Discourse about the L'Aquila trial in Italy has overlooked the many different roles that laws play within risk governance. For volcanic risk governance, laws not only create the duty holders, beneficiaries and the relationships between them (the stakeholders) and the duties and rights (the stakes) but also dictate the acceptable standards of safety and wellbeing (the ultimate rewards). Within any legal regime, certain court cases will attract a high public profile. They can serve a very helpful role by opening the black box of societal risk management so that robust and candid scrutiny of the past can lead to better management of the future. With such cases, the goal of the competent observer is to advance beyond debate about contested factual details of the past (the noise of what happened) and, by process of induction, to identify wider issues of principle and precedent upon which to make reasoned improvements (the signal to guide what should happen differently in the future and why). The generic characteristics of law-based regulatory regimes are identified because they can be treated as 'constants' which do not change, or do so only very slowly over time. Accordingly, these aspects are highly relevant to long-term risk governance. More ephemeral case-specific factual issues often remain contested and, accordingly, receive less attention here. Significant recent court cases, including L'Aquila, are framed by process of deduction within a generalised legal infrastructure in order to identify the root causes of the apparent status quo of risk governance. This forensic approach is vital not only to identify the legal responsibilities of societal risk managers and the managerial risks that they face and their causes but also to consider possible mitigation strategies. We identify the critical issue of managerial risk vulnerability related to 'standard equivocality' which is the absence of commonly recognised standards for hazard communications to risk decision makers. This absence may result from the lack of regulation of relevant practices and practitioners. We offer some recommendations to fuel debate not only within those science groups that reacted to the L'Aquila case but also the scientific community as a whole. Finally, we argue that checklists represent a rational and methodical way to develop acceptable practice standards focussed upon the difficult risk mitigation choices that are made by civil protection authorities and at-risk individuals.
Scientific communication is one of the most challenging aspects of volcanic risk management because the complexities and uncertainties of volcanic unrest make it difficult for scientists to provide information that is timely, relevant, easily comprehensible and trusted. When poorly handled, scientific communication can cause social, economic and political problems, and undermine community confidence in disaster management regimes. This is the first of two related papers that together investigate the interface between the scientific consideration of volcanic hazards and the governance of volcanic risks. Both papers are principally concerned with issues of risk governance, and their focus is hazard communication by volcanologists at this hazard-risk interface (the interface) during periods of volcanic unrest. In this paper, we argue that the working practices of contextualisation must be more methodical and propose four quality assurance standards that will enhance hazard assessments. To improve hazard communication between volcanologists and risk-mitigation decision-makers (decision-makers), we argue that volcanologists need to adopt a more iterative and structured approach that openly embraces the benefits, and confronts the challenges, of stakeholder-orientated 'contextualisation'. Our analysis of the published literature reveals evidence of a slow paradigm shift from practices based upon strict linear technocratic approaches to more iterative stakeholder participation. The extent of this shift varies in different regions, however, the rules and practices of deliberation often appear ad hoc and unstructured. Since there is currently insufficient guidance for managing the practicalities and standards of contextualisation, we introduce two novel concepts; the 'scrutiny dimension' of risk governance, which is the slow changing governance context that may influence the processes of contextualisation, and the dynamic 'equilibrium of contextualisation', which is the metastable product of regulatory standards, natural and organisational constraints, and stakeholder pressures. We argue that the working practices of contextualisation must be more structured and should strive to be open, transparent and fully articulated. Contextualisation, which meets proposed quality assurance standards of materiality, proximity, comprehensibility and integrity, will enhance hazard assessments and, thereby, the utility of their outputs. In our second paper (Bretton et al, J Appl. Volcanol.
and colleagues propose ways to improve cancer care globally (Nature 549, 325-328; 2017). For lower-income countries, we suggest that local measures could contribute if they were promoted and developed globally with the help of highincome countries. 'Frugal innovation' in medicine in low-resource settings can suggest cost-effective strategies that are adapted to local constraints to meet an area's needs (see go.nature.com/2hqsyqz). Clinical trials funded by wealthier nations could test the repurposing of inexpensive drugs, such as statins and aspirin, for cancer care (F. Bertolini et al. Nature Rev. Clin. Oncol. 12, 732-742; 2015). This would help to build medical infrastructure in poorer countries. Clinicians in low-to-middleincome countries have generated data to support drug repurposing, for example using the β-blocker propranolol to treat blood-vessel cancer (angiosarcoma; see E. Pasquier et al. EBioMedicine 6, 87-95; 2016). High-income nations should show much greater interest in such findings, especially in view of the financial burden of cancer treatment. By investing in co-development, they can help to ensure that care is effective, affordable and equitable globally.
Contextualisation is the critical process of interactions between volcanologists and risk governance decision-makers and specifically the tailoring of hazard assessments to ensure they are driven by the needs of decision-makers. Quality assurance standards for the contextualisation of the analysis and communication of volcanic hazards do not formally exist. For volcanologists this governance lacuna creates a foreseeable and avoidable managerial hazard. This is the second of two papers that together investigate the interface between the scientific treatment of volcanic hazards and the governance of volcanic risks. Both papers are principally concerned with issues of risk governance and their focus is hazard communication by volcanologists at this hazard-risk interface (the interface) during periods of volcanic unrest. In our first paper "Hazard communication by volcanologists: Part 1 -Framing the case for contextualisation and related quality standards in volcanic hazard assessments", (Bretton et al, J Appl. Volcanol. DOI 10.1186/ s13617-018-0077-x, 2018) we investigated the perceived qualities of more 'socially robust' hazard assessments and argued that the working practices of contextualisation must be more methodical.In this paper, we focus on the actual process of contextualisation and argue that quality assurance standards need to be devised and adopted by volcanologists undertaking hazard assessments that are robust enough to bear legal scrutiny. Such standards are necessary: (1) to facilitate a more structured approach to contextualisation; (2) to preserve the core values of traditional scientific methodologies; (3) to address a working assumption that, in the absence of effective regulation, the 'equilibrium of contextualisation' may be unduly influenced by the demands of decisionmakers; and (4) to mitigate the managerial risks related to volcanologists assuming responsibility for contextualisation. Our initial literature review reveals the realities of contextualisation in the absence of effective regulation and identifies many of the foreseeable practical challenges historically faced by volcanic hazard assessors. We investigate and characterise these challenges in order to develop quality standards tailored for practical use. In addition, we present new empirical data acquired from a survey of 33 experienced volcanologists, 18 of whom were selected for one-to-one semi-structured interviews. The survey captures a snapshot of working practices and related sentiments that might indicate whether a more structured approach to contextualisation would find favour amongst volcanologists and, if so, what principles of contextualisation would be most acceptable. This evaluation of published evidence and new data permits us to identify seven aspects of volcanic hazard assessments relevant to quality assurance -the methods and status of hazard analyses, and the delivery, content, status, perception and advice content of hazard communications. Our proposed quality standards and related proto-type code of practice to...
When a volcano emerges from dormancy into a phase of unrest, the civil protection authorities charged with managing societal risks have the unenviable responsibility of making difficult decisions balancing numerous competing societal, political and economic considerations. A volcano that is threatening to erupt requires sound risk assessments incorporating trusted hazard assessments that are timely, relevant and comprehensible. Foreseeable challenges arise when the inevitable uncertainties of hazard assessment and communication meet societal and political demands for certitude. In some regions that host volcanic hazards, it would be both realistic and prudent to adopt three working assumptions. The complex legal and administrative infrastructures of risk governance will be largely untested and possibly inadequate. Many volcano observatory scientists, and probably even more risk managers and at-risk individuals/communities, will have inadequate recent experience of the challenges of hazard communication during a period of unrest. And lastly, the scientists may also have inadequate practical experience of the needs and management capacities of the risk-mitigation decision makers with whom they must communicate. "Practice doesn't make perfect. Practice reduces the imperfection." (Beta 2011). If this statement is correct, volcanic unrest simulation exercises (VUSE) have a vital role to play within the complex processes of volcanic risk governance. Consistent with the broad approach of the Sendai Framework for Risk Reduction 2015-30, this chapter argues that practical knowledge of VUSE can and should be analysed and recorded so that key lessons can be shared for the widest possible benefit. This chapter investigates five recent simulation exercises and presents six complementary checklists based upon data, insights and practice pointers derived from those exercises. The use of checklists, supported by guidance notes, is commended as a pragmatic way to create, test and develop acceptable standards of governance practice. It is argued here that well planned and executed simulation exercises are capable of informing and motivating a wide range of risk governance stakeholders. They can identify process and individual shortcomings that can be mitigated. Simulation exercises can and should play a vital role in reducing volcanic risks.
