Abstract: The physical, economic, and sociocultural displacement of local peoples from protected areas generates intense discussion among scholars and policy makers. To foster greater precision and clarity in these discussions, we used a conceptual framework from the political economy literature to examine different forms of human displacement from protected areas. Using marine protected areas (MPAs) to ground our analysis, we characterized the 5 types of property rights that are reallocated (lost, secured, and gained) through the establishment of protected areas. All forms of MPA "displacement" involve reallocation of property rights, but the specific types and bundles of rights lost, secured, and gained dramatically shape the magnitude, extent, and equity of MPA impacts—positive and negative—on governance, economic well-being, health, education, social capital, and culture. The impacts of reallocating rights to MPA resources vary within and among social groups, inducing changes in society, in patterns of resource use, and in the environment. To create more environmentally sustainable and socially just conservation practice, a critical next step in conservation social science research is to document and explain variation in the social impacts of protected areas. 相似文献

输变电工程电磁场引起公众风险感受调查分析 总被引:2,自引:0,他引:2
为了解和掌握输变电工程运行产生电磁场引起公众风险感受的心理状态,以制定出合理的策略来缓解和降低这种恐慌情绪,采用社会心理学的调查研究方法,在开展对公众定性访谈的基础上,归纳总结获取的信息、设计问卷,以实现对更大范围的公众进行风险感受相关信息的调查与统计。数据分析表明,公众对电磁场原理及相关信息的不了解,是使得这一风险事件具有群体性特征,进而导致其蔓延和激化的主要原因,建议在制定宣传策略的同时,加强对输变电工程相关信息公平、公正、公开的管理,以营造和谐与信任的沟通氛围。 相似文献

秦岭自然保护区群的社会效益计量研究 总被引:4,自引:0,他引:4
秦岭自然保护区群在我国生物多样性保护方面发挥了重要作用,学术界一直缺乏其社会效益计量的研究.该研究在界定秦岭自然保护区群社会效益的概念及分析其内涵的基础上,综合运用专家咨询法及文献参考方法,初步建立了秦岭自然保护区群社会效益计量指标体系,包括:社会文明进步、人类健康和社会生产生活改善3种类型11项指标.利用市场价值法、等效替代法等方法,对秦岭自然保护区群保护生物多样性的过程中所产生的社会效益进行了计量及分析.结果表明:秦岭自然保护区群在保护生物多样性的同时,每年产生了相当可观的社会效益,总货币量约11.68亿元人民币,与周边区域密切相关的社会文明进步效益为1.68亿元;人类健康效益为1.62亿元;社会生产生活改善效益为8.37亿元.该研究的社会效益计量指标及计量方法可为秦岭自然保护区群基层工作人员及类似保护区社会效益计量及评价提供参考. 相似文献

在人本主义地理学框架下,对城市社会空间结构的分类研究成为必然。以流动人口空间结构为主题,总结了城市化一空间的二元分析框架。在此基础上重点构建了流动人口空间结构体系,对流动人口区位空间、行为空间和感应空间的涵义、特征、功能等进行解析。认为流动人口空间是在城市空间基底上叠加的具有流动人口特质的空间形态,是一种再造的空间。提出流动人口收入水平及行为活动的多少是影响流动人口空间关系的主要因素。 相似文献

通过对安全生产许可证进行"抽象"处理为安全生产权,然后对安全生产权再进行"物化"处理成安全生产票,最后通过安全生产票的发行、配售、回收、没收、转让、储存、追加等市场手段实现安全生产票在各个企业的分配;通过安全生产票与企业安全生产量的"强制"关联关系决定企业的产量和产值,并由此影响企业的利润,使得企业管理者关心和重视企业的安全生产.由此,使得企业安全生产工作落到实处,最终达到安全生产的目标. 相似文献

Sustainable development is one of the most important ideas, and goals of our time. It is defined as "development which meets the needs and aspirations of the current generation and develops safe and sound society for future generation". Achieving sustainable development thus involves a vigorous and urgent debate on different dimensions. The different dimensions of sustainability as a framework involve all issues such as science, technology, economic growth and development, health, education, finance investment and trade, politics, natural disasters, population growth and terrorism, etc. No single dimension is responsible to develop sustainable society. This article mainly described the integrated relationship among the three dimensions ofsustainability. 相似文献

ABSTRACTIn order to develop conceptual models that reflect the realities of networked communicative processes scholars must examine both the underlying network structure and the content of these ties. Using mixed methods, I apply a relational perspective to the role of digital technologies in transnational organizing, using activism against high-volume hydraulic fracturing as a case study. In-depth interviews are combined with social network analysis of hyper-linkages between organizations supporting a day of action calling for a ban on fracking, Global Frackdown. Analysis shows that activism against unconventional fossil fuels brings together very localized concerns about environmental risks associated with extractive industries with more abstract global concerns. I apply the concept of translocal to examine environmental organizations and movements. This conceptual shift focuses on the brokerage role of global-minded local groups in mediating global issues back to the hyper-local scale. While international NGOs play a coordinating role, local groups with a global worldview can connect transnational movements to the hyper-local scale by networking with groups that are too small to appear in a transnational network. 相似文献

A decision support tool aiming to facilitate discussion and transparency in land-use planning processes has been developed. It includes process steps initiating with an analysis of the current situation, identification of relevant actions and sustainability analysis steps. The sustainability was subdivided into human health and environment, resources, and social and economic impacts. The main difference between this risk analysis tool and others is the allowance of comparisons of present risks and consequences of measures early in the process. It also includes assessments from short- and long-term perspectives, such as taking into account climate change. It combines classic risk analysis with life-cycle assessment procedure. It has been developed and tested in co-operation with municipalities. The tests show that the tool is applicable and can be relevant in the planning process. It offers an iterative discussion framework that is systematic, condensed and yet a simplistic way of describing consequences. The criticism is that it is regarded as time demanding, but this can be managed by preparatory work. 相似文献
