of larger-scale conductivity can be achieved, based on the evaluation of fracture geometry parameters (e.g. fracture aperture, fracture width and fracture length), measured using an optical method, at least at the laboratory scale.  相似文献

Regional environmental evaluation often requires a large amount of spatial information. Remote sensing (RS) and geographic information systems (GIS) are capable of managing large amounts of spatially related datum, and providing the ability to integrate multiple layers and to derive additional information. A methodological reference framework, using RS, GIS, and AHP (the analytic hierarchy process), is developed for environmental vulnerability assessment. Using this proposed method, we carried out a case study in the Tibetan Plateau. An environmental vulnerability index (EVI) proposed incorporates 15 factors covering natural conditions, environmental issues, and human activities. According to the EVI values, the vulnerability was classified into five levels: slight (EVI<2.2), light (2.2EVI<2.7), moderate (2.7EVI<3.0), heavy (3.0EVI3.4), and extreme vulnerability (>3.4). The case study showed that the majority of the area in the Tibetan Plateau is ecologically lightly (light level; 22% of the total area), moderately (moderate level; 27%), and heavily (heavy level; 30%) vulnerable. Except for a clearly horizontal distribution, the environmental vulnerability increased clearly with increasing elevation (vertical distribution). The case study verified the usefulness and feasibility of the methods developed, for the results gained reflect the reality of the Tibetan environment closely. Further use in other regions should pay attention to what factors seem to be important in determining the local environmental vulnerability, and how is the impact of each factor on the complex environment.  相似文献
