Daniel Bromley argues against Oran Young’s FIT model as a basis for environmental governance, on the grounds that humans cannot manage nature and that attempts to do so are based on a scientistic, modernist conceit. At issue is the role of natural and social scientists in adjudicating questions about what we ought to do to close governance gaps and address unsustainable behaviors. If Bromley is right, then the lessons of the American pragmatist tradition recommend against attempts to “fit” social institutions to the natural world. The first objective of this paper is to argue that Bromley’s view is not in keeping with the pragmatism of C. S. Peirce and John Dewey, which actually places a high value on natural and social scientific modes of inquiry in the service of social ends. I argue that Young’s proposal is in fact a development of the pragmatist idea that social institutions must be fit in the sense of fitness, i.e., resilient and able to navigate uncertainty. Social institutions must also evolve to accommodate the emerging values of the agents who operate within them. The second objective of this paper is to examine the role of social science expertise in the design of social policies. Governance institutions typically rely on the testimony of natural scientists, at least in part, to understand the natural systems they operate within. However, natural systems are also social systems, so it seems pertinent to ask whether there is a role for social systems experts to play in helping to design environmental governance institutions. I argue that social scientists can make a unique contribution as experts on social institutions, and as such, are necessary to bring about a transformation of the unsustainable institutions that are preventing us from achieving stated sustainable development goals.

The content for the school science curriculum has always been an interplay or contest between the interests of a number of stakeholders, who have an interest in establishing it at a new level of schooling or in changing its current form. For most of its history, the interplay was dominated by the interests of academic scientists, but in the 1980s the needs of both future scientists and future citizens began to be more evenly balanced as science educators promoted a wider sense of science. The contest changed again in the 1990s with a super-ordinate control being exerted by government bureaucrats at the expense of the subject experts. This change coincides with the rise in a number of countries of a market view of education, and of science education in particular, accompanied by demands for public accountability via simplistic auditing measures. This shift from expertise to bureaucratise and its consequences for the quality of science education is illustrated with five case studies of science curriculum reform in Australia.

This article compares the cases of ozone layer protection and climate change. In both cases, scientific expertise has played a comparatively important role in the policy process. The author argues that against conventional assumptions, scientific consensus is not necessary to achieve ambitious political goals. However, the architects of the Intergovernmental Panel on Climate Change operated under such assumptions. The author argues that this is problematic both from a theoretical viewpoint and from empirical evidence. Contrary to conventional assumptions, ambitious political regulations in the ozone case were agreed under scientific uncertainty, whereas the negotiations on climate change were much more modest albeit based on a large scientific consensus. On the basis of a media analysis, the author shows that the creation of a climate of expectation plus pressure from leader countries is crucial for success. © 2006 Sage Publication.

In present day knowledge societies political decisions are often justified on the basis of scientific expertise. Traditionally, a linear relation between knowledge production and application was postulated which would lead, with more and better science, to better policies. Empirical studies in Science and Technology studies have essentially demolished this idea. However, it is still powerful, not least among practitioners working in fields where decision making is based on large doses of expert knowledge. Based on conceptual work in the field of Science and Technology Studies (STS) I shall examine two cases of global environmental governance, ozone layer protection and global climate change. I will argue that hybridization and purification are important for two major forms of scientific expertise. One is delivered though scientific advocacy (by individual scientists or groups of scientists), the other through expert committees, i.e. institutionalized forms of collecting and communicating expertise to decision makers. Based on this analysis lessons will be drawn, also with regard to the stalling efforts at establishing an international forestry regime.

There is clearly contention over the shape and formation of science curriculum and over, ultimately, what will count as scientific knowledge, skill, capacity and world view. The Cold War set the policy context for an ongoing focus on science education across Western nations. Sputnik-era US and UK educational policy offered a broad premise for the purpose of school science: in a risky geopolitical environment, high levels of advanced scientific expertise were central to the national interest and necessary for the maintenance of military/industrial and technological power. Half a century on, in the context of global economic and environmental crisis, as a justification for digital, industrial and biomedical innovation, the rationale for the production of scientific capital is central to curriculum settlements and educational policy in Europe, Asia and the Americas.

Access to potable water is frequently said to be the defining world crisis of the twenty-first century. The argument is usually framed in terms of either direct environmental constraints or various totalistic views of how the political determines outcomes. There is little or no scope for the agency of practical politics. Both physical and human geographers tend to be dismissive of the possibilities of democratic politics ever resolving crises such as those of the geography of water provision, in part because of views of scientific expertise that devalue popular participation in decisions about technical matters such as water quality and distribution. Such dismissal also has much to do with a more generalized denigration of politics. Politics (the art of political deliberation, negotiation, and compromise) needs defending against its critics and many of its practitioners. Showing how politics is at work around the world in managing water problems and identifying the challenges that water problems pose for politics provides a retort to those who can only envisage inevitable destruction or a totalistic political panacea as the outcomes of the crisis of the century.

Les évolutions scientifiques et technologiques engendrent des risques environnementaux complexes. Ces risques doivent être gérés démocratiquement, dans l’intérêt du dêmos. Dans la démocratie représentative, les autorités publiques recourent souvent à l’expertise scientifique pour éclairer leurs décisions relatives à ces risques. Or, ces experts ne le sont pas dans d’autres aspects tout aussi importants tels que les considérations éthiques et les perceptions des risques par le dêmos. En principe, les autorités publiques intègreraient ces autres aspects dans leurs décisions relatives aux risques environnementaux : sur la base d’une évaluation scientifique d’un risque déterminé, les représentants en assureraient une gestion démocratique. Autrement formulé, les autorités publiques garantiraient un filtre démocratique entre l’évaluation scientifique d’un risque environnemental et la décision publique relative à ce risque. Or, sous l’influence exclusive des experts scientifiques et éloignée du dêmos, elles ne sont pas aptes à garantir ce filtre. Les décisions publiques relatives aux risques environnementaux se calquent principalement sur l’évaluation scientifique de ceux-ci. Afin de pallier ces écueils l’idée de faire participer directement le dêmos à l’élaboration de la décision publique environnementale est née. Cette participation enrichirait et nuancerait l’expertise scientifique et permettrait aux autorités publiques d’intégrer dans leurs décisions d’autres facettes des risques environnementaux que les facettes purement scientifiques. Le filtre démocratique entre l’évaluation scientifique et la décision publique serait rétabli. D’abord organisée, en droit international, dans le cadre de l’évaluation des incidences sur l’environnement d’activités susceptibles d’y avoir un impact significatif, la participation directe du public au processus décisionnel a ensuite été étendue. Cela a été tout particulièrement illustré par la convention d’Århus du 25 juin. L’intervention examinera si et comment le système participatif de la convention d’Århus assure réellement une gestion démocratique du risque environnemental et pointera de sérieuses faiblesses démocratiques du système. Explorant les potentialités du système participatif de la convention d’Århus, l’intervention offrira des suggestions pour remédier à ses faiblesses, afin d’assurer une gestion véritablement démocratique du risque environnemental.

Geographic distributions of pathogens are the outcome of dynamic processes involving host availability, susceptibility and abundance, suitability of climate conditions, and historical contingency including evolutionary change. Distributions have changed fast and are changing fast in response to many factors, including climatic change. The response time of arable agriculture is intrinsically fast, but perennial crops and especially forests are unlikely to adapt easily. Predictions of many of the variables needed to predict changes in pathogen range are still rather uncertain, and their effects will be profoundly modified by changes elsewhere in the agricultural system, including both economic changes affecting growing systems and hosts and evolutionary changes in pathogens and hosts. Tools to predict changes based on environmental correlations depend on good primary data, which is often absent, and need to be checked against the historical record, which remains very poor for almost all pathogens. We argue that at present the uncertainty in predictions of change is so great that the important adaptive response is to monitor changes and to retain the capacity to innovate, both by access to economic capital with reasonably long-term rates of return and by retaining wide scientific expertise, including currently less fashionable specialisms.

Despite recent political attempts to re-write the terra nullius myth for Australia, additional Indigenous sub-myth layers about landscape stewardship and cultural knowledge have been substantially overlooked. Pre-contact Indigenous scientific knowledge, landscape architecture strategies, and land stewardship histories and practices have received little legitimate credibility or academic discourse in this rewriting. One sub-myth is that Indigenous Australians have no astronomical scientific expertise and knowledge and that there is no physical evidence of this expertise. Thus, Indigenous Australians possess no ability to translate Dreaming story to astrological configuration, nor explore astronomy. Such is increasingly becoming a myth as it belies a suite of landscape architectural installations and cosmological narratives now being documented and researched. This paper addresses this myth by bringing forth a review of Indigenous cosmological knowledge for south-eastern Australia, with a substantive discussion about archaeo-astronomical evidence. The paper explains the cultural importance of the Wurdi Youang landscape installation for the Wathaurong community, and its role in Australian landscape architectural histories and practice.

Scientific expertise and outcomes often give rise to controversy. An educational response that equips students to take part in such discussions is the teaching of socially acute questions (SAQs). With SAQs, the understanding of uncertainty, risk and how knowledge is developed is central. This study explores the way in which students from different disciplines and different continents are brought together via a digital platform to explore SAQs about environmental issues (a green algae outbreak linked to release of fertilisers along the coast of Brittany; the construction of a desalination plant near Melbourne to produce freshwater; and changes in meat consumption on a global scale, with regard to population projections in 2050). We have developed frameworks for looking at the quality of the collective reasoning and at the nature of students’ interactions, so that we can analyse the organisation of the learning communities and the building of collegial expertise. The results show that interdisciplinary discussions, especially on an international scale, foster the understanding of complex situations. In this paper, we discuss the modalities of one didactic scenario to enhance critical thinking and collaborative work, and to provide space for learners to support argumentation.

A major mission for organizing the series of International Conferences on Environmental Mutagens in Human Populations is to bring science and scientists to the sites where the field of environmental health is in developmental stages and environmental health is a serious concern. The mission has been fulfilled in each of the previous conferences that were held in Egypt, Czech Republic, Thailand and Brazil. These conferences have led to significant enhancement of regional scientific expertise from the acquisition of scientific knowledge and from the generation of sustainable collaborative programs.

Current toxic tort cases have increased national awareness of health concerns and present an important avenue in which public health scientists can perform a vital function: in litigation, and in public health initiatives and promotions which may result. This review presents a systematic approach, using the paradigm of interactive public health disciplines, for the design of a matrix framework for medical surveillance of workers exposed to toxic substances. The matrix framework design addresses the required scientific bases to support the legal remedy of medical monitoring for workers injured as a result of their exposure to toxic agents. A background of recent legal developments which have a direct impact on the use of scientific expertise in litigation is examined in the context of toxic exposure litigation and the attainment of public health goals. The matrix model is applied to five different workplace exposures: dental mercury, firefighting, vinyl chloride manufacture, radon in mining and silica. An exposure matrix designed by the Department of Energy for government nuclear workers is included as a reference comparison to the design matrix. ^
