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

Dirk Bogaert  An Cliquet  Frank Maes 《Marine Policy》2009,33(6):878

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.  相似文献   

2010—2015年中东北非政局变动中的“政治性民意势力”及其影响     

熊理然  刘保强  武友德  蒋梅英 《地理科学进展》2019,38(6):930-940

援引批判地缘政治学话语权和地缘政治想象分析方法,在对“民意”“政治性民意”“政治性民意势力”内涵界定的基础上,分析了2010—2015年中东北非地区相关国家政局变动中“政治性民意势力”的形成背景、过程及其影响。结果表明：中东北非国家“政治性民意势力”的形成有着深厚的国内背景和复杂的国际背景;“政治性民意势力”的形成经历了从民意事件客体的呈现,到民众聚集并上升为政治性议题,再到国内外势力借力博弈形成挑动抗议、推动政变的政治力量的过程;“政治性民意势力”形成以后,多行为体借力博弈下,在国别、区域上呈现不同的扩散轨迹和规律;“政治性民意势力”一方面造成了中东北非相关国家的政局变换,另一方面则推动区域地缘政治格局的变迁。这是对民意事件的地缘政治理论解读和分析,是一次较为有意义的尝试。  相似文献   

The public perception of carbon dioxide capture and storage in the UK: results from focus groups and a survey     

Simon Shackley  Carly McLachlan  Clair Gough 《Climate Policy》2013,13(4):377-398

Abstract

A series of meetings of two ‘Citizen Panels’ were held to explore public perceptions of off-shore carbon dioxide (CO₂) capture and storage (CCS). In addition, a face-to-face survey of 212 randomly selected individuals was conducted. We found that, on first hearing about CCS in the absence of any information on its purpose, the majority of people either do not have an opinion at all or have a somewhat negative perspective. However, when (even limited) information is provided on the role of CO₂ storage in reducing CO₂ emissions to the atmosphere, opinion shifts towards expressing slight support for the concept.

Support depends, however, upon concern about human-caused climate change, plus recognition of the need for major reductions in CO₂ emissions. It also depends upon CCS being seen as just one part of a wider strategy for achieving significant cuts in CO₂ emissions. A portfolio including renewable energy technologies, energy efficiency, and lifestyle change to reduce demand was generally favoured. CCS can be part of such a portfolio, but wind, wave, tidal, solar and energy efficiency were preferred. It was felt that uncertainties concerning the potential risks of CCS had to be better addressed and reduced; in particular the risks of accidents and leakage (including the potential environmental, ecosystem and human health impacts which might result from leakage).  相似文献   

Effects of economic recession and local weather on climate change attitudes     

Robert Y. Shum 《Climate Policy》2013,13(1):38-49

How are large companies responding to the challenges of reducing their greenhouse gas (GHG) emissions? An analysis of the published climate change policies and performance of 125 large European companies is presented. The results suggest that most large European companies have now developed the management systems and processes necessary for them to effectively manage their GHG emissions and related business risks. However, there is a significant disconnect between the targets that companies set for themselves and the more ambitious targets being set by the European Union (which has committed to a 20% reduction in its emissions by 2020 against a 1990 baseline). Of the companies surveyed, just over one-third had stabilized or reduced their total GHG emissions over the period 2002–2007, and fewer than one-third expected their emissions to stabilize or reduce in the coming years. The relationship between the quality of corporate policies and performance outcomes (in terms of GHG emissions) suggests that while companies with stronger policies are likely to have relatively better performance, only a minority of those companies with the highest-quality policies are committing to absolute reductions in their GHG emissions.  相似文献   

Politics eclipses climate extremes for climate change perceptions     

《Global Environmental Change》2014

Whether or not actual shifts in climate influence public perceptions of climate change remains an open question, one with important implications for societal response to climate change. We use the most comprehensive public opinion survey data on climate change available for the US to examine effects of annual and seasonal climate variation. Our results show that political orientation has the most important effect in shaping public perceptions about the timing and seriousness of climate change. Objective climatic conditions do not influence Americans’ perceptions of the timing of climate change and only have a negligible effect on perceptions about the seriousness of climate change. These results suggest that further changes in climatic conditions are unlikely to produce noticeable shifts in Americans’ climate change perceptions.  相似文献

The GeoCitizen-approach: community-based spatial planning – an Ecuadorian case study     

Karl Atzmanstorfer  Richard Resl  Anton Eitzinger  Xiomara Izurieta 《制图学和地理信息科学》2014,41(3):248-259

Over the last years, geospatial web platforms, social media, and volunteered geographic information (VGI) have opened a window of opportunity for traditional Public Participatory GIS (PPGIS) to usher in a new era. Taking advantage of these technological achievements, this paper presents a new approach for a citizen-orientated framework of spatial planning that aims at integrating participatory community work into existing decision-making structures. One major cornerstone of the presented approach is the application of a social geoweb platform (the GeoCitizen platform) that combines geo-web technologies and social media in one single tool allowing citizens to collaboratively report observations, discuss ideas, solve, and monitor problems in their living environment at a local level. This paper gives an account of an ongoing participatory land-zoning process in the Capital District of Quito, Ecuador, where the GeoCitizen platform is applied in a long-term study.  相似文献   

Promoting geodiversity: learning lessons from biodiversity     

Roger Crofts 《Proceedings of the Geologists' Association. Geologists' Association》2014

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.  相似文献   

面向不同用户群体的社交媒体台风舆情演化分析及对比研究     

金城  吴文渊  陈柏儒  杨续超 《地球信息科学学报》2021,23(12):2174-2186

社交媒体数据可以为台风灾害追踪、灾时救援和灾情评估提供及时有效的信息。现有研究常采用主题建模和情感分析等技术对台风期间社交媒体平台（如新浪微博等）舆论话题和情感变化进行研究。在省域范围内以小时为时间粒度的多维度有效性论证尚有欠缺,且在舆情分析时未能区分用户群体差异。本文以台风“利奇马”为例,在浙江省域范围内,以新浪微博数据为研究对象,首先从词频分析、台风关注度时空变化以及特定灾害事件响应3个角度探讨了微博数据对台风灾情响应的有效性;其次采用隐含狄利克雷分布（Latent Dirichlet Allocation,LDA）主题模型技术挖掘微博文本主题信息,并根据Louvain算法对主题社团进行划分;然后开发了一种基于自定义情感词典的情感分析方法用于情感指数计算,与SnowNLP相比情感倾向性预测精度得到了提高;最后分析了台风期间官方和民众在新浪微博平台上的话题关注以及情感演变差异。结果表明：① 在省级范围内,微博数据能有效反映台风动态和灾害时空分布;② 台风事件微博文本的主题变化反映了灾情不同阶段舆论关注点的动态变化;③ 官方微博文本比民众微博文本具有更明确的主题社团结构;④ 台风事件相关微博文本中的消极情绪在台风登陆后显著增加,其中民众微博文本对台风灾害的情绪响应更及时,官方微博文本中的情感表达始终相对积极。  相似文献   

Historical space as narrative medium: on the configuration of spatial narratives of time at historical sites   总被引：1，自引：0，他引：1  

Maoz Azaryahu  Kenneth E. Foote 《GeoJournal》2008,73(3):179-194

This paper examines how narratives of history are organized spatially at historical sites and memorial spaces, especially in urban settings and in places invested with a sense of collective memory. Much recent research has focused on landscape, memory, and place and how relationships of political and social power influence the representation of historical events in public spaces. Although the meaning of such sites may be hotly contested for long periods of time, we focus here on narrative theory and the related, but unexplored, issue of how such historical stories are configured on the ground at actual historical sites. We identify a number of narrative strategies which are frequently used to configure historical stories in space. Declamatory strategies using markers presenting a snapshot of an event are common, but sequential and non-sequential linear strategies are also used, as are thematic strategies that cross-cut space and time to present complex historical stories at various spatial scales. Examples are drawn from a range of historical sites in North America, Europe and Israel.  相似文献
