Development of environmental policy,objectives, and targets

This paper describes a process to develop and establish an environmental policy and its associated environmental targets, objectives, and management programmes. The environmental policy is defined in a statement which addresses the company expectations for programmes that are important to assure adequate environmental protection and define its future commitment towards preventing pollution and continuously improving the effectiveness of its environmental protection programmes. A set of environmental objectives, derived from the policy, define the overall goals which will ensure that the company's environmental performance will remain consistent with the commitment identified in its policy when its environmental management system (EMS) is implemented, Environmental targets reflect the requirements and standards that the company must strive to achieve each objective and minimize any harmful environmental impacts from its production and manufacturing processes or other activities. In addition to defining specific targets, environmental management programmes are also used to guide EMS implementation. These programmes, however, must provide the company with the necessary flexibility to select the most appropriate technologies to enhance its own processes and prudently allocate its available financial resources in areas that return the greatest overall environmental benefit.Though they are expected to allow some discretion in the allocation of resources targeted towards environmental protection, EMS programmes must also provide assurance that the corporation environmental policy, objectives, targets, and management programmes do not result in a facility failure to adhere to all of its certification requirements. The principle and factors described in this article should be considered to the extent that they are necessary and practical.     

洞庭湖区生态环境退化状况及其原因分析

洞庭湖居湖南省东北隅,长江荆江段南岸。湖泊形状呈近似“U”字形,岳阳站水位33.50 m时(黄海基面),湖长143.00 km,最大湖宽30.00 km,平均湖宽17.01 km,湖泊面积2625 km2;最大水深23.5 m,平均水深6.39 m,蓄水量167?08 m3。因入湖泥沙长期淤积、高洲围垦、并垸合流等自然因素和人类活动的共同影响,自清代末期以来,湖泊形态演变剧烈,湖盆抬高,入湖河流三角洲快速发育,湖面南移而缩小;现湖体已明显演变为西洞庭湖、南洞庭湖和东洞庭湖首尾相接三个部分,具有“高水湖相,低水河相”的典型特征。洞庭湖区不但是我国受洪水威胁最严重的地区之一,而且生态退化和环境问题也十分突出,一直受到国家的高度重视。文章在大量调查的基础上,对洞庭湖及其湖区的生态环境退化状况、产生原因和可能带来的负面影响等方面进行了初步分析。     

An overview of the environmental finance policies in China: retrofitting an integrated mechanism for environmental management

Considering the significant roles of the policies in developing environmental finance, an overview is conducted on the environmental finance policies （EFPs） in China. This paper analyzed the definition, scope, evolution and main instruments of EFPs. The implementation progress of financial activities on each instrument are investigated respectively. Then the experiences learned from and failures discovered in the development of the EFPs are discussed well recommendations for further improvement of the EFPs and their implementation are provided. Our study found that the EFPs have been established in China after a four-phase evolution since the early 1980s. The policies have played a critical role in leading to a rapid development in environmental finance by involving more financial instruments to accomplish the objective-led environmental plans. Driven by the policies, the new green credit （GC）, green security （GS）, and green insurance （GI） instruments have been phased in as supplements to the conventional command and control approaches to improve the environmental governance of financial activities and pollution sources. However, the market mechanism of financial institution is limited due to their defensive and incapable performance on implementation some of EFP instruments. To further strengthen the effectiveness of EFPs in facilitating environmental man- agement, recommendations are made mainly on the aspects including developing more specific policy guidelines, enhancing information sharing and disclosure, providing sufficient economic incentives, establishing environmental liabilities with financial activities, and involving issues related to climate change, and biodiversity and ecosystem service.     

中国快速城镇化的边际环境污染效应变化实证分析

通过建立模型并实际测算城镇化每增长1个百分点引起的污染物产排放变化量,来分析我国城镇化发展的边际环境污染效应。结果显示,我国城镇化发展与环境污染之间的矛盾仍十分突出,1996-2009年期间,城镇化每增长1个百分点带来的城镇生活污水排放量、COD产生量、NH3-N产生量、NOx排放量、CO2排放量、城镇生活垃圾产生量仍呈上升趋势。由于近年来城镇污水处理率明显提升,城镇化每增长1个百分点带来的COD和NH3-N排放量由＂十五＂的增加逐步转为＂十一五＂的减少;由于城镇生活用煤的减少,城镇化每增长1个百分点带来的SO2排放量在＂十五＂＂十一五＂期间都呈减少趋势。为减少环境污染,我国应选择有中国特色的城镇化发展道路,合理把握城镇化发展速度和节奏,促进城镇与环境协调发展。     

Review of challenges and strategies for balanced urban–rural environmental protection in China

With the rise of environmentalism in China, great efforts have been devoted to environmental protection over the past several decades. Compared with urban environmental protection, rural environmental protection has not been attached enough importance in China due to the dual-track structure of socio-economic development. As a result, rural China is shouldering disproportionally heavy environmental burdens partly because of the differences and biases between urban and rural environmental protection seen in environmental policies, environmental rights and interests, environmental protection investment, and the environmental protection awareness of people. To eliminate the gap between rural and urban environmental protection, and achieve the goal of “balanced urban–rural environmental protection” (BUREP), government should consider mapping out proper policies and strategies. In this paper we put forward an innovative strategy of BUREP against the background of China’s urban-rural environmental protection. First, we review the current status of rural environmental protection status and its challenges compared with urban environmental protection in China. Secondly, we analyzed the main driving factors and reasons deeply, and then we put forward the BUREP strategy base on the unequal status between urban and rural environment. Finally, we proposed the framework of BUREP. This study may serve as a scientific reference regarding decision-making in coordinating urban and rural environmental protection and in constructing the new countryside of China.     

Tourism policy,biodiversity conservation and management: a case of the Kruger National Park,South Africa

Management of Kruger National Park (KNP) has recently made considerable progress in developing new policies to address biodiversity conservation and management challenges. These include tourism, water provision and elephant management policies. This study examines the integration of these three policies with regard to biodiversity conservation and management. Findings indicate that in their current fragmented form, the three policies actually undermine opportunities for effective biodiversity conservation and management in the KNP. This can be reversed by adopting a new management approach based on an environmental matrix organizational framework. Such a framework provides a mechanism for integrated policymaking and implementation and for improving biodiversity conservation and management in the KNP. The study concludes that an integrated approach is necessary due to the interlinkages between policies that affect biodiversity conservation at the KNP.     

The transition from dirty to clean industries: optimal fiscal policy and the environmental Kuznets curve

This paper investigates privately and socially optimal patterns of economic development in a two-sector endogenous growth model with clean and dirty goods. We consider a second-best fiscal policy framework in which distortionary taxes jointly influence economic growth and environmental quality. In this policy setting, three conditions produce an Environmental Kuznets Curve (EKC): (i) dirty output is bounded; (ii) clean output grows endogenously; and (iii) growth in the dirty sector reduces growth in the clean sector. These conditions do not arise with a consumption externality, but can emerge with a production externality. Endogenous labor supply implications are also investigated. Although not necessary for producing an EKC, endogenous labor supply provides additional linkages that produce an EKC under circumstances in which it would otherwise not appear.

Analyzing the effectiveness of international environmental policies: The case of the Kyoto Protocol

We study the effectiveness of emission targets under the Kyoto Protocol with respect to reducing CO₂ emissions. Using country-level and US state-level panel data and employing the synthetic control method, we find very little evidence for an emission reduction effect for the major emitters among the Annex B countries with binding emission targets. More generally, we also show that evaluating the effectiveness of international environmental policies at the country level comes with a number of empirical challenges that may invalidate findings based on more traditional panel data approaches.     

国外的环境移民问题及启示

工业的发展、人口的不断增长、经济全球一体化、气候变化等,导致生态环境的持续恶化,环境移民已成为困扰世界社会经济可持续发展的严重问题之一。国际社会的环境移民状况表明,环境移民主要是自发性的移民,缺乏政府的主导,容易形成环境难民和种族冲突,移民的人权难以得到保证,也不具有可持续发展性;可持续的环境移民要以政府为主导,以国内迁移为主实施移民工程;环境移民工程需要借鉴世界银行工程移民的经验,关键是做好迁人地的选择和评估。未来气候变化和突发环境灾难将不断加大人口的迁移范围和规模,需要给予特别的关注。总结国外环境移民的经验和教训,对我国实施有效的环境移民具有十分重要的意义。     

环境科学技术进步贡献率测算方法探讨

运用科技进步计量测算模型，对江苏省１９８０～１９９３年科技进步在控制环境污染中的贡献率和影响程度进行定量分析。结果表明，科技进步对江苏省环境保护事业的贡献率仅占６．８４％，远未发挥出其应有的作用。     

农村环境质量区划原则及指标体系

目前工业“三废”对农村环境污染的发展趋势有所减缓，但乡镇工业对农村环境污染的比重仍在逐渐增大，污染势头继续增强。从整体上讲，农村环境质量继续恶化的趋势尚未得到有效的控制。为加强农村环境质量的管理，本文着重论述了农村环境质量区划应遵循的４条原则，以层次分析法为原理，从自然生态环境、人类开发强度、环境状况３个方面，提出由２８个指标组成的农村环境质量区划指标体系，该指标体系简便适用、易于操作，对不同层次、不同地区的具体区划具有指导意义。     

农业化肥污染的政策成因及对策分析

化肥污染是农村面源污染的重要组成部分,如何解决该问题已经成为中国学者热议的话题。为了定量分析国家政策对化肥过量施用的影响,基于我国1998—2007年各省市的面板数据,借助STATA软件包和化肥施用效用模型假设,对其进行了回归分析。结果表明：一是随着经济发展水平的提升,农业化肥污染仍会不断加剧。二是多年来国家给予化肥企业＂优惠＋补贴＋限价＂的化肥行业发展政策是化肥过量施用的根本政策原因,当前国家惠农政策有助于降低化肥的需求量。三是当国家取消对化肥企业的补贴政策,继续当前的惠农政策时,则农民直补政策需以农民有利于环境的施肥方式为前提。四是若国家继续当前化肥行业发展政策和惠农政策,则视国家给予化肥企业的补贴确定一个直补额度,当对农民直补小于该额度时,则直补有利于农民减少对化肥的需求;但当直补超过这一额度时,农民则会增加对化肥的需求,因此后者需以农民施肥行为有利于环境为前提。     

中国农产品产地环境标准中存在的问题与对策研究

目前中国已经颁布的各类产地环境类标准已超过30多个(不含地方标准)，与欧美发达国家同类标准相比，中国现行的产地环境类标准普遍存在着制定程序不严谨、相关标准之间衔接统一不够、标准的科学技术水平不高、标准的针对性与实用性不强、标准与分析检验方法不配套等共同的问题。通过实例和数据，对以上问题进行了研究和分析，提出了改革现行的标准管理模式、加强基础性科学研究、借鉴和引进国际先进标准、培育专业技术队伍等对策措施。

国家濒危植物永瓣藤分布的土壤环境特征

永瓣藤(Monimopetalum chinense)是卫矛科(Celastraceae)的一个中国特有单型属植物,被列为国家二级稀有濒危保护物种。本文对永瓣藤分布区14个样地土壤样品的pH值、有机质、全氮、水解氮、硝态氮、全磷、速效磷和全钾进行了检测分析,以期弄清该物种分布与土壤环境因子的关系。结果表明,其pH值的变化幅度为4.55～5.57,主要处于强酸性范围,适应幅度较窄。有机质与氮素非常丰富,相互间具有明显的相关性,有利于永瓣藤的生长与繁衍,但土壤中磷、钾素较为缺乏。土壤酸碱度和有机质的质量分数在某种程度上对永瓣藤的分布范围具有制约作用。     

Moving towards sustainable development: rhetoric,policy and reality of ecological agriculture in China

Past decades have witnessed the rise of sustainable agriculture movements throughout the world. In parallel with this international trend, ecological agriculture (with essential goals of food security, rural employment, poverty alleviation, natural resource management and environmental protection) has been advocated as a workable approach for the realization of sustainable agriculture in China. Two decades of ecological agricultural development have shown that it not only gained legitimacy at the senior policy level but also became a focus of scientific research in fields such as ecological economics, ecology, and agricultural and environmental sciences. However, this endeavour is hardly known in the West and little attention has been paid so far to examining the broader politico-economic and sociocultural contexts within which it has evolved. This paper attempts to provide a general review of the emerging background, development history, policy initiatives and recent tendencies of ecological agriculture. In addition, the extant problems and potential contributions of this alternative practice to China's sustainable agricultural development are discussed. The purpose of this study is to identify the gap between the policy rhetoric and practical implementation of Chinese ecological agriculture and therefore to facilitate its moving towards sustainable development.     

绿色食品生产补偿的理论机理与政策设计

制约我国绿色食品发展的重要因素之一是其生态环境成本难以通过市场来兑现。为解决这一问题,文章以生态补偿为突破口,首先从理论上明确绿色食品生产具有正外部性,政府对其生产企业或农户进行补偿具有合理性和必要性,然后进一步探讨其制度构建与政策设计。（1）构建一个包括政府、生产者、消费者三方的博弈模型,着重分析绿色食品供需过程中、政府影响下生产者和消费者的利益动机和博弈行为。模型结果显示,存在能够满足绿色食品供需平衡的1个纯战略纳什均衡解和1个混合战略纳什均衡解,这两个纳什均衡解的实现条件均要求政府对绿色食品生产者提供补偿和对消费者实施优惠政策。（2）利用C-D生产函数建构的利润函数和恢复费用法探讨绿色食品生产补偿标准范围,结果表明最低补偿标准应满足生产者生产绿色食品和生产普通食品利润相等,而最高补偿标准则应对绿色食品生产中创造的环境效益进行支付。（3）文章最后从“建立经济政策支持体系,构筑科技进步支撑体系,完善品牌质量保障体系,培育产业化生产体系”等4方面提出了现阶段我国绿色食品生产补偿的政策建议。
