海南岛近岸海域环境容量与纳污总量分析

通过对海南岛"十二五"期间近岸海域纳污总量、环境质量状况及环境容量比较分析,得出各主要排污区环境容量的剩余环境容量。结果表明,全省主要污染物化学需氧量入海量仅占环境容量的2.6%,氨氮占环境容量的26.6%,虽然全省近岸海域环境基本未受污染物入海量影响,仍有较大的纳污空间,可利用的环境容量非常充裕。为避免出现排污达标但环境质量下降的状况,提出建立近岸海域主要污染物总量控制制度,由浓度控制到总量和浓度控制并存。     

Reasons for implementing ISO 14001 in Malaysia

Environmental management systems (EMS) have been introduced globally to reduce environmental degradation issues brought about by industrial development. The research discussed in this paper is aimed at identifying the benefits and motivations of the implementation of EMS in compliance with the International Organization for Standardization (ISO) 14001 standard in Malaysian industries by using the pairwise comparison method. Experts in EMS from the Scientific and Industrial Research Institute of Malaysia were invited to participate in the research panel. Based on the experts’ input, data analysis was carried out by using multi‐criteria pairwise comparisons. The findings showed the ranked benefits and motivations of the implementation of the ISO 14001 standard for businesses. The results can indicate to policy‐makers and business advisors how businesses can be encouraged to implement the ISO 14001.     

Power,responsibility and justice: a review of local stakeholder participation in European flood risk management

Over the past few decades, there has been an increasing interest in the active involvement of local stakeholders in the management of floods in Europe. Such involvement is seen as necessary as the management of floods becomes more complex. Management approaches now seek to include a range of potential measures to reduce risk (e.g. structural defence, spatial planning and property-level protection measures). Local stakeholder involvement is seen to be important because governments lack the capacities such as knowledge and funding required to deliver all these measures alone. This paper focuses on the implications that more participative approaches have on the fairness of European flood risk management (FRM). Studies of environmental justice are well placed to address this question because they are interested in who is included and excluded from decisions related to the distribution of environmental goods (resources) and bads (risks). Existing literature suggests that fair decision-making processes (procedural justice) can lead to fair distribution or resources and risks (distributive justice). This literature review of 30 peer-reviewed papers provides an analysis of justice and FRM by assessing practices of participation which are presented in the recent literature on local stakeholder involvement in FRM in England, Germany and the Netherlands. It was found that participation in practice generally focuses on transferring responsibility to the local level at the expense of power. This paper discusses the implications that this finding has for justice and synthesises potential ways forward based on recommendations of the reviewed literature.     

“We can keep the fire burning”: building action competence through environmental justice education in Uganda and Germany

The global dimensions of climate change necessitate a response that takes national differences – social, economic, geographic, and cultural – into account. Action-oriented education has a key role to play in advancing citizen engagement in a culture of sustainability. This paper describes research conducted with one such education programme, Youth Leading Environmental Change (YLEC), which operates in six countries and engages university-aged youth in discussion and practice related to global sustainability, systems thinking, and environmental justice. YLEC aims to advance four key competencies; this paper focuses on the goal of action competence, which involves acquiring knowledge, reflecting on experience in the context of one’s values, envisioning alternative futures, and acting individually and collectively to advance those alternatives. The present article examines the impacts of YLEC on environmental action competence in two of the countries involved in this research: Uganda and Germany. In-depth interviews were conducted with participants in both countries to examine the development of action competence during and after the programme. Findings suggest that outcomes differed in each country, reflective of participants’ different lived experiences. YLEC effectively built on the conditions faced in each country to accompany youth to a higher level of awareness and action. These findings have implications for environmental education programmes striving to work with multiple nations and diverse participants.     

Spatial variance and assessment of nitrogen dioxide pollution in major cities of Pakistan along N5-Highway

This paper discusses the findings of the first car MAX-DOAS (multi-axis differential optical absorption spectroscopy) field campaign (300 km long) along the National Highway-05 (N5-Highway) of Pakistan conducted on 13 and 14 November, 2012. The main objective of the field campaign was to assess the spatial distribution of tropospheric nitrogen dioxide (NO₂) columns and corresponding concentrations along the N5-Highway from Islamabad to Lahore. Source identification of NO₂ revealed that the concentrations were higher within major cities along the highway. The highest NO₂ vertical column densities (NO₂ VCDs) were found around two major cities of Rawalpindi and Lahore. This study also presents a comparison of NO₂ VCDs measured by the ozone monitoring instrument (OMI) and car MAX-DOAS observations. The comparison revealed similar spatial distribution of the NO₂ columns with both car MAX-DOAS and satellite observations, but the car MAX-DOAS observations show much more spatial details. Maximum NO₂ VCD retrieved from car MAX-DOAS observations was up to an order of magnitude larger than the OMI observations in urban areas.     

人口统计学变量对环境保护公众参与意识的影响实证研究

采用问卷调查和数理统计等研究方法,研究了人口统计学变量在环境保护公众参与意识上的差异,以及与环境保护公众参与各个变量之间的相关性。结果表明:居民的年龄在公众环保行为和环保政策满意度上呈现显著性差异,居民的职业在环境保护认知、公众环保行为环保政策满意度上呈现显著性差异,居民的受教育程度在环境保护认知、个人环保习惯、公众环保行为、环保政策满意度上呈现显著性差异。婚姻状况与公众环保行为、环保政策满意度之间存在显著性负相关,年龄与环境保护认知之间存在显著性正相关,与环境政策满意度、环境表现满意度之间出现显著性的负相关性,职业与环境保护认知、个人环保习惯、公众环保行为之间存在显著性正相关性,与环保政策满意度、环保表现满意度之间存在显著性负相关。     

我国地下水环境管理现状及管理制度构建研究

在目前进行我国《水污染防治法》的修法工作中,发现地下水的相关责任由国务院多个部门负责,系统性差,协调难度大,存在工作性质与管理责任脱节的现象。因此,文章在总结梳理国内法律法规和相关管理规定及理清各部门管理责任的基础上,针对我国地下水的实际情况,提出完善我国地下水管理制度及建议。     

生态健康、生态风险、生态安全概念辨析

在人类活动影响下,生态系统退化的速度越来越快,作为衡量生态系统存在状态的生态健康、生态风险、生态安全评价日益受到重视。然而,目前对于3个概念的界定不够明晰,在评价过程中指标体系混淆混用,致使理论研究也固步不前,影响了对实践的指导意义。生态健康、生态风险、生态安全的联系体现在评价主体的一致性和生态安全评价需要以生态健康评价、生态风险评价为基础;而三者的区别体现在内涵、评价对象以及评价的指标体系3个方面。     

入世十年我国对外贸易的宏观环境影响研究

入世十年来,我国对外贸易迅猛发展,贸易价值量取得巨大顺差,但其背后却孕育着巨大的资源环境逆差。本文通过建立贸易的环境核算方法,运用我国"能源-经济-环境"投入-产出及CGE模型分析了2002、2005、2007年的投入产出表,对进出口产品虚拟污染物进行定量核算,衡量入世十年我国对外贸易的宏观环境影响。研究表明,入世十年来,我国净出口产品虚拟SO2排放约占全国排放总量的1/4;净出口产品虚拟CO2排放占全国排放总量超过30%;净出口产品COD排放占全国排放总量的20%以上。在不采取其他措施的情况下,我国在未来20年仍将处于巨大的贸易环境逆差之中。
