The role of lifeline losses in business continuity in the case of Adapazari,Turkey

Despite the fact that one of the main reasons for business discontinuity after the shock of a natural disaster is lifeline outages, individual preparedness and recovery efforts have been given priority. This paper focuses on the significance of lifeline services for business continuity in order to highlight the necessity for collective action to achieve community recovery. Post-disaster research was conducted on a sample of business survivors in the town of Adapazari, which was severely affected by an earthquake in 1999. The study looked into the dependence of businesses on various infrastructure systems and the effects on those businesses of lifeline outages. The findings of the study address the need for community-level actions that are beyond the capability of any individual firm and which will ensure the continuity of business.     

Forgetting about hazard

Abstract

This paper examines long-term recovery outcomes of businesses impacted by major natural disasters. Data were collected via two large-scale mail surveys—one administered to Santa Cruz County, California businesses 8 years after the Loma Prieta earthquake and the other administered to businesses in South Dade County, Florida, 6 years after Hurricane Andrew. Based on the results of OLS regression models, we argue that long-term recovery experiences of businesses are affected by various factors, including the economic sector in which a business operates, its age and financial condition, and the scope of its primary market; direct and indirect disaster impacts, including physical damage, forced closure, and disruption of operations; and owner perceptions of the broader economic climate. Previous disaster experience, level of disaster preparedness, and use of external sources of aid were not found to significantly affect the long-term economic viability of businesses in the two study communities.     

城市化与现代社会中的水害演变：从日本经历看今日深圳

我国沿海经济开发区正进入城市化的活跃发展时期。发达国家的经历表明,城市化必将导致水灾害模式的变化,引出城市水灾损失持续上升的严重问题。日本从60年代中期开始研究城市型水灾害问题,随后其治水事业从方针、政策到对策均作了重大的调整,为社会经济的持续稳定发展创造了良好的条件。深圳市1993年两次暴雨洪涝成灾,损失惨重,其水情灾情均受到了该区域城市化的显著影响,说明我国城市型水灾害的研究亟待加强。本文从治水的角度将日本的城市化现象及其引起的水灾害特征变化与深圳市的实际情况进行了比较并得出若干有益的结论。     

The continued operation of businesses after an earthquake: a case study from Lushan County,China

This study performed a comparative analysis of changes in the operating status of initial surviving disaster‐stricken businesses and non‐disaster‐stricken businesses in Lushan County, China, after a devastating earthquake on 20 April 2013. It used a logistic regression model to explore the key factors associated with ‘post‐disaster continued business operation’ in the long term. Field data were collected from 1,078 businesses and questionnaire data from 263 small businesses between 2013 and 2017. The results indicate that a higher proportion of initial surviving disaster‐stricken businesses than non‐disaster‐stricken businesses managed to remain operational in each observation period. The continued operation of disaster‐stricken businesses after the earthquake was positively associated with the owner's age, previous disaster experience, pre‐disaster financial conditions, closure duration, and borrowing money from family or friends. A negative association was found with the size of the business. The findings serve as a vital reference for strategies to promote post‐disaster continued business operation.     

Disaster vulnerability of businesses in the 2001 Nisqually earthquake

Abstract

This paper examines the impacts of the February, 2001, Nisqually earthquake on businesses. Focusing on two hard-hit business districts in Seattle, the study investigates the extent of losses, patterns of disparities, and underlying loss factors. A conceptual framework is proposed of how business vulnerability dimensions contribute to disaster loss. Interviews were conducted with owners and managers of 107 businesses. Data were gathered on impacts, methods of finance, and disaster preparedness. Results showed that business losses were much greater than what standard statistical data would imply. Analysis found that a composite index of vulnerability—based on business sector, size, and building occupancy tenure—provides a very powerful predictor of business loss. Physical damage was a much weaker predictor of loss. Moreover, business recovery was influenced not only by characteristics of the business itself, but also by conditions in the neighborhood.     

Factors affecting post-disaster location choices of businesses: an analysis of the 1999 earthquake

Despite global policies advocating risk reduction and community level recovery, post-disaster implementations usually focus on households, but fail to focus on businesses in spatial terms. Due to the lack of appropriate policy and tools, businesses often make their own location choices as part of their recovery strategy. In view of this, this study aims to establish the factors affecting the location choices of businesses challenged by disasters in the absence of any specific spatial strategies designed for them. In order to determine these factors, empirical research was conducted in Adapazari, Turkey on 232 firms selected as a result of a stratified random sampling procedure. According to the analysis of the results, the most notable impacts on business location choices after a disaster shock are associated with occupancy status, education level, and extent of damage. In line with these findings, the impacts of business location choices are discussed to highlight the role of businesses in spatial decisions.     

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.

An ethical analysis of hydrometeorological prediction and decision making: The case of the 1997 Red River flood

Weather, climate, and flood predictions are incorporated into human decisions in a wide variety of situations, including decisions related to hazardous hydrometeorological events. This article examines ethical aspects of such predictions and decisions, focusing on the case of the 1997 Red River flood in Grand Forks, North Dakota and East Grand Forks, Minnesota (US). The analysis employs a formal ethical framework and analytical method derived from medical and business ethics. The results of the analysis highlight issues related to forecast generation, communication of forecast meaning and uncertainty, responsibility for the use of forecasts in decision making, and trade-offs between the desire for forecast certainty and the risk of missed events. Implications of the analysis for the broader arenas of weather, climate, and flood prediction and disaster management are also discussed.

淮河上游洪水灾害可公度信息系预测

可公度信息系是一种源于天文学的预测方法，其实质是寻求事物发生的经验关系。本文应用此法对淮河上游的洪水灾害进行了预测分析，结果表明淮河上游洪水灾害发生具有２ａ、４ａ、５ａ、７ａ、９ａ、１１ａ、１９ａ及７１ａ等多种周期，并在１９９７年、２０００年等年份的前后有可能发生大洪水。     

上海市水灾风险分析

利用1949-1990年上海市郊水灾历史灾情资料,分析其时空分布特征显示,自1949年以来,水灾受灾指数和相应粮食减产率呈阶段性下降,尤其自1977年水利控制片贯彻实施后,二者呈大幅度下降。各区县中,综合考虑水灾频次和受灾面积两个因素,得出南汇灾情最为严峻。最终,针对历史灾情资料缺乏、小样本数据使用传统统计模型进行风险分析精度不高的特点,基于信息扩散原理,利用正态信息扩散技术将单一的样本观测值变为一模糊集的模糊数学方法,对各区县受灾指数进行了风险分析,结果显示:南汇、浦东在受灾指数较低时,超越概率较高,即风险较高;崇明、金山在任一受灾指数下,风险都显示最高,受灾指数达0.8的超越概率为0.03345和0.01243,分别达到30年一遇和100年一遇。     

Lake Elsinore disaster: The slings and arrows of outrageous fortune

A case study of a flood which occurred at Lake Elsinore, California, February, 1980, focuses upon the assistance which the community received during both the flood and recovery periods. Relevant literature on disaster research is examined, including a model of disaster recovery, and the study places the events which occurred din Lake Elsinore within that recovery model. Implications for policy include the recommendation that decision-makers consider the pre-disaster growth of the community indecisions to support recovery assistance.     

Building community resilience: business preparedness lessons in the case of Adapazarı, Turkey

The lack of attention paid to businesses in disaster management systems from the standpoint of state policies hampers efforts to build community resilience. This paper examines, therefore, the extent of business preparedness for disasters. Empirical research was conducted in Adapazarı, Turkey, 13 years after the İzmit earthquake, which struck the northwest of the country on 17 August 1999, claiming the lives of some 17,000 people. For the study, 232 firms were selected to inquire about their preparedness before and after the event. It is hypothesised that business preparedness is influenced by the following set of variables: business size; business sector; business age; financial condition prior to the disaster; occupancy tenure; market range; education level; and previous disaster experience. In line with the findings of the research, a policy framework is constructed to rationalise the allocation of resources for building resilience at the aggregate level by facilitating business preparedness.     

Livelihoods,precarity, and disaster vulnerability: Nicaragua and Hurricane Mitch

How livelihoods determine vulnerability to disasters is a recent topic of inquiry. Few quantitative works have been produced to date. The empirical analysis that follows draws on household‐level data available for Nicaragua, preceding and following Hurricane Mitch, a devastating Category 5 storm that made landfall in Central America in October 1998, to examine differentials in disaster recovery outcomes vis‐à‐vis household livelihood profiles. Livelihoods are distinguished according to economic sector along with ownership of productive means, a central mechanism of vulnerability under sociological labour frameworks. The findings indicate uneven recovery outcomes in relation to livelihoods. During the year immediately following the event, agricultural wage earners and agricultural owner‐producers experienced marked losses owing to the disaster, whereas business owners saw an improvement in condition. Analysis of long‐term recovery reveals that households reliant on agricultural wage employment exhibit lagged recovery relative to other livelihood profiles. The findings are discussed with respect to the dynamic pressures posed by contemporary developmental processes.     

Impediments to recovery in New Orleans' Upper and Lower Ninth Ward: one year after Hurricane Katrina

In the aftermath of Hurricane Katrina, a rapid succession of plans put forward a host of recovery options for the Upper and Lower Ninth Ward in New Orleans. Much of the debate focused on catastrophic damage to residential structures and discussions of the capacity of low-income residents to repair their neighbourhoods. This article examines impediments to the current recovery process of the Upper and Lower Ninth Ward, reporting results of an October 2006 survey of 3,211 plots for structural damage, flood damage and post-storm recovery. By examining recovery one year after Hurricane Katrina, and by doing so in the light of flood and structural damage, it is possible to identify impediments to recovery that may disproportionately affect these neighbourhoods. This paper concludes with a discussion of how pre- and post-disaster inequalities have slowed recovery in the Lower Ninth Ward and of the implications this has for post-disaster recovery planning there and elsewhere.     

突出洪灾事件对新疆潜在气候转型的响应

从新疆近250年来的水文突出事件——洪灾的分析人手，探讨了其与新近提出的可能气候转型期降水变化的联系。结果表明，小冰期末以来新疆存在5个比较明显的重大洪灾时段。每一个时段基本上都对应着降水偏多时期，同时也对应着比较明显的气候转折期，前两次对应气温下降降水减少期，后三次对应气温升高降水增多期。20世纪80年代中期前后，洪灾灾情差异显著。20世纪80年代中期以来新，疆洪水及其灾害事件对气候(降水)变化响应较明显，表现出随着降水的增加，洪灾灾情加重、主要河流洪水洪峰流量突破历史极值的情况。这为气候转型观点的成立提供了一定的依据，并且还初步印证了前人有关气候转型初期自然灾害频发和洪水量级增大的论断。     

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

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。     

An integrated approach: managing resources for post-disaster reconstruction

A lack of resources for post-disaster housing reconstruction significantly limits the prospects for successful recovery. Following the earthquake in Wenchuan, China, in May 2008, housing reconstruction was not immune to resource shortages and price inflation. Difficulties in sourcing materials and labour considerably impeded recovery. This paper provides evidence of the resourcing bottlenecks inherent in the post-Wenchuan earthquake reconstruction process. Its aim is to present an integrated planning framework for managing resources for post-disaster housing rebuilding. The results are drawn from in-field surveys that highlight the areas where stakeholders need to concentrate effort, including revising legislation and policy, enhancing capacity for rebuilding in the construction industry, strengthening the transportation network, restructuring market mechanisms, and incorporating environmental considerations into overall planning. Although the case study presented here is country-specific, it is hoped that the findings provide a basis for future research to identify resourcing constraints and solutions in other disaster contexts.
