Integration of environmental science in society is impeded by the large gap between science and policy that is characterised by weaknesses in societal relevance and dissemination of science and its practical implementation in policy. We analyse experiences from BONUS, the policy-driven joint Baltic Sea research and development programme (2007–2020), which is part of the European Research Area (ERA) and involves combined research funding by eight EU member states. The ERA process decreased fragmentation of Baltic Sea science and BONUS funding increased the scientific quality and societal relevance of Baltic Sea science and strengthened the science-policy interface. Acknowledging the different drivers for science producers (academic career, need for funding, peer review) and science users (fast results fitting policy windows), and realising that most scientists aim at building conceptual understanding rather than instrumental use, bridges can be built through strategic planning, coordination and integration. This requires strong programme governance stretching far beyond selecting projects for funding, such as coaching, facilitating the sharing of infrastructure and data and iterative networking within and between science producer and user groups in all programme phases. Instruments of critical importance for successful science-society integration were identified as: (1) coordinating a strategic research agenda with strong inputs from science, policy and management, (2) providing platforms where science and policy can meet, (3) requiring cooperation between scientists to decrease fragmentation, increase quality, clarify uncertainties and increase consensus about environmental problems, (4) encouraging and supporting scientists in disseminating their results through audience-tailored channels, and (5) funding not only primary research but also synthesis projects that evaluate the scientific findings and their practical use in society – in close cooperation with science users − to enhance relevance, credibility and legitimacy of environmental science and expand its practical implementation. 相似文献

This paper highlights some recent trends and developments in dialogue on radioactive waste management in the UK. In particular, it focuses on the use of dialogue around options for the management of risk, and describes techniques for stakeholder dialogue in the field of radioactive waste management. The paper summarises past and on-going experience in the UK, and provides an overview of some practical examples from decommissioning of the former reprocessing facility at Dounreay in Scotland. In common with developments and trend in other countries, the UK has moved to a position where there is now widespread recognition that radioactive waste management requires not only sound technical assessment of risk, but also public participation, consultation and stakeholder dialogue on proposed solutions and the associated risks. In fact, the shift of position has arguably been quite pronounced, with formal procedures to identify, clarify and integrate stakeholders' issues and concerns within the decision-making processes. Experience suggests that citizens are capable of engaging with complex technical issues such as radioactive waste. Indeed, the earlier in the decision-making process that public and stakeholder engagement (PSE) occurs--for example, on the consideration of options and alternatives--the greater the chance of reaching a successful outcome that properly reflects the values and opinions of stakeholders. In the UK, the assessment of alternative waste management options is increasingly being addressed through Best Practical Environmental Option (BPEO) studies. Responses to stakeholder engagement processes and experience of conducting BPEO studies emphasise that consultation must be open, transparent, deliberative and inclusive. However, while early consideration of generic approaches and option choices is necessary to generate a climate of openness and understanding, it remains essential to fully engage with local stakeholder and community groups to consider issues associated with proposed developments at a site-specific level. An interesting area where further attention may be warranted is the use in final decision-making of the results from participatory processes such as BPEO studies. Demonstrating clearly that participants' views have influenced decisions appears to be essential for retaining legitimacy and trust, confidence and goodwill. 相似文献

Within the emerging concept of industrial ecology (IE) that belongs to the research and practical field of sustainable development (SD), the natural ecosystem evolution over time has been described as a metaphor that presents systems of type I, type II and type III ecology. Type I describes a situation when there was little life on earth and plenty of resources. In type II, the ecosystem starts to develop material cycles and energy cascades between organisms and species due to increasing amount of life and emerging scarcity of resources. In type III, the mature ecosystem stage, the system actors have developed nearly completely cyclic flows of matter, energy cascades and diverse interdependencies between them. This paper uses the metaphor in the three systems to develop practical models of type I, II and III industrial ecosystems for an economic system of heating energy and its evolution over time. First, the physical flows of matter and energy are described by using two contrasting case system characteristics, 'throughput' and 'roundput'. Throughput means linear material and energy flows. Roundput means material cycles, energy cascades and sustainable use of renewables, i.e., ecosystem type III. Second, the more structural and organisational features are considered with the characteristic of 'diversity' meaning diversity in resources, human involvement and economic actors and technology used. The case system development over time shown with our practical model of type I–III is radically different from the ecosystem evolution as described in the literature on the industrial ecosystem metaphor of type I–III. This conclusion as a research result, however, is tentative, because of the fuzzy and vague meaning assigned to a metaphor and its confusion with a practical model of industrial development in the industrial ecology literature. 相似文献
