Since many soil studies have already revealed the possible risks to human health and the environment arising from contaminated soils it is therefore crucial to preserve soil quality under current and future conditions. In the last three decades a number of countries already introduced national policies and practices for the management of contaminated sites, and in 2002, an EU Thematic Strategy for Soil Protection was proposed by the European Commission. In this paper we review and analyse several national contaminated land policy regimes already in place in order to assess common elements and to identify specific needs in the development of national soil policies. We propose a framework that combines the D-P-S-I-R structure of policy evaluation with the Source-Pathway-Receptor approach to health risk assessment to support the development of effective country specific regulatory decisions for managing contaminated land in countries where these are yet to be implemented. The framework proposed allows decision makers to effectively use available information and to identify existing data gaps. As a result it is apparent that while there are technical aspects of site characterisation, risk assessment and remediation processes that could be commonly implemented at an EU level there are certain trans-scientific aspects that require political choices and need to be customized by EU Member States.  相似文献

The article deals with indicators framework to monitor implementation of the main EU (European Union) directives and other policy documents targeting sustainable energy development. The main EU directives which have impact on sustainable energy development are directives promoting energy efficiency and use of renewable energy sources, directives implementing greenhouse gas mitigation and atmospheric pollution reduction policies and other policy documents and strategies targeting energy sector. Promotion of use of renewable energy sources and energy efficiency improvements are among priorities of EU energy policy because the use of renewable energy sources and energy efficiency improvements has positive impact on energy security and climate change mitigation. The framework of indicators can be developed to establish the main targets set by EU energy and environmental policies allowing to connect indicators via chain of mutual impacts and to define policies and measures necessary to achieve established targets based on assessment of their impact on the targeted indicators representing sustainable energy development aims. The article discusses the application of indicators framework for EU sustainable energy policy analysis and presents the case study of this policy tool application for Baltic States. The article also discusses the use of biomass in Baltic States and future considerations in this field.  相似文献

Coastal areas are the focus of intensive urbanisation and tourism and are subject to changing physical processes causing significant natural environment modifications. It is in this context that the European Commission (EC) developed the Integrated Coastal Zone Management (ICZM) Recommendation and invited coastal Member States to produce national implementation strategies. Its general aim of sustainable coastal development was based on policy integration in cooperation with all stakeholders in an informed and participatory context. Portugal responded to the EC request by creating, approving, and adopting the national ICZM strategy. This paper focuses on Portuguese experiences putting the ICZM recommendation into practice and begins with a brief overview of community guidelines, national legislation, and implementation. Subsequently, governance mechanisms are discussed and best practice identified. From an assessment of Portuguese ICZM progress and lessons learned, conclusions and recommendations for improved effectiveness included: strengthening governance; improving sustainable decision-making processes supported by technical and scientific knowledge; and securing financial sustainability.  相似文献

Large scale (e.g. regional or national) assessments of contaminated sites may be very costly in terms of investigation and methodological (i.e. risk assessment procedures) requirements and may produce a quantity of information that usually discourages examination by decision-makers. Moreover, most of the existing tools effectively support local environmental risk assessment and management, but lack the capabilities of larger scale analysis, not mentioning the absence of the relevant component of socio-economic prioritization. To respond to the concerns and the management needs of experts and decision makers, the Spatial decision support sYstem for Regional rIsk Assessment of Degraded land (SYRIADE DSS) was developed and is presented according to its three modules: Regional Risk Assessment, Socio-economic Assessment and Integrated Assessment, respectively. The system allows to rank potentially contaminated sites for priority of investigation, when no information on characterization and risk by site specific methodologies is available. This GIS-based system embeds an innovative spatial and relative risk assessment procedure, and proposes the integrated analysis of different data (environmental and socio-economic) for the concerned sites, eliciting when necessary experts' knowledge and stakeholders' values (through Multi Criteria Decision Analysis, MCDA, methodologies). The application to a Polish case-study shows the performance and the flexibility of the system in investigating and mapping (potentially) contaminated sites at the regional scale.  相似文献

2015年9月《中美元首气候变化联合声明》宣布中国将于2017年启动全国性碳排放交易体系以来,中国碳市场的筹建及7大试点的运行备受国内外媒体和学术界的关注。相关预测显示,中国碳市场届时将一举超过目前全球最大的欧盟碳排放交易体系EU ETS成为世界第一大碳交易市场,但由于7个试点运行时间较短、试点地区重视程度以及建设侧重点不统一等原因,目前中国碳市场存在着监管机构职责不清、监管体系不健全、监管政策不到位等一系列问题。本研究从监管机构、监管政策、技术支持平台、监管内容等方面梳理和分析了中国7个试点碳市场的监管体系,并将其与EU ETS、RGGI等国际上发展较为成熟的碳市场监管体系进行了对比分析后发现:1在监管手段方面,EU ETS与RGGI均侧重于依靠法律手段,而中国碳市场的监管手段则主要以地方性规范文件为主;2在监管机构职能方面,EU ETS的二级管理体系有效划分了监管范畴,保证了各级监管力度。RGGI的第三方独立监管模式则很好的保证了监管的公平性,充分发挥了碳市场事中监管作用,而中国碳市场则主要依赖于地方发改委来进行监管,存在职责划分不明晰等问题;3在监管重心方面,EU ETS侧重于对市场运行中的操作性风险和交易性风险进行防范,RGGI则更加关注交易风险的实时监控,而中国碳市场目前主要针对市场价格波动风险进行了防范。由此对中国即将建立的全国性碳市场监管机制设计提出了如下建议:1提高碳市场立法效力,完善监管政策体系;2平衡监管权力,成立专职监管机构;3加强过程监管,完善电子平台安全建设;4加大碳市场信息披露力度,鼓励公众及行业协会参与,形成外部监督机制。  相似文献

Forest administrators play a crucial role in translating conservation and development policies into action, yet policy reformers and scholars rarely examine how these administrators make decisions about the implementation of conservation and development policy in India. In this paper, I address this gap. I begin by developing a framework that draws on Western policy implementation studies and Ostrom’s Institutional Analysis and Development framework and then apply this framework to a review of published studies that examine the role of forest officials in implementing public policies in India. The framework differentiates between formal and informal institutions and between institutions which are developed within an agency and those that are directed from outside the agency. I find that forester behavior varies significantly across space and time and has an important influence on the outcome of forestry programs. Innovations and excellent program implementation appear related to foresters’ desire to demonstrate professional efficacy. On the other hand, many failings can be traced either to external direction or to foresters developing internal institutions that are poorly suited to the problems they are tasked with solving. Existing research is limited in its geographic and temporal scope and leaves many questions unanswered, and thus, the review concludes with a brief outline of future research needs.  相似文献

Material resources exploitation and the pressure on natural ecosystems have raised concerns over potential future resource risks and supply failures worldwide. Interest in the concept of Circular Economy has surged in recent years among policy makers and business actors. An increasing amount of literature touches upon the conceptualisation of Circular Economy, the development of ‘circular solutions’ and circular business models, and policies for a Circular Economy. However, relevant studies on resource efficiency policies mostly utilise a case-by-case or sector-by-sector approach and do not consider the systemic interdependencies of the underlying operational policy framework. In this contribution, a mapping of the existing resource policy framework in the European Union (EU) is undertaken, and used as a basis for identifying policy areas that have been less prominent in influencing material resource efficiency. Employing a life cycle approach, policies affecting material efficiency in the production and consumption stages of a product have been found to be poorly utilised so far in the EU. Taking this as a point of departure, three policy areas that can contribute to closing material loops and increasing resource efficiency are thoroughly discussed and their application challenges are highlighted. The three policy areas are: (1) policies for reuse, repair and remanufacturing; (2) green public procurement and innovation procurement; and (3) policies for improving secondary materials markets. Finally, a potential policy mix, including policy instruments from the three mentioned policy areas—together with policy mixing principles—is presented to outline a possible pathway for transitioning to Circular Economy policy making.  相似文献

This paper reviews the progress in climate change adaptation (CCA) policies both under the United Nations Framework Convention on Climate Change (UNFCCC) and in major regions and countries, including the EU and its major member countries, the influential developed countries in the Asia-Pacific region, the emerging economies and the least developed countries (LDCs). The progress made in China in CCA policies is also reviewed and compared with that in other countries. Finally, good international practices are proposed for China’s policy development. It is found that adaptation has been given the same priority as mitigation since the twenty-first century with regard to climate change-related actions. The topics related to adaptation in the international climate change negotiations under the UNFCCC have evolved from mechanisms for finance and technology development and transfer exclusively in the early stages to implementation of practical adaptation programs and actions. Since 2006, major developed and developing countries have frequently set forward specific CCA policies or general climate change policies involving adaptation in the form of laws, frameworks, strategies, and plans. The LDCs have also been working on National Adaptation Programmes of Action and subsequent National Adaptation Plans with the support from the financial mechanisms under the UNFCCC. Therefore, globally, it has become a common practice to develop national or regional policies to plan and guide CCA actions. China has established climate change policies involving adaptation at the national, regional, and sectorial levels since 2007. However, these policies have strong limitations in their knowledge base, strategic positioning, contents, and implementation mechanisms, e.g. lack of a sound knowledge base, an international perspective, clear responsibilities for policy implementation, and appropriate monitoring and evaluation mechanisms. It is recommended that China should further strengthen its technical capabilities in climate change projections as well as impact, vulnerability, and risk assessment, and develop methodologies and techniques for the preparation, impact assessment and implementation of CCA policies. Furthermore, future CCA strategies or plans should be developed with an emphasis on China’s vision and strategic position on the world stage.  相似文献

Environmental risks are traditionally assessed and presented in non spatial ways although the heterogeneity of the contaminants spatial distributions, the spatial positions and relations between receptors and stressors, as well as the spatial distribution of the variables involved in the risk assessment, strongly influence exposure estimations and hence risks. Taking into account spatial variability is increasingly being recognized as a further and essential step in sound exposure and risk assessment. To address this issue an innovative methodology which integrates spatial analysis and a relative risk approach was developed. The purpose of this methodology is to prioritize sites at regional scale where a preliminary site investigation may be required. The methodology aimed at supporting the inventory of contaminated sites was implemented within the spatial decision support sYstem for Regional rIsk Assessment of DEgraded land, SYRIADE, and was applied to the case-study of the Upper Silesia region (Poland).The developed methodology and tool are both flexible and easy to adapt to different regional contexts, allowing the user to introduce the regional relevant parameters identified on the basis of user expertise and regional data availability. Moreover, the used GIS functionalities, integrated with mathematical approaches, allow to take into consideration, all at once, the multiplicity of sources and impacted receptors within the region of concern, to assess the risks posed by all contaminated sites in the region and, finally, to provide a risk-based ranking of the potentially contaminated sites.  相似文献

As highlighted in the EU Soil Communication, local contamination is one of the main soil threats and it is often related to present and past industrial activities which left a legacy of a high number of contaminated sites in Europe. These contaminated sites can be harmful to many different receptors according to their sensitivity/susceptibility to contamination, and specific vulnerability evaluations are needed in order to manage this widely spread environmental issue. In this paper a novel comprehensive vulnerability assessment framework to assess regional receptor susceptibility to contaminated site is presented. The developed methodology, which combines multi criteria decision analysis (MCDA) techniques and spatial analysis, can be applied to different receptors recognized as relevant for regional assessment. In order to characterize each receptor, picked parameters significant for the estimation of the vulnerability to contaminated sites have been selected, normalized and aggregated by means of multi criteria decision analysis (MCDA) techniques. The developed MCDA methodology, based on the Choquet integral, allows to include expert judgments for the elicitation of synergic and conflicting effects between involved criteria and is applied to all the geographical objects representing the identified receptors. To test the potential of the vulnerability methodology, it has been applied to a specific case study area in the upper Silesia region of Poland where it proved to be reliable and consistent with the environmental experts' expected results. The vulnerability assessment results indicate that groundwater is the most vulnerable receptor characterized by a wide area with vulnerability scores belonging to the highest vulnerability class. As far as the other receptors are concerned, human health and surface water are characterized by quite homogeneous vulnerability scores falling in the medium-high vulnerability classes, while protected areas resulted to be the less vulnerable receptor with only one protected area falling in the medium vulnerability class. The vulnerability assessment results will support the regional risk assessment for the ranking of potentially contaminated sites at regional scale.  相似文献

Southeast China is one of the severe soil degradation areas in China. This paper theoretically examines the impact of some important institutional arrangements and policies, like land management pattern, the rural off-farm employment, land property change and changes in prices of agricultural products, on soil degradation in this area. It further conducts some case studies to confirm the potential relationship between the institutions & policies and soil degradation, applying the surveyed and the second hand data. The paper at last makes some conclusions and proposes some suggestions on how to promote soil conservation by improving the ways of policy decision-making and the effects of policies on land use.  相似文献

The study presents three scenarios of land use and cover change (LUCC), the most important factor for environmental degradation in southern Mexico. We developed story lines and quantitative projections for regional scenarios based on historic LUCC processes, environmental policies, socioeconomic drivers, stakeholder consultations and official planning documents to gain a better understanding of drivers of LUCC, and quantitative scenarios were modeled with DINAMICA-EGO. Regionally specific interactions between social and natural systems are recognized, and detrimental policies and policy options for landscape conservation and management for sustainability are acknowledged in a base line, variant and alternative scenario. Incongruent policies and ineffective ground implementation of conservation actions were identified as the critical underlying drivers of deforestation and forest degradation that could lead to a severe reduction in natural forests, while the local socioeconomic situation stays precarious. The baseline scenario parts from an analysis of historic LUCC processes and shows the consequences of LUCC tendencies: 73% of temperate forests and 50% of tropical forests would get deforested until 2030. In the variant scenario, these tendencies are adjusted to planning goals extracted from official documents and recent changes in public policies. The alternative scenario further addresses policy options for fostering conservation and sustainable development, but because of the time lag of implementation, still 59% of temperate forests and 36% of tropical forest would get lost until 2030. Nevertheless, this represents a reduction of 13% of forest loss and 11% less pastureland due to the proposed measures of conservation, and sustainable management, including strategies for reforming agricultural systems, agricultural and forestry policies and trade, land tenure and livelihood risk management.  相似文献

Environmental risk assessment and decision-making strategies over the last several decades have become increasingly more sophisticated, information-intensive, and complex, including such approaches as expert judgment, cost-benefit analysis, and toxicological risk assessment. One tool that has been used to support environmental decision-making is comparative risk assessment (CRA), but CRA lacks a structured method for arriving at an optimal project alternative. Multi-criteria decision analysis (MCDA) provides better-supported techniques for the comparison of project alternatives based on decision matrices, and it also provides structured methods for the incorporation of project stakeholders' opinions in the ranking of alternatives. We argue that the inherent uncertainty in our ability to predict ecosystem evolution and response to different management policies requires shifting from optimization-based management to an adaptive management paradigm. This paper brings together a multidisciplinary review of existing decision-making approaches at regulatory agencies in the United States and Europe and synthesizes state-of-the-art research in CRA, MCDA, and adaptive management methods applicable to environmental remediation and restoration projects. We propose a basic decision analytic framework that couples MCDA with adaptive management and its public participation and stakeholder value elicitation methods, and we demonstrate application of the framework to a realistic case study based on contaminated sediment management issues in the New York/New Jersey Harbor.  相似文献

中国设区市土地集约利用类型区划分研究   总被引:8,自引:0,他引:8  
中国的基本国情之一是地区差异明显。在进行城市集约利用评价或制定相关标准时,由于存在这种差异,导致很多政策执行不力。在人们高度重视城市土地集约利用研究时,如何进行差别对待,因地制宜,需要从类型区的角度进行研究。本文以设区城市为研究对象,在对《城市统计年鉴》进行统计分析的基础上,采用"统计分析+使用频率"方法,筛选出共4类24个指标,借助统计资料和GIS技术,划分了4个一级集约利用类型区以及各区中的17个亚区,并建立了亚区命名体系。结果显示:(1)城市土地集约利用程度大致为东高西低。东部城市多为Ⅰ、Ⅱ级,中部城市多为Ⅲ级,西部城市多为Ⅳ级。(2)城市土地集约程度和城市经济状况存在不完全吻合现象,表现在一些城市经济情况相对比较好,但是土地集约利用程度却不高。这在中部城市表现得十分明显。由此得出结论,采用本文的研究思路和方法可以较好地解决城市土地集约利用的差异管理问题,并可进行动态更新,使政策制定和管理更具操作性。  相似文献

To be effective, climate change adaptation needs to be mainstreamed across multiple sectors and greater policy coherence is essential. Using the cases of Malawi, Tanzania and Zambia, this paper investigates the extent of coherence in national policies across the water and agriculture sectors and to climate change adaptation goals outlined in national development plans. A two-pronged qualitative approach is applied using Qualitative Document Analysis of relevant policies and plans, combined with expert interviews from non-government actors in each country. Findings show that sector policies have differing degrees of coherence on climate change adaptation, currently being strongest in Zambia and weakest in Tanzania. We also identify that sectoral policies remain more coherent in addressing immediate-term disaster management issues of floods and droughts rather than longer-term strategies for climate adaptation. Coherence between sector and climate policies and strategies is strongest when the latter has been more recently developed. However to date, this has largely been achieved by repackaging of existing sectoral policy statements into climate policies drafted by external consultants to meet international reporting needs and not by the establishment of new connections between national sectoral planning processes. For more effective mainstreaming of climate change adaptation, governments need to actively embrace longer-term cross-sectoral planning through cross-Ministerial structures, such as initiated through Zambia’s Interim Climate Change Secretariat, to foster greater policy coherence and integrated adaptation planning.  相似文献

Ensuring forest protection and the delivery of forest ecosystem services is a central aim of the European Union’s biodiversity strategy for 2020. Therefore, accurate modelling and mapping of ecosystem services as well as of biodiversity conservation value is an important asset in support of spatial planning and policy implementation. The objectives of this study were to analyse the provision of the multiple ecosystem services under two forestation scenarios (eucalyptus/pine vs. oak) at the watershed scale and to evaluate their possible trade-offs with the biodiversity conservation value. The Vez watershed, in northwest Portugal, was used as case study area, in which soil and water assessment tool (SWAT) was applied to simulate the provision of hydrological services, biomass and carbon storage services. Biodiversity conservation value was based on nature protection regimes and on expert judgement applied to a land cover map. Results indicated large provision of ecosystem services in the high and low mountain sub-basins. The overall performance for water quantity and timing is better under the shrubland and oak forest scenarios, when compared to the eucalyptus/pine forest scenario, which perform better for flood regulation and erosion control services, especially in the low mountain sub-basin. The current shrubland dominated cover also shows good performance for the control of soil erosion. The oak scenario is the one with less trade-offs between forest services and biodiversity conservation. Results highlight SWAT as an effective tool for modelling and mapping ecosystem services generated at the watershed scale, thereby contributing to improve the options for land management.  相似文献

In the context of renewed interest in collaboration in natural resource management,the collaborative governance approach has lately been introduced to the forest Protected Areas(PAs)in Bangladesh.The adoption of this co-management approach is seen as an attempt to influence the governance process towards a transformation from the conventional custodian system to a more participatory management regime.Recognition of rights and responsibilities,effective participation,and equitable distribution of benefits amongst the key stakeholders working under a facilitative policy and legal framework are believed to address the broader goals of sustainable development Notwithstanding the resurgence of interest in governance of forest PAs through the co-management approach,academic research on the subject remains limited.This article attempts to review selected key information and milestones on the forest PAs governance with special reference to the major policies and legal documents.With a brief introductory section,this article focuses on the genesis and selected major features of the Forest PAs in the country.The discussion then dwells on the policy and legal framework and provides a critique on its relevance for promoting community participation.The existing institutional arrangements for community engagement in protected area governance are also analyzed in light of the national and international commitment and policy obligations on the part of the country.The salient observations and key findings of the study include the following:(1)despite its limitations,comanagement as concept and practice has gradually taken roots in Bangladesh;(2)the degree and level of active community participation remain low and limited,and there is also clear weakness in conscientizing and orientating the local community on the key legal and policy issues related to PA governance in the country;and(3)policy makers,practitioners,and other local stakeholders related to PA governance need to be oriented on international commitment and national de  相似文献

The 2030 agenda for sustainable development adopted in September 2015 advocates for a balanced integration of the economic, social and environmental dimensions of sustainable development. Existing multilateral environmental agreements (MEAs) can provide guidance for policy-makers to promote inclusive and sustainable economic growth, within safe ecological limits. This paper presents a practical approach to mainstream international obligations of MEAs with national development priorities and strategies. It identifies pathways of policy coherence from national strategies to specific instruments and indicators to advance implementation of MEAs and help counties to fulfill agreed obligations. The approach is grounded in the driving forces–pressure–state–impact–response (DPSIR) framework, and it was applied in two national and two regional case studies in the Caribbean. The outcomes from the case studies show that mainstreaming rate of MEAs is low, and linkages across multiple MEAs are rarely considered. The DPSIR framework was useful for addressing national development priorities and those of MEAs in tandem, through adopting a cross-sectoral, multistakeholder perspective. The research shows that addressing environmental degradation and improving MEAs’ implementation requires that international and regional agencies identify linkages among MEAs to assist in creating policy coherence to ensure their integration into national strategies by connecting with policies and strategies in tandem implementation of MEAs for national policy-makers to work with.  相似文献
