Vulnerability of community businesses to environmental disasters

Business plays important roles in community functioning. ² However, disaster research has been disproportionately focused on units of analysis such as families, households and government agencies. This paper synthesises the major findings within the business development research field and the disaster research field. It constructs a framework for evaluating business vulnerability to natural disasters. Our theoretical integration of the research conducted to date addresses five major issues. First, it defines the ways in which businesses are subject to the impacts of natural disasters. Second, it identifies the factors that determine the magnitude of business impacts after a disaster. Third, it identifies how and when businesses return to their pre-disaster level in the disaster stricken community. Fourth, it describes measures that can be taken by individual firms and community planners to reduce the impacts of environmental disasters. Fifth, it identifies needs for public policy and future research to reduce business vulnerability to environmental disasters.

Natural disasters: a framework for research and teaching

Natural disasters are defined in this paper by relating the impact of extreme geophysical events to patterns of human vulnerability. Hazard perception is shown to be a factor that limits the mitigation of risk. The historical development of disaster studies is traced and five different schools of thought are identified. The current International Decade for Natural Disaster Reduction (IDNDR) is evaluated critically with regard to its potential for unifying the disparate strands of knowledge and its scope as a vehicle for education.
A pedagogical framework for disaster studies is presented. Time and space provide valuable unifying factors, while the subject matter can be differentiated according to the continua and dichotomies that it presents. In disaster studies as in other branches of higher education, an ecocentric approach is preferable to a technocentric one, as many of the poorer nations of the world, which are most afflicted by natural catastrophe, will have to rely for mitigation on maintaining their ecological sustainability, instead of depending on sophisticated technology. Valuable insights into the impact of environmental extremes on mankind are gained from the study of disasters as human ecology.     

The creation of vulnerability to natural disaster: Case studies from the Dominican Republic*

This paper argues that natural disasters are not a category of events which can be separated from the broader Issues of development, since economic change can create vulnerability to natural disaster. The analysis of case studies from the Dominican Republic shows how the development of large scale commercialized agricultural production has created such vulnerability by reducing or restricting the resource base of certain sectors of the population. It b suggested that the vulnerable state of a population should be considered as much a cause of natural disaster as the extreme physical phenomena Involved. Therefore there Is a need both for a broader framework for analysis of disasters and for strategies to reduce such vulnerability to be an Integral part of long term development planning.

我国农业水旱灾害的时间分布及重灾年景趋势预测

分析了我国 1970～ 1999年农业水旱灾害的时间分布特征。分析结果表明 :在研究时段内 ,我国农业自然灾害总体上呈增长态势。该时段可划分为两个明显的阶段 :80年代中期以前 ,总灾、水灾及旱灾对农业生产的危害较轻 ;80年代中期之后 ,呈现出影响范围广、损失增大的趋势 ,重灾年份明显增加。旱灾和水灾是威胁我国农业生产最为严重的自然灾害 ,尤以旱灾为甚。我国农业遭受旱灾威胁的范围多年基本不变 ,而旱灾受灾率波动明显 ,成灾率逐年增长 ,这与近几年农田水利设施建设缓慢、灌溉能力降低有关 ;水灾受灾率和成灾率具有特别显著的同步特点 ,表明水灾致灾能力强 ,一旦发生 ,极易成灾 ,水灾危害加剧与防洪、抗洪能力低下及生态环境恶化有关。各灾种的受灾率和成灾率呈正相关关系 ,表明我国农业生产系统的抗灾能力总体上较弱。　　本文还用灰色系统理论的建模方法 ,建立了农业总受灾率 -总成灾率、水灾受灾率 -成灾率、旱灾受灾率 -成灾率的重灾年景灰色灾变GM(1,1)预测模型 ,对未来 10年我国农业灾害趋势进行了预测分析。灰色预测结果表明 ,2 0 10年之前 ,除 2 0 0 3,2 0 0 6年水旱灾害危害较小外 ,其它年份均为灾情严重年份 ,其受灾率和成灾率均高于近 30年的平均水平。其中 ,2 0 0 4 ,2 0 0 7年将为水灾重     

自然灾害强度的评估方法及应用——基于综合灾情指数的研究

自然灾害造成的损失通常表现在多个方面,为了客观、全面地评估自然灾害,需要综合考虑多种灾情因素,最终才能得到灾害的总体评估结果。综合灾情指数(SDI)是对一系列灾情评价因子进行归一化、加权求和,这样得到的定量化的灾害评估指数,能够综合反映灾情信息。阐述了具有通用性的综合灾情指数,并设计开发了综合灾情指数工具,该工具包括评价因子、设置权重、规范化灾情指数和综合灾情指数4个模块。以汶川地震为例,利用综合灾情指数工具,对地震重灾区的灾害强度进行了综合评估。通过分析评估结果,综合灾情指数的分布真实地反映了受灾的严重程度,显示出该工具具有较好的实用性和有效性。

Judgement days: moral attitudes in the wake of local disasters

The deaths and destruction stemming from a disaster are traumatic enough to implicate victims' beliefs not only about disasters themselves but also about other social and political concerns. In particular, disasters are associated with the scapegoating of out‐groups, suggesting that even deep‐rooted moral concerns may shift, at least temporarily, after disasters. This study uses exposure to local natural disaster fatalities to examine moral judgements regarding gays¹ in United States surveys from 1984–98. Survey respondents whose county has suffered a disaster feel appreciably more negatively towards gays, even though most of the disasters in this data set are relatively small and local. The increased antipathy towards gays dissipates within months, and is most marked among those who had, before the disaster, considered themselves more religious. These results raise the possibility that some groups, especially those already marginalised by society, may suffer in a backlash in the wake of a natural disaster.     

Making a technological choice for disaster management and poverty alleviation in India

The right mix of policy, institutional arrangements and use of technology provides the framework for a country's approach to disaster mitigation. Worldwide, there has been a shift away from a strictly 'top-down' approach relying on government alone, to a combination of 'top-down' and 'bottom-up' approaches. The aim is to enhance the indigenous coping mechanisms of vulnerable communities; draw on their cooperative spirit and energy; and empower them through appropriate information and contextual knowledge to mitigate natural disasters. In light of this, the paper examines India's use of space technology in its disaster management efforts. Poverty alleviation and disaster management are almost inseparable in many parts of the country, as vulnerability to natural disasters is closely aligned with poverty. Addressing these issues together requires integrated knowledge systems. The paper examines how knowledge inputs from space technology have strengthened the national resolve to combat natural disasters in conjunction with alleviating rural poverty.     

Is the environment becoming more hazardous?—A global survey 1947 to 1980

This paper examines the assertion that natural disasters are increasingly destructive using evidence from disaster reports during the period 1947–1980. The criteria for judging the impact of a given natural disaster are chiefly loss of life and the extent of the geographical area affected. In spite of uneveness and bias in the reporting of sudden impact disasters the conclusions are that both the frequency of disasters and number of people killed are increasing. Further research into the social consequences of disasters and the need for disaster preparedness training programmes are recommended.

A proposed framework of key activities and processes in the preparedness and recovery phases of disaster management

This paper proposes an empirically grounded framework for examining the preparedness and recovery phases of disaster management activities and processes pertaining to predictable disasters within a developed country. The two‐stage framework provides a single model composed of important preparedness and recovery initiatives, as well as activities and processes derived from empirical data collected for case studies from Australia: the ‘Black Saturday’ bushfires in the state of Victoria in February 2009; and Cyclone Larry in March 2006. The framework enables a variety of analyses, including the generation of insights into disaster management preparedness and recovery in the context of events in wealthy developed countries. The paper combines two empirical examples, a series of bushfires and a severe tropical cyclone, to enhance understanding of, and to contribute to better, disaster preparedness and recovery in the future. The paper contributes to the growing literature on disasters, preparedness, recovery and associated logistics, and other issues.     

基于核密度估计的清代中国自然灾害时空分布特征

基于《清史·灾赈志》中的历史灾害信息,提取清代（1644-1911年）自然灾害共24 537县次,重建逐年灾害频次序列,以核密度估计法对5类主要灾害（水灾、旱灾、蝗灾、疫灾、冷害）的空间分布特征进行分析。结果表明:清代自然灾害频次序列没有明显的趋势性特征,而体现为阶段性波动,基于灾害频次30年滑动平均值可提取出4个峰值时段（1644-1673、1721-1750、1812-1841和1872-1901年）;相比于现代,清代灾害类型更加集中在农业灾害,最为多发的是水灾和旱灾,合计占总数的近80%,其次是蝗灾、疫灾和冷害;灾害最为多发的高风险区分布在黄淮海平原和长江三角洲,前者集中了水灾、旱灾、蝗灾的极端多发区,后者除了水旱多发,还是疫灾和冷害的极端多发区; 4个峰值时段的灾种类型组合和灾害多发区均有明显差异,时空变化受到致灾因子、暴露度和脆弱性因素的共同作用。上述工作有助于更好地认识历史灾害发生规律,对于当前及未来的防灾减灾工作具有重要参考价值。

Lessons for long-term social recovery following the 2004 tsunami: Community,livelihoods, tourism and housing

The Indian Ocean tsunami of 2004 galvanized world attention like no other natural disaster before. Unprecedented amounts of aid were given and a record number of international aid agencies were involved in relief and recovery operations. Major reviews of the response to the disaster have suggested that the immediate relief effort was better than expected. However, weaknesses in the longer term recovery work were identified within months of the disaster and yet the same weaknesses were being confirmed four and five years later. Even though many studies have been published on the tsunami disaster there are still many lessons to be learnt, particularly in relation to social recovery as distinct from the restoration of destroyed or damaged infrastructure. This paper presents an overview of the findings of a study that was conducted over a period of four years across five different tsunami-affected local areas of Sri Lanka and southern India. The study focused on lessons to be learnt in relation to rebuilding community, restoring livelihoods, recreating an appropriate tourism industry and providing relevant housing and planned settlements for disaster survivors. The paper argues that ‘build back better’ is possible, but only if ‘asset replacement’ strategies are replaced by integrated physical and social planning to address local needs in culturally appropriate ways. Much of what the authors advocate may seem to be little more than ‘common sense’ and many of our findings echo those of many other post-tsunami evaluations. Yet patient and well-integrated approaches to disaster recovery are all too rare in a world that is experiencing so many natural disasters. Because the 2004 tsunami evoked an unprecedented global response it is important to ensure that the lessons of the recovery effort are clearly learnt and this paper aims to convert research findings into a clear strategy for long-term social recovery.
