Understanding the use of science in decision-making on cockle fisheries and gas mining in the Dutch Wadden Sea: Putting the science–policy interface in a wider perspective

The use of science to inform and underpin decision-making on natural resources is not self-evident as stakeholders often use science in a selective and strategic way. Scientific analyses of science utilisation often focus on how the science–policy interface is organised and from this perspective provide recommendations to scientists about how they can increase their contribution to decision-making. Yet in this paper we argue that a wider perspective on the science–policy interface, in particular by analysing the roles and interactions of actors other than those directly involved, provides both additional explanations and new points of application for strategies aimed at enhancing science utilisation. We illustrate our claim by means of an analysis of decision-making on cockle fisheries and gas mining in the Dutch Wadden Sea between the 1990s and 2004. For many years, scientific studies addressing the ecological effects of these activities were not used to meaningfully contribute to decision-making. In 2004 this situation changed radically. Explanations include the role of intermediaries between scientists, stakeholders and decision-makers and new legislation. Scientists could enhance the chances of knowledge utilisation both by creating a more open science–policy interface and by reframing the policy problems at issue.     

The influence of science on Canada's foreign policy on persistent organic pollutants (1985–2001)

The role of science in environmental foreign policymaking has received little attention in the international environmental politics literature, and systematic, in-depth case studies of the influence of science on environmental foreign policy with respect to persistent organic pollutants (POPs) are entirely missing. We present a case study of the influence of science on Canada's foreign policy on POPs from the discovery of the transboundary nature of the POPs problem around 1985 to the signing of the United Nations Stockholm Convention on Persistent Organic Pollutants in 2001. Influence was analyzed in terms of a knowledge–action methodology that focused on the types of scientific knowledge and the actions taken by scientists that were influential. Data were collected through interviews and extensive document analysis. We conclude that, while individual knowledge types and actions were influential during various periods (single-factor explanations), it was an increasingly layered and integrated “package” of knowledge types and actions, with human health impacts as its touchstone and partnering between scientists and non-scientists as its watchword, that propelled and sustained Canada's foreign policy on the POPs issue.

New science for global sustainability? The institutionalisation of knowledge co-production in Future Earth

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.     

Artisanal gold and transformational exchange: toward a public–private partnership in Tanzania

Human rights abuses, environmental predations and governance failures plague artisanal gold mining in Tanzania. Gold's exchange value and the illegality of most artisanal gold product challenge the traditional fair trade model, a potential solution. Additionally, memories of the government's earlier failed effort to serve as a sole purchaser of artisanal gold undercut enthusiasm for statist interventions. This paper presents an alternative: a public–private partnership (PPP) that would engage one or more private banks, an agency within the Ministry of Energy and Minerals and NGOs or international initiatives specifically aimed at improving conditions for artisanal mine operators. The concept of transformational exchange, wherein a set of business transactions substantially affects societal expectations, modifies behavior and promotes sustainable mechanisms, frames the proposal.     

The role of the Subsidiary Body on Scientific,Technical and Technological Advice to the Convention on Biological Diversity as science–policy interface

The Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA) to the Convention on Biological Diversity (CBD) has become the centre of heated debates concerning its function as the science–policy interface of the Convention. Based on explorations of the role, nature, and organisation of scientific advice mechanisms for multilateral environmental agreements in general, we give reasons for SBSTTA's inherently political role in the current governance process of the CBD, and then explore ways to enhance SBSTTA's effectiveness as a science–policy interface, going beyond the usual view that it should merely be “more scientific”. As the quality of SBSTTA's work depends primarily on the processes that guide the discussions during its meetings and on the material on which these discussions are based, we suggest that SBSTTA (a) improves its scientific foundation by systematically strengthening its relations to more scientific institutions outside the formal CBD regime, and (b) focuses on providing for a more substantive political debate to resolve alternative policy choices during its meetings. For this approach to succeed there is a need for a mechanism that provides SBSTTA with timely, salient, legitimate, and credible advice—a role that an International Mechanism of Scientific Expertise on Biodiversity (IMoSEB) could well provide.     

Shifting regime shifted policy—interplay of interests in sustainability discourses of forest land use

This study investigates the influence of policy interests on resource sustainability. Information on ‘colonial interest’ of the British regime and the ‘commercial interest’ of the post-colonial regimes on forest land use of Bangladesh have been drawn on to show the interplay of interests on sustainability impacts. The findings show that both colonial and commercial interests have caused intensification of forest land use for production of economic crops like teak (Tectona grandis) and cash crops like tea (Camellia sinensis), cotton (Gossypium herbaceum and G. arboreum) and tobacco (Nicotiana tabacum). The ‘colonial interest’ has also initiated the dispute of ownership, rights and tenure of forest land and resources. The post-colonial regimes have utilized colonial legacy as the privilege for implementing ‘commercial interests’. In both the cases traditional interests of people were disregarded. As a result, peoples’ participation in forestry was discouraged and the sustainability of forest land use was impeded.

Value positions based on forest policy stakeholders’ rhetoric in Finland

We have investigated value arguments concerning forest policy in Finland and reflected on their prevalence in an international context. The arguments of the organised stakeholders of current forest policy are analysed using semi-structured interview data and secondary material. We have categorised these arguments, and based on them, constructed value positions. The explorative rhetoric analysis reveals shared as well as conflicting values and beliefs.We have identified two dominating value positions: forestry position and nature position. The recognised core values include utility, property rights and value of nature, the utility dominating the policy discussion scene. A principal feature of the polarised policy field is a lack of trust. In addition to the polarisation, there is also a broad common ground in positions towards traditional rights of ownership and access to forests as well as on citizens’ rights to influence forest policy. In order to gain more influence in forest policy, both positions make an effort to redefine the concepts in the argumentation of the others.     

Science–policy interface for addressing environmental problems in arid Spain

Science–policy interfaces are avenues for finding solutions for environmental challenges through strengthening collaborations between research disciplines and public administrations. Here we present a methodology for the conduct of science–policy interfaces between scientists and policymakers for addressing day-to-day environmental problems in the southeastern Spanish drylands. A knowledge brokering approach based on six consecutive workshops was used to facilitate mutual understanding and trust between scientists and policymakers. Water policy and biodiversity loss were identified as major environmental concerns in the region, and 12 final environmental problems were agreed as priorities. A graphical tool was used for diagnosing each environmental problem according to the available scientific knowledge, the current regulatory capacity of administrations, and the level of public engagement necessary for addressing the problem. The use of the graphical tool also allowed for (a) the clarification of roles involved in problem solving, and (b) the promotion of a culture of shared responsibility for the implementation of management actions based on collaborative work. We discuss lessons learned and propose recommendations for future experiences.     

Soil resource supply influences faunal size–specific distributions in natural food webs

The large range of body-mass values of soil organisms provides a tool to assess the ecological organization of soil communities. The goal of this paper is to identify graphical and quantitative indicators of soil community composition and ecosystem functioning, and to illustrate their application to real soil food webs. The relationships between log-transformed mass and abundance of soil organisms in 20 Dutch meadows and heathlands were investigated. Using principles of allometry, maximal use can be made of ecological theory to build and explain food webs. The aggregate contribution of small invertebrates such as nematodes to the entire community is high under low soil phosphorus content and causes shifts in the mass–abundance relationships and in the trophic structures. We show for the first time that the average of the trophic link lengths is a reliable predictor for assessing soil fertility responses. Ordered trophic link pairs suggest a self-organizing structure of food webs according to resource availability and can predict environmental shifts in ecologically meaningful ways.

Sustainable development and the water–energy–food nexus: A perspective on livelihoods

The water–energy–food nexus is being promoted as a conceptual tool for achieving sustainable development. Frameworks for implementing nexus thinking, however, have failed to explicitly or adequately incorporate sustainable livelihoods perspectives. This is counterintuitive given that livelihoods are key to achieving sustainable development. In this paper we present a critical review of nexus approaches and identify potential linkages with sustainable livelihoods theory and practice, to deepen our understanding of the interrelated dynamics between human populations and the natural environment. Building upon this review, we explore the concept of ‘environmental livelihood security’ – which encompasses a balance between natural resource supply and human demand on the environment to promote sustainability – and develop an integrated nexus-livelihoods framework for examining the environmental livelihood security of a system. The outcome is an integrated framework with the capacity to measure and monitor environmental livelihood security of whole systems by accounting for the water, energy and food requisites for livelihoods at multiple spatial scales and institutional levels. We anticipate this holistic approach will not only provide a significant contribution to achieving national and regional sustainable development targets, but will also be effective for promoting equity amongst individuals and communities in local and global development agendas.     

Effects of sulfate-reducing bacteria on methylmercury at the sediment–water interface

Sediment cores(containing sediment and overlying water) from Baihua Reservoir(SW China)were cultured under different redox conditions with different microbial activities, to understand the effects of sulfate-reducing bacteria(SRB) on mercury(Hg) methylation at sediment–water interfaces. Concentrations of dissolved methyl mercury(DMe Hg) in the overlying water of the control cores with bioactivity maintained(BAC) and cores with only sulfate-reducing bacteria inhibited(SRBI) and bacteria fully inhibited(BACI) were measured at the anaerobic stage followed by the aerobic stage. For the BAC and SRBI cores, DMe Hg concentrations in waters were much higher at the anaerobic stage than those at the aerobic stage, and they were negatively correlated to the dissolved oxygen concentrations(r =- 0.5311 and r =- 0.4977 for BAC and SRBI, respectively). The water DMe Hg concentrations of the SRBI cores were 50% lower than those of the BAC cores, indicating that the SRB is of great importance in Hg methylation in sediment–water systems, but there should be other microbes such as iron-reducing bacteria and those containing specific gene cluster(hgc AB), besides SRB,causing Hg methylation in the sediment–water system.     

The chemical stability of heavy metals in a natural water system

A comprehensive investigation of heavy metal pollutants in Xiangjiang river was accomplished to evaluate their chemical stability through three different ways: (1) Chemical speciation by direct measurements; (2) Chemical equilibrium model simulation; (3) Sediment extraction experiments. All the results demonstrated that the directly bioavailable fraction was in a very limited amount. The metal bound to organic ligands, adsorbed particles and precipitated species presented a buffer for solution species. The majority of metals occured in the residues as solid particulates. It was inferred that the heavy metal pollutants in this aquatic system exhibited a high chemical stability. The critical limits of discharging load and pH values were suggested.     

Research on organic matters in the drinking water of Kaschin-Beck disease area

Organic matters in drinking water of Kaschin-Beck disease areas were extracted. Then analyses and characterization were performed by means of multiply chemical and physical methods. The results did not show the obvious difference in the frame structure of humic substances and the structure of rmcromolecular compounds in the drinking water of disease and non-disease areas, but the difference in the contents of some micromolecular compounds and radicals. The investigation also includes the preliminary research on the photoreaction of drinking water from disease and non-disease areas and the accumulation of natural organic matter in the bone of tested animals.     

Knowledge users’ perspectives and advice on how to improve knowledge exchange and mobilization in the case of a co-managed fishery

Environmental scientists have long been frustrated by the difficulties involved in transferring their research findings into policy-making, management, and public spheres. Despite increases in scientific knowledge about social-ecological systems, research has consistently shown that regulators and stakeholders draw on tacit, informal, and experiential knowledge far more than scientific knowledge in their decision-making. Social science research in the fields of knowledge exchange (KE) and knowledge mobilization (KMb) suggest that one of the major barriers to moving knowledge into practice is that scientists fail to align their communication strategies with the information-seeking behaviours and preferences of potential knowledge users. This article presents findings from in-depth qualitative research with government employees and stakeholders involved in co-managing Pacific salmon fisheries in Canada’s Fraser River. We investigate how members of these groups access, view, and use scientific information, finding both similarities and differences. Members of both groups express a strong interest in academic science, and self-report using scientific information regularly in their work and advocacy. However, the two groups engage in different information-seeking behaviours, and provide notably different advice to academic scientists about how to make research and communication more relevant to potential users. For example, government employees focus on the immediate applications of research to known problems, while stakeholders express greater concern for the political context and implications of scientific findings. We argue that scientists need to “go where the users are” in the behavioural and intellectual sense, and tailor their communications and engagement activities to match the habits, preferences, and expectations of multiple potential user groups. We conclude with recommendations on how this may be done.
