Abstract

Recent hazard literature frequently refers to sustainability and resilience as the guiding principles behind effective hazard planning. Certainly, structurally organizing communities to minimize effects of disasters and to recover quickly by restoring socio-economic vitality are laudable goals. However, while anticipating such outcomes is relatively easy from a theoretical standpoint, practical implementation of comprehensive plans is much more elusive. Indeed, relationships between community sustainability/resilience and hazards are complex involving many social, economic, political and physical factors. A conceptual framework for analysis of sustainability and resilience, then, is described based on three theoretical models, a mitigation model, a recovery model, and a structural-cognitive model. This framework is examined using data from Florida, USA, where local context, social and political activities, and economic concerns present difficulties in application. The question remains, therefore, to what extent can communities truly develop sustainable and resilient characteristics?  相似文献

A comprehensive review of online, official, and scientific literature was carried out in 2012–13 to develop a framework of disaster social media. This framework can be used to facilitate the creation of disaster social media tools, the formulation of disaster social media implementation processes, and the scientific study of disaster social media effects. Disaster social media users in the framework include communities, government, individuals, organisations, and media outlets. Fifteen distinct disaster social media uses were identified, ranging from preparing and receiving disaster preparedness information and warnings and signalling and detecting disasters prior to an event to (re)connecting community members following a disaster. The framework illustrates that a variety of entities may utilise and produce disaster social media content. Consequently, disaster social media use can be conceptualised as occurring at a number of levels, even within the same disaster. Suggestions are provided on how the proposed framework can inform future disaster social media development and research.  相似文献

洪涝灾害经济易损性模糊评价——以安徽沿长江地区为例   总被引:5,自引:1,他引:4  
张海玉  程先富  马武 《灾害学》2010,25(1):30-34
洪水灾害是洪水危险性对承灾体易损性综合作用的结果,由于降水量、人口密度、产值等因子在洪水易损性中的作用具有模糊性,因此运用模糊模型进行评价有一定意义。以安徽沿长江地区为例,在GIS和模糊数学法的支持下,建立了基于GIS的模糊综合评价模型,对洪水灾害经济易损性风险进行了评价与分析,将安徽沿长江地区洪涝的易损性程度划分为5个等级:高度易损性、较高度易损性、中度易损性、较低度易损性、低度易损性。研究结果表明:沿江洪水灾害易损性总体水平较高,特别是在马鞍山、芜湖市、铜陵市等经济发达、人口密集、耕地面积广阔的滨江下游平原区。这些地区应积极兴修水利,大力发展避洪产业。  相似文献

基于贝叶斯随机评价方法的小城镇灾害易损性分析   总被引:1,自引:0,他引:1  
为了准确评价小城镇灾害易损性所处的状态,进而为制定小城镇防灾减灾规划提供科学依据,提出了基于贝叶斯公式的小城镇灾害易损性随机评价方法。该方法通过计算小城镇灾害易损性单个指标属于某个评价级别的概率,由最大似然分类原则确定单个易损性指标的评价级别,进而采用最大加权概率原则推求其综合评价级别。通过实例计算分析,并与模糊评估方法、可拓物元评价方法进行比较验证,说明了该方法的可行性及其简单、实用的特点。  相似文献

Epidemiological procedures can be organised under disaster conditions by means of a simple surveillance system and with few personnel.
In the aftermath of the 4 February 1976 earthquake in Guatemala, an information system was organized by which the requisite information for decision-making was obtained with adequate speed and promptness.
The initial epidemiologic informution was based on reports collected during the early days on symptoms observed at hospitals and health centers and in localities and villages in the stricken area.
At a second, post-emergency stage a more elaborate surveillance system was instituted to provide guidance in the investigntwn of outbreaks, evaluate the health activities and establish basic criteria for preventive and control measures.  相似文献

China’s counterpart assistance policy is of vital importance in providing guidance for emergency management and post-disaster reconstruction. However, the amount of assistance that partner provinces should provide as well as the criteria that partners should abide by in offering counterpart assistance remain a main challenge. The goal of this research is to fill this gap by proposing a new framework consisting of an interregional input–output (IRIO) model and a resilience index. Subsequently, the indirect economic loss is obtained by utilizing the index system of provincial economic resilience assessments, with measures of indirect economic loss developed from the IRIO. Furthermore, to examine the internal validity and systematic error, the reliability of the adopted models, the calculation methods, and the index systems are investigated. To assess the external validity of the proposed measures and resilience index of the framework, data from the 2008 Wenchuan Earthquake are applied for estimating parameter values of the framework, and a follow-up investigation was conducted for examining the fairness and enhanced effectiveness of the new counterpart assistance criteria. In summary, this paper attempts to present some new ideas about the analysis of economic motivations of mutual aid and the improvement of the counterpart assistance policy.  相似文献

In river basins that cross jurisdictional boundaries, water quality degradation has become a crucial problem and results in intensive competition among water users, especially in developing countries. Under this situation, implementing water quality management and control across jurisdictional boundaries can strengthen watershed pollution controls, and prevent pollution from being passed on and promote active pollution control within the related jurisdictional regions. This study examined the limitations of the current trans-boundary water quality management system in China and reviewed the planning and implementation of two pilot integrated trans-boundary water management systems established in the Jiangsu and Zhejiang provinces. Based on our findings, we proposed a new policy framework for trans-boundary water quality management. As a first step toward integrated watershed management in China, this policy framework can help assess the actual water pollution status of various regions and serve as a basis for an integrated watershed management system. The framework can be easily applied in other countries with trans-boundary water pollution issues, particularly in the context of developing countries.  相似文献
