Theory suggests that the influence of science on policy will be greater when scientific discourse is aligned with the language and meaning of wider social concerns. Seeking to assess whether scientists may be guided by such propositions in a controversial environmental policy arena, we examine the language and content of public-facing, UK scientific research grant abstracts on biofuels for the period 2007–2011, comparing these to stakeholder position statements and newspaper articles of the same period. We find that UK scientists have indeed broadly reflected societal concerns about biofuels during this period. However we also find that both science and society have paid less attention to procedural issues. We comment on the implications of the findings for the role of science in environmental policy development.  相似文献

Climate scenarios serve a number of functions in helping society manage climate change—pedagogic, motivational or practical (for example, in engineering design, spatial planning and policy development). A variety of methodologies for scenario construction have been experimented with, all of them to a greater or lesser extent depending on the use of climate models. Yet the development of climate scenarios involves much more than climate modelling. The process of scenario development is one of negotiation between relevant stakeholders—funding agencies, policy communities, scientists, social actors and decision-makers in a variety of sectors. This process of negotiation is illustrated through an analysis of four generations of UK climate scenarios—published in 1991, 1996, 1998 and 2002. Using ideas from science and technology studies and the sociology of scientific knowledge to guide our analysis, we reveal complex relationships between the interests of UK science, policy and society. Negotiating climate scenarios involves compromise between the needs of policy, science and decision-maker in relation to, for example, the selection of the development pathway(s) and emissions scenario(s), the choice of climate model(s), the assessment and communication of uncertainty and the presentational devices used. These insights have a significant bearing on the way in which climate scenarios should be viewed and used in public discourse, strategic planning and policy development.  相似文献

We propose a suite of actions for strengthening water governance in contexts with complex, multi-tiered arrangements. In doing so, we focus on the collective water policies and approaches of the United Kingdom (UK), including those of devolved governments, which confront a host of serious water-related challenges—from massive flooding of urban areas and agricultural lands, to pressure on aquifers from rising water demand and drought. Further complexity in addressing these challenges has emerged in the wake of the June 2016 vote to leave the European Union (EU), so-called ‘Brexit’, and the ensuing ‘separation process’ with uncertainties for institutional and governance arrangements to follow. We make ten proposals for improving and reinvigorating water policy in complex, multi-layered situations, and comment specifically on their application in the UK setting. These are: put in place a system-wide water policy; fully embrace community-led nested river basin planning and management; fully fund river basin planning and management; re-focus the policy framing; use best-available data and information; create conversational spaces and become a more water-literate society; mobilise people; support and sustain core community networks; underpin river basin plans with regulatory provisions and effective monitoring and enforcement; and address systemic institutional amnesia. Individually and collectively, we contend that these actions will have a marked effect on transforming the planning and management of water resources. A system-wide water policy that maintains and builds on the substantive biophysical and socio-economic benefits delivered through implementation of the EU Water Framework Directive, together with the more recent Floods Directive, will galvanise stewardship of water in the UK. We urge more active engagement with and empowerment of the multiplicity of system ‘actors’, and highlight the role of non-government actors in a post-Brexit world as conduits for reaching out to and connecting directly with a wide range of water-related actors, especially across the EU. While attention to-date has focused on a plethora of specifically water-related projects, initiatives, plans and regulations, what is really needed is a systemic, long-term view of water resource management.  相似文献

Climate change science can trace its origins back to the early 19th Century although interest really took off in the 1980s, when public interest and research activity proliferated as the potential negative effects of global warming became clear. The impacts of climate change on the marine environment was receiving little attention at this time, but in recent years has started to “catch up” both in terms of research activity and public and policy interest. In the UK, the Marine Climate Change Impacts Partnership (MCCIP) has played a key role in transferring the emerging evidence base on marine climate change impacts to decision makers through the development of climate change report cards. Since publishing its first card back in 2006, the MCCIP cards have become established as the principal source of marine climate change impacts evidence for policy makers in the UK, and similar approaches have been adopted elsewhere. Here we broadly describe how the climate change evidence base has evolved over time, with a focus on the marine evidence base, and the approach adopted in the UK by MCCIP to rapidly transfer this evidence to end users. The SIIRMS model developed by MCCIP to ensure integrity and independence in the scientific translation process is explored, along with wider lessons learnt along the way (e.g. about communicating uncertainty) and the impact MCCIP has had on informing decision making.  相似文献

农田生态补偿政策是采用经济手段激励农户对农田生态系统服务功能进行保育和维护,解决因市场失灵造成生态效益外溢的一种有效方式,对于改善农田生态环境、提升农地开敞空间、增加农户收益具有积极作用。论文从发达地区农户生计多样性角度入手,利用结构方程模型分析农户生计多样性对农户参与补偿政策的支持意愿、政策实施效果响应的影响。结果表明:①农户基本特征、家庭特征、生计多样性特征、村庄发展特征在5%的水平下对农户在农田生态补偿政策上的支持意愿具有正向影响;②农户基本特征、家庭特征、生计多样性特征在5%的水平下对农户在补偿政策实施效果上的响应具有正向影响,农户村庄发展特征在5%的水平下对其具有负向影响;③农户生计多样性特征是影响农户补偿政策支持意愿最主要的因素,是影响补偿政策实施效果响应的次要因素。这表明补偿政策实施后,农户生计多样性特征对于提高农户对补偿政策支持意愿与政策实施效果响应方面具有积极的作用。把握三者之间的关系有利于政府制定和完善现有农田生态补偿政策,为引导农户生计多样性发展提供参考。  相似文献

Understanding how environmental policy decisions were reached in the past might help predict policy development in the future. This paper evaluates how well two existing frameworks for decision analysis fit acid rain policy development of the UK Central Electricity Generating Board (CEGB) in the 1980s. Decision tree analysis assumes a rational approach to decision-making and overlooks the dynamic nature of the decision making process. Trudgill's model identifies barriers to policy development, but it is not possible to identify which are most important. Both concentrate on the role of scientific uncertainty in the acid rain debate. An alternative approach is presented which identifies all possible influencing factors and assesses their relative influence. Whilst confirming the importance of the resolution of scientific uncertainty in this case study, it identifies a number of alternative pressure sources, including independent scientific review, rises in SO2 emissions, European environmental legislation, and influences within the Government. In all three models, ascribing predictive values to all possible options is a major problem. All models are limited in their ability to describe complex and dynamic environmental problems, and hence have limited predictive powers. Decision tree analysis and Trudgill's barriers model identify how scientific uncertainty is dealt with within organisations, whilst the influencing factors approach puts decisions in a broader, political framework.  相似文献

Reducing emissions from deforestation and forest degradation (REDD+) is receiving increasing political and scientific attention as a climate change mitigation approach. The government of Cameroon has expressed an interest in participating in REDD+, and national deliberation on a policy strategy has attracted interest from different actors in the forest sector. This paper analyses the challenges of designing a governance structure for a REDD+ strategy in Cameroon. Theoretically, the paper builds on the literature on governance structures for resource management, focusing analytically on the interactions between actor constellations (state and non-state) and institutions (formal and informal) to produce policy outcomes. The paper draws on documentation of REDD+ policy events, policy texts and 23 in-depth interviews with members from government, civil society, research organizations, development partners and the private sector. It argues that although the actors involved in REDD+ are, to an extent, polarized around different issues and priorities, they are nonetheless increasingly distributing roles and responsibilities among themselves. The institutional arrangements within the policy process include: (1) rule-making systems for engagement; (2) expanding existing coordination mechanisms; (3) national safeguard standards; and (4) building on existing forest governance initiatives. The paper concludes that the multiple benefits promised by REDD+, such as poverty alleviation, biodiversity conservation and economic development, are critical for the legitimacy of the mechanism.  相似文献

As the EU-wide Water Framework Directive enters into public policy, the UK faces significant challenges in managing its water resources, including exceptional flood and drought events in recent years. New legislation is resurfacing existing conflicts and generating new debates among multiple stakeholders about managing water catchments. Existing policies and practices are under strain as a result. This paper reports how the SLIM project in the UK researched the role of a systemic approach to managing multiple perspectives and stakeholding in water catchments and the new challenges this presents to existing forms of knowledge and practice. The authors apply the conceptual tradition of systems thinking and practice, and the methodological approach of systemic co-researching inquiry to empirical studies in the Tweed, the Ythan, and the Eye Brook catchments, in the context of a review of policy and practice in the UK. The extent to which systems approaches to multiple stakeholding can lead to social learning for concerted action is considered. An assessment of the implications of the research findings for policies and practices in managing water catchments concludes the article.  相似文献

In modern society, science is considered to have a pivotal role in defining environmental risks and problems as well as proposing relevant solutions to them. However, even political action is needed, which is not the least apparent when it comes to transboundary environmental problems. Today, there is an urgent need to create ways for science and policy to co-operate to find acceptable international solutions to transboundary environmental problems.This article focuses on the relationship between science and policy within the convention on long-range transboundary air pollution (CLRTAP). The LRTAP convention is seen as one of the most science-based regimes that exist, and is considered by researchers as well as politicians an exemplary form of co-operation between science and policy. Within this convention the concept of critical loads (CL) of ecosystem and the interactive computer model of the regional acidification information system (RAINS) have served as important tools for connecting scientific knowledge to policy-making. Through an empirical investigation, the article shows that CL and RAINS have different meanings for the involved actors, which include heterogeneous views on the boundary between science and policy. However, this has not constrained but rather enabled co-operation. Through a flexible understanding of CL and RAINS, actors from different fields have been able to find and agree upon successful solutions.  相似文献

There has been resurgence in interest in new nuclear power stations over the last couple of years. The UK Government has taken steps to encourage the private sector to build new stations in the UK, a change in its previous neutral stance toward nuclear power. This paper examines the change in government policy asking what drivers have led to this decision and what barriers were preventing new nuclear power in the past and what barriers are still faced by both government and industry. Three main drivers are discussed: security of energy supply; diminishing energy generation capacity; and climate change. The paper also examines other key factors that play a part in facilitating a shift in government policy, namely economics, public perception and waste management policy. Barriers are identified through examination of public perception, and policy. The changes to the planning system are also discussed. The paper concludes by comparing drivers and barriers for other technologies and contrasting the UK experience with that of other countries.  相似文献

Biodiversity is under threat from anthropogenic pressures, in particular in biodiversity-rich developing countries. Development cooperation actors, who traditionally focus on the improvement of socio-economic conditions in the South, are increasingly acknowledging the linkages between poverty and biodiversity, e.g. by referring to the ecosystem services framework. However, there are many different framings which stress the need for biodiversity integration and which influence how biodiversity and development are and/or should be linked. Moreover, there is a gap between the lip service paid to biodiversity integration and the reality of development cooperation interventions. This study analyses how biodiversity framings are reflected in environmental impact assessment (EIA) practice, and how these framings influence EIA and decision-making. The findings, based on an in-depth qualitative analysis of World Bank EIAs undertaken in West Africa, indicate the incoherent quality but also the dominance of the ‘utilitarian’ and ‘corrective’ framings, which respectively stress human use of nature and mitigation of negative unintended development impacts. Identifying and highlighting these discursive trends leads to increased awareness of the importance of biodiversity among all development actors in North and South. However, some framings may lead to an overly narrow human-centred approach which downplays the intrinsic value of biodiversity. This study proposes recommendations for an improved integration of biodiversity in development cooperation, including the need for more systematic baseline studies in EIAs.  相似文献

This paper reviews the factors influencing the development and sustained operation of regional industrial symbiosis (IS) networks and discusses the roles a coordination body can play to alter these factors so as to catalyse the development and functioning of such networks. These are analysed within the context of experiences gained in the early stages of three regional IS programmes under development in the UK, and of the recently launched national IS programme (NISP) that they are part of. It is stated that the policy framework in the UK has elements supportive of such networks to evolve, and the regional public bodies are favouring their development. Based on differences among studied cases, it is argued that the nature of companies’ operations and industrial history in the regions, the extent of peer pressure, the positioning of the coordinating body in the region, and its approach to awareness raising and recruitment have major influence on the progress of the programmes. Finally, the paper emphasises the importance of aligning the characteristics of emerging operations with the longer-term sustainability requirements. If accepted, this challenge assigns additional responsibilities to the coordinating parties.  相似文献

Challenges for a sustainable urban development are increasingly important in cities because urbanization and related land take come up with negative challenges for the environment and for city residents. Searching for successful solutions to environmental problems requires combined efforts of different scientific disciplines and an active dialogue between stakeholders from policy and society. In this paper, we present a comparative assessment of the way policy-science dialogues have achieved knowledge co-production about strategic urban environmental governance action using the cities of Berlin in Germany and Rotterdam in the Netherlands as case studies. The ecosystem services framework is applied as a lens for policy–science interaction and a ‘knowledge co-production operating space’ is introduced. We show how policy officers, urban planners, practitioners and scientists learned from each other, and highlight the impact of this knowledge co-production for governance practice. We found that the concerted collaboration and co-creation between researchers and policy officers have led to mutual learning and establishment of relationships and trust in both cities. Not only the policy-relevance of research and its policy uptake were achieved but also new insights for research blind spots were created. In our conclusions we reflect on co-production processes with two types of conditions that we introduced to be most influential in the way knowledge can be co-created. These are conditions that relate to the way knowledge co-production processes are set-up and, conditions that relate to the expected value or benefit that the co-produced knowledge will bring across society, policy and practice.  相似文献

In light of the theoretical implications from ecological economics and industrial ecology, increased efforts should be undertaken by policy makers to make consumption “reasonable”. To remain sustainable, “reasonable” decisions should take into account the long-term survival of ecosystem and acknowledge the fact that the existence of human species ultimately depends on it. Two additional objectives should complement “reasonable” consumption: (1) changing product systems so that products are properly managed at the end of their useful lives. (2) making products more environmentally friendly. A case study of the Integrated Product Policy of the European Union reveals that it addresses the above objectives selectively. The general conclusions are that “reasonable” behaviour is challenged by conflicting interests of various market actors, that economic reasoning should complement environmentally “reasonable” behaviour, and that “reasonable” consumption should indeed be discussed in conjunction with “reasonable” production.  相似文献

水电开发对河流生态系统的影响不容忽视,科学评估其影响有助于建立更可持续的水电开发模式。以武江干流为例,利用当量因子法和功能价值评估法,分析了武江干流梯级水电开发对受淹没影响的河岸带陆地生态系统和河流生态系统服务的效益及损失,并就其对河流生态系统服务的综合效应进行了评估。结果显示:武江干流水电开发使受淹没影响的河岸带生态系统和河流生态系统本身的服务价值均出现增加,价值增量主要体现在水文调节、水资源供给等服务方面;武江干流水电开发对河流生态系统服务的正效应大于负效应,正效应主要体现在发电、水文调节、气体调节等方面,负效应主要体现在维持生物多样性、土壤保持等支持服务方面。研究认为不同规模水电站的正负效应侧重点不同,不同流域单位电能的生态损失难以直接横向比较。结合多年来武江鱼类资源跟踪调查数据,分析了鱼类生物损失指数的变化趋势,探讨了水电开发在时间上的累积生态效应及水电服务的空间格局差异。由于生物多样性等服务的影响难以用货币直接衡量,加上水域的单位面积服务价值远高于其他生态用地类型,导致负效应的价值评估偏保守,武江干流水电开发的正负效应之比偏大。  相似文献

This article explores how science and policy interact using the Norwegian Red List 2006 as a case example. The paper draws on concepts from the sociology of science, interviews with key informants, as well as analysis of a Norwegian newspaper debate about a controversial conservation issue.The paper highlights how the relationship between science and policy can best be described as an interaction rather than simply a transmission of knowledge from one to the other. In addition, the study focuses on the active construction and communication of the science–policy relationship. Regulators, scientists and NGOs, it is argued, strategically define the relationship between science and policy as more straightforward than it really is.The paper suggests that the shaping, simplification and communication of scientific knowledge is best understood as a social process that occurs in three stages, which may overlap to varying degrees. The shaping of scientific knowledge for policy occurs first within the scientific domain. The shaping, we suggest, is the result of both the broader institutional context and a more specific micro-level social context, but it is also the outcome of requirements inherent in the genre of science communication. In the second stage, regulators and actors in the public debate redefine and simplify scientific knowledge to make it better suited to the policy arena. In the final stage, scientists, regulators and NGOs actively seek to define science as objectively true, and independent of the policy arena. By doing so, they are able to strengthen their arguments, regardless of their position on particular issues. But they also contribute to shrouding the social nature of scientific production.  相似文献
