ABSTRACTNorthern coastal regions are facing multiple challenges from accelerating global environmental and socioeconomic changes, such as ecosystem degradation, climate change, intensified resource extraction, land use change and declining populations. Based on interviews with 13 farmers, fishers and aquaculture employees from coastal Nordland, northern Norway, this study demonstrates how the local stakeholders’ perceptions of change and experiences of vulnerability are closely linked to their livelihood values and worldviews. What the informants consider a sustainable and meaningful way of coastal living does not coincide with national goals for sustainable, natural resource dependent development of the region. The article demonstrates the importance of attending to local values if policymakers and managers are to ensure successful local mobilisation, reduce vulnerability to ongoing and future processes of change, and ensure legitimacy and consistency in development goals of coastal zone management. Insights from this study are useful for local and regional decision makers with responsibility for natural resource policies and development efforts. 相似文献

为分析高速公路应对流量冲击和恶劣气象环境侵扰时的运行状态演变过程,基于韧性理论的系统解析,构建了考虑吸收能力、适应能力、恢复能力3个维度的韧性评估方法;设定重大节假日和恶劣天气2种侵扰场景,与常规场景进行对比分析,并选取滇西高原山区高速公路为实例进行验证。研究结果表明:恶劣天气降低了高速公路的总体韧性,韧性值较常规运行减少685%;重大节假日的流量冲击主要影响高速公路韧性的稳定性,其方差较常规运行增加92%;2种侵扰场景下的恢复能力波动均较大,而重大节假日时高速公路的吸收能力较强。 相似文献

为明晰辱虐管理、自我损耗和工作倦怠对安全绩效的作用机理,在文献研究和开放式访谈的基础上,建立四者关系的假设模型。采用辱虐管理量表、自我损耗量表、工作倦怠量表和安全绩效量表对389名员工进行调查,通过SPSS和AMOS进行相关分析和中介效应检验验证假设模型。结果表明,辱虐管理、自我损耗和工作倦怠两两之间均呈显著正相关,而辱虐管理、自我损耗和工作倦怠三者均与安全绩效呈显著负相关。辱虐管理不仅可以直接预测安全绩效,还可以通过3条路径间接影响安全绩效:通过自我损耗的独立中介作用;通过工作倦怠的独立中介作用;通过自我损耗和工作倦怠的链式中介作用。有效干预辱虐管理、自我损耗和工作倦怠,能提升安全绩效水平,减少人因失误。 相似文献

Prescribed burning is now a widely accepted bushfire hazard management strategy. While evidence points to reduced levels of public health harm compared to severe bushfire, smoke created by planned burns remains a community concern with need for evidence-based public health management. Findings are presented from an Australian study of community experiences of prescribed burns, associated smoke, and public health communications. We find that “place” influences how information is received and used for the management of the effects of planned burns; and that this is significant for human agency and community resilience. We provide recommendations for public health management. 相似文献

This paper examines the realism of the resilience ambition and process of the U.S. housing system, shedding light on its heterogeneity as well as the financialization currently acting as the driving force in real estate production. The resilience ambition leading to enhanced justice and egalitarianism is understood as the provision and maintenance of post-disaster housing for all within an institutionally diverse landscape of housing policy makers and implementers. Particular emphasis is given to the post-Katrina institutional transformations resulting from multifarious interactions between multilevel institutional structures and a diverse landscape of low-income housing policy implementers – referred as social resilience cells (SRCs) in this paper. The nature and level of these transformations determine the degree to which resilience in its heterogeneous form has been incubated in New Orleans. The paper concludes with a discussion on the macro conditions and bottom-linked governance structures under which all SRCs could be better bolstered in a post-financialization, radicalised neowelfare U.S., and which in turn create possibilities for materialising the resilience ambition. 相似文献

区域水灾恢复力及水灾风险管理研究——以湖南省洞庭湖区为例 总被引:5,自引:0,他引:5
近年来灾害恢复力研究在领域的拓展和定义的延伸等方面取得了较大的进步。灾害恢复力作为系统的一个有价值的属性,与风险、脆弱性和适应性一起成为当前灾害综合管理和减灾研究的重要内容。但目前灾害恢复力研究仍停留在理论和概念层面,鲜有深入的实际操作性强的工作开展。为进一步理解水灾恢复力的内涵和实质,为区域恢复力建设提供切实可行的方案,作者在原有对灾害恢复力研究进展进行综述的基础上,开展了以湖南省洞庭湖区为例的洪水高风险区水灾恢复力理论和实践的研究,提出了由自然维、经济维、组织维、社会维组成的四维区域水灾恢复力概念模型,然后细致分析了区域水灾恢复力利益主体的相互关系,提供了初步的区域水灾恢复力评估模型。最后在定性分析的基础上,对洞庭湖区区域水灾风险管理进行了探讨,提出了相应的管理对策和建议,旨在为政府的防灾减灾决策提供科学依据。 相似文献

/ Mechanized military maneuvers are an intensive form of disturbance to plant communities in large areas throughout the world. Tracking by heavy vehicles can cause direct mortality and indirectly affect plant communities through soil compaction and by altering competitive relationships. We assessed the long-term condition of structural attributes of open woodland, grassland, and shrubland communities at Fort Carson, Colorado, in relation to levels of disturbance and soil texture. Covariate analyses were used to help separate the directional forcings by the chronic disturbance from the regenerative capacities in order to assess the relative resistance and resilience of the communities and to determine whether the continual disturbance-recovery processes balanced under current levels of utilization. All three communities responded differently to disturbance. In open woodlands, altered understory/overstory relationships were suggested by increased grass, forb, shrub, and total vegetation cover and smaller decreases in shorter than taller woody species with increasing levels of disturbance. Grassland communities generally displayed greater responses to disturbance than other communities, but temporal dynamics were often similar, indicating relatively less resistance but greater resilience of this community. Weed and exotic species increased both temporally and in relation to levels of disturbance in all three community types. Temporal trends in community-level indices of dissimilarity and diversity also indicate that rates of disturbance were greater than rates of recovery. Few variables were related to within-community differences in soil texture. While total aerial cover was temporally stable, changes in species composition and in basal cover in grasslands and shrublands suggest increasing erosion potential. 相似文献

A systematic review of literature on community resilience measurement published between 2005 and 2014 revealed that the profound lack of clarity on risk and resilience is one of the main reasons why confusion about terms such as adaptive capacity, resilience, and vulnerability persists, despite the effort spared to operationalise these concepts. Resilience is measured in isolation in some cases, where a shock is perceived to arise external to the system of interest. Problematically, this contradicts the way in which the climate change and disaster communities perceive risk as manifesting itself endogenously as a function of exposure, hazard, and vulnerability. The common conceptualisation of resilience as predominantly positive is problematic as well when, in reality, many undesirable properties of a system are resilient. Consequently, this paper presents an integrative framework that highlights the interactions between risk drivers and coping, adaptive, and transformative capacities, providing an improved conceptual basis for resilience measurement. 相似文献
