Domestic energy practices are a topical policy issue, with implications for climate change, energy security and fuel poverty. Accordingly, a growing body of literature examines ways of promoting energy conservation and generation by individuals. However, there has been relatively little discussion of how status and stigma are implicated in these practices, and may act as facilitators or barriers to “behaviour change”. To help address this gap, this article draws both on existing literature and a new UK-based study of people who are attempting to live sustainable lives, to provide insights into how domestic energy practices may be status-enhancing or stigmatising, and how these risks and opportunities can be managed. While energy practices are often understood as “inconspicuous”, it is argued here that in some circumstances individuals may actively manage the visibility of their energy practices. The discussion considers these findings with regard to social power relations, and identifies issues warranting further exploration within the emerging research agenda on energy and equity. 相似文献

从经济学角度看,自然遗产保护中必然涉及产权问题,建立合理的自然遗产产权制度是自然遗产保护的关键。我国目前的自然遗产产权制度暴露出许多弊端,如所有权基础上的自然遗产管理混乱,自然遗产经营权配置不合理,以及欠缺对自然遗产相邻权的规定等。这些产权制度方面暴露的问题,对于自然遗产的保护无疑是不利的。通过对自然遗产保护中产权问题的探析和国外在自然遗产保护方面经验的借鉴,对我国自然遗产保护产权权利束中的所有权、经营权和相邻权的完善提出了几点建议。 相似文献

This article uses experiences from South Africa to argue that, despite progress made in making biodiversity conservation compatible with social, political and economic changes, progress could still be limited by reluctance of social actors to acknowledge and engage with the issue of race. The article argues that acknowledging the history of conservation in Africa, including close ties to racially charged colonialism, could be a positive impetus in the transformation of conservation to make it more socially, economically and politically justifiable. 相似文献

This study presents the contributions of materials, earth engineering machines and construction techniques to potential environmental impacts from the main items of typical road earthworks. To achieve this goal, the overall activity at a 1.9-km long French earthworks project site for a heavily trafficked highway was surveyed during its 2007–2009 construction period. Using data collected and a numerical model of road life cycle assessment (LCA), i.e. ECORCE, six indicators could be evaluated, namely: energy consumption, global warming potential, acidification, eutrophication, photochemical ozone creation, and human chronic toxicity. When available, several life cycle inventories were implemented in order to appraise indicator sensitivity with respect to the considered panel of pollutants. Results also allowed estimating from an LCA point of view: (i) the conservation of both aggregates and soil as induced by quicklime treatment and (ii) the duration necessary for projected traffic levels to offset the potential environmental impacts of the earthworks stage. 相似文献

环境温度是研究车用压缩天然气瓶火烧试验机理的一个重要因素,因此有必要定量的研究环境温度对火烧试验的影响。在已有火烧试验数据的基础上,分析了环境温度对车用压缩天然气瓶火烧试验安全泄放压力和火烧持续时间两个关键指标的影响,结果表明安全泄放压力、火烧持续时间和环境温度均呈反比关系。 相似文献

A bacterium classified as Achromobacter xylosoxidans strain IR08 by phenotypic typing coupled with 16S rRNA gene analysis was isolated from a soil contaminated with electrical transformer ?uid for over sixty years using Aroclor 1221 as an enrichment substrate. The substrate utilization profiles revealed that IR08 could grow on all three monochlorobiphenyls (CBs), 2,4'- and 4,4'-dichlorobiphenyl as well as 2-chlorobenzoate (2-CBA), 3-CBA, 4-CBA, and 2,3-dichlorobenzoate. Unusually, growth was poorly sustaine... 相似文献

This paper recommends a revision of watershed development policy in India in relation to the planning of development interventions
involving agricultural intensification and rainwater harvesting following biophysical and societal impact studies carried
out on two watershed development projects in Karnataka. A need for changes in policy has arisen in response to progressive
catchments closure at the basin level and declining volumes of water flowing into village level reservoirs (known locally
as tanks). Flow reductions have occurred largely as a result of increased agricultural intensification over the past 10–15 years.
Field levelling, field bund construction, soil water conservation measures, farm ponds, the increase in areas under horticulture
and forestry and the increased abstraction and use of groundwater for irrigation are all contributing factors to reduced flows.
Planning methodologies and approaches, which may have been appropriate 20 years ago for planning water harvesting within watershed
development projects, are no longer appropriate today. New planning approaches are required which (1) take account of these
changed flow conditions and (2) are also able to take account of externalities, which occur when actions of some affect the
livelihoods of others who have no control or influence over such activities and which (3) contribute to the maintenance of
agreed minimum downstream flows for environmental and other purposes.
