社会环境道德价值观发展阶段与可持续发展

社会环境道德价值观是人们对人与自然环境道德关系的一种普遍的社会意识，它作为环境意识的核心内容，决定着人们的环境行为取向。当前我国社会环境道德价值观发展正处于从传统人类中心主义向现代人类中心主义的转变阶段。为实现我国可持续发展目标，社会环境道德价值观尚须由现代人类中心主义阶段向生存系统协调论阶段迈进。     

Climate Communications: Conflicts and Opportunities

The occasion for this forum was sparked by a front-page story in the New York Times by John M. Broder entitled, “Seeking to Save the Planet, with a Thesaurus” (May 1, 2009, p. A11). The article focused on the non-profit EcoAmerica's report, “Climate and Energy Truths: Our Common Future,” which shares research on communication approaches to engaging climate change and energy issues. The Broder article included commentary from Robert J. Brulle, Professor of Sociology and Environmental Science at Drexel University. In response, George P. Lakoff, Professor of Cognitive Science and Linguistics at UC-Berkeley, published an essay in The Huffington Post, “Why Environmental Understanding, or ‘Framing,’ Matters: An Evaluation of the EcoAmerica Summary Report” (May 19, 2009). The discussion about this report and differing approaches to environmental communication continued on blogs, in emails, and through various other forums. The editorial leadership team of this journal thought such prominent attention to environmental communication in the nexus of so many disciplines and professional investments was exciting. We are pleased the following scholars and practitioners are willing to elaborate on the stakes of this discussion in this forum.     

Blogging for Sustainability: The Intermediary Role of Personal Green Blogs in Promoting Sustainability

The rise of social media radically broadens the sources and platforms used for environmental communication. Especially personal green blogs are worthy of study as they are spaces of everyday cultural politics through which people make sense of sustainability issues, and because they entail a radical break from conventional media in terms of legitimacy, form, and content of environmental communication processes. This paper studies the representation of sustainability on personal green blogs, and the communication processes through which these representations are constructed. It does so through a qualitative study of Swedish-language blogs. We study three blogs in-depth: a living experiment blog on sustainable food practices; a lifestyle blog centered around green family life; and a blog about consuming green beauty products. The analysis shows that all three blogs translate the complex landscape of sustainability to individual everyday practices. Yet, what these sustainability practices entail differs considerably between the blogs, ranging from a-political and doable lifestyle choices to an onset to radical redefining of consumption. Also, the communication processes on the blogs differ in quality and quantity. The paper uses these insights to reflect on the debates about how environmental communication is shaped by blogging and social media practices.     

Flood risk and climate change in the Rotterdam area,The Netherlands: enhancing citizen's climate risk perceptions and prevention responses despite skepticism

Effective communication about climate change and related risks is complicated by the polarization between “climate alarmists” and “skeptics.” This paper provides insights for the design of climate risk communication strategies by examining how the interplay between climate change and flood risk communication affects citizens’ risk perceptions and responses. The study is situated in a delta area with substantial geographic variations in the occurrence and potential impact of flood risk, which has led to initiatives to make the area more “climate proof.” We developed a research model that examines individual differences in processing information about climate change related flood risk, based on the postulate that individuals often make an implicit trade-off between motivation to know “what is real” and motivation to maintain prior beliefs. A field experiment, embedded in a survey (n = 1887), sought to test out how the participants responded to risk frames in which a story on flood was either or not combined with climate change information. The results show that it was possible to increase the participants’ local climate risk perception in combination with increased motivation for flood damage prevention, despite a certain level of climate change skepticism. A general implication of our study is that relevant and diagnostic information about local climate-related flood risks can stimulate citizens’ need to know “what’s real” and their willingness to take responsibility for preparedness.     

Baudrillard and Our Destiny with the Natural World: Fatal Strategies for Environmental Communication

Drawing on the writings of Jean Baudrillard, the purpose of this essay is to suggest a set of communication practices that promote a different way of thinking about the earth–human relationship. Baudrillard's “fatal strategies” are developed into concepts of intersubjectivity, seduction, and sorcery, which when used in conjunction with more traditional, logical rhetorical appeals, can produce powerful appeals for environmental change. To illustrate, we explore how these strategies are used in two exemplars of environmental discourse: Rachel Carson's Silent Spring and Al Gore's documentary, An Inconvenient Truth.     

Chemical Controversy: Canadian and US News Coverage of the Scientific Debate about Bisphenol A

This study analyzes how newspapers covered the scientific controversy surrounding the health effects of exposure to Bisphenol A (BPA). Specifically, it examines whether framing, sources of scientific information, and balancing of competing sides in the debate differed across national political contexts and journalistic approaches. In regard to the former, it compares coverage in Canada (represented by the Globe and Mail), which had banned BPA in baby bottles and cups, to coverage in the United States (represented by the New York Times and Washington Post), which had not. In regard to the latter, it compares coverage in two US newspapers that took a conventional journalistic approach (the New York Times and Washington Post) to coverage in a US newspaper that launched an investigative series regarding BPA (the Milwaukee Journal Sentinel). The study concludes by considering what the findings suggest about how social forces shape coverage of scientific controversies involving environmental issues.     

Food for Thought: Audience Engagement with Sustainability Messages in Branded Content

Branded platforms are a growing “gray-zone” of marketing and media messages, in which corporations and news journalists partner to create content that supports strategic corporate goals while aligning with a publication’s scope of editorial coverage. As corporations are key influencers of and contributors to environmental communication, this trend has the potential to change environmental dialogue. In this article, we closely examine messages about food and sustainability, created in partnership by Chipotle Mexican Grill and the Huffington Post news site. We illustrate how use of a branded platform expanded the scope of environmental topics, issues, and frames that Chipotle addresses, how frames identified here connect to frames in coverage of science-related issues, as identified by other scholars, and discuss how branded platforms allow corporations to draw attention to polarizing environmental issues while protecting stakeholder relationships and brand reputation.     

Reform,Justice, and Sovereignty: A Food Systems Agenda for Environmental Communication

Food ecologies and economies are vital to the survival of communities, non-human species, and our planet. While environmental communication scholars have legitimated food as a topic of inquiry, the entangled ecological, cultural, economic, racial, colonial, and alimentary relations that sustain food systems demand greater attention. In this essay, we review literature within and beyond environmental communication, charting the landscape of critical food work in our field. We then illustrate how environmental justice commitments can invigorate interdisciplinary food systems-focused communication scholarship articulating issues of, and critical responses to, injustice and inequity across the food chain. We stake an agenda for food systems communication by mapping three orientations—food system reform, justice, and sovereignty—that can assist in our critical engagements with and interventions into the food system. Ultimately, we entreat environmental communication scholars to attend to the bends, textures, and confluences of these orientations so that we may deepen our future food-related inquiries.     

The Country,the City,and the Corporation: Rio Tinto Kennecott and the Materiality of Corporate Rhetoric

Contributing to extant discourses about corporate environmental advocacy, this paper argues that corporations can embed discursive rhetorical strategies in material places and spaces. This argument contributes to environmental communication by bridging divisions between discursive and materialist approaches to corporate rhetoric. Corporate materiality is realized in the study of Rio Tinto Kennecott (RTK) at places of corporate community where RTK enunciates a dominant environmental discourse about the necessity of the Bingham Canyon Mine through strategies such as the technological shell game, the hypocrite's trap, and corporate heterotopia, which are made manifest materially alongside cultural values such as epistemic trust, technological progress, community, and home. Using participatory critical rhetoric as a methodology, I analyse RTK's material rhetoric at the Natural History Museum of Utah, the Rio Tinto Soccer Stadium, and the Daybreak suburban community. This case study reveals that corporations are assemblages that assert many different, and sometimes competing, arguments that can deflect environmental criticism, materially.     

Measurement and Meaning in Environmental Communication Studies: A Response to Kassing,Johnson, Kloeber,and Wentzel

This essay represents an invited editorial response to Kassing, Johnson, Kloeber, and Wentzel's “Development and Validation of the Environmental Communication Scale” in Environmental Communication: A Journal of Nature and Culture. Kassing and his associates use an apt review of the status of the environmental communication field as the basis for developing a protocol and instrument to measure the actual practice of engaging environmental subject matter in daily life. Although their factor analytic work is laudable in its intent, their approach to empirically exploring environmental communication in action further institutionalizes a number of conceptual and methodological shortcomings in our discipline. In particular, what researchers and respondents think constitutes “environmental” content per se poses a significant barrier to using the proposed tool in applied settings. After critiquing the Kassing et al. work in terms of a number of issues related to the validity and reliability of their research, I conclude by suggesting that the research may provide a needed springboard for exploring the dynamics of interpersonal settings that mediate important dialog and action regarding the environment.     

“A Short Burst of Inconsequential Information:” Networked Rhetorics,Avian Consciousness,and Bioegalitarianism

This essay uses the concept of “avian consciousness” to reconsider assumptions about human communication and theorize networked rhetorics. By adopting an ornithomorphic frame, I critically read Don DeLillo's The Body Artist as an exploration of overlaps between human and avian consciousness. I then argue that avian consciousness provides a richer metaphor for understanding networked rhetorics than autistic consciousness, which is an increasingly dominant trope for explaining interaction with digitally networked media. I explore how Twitter, explicitly modeled on avian communication, can be understood as circulating information in ways analogous to the contact and assembly calls of birds. The essay concludes by noting that seeing avian features in human communication diminishes the perceived gap between human and nonhuman animal, holding out hope for a more bioegalitarian relationship between species.     

The Nature of Time: How the Covers of the World's Most Widely Read Weekly News Magazine Visualize Environmental Affairs

Scholars of environmental communication acknowledge the importance of visual representations in shaping perceptions and actions in relation to environmental affairs. Unlike with other media, including newspapers, television and film, research on the visualization of nature and environmental issues in magazines is rare. This study focuses on the covers of Time magazine, one of the world's most influential news weeklies. A dataset that includes all relevant covers from 1923 to 2011 is examined using a combination of quantitative and qualitative content analysis to analyze the visual representation of nature and environmental issues. The results show that the presence of environmental issues and nature on the covers has increased over the decades. Furthermore, Time takes an advocacy position on some environmental issues, but it is a shallow one that is weakly argued through less-than-engaging imagery and fails to offer much in the way of solutions or agency to the reader.     

Scapegoat Ecology: Blame,Exoneration, and an Emergent Genre in Environmentalist Discourse

This essay identifies and examines scapegoat ecology, an emergent genre in online environmental discourse. In scapegoat ecology, a public of environmentally minded individuals focuses attention and vitriol on a single person for being particularly harmful to the environment. This essay argues that such discourse deflects attention from more complex and systemic environmental factors and implicitly exonerates the broader community, assuring it of its own environmental commitments while excusing it from further ecological action. The essay describes the form and appeal of scapegoat ecology, then provides a series of illustrative case examples before highlighting the implications of such discourse for both environmental communication and broader social/political conversations.     

The Flood Myth in the Age of Global Climate Change

When released, The Day After Tomorrow was widely described by critics and the movie's creators as a pro-environmentalist film. This essay argues that The Day After Tomorrow articulates a variation of apocalyptic discourse identified as a flood myth. The authors conclude that this version of the flood myth largely undermines contemporary environmental discourse that attempts to generate public activism in addressing ecological problems, by replacing an emphasis on human efficacy with symbolic vindication and exchanging collective effort for individual survivalism. The film thus serves as a cautionary tale about the potential consequences of contemporary mythic discourse presented as supporting environmental activism.     

Reconnecting with nature for sustainability

Calls for humanity to ‘reconnect to nature’ have grown increasingly louder from both scholars and civil society. Yet, there is relatively little coherence about what reconnecting to nature means, why it should happen and how it can be achieved. We present a conceptual framework to organise existing literature and direct future research on human–nature connections. Five types of connections to nature are identified: material, experiential, cognitive, emotional, and philosophical. These various types have been presented as causes, consequences, or treatments of social and environmental problems. From this conceptual base, we discuss how reconnecting people with nature can function as a treatment for the global environmental crisis. Adopting a social–ecological systems perspective, we draw upon the emerging concept of ‘leverage points’—places in complex systems to intervene to generate change—and explore examples of how actions to reconnect people with nature can help transform society towards sustainability.     

It is Always Dry Here: Examining Perceptions about Drought and Climate Change in the Southern High Plains

ABSTRACT

Drought is defined, experienced, and communicated about in multiple ways. This case study examines individual definitions of drought (timing, impacts, and severity) and attitudes about climate change. Household surveys (n?=?120) were conducted in Cimarron County, Oklahoma and Union County, New Mexico using a stratified random sampling method to select farmers, ranchers, and town residents. Information about drought is primarily communicated between neighbors, friends, and family, as well as media and local governing agencies. Residents perceive the recent drought to be the worst drought on record, regardless of previous drought experiences. Residents reported widespread drought-related impacts on agriculture, environment, and society. Most residents see drought as cyclical and driven by natural causes, rather than human causes. We recommend adaptive drought communication engage more fully with identity, place, and history. Climate information should be presented in a relevant manner to diverse agricultural stakeholders with differing attitudes about climate change, management, and climate information.     

Comparing computing formulas for estimating concentration ratios

The purpose of this paper is to provide guidance on the choice of computing formulas (estimators) for estimating average concentration ratios and other ratio-type measures of radionuclides and other environmental contaminant transfers between ecosystem components. Mathematical expressions for the expected value of three commonly used estimators (arithmetic mean of ratios, geometric mean of ratios, and the ratio of means) are obtained when the multivariate lognormal distribution is assumed. These expressions are used to explain why these estimators will not in general give the same estimate of the average concentration ratio. They illustrate that the magnitude of the discrepancies depends on the magnitude of measurement biases, and on the variance and correlations associated with spatial heterogeneity and measurement errors. This paper also reports on a computer simulation study that compares the accuracy of eight computing formulas for estimating a ratio relationship that is constant over time and/or space. Statistical models appropriate for both controlled spiking experiments and observational field studies for either normal or lognormal distributions are considered. Our results indicate that for either type of study the geometric mean is generally preferred if the lognormal distribution applies. However, the geometric mean has the disadvantage that its expected value depends on n, the number of measurements taken. Ricker's estimator, $\text{R}\text{?}{}_{\mathrm{rt}}$, appears to perform worse than the other estimators studied when the observations are lognormal. All eight estimators appear to be equally accurate for the controlled spiking study when data are normally distributed. For observational field studies when data are normally distributed the ratio of means or slight modifications thereof are preferred to other estimators investigated. Before one chooses a computing formula for estimating a concentration ratio, thought should be given to what target value needs to be estimated to satisfy study objectives, and to whether the normal or lognormal distribution is a more realistic model. The geometric mean performs well for lognormal distributions, but comparison of geometric means or of a geometric mean with environmental limits can be misleading if n is small. The arithmetic mean of ratios is a conservative choice in that it will always give a larger estimate than will the geometric mean. It may also be severely biased when data are lognormal and the variances of measurement errors are large. The ratio of the means is a reasonable choice if the distribution is normal. The median of the observed ratios, $\text{R}\text{?}{}_{\mathrm{<mtext>md</mtext>}}$, is useful estimate since it is easily obtained and has an easily understood interpretation as the point above which and below which 50% of the observed ratios lie. Also, it is appropriate no matter what the distribution of the observed ratios may be. Confidence limits on the median are also easily obtained. Finally, while this paper emphasizes applications in radionuclide research, our results should be applicable to a wide range of environmental contaminants since many contaminants have approximately lognormal distributions.     

Integrating Media Studies of Climate Change into Transdisciplinary Research: Which Direction Should We Be Heading?

Research in the area of media coverage on climate change communication represents one of the most prolific areas of inquiry within communication and mass communication studies. This body of literature, which ranges from empirical to critical studies, continues to expand. Much research has focused on representations of climate change causes, effects, and human actions, while some has assessed the impacts of these representations. What is broadly missing from this literature, however, is a discussion of how we might integrate media analysis into transdisciplinary collaborative research aimed at creating solutions to the social, environmental, and economic issues intertwined with climate change. Given the magnitude of problems the society and science are currently grasping with, it behooves us to understand how media studies can contribute most effectively to characterizing and solving problems. We maintain that the move toward integrating media studies into transdisciplinary collaborative research marks an essential transition for environmental communication in general, but climate change communication in particular, given the urgency and magnitude of creating meaningful adaptation and mitigation strategies to address this pressing, complex challenge. Drawing on our work as part of a large transdisciplinary sustainability science team, we provide a case study for understanding what collaborations are key to moving media studies into a transdisciplinary context and the key opportunities and barriers that come along with that move. We argue that media studies must increasingly engage directly in collaboration with other researchers, stakeholders, and communities to serve on-the-ground decision-making and enhance society's ability to take action.     

Conservatism vs. conservationism: differential influences of social identities on beliefs about fracking

ABSTRACT

Although recent expansions in hydraulic fracking operations across the United States have led to greater news coverage and attention from the public, overall understanding remains fairly low. For some, relevant social identities, including environmental or political, may provide a short cut to becoming informed about fracking, or to determining what they believe about it and how that influences their positions on fracking policies. Social identity influence frameworks provide an approach to understanding the relationships between belief and identity, which this study investigates through its affiliational and attitudinal components. National survey data are used to model pathways from environmental and political identities to beliefs about risks associated with fracking. Environmental attitudes significantly predicted belief that fracking has health risks, and mediated a relationship from environmental group affiliation, but environmental information was not significant. Ideology had direct and indirect effects, through partisan media use, while partisanship had direct effects on beliefs about environmental risks.     

Citizens’ perception of the resilience of Australian cities

How well does the general public understand the concept of urban resilience? We address this question via an online survey of 500+ citizens living in three large Australian cities (Sydney, Melbourne and Perth). The majority of respondents claim not to know what urban resilience means. Of the remaining respondents, understanding ranges from poor to sophisticated. To circumvent this stated lack of understanding, we cast the concept of urban resilience into a more familiar framework consisting of risk and ability to cope with threats. This allows us to assess perceptions about what may challenge the resilience of Australian cities. Two concerns clearly emerge: (1) violence and social unrest and (2) environmental threats. Analysing a number of constructs from the social psychology literature reveals that these two concerns hold different cognitive signatures, whose understanding may facilitate discussion and communication within a public engagement process.
