RESUMO

Realizing positive social and environmental outcomes from assisted ecosystem adaptation requires the management of complex, uncertain, and ambiguous risks. Using assisted coral reef adaptation as a case study, this article presents a conceptual framework that defines social impacts as the physical and cognitive consequences for people of planned intervention and social risks as potential impacts transformed into objects of management through assessment and governance. Reflecting on its multiple uses in the literature, we consider "social risk" in relation to risks to individuals and communities, risks to First Peoples, risks to businesses or project implementation, possibilities for amplified social vulnerability, and risk perceptions. Although much of this article is devoted to bringing clarity to the different ways in which social risk manifests and to the multiple characters of risk and uncertainty, it is apparent that risk governance itself must be an inherently integrative and social process.

RESUMO

The United States Environmental Protection Agency (EPA) Science Advisory Board (SAB) provides expert advice to inform agency decision-making. Recent regulations have decreased the representation of academic scientists on the EPA SAB and increased the representation of industry scientists. In an experiment, we asked how the US public views the goals and legitimacy of the board as a function of its composition. Respondents perceived SABs with a majority of industry scientists to be more likely to promote business interests than SABs with a majority of academic scientists. Liberals were less likely than conservatives to perceive industry-majority SABs as promoting human health and the environment, and making unbiased and evidence-based decisions. Our findings underscore the potential for politicization of scientific advice to the government.

RESUMO

Risk analysis of new and emerging technologies requires innovative approaches that are agile, exploratory, and can accommodate broad stakeholder engagement and perspectives. Existing theories of risk governance and responsible innovation suggest that operationalizing guiding principles for engagement such as inclusion and reflection may provide a useful approach to the risk analysis of these technologies. Yet, methodologies to systematically assess how we might operationalize such guiding principles in risk analysis are limited in existing risk research. We contribute to filling this gap by demonstrating a practical methodology for examining and documenting how research and development (R&D) professionals operationalize inclusion and reflection in risk analysis and what value this provides to risk analysis in the R&D context. We use the Australian nanotechnology R&D sector as our case study, interviewing 28 experts to examine how R&D professionals have operationalized inclusion and reflection into their risk analysis practices, generating three findings. First, we describe how our research design enables the successful translation of theory into a methodology that supports an empirical assessment of the integration of these guiding principles into risk analysis practice. Second, we argue that successfully and systematically integrating inclusion and reflection in risk analysis fosters a wider understanding and identification of risk through the activation of multi-actor and multi-institutional stakeholder engagement processes. Third, we outline how this research depicts the outward-facing and introspective nature of risk analysis.

RESUMO

Comprehensively addressing different aspects of justice is essential to enable risk management to contribute to sustainable development. This article offers a new conceptual framework called risk justice that comprises procedural, distributive, and corrective justice in four dimensions related to sustainable development: social, ecological, spatial, and temporal issues. Risk justice is defined as the quality of being fair and reasonable while governing and managing a possible negative event. After explaining the conceptual framework, a detailed content analysis of two international guidelines for disaster risk management (the Sendai Framework for Disaster Risk Reduction 2015-2030 and the European Floods Directive) illustrates the analytical potential of the risk justice framework. Findings show strong emphasis on social and spatial aspects of distributive and procedural justice in the two documents, whereas considerations of corrective justice and temporal and ecological issues are scarce or indirect. This may result in conflicting impacts of disaster risk management on sustainable development. Therefore, discussing risk management with a risk justice viewpoint while elaborating guidelines or choosing risk management strategies provides new avenues for sustainable development and facilitates transparent trade-offs. Our risk justice framework enables risk practitioners and researchers to reflect systemically about justice in risk management in different risk contexts and can be used both as a proactive and as a retrospective tool.

RESUMO

Systemic risks are characterized by high complexity, multiple uncertainties, major ambiguities, and transgressive effects on other systems outside of the system of origin. Due to these characteristics, systemic risks are overextending established risk management and create new, unsolved challenges for policymaking in risk assessment and risk governance. Their negative effects are often pervasive, impacting fields beyond the obvious primary areas of harm. This article addresses these challenges of systemic risks from different disciplinary and sectorial perspectives. It highlights the special contributions of these perspectives and approaches and provides a synthesis for an interdisciplinary understanding of systemic risks and effective governance. The main argument is that understanding systemic risks and providing good governance advice relies on an approach that integrates novel modeling tools from complexity sciences with empirical data from observations, experiments, or simulations and evidence-based insights about social and cultural response patterns revealed by quantitative (e.g., surveys) or qualitative (e.g., participatory appraisals) investigations. Systemic risks cannot be easily characterized by single numerical estimations but can be assessed by using multiple indicators and including several dynamic gradients that can be aggregated into diverse but coherent scenarios. Lastly, governance of systemic risks requires interdisciplinary and cross-sectoral cooperation, a close monitoring system, and the engagement of scientists, regulators, and stakeholders to be effective as well as socially acceptable.

RESUMO

The article distinguishes between two types of risks: conventional and systemic risks. Conventional risks can be contained in space and time, follow linear cause-effect relationships and can be addressed with effective and pointed interventions into the cause-effect chain. Systemic risks, however, are characterized by high complexity, transboundary effects, stochastic relationships, nonlinear cause-effect patterns with tipping points, and are often associated with less public attention than they require. The article addresses the reasons why systemic risks seem to be attenuated in public perception. The article goes on to consider how the social amplification of risk framework is useful in the context of systemic risks and describes needed extensions of that framework. It identifies practical tools for assessing the significance of perceptions for systemic risk situations. Finally, it argues that a graphic representation and simulation of evolving systemic risks and potential countermeasures as well as a participatory deliberative approach of inclusive risk governance are suitable governance strategies for preventing, mitigating, or managing systemic risks.

RESUMO

The social amplification of risk framework (SARF) was developed to help comprehend how emerging contributions about the psychological, social, and cultural dimensions of risk could work in unison to impact decision making about risk. The framework proposed that risks are amplified or attenuated by interested parties employing different rhetorical strategies to give information about risk a certain "spin." The original literature identified four "attributes of information." However, despite the longevity of the framework, these have not been explicated in detail. Here we add depth and clarity by examining how amplification stations send risk signals that amplify or attenuate risk by emphasizing these different attributes of information. Drawing on a wealth of qualitative data from two case studies of offshore wind turbine siting off the coasts of Maryland and Delaware and guided by an extensive literature review, we reveal the strategies interested parties are using to influence siting decisions and risk management. The paper explores the usefulness of SARF in organizing qualitative information and sharpening insights on participatory risk governance and the nuances of public responses to a relatively new low-carbon technology. The authors conclude that the framework is valuable for analyzing stakeholder information while also recognizing limitations that may be addressed with some targeted future research.

RESUMO

BACKGROUND: The African Union's High-Level Panel on Emerging Technologies identified gene drive mosquitoes as a priority technology for malaria elimination. The first field trials are expected in 5-10 years in Uganda, Mali or Burkina Faso. In preparation, regional and international actors are developing risk governance guidelines which will delineate the framework for identifying and evaluating risks. Scientists and bioethicists have called for African stakeholder involvement in these developments, arguing the knowledge and perspectives of those people living in malaria-afflicted countries is currently missing. However, few African stakeholders have been involved to date, leaving a knowledge gap about the local social-cultural as well as ecological context in which gene drive mosquitoes will be tested and deployed. This study investigates and analyses Ugandan stakeholders' hopes and concerns about gene drive mosquitoes for malaria control and explores the new directions needed for risk governance. METHODS: This qualitative study draws on 19 in-depth semi-structured interviews with Ugandan stakeholders in 2019. It explores their hopes for the technology and the risks they believed pertinent. Coding began at a workshop and continued through thematic analysis. RESULTS: Participants' hopes and concerns for gene drive mosquitoes to address malaria fell into three themes: (1) ability of gene drive mosquitoes to prevent malaria infection; (2) impacts of gene drive testing and deployment; and, (3) governance. Stakeholder hopes fell almost exclusively into the first theme while concerns were spread across all three. The study demonstrates that local stakeholders are able and willing to contribute relevant and important knowledge to the development of risk frameworks. CONCLUSIONS: International processes can provide high-level guidelines, but risk decision-making must be grounded in the local context if it is to be robust, meaningful and legitimate. Decisions about whether or not to release gene drive mosquitoes as part of a malaria control programme will need to consider the assessment of both the risks and the benefits of gene drive mosquitoes within a particular social, political, ecological, and technological context. Just as with risks, benefits-and importantly, the conditions that are necessary to realize them-must be identified and debated in Uganda and its neighbouring countries.

RESUMO

Proposed as an advanced conceptualization of how to handle risk, risk governance begins with the critique and expansion of the traditional idea and standard practices of risk analysis. In developments over the last two decades, proponents of a more integrative approach on governing risks have moved further away from distinct conceptions of risk assessment, risk management, and risk communication and toward the processes and institutions that guide, restrain, and integrate collective activities of handling risk. In early formulations of what risk governance entails, the superiority of the interplay between risk evaluation and risk management over linear and simple deductions from risk assessment to risk management was established precisely by developing a distinctive rationality of how to proceed. Later, the International Risk Governance Council recaptured this distinctive rationality that institutionalized processes should embody the interplay of the assessment of risks and related concerns, their sociopolitical appraisal, and the logical inference for risk management. Recently, this approach has been refined and augmented toward an integrative and adaptive concept of risk governance and toward a postnormal conception of risk governance. Main characteristics are a new concept of differentiated responsibility and deliberation in which expertise, experience, and tacit knowledge are integrated, forming the core of legitimate political risk decision making.

RESUMO

This paper reflects on what materialised during recovery operations following the earthquake in L'Aquila, Italy, on 6 April 2009. Previous critiques have focused on the actions of the Government of Italy and the Department of Civil Protection (Protezione Civile), with little attention paid to the role of local authorities. This analysis sheds light on how the latter used emergency powers, the command-and-control approach, and top-down planning to manage the disaster context, especially in terms of removal of rubble, implementing safety measures, and allocating temporary accommodation. It discusses how these arrangements constituted the mechanism via which 'disaster capitalism' took hold at the local and national level, and how it violated human rights, produced environmental and social impacts, hindered local communities from learning, transforming, and building resilience, and facilitated disaster capitalism and corruption. To make the disaster risk reduction and resilience paradigm more effective, a shift from centralised civil protection to decentralised, inclusive community empowerment systems is needed.

RESUMO

Nanotechnologies have reached maturity and market penetration that require nano-specific changes in legislation and harmonization among legislation domains, such as the amendments to REACH for nanomaterials (NMs) which came into force in 2020. Thus, an assessment of the components and regulatory boundaries of NMs risk governance is timely, alongside related methods and tools, as part of the global efforts to optimise nanosafety and integrate it into product design processes, via Safe(r)-by-Design (SbD) concepts. This paper provides an overview of the state-of-the-art regarding risk governance of NMs and lays out the theoretical basis for the development and implementation of an effective, trustworthy and transparent risk governance framework for NMs. The proposed framework enables continuous integration of the evolving state of the science, leverages best practice from contiguous disciplines and facilitates responsive re-thinking of nanosafety governance to meet future needs. To achieve and operationalise such framework, a science-based Risk Governance Council (RGC) for NMs is being developed. The framework will provide a toolkit for independent NMs' risk governance and integrates needs and views of stakeholders. An extension of this framework to relevant advanced materials and emerging technologies is also envisaged, in view of future foundations of risk research in Europe and globally.

RESUMO

Advanced gene editing techniques such as Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)/Cas have increased the pace of developments in the field of industrial biotechnology. Such techniques imply new possibilities when working with living organisms, possibly leading to uncertain risks. In the Netherlands, current policy fails to address these uncertain risks because risk classification is determined process-wise (i.e., genetically modified organism [GMO] and non-GMO), there is a strong focus on quantifiable risks, and the linearity within current governance (science-policy-society) hinders iterative communication between stakeholders, leaving limited room to anticipate uncertainties at an early stage of development. A suggested concept to overcome these shortcomings is the Safe-by-Design (SbD) approach, which, theoretically, allows stakeholders to iteratively incorporate safety measures throughout a technology's development process, creating a dynamic environment for the anticipation of uncertain risks. Although this concept originates from chemical engineering and is already widely applied in nanotechnology, for the field of biotechnology, there is no agreed upon definition yet. To explore the possibilities of SbD for future governance of biotechnology, we should gain insight in how various stakeholders perceive notions of risk, safety, and inherent safety, and what this implies for the applicability of SbD for risk governance concerning industrial biotechnology. Our empirical research reveals three main themes: (1) diverging expectations with regard to safety and risks, and to establish an acceptable level of risk; (2) different applications of SbD and inherent safety, namely, product- and process-wise; and (3) unclarity in allocating responsibilities to stakeholders in the development process of a biotechnology and within society.

RESUMO

Mining tailing dam ruptures are increasingly common events in South America. Due to their high potential degree for avoidance, they are considered to be technological disasters and often have a considerable impact on local populations and communities, as well as affecting the ecosystem. The failure of the Fundão dam in 2015 in the Brazilian State of Minas Gerais (is) considered one of the largest socioenvironmental disasters in the country's history. Different explanations for the causes of the disaster were put forward by various social actors. This article critically analyzes these discourses through the theoretical-methodological reference of the social theory of discourse, with the aim of understanding the various discursive contexts of the causes of the breach of the dam. The analysis and understanding of these explanatory matrices suggested that different discourses present different epistemological approaches to the causes of the disaster, related to aspects such as sociohistorical, political, ideological, and asymmetric relations of power. The statements had different emphases, being associated with distinct epistemic positions that were often not in convergence.  Moreover, certain terms and approaches reinforce or minimize processes of vulnerability experienced by the affected populations. These discourses present consents, dissents, and contradictions and when systematically integrated can improve the planning of risk management and broaden the understanding related to technological disaster occurrence.

RESUMO

BACKGROUND: Engagement of patients and healthcare professionals is increasingly considered as fundamental to pharmacovigilance and risk minimisation activities. Few empirical studies of engagement exist and a lack of explicit conceptualisations impedes effective measurement, research and the development of evidence-based engagement interventions. AIMS: This article (1) develops a widely applicable conceptualisation, (2) considers various methodological challenges to researching engagement, proposing some solutions, and (3) outlines a basis for converting the conceptualisation into specific measures and indicators of engagement among stakeholders. METHOD: We synthesise social science work on risk governance and public understandings of science with insights from studies in the pharmacovigilance field. FINDINGS: This leads us to define engagement as an ongoing process of knowledge exchange among stakeholders, with the adoption of this knowledge as the outcome which may feed back into engagement processes over time. We conceptualise this process via three dimensions; breadth, depth and texture. In addressing challenges to capturing each dimension, we emphasise the importance of combining survey approaches with qualitative studies and secondary data on medicines use, prescribing, adverse reaction reporting and health outcomes. A framework for evaluating engagement intervention processes and outcomes is proposed. Alongside measuring engagement via breadth and depth, we highlight the need to research the engagement process through attentiveness to texture-what engagement feels like, what it means to people, and how this shapes motivations based on values, emotions, trust and rationales. CONCLUSION: Capturing all three dimensions of engagement is vital to develop valid understandings of what works and why, thus informing engagement interventions of patients and healthcare professionals to given regulatory pharmacovigilance scenarios.

RESUMO

BACKGROUND: Complementary and alternative medicine (CAM) is a rather novel issue within public healthcare and health policy-making. CAM use in Europe is widespread, patient-initiated, and patient-evaluated, and the regulation across countries has been evaluated as disharmonized. CAM users are left in an uncertain position, and patient safety may be threatened. How "risk" is understood by individuals in health policy-making and clinical encounters involving the use of CAM has not yet been much debated. The aim of this article is to explore and discuss the existence and possible consequences of differing risk understandings among stakeholders maneuvering in the complex landscape of CAM practice and CAM regulation contextualized by European public healthcare systems. METHODS: Qualitative data were derived from two studies on CAM in European healthcare contexts. Findings from the EU project CAMbrella on legislation and regulation of CAM were mixed with data from an interview study exploring risk understandings, communication, and decision-making among Scandinavian CAM users and their doctors. In a secondary content analysis, we constructed the case Sara as a typology to demonstrate important findings with regard to risk understandings and patient safety involving European citizens' use of CAM in differing contexts. RESULTS: By combining and comparing individual and structural perspectives on risk and CAM use, we revealed underexplored gaps in risk understandings among individuals involved in European CAM regulation and legislation, and between CAM users and their medical doctors. This may cause health risks and uncertainties associated with CAM use and regulation. It may also negatively influence doctor-CAM user communication and CAM users' trust in and use of public healthcare. CONCLUSION: Acknowledging implications of stakeholders' differing risk understandings related to CAM use and regulation may positively influence patient safety in European healthcare. Definitions of the concept of risk should include the factors uncertainty and subjectivity to grasp the full picture of possible risks associated with the use of CAM. To transform the findings of this study into practical settings, we introduce sets of questions relevant to operationalize the important question "What is risk?" in health policy-making, clinical encounters and risk research involving European patients' use of CAM.

RESUMO

The most important theoretical argument concerning decentralised participatory governance is that it can make a government more accountable for the needs of the governed. Key to this process are participatory spaces that act as mechanisms for dialogue between citizens and local government. However, within Cochabamba, a city in the centre of Bolivia, South America, 'at-risk' citizens engage minimally with disaster risk issues in participatory spaces, despite high levels of civic participation. This is because 'at-risk' populations view disasters as a private/household problem that is symptomatic of household error, rather than seeing them as a broader public problem due to wider structural inequalities. Consequently, they redistribute responsibility for disaster risk reduction towards households, which (re)produces the absolution of government authorities as guarantors of disaster risk reduction. This paper challenges the normative assumption that participatory spaces facilitate democratic deliberation of disaster risk reduction and the downward accountability of local government for disaster risk reduction.

RESUMO

Southern European countries rely largely on fire suppression and ignition prevention to manage a growing wildfire problem. We explored a more wholistic, long-term approach based on priority maps for the implementation of diverse management options aimed at creating fire resilient landscapes, restoring cultural fire regimes, facilitating safe and efficient fire response, and creating fire-adapted communities. To illustrate this new comprehensive strategy for fire-prone Mediterranean areas, we developed and implemented the framework in Catalonia (northeastern Spain). We first used advanced simulation modeling methods to assess various wildfire exposure metrics across spatially changing fire-regime conditions, and these outputs were then combined with land use maps and historical fire occurrence data to prioritize different fuel and fire management options at the municipality level. Priority sites for fuel management programs concentrated in the central and northeastern high-hazard forestlands. The suitable areas for reintroducing fires in natural ecosystems located in scattered municipalities with ample lightning ignitions and minimal human presence. Priority areas for ignition prevention programs were mapped to populated coastal municipalities and main transportation corridors. Landscapes where fire suppression is the principal long-term strategy concentrated in agricultural plains with a high density of ignitions. Localized programs to build defensible space and improve self-protection on communities could be emphasized in the coastal wildland-urban interface and inner intermix areas from Barcelona and Gerona. We discuss how the results of this study can facilitate collaborative landscape planning and identify the constraints that prevent a longer term and more effective solution to better coexist with fire in southern European regions.

RESUMO

This article is a retrospective analysis of liquefied natural gas development (LNG) in Gladstone, Australia by using the structure of the risk governance framework developed by the International Risk Governance Council (IRGC). Since 2010 the port of Gladstone has undergone extensive expansion to facilitate the increasing coal export as well as the new development of three recently completed LNG facilities. Significant environmental and socio-economic impacts and concerns have occurred as a result of these developments. The overall aim of the article, therefore, is to identify the risk governance deficits that arose and to formulate processes capable of improving similar decision-making problems in the future. The structure of the IRGC framework is followed because it represents a broad analytical approach for considering risk assessment and risk governance in Gladstone in ways that include, but also go beyond, the risk approach of the ISO 31000:2009 standard that was employed at the time. The IRGC risk framework is argued to be a consistent and comprehensive risk governance framework that integrates scientific, economic, social, and cultural aspects and advocates the notion of inclusive risk governance through stakeholder communication and involvement. Key aspects related to risk preassessment, risk appraisal, risk tolerability and acceptability, risk management, and stakeholder communication and involvement are considered. The results indicate that the risk governance deficits include aspects related to (i) the risk matrix methodology, (ii) reflecting uncertainties, (iii) cumulative risks, (iv) the regulatory process, and (v) stakeholder communication and involvement.

RESUMO

We assessed transboundary wildfire exposure among federal, state, and private lands and 447 communities in the state of Arizona, southwestern United States. The study quantified the relative magnitude of transboundary (incoming, outgoing) versus nontransboundary (i.e., self-burning) wildfire exposure based on land tenure or community of the simulated ignition and the resulting fire perimeter. We developed and described several new metrics to quantify and map transboundary exposure. We found that incoming transboundary fire accounted for 37% of the total area burned on large parcels of federal and state lands, whereas 63% of the area burned was burned by ignitions within the parcel. However, substantial parcel to parcel variation was observed for all land tenures for all metrics. We found that incoming transboundary fire accounted for 66% of the total area burned within communities versus 34% of the area burned by self-burning ignitions. Of the total area burned within communities, private lands contributed the largest proportion (36.7%), followed by national forests (19.5%), and state lands (15.4%). On average seven land tenures contributed wildfire to individual communities. Annual wildfire exposure to structures was highest for wildfires ignited on state and national forest land, followed by tribal, private, and BLM. We mapped community firesheds, that is, the area where ignitions can spawn fires that can burn into communities, and estimated that they covered 7.7 million ha, or 26% of the state of Arizona. Our methods address gaps in existing wildfire risk assessments, and their implementation can help reduce fragmentation in governance systems and inefficiencies in risk planning.

RESUMO

Societies worldwide are investing considerable resources into the safe development and use of nanomaterials. Although each of these protective efforts is crucial for governing the risks of nanomaterials, they are insufficient in isolation. What is missing is a more integrative governance approach that goes beyond legislation. Development of this approach must be evidence based and involve key stakeholders to ensure acceptance by end users. The challenge is to develop a framework that coordinates the variety of actors involved in nanotechnology and civil society to facilitate consideration of the complex issues that occur in this rapidly evolving research and development area. Here, we propose three sets of essential elements required to generate an effective risk governance framework for nanomaterials. (1) Advanced tools to facilitate risk-based decision making, including an assessment of the needs of users regarding risk assessment, mitigation, and transfer. (2) An integrated model of predicted human behavior and decision making concerning nanomaterial risks. (3) Legal and other (nano-specific and general) regulatory requirements to ensure compliance and to stimulate proactive approaches to safety. The implementation of such an approach should facilitate and motivate good practice for the various stakeholders to allow the safe and sustainable future development of nanotechnology.
