Assessing the Institutional Effectiveness of State Environmental Agencies in Turkey

Improving the performance of the state environmental agencies (SEAs) necessitates an effective institutionalization of governmental environmental management functions. There are examples of successful and unsuccessful SEAs in several parts of the world. Analysis and assessment of these cases can deliver useful insights for institution builders. The objective of this article is the assessment of the institutional effectiveness of the SEAs in Turkey through the perceptions of the experts using the Delphi Technique. In this regard, a checklist is developed including 16 criteria and 123 subcriteria to measure the institutional effectiveness of the SEAs. Twenty-eight national and international experts have formed a Delphi panel and evaluated the national and local conditions. Results, based on the perceptions of the experts, indicate that the overall effectiveness of the SEAs is far less than satisfactory. Negative consensus has been reached over the effectiveness of 13 of the16 criteria and 95 of the123 subcriteria; however, no consensus has been achieved over the remainder of the parameters. The survey has also proven that the Delphi Technique can be effectively used for that purpose. Utilization of the checklist method is also useful in diagnosing the problematic components of the SEAs. It is recommended that this approach be used in similar cases elsewhere.

页岩气开发对生态环境影响评价模型

针对页岩气特殊的开发方式及环评难度比常规气大的特点,运用"压力-状态-响应"框架模型,建立了页岩气开发对生态环境影响的评价指标体系。引入曲线投影的方式,并将投影寻踪方法和动态聚类方法相结合,提出了曲线投影寻踪动态聚类的定量评价方法;基于样本各指标的曲线投影和动态聚类方法寻找最佳投影方向,并建立相应的生态环境影响评价优化模型。结合全局最优经验指导和信息素交流,采用改进的蚁群算法对优化模型进行求解。该算法维持蚁群的多样性,且收敛性较好,同时也避免出现局部最优。对四川省威远页岩气区块进行了实例分析,结果表明:2010年、2011年和2014年的环评属于差类(4级),2012年和2013年的环评属于中类(3级),其中植被覆盖率、空气质量优良率、地表水质达标率、废水排放量、公众对环境的满意度、二氧化硫排放量和废水排放量达标率等指标对生态环境评价的影响较大。在页岩气开发初期,由于开发技术落后,再加上环保投资不高,环保意识不强,造成生态环境问题较为严重。随着学习借鉴美国的经验,及页岩气的开发技术进一步提高,加上国家对生态环境保护的重视,威远页岩气区块生态环境恶化得到有效的遏制。但开发时间越长,开采难度越大,将会产生更多更大的生态环境问题。分析结果与威远页岩气开发区域的实际情况相符,为页岩气气田生态环境影响评价奠定了科学基础。投影寻踪动态聚类方法具有无需设定参数、操作简单、客观等优点,是页岩气开发对生态环境影响评价的一种新方法。     

仙女湖富营养化特征与水环境容量核算

以典型的亚热带大型水库——江西省仙女湖为例,于2011~2013年季节性监测了仙女湖水体理化指标。采用综合营养状态指数法对其富营养化状态进行了评价,并采用沃伦威德尔模型(Vollenweider)和狄龙模型(Dillon)计算了COD、NH₃-N、TN和TP的水环境容量。结果表明:仙女湖水质总体处于地表水Ⅱ类~Ⅲ类标准,TN 0.32~0.91 mg/L、平均0.59 mg/L,NH₃-N 0.012~0.59 mg/L、平均0.31 mg/L,TP 0.017~0.080 mg/L、平均0.028 mg/L,COD_Mn 1.61~5.59 mg/L、平均2.85 mg/L,Chl-a 0.37~0.95 μg/L、平均0.56 μg/L。从湖区上游到下游,各指标尤其是总氮、总磷、透明度和氨氮呈现明显的趋优变化特征,除TP出现Ⅲ类水质外,其余指标多年持续处于Ⅱ类水质状态;从单因子状态指数来看,采用透明度评价的营养状态最高,大部分湖区持续处于轻度富营养状态;TN和TP评价的营养状态次之,处于中营养水平。仙女湖COD、NH₃-N、TN和TP水环境容量分别为21 208.0、3 528.8、4 991.2和248.1 t/a,分别剩余容量比率56.88%、68.25%、62.89%和13.67%,影响仙女湖水环境容量最突出的环境因子为TP。同时,基于对水环境容量影响因素的分析,最后提出了提高仙女湖区水环境容量的建设性方案。     

论中国环境预警制度的法治化--以行政权力的规制为核心

环境预警制度蕴含了一项使行政权力合法扩张的"对应性架构",即预警级别与"强制型"或"限制型"措施之间的充分必要关系。在制度运行过程当中,环境行政权力却出现了"选择性失语"和"运动式肆意"的问题,具体表现为:一是预警级别发布时的"隐匿"与"从轻",从而对公民健康权益保护不足;二是预警状态下环境行政权力的扩张过度,使得对个人自由与企业经济自由侵害过度。由于环境治理领域"被害人-加害人"二元对立关系的模糊化、趋同化甚至同一化,传统公法学体系中的权力制约理论无法对预警状态下多样化和多层次性的行政权力进行有效地规制。那么,便有必要对现有的环境预警制度进行修正与纠偏。因此,可以从"对应性架构"的载体及其前后两端入手,对环境预警制度进行法治化建构。具体而言,对环境预警的载体"应急预案"进行形式改造,提高环境应急预案的规范层级,完善环境应急预案制定、修改等程序性规定;明确不同预警级别设定的规范层级,将作为被宪法所保护的客观利益——生态环境利益与经济利益的边界——通过"前端"预警标准予以划分;对预警状态下行政权力的"外部"制约程序予以完善。基于预警级别标准体系的划分,可以通过司法程序对"后端"环境应急预案进行"附带性审查",同时,赋予私主体直接针对预警状态下具有"外化"法效力的内部行政行为提起行政诉讼的诉权。     

庐山不同森林植被类型土壤碳库管理指数评价

土壤碳库管理指数(CPMI)是表征土壤碳库变化的一个重要量化指标,能够反映土壤的碳库变化和碳库质量。选取庐山8种森林植被类型土壤为研究对象,对其土壤有机碳库特征及碳库管理指数进行系统研究。结论表明:(1)土壤有机碳(SOC)主要分布于0~20 cm土层中,随着土层深度增加,不同森林植被类型下SOC含量急剧下降;在0~60 cm土层中,不同森林植被类型下SOC含量的平均值排序为:马尾松林常绿阔叶林灌丛针阔混交林常绿-落叶混交林黄山松林落叶阔叶林竹林。(2)不同森林植被类型下活性有机碳(ASOC)含量为0.24~0.57 g·kg–1,总有机碳(TOC)含量为9.72~14.74 g·kg–1,土壤碳库指数(CPI)为1.63~2.48,碳库活度(A)为0.019~0.062,碳库活度指数(AI)为0.388~1.265。不同森林植被类型下ASOC含量排序:落叶阔叶林黄山松林常绿-落叶阔叶混交林灌丛针阔混交林常绿阔叶林竹林马尾松林;不同森林植被类型下ASOC/TOC(%)排序:落叶阔叶林黄山松林常绿-落叶阔叶混交林竹林灌丛针阔混交林常绿阔叶林马尾松林;不同森林植被类型下CPMI排序为:落叶阔叶林黄山松林常绿-落叶阔叶混交林灌丛针阔混交林常绿阔叶林竹林马尾松林。     

A radical public administration? Green radicalism and policy influence among local environmental officials in Sweden

Green radicalism among local environmental officials in Sweden is examined with the aims of theoretically elaborating on different dimensions of Green radicalism in the context of public administration, exploring the dimensionality of Green radicalism among officials, and examining the extent to which Green radicalism is associated with policy influence. Three types of Green radicalism are identified: Green ethics, Green institutional change, and Green activism. Survey data (N = 701) show that the three theoretical dimensions are present among officials, and that there is no negative association between radicalism and influence. It is primarily officials with Green activism beliefs who perceive themselves as able to influence policy. These findings suggest a need for more nuanced understanding of and further studies into the role of public administration in the quest for more radical Green reforms.     

Simulative governance: on the collaborative narrative of civil society participation in the CDM stakeholder framework

The Kyoto Protocol’s Clean Development Mechanism (CDM) is often cited as an exemplar of new, hybrid forms of global environmental governance operating at the public–private interface. Practically, enacting this arrangement involves a wide range of non-state actors. This broad involvement is here assumed to mark a shift towards more polycentric and networked modes of governance in which agents collaborate as ‘stakeholders’ in the process of consensual rule-setting and implementation. Using post-political critique, the depoliticising effects of the stakeholder framework on civil society actors are interrogated, using formal and informal participation opportunities to raise concerns regarding specific CDM projects. The analysis suggests that the CDM’s collaborative narrative of stakeholding structurally fails to stimulate public (re)engagement and is, instead, a prime example of simulative governance that struggles to achieve the simultaneity of two incompatibilities: the participatory revolution and the post-political turn.     

Welfare states and environmental states: a comparative analysis

A framework is presented for thinking about state intervention in developed capitalist economies in two domains: social policy and environmental policy (and, within that, climate-change policy). Five drivers of welfare state development are identified, the ‘five Is’ of Industrialisation: Interests, Institutions, Ideas/Ideologies, and International Influences. Research applying this framework to the postwar development of welfare states in the OECD is summarised, distinguishing two periods: up to 1980, and from 1980 to 2008. How far this framework can contribute to understanding the rise and differential patterns of environmental governance and intervention across advanced capitalist states since 1970 is explored, before briefly comparing and contrasting the determinants of welfare states and environmental states, identifying common drivers in both domains and regime-specific drivers in each. The same framework is then applied to developments since 2008 and into the near future, sketching two potential configurations and speculating on the conditions for closer, more integrated ‘eco-welfare states’.     

环境分权、市场分割与碳排放

中国有着庞大的环境管理队伍以及巨大的国内市场,科学的环境管理制度以及高度一体化的国内市场将深刻改变碳排放格局,然而,已有研究对于这些影响碳排放的体制性因素既缺乏足够的理论分析也缺乏实证检验。有鉴于此,本文首先分析了环境分权和市场分割影响碳排放的理论机理,并提出了三个理论假设,进一步地,本文以环境管理人员在不同层级政府的配置衡量环境分权度,以相对价格法衡量市场分割程度,基于1995-2012年的省际面板数据,从实证层面检验了环境分权和市场分割对碳排放的影响效应。结果显示:环境分权和市场分割都显著地加剧了碳排放,原因在于分权的环境管理体制安排扭曲了激励,无法对碳排放形成真实有效的约束,而市场分割则恶化了碳排放在区域间的配置效率。同时,环境分权与市场分割对碳排放的共同影响作用上存在互补效应,即环境分权程度越高,市场分割对碳排放的负面影响效应越大,反之,市场分割程度越高,环境分权对碳排放的负面影响效应也越大。这主要是由于环境分权与市场分割是地方政府一对互补的策略行为,在环境分权较高的地区,地方政府进行市场分割的能力越强,而在市场分割较高的地区,地方政府争取环境事务管理权的动力越强。因此,在既定的碳排放约束下,中央政府一方面需要适度集中环境事务管理权限,进一步优化环境事务管理机构设置以及人员队伍在不同层级政府间的配置,提高对碳排放的管控效率,另一方面需要打通省际壁垒,加快区域市场一体化建设,优化碳排放的区域配置,提高碳排放效率。
