More than 50 years of research, development, manufacture, and testing of nuclear weapons at Department of Energy (DOE) sites
has left a legacy of on-site contamination that often spreads to surrounding areas. Despite substantial cleanup budgets in
the last decade, the DOE's top-to-bottom review team concluded that relatively little actual cleanup has been accomplished,
although milestones have been met and work packages completed. Rather than solely use regulatory constraints to direct cleanup,
many people have suggested that human and ecological health should guide long-term stewardship goals of DOE-managed sites.
The main questions are how ecological and human health considerations should be applied in deciding the extent of cleanup
that contaminated sites should receive and how near-term and longer run considerations of costs and benefits should be balanced
as cleanup decisions are made. One effort to protect ecological integrity is the designation of the largest sites as National
Environmental Research Parks (NERPs). Recently, the Competitive Enterprise Institute (CEI) suggested isolating and conserving
DOE sites as a policy priority because of their rich ecological diversity. A more effective long-term stewardship approach
for former nuclear weapons complex sites may emerge if the guiding principles are to (1) reduce risks to human and ecological
health, (2) protect cultural traditions, and (3) lower short- and long-term cleanup and remediation costs. A “net benefits”
perspective that takes both near- and longer-term costs and consequences into account can help illuminate the trade-offs between
expensive cleanup in the near term and the need to assure long-term protection of human health, cultural values, and high
levels of biodiversity and ecological integrity that currently exist at many DOE sites. 相似文献

生态补偿主客体研究是制定及实施生态补偿政策的核心要素之一。本研究从系统分析的角度出发,基于2014年洞庭湖主要入湖河流水质、水量情况,核算了主要入湖河流总氮、总磷通量,并结合2014年洞庭湖生态经济区污染物排放情况,详细分析了洞庭湖总氮、总磷的来源,以此为依据界定了洞庭湖水环境生态补偿的主体与客体。结果显示,洞庭湖水体中总氮、总磷的贡献以洞庭湖生态经济区之外地区,通过四水、三口排入洞庭湖为主。基于此,本研究建议洞庭湖水环境生态补偿的主体省级层面应为湖南省和湖北省,而省外层面则为国家作为补偿主体对洞庭湖生态经济区进行补偿。 相似文献

“放管服”背景下以环评为核心的环境准入体系面临工作周期长、制度效率低、结论可验证性差、社会认可度不高等诸多挑战。本文针对“三线一单”具有的早期介入和共享区域基础信息的工作特征,认为将“三线一单”纳入环境准入体系后可以更好地发挥系统性预防作用,提升政府的决策能力和环评工作效率,实现环境准入体系的高质量和高效率。在重构环境准入体系方面,提出了“三线一单”与规划环评和项目环评制度衔接的关键环节:明确三项制度不同的职责定位和责任主体、厘清三项制度的衔接环节,以及完善三项制度间的信息交互。 相似文献

Research was conducted in Nottinghamshire, England to investigate public attitudes regarding home energy efficiency issues. Quantitative data were collected in the form of a postal survey, achieving over three hundred responses. Additionally, predominantly qualitative data were collected in semi-structured interviews in 15 homes. The issues investigated included the grant-funded energy efficiency measures installed by the public, the organisations providing grants, the means by which the recipients were referred to the organisations, and the public's preferences regarding energy efficiency advice. Findings were made about the local authority's success in encouraging the take-up of energy efficiency grants, about the public's preferences for the means by which advice should be provided, about trust relating to energy efficiency grants provided by gas and electricity suppliers, and about people's knowledge of the most effective energy efficiency measures. Additional findings were drawn about specific energy efficiency issues, including old heating systems and compact fluorescent light bulbs. 相似文献

The fisheries of Lake Victoria have undergone a major transformation over the last three decades. The character of the lake has been subject to the influence of many powerful factors including: substantial increases in fishing effort; growing integration into the global fish market; acceleration of anthropogenic activities in the catchment area; demographic change; the influence of adverse shifts in the climate; and introduction of exotic plant and animal species. The task of managing the lake's resources, therefore, has never been more daunting. This article argues that, in most cases, the authorities charged with achieving the goal of sustainable development for the fishery, have failed to address the symptoms—let alone the origins—of the current unsustainable tendencies embedded in the social, economic and political fabric of Lake Victoria's riparian States. It is these factors that directly impinge upon the success of management initiatives for the lake. The article argues that if sustainable development is to be achieved, then stakeholders must act in concert, eliminate unsustainable practices and reprogramme development plans to focus on realistic goals. A possible way forward will be to develop a participatory management system. 相似文献
