Wildfire evacuation and its alternatives in a post-Black Saturday landscape: Catchy slogans and cautionary tales

Prior to 2009 the United States and Australia were seeing increased interest, implementation and research support for alternatives to evacuation during wildfire – a broad class of strategies that would enable residents to remain in their homes or other designated safe areas during the pass of a flame front. Yet policy discussion of alternatives to evacuation in both countries shifted in the wake of Australias 2009 Black Saturday Fires, which resulted in 173 deaths and burned approximately 430,000 ha. Soon after, the United States and Australia began implementing new approaches to public and property safety during wildfire events. The goal of this manuscript is to discuss key provisions of these emerging approaches to public safety during wildfire and evaluate their possible legacies. We do so by contrasting approaches in both countries with research insights on alternatives to evacuation during wildfire events. Insights are also paired with broader lessons from research on hazard, risk communication and wildfire. Our analysis provides insight on how emerging approaches could impact broader policy objectives for ‘creating fire-adapted communities’ and/or affect resident responsibility for personal wildfire protection. We suggest ways to influence these possible legacies through careful implementation and possible revision of emerging approaches to public safety during wildfire.

Canadian Media Representations of Mad Cow Disease

A Canadian case of bovine spongiform encephalopathy (BSE) or “mad cow disease” was confirmed in May, 2003. An in-depth content analysis of newspaper articles was conducted to understand the portrayal of BSE and variant Creutzfeldt–Jakob disease (vCJD) in the Canadian media. Articles in the “first 10 days” following the initial discovery of a cow with BSE in Canada on May 20, 2003, were examined based on the premise that these initial stories provide the major frames that dominate news media reporting of the same issue over time and multiple occurrences. Subsequent confirmed Canadian cases were similarly analyzed to determine if coverage changed in these later media articles. The results include a prominence of economic articles, de-emphasis of health aspects, and anchoring the Canadian outbreak to that of Britains crisis. The variation in media representations between those in Canada and those documented in Britain are explored in this study.

Front page or “buried” beneath the fold? Media coverage of carbon capture and storage

Media can affect public views and opinions on science, policy and risk issues. This is especially true of a controversial emerging technology that is relatively unknown. The study presented here employs a media content analysis of carbon capture and storage (CCS), one potential strategy to reduce greenhouse gas emissions. The authors analyzed all mentions of CCS in two leading Canadian national newspapers and two major western regional newspapers from the first article that discussed CCS in 2004 to the end of 2009 (825 articles). An in-depth content analysis was conducted to examine factors relating to risk from CCS, how the technology was portrayed and if coverage was negatively or positively biased. We conclude by discussing the possible impact of media coverage on support or opposition to CCS adoption.

Examining Community Perceptions of Energy Systems Development: The Role of Communication and Sense of Place

An increasing demand for the development and implementation of low carbon energy systems has furthered the need to understand the factors that influence a communitys support for or opposition to local energy developments. Carbon dioxide capture and geological storage (CCS) is one such energy system where it is widely acknowledged that public perceptions and acceptance of CCS technologies are critical to their implementation. CCS refers to the capture of carbon dioxide emissions from industrial sources and the long-term storage of these emissions in stable underground reservoirs. This case study examines how place attachment and community networks factored into residents perceptions of a proposed CCS project that was ultimately canceled due to local opposition. Participants were concerned about preserving shared places, spaces, and interactions that were valued by community members. Results demonstrate the need to ascertain how locally affected populations view CCS or other energy developments, especially with regard to their ideas about community, sense of place (ties to area and local relationships), and how they communicate about those factors. Such factors are important given the initiative to develop low carbon energy systems in rural areas.

The More the Better? A Comparison of the Information Sources Used by the Public during Two Infectious Disease Outbreaks

Recent infectious disease outbreaks have resulted in renewed recognition of the importance of risk communication planning and execution to public health control strategies. Key to these efforts is public access to information that is understandable, reliable and meets their needs for informed decision-making on protective health behaviours. Learning from the trends in sources used in previous outbreaks will enable improvements in information access in future outbreaks. Two separate random-digit dialled telephone surveys were conducted in Alberta, Canada, to explore information sources used by the public, together with their perceived usefulness and credibility, during the 2003 Severe Acute Respiratory Syndrome (SARS) epidemic (n = 1209) and 2009–2010 H1N1 pandemic (n = 1206). Traditional mass media were the most used information sources in both surveys. Although use of the Internet increased from 25% during SARS to 56% during H1N1, overall use of social media was not as high as anticipated. Friends and relatives were commonly used as an information source, but were not deemed very useful or credible. Conversely, doctors and health professionals were considered credible, but not consulted as frequently. The use of five or more information sources increased by almost 60% between the SARS and H1N1 surveys. There was a shift to older, more educated and more affluent respondents between the surveys, most likely caused by a decrease in the use of landlines amongst younger Canadians. It was concluded that people are increasingly using multiple sources of health risk information, presumably in a complementary manner. Subsequently, although using online media is important, this should be used to augment rather than replace more traditional information channels. Efforts should be made to improve knowledge transfer to health care professionals and doctors and provide them with opportunities to be more accessible as information sources. Finally, the future use of telephone surveys needs to account for the changing demographics of the respondents accessed through such surveys.

Re-conceptualizing community in risk research

Community is an important concept for determining the factors that influence peoples’ perceptions of and actions surrounding risk. However, there are multiple and conflicting definitions for the concept of community and scholars operationalize it in various ways. In this paper, we argue for a renewed focus on community as a guiding consideration in discussions of risk management and the related concepts of resilience, vulnerability, and adaptive capacity. We outline classic and current conceptions of community to articulate how its conceptualization in ongoing risk research might lead to different outcomes, foci, or recommendations about collective adaptation. This includes a discussion of how historic and emerging methodological approaches for studying risk make implicit choices about what community is or how it influences collective response. We close by providing a set of potential axioms that can help researchers better integrate the complexity of community into studies of risk and understand how populations respond to it. Better integrating community into studies of risk could promote policies and communication that are tailored to the unique local context of diverse populations. Such tailoring is more likely to promote adoption of risk mitigations among local populations and perpetuate adaptation as a part of local culture. We contend that a more holistic and systematic approach to documenting local context better encompasses the variable influences that community can have on collective ability to respond to risks.

Did public risk perspectives of mad cow disease reflect media representations and actual outcomes

The first confirmed Canadian case of bovine spongiform encephalopathy (BSE) was reported to the general public on 20 May 2003 and received considerable media coverage. A random‐digit dialled telephone survey of 1207 people in Alberta, Canada, was conducted in spring 2007 to better understand public perspectives on the resulting economic concerns and effects on farming. Comparisons to other risk events and concerns about the overall risk were also examined. Respondents acknowledged BSE to be an economic risk, especially to cattle producers. Health risks were of little concern, especially in comparison to other relevant risk events such as severe acute respiratory syndrome (SARS) and the BSE crisis in Britain. However, the risk of BSE was perceived as more dangerous should a domestically attributed case of variant Creutzfeldt‐Jakob disease (vCJD) (the human form of the disease) occur. The social amplification of risk framework (SARF) was extended to demonstrate that the discovery of BSE in Alberta led to neither an amplification nor attenuation of risk. Rather, risk management strategies employed in Alberta led to a mirroring of media representations and public perceptions of the risk. This unusual situation is in part due to the social and cultural context of the discovery of BSE in Alberta, including the history and pride of beef production in Alberta, how the risk was anchored, and a trust in government fostered by the media. This research also demonstrated how the application and interpretation of SARF is dependent on the comparative value used to assess whether amplification or attenuation has occurred.

Investigating the effect of forestry on leaf-litter arthropods (Algonquin Park, Ontario, Canada)

Arthropods are the most diverse taxonomic group of terrestrial eukaryotes and are sensitive to physical alterations in their environment such as those caused by forestry. With their enormous diversity and physical omnipresence, arthropods could be powerful indicators of the effects of disturbance following forestry. When arthropods have been used to measure the effects of disturbance, the total diversity of some groups is often found to increase following forestry. However, these findings are frequently derived using a coarse taxonomic grain (family or order) to accommodate for various taxonomic impediments (including cryptic diversity and poorly resourced taxonomists). Our intent with this work was to determine the diversity of arthropods in and around Algonquin Park, and how this diversity was influenced by disturbance (in this case, forestry within the past 25 years). We used DNA barcode-derived diversity estimates (Barcode Index Number (BIN) richness) to avoid taxonomic impediments and as a source of genetic information with which we could conduct phylogenetic estimates of diversity (PD). Diversity patterns elucidated with PD are often, but not always congruent with taxonomic estimates–and departures from these expectations can help clarify disturbance effects that are hidden from richness studies alone. We found that BIN richness and PD were greater in disturbed (forested) areas, however when we controlled for the expected relationship between PD and BIN richness, we found that cut sites contained less PD than expected and that this diversity was more phylogenetically clustered than would be predicted by taxonomic richness. While disturbance may cause an evident increase in diversity, this diversity may not reflect the full evolutionary history of the assemblage within that area and thus a subtle effect of disturbance can be found decades following forestry.

Communicating Environmental Health Risks with Indigenous Populations: A Systematic Literature Review of Current Research and Recommendations for Future Studies

ABSTRACT Indigenous populations are recognized as a group who are potentially vulnerable to environmental health hazards due to their intimate relationship with and reliance on local environments for aspects of culture, health, and well-being. In many circumstances barriers to effective communication and health risk management are linked to cultural, economic, and geographic factors. A systematic literature review was conducted to consolidate peer-reviewed research on the communication of environmental health risks with Indigenous populations. The comprehensive literature review procedures included searching databases and key journals that represented various fields in communication, environmental health, and Indigenous studies. The review yielded a total of 4,469 potential articles and a total of 13 of these manuscripts met the inclusion criteria. The 13 articles were analyzed to identify lessons learned for effective risk communication. Factors that influence successful risk communication strategies with Indigenous populations on this topic include: (1) developing messages that are congruent with the populations’ cultural beliefs and understanding of the environment; (2) including Indigenous populations in message design and delivery; (3) using credible and trustworthy spokespeople in message delivery; (4) identifying and utilizing effective communication materials and channels; and (5) ensuring that messages are understandable to the target audience. Gaps in the literature include the lack of longitudinal studies that empirically measure changes in perception, awareness and behavior, as well as a general lack of theory-based research. Results from this review provide directions for future work to help guide the development of more effective health risk communication research and strategies with Indigenous populations.

Gendered citizenship and the individualization of environmental responsibility: evaluating a campus common reading program

Abstract Campus common reading programs are intended to stimulate critical thinking and dialogue across disciplines yet scarce evidence exists to evaluate the success of such programs. We assess the extent to which engagement in an environmentally-themed common reading program is related to (1) concern for waste-related issues, (2) beliefs that addressing waste is an individual responsibility, and (3) individual behaviors intended to reduce personal waste. Results are drawn from a sample of undergraduate students (n = 398) with varying levels of engagement in the common reading program. Students who participated in the common reading program have higher levels of concern for waste than those who did not, are more likely to locate responsibility for addressing the problem of waste on the individual, and self-report higher frequency of engagement in individual efforts to reduce waste. We conclude with recommendations for further developing the critical thinking capacity of campus common reading programs.
