This paper concisely introduced the eco-environmental survey in China and the Chinese scientific programme for environmental research which is being practiced or being planned. China has established a nation-wide system relating to environmental scientific research and environmental administration and has taken the following strategies for solving the environment problems: (1) a series of laws and regulations for environmental protection has been promulgated so as to strengthen the legal administration and economic punishment. (2) the idea of ecological construction has been proposed for the purpose of taking the environmental protection work into the consideration of the national and provincial (or regional) economic construction planning. (3) spreading ecological engineering and ecological technologies have reduced the pollutant sources and have increased the industrial and agricultural economic profit.  相似文献

Implementation of current environmental and natural resource policy has created an era of regulatory discontent, and has prompted calls for new approaches to management that can achieve both long-term ecological sustainability and improved policy performance. These new approaches, such as ecosystem management, emphasize the importance of holistic and integrated science, meaningful public involvement to reflect changing societal goals and objectives, collaborative decisionmaking, and flexible and adaptable institutions. Implementing such approaches will require significant institutional change in all institutions, including the institution of science. Attributes of the scientific culture — including adherence to the myth of objective, value-free science, preference for technical solutions as first-order solutions, and advancement of the scientific method and scientific rationality as preferred logic — have often worked to separate scientists from citizens and science from the policymaking process. They have also fostered undemocratic processes and results. Changes in the institution and culture of science, including embracing more holistic and integrated scientific processes, creating a more civic science, and rethinking the role of scientific advocacy in the policy process, will be required to move toward democratic as well as ecological sustainability.  相似文献

Over the last 10 years the UK Government has strongly promoted the more effective use of science to inform policy-making and regulation. In response, the Environment Research Funders’ Forum (which brings together the main UK Governmental funders of environmental research) has carried out studies, reported in this paper, to establish what is working, what is not, and why in respect of the linkage between science and environmental policy-making and regulation.The findings indicated that there was potential to improve effectiveness in: establishment of research questions and agendas, accessing information and expertise, the role of interpreters, and transparency and evaluation. These findings are re-enforced by those of previous studies conducted in the UK and EU. The studies found that current practice in using science to inform policy-making has not yet caught up with guidance, and they identified potential actions that could be taken by the Forum and its members to narrow the gap.  相似文献

As lay publics demand a greater role in the environmental and health decision-making that impacts their lives, policy makers are being forced to find new ways of understanding and incorporating the expertise of professionals with the contextual intelligence that community residents possess. This paper highlights how co-producing science policy, where technical issues are not divorced from their social setting and a plurality of participants engage in everything from problem setting to decision-making, can contribute to more scientifically legitimate and publicly accountable decisions. Through a detailed case study utilizing participant observation, ethnographic field work, semi-structured interviews, and reviews of original documents, this paper highlights how residents in a low income, Latino immigrant neighborhood in New York City organized their knowledge to participate in and significantly alter a U.S. Environmental Protection Agency exposure assessment. This paper reveals both the contributions and limits of local knowledge in environmental health governance and how the co-production framework can contribute to more technically credible science and democratically accountable policy.  相似文献

Given the proliferation of primary research articles, the importance of reliable environmental evidence reviews for informing policy and management decisions is increasing. Although conducting reviews is an efficient method of synthesising the fragmented primary evidence base, reviews that are of poor methodological reliability have the potential to misinform by not accurately reflecting the available evidence base. To assess the current value of evidence reviews for decision-making we appraised a systematic sample of articles published in early 2015 (N = 92) using the Collaboration for Environmental Evidence Synthesis Assessment Tool (CEESAT). CEESAT assesses the methodology of policy-relevant evidence reviews according to elements important for objectivity, transparency and comprehensiveness. Overall, reviews performed poorly with a median score of 2.5/39 and a modal score of zero (range 0–30, mean 5.8), and low scores were ubiquitous across subject areas. In general, reviews that applied meta-analytical techniques achieved higher scores than narrative syntheses (median 18.3 and 2.0 respectively), as a result of the latter consistently failing to adequately report methodology or how conclusions were drawn. However, some narrative syntheses achieved high scores, illustrating that the reliability of reviews should be assessed on a case-by-case basis. Given the potential importance of reviews for informing management and policy, as well as research, it is vital that overall methodological reliability is improved. Although the increasing number of systematic reviews and meta-analyses highlight that some progress is being made, our findings suggest little or no improvement in the last decade. To motivate progress, we recommend that an annual assessment of the methodological reliability of evidence reviews be conducted. To better serve the environmental policy and management communities we identify a requirement for independent critical appraisal of review methodology thus enabling decision-makers to select reviews that are most likely to accurately reflect the evidence base.  相似文献

Public ecology exists at the interface of science and policy. Public ecology is an approach to environmental inquiry and decision making that does not expect scientific knowledge to be perfect or complete. Rather, public ecology requires that science be produced in collaboration with a wide variety of stakeholders in order to construct a body of knowledge that will reflect the pluralist and pragmatic context of its use (decision context), while continuing to maintain the rigor and accountability that earns scientific knowledge its privileged status in contemporary society. As such, public ecology entails both process and content. The process is that of a post-modern scientific method: a process that values the participation of extended peer communities composed of a diversity of research specialists, professional policy-makers, concerned citizens and a variety of other stakeholders. The content of public ecology is a biocultural knowledge of dynamic human ecosystems that directly relates to and results from the participatory, democratic processes that distinguish public ecology as a citizen science. The primary goal of public ecology is to build common ground among competing beliefs and values for the environment. The purpose of this paper is to help unify and establish public ecology as a distinctive approach to environmental science and policy in global society.  相似文献

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
