环境影响评价自引入我国以来,经过40多年发展,已形成一套具有我国国情特点的成熟制度框架体系. 为探究过去40年我国环境影响评价研究的发展与演变特征,以1980—2020年科睿唯安(Web of Science)和中国知网收录文献作为研究对象,运用CitesSpace文献分析工具,绘制环境影响评价领域知识图谱,对比分析国内外环境影响评价的研究力量、时空演变特征等信息,重点分析得出我国环境影响评价领域研究热点;结合聚类分析实证结果,从研究方向、指导理念、制度完善、技术体系四个方面总结了我国环境影响评价领域的演变特征和重点领域发展趋势,并提出新时期环境影响评价的展望与设想. 值得注意的是,相较于国际学术界对环境影响评价研究热度持续上升,我国对环境影响评价研究的关注度正在下降,学术影响力不够、学科交叉研究不足,一定程度制约了环境影响评价制度的纠错能力与创新能力的提升. 为切实提高环境影响评价协同推进高质量发展和高水平保护的能力,一方面需进一步发挥制度优势,对标国际先进技术,加强环境影响评价与公共管理等其他学科的交叉融合研究,完善经济、技术政策环境评价顶层设计,加强生物多样性、气候变化等全球性问题在环境影响评价中的融合研究;另一方面,应推动我国环境影响评价实践经验走向国际学术界,提升环境影响评价国际学术话语权,不断创新形成具有“中国特色、世界一流”的环境影响评价体系.   相似文献

In the context of complex and unprecedented issues of global change, calls for new modes of knowledge production that are better equipped to address urgent challenges of global sustainability are increasingly frequent. This paper presents a case study of the new major research programme “Future Earth”, which aims to bring ‘research for global sustainability’ to the mainstream of global change research. A core principle of Future Earth is the co-production of knowledge with extra-scientific actors. In studying how the principle of co-production becomes institutionalised in the emerging structure of Future Earth, this paper points to the existence of three distinct rationales (logics) on the purpose and practice of co-production. Co-production is understood as a way to enhance scientific accountability to society (‘logic of accountability’), to ensure the implementation of scientific knowledge in society (‘logic of impact’), and to include the knowledge, perspectives and experiences of extra-scientific actors in scientific knowledge production (‘logic of humility’). This heterogeneous conception of knowledge co-production provides helpful ambiguity allowing actors with different perspectives on science and its role in society to engage in Future Earth. However, in the process of designing an institutional structure for Future Earth tensions between the different logics of co-production become apparent. This research shows how logics of accountability and impact are prominent in shaping the development of Future Earth. The paper concludes by pointing to an essential tension between being inclusive and transformative when it comes to institutionalising new modes of knowledge production in large research programmes.  相似文献

There is a well-recognised need to transform existing systems of production and consumption towards a more sustainable orientation. However, there is much uncertainty about how to achieve sustainability transitions in practice, and what transition advocates and actors can do to catalyse and steer regime transformation. We therefore need evidence of how transitions are operationalised, in order to better understand the on-ground dynamics of regime change. To address this gap, this research paper examines three contemporary cases of transformational change in the Australian urban water sector and the dominant strategic approach to change adopted in each city. It focuses on the strategic behaviour of actors, in particular examining how agents navigate and respond to the opportunities and constraints of their context, and what initiatives (or combination thereof) can facilitate innovation diffusion and regime transformation. The results reveal three distinct patterns of change, each of which favour particular strategic interventions by transition proponents.In order to incubate transformational change, the results suggest that actors may be best served by initially employing strategies that are immediately compatible with their existing context. However, examination of the strengths and weaknesses of each pattern confirm that no single strategic approach is in itself sufficient, and in order to embed a novel innovation and bring about regime change, actors will eventually need to broaden the range of interventions used. The results also reveal the possibility of a ‘pattern-dependence’ that actors need to deliberately work to overcome in order to fully mainstream the desired change. These findings therefore provide insight into the links between regime transformation, patterns of change and actor strategies while also offering practical guidance that can be used to inform the design and implementation of regime transformation agendas and programs.  相似文献

Market-based instruments along with conceptualizing the environment as a collection of ‘ecosystem services’ has become increasingly common within environmental and conservation policy. This kind of thinking is also increasingly prominent in the public discourse surrounding environment and conservation policy, particularly in the context of communicating the importance of policy measures. Language used in public discourse can have a powerful influence on how people engage with policy issues, and changes within the biodiversity and conservation discourse may have consequences for public engagement in conservation. We explored how these factors are changing with time by documenting the use of the terms ‘bio’ and the prevalence of economic language in the text of 3553 media releases between 2003 and 2014 from the Australian Government environment portfolio, and 1064 media releases from the Australian Conservation Foundation (ACF). Results show that in the last decade, the term ‘biodiversity’ has become less prevalent whilst economic language has increased in both Australian Government and ACF communication. A further content analysis in a subsample of 745 media releases explored the prevalence of ecosystem services framing, results indicating that it has become a mainstream concept. While this may reflect a strategic response by these agencies to better engage with both the general public and decision makers within what is an increasingly dominant neoliberal paradigm, we argue it may also have unintended (possibly adverse) impacts on how people think about and engage with biodiversity conservation.  相似文献

Environmental policies are broadly claimed to rely on sound scientific evidence because of the complexity, the uncertainty and the diverging political stakes that characterize issues like biodiversity decline or climate change. Classical advisory formats like assessments or standing advisory bodies have proliferated widely – especially at the global and national levels – yet exert only a limited influence on political decision-making, particularly in sub-national and local implementation contexts. Against this background, scholars have called for ‘bottom-up’ approaches to Science-policy interfaces that move from ‘problem to policy’. In the area of climate change, numerous ‘climate services’ have evolved at national, sub-national and even local levels, with the promise of being more decision-oriented. Four climate services in three European countries (the United Kingdom, Germany and Switzerland) are investigated regarding whether and how they institutionalize and enact knowledge brokerage in a credible, salient and legitimate way. Focusing on the institutional and strategic design principles of this advisory setting in climate policy, insights are generated for the biodiversity policy field, where comparable settings are still broadly lacking.  相似文献

Modern industrial environmental management encompasses life-cycle thinking. This entails considering not only the emissions and resource use of the company’s production processes, but also the environmental consequences of all processes related to a product’s life cycle. However, no single actor can influence the whole life cycle of a product. To be effective, analysis methods intended to support improvement actions should therefore also consider the decision makers’ power to influence.Regarding the life cycle of a product, there are at least as many perspectives on life-cycle thinking as there are actors. This paper presents an approach with which manufacturing decision makers can sharpen the focus in life-cycle assessment (LCA) from a conventional ‘products or services’ emphasis to a company’s manufacturing processes. The method has been developed by combining knowledge gained from earlier LCA studies with new empirical findings from an LCA study of an SKF manufacturing line.We demonstrate how system boundaries and functional units in an LCA can be defined when adding the perspective of a manufacturing decision maker to the product life-cycle perspective. Such analysis helps manufacturing decision makers identify improvement potentials in their spheres of influence, by focusing on the environmental consequences of energy and material losses in manufacturing rather than merely accounting for the contributions of individual stages of the life cycle to the overall environmental impact. The method identifies and directly relates the environmental consequences of emissions or raw material inputs in the product life cycle to manufacturing processes. In doing so, the holistic systems perspective in LCA is somewhat diminished in favor of the relevance of results to manufacturing decision makers.  相似文献

Climate governance in Small Island developing States (SIDS) is a pressing priority to preserve livelihoods, biodiversity and ecosystems for the next generations. Understanding the dynamics of climate change policy integration is becoming more crucial as we try to measure the success of environmental governance efforts and chart new goals for sustainable development. At the international level, climate change policy has evolved from single issue to integrated approaches towards achieving sustainable development. New actors, new mechanisms and institutions of governance with greater fragmentation in governance across sectors and levels (Biermann and Pattberg, 2008) make integration of policy in the area of climate change governance even more of a challenge today. What is the Caribbean reality regarding policy coherence in climate change governance? Are the same climate change policy coherence frameworks useful or indeed applicable for environmental governance in developing states more generally and for SIDS in particular? What are the best triggers to achieve successful climate change policy integration in environmental governance—especially as the complex interconnectivity of new actors, institutions and mechanisms make the process of integration even more challenging? What facilitates and what hampers climate policy integration in the regional Caribbean context? This article reviews the debates around policy coherence for climate change governance, creates a framework to test or measure policy coherence and examines how relevant this has been to regional climate change governance processes in Commonwealth Caribbean States. The study found that though at the regional level, there is substantial recognition of the importance of and mechanics involved in climate policy coherence, this has not translated to policy coherence at the regional and national levels. There is a large degree of fragmentation in the application of climate policy in each Caribbean Island with no mechanism to breach the gap. Silos in public environmental governance architectures, unwillingness to share data, insufficient political will; unsustainable project-based funding and lack of accountability among actors are the main challenges to climate policy coherence. The findings fill a gap in the literature on the elements of climate policy coherence from a SIDS perspective.  相似文献

Biodiversity conservation “area-selection” strategies include not only trade-offs among society’s needs in land-use allocation, but also allocation of economic instruments such as incentives, levies, and biodiversity credits. For these applications, the key property of an area is its “complementarity”—the context-dependent, marginal gain in biodiversity provided by the area. Given that there has been little implementation of whole-sets of areas generated by the popular computer-based selection methods, we suggest that analogous “policy-based algorithms” would be a more effective real-world application of complementarity. Areas would be “selected” for conservation over time as a consequence of policies in which dynamic complementarity values influence application of economic instruments. These integrated biodiversity/economic strategies can use an extended form of complementarity reflecting marginal changes in regional probability of persistence of biodiversity. While probabilistic measures of biodiversity viability have been explored in area-selection for some time, it remains difficult to make viability statements about “all of biodiversity.” New approaches that use biodiversity surrogate information for “biodiversity viability analysis” (BVA) can take advantage of a general quantitative biodiversity framework in which pattern-based relationships among areas allow predictions at the species level. A standard assumption of “unimodal” species responses to environmental gradients yields an expected distribution of species in an ordination pattern, and allows sampling of inferred species. Based on environmental correlates, inferred species can be mapped in geographic space, forming distribution fragments. This information, when linked to species persistence models, may allow ongoing calculation of areas’ complementarity values. An example illustrates application of these ordination models to museum collection data for lizards from New South Wales (NSW), Australia.  相似文献

Responding to global change represents an unprecedented challenge for society. Decision makers tend to address this challenge by framing adaptation as a decision problem, whereby the responses to impacts of change are addressed within existing decision processes centred on defining the decision problem and selecting options. However, this ‘decision-making perspective’ is constrained by societal values and principles, regulations and norms and the state of knowledge. It is therefore unsuitable for addressing complex, contested, cross-scale problems. In this paper we argue that simply broadening the decision-making perspective to account for institutions and values is not enough. We contend the decision-making perspective needs to be connected with a broader ‘decision-context perspective’ that focuses on how the societal system of decision processes affects the manner in which a particular problem is addressed. We describe the decision context as an interconnected system of values, rules and knowledge (vrk). The interaction of systems of vrk both creates and limits the set of practical, permissible decisions; the types of values, rules and knowledge that influence the decision and the capacity for change and transformation in the decision context. We developed a framework to analyse the interactions between values, rules and knowledge and their influence on decision making and decision contexts of adaptation initiatives, and applied it retrospectively to three projects on adaptation to sea-level rise. Our analysis revealed: (1) specific examples of how interactions between vrk systems constrained existing framings of decision making and the development of options for coastal adaptation; (2) limitations in the adaptive management strategies that underpinned the projects and (3) how the linked systems of vrk can allow adaptation practitioners to structure adaptation as a process of co-evolutionary change that enables a broader set of social issues and change processes to be considered. Adaptation projects that focus on the decision context represent a pragmatic alternative to existing decision-focused adaptation. By using the vrk model to diagnose constraints in decision processes, we show how the reframing of adaptation initiatives can reveal new approaches to developing adaptation responses to complex global change problems.  相似文献

The concerns over climate change negotiation, decision texts and links to domestic policy interests of countries to keep warming within an acceptable limit have become the ‘hotspot issues’ of the United Nations Framework Convention on Climate Change (UNFCCC). Hotspot issues are the human – political economy factors which have evolved over time from negotiation texts or phrases, principles or behaviors with tendencies to influence climate negotiations yet cannot be identified with the scientific literature. Whilst big emitters have been accused as having hegemony over the negotiations, the effects of disunity amongst the parties over domestic policy interests have been overlooked. Hence the article examines the emergence of hotspot issues and how they manifest within the international climate policy regime. The Intended Nationally Determined Contributions (INDCs) of 130 countries submitted before the Paris agreement, were analyzed using the following texts: Adaptation, Mitigation, Co-benefits, Finance, Land use, Food security, Poverty, Resilience, Green growth, Green economy, Sustainable development, Biodiversity, Ecosystem services and Conservation. Of these, ‘adaptation’ was cited 2780 times, 1956 for ‘mitigation’ and 32 for ‘ecosystem services’ in the nature conservation category. Ten phases of the climate policy regime and historical hotspot issues were identified for the period 1980–2030. ‘Adaptation’ and mitigation appeared more frequently in the INDCs and correlated with each other (r = 0.56), as the two correlated further with ‘land use’ (0.50 < r < 0.60), and similarly with sustainable development (0.40 < r < 0.70) where ‘r’ is the Pearson Rank Correlation. Therefore the success of the ‘ambitious targets’ for mitigation will depend on similar ambitious goals for adaptation, land use and sustainable development. Several differences existed in the correlation of the hotspot issues within the regional geographical blocs (Africa, Asia, Europe, North America, Oceania, South America) and split along the hotspot issues yet Europe mostly oriented towards mitigation and land use, and Oceania on resilience building. These differences provide favorable conditions for increased cooperation and true multilateralism if they are properly diagnosed.  相似文献

‘Design for Remanufacture’ or DfRem, is an area of remanufacturing research that has received relatively high levels of interest in recent years, due to the recognition that a product’s design may have a high impact on remanufacturing efficiency. However, the overall volume of literature dedicated to DfRem is low and there is still much to learn about the subject. The purpose of this literature review is to collate the current body of literature and establish a contemporary understanding of DfRem through analysing the trends, agreements and conflicts of opinion in the field. Much of the DfRem literature to date is focused upon the investigation of remanufacturing problems associated with product design, and the subsequent development of design methods and tools, either specifically developed to aid DfRem or as adaptations of existing design methods. These methods and tools vary in purpose and intended use but all largely remain within the academic realm to date. Within the literature there is widespread agreement that any approach to DfRem must consider both product and process, yet the ‘design for X’ definition of the task continues to spark debate. The key problems and issues that future DfRem research should address have been identified in this paper, from both within the literature and from the current gaps in the literature. Some key recommendations for future research include the need for ‘lifecycle thinking’ within design method development and the need for greater exploration into the organisational factors affecting DfRem integration into the design process, from the perspectives of the OEM and designer.  相似文献

As part of the inquiry into managing an interdisciplinary research process on adaptive water governance, we investigated the process of group model building (GMB) and, more specifically, the role of Unified Modeling Language (UML) in this process. An analysis of group interaction reveals several tensions in the process of knowledge integration, which can be grouped into three overarching dualities: ‘simplicity versus complexity’, ‘constraining versus containing’ and ‘defining versus refining’. As group members take different positions with regard to these dualities, these represent sources of tension and potential ‘stuckness’ of the GMB. Hence the question arises how the group can manage duality in ways that take the GMB beyond its opposing forces. We suggest that knowledge integration processes may benefit from early recognition of the dualities at hand and strategies aimed at creating ‘thirdness’, including some suggestions on the concrete forms such ‘thirdness’ may take.  相似文献

We present a method how to estimate and compare the cooperative behavior of countries within the international climate change regime. Two indicators measure whether and how fast countries have committed to the United Nations Framework on Climate Change (UNFCCC) and the Kyoto Protocol (KP). Three additional indicators quantify whether and how effectively measures have been implemented in line with these agreements. These three measures are reporting, financial contributions, and development of per capita CO2 emissions in relation to the per capita gross domestic product of each country. Results show that developed countries with emission targets under the KP ratified the protocol more often and faster, submitted their report timelier, and paid their annual financial contributions to the UNFCCC secretariat more regularly than the other countries. However, concerning CO2 emissions, developing countries are evaluated more positively than developed countries. The five indicators are aggregated to a ‘Cooperation Index’ that evaluates 198 countries’ cooperative behavior within the international climate regime on a scale between 0 (=least cooperative) and 6 (=most cooperative). According to this Cooperation Index, the following large countries are ranked after their level of cooperation in ascending order: United States of America, Australia, Russia, Canada, Brazil, China, India, South Africa, and large European countries.  相似文献
