区域大气环境质量管理的合作机制与政策讨论

区域环境管理与合作有助于从区域的角度出发解决由于跨界污染引发的利益冲突和纠纷;同时由于有效的区域管理和合作有可能基于区域间污染治理成本的差异,制定最小成本的污染防治战略,可以因此推动整个区域的协调发展。2010年以来,中国大气污染防治已经开始向区域管理转化,并开始步入跨地区合作的新阶段。但这种转型,尚缺乏有效的制度安排和政策手段的支撑。已有的区域环境管理合作实践所存在的诸多不足和障碍主要源于缺乏不同主体进行有效合作的激励机制,一方面由于各地区所处的经济发展阶段、地方环境保护意识等方面存在差异,往往很难促成真正的整合管理与合作;另一方面体现在相应的责任-利益协调机制缺失,致使跨地区合作难以常规化和长效化。因此,构建合理的区域大气环境管理与合作机制至关重要。本文分析和讨论了区域环境管理与合作中的关键问题,并在此基础上提出构建区域环境管理与合作机制的几点思考。     

Air Quality Management in UK Local Authorities: Public Understanding and Participation

Science and technology are an integral part of informing public policy on air pollution and transport management. Expectations of science and technology by society and their use by air quality policy makers has led to increasing reliance upon this evidence to promote health and well-being. This can be seen, for example, in the setting of the UK national objectives for air pollutants based on exposure and health effects. This paper addresses three questions. It assesses, through the use of focus groups, the public perceptions of air pollution and the atmospheric dispersion model output from the Atmospheric Dispersion Modelling System-Urban. Then it assesses their understanding of this information and its current presentation to the layperson. Finally, it assesses how their perceptions and understanding influence their solutions to local air quality management in the London Borough of Camden. The results show that participants in the study struggled with the concept of air pollution outside their sphere of experience, and they did not understand the scientific basis or modelling used to inform local policy. This is partly a result of the way this information is presented. They did not relate the technological evidence to their opinions of acceptable solutions or they expressed reluctance to suggest specific options. It is proposed that a well-informed public would make comprehensive decisions on air quality based upon a broader range of factors, incorporating the scientific reasoning and technological information as well as emotive and socio-economic factors. A balance between science and technological understanding with the validity of local expertise will improve air quality policy making to the greater satisfaction of all stakeholders.     

A longitudinal study of the links between Local Air Quality Management and Local Transport Planning policy processes in England

The second round of the Local Transport Plan (LTP2) process in England presents unique challenges and opportunities for integrating Local Air Quality Management (LAQM) within current transport planning policy. Using content analysis of LTP2 documents from nine English authorities, and results from a questionnaire survey of local government officers undertaken in late 2007, this paper charts the changes in the integration of air quality management within the transport planning process since 1997. While substantial improvements in policy integration were observed within the selected case studies, the paper demonstrates that such improvements are often constrained by institutional complexities that create implementation gaps between national objectives and local decision-making outcomes.     

Development and Implementation of Strategic Frameworks for Air Quality Management in the UK and the European Community

The UK and the EC have recognized that the application of national and EC policies alone may not be cost effective in improving air quality in some areas, especially in traffic-congested urban centres and along major road transport corridors. Consequently both have introduced new strategic frameworksfor air quality management.This paper outlines and compares the UK National Air Quality Strategy (NAQS) and the EC approach, set out in the Air Quality Framework and Daughter Directives. Both frameworks shift responsibility for reviewing, assessing and managing air quality on to local authorities. The UK considers the NAQS will provide the principal means of carrying out its commitments under the new EC framework.Local authorities in the UK have begun the review and assessment phase of the NAQS. This paper examines the support that central government has had to provide to local authorities to ensure the NAQS will be effective. It offers insights into what other Member States are likely to face when implementing their interpretation of the EC air quality management framework. The paper highlights that many UK local authorities lacked even basic air quality management capabilities when the NAQS was being formulated. Consequently the UK Government has had to expand the national pollution monitoring networks (this was achieved primarily by affiliating the growing number of local authority funded sites), commission new detailed urban emissions inventories, and develop and validate a suite of air quality dispersion models. Training events in air quality assessment techniques have had to be offered and many detailed guidance notes issued to ensure an appropriate and consistent interpretation of the NAQS. Some government initiatives to support the implementation of the NAQS suffered delays which initially caused some unnecessary uncertainties and inconsistencies amongst local authorities conducting their review and assessment of air quality. This points to the importance of the Governmentensuring that the support for the management phase of the NAQS will be in place in time. This includes providing additional pollution-control powers and reformulating transport and planning policies in order to integrate air quality management more fully.     

Proactive Management of Air Quality

Traditional air resource management systems have difficulty in addressing global issues, sustainable development, direct citizen participation, and integration with broad economic interests. As reactive management systems, they tend to be compliance-driven, static, and rigid. In contrast, proactive management systems are principle-driven, innovative, and flexible. Bridge scientists play a key role in supporting the transformation of raw data into wise action. Decision-makers need to integrate social values with knowledge about emissions, atmospheric processes, and potential environmental effects using the primary tools of measurements, monitoring, and modeling. The Alberta Clean Air Strategic Alliance, a unique partnership of governments, industry, and public interest groups formed in 1994, operates a comprehensive air management system that is capable of addressing air issues of greater complexity and uncertainty. Its success is measured by the satisfaction of its diverse stakeholders and by the number and scope of its initiatives.     

Carbon in the Vegetation and Soils of Great Britain

•The total amount of carbon held by vegetation in Great Britain is estimated to be 114 Mtonnes. •Woodlands and forests hold 80% of the G.B. total although they occupy only about 11% of the rural land area. Broadleaf species hold about 50% of the carbon in woodlands and forests. •A map of carbon in the vegetation of Great Britain at 1 km×1 km resolution based on land cover identified in the I.T.E. Land Cover Map is presented. The predominant location of vegetation carbon is the broadleaved woodlands of southern England. •The amount of carbon in the soils of Great Britain is estimated to be 9838 Mt (6948 Mt in Scotland and 2890 Mt in England and Wales). •In Scotland, most soil carbon is in blanket peats, whereas most soil carbon is in stagnogley soils in England and Wales. •The carbon content of the soils of Great Britain is mapped at 1 km×1 km resolution. Scottish peat soils have the greatest density of carbon and in total contain 4523 Mt of carbon, 46% of the G.B. total.

Estimating the extent and change in Broad Habitats in Great Britain

A stratified random sample of kilometre squares in Great Britain was visited and completely mapped using four areal themes (agriculture and semi-natural vegetation, forestry, physiography and buildings and communications). The maps were digitised and the attribute information recorded to produce an electronic database. Information was summarised by square and then bootstrap re-sampling techniques were used to produce national estimates with statistical confidence intervals. The results for 1998 showed the terrestrial Broad Habitats had a range in extent covering two orders of magnitude from Montane (49000ha) to Improved Grassland (5482000ha). Just under half of Britain is covered by agricultural Broad Habitats, about 12% by woodland and just under 10% by Urban Habitats. The remaining quarter of the land area is covered by semi-natural Broad Habitats. By revisiting the same sample of squares previously visited in 1990, changes in the quantity and quality of the Broad Habitats have been determined. Significant increases in area have occurred in the Broadleaved, Mixed and Yew Woodland and Built Up and Gardens. The largest areal reduction was in Acid Grassland although that was in part balanced by a gain in Fen, Marsh and Swamp. The most significant ecological loss was in the area of Calcareous Grassland. The consequences of having different sample sizes for the different years are discussed.     

Enhancing consultation practices on Air Quality Management in local authorities

Schedule 11 of the Environment Act 1995 underpins the requirement for consultation on air quality issues. The ongoing air quality review and assessment process represents one of the largest locally based science policy and communication initiatives ever undertaken in the UK. This paper outlines the practice of consultation and communication for Air Quality Management (AQM) and reviews the interaction between Environmental Health professionals, as the leading actor in the AQM process and other stakeholders involved in air quality consultation, including the public. Results are presented from a widespread questionnaire survey of English local authorities. Data indicate that the majority of air quality consultation has been carried out with statutory consultees (by sending the review and assessment reports) and the public (via websites and leaflets) in the form of information dissemination.

Local and Regional Partnerships in Natural Resource Management: The Challenge of Bridging Institutional Levels

Although collaboration and multi-stakeholder partnerships have become a common feature in natural resource management throughout the world, various problems are associated with attempts to up-scale community-based natural resource management from the local to the regional level. To analyze the reasons behind these problems, this article reports on two examples of collaboratives in Australia: local Landcare groups, and regional natural resource management (NRM) bodies. Recent government-induced changes have shifted the focus from local Landcare group action to strategic planning and implementation by regional NRM bodies. Two typologies of collaboratives are applied to analyze the characteristics of both these groups. The study uses data from 52 qualitative interviews with key informants at the local and regional level in Victoria and Tasmania, participant observation, as well as literature and document analysis. The article illustrates how the groups’ distinct characteristics can cause conflicts when the different types of collaboratives operate in parallel. In addition, the article reports how stakeholders perceive the level of community participation in decision-making processes. The key message is that the benefits of community participation and collaboration that arise at the local level can be lost when these approaches are up-scaled to the regional level unless there is an intermediary or ‘mediating structure’ to facilitate communication and create the link between different types of collaboratives.     

An Integrated Framework for Multipollutant Air Quality Management and Its Application in Georgia

Air protection agencies in the United States increasingly confront non-attainment of air quality standards for multiple pollutants sharing interrelated emission origins. Traditional approaches to attainment planning face important limitations that are magnified in the multipollutant context. Recognizing those limitations, the Georgia Environmental Protection Division has adopted an integrated framework to address ozone, fine particulate matter, and regional haze in the state. Rather than applying atmospheric modeling merely as a final check of an overall strategy, photochemical sensitivity analysis is conducted upfront to compare the effectiveness of controlling various precursor emission species and source regions. Emerging software enables the modeling of health benefits and associated economic valuations resulting from air pollution control. Photochemical sensitivity and health benefits analyses, applied together with traditional cost and feasibility assessments, provide a more comprehensive characterization of the implications of various control options. The fuller characterization both informs the selection of control options and facilitates the communication of impacts to affected stakeholders and the public. Although the integrated framework represents a clear improvement over previous attainment-planning efforts, key remaining shortcomings are also discussed.     

柳州市2009-2014年空气污染变化

近年来,城市空气污染日益严重,已成为公众广泛关注的环境问题之一。柳州是中国西部的工业重镇、广西有名的工业城市,位列国家划定的113个大气污染防治重点城市之中,是广西第一个开展PM2.5监测的城市。本研究于2009—2014年连续6年对柳州市大气主要污染物SO2、NO2、PM10和PM2.5的浓度进行在线观测,获得了污染物的长期时间和空间分布特征。结果显示,SO2浓度呈逐年下降趋势,并于2011年达标之后显著下降,2014年相比2009年下降了50.0%;NO2浓度一直在低于标准以下波动(24.6~35.1μg/m3);PM10浓度呈逐年增长趋势,并从2011年开始超标,2014年相对于2009年增长了69.3%。各污染物浓度都具有显著的季节变化:冬季秋季春季夏季。SO2、NO2、PM10和PM2.5的浓度冬季相比夏季分别提高82.9%、56.3%、66.9%和133.6%。冬季SO2和秋冬季PM10超标,PM2.5除7月外全线超标。PM2.5/PM10的比值冬季也高于夏季,表明冬季更易富集细颗粒。各污染物浓度也表现出不同的空间分布。九中各污染物的浓度都最高,可能与其离柳州钢铁公司距离较近有关。SO2除九中外,其他站点均达标。NO2全部达标。PM10市监测站和九中超标。PM2.5所有站点超标严重。本研究结果表明,柳州市煤烟型污染得到有效控制,但颗粒物污染,尤其是细颗粒物污染日益严重。     

Air Quality Management: Participatory Ranking of Control Measures and Conflict Analysis

The ranking of air quality control measures according to a number of evaluation criteria and with the participation of a large number of interested publics is demonstrated. A pilot study for the South Coast Air Quality Management District of California serves as the reference point. Several methodological considerations are addressed, such as: (a) the enhancement of criterion priorities to account for the variability among the performance of the control measures when incommensurable impact levels are applied: (b) the derivation of alternative rankings according to the priorities of potential coalitions; (c) the assessment of the potential acceptability of a collective ranking given the degree of solidarity among participants with similar interest affiliations; and (b) the assessment of the extent to which the performance of specific control measures may override priority differences and lead to insignificant ranking differences.     

Local Government and Emerging Models of Participation in the Local Agenda 21 Process

Local Agenda 21, with its major emphasis on local accountability and democratization, challenges perceptions of local governance and offers a long overdue opportunity, for local authorities in particular, to develop broad-based, effective, participatory structures. This paper examines initial responses to this opportunity. It models the newly emerging participatory structures and processes in selected English local authority areas, and demonstrates that there may be no one path that local authorities should follow. A number of alternative approaches to community participation can and are being adopted, contingent upon local circumstances.     

Rendering reform: local authority planners and perceptions of public participation in Great Britain

Public participation in planning is frequently linked to ideas of environmental justice and sustainability; yet, despite the voluminous literature on the topic, the reaction of frontline planning professionals to the broadly pro-participation agendas of central and devolved government in Great Britain has not been sufficiently examined. This is important because of their role in implementing such agendas, and the space for frontline professionals to shape the contours of reform. Drawing on extensive empirical material, I explore the reaction of local authority planners to participation policies, finding divided opinion as to whether more participation is needed to improve planning, but a strong framing of participation as something requiring careful management. I conclude that planners are broadly supportive of participation so long as they are in control, which can be understood through an institutionalist perspective that suggests there will be a similar reaction to further, ongoing, efforts to make planning more participatory.
