Disasters and environmental degradation create serious problems all around the world. They are inherently linked, but little attention is paid to their interaction, particularly at local levels. The degree of integration of disaster management and risk analysis with environmental management programs in relation to human vulnerability has been examined in Thua Thien Hue Province, Central Viet Nam. Unsustainable agricultural practices, and inappropriate development programs have contributed substantially to the increase of disaster risks. On the other hand, disasters damage natural resources and reduce environmental quality, indirectly contributing to increasing poverty which in turn, adds to the vulnerability of both natural and human systems, so further increasing disaster losses. Notwithstanding, in Viet Nam, there is a big gap between disaster and environment management policies and programs. In order to bridge the gap, an integrated approach in which environment-disaster linkage, rural—urban linkage, and poverty are brought into focus as core aspects of disaster management.  相似文献

Increased attention has recently been given to the possible role of financial services in the management of natural disaster risk. Local communities have been at the forefront of developing innovative disaster risk finance strategies and implementing risk-oriented incentive programs. In view of increasing risks, including the impacts of climate change, such programs will become more important. This paper examines four models and some recent experiences in using financial services at the community level. The paper offers an overview of advantages and limitations of each model to manage disaster risk in communities. Examples include a federal government initiated scheme of social protection funds, a local government risk reduction scheme, an insurance product provided by a non-governmental organization, and a micro-insurance scheme. Finally, the paper offers some directions about specific ways that the public and private sectors, in collaboration with other partners can improve finance alternatives for disaster management at the community level. It appears that a range of follow-up studies and further dialogue is needed, in order to expand the knowledge on what types of risk finance models can help manage and reduce the financial impacts of natural disasters.  相似文献

为探索高危岗位矿工风险感知的影响因素,在文献研究和复杂适应系统理论分析基础上,从个体角度构建矿工风险感知影响因素的系统动力学模型。运用Vensim 软件模拟仿真各工作时间段中,矿工风险感知水平及各因素对其影响的动态演化过程。研究表明:工作初期,情绪稳定性水平对风险感知水平促进效果显著,工作倦怠的抑制作用较突出;在工作后期,自我效能感对风险感知水平的削弱影响显著,风险规避态度则发挥较大的促进作用;风险知识经验超出一定范围会对风险感知水平起到反作用;安全教育培训与安全监管对风险感知水平的促进作用相对稳定持久。因此,煤矿企业应根据各因素在工作时间段的不同作用,采取相应措施以提高矿工风险感知水平。  相似文献

Learning about Environments: The Significance of Primal Landscapes   总被引:2,自引:1,他引:1  
The way we learn about our environments—be they farms, forests, or tribal lands—has implications for the formulation of environmental policy. This article presents the findings of how residents learned about their environments in two rural case studies conducted in northern Queensland and relates these to the concept of “primal landscapes,” which is concerned with the interaction that occurs between children and the environments in which they mature. Rather than focusing specifically on built environments or natural environments, the article draws on an approach that conceptualizes environment as meaning-laden places in which we live and work, which integrate social, cultural, biological, physical, and economic dimensions. In drawing insights for environmental policy, the article draws attention to the timing of policy interventions, the significance of experiential environmental education, the potential to learn from place-based festivals, and the importance of learning from extreme events such as fires and floods.  相似文献

This article reports a study of the public perception of large wood in rivers and streams in the United States. Large wood is an element of freshwater aquatic ecosystems that has attracted much scientific interest in recent years because of its value in biological and geomorphological processes. At the heart of the issue is the nature of the relationship between scientific recognition of the ecological and geomorphological benefits of wood in rivers, management practices utilizing wood for river remediation progress, and public perceptions of in-channel wood. Surveys of students’ perceptions of riverscapes with and without large wood in the states of Colorado, Connecticut, Georgia, Illinois, Iowa, Missouri, Oregon, and Texas suggest that many individuals in the United States adhere to traditionally negative views of wood. Except for students in Oregon, most respondents considered photographs of riverscapes with wood to be less aesthetically pleasing and needing more improvement than rivers without wood. Analysis of reasons given for improvement needs suggest that Oregon students are concerned with improving channels without wood for fauna habitat, whereas respondents elsewhere focused on the need for cleaning wood-rich channels for flood risk management. These results underscore the importance of public education to increase awareness of the geomorphological and ecological significance of wood in stream systems. This awareness should foster more positive attitudes toward wood. An integrated program of research, education, and policy is advocated to bridge the gap between scientific knowledge and public perception for effective management and restoration of river systems with wood.  相似文献
