The political ecology of water metabolism: the case of the Cobre las Cruces copper mine,southern Spain

Access to extractive resources relies as much on technology and prices as it does on the power to designate ecological and economic meanings to water and other environmental goods. This paper examines the ways in which the mining industry uses scientific models to create meanings for water that in turn legitimizes their access to and control over it. To do so, this paper explores the relevance of combining biophysical analyses—in this case water metabolism—with an examination of those power relations and social constructions that coexist with and affect the flows of water. Based on empirical research, this paper analyzes the evolution of water management in the process of copper production at the Cobre las Cruces mine in southern Spain to identify present contradictions in the strategies adopted by the mining company to avoid water degradation. These contradictions are revealed by examining how water has been framed as a resource not susceptible to being used for purposes other than mining processes. We argue that those framing this environmental explanation—the regional government and the mining industry—are promoting net subtractions of water from an aquifer against current regulations.     

Unravelling the Threads: Discourses of Sustainability and Consumption in an Online Forum

This article analyzes an online discussion that followed an article published by UK environmental activist and journalist George Monbiot in The Guardian online newspaper. The analysis addresses the ways in which participants in an online forum debate responded to the tensions and contradictions between lifestyle, consumption, and sustainability highlighted in the original article. The discursive construction of class, green political orientations, and identities; visions of “the good life”; and appeals to religion and science are highlighted throughout the analysis—as are the discursive strategies for positioning self, other, and audience in the debate. The argument emphasizes the heterogeneity of discursive positioning and reflects on the role of social media in the politics of consumption and sustainability, especially given the inherent reflexivity of web forums as online communicative forms.     

An integrated analysis of production costs and net energy balance of biofuels

Up to now, the “low” price of oil has prevented the development of alternative fuels but with the current high price and increasing scarcity, biofuels could become an economically attractive alternative. However, the economic assessment of biofuels has to take into account total production costs, including impact on agriculture, and the energy balance of first generation alternative fuels (biodiesel and bioethanol). Moreover, plans to produce biofuels from agriculture should not be achieved without considering the latest developments and reforms of the common agricultural policy, which promotes a change towards sustainable rural development based on multifunctional agriculture. From the analysis carried out, it emerges that first generation biofuels do not seem to be the best solution because of high production cost, limited land availability and low net energy balance. Furthermore, only a small quantity of biofuels can be produced as alternative to fossil oil because an incremental production will lead to the rising of agri-food prices. Only second generation biofuels could be a possible solution, although they still require much supplementary research and analysis.     

Goshute Native American Tribe and Nuclear Waste: Complexities and Contradictions of a Bounded-Constitutive Relationship

This essay examines discourse from members of the Skull Valley Goshute Native American tribe about the nuclear-waste proposal and tribal controversy. Building from Kinsella's “bounded-constitutive” theoretical model of communication, I argue the environment (material) is more than a context where Goshute culture and policy development (symbolic) plays out. Rather, environment, culture, and policy mutually define each other, and the material environment constrains Goshute culture. Instead of the symbolic unilaterally influencing the material, the material responds and acts to influence the symbolic. The symbolic becomes responsible to the material and vice versa as the relationship is multi-influential and interactive creating political, cultural, and environmental complexities and contradictions while fueling intra-tribal conflict.

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.     

First-Person Effects of Emotional and Informational Messages in Strategic Environmental Communications Campaigns

This study examined the first- and third-person effects of emotional and informational messages, particularly relating to the critical issue areas of energy, the environment, and global warming. Due to intense political polarization on such issues, it also explored the role of political party identification. The results of an experiment indicated that informational messages about the environment produced third-person effects, while environmental advertisements meant to evoke emotion caused first-person effects. Moreover, emotional environmental advertisements appealed more to Republicans and those who did not support a political party. As such, indirect, emotional messages appear to represent an opportunity for strategic environmental communicators to design campaigns that resonate with potentially unreceptive audiences.     

Environment as Politics: Framing the Cerattepe Protest in Twitter

Environmental protests across the globe are often studied with a particular focus on their environmental aspects, but these protests are also embedded in a local political setting shaped by governmental policies. Recent environmental protests in Turkey, which appear to be based on ecological grievances, have developed as a response to political decisions that gave priority to economic development and national interests over environmental concerns. This study examines the political character of the environmental protest in Cerattepe, and focuses on the framing practices of its players in order to see if their motivations transcended environmental concerns. The research combines framing with network analysis, and studies the propagation of frames through Twitter. It has been found that the political economic aspects became predominant in the protest network, while the frames fostered dense connections between activist groups.     

The ‘New Water Culture’ on the Web: an issue network analysis

In this article, we analyse how the Internet is used to bring visibility to water affairs. We focus on the way different organisations exploit the Web in order to participate in the debates about water policy in Spain and to define the topics concerned. To do this, we have drawn up an issue network articulated around an alternative and sustainable water policy called ‘New Water Culture’. We examine the composition of this web structure, its hyperlinking styles, key nodes and political trajectories. The outcomes indicate that the ‘New Water Culture’ has become a main frame in Spanish environmental policy. Supported both by governmental and non-governmental players, the ‘New Water Culture’ struggles between two opposing trends: its expulsion from the public sphere and efforts to open it up to scrutiny from political outsiders.     

Media Access and Political Efficacy in the Eco-politics of Climate Change: Canadian National News and Mediated Policy Networks

We use a discourse network analysis approach to answer two questions about national news coverage of climate change policy debate in Canada during the period 2006–2010. First, what is the media visibility of actors relevant to policy development and advocacy on climate change? Second, given the political and economic context of climate policy-making in Canada, does greater or lesser media visibility reflect effectiveness in climate policy advocacy? Multiple interpretive frameworks characterize Canadian political discourse about climate change, with fragmentation between the federal government, opposition political parties, provincial governments, and environmental organizations. Contrary to expectations, environmental organizations had high levels of media visibility while the relative invisibility of fossil fuel corporations was notable in the media coverage of Canadian climate discussions. Our findings challenge optimistic accounts of the relationship between media power and political power, and suggest that media power does not necessarily translate to political efficacy.     

Medieval London and its supply hinterlands

The essay reviews the impact of London??s demands for food, drink and fuel on the farming systems and specialisation in the regions from which it drew supplies. Focusing on the well-recorded period around 1,300, when London was a major but second-ranking European city, it makes comparisons with other European cities in the same period and with London in later centuries, as the city developed a world role. Despite its small size by modern standards, medieval London??s impact on its hinterland was distinct, dynamic, highly commercialised and extensive. It shaped rural landscapes and agrarian practices in ways which in key respects conform to modern theories of spatial specialisation. London??s environmental influence operated within an international context, where the opening up of distant resources could affect choices concerning specialisation in and close to the city. Demographic change and shifts in consumption arising from changing standards of living were also influential. This left a marked ??urban footprint?? in production, marketing and the generation of waste. Moreover, its distinctive political context influenced London??s attitude towards managing its supply chains, differentiating it from many of its European counterparts. Medieval observers recognised those landscapes and their connection with the city, but did not theorise them in present-day terms.

Towards implementation and achievement of sustainable biofuel development in Africa

Although sustainable bioenergy development in Africa is critically debated, if projects are developed within a credible framework, opportunities for sustainability arguably can arise. This paper presents research on the characteristics of sustainable biofuel projects as provided in the literature and according to expert opinions obtained by way of a survey involving thirty-eight international experts. Participants were selected for their expertise in the fields of environmental, social and economic sustainability relating to biofuels in Africa. The survey results suggest that projects which display a high degree of transparency, incorporate local stakeholder involvement, and ideally include local villagers as partners are more likely to achieve sustainable biofuel production. Experts also indicated that reconciling diverse stakeholder objectives alongside the principles of sustainable development remains an ongoing challenge. A process is recommended for sustainable biofuel development, which attempts to harmonise efficiency, stakeholder interaction and the integration of diverse stakeholder perspectives. To support the process, it is recommended that an advisory/mediating body that acts according to best practice principles would be of great assistance. Such an advisory/mediating body would be conversant with local land, social, economic and environmental conditions, project sustainability and administration, and also advise on biofuel framework educational needs.     

Layered neural networks based analysis of radon concentration and environmental parameters in earthquake prediction

A layered neural network (LNN) has been employed to estimate the radon concentration in soil related to the environmental parameters. This technique can find any functional relationship between the radon concentration and the environmental parameters. Analysis of the data obtained from a site in Thailand indicates that this approach is able to differentiate time variation of radon concentration caused by environmental parameters from those arising by anomaly phenomena in the earth (e.g. earthquake). This method is compared with a linear computational technique based on impulse responses from multivariable time series. It is indicated that the proposed method can give a better estimation of radon variations related to environmental parameters that may have a non-linear effect on the radon concentration in soil, such as rainfall.     

Rhetorical Recommendations Built on Ecological Experience: A Reassessment of the Challenge of Environmental Communication

This article reconsiders the challenge of environmental communication by inquiring into the fundamental rhetorical difficulty of thinking in terms of ecology. We discuss two essential yet bewildering aspects of ecology: its focus on interconnection and its use of multiple scales. On this basis, we distil six rhetorical recommendations: a shift from appealing to pre-existing values to avenues for transforming values; a shift from arguments from authority to addressing legitimate resistances; a shift from a focus on mutual agreement to a mutual bewilderment; a shift from intellectual comprehension to personal experience; a shift from negative effects to positive connections; and, finally, a shift from a focus on political results to local transformations. We experiment with this rhetorical approach through two applications: for critical reassessments of past articulations we consider the Gaia Hypothesis and Deep Ecology, and for current refinements to environmental problems we consider controversies around Marcellus Shale gas development     

The Influence of Media Use on Environmental Engagement: A Political Socialization Approach

Current research suggests that the media play an important part in informing and engaging citizens in environmental issues. Building on these findings, this study adopts a political socialization approach to citizens' involvement in everyday-life pro-environmental behavior. Multivariate analysis of recent survey data from Swedish adolescents (N = 1148) demonstrates direct as well as indirect relationships between frequency of news media use, talk about environmental issues with parents and peers, and extent of pro-environmental behavior. The findings are consistent with the notion that news media use promotes behavior by raising awareness of environmental issues. The results are also discussed in terms of a citizen-communication framework according to which interpersonal communication translates environmental information gleaned from news sources to adolescents' everyday-life reality, thereby motivating pro-environmental behavior. Future directions for examining causal mechanisms in more detail are discussed.     

Energy and environmental challenges: bringing together economics and engineering (ICEE’17)

Agricultural landscapes of the southern Brazilian Amazon are the result of 80 years of governmental policies to install a powerful agricultural sector. Yet, this rapid expansion raised important environmental considerations especially with regard to deforestation. The agricultural frontier is thus now facing a huge challenge: to combine socioeconomic development with environmental conservation in the context of frontier expansion. Based on a conceptual model of the agricultural frontier, we review historical changes in environmental and development policies in the Brazilian state of Mato Grosso and emphasize their ambivalent trend to both encourage and control the progress of the frontier. We then extend this model with an integration stage where environmental governance and economic development evolve from competing to complementary concepts. At this stage, the efforts to slow down deforestation are accompanied with programs to promote new agricultural practices and support industrialization. Finally, we put into perspective this recent evolution with regard to the underlying reasons for changing the agricultural model, thus considering the agricultural frontier to be at a tipping point where first positive results need to be confirmed in spite of an unstable economic and political situation.     

Indonesia’s Accidental Island: Composing the Environment in the Echo of Disaster

By presenting stakeholders’ competing representations of an extraordinary geological formation, an island with a surface that is comprised of runoff from an infamous mud volcano in East Java, this article explores the communicative openings and closures that arise during an environmental disaster. A particular concern is attuning communicative practices to the diverse human and nonhuman actors that not only produce disasters but also shape our understandings and responses to disasters. Drawing on the work of Bruno Latour, this article suggests that non-anthropocentric modes of inquiry present new communicative and political possibilities for pursuing both social justice and safe environments. While this article focuses on a specific set of incidents in Indonesia, this project develops tools and perspectives that can be applied to environmental conflicts at other places.
