Public values for energy system change

In this paper we discuss the importance of framing the question of public acceptance of sustainable energy transitions in terms of values and a ‘whole-system’ lens. This assertion is based on findings arising from a major research project examining public values, attitudes and acceptability with regards to whole energy system change using a mixed-method (six deliberative workshops, n = 68, and a nationally representative survey, n = 2441), interdisciplinary approach. Through the research we identify a set of social values associated with desirable energy futures in the UK, where the values represent identifiable cultural resources people draw on to guide their preference formation about particular aspects of energy system change. As such, we characterise public perspectives as being underpinned by six value clusters relating to efficiency and wastefulness, environment and nature, security and stability, social justice and fairness, autonomy and power, and processes and change. We argue that this ‘value system’ provides a basis for understanding core reasons for public acceptance or rejection of different energy system aspects and processes. We conclude that a focus on values that underpin more specific preferences for energy system change brings insights that could provide a basis for improved dialogue, more robust decision-making, and for anticipating likely points of conflict in energy transitions.     

Designation of marine protected areas in Belgium: A legal and ecological success?

In Belgium a long process (1999–2005) led to the designation of several marine protected areas (MPAs). In order to analyse the designation process, the ‘policy arrangement approach’ was used as an analytical tool. Attention was given to four dimensions (actors and coalitions, arguments, rules and resources). Particular attention was paid to the switch from an authoritative to a more deliberated policy style in reaction to conflicts with stakeholders. This switch in policy style contributed to a successful legal designation, but does not guarantee the best protection of marine biodiversity. This case study linked science (setting ecological goals) to policy (analysis of a policy process) and led to some more general conclusions on the designation of MPAs and the role of participation in this process.     

The creative reconstruction of the Internet: Google and the privatization of cyberspace and DigiPlace

The Internet has often been portrayed as the ultimate leveler of information where existing hierarchies of power and privilege are undermined by meritocracy. Some websites and functions are, however, more equal than others. In particular, search engines such as Google have been a key means to construct meaning out of disorder. This ordering (or enclosing of the Internet commons), however, comes at a cost as a location within the top 10 Google search results, marks the boundary (albeit a fluid one) between the core and the periphery of the Internet. The recent incorporation of spatial elements into the Google indexing raises fresh and geographically relevant concerns. This article focuses on the construction, access and use of Google derived rankings to deploy geo-referenced information in the physical environment and the way this melding of code and place affects how people interact with place. Using the theoretical concept of DigiPlace this article analyzes how Google Maps and Google Earth are structured and shape what appears (and what does not) in cyberspace and DigiPlace. Of particular concern are the implications of a private corporation controlling this new space.     

Promoting geodiversity: learning lessons from biodiversity

Progress made in promoting geodiversity in recent times is reviewed, concluding that it is now an established component of the Earth Sciences. However, it still lacks the status and standing of biodiversity in governmental, political and public forums. The paper assesses what can be learnt from the experience of the development and promotion of biodiversity. Based on this experience, eight suggestions for increasing the understanding and ownership of geodiversity beyond the Earth science community are provided as a basis for discussion.     

City of the Spectacle: White Night Melbourne and the politics of public space

Public policy frequently is utilised as a medium to facilitate or restrict access to public space, and to privilege economic priorities. In this context urban arts festivals are used as a means to generate dominant narratives of place and use of public space. Urban arts festivals generate spaces of spectacle and wonder, and are often used as marketing strategies to revitalise urban economies and differentiate cities one from another on the global stage, engendering a commodification of place. The present paper explores this tension through an examination of the role of urban arts festivals in spatial politics. White Night Melbourne is the first Australian iteration of the Nuit Blanche International, an international network of all-night arts festivals. It is used as a case study to explore the impact of an urban arts festival on the spatial politics of Melbourne. A theoretical basis is established using the frame of Guy Debord's ([1967] 1994) The Society of the Spectacle, as well as the concepts of ‘assemblage’ and ‘expressivity’.     

GIS的社会化及公众GIS

GIS(地理信息系统 )的发展继专业化和行业化阶段之后 ,正处于社会化发展阶段。在该阶段 ,GIS的主要作用是为公众提供信息服务。文章在分析了GIS的这种发展趋势的基础上提出了“公众GIS”的概念 ,即 :直接面向公众 ,为公众提供信息服务和辅助公众进行行为决策的地理信息系统。与传统GIS相比 ,公众GIS更具有信息服务业的特点。公众GIS的建设应该突出信息的全面性、现势性和准确性、系统的友好性以及数据的易维护性等原则。公众GIS的关键技术包括数据采集、网络、数据库、多媒体以及系统的友好性设计等技术。公众GIS在建设全国城市公众信息服务网、全国交通旅游信息网以及汽车导航信息系统等方面具有广阔的应用前景。文章对公众GIS的实例———“今日武汉”公众查询系统作了简要介绍。     

Knowing wildfire risk: Scientific interactions with risk mitigation policy and practice in Victoria,Australia

Over the past decade, major landscape wildfires (or ‘bushfires’ in Australia) in fire-prone countries have illustrated the seriousness of this global environmental problem. This natural hazard presents a complex mesh of dynamic factors for those seeking to reduce or manage its costs, as ignitions, hazard behaviour, and the reactions of different human and ecological communities during and after hazard events are all extremely uncertain. But while those at risk of wildfire have been subject to significant research, the social dimensions of its management, including the role of science, have received little attention. This paper reports on a case study of the Barwon-Otway area of Victoria in Australia, a high wildfire risk area that has recently been a pilot site for a new risk mitigation strategy utilising the wildfire simulation model PHOENIX RapidFire. Against simple equations between ‘more science’ and ‘less uncertainty,’ this paper presents results from interviews and a workshop with practitioners to investigate how scientific research interacts with and informs both wildfire policy and practice. We suggest that attending to cultural and social specificities of the application of any technical innovation—such as next generation modelling—raises questions for future research about the roles of narrative, performance, and other knowledges in the sedimentation of science.     

Improving marine environmental health through marine citizenship: A call for debate

This paper presents an evaluation of the role of marine citizenship in improving marine environmental health and marine governance. Marine citizenship describes the rights and responsibilities of an individual towards the marine environment, which support the achievement of marine policy objectives at the national level. It is argued that marine citizenship requires an enhanced awareness of marine environmental issues, an understanding of the role of personal behaviour in creating and resolving marine environmental issues, and a shift in values to promote marine pro-environmental behavioural choices. It is concluded that the value shift is likely to be produced by the development of an altered relationship between the state and the individual, in which the expectations placed on citizens by the state are extended to include marine pro-environmental behaviour. The paper is intended to stimulate debate and the authors invite and encourage replies to the ideas contained within the paper.
