Citizen participation in disaster recovery projects and programmes in rural communities: a comparison of the Haiti earthquake and Hurricane Katrina

This study investigates predictors of local participation in recovery projects and programmes following Hurricane Katrina in the United States in 2005 and the earthquake in Haiti in 2010. Using two sets of survey data, it examines whether disaster impacts and social capital (social trust and civic engagement) are associated with disaster recovery participation and compares predictors of such engagement in the two locations. Multivariate logistic regression results reveal that physical injuries, limited community mobility, and government trust increase recovery participation in Haiti (n=278), whereas emotional distress and homeownership decrease it. On the Gulf Coast of the US (n=259), physical injuries and higher civic engagement augment recovery participation, while homeownership and age reduce it. The confounding factors of national contexts and post‐disaster time frames might explain the differences in the results. The discussion addresses the relation between country‐specific vulnerability and recovery participation and suggests implications for policy and practice to improve local citizens’ capabilities to participate in sustainable recovery processes.     

农村家庭认知与响应地震灾害的特点及其家庭际差异——以2007年云南宁洱6.4级地震灾区为例

以2007年云南宁洱6.4级地震灾区为例,通过现场访谈和问卷调查,分析了该地区农村家庭认知与响应地震灾害的特点及其家庭际的差异性。结果表明:当地农村家庭认知与响应地震灾害的水平尚不理想,综合防震减灾能力较弱;家庭对地震灾害知识和防震减灾技能的掌握程度,显著地影响着其在震时及震后的响应行为和态度,其中防震减灾技能的影响更显著;经济收入和教育背景不同的家庭,其地震灾害的认知水平和响应能力也呈现出明显的差异性,其中受教育程度的影响更明显,且可能是最根本的影响因素;家庭人口总数与家庭地震灾害认知与响应的综合能力呈显著的负相关关系,但这种影响也叠加了家庭经济文化因素的影响;对研究区而言,加强防震减灾实用技能和震时如何有效应对地震影响方面的教育,具有更重要的现实意义。     

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.     

Estimating the mitigation effect of Tokai earthquake measures on housing damage: a counterfactual approach

This paper evaluates the mitigation effect of Tokai earthquake measures on housing damage using a counterfactual approach. It focuses on those measures that stimulate ex‐ante investment in disaster prevention in the supposedly affected area, including earthquake‐proof retrofitting and improved housing construction; the effect of the measures on housing losses is estimated monetarily. The study compares factual disaster damage computed using a real distribution of houses with counterfactual damage to a hypothetical housing distribution that would occur if the measures were not implemented. The key findings are: (i) the disaster mitigation effects of Tokai earthquake measures on housing amount to approximately JPY 18 billion (USD 0.18 billion) for Yamanashi Prefecture and JPY 0.26 trillion (USD 2.6 billion) for Shizuoka Prefecture, which would be at the centre of the event; (ii) a before–after comparison biases estimates of the mitigation effect; and (iii) statistically, the measures do not mitigate the housing damage predicted for an earthquake in Tokai.     

山区公路强震灾害链影响与控制——以映卧公路为例

地震可以引发多种灾害链,尤其是强震。震区环境不同,引发的灾害链也不同。汶川特大地震发生后,映秀至卧龙公路两旁次生地质灾害尤为严重,先后多次中断震中交通生命线,严重影响公路的安全运行和灾后重建。由于山区公路环境具有特殊性,通过对震后映秀至卧龙公路边坡现场调查资料分析,山区公路强震灾害链主要可以分为公路自身系统及其灾害链和公路社会系统及其灾害链,并详细阐述了它们的形成过程和对山区公路环境的深刻影响。在此基础上,针对不同的链式影响提出了不同的灾害防治措施,以求达到断链的目的,将损失最小化。同时也为将来发生强震后山区公路的抢通与恢复重建提供一定的参考。     

The growing role of web‐based geospatial technology in disaster response and support

This paper examines changes in disaster response and relief efforts and recent web‐based geospatial technological developments through an evaluation of the experiences of the Center for Geographic Analysis, Harvard University, of the Sichuan (2008) and Haiti (2010) earthquake responses. This paper outlines how conventional GIS (geographic information systems) disaster responses by governmental agencies and relief response organisations and the means for geospatial data‐sharing have been transformed into a more dynamic, more transparent, and decentralised form with a wide participation. It begins by reviewing briefly at historical changes in the employment of geospatial technologies in major devastating disasters, including the Sichuan and Haiti earthquakes (case studies for our geospatial portal project). It goes on to assess changes in the available dataset type and in geospatial disaster responders, as well as the impact of geospatial technological changes on disaster relief effort. Finally, the paper discusses lessons learned from recent responses and offers some thoughts for future development.     

Emotional,physical, and social needs among 0–5‐year‐old children displaced by the 2010 Chilean earthquake: associated characteristics and exposures

An 8.8‐magnitude earthquake occurred off the coast of Chile on 27 February 2010, displacing nearly 2,000 children aged less than five years to emergency housing camps. Nine months later, this study assessed the needs of 140 displaced 0–5‐year‐old children in six domains: caregiver stability and protection; health; housing; nutrition; psychosocial situation; and stimulation. Multivariate regression was applied to examine the degree to which emotional, physical, and social needs were associated with baseline characteristics and exposure to the earthquake, to stressful events, and to ongoing risks in the proximal post‐earthquake context. In each domain, 20 per cent or fewer children had unmet needs. Of all children in the sample, 20 per cent had unmet needs in multiple domains. Children's emotional, physical, and social needs were associated with ongoing exposures amenable to intervention, more than with baseline characteristics or epicentre proximity. Relief efforts should address multiple interrelated domains of child well‐being and ongoing risks in post‐disaster settings.     

Behavioural,emotional, and cognitive responses in European disasters: results of survivor interviews

In the European multi‐centre study BeSeCu (Behaviour, Security, Culture), interviews were conducted in seven countries to explore survivors’ emotional, behavioural, and cognitive responses during disasters. Interviews, either in groups or one‐to‐one, were convened according to type of event: collapse of a building; earthquake; fire; flood; and terror attack. The content analysis of interviews resulted in a theoretical framework, describing the course of the events, behavioural responses, and the emotional and cognitive processing of survivors. While the environmental cues and the ability to recognise what was happening varied in different disasters, survivors’ responses tended to be more universal across events, and most often were adaptive and non‐selfish. Several peri‐traumatic factors related to current levels of post‐traumatic stress were identified, while memory quantity did not differ as a function of event type or post‐traumatic stress. Time since the event had a minor effect on recall. Based on the findings, several suggestions for emergency training are made.     

Temporary site selection and decision‐making methods: a case study of Tehran,Iran

Decisions on selecting an appropriate site for temporary shelter used to be taken in a limited amount of time after a disaster. The need for a systematic method in this area inspired the MADM (multi‐attribute decision making) for complex disaster management decisions. This research proposes a model for appropriate and systematic site selection for temporary shelters, before an earthquake, using a geographical information system and MADM based on an earthquake damage assessment. After the effective criteria for site selection of temporary shelters are determined, the geographical layers of these criteria are prepared for Municipal District No.1 of Greater Tehran, the capital of Iran. Given these attributes and the required shelter area (415–610 hectares), 14 zones are proposed initially. Various MADM methods are used for the final selection. The mean of the aggregated ranking results are determined, and 10 of the 14 initial zones are ranked.     

The feasibility of concentrated rural settlement in a context of post‐disaster reconstruction: a study of China

There is growing appreciation of the use of concentrated rural settlement as an effective means of implementing infrastructure projects and helping to achieve sustainable development in rural areas. This occurs in China through the exchange of rural residential land for urban construction. However, this policy has not been effective under normal circumstances (called development‐driven conditions) as frequently farmers are reluctant to accept such an exchange. By contrast, in a time of disaster, such as after the 2008 earthquake in Sichuan Province, China, rural victims have accepted this policy of rural residential land exchange. Employing game theory, this paper identifies the reasons for the different outcomes and it contends that the implementation of concentrated rural settlement practice under disaster‐induced conditions is more effective than its introduction under development‐driven conditions. The results of the analysis indicate that, in China, concentrated rural settlement is feasible in a context of post‐disaster reconstruction.     

Stressful but rewarding: Norwegian personnel mobilised for the 2004 tsunami disaster

Adequate responses to disasters and emergency situations rely, among other factors, on coping abilities in disaster workers and emergency personnel. In this study, different aspects of disaster-related stressors and training/experience were investigated in Norwegian personnel (n = 581) mobilised for the 2004 tsunami disaster. The level of stress reactions, measured nine to ten months after the tsunami, was relatively low in this sample, indicating that the personnel coped well with the challenges of the disaster. The level of intrusive memories was higher in disaster-area personnel (n = 335) than in home-base personnel (n = 246). Stress reactions were significantly associated with witnessing experiences (disaster-area group) and with having to reject victims in need of help (both groups). Specific preparation for the mission was associated with a lower level of stress reactions in disaster-area personnel. Such factors may be considered in training and preparation programmes for disaster workers.     

日美地震灾害紧急对应对中国灾害应急体制建立的启示

通过对美国1994年洛杉矶北岭地震反1995年日本阪神大地震时日美政府的地震灾害紧急应对过程,尤其是地震后的24小时内政府的初期对应,分析了日美地震灾害应急体制的特征,并就如何建立和完善中国灾害应急体系做了探讨。日美政府之所以在大地震发生时能有效地进行了紧急应对,在于健全的灾害应急体制。中国正处于经济和社会高度发展时期,面对各种各样的灾害和事故,要真正将灾害的损失降低到最低程度,必须尽快建立和健全以灾害应急规划体系、防灾情报系统、应急救灾指挥系统和专业化灾害援助队伍体系等为主的灾害应急管理体制。

Disaster resilience and population ageing: the 1995 Kobe and 2004 Chuetsu earthquakes in Japan

This paper provides a framework for evaluating the effects of population ageing on disaster resilience. In so doing, it focuses on the 1995 Kobe and 2004 Chuetsu earthquakes, two major disasters that affected Japan before the 2011 Great East Japan earthquake. It analyses regional population recovery on the basis of pre‐disaster and post‐recovery demographic characteristics using defined transition patterns of population ageing. The evaluation framework demonstrates that various recovery measures make different contributions to disaster resilience for each transition pattern of population ageing. With reference to regional population ageing, the framework allows for a prediction of disaster resilience, facilitating place vulnerability assessments and potentially informing policy‐making strategies for Japan and other countries with ageing populations.     

The barriers to environmental sustainability in post‐disaster settings: a case study of transitional shelter implementation in Haiti

Disaster recovery operations that do not account for environmental sustainability (ES) risk exacerbating the impact of the disaster and hindering long‐term recovery efforts. Yet aid agencies do not always consider ES. This research is a case study of the recovery that followed the 2010 earthquake in Haiti. Using timber and concrete procurement as proxies for broader post‐disaster operations, research examined perceptions of ES as well as attempts at and barriers to incorporating it into programming. Identified barriers can be grouped into two categories: (1) prioritisations and perceptions within the disaster response sector that resulted in limited enthusiasm for incorporating ES into programming, and (2) structural and organisational barriers within the disaster response framework that impeded ES attempts and served as a further disincentive to incorporating ES into programming. As a result of those barriers, incorporation of ES was sporadic and inconsistent and often depended on the capacity and motivation of specific implementers.     

Digital disparities and vulnerability: mobile phone use,information behaviour,and disaster preparedness in Southeast Asia

This paper proposes an ecological view to investigate how disparities in mobile technology use reflect vulnerabilities in communities vis‐à‐vis disaster preparedness. Data (n=1,603) were collected through a multi‐country survey conducted equally in rural and urban areas of Indonesia, Myanmar, Philippines, and Vietnam, where mobile technology has become a dominant and ubiquitous communication and information medium. The findings show that smartphone users' routinised use of mobile technology and their risk perception are significantly associated with disaster preparedness behaviour indirectly through disaster‐related information sharing. In addition to disaster‐specific social support, smartphone users' disaster‐related information repertoires are another strong influencing factor. In contrast, non‐smartphone users are likely to rely solely on receipt of disaster‐specific social support as the motivator of disaster preparedness. The results also reveal demographic and rural–urban differences in disaster information behaviour and preparedness. Given the increasing shift from basic mobile phone models to smartphones, the theoretical and policy‐oriented implications of digital disparities and vulnerability are discussed.     

Mental health and media links based on five essential elements to promote psychosocial support for victims: the case of the earthquake in Chile in 2010

This paper reviews the role of news with respect to the mental health of a population exposed to a disaster. It is based on the five essential elements of psychosocial care presented by Stevan E. Hobfoll et al. (2007) that can be introduced after a potentially traumatic event: promoting a sense of safety, calming, self and collective efficacy, connectedness, and hope. This study developed a method to relate these elements to television coverage and applied it to the stories (n=1,169) aired by the main networks in Chile in the 72 hours after an 8.8 magnitude earthquake struck on 27 February 2010. Of the five elements, promoting a sense of safety occurred most often (82.72 per cent), whereas the others were barely present (less than 10 per cent). The study argues that these elements can increase the possibility of framing the news, given that the audience watching can also be affected by a disaster.     

The time process of post‐earthquake recovery: the Yao'an earthquake in China

Post‐disaster recovery is a constantly changing and developing process. The authors conducted three real‐name follow‐up surveys at 1, 12 and 18 months after the Yao'an earthquake, which had a surface wave magnitude of 6.0. They also calculated recovery ratios at different times and drew post‐earthquake domestic life recovery curves. Based on the recovery curves, the time trajectory of domestic life recovery takes on an approximate S‐type development and change process. The recovery time process of domestic life can be divided into four periods: emergency period (weeks 0–2(5)), early recovery period (weeks 2(5)–24), rapid recovery period (weeks 24–34) and late recovery period (weeks 34–60(80)).
