Barriers to the long‐term recovery of individuals with disabilities following a disaster

This study examines how pre‐existing disabling conditions influenced the recovery process of survivors of Hurricane Katrina. It focuses specifically on the barriers that hindered the recovery process in these individuals. Focus groups were convened in four Gulf Coast states with 31 individuals with disabilities who lived in or around New Orleans, Louisiana, prior to Hurricane Katrina in August 2005. Qualitative data were analysed using grounded theory methodology. Five themes emerged as the most significant barriers to recovery: housing; transportation; employment; physical and mental health; and accessing recovery services. While these barriers to recovery were probably common to most survivors of the disaster, the research results suggest that disability status enhanced the challenges that participants experienced in negotiating the recovery process and in acquiring resources that accommodated their disabilities. The findings indicate that, when disaster recovery services and resources did not accommodate the needs of individuals with disabilities, recovery was hindered. Recovery efforts should include building accessible infrastructure and services that will allow for participation by all.

Organisational resilience following the Darfield earthquake of 2010

This paper presents the preliminary findings of a study on the resilience and recovery of organisations following the Darfield earthquake in New Zealand on 4 September 2010. Sampling included organisations proximal and distal to the fault trace, organisations located within central business districts, and organisations from seven diverse industry sectors. The research captured information on the challenges to, the impacts on, and the reflections of the organisations in the first months of recovery. Organisations in central business districts and in the hospitality sector were most likely to close, while organisations that had perishable stock and livestock were more heavily reliant on critical services. Staff well‐being, cash flow, and customer loss were major concerns for organisations across all sectors. For all organisations, the most helpful factors in mitigating the effects of the earthquake were their relationship with staff members, the design and type of buildings, and critical service continuity or swift reinstatement of services.     

地震环境下不同重要性建筑的抗震设防水准

针对我国进行建筑物重要性分类时没有考虑地震环境影响的现实,采用地震危险性分析的方法将我国划分为地震危险性不同的3个区.同时,在采用调整设计基准期来标定建筑的重要性类别的基础上,利用地震动参数的危险性曲线,分析了不同重要性建筑在不同危险性特征分区内、不同设防概率水准(常遇、偶遇、罕遇地震)下的地震动参数(设防烈度、地震影响系数和地震地面运动加速度)的取值,最终证实调整结构的设计基准期并考虑地震环境的影响是标定结构的重要性从而调整设防等级的一种好方法.

The impact of the 2004 tsunami on coastal Thai communities: assessing adaptive capacity

The suddenness and scale of the 26 December 2004 tsunami and the challenges posed to affected communities highlighted the benefits of their members having a capacity to confront and adapt to the consequences of such a disaster. Research into adaptive capacity or resilience has been conducted almost exclusively with Western populations. This paper describes an exploratory study of the potential of a measure of collective efficacy developed for Western populations to predict the capacity of members of a collective society, Thai citizens affected by the 2004 tsunami, to confront effectively the recovery demands associated with this disaster. Following a demonstration that this measure could predict adaptive capacity, the role of religious affiliation, ethnicity and place of residence in sustaining collective efficacy is discussed. The implications of the findings for future research on, and intervention to develop, adaptive capacity among Thai citizens in particular and collectivist societies in general are discussed.     

School-based disaster risk reduction education in primary schools in Da Nang City,Central Vietnam

The concept of school-based disaster risk reduction (DRR) education has increasingly become popular as greater emphasis is placed on the role of schools in reducing risks and building the resilience of the education system. This paper discusses the variations in the implementation of DRR education among primary schools in different areas including urban, rural, mountainous, plain and coastal areas in Da Nang City, Central Vietnam. For rural schools, similarities in the implementation of DRR education are observed and schools in both rural plain and rural mountainous areas stress the provision of disaster-related training. In addition, improvement of school buildings and external relationship is important for the resilience of urban schools. Specifically, for schools in urban coastal areas, school location and structure are significant, while for schools in the urban plain lands, enhancement of collaboration with their community has the most potential to contribute to the resilience of a school. From that, this research proposes that leadership and prioritization are key factors in helping schools to manage internal and external resources to efficiently overcome challenges and effectively promote DRR education towards the enhancement of schools’ resilience.

Earthquake-strengthening policy for commercial buildings in small-town New Zealand

New Zealand introduced a seismic retrofitting policy in the wake of the catastrophic Canterbury earthquakes of 2010–11. The aim was to enforce seismic strengthening of earthquake-prone commercial buildings throughout the country. This study focuses on regional urban centres and the economic obstacles to strengthening their aging building stock. In investigating one town, Whanganui, we describe conditions, analyse cases, and identify incentives that apply equally to many other towns in New Zealand. We argue that incentives that suit high-growth, high-value major urban centres are a poor fit for the periphery. Around the world, many places need to upgrade their privately-owned building stock to protect it from disasters, while governments face similar challenges as they struggle to initiate the strengthening of commercial buildings. We analyse the current incentive schemes that aim to support the achievement of policy goals and suggest alternative incentive schemes that can be implemented to improve strengthening outcomes.     

基于有限元法的土坯民房地震响应分析研究

基于有限元法研究了土坯民房的地震响应特征,提出了实施土坯民房震害防治的对策性建议。地震动由结构底部向上传播时,低频部分被墙体吸收,水平加速度逐渐增大,揭示了低破坏性地震动损伤土坯民房屋盖系统、高破坏性地震动损坏土坯民房承重构件,进而导致整体结构损毁的动力机制。砖柱(木柱)承重土坯民房的地震响应大于墙体承重土坯民房,后者最大剪应力集中在中间开间的横墙和纵墙的连接处,最大主应力集中在中间开间的横墙上;前者最大剪应力集中在横墙和柱的连接处,最大主应力集中在中间开间的柱体上部。由于2种结构类型土坯民房的薄弱环节有所不同,地震时的致灾原因亦存在差异。

A multiple additive regression tree analysis of three exposure measures during Hurricane Katrina

This paper analyses structural and personal exposure to Hurricane Katrina. Structural exposure is measured by flood height and building damage; personal exposure is measured by the locations of 911 calls made during the response. Using these variables, this paper characterises the geography of exposure and also demonstrates the utility of a robust analytical approach in understanding health‐related challenges to disadvantaged populations during recovery. Analysis is conducted using a contemporary statistical approach, a multiple additive regression tree (MART), which displays considerable improvement over traditional regression analysis. By using MART, the percentage of improvement in R‐squares over standard multiple linear regression ranges from about 62 to more than 100 per cent. The most revealing finding is the modelled verification that African Americans experienced disproportionate exposure in both structural and personal contexts. Given the impact of exposure to health outcomes, this finding has implications for understanding the long‐term health challenges facing this population.     

福州市区地震灾害损失预测研究

基于福州市区地震危险性分析、地震地质灾害区划、建筑物和生命线易损性分析及防震减灾信息管理系统,本文介绍了在设定地震、历史地震、盲估地震和实时地震等4种不同地震参数输入下福州市区可能遭遇的地震灾害损失预测成果,提出了依据地面数据精度和设施类型划分的大城市地震灾害损失预测城市核心区、城乡结合部和乡村三个层次方案,并在此基础上确定了地震灾害损失的预测评估单元,即在城市核心区,地震灾害的损失评估单元可以是建筑物、居委会或区;在城乡结合部,地震灾害的损失评估以居委会或区为单元;在乡村地震灾害损失评估以乡镇和自然村为单元。根据系统模块,本文预测了8度地震烈度下福州市区地震灾害的总损失及其空间分布,其中全市区人员死亡约123人,重伤约654人,无家可归者约417100人,直接经济损失156.1亿元,并分析了地震灾害损失空间分布不均匀性的主要原因。     

The concept of resilience revisited

The intimate connections between disaster recovery by and the resilience of affected communities have become common features of disaster risk reduction programmes since the adoption of The Hyogo Framework for Action 2005-2015. Increasing attention is now paid to the capacity of disaster-affected communities to 'bounce back' or to recover with little or no external assistance following a disaster. This highlights the need for a change in the disaster risk reduction work culture, with stronger emphasis being put on resilience rather than just need or vulnerability. However, varied conceptualisations of resilience pose new philosophical challenges. Yet achieving a consensus on the concept remains a test for disaster research and scholarship. This paper reviews the concept in terms of definitional issues, the role of vulnerability in resilience discourse and its meaning, and the differences between vulnerability and resilience. It concludes with some of the more immediately apparent implications of resilience thinking for the way we view and prepare for disasters.     

Developing indicators to measure post‐disaster community recovery in the United States

Disaster recovery is a key capability of federal, state, and local government. To support this capability effectively practitioners need useful and validated metrics to document how well a community is recovering from a particular disaster. This study developed and categorised recovery indicators according to the Federal Emergency Management Agency (FEMA)'s Recovery Support Functions and Recovery Mission Area Core Capabilities through a literature review, an evaluation of the pre‐disaster recovery plans for 87 coastal jurisdictions, and a case study of two communities (New Hanover County, North Carolina, and the City of Hoboken, New Jersey). Metrics identified in the literature were validated through the recovery plan review and the case study. The research team also identified sources for both baseline and current status data. Based on these findings, a user‐friendly checklist for practitioners was established, which will be piloted with practice partners during a future disaster recovery initiative.     

New tools for emergency managers: an assessment of obstacles to use and implementation

This paper focuses on the role of the formal response community's use of social media and crowdsourcing for emergency managers (EMs) in disaster planning, response and recovery in the United States. In‐depth qualitative interviews with EMs on the Eastern seaboard at the local, state and federal level demonstrate that emergency management tools are in a state of transition—from formal, internally regulated tools for crisis response to an incorporation of new social media and crowdsourcing tools. The first set of findings provides insight into why many EMs are not using social media, and describes their concerns that result in fear, uncertainty and doubt. Second, this research demonstrates how internal functioning and staffing issues within these agencies present challenges. This research seeks to examine the dynamics of this transition and offer lessons for how to improve its outcomes—critical to millions of people across the United States.     

The self‐built ecovillage in L'Aquila,Italy: community resilience as a grassroots response to environmental shock

The paper applies the community resilience approach to the post‐disaster case of Pescomaggiore, an Italian village affected by the L'Aquila earthquake in 2009. A group of residents refused to accept the housing recovery solutions proposed by the government, opting for autonomous recovery. They developed a housing project in the form of a self‐built ecovillage, characterised by earthquake‐proof buildings made of straw and wood. The project is a paradigmatic example of a community‐based response to an external shock. It illustrates the concept of ‘community resilience’, which is widely explored in the scientific debate but still vaguely defined. Based on qualitative methodologies, the paper seeks to understand how the community resilience process can be enacted in alternative social practices such as ecovillages. The goal is to see under which conditions natural disasters can be considered windows of opportunity for sustainability.     

From disaster to development: a systematic review of community‐driven humanitarian logistics

A plethora of untapped resources exist within disaster‐affected communities that can be used to address relief and development concerns. A systematic review of the literature relating to community participation in humanitarian logistics activities revealed that communities are able to form ad hoc networks that have the ability to meet a wide range of disaster management needs. These structures, characterised as Collaborative Aid Networks (CANs), have demonstrated efficient logistical capabilities exclusive of humanitarian organisations. This study proposes that CANs, as a result of their unique characteristics, present alternatives to established humanitarian approaches to logistics, while also mitigating the challenges commonly faced by traditional humanitarian organisations. Furthermore, CANs offer a more holistic, long‐term approach to disaster management, owing to their impact on development through their involvement in humanitarian logistics. This research provides the foundation for further theoretical analysis of effective and efficient disaster management, and details opportunities for policy and practice.     

Towards a natural disaster intervention and recovery framework

Contemporary responses to facilitate long‐term recovery from large‐scale natural disasters juxtapose between those of humanitarian agencies and governments and those of the affected community. The extent to which these mechanisms articulate is crucial to the recovery propensity of the affected communities. This research examines such action by exploring the relationship between the scale of post‐disaster response interventions, the extent of community participation in them, and their impact on community recovery, using a community wealth capital framework. The investigation was applied to a study of the longer‐term community recovery of the island of Vilufushi, Republic of Maldives, which was almost completely destroyed by the Indian Ocean tsunami of 26 December 2004. Data were analysed through the employment of a pattern match technique and a holistic recovery network analysis. The research framework, informed by the case‐study results, other long‐term recovery evaluations, and existing resilience theory, is reconfigured as a testable roadmap for future post‐disaster interventions.
