Environmental policy instruments and their effects on innovation

The influence of environmental policy on innovative behaviour of companies has so far received little attention in scientific discourse. Based on recent literature, the paper analyzes the impact of requirements, levies, permits, liability laws, and the EC‐eco‐audit regulation with respect to the generation of environmentally benign innovations. Most theoretical studies come to the conclusion that direct requirements provide little incentives for dynamic effects and that emission taxes and permits are better instruments to promote innovations. However, the empirical studies show that the dynamic effects of environmental policy instruments in practice partly differ from the ideal instruments analyzed in theoretical studies.     

Combined Pb–Sr isotopic analysis in provenancing late Roman iron raw materials in the territory of Sagalassos (SW Turkey)

In early Roman times, iron was likely supplied to the city of Sagalassos through the smelting of close-by hematite ores. In the early Byzantine period, magnetite–titanite placer sands in some instances could have been exploited for its iron. For the intermediate late Roman period, however, the source of the locally used iron was unknown. Pb and Sr isotopic analyses of iron ores from the area of Camoluk, just south of the territory of Sagalassos, and of late Roman iron artefacts from the antique city itself, reveal a very close resemblance. This makes the use of the Camoluk ores to supply Sagalassos with raw iron in the late Roman period likely. It is also shown that combined Pb and Sr isotopic analyses provides a powerful tool to distinguish chronological groups of iron provenance and a technique that can determine the nature and source of iron raw materials used.     

The Environmental Performance of Participatory and Collaborative Governance: A Framework of Causal Mechanisms

Many have advocated for collaborative governance and the participation of citizens and stakeholders on the basis that it can improve the environmental outcomes of public decision making, as compared to traditional, top‐down decision making. Others, however, point to the potential negative effects of participation and collaboration on environmental outcomes. This article draws on several literatures to identify five clusters of causal mechanisms describing the relationship between participation and environmental outcomes. We distinguish (i) mechanisms that describe how participation impacts on the environmental standard of outputs, from (ii) mechanisms relating to the implementation of outputs. Three mechanism clusters focus on the role of representation of environmental concerns, participants' environmental knowledge, and dialogical interaction in decision making. Two further clusters elaborate on the role of acceptance, conflict resolution, and collaborative networks for the implementation of decisions. In addition to the mechanisms, linking independent with dependent variables, we identify the conditions under which participation may lead to better (or worse) environmental outcomes. This helps to resolve apparent contradictions in the literature. We conclude by outlining avenues for research that builds on this framework for analysis.     

We are never alone: a conversation on bio art with Eduardo Kac

Brazilian-born artist Eduardo Kac’s (Rio de Janeiro, 1962) work has raised eyebrows especially for his ‘transgenic art’ projects, among others: Genesis, 1999; GFP Bunny, 2000; The Eight Day, 2001; Natural History of the Enigma, 2003/08. In all of these, Kac and his scientific collaborators realize genetic interventions into living organisms at the same time as they trigger audience reactions to these from playful kinds of interaction that is integrated into the works’ open and dynamic creative process. Yet whereas the ethical and political challenges Kac’s work poses have sparked lively debates within and beyond the realm of the arts – can and must art engage with the ‘creative’ potentials of biotechnology and genetics? Do these not in fact (as Vilém Flusser and others have suggested) hold the key to realizing the vanguardist dream of merging art and life? Or should the artist, from the vantage point of his own creative practice, not rather warn us against the ethical and political risks involved in genetic engineering? – much less attention has been paid to the way Kac’s art also continues and transforms a particular legacy of post-concretist, ambient and performance art in Latin America.

Kac himself has referred to Brazilian artists Flávio de Carvalho, Hélio Oiticica and Lygia Clark as informing his interest in open, participative forms, which characterize both his transgenic and his earlier ‘tele-presence’ art projects. Other Latin American artists of the late twentieth and early twenty-first century have been producing intriguing engagements with living materials, multispecies habitats and organic remains, including such diverse names as Luis Fernando Benedit, Nicola Constantino, Nuno Ramos, or Teresa Margolles. In a conversation with Jens Andermann and Gabriel Giorgi at the University of Zurich’s Center of Latin American Studies on March 12, 2015, Kac addressed the way in which his work might be seen as continuing or challenging long-standing representations of the New World as a repository of ‘nature’, from colonial chronicles of discovery to contemporary discourses of biodiversity and conservation. To what extent is bio art – and the questions it raises about the Anthropocene as a threshold of radical biopolitical convergence between ‘history’ and ‘nature’ – necessarily ‘transcultural’ and planetary in its extension?     

Political Regulation and the Strategic Production of Space: The European Union as a Post‐Fordist State Spatial Project

This article addresses the spatial differentiation of statehood in the process of European integration, looking at its consequences for the reorganization of political rule. First, we elaborate our theoretical foundations resting in materialist theories of the state. It is argued that hitherto analytical approaches have hardly been able to systematically integrate the societal generation of space. This shortcoming is addressed by drawing on theories of space discussed in radical geography. Second, we trace the spatial transformation of statehood in the EU. Our assertion is that the latter is characterized by the emergence of a multi‐scalar ensemble of state apparatuses. Finally, we discuss the implications of this transformation for the reproduction of domination. We assume that the multi‐scalar form of statehood offers a significant basis for the emergence of authoritarian forms of politics in the EU. At the same time, social conflicts over the political design of the EU are intensifying.     

Shared rivers and interstate conflict

“The previous war in the Middle East was about oil, the next war will be about water.” Such predictions have been made regularly, and particularly with reference to the possibility of upstream–downstream conflicts in major rivers which cross interstate boundaries. A good case can be made that competition over water resources may exacerbate conflict and contribute to interstate violence. More than 200 river systems are shared by two or more countries. Many rivers run between countries with a history of conflict, where water plays an important part in the economic life of the country. The dramatic statements about ‘water wars’, however, have a weaker foundation. As resource optimists have pointed out, there is an abundance of water where it is not subject to wasteful uses, human ingenuity can overcome water shortages, and nations can cooperate rather than fight to resolve international water issues. This study is built on newly generated data on boundary-crossing rivers, which have been added to the Correlates of War contiguity dataset. Our results indicate that a joint river does indeed increase the probability of militarized disputes and armed conflict over and above mere contiguity. This risk factor is comparable in size to standard control variables, but much smaller than the effect of contiguity itself. Water scarcity is also associated with conflict, and the upstream/downstream relationship appears to be the form of shared river most frequently associated with conflict. But these results are not very strong and we do not have any systematic data on the issues involved in the shared-river conflicts.
