Attrition and housing improvements: A study of post-disaster housing after three years

This research is part of an effort to monitor houses built for victims of hurricane Fifi in 1975. After 3 years (1978) we interviewed the residents to determine the rate of continued occupancy and the amount of housing improvement and the correlates of both. We found that a significant number of small families, Protestants, and families that had not participated in the construction of the housing had moved. From what we could determine, moving was primarily related to seeking work and improving one's financial position.
Nearly 90% of the permanent occupants had improved their houses with either indigenous or manufactured materials. Non-improvement of houses was concentrated among families with few members. The largest number of unimproved houses was located in the project that sewed the poorest victims and contained the cheapest housing.

Disaster devastation of US communities: long-term demographic consequences

This paper describes demographic changes resulting from devastating natural disasters in which at least half of the community's structures suffered major damage or total destruction. Considering 92 US communities that suffered disasters (mainly from hurricanes, river flooding, and tornadoes) between 1992 and 2008, locations that were already experiencing declining populations before their disaster were most likely to experience large post-disaster population losses. Communities suffering severe flooding were most likely to lose over a third of their population. Population movement typically occurred regardless of whether the community formally relocated. Small communities were particularly at risk of losing population following destruction, particularly when they lacked schools. Communities with higher home vacancy rates before their devastation were significantly more likely to experience large population declines. Wealthier communities and those located nearer metropolitan cities were most likely to retain their populations following major destruction, yet overall pre-disaster home values and median incomes in the communities were well below national averages. Race and Hispanic population were not significantly related to post-disaster population change in the overall study.     

The impact of local elites on disaster preparedness planning: the location of flood shelters in northern bangladesh

Disaster relief and preparedness organisations are concerned with allocating scarce resources in unstable environments, such as those prone to flooding and river erosion. The need to understand the role of powerful elites in such disaster prone environments is illustrated through an analysis of the actual location decisions and biases involved in siting four flood shelters in four communities in northern Bangladesh. The previously unrecognised implications of the location biases for employment, shelter, access and the utilisation of the flood shelter by the powerless people in the target group demonstrate the need for disaster organisations to include an analysis of the local power structure in project preparation and appraisal.     

紧急救援中公共建筑的伦理学

灾害评估将房屋分成框架结构和混合结构、砖木结构和土坯结构来评定损失.防震减灾中,除了上述分类外,更重要的是要考虑到"房屋-人"是一种相互不可分割的系统工程.房屋不仅仅是由砖石和水泥组成的,它同时是有"情感"的:人对房屋好一点,房屋就会对主人有报答.不少农村医院、学校等公共建筑,由于设计标准低、施工中存在偷工减料的现象,已经存在着隐患,只是在建造初期没有暴露出来.有了地震这一外力,加剧了矛盾,由"小患"变成了"大害".应当"以人为本",建议新建的建筑物应在当地基本烈度的基础上提高1度进行设计;对危旧房屋的改造,也应按在当地基本烈度的基础上加1度进行加固.可以分两步走:第一步,先加强地震多发地区的公共建筑,大约在全国有百余个县;第二步,在全国推广.     

自然灾害灾后重建技术及实践的研究进展

灾后重建是在灾害体发生之时及发生之后,采取应急救援、灾害管理,以及灾后评估、救助、规划等一系列过程,是一个典型的系统工程,可划分为前期应急重建、中期恢复重建及后期发展重建3部分。以自然灾害为主要研究对象,在分析中外关于灾后重建文献的基础之上,归纳了灾后重建的系统特征,介绍了灾后重建技术和实践的研究进展。灾后重建技术包括灾害分类分级、应急救援、灾后评估、灾害管理和重建规划5个方面,灾后重建实践研究分为地震、飓风、洪水和海啸4个方面,并对中外的灾后重建研究发展进行了展望。     

Building disaster resilience using social messaging networks: the WeChat community in Houston,Texas, during Hurricane Harvey

Analyses of disaster resilience have focused increasingly on the role of social capital and online social networks in recovery. This study complements this field of work by investigating three key issues. First, it examines how a social messaging application, WeChat, helped individuals to access and to mobilise three types of social capital—bonding, bridging, and linking—during Hurricane Harvey, a Category 4 storm that made landfall in Louisiana and Texas in the United States in August 2017, resulting in significant flooding and loss of life. Second, it pinpoints and assesses quantitatively how individuals' WeChat group usage and social capital influenced their post-disaster well-being. Third, it demonstrates how a minority and immigrant community in Houston, Texas, overcame the disadvantages commonly observed in other disaster research through the utilisation of social media. The findings of this study should aid governmental and community efforts to foster resilience in the face of natural and human-induced hazards.     

Theorizing distributive justice and the practice of post-disaster housing recovery

This paper examines the implications of contemporary conceptions of distributive justice for post-disaster recovery programmes. The question asked in this paper is essentially theoretical: what does a concern with distributive justice entail when developing and evaluating post-disaster recovery programmes? Housing recovery programmes are employed to provide a contextual grounding for the discussion. We present a review of the disaster recovery literature and recent programmes of post-disaster housing recovery to map the ways in which distributive justice have been theorized, interpreted, debated and put into practice. We reflect on what different principles of distributive justice imply for post-disaster recovery programmes in terms of their impact on opportunities for individuals and communities to recover from disasters, and also on their realizing possibilities of advancing justice in the post-disaster society. The paper concludes by outlining a number of dimensions of a pluralist account of distributive justice. Using these dimensions and taking into account tensions within and between them, we attempt to offer a framework for reflecting on and assessing distributive arrangements of disaster recovery programmes.

Successes and failures in post-disaster resettlement

In this article I examine the problem of the resettlement of populations after disaster. After considering the complexity of the resettlement process in general and the reasons resettlement is often chosen by authorities following disaster, I discuss a theoretical perspective from development project resettlement which may have relevance for disaster research. This is followed by an examination of those factors in post-disaster resettlement projects which have proved important in affecting successful or unsuccessful outcomes. Site, layout, housing and popular input are presented as crucial issues in the determination of success or failure in post-disaster resettlement. Case material from Turkey, Iran and Peru is presented to illustrate how failure to attend to these issues produces unsuccessful resettlement villages. Case material from Turkey is used to illustrate how attention to these factors improves chances of success in resettlement. Material from cases of voluntary, spontaneous post-disaster resettlement in Guatemala is also presented to underscore the importance of popular participation for successful resettlement despite insufficiencies in design and material inputs. The article ends with a brief consideration of resistance to resettlement and alternative policies.     

中国农村地震灾害特点及减灾对策

致灾因子强度和承灾体的脆弱性共同决定了灾情的大小.中国农村乡镇发生地震的概率远远高于大中城市,西藏、新疆、云南、宁夏、青海、甘肃等西部农村乡镇是我国地震灾害最为严重的地区.地震灾害对农村乡镇造成的损失,主要是农村居民住房的破坏,约占总损失的80%以上;其它的20%损失中,又以农村水利工程的破坏损失为主.目前我国农村乡镇居民的住房仍以抗震性能较差的土木、砖木结构为主,开展农村住房地震保险、农村低息住房贷款并加强农村建房的监督管理,是降低农村地震风险、减轻农村地震灾害损失的主要对策.     

Ethnicity,income, and disaster preparedness in Deep South Texas,United States

This paper examines the influence of a series of demographic and socioeconomic factors on preparedness outcomes for a sample of residents of the Rio Grande Valley in the southernmost part of Texas, United States. Data were collected as part of the regional Pulse of the Valley Study, a general social survey of south Texas residents conducted by the Center for Survey Research at the University of Texas‐Rio Grande Valley. The purpose of this investigation is to understand better the effects of ethnicity and income on preparedness within a region of the US that suffers from widespread poverty and limited infrastructure and is prone to flooding and hurricanes. Taken together, the results suggest that while age, disaster experience, and income are associated with preparedness, the relationship between preparedness and ethnicity remains complex. Furthermore, policymakers should consider initiatives that address the socioeconomic and other issues that shape preparedness for a disaster.     

Long-term gendered consequences of permanent disabilities caused by the 2005 Pakistan earthquake

This study documents the long-term gendered impact of the 2005 Pakistan earthquake on women and men who were rendered paraplegic as a result of spinal cord injuries sustained during the disaster. Coping mechanisms are also mapped. The findings show that three years after the disaster, paraplegic women are socially, emotionally, and financially isolated. The small stipend they receive is a significant source of income, but it has also led to marital distrust, violence, and abuse. In contrast, men receive full social and emotional support. Their key concern is that the government is not providing them with opportunities to be economically productive. Contemporary discourse and post-disaster policies, while acknowledging the importance of incorporating a gender perspective in the immediate post-disaster period, have failed to acknowledge and address the longer-term gendered impact of disasters, in terms of the different types of impact and strategies adopted by women and men.     

Towards a Redefinition of Security in Central America: The Case of Natural Disasters

Over the past 25 years Central America has suffered a number of major disasters: the Managua Earthquake (1972), Hurricane Fifi (1974), the Guatemalan Earthquake (1976), the San Salvador Earthquake (1986) and Hurricane Joan (1988). These events are briefly described, with special reference to their political aspects and implications. Recognition of the political importance of disasters in Central America leads to a questioning of the traditional notion that security is essentially a matter of defending the state from outside aggression. It is suggested that the analysis of disasters should be part of the debate that is currently underway in international relations about redefining the concept of security in the post-Cold War world.     

Women's experiences across disasters: a study of two towns in Texas,United States

Gender, although gaining attention, remains under-researched in disaster risk reduction protocols and response and recovery efforts. This study examines women's experiences of two disasters in small towns in the United States, utilising qualitative interviews with residents of Granbury and West, Texas, during the first year of disaster recovery. Granbury was struck by an EF-4 tornado on 15 May 2013, whereas an explosion occurred at a local fertiliser facility in West on 17 April 2013. The paper explores how women's experiences of inter-gender power dynamics in decision-making, the prioritisation of childcare, and women's participation in the community affect their post-disaster recovery. Previous research highlights different forms of human response and recovery vis-à-vis ‘natural’ and technological disasters, with less attention paid to gender differences. The results point to the persistent, and similar, effect of gender stratification on women's experiences across different types of disasters in the US and the continued importance of gender-sensitive disaster policies and programmes.     

基于可变模糊聚类的城镇综合承灾能力评价研究

城镇灾害的多样性、频繁发生与其造成的各种损失和破坏的严重化趋势,已经对城镇经济社会发展构成重大威胁。城镇应对灾害的预测、防御、救助及灾后恢复的综合能力,直接决定了城镇可持续发展的基础和能力。建立了基于城镇社会、经济和环境属性功能的城镇综合承灾能力评价指标体系,运用可变模糊聚类方法,通过指标权重、相对隶属度与聚类中心之间的动态迭代,得到了更为合理的样本城镇的防灾、抗灾、救灾和灾后恢复能力相对比较结果。与已有研究相比,可变模糊聚类在综合评价问题上的数据处理和分析能力更客观和多样化。

韧性理论视角下贫困村灾后恢复重建与灾害风险管理刍议

韧性理论引入灾害风险管理领域,为世界防灾减灾实践提供了新理念,并在国内外韧性城市社区建设中得到广泛应用,但针对乡村地区,尤其是高脆弱性的贫困村韧性社区建设的研究还较为鲜见。该文以韧性理论为基础,结合乡村振兴战略规划,通过对贫困村社会生态系统特征的分析,探讨了新时期我国贫困村灾后恢复重建与灾害风险管理发展方向及特点。研究发现:贫困村不仅产业经济落后,而且还具有自然环境复杂、基础设建设滞后、社会公益设施匮乏、教育水平较低、自然灾害频发等特点。这类灾害多发区与贫困人口聚集区在空间上的叠加,成为我国社会生态系统高脆弱性地区,面临着严峻的防灾减灾与扶贫开发的双重挑战;基于韧性理论视角,通过构建贫困村适灾韧性系统,开展贫困村社区韧性综合评价,调整贫困村灾后恢复重建规划编制理念等,以推动贫困村灾后恢复重建的转型;在此基础上,结合贫困村社会生态系统特点,以建立健全贫困村灾害风险管理机制、探究提升贫困村适灾韧性社区建设的新途径、协同灾害管理与乡村振兴发展目标、开展灾区恢复重建动态监测与后效评价等政策举措为抓手,深化贫困村灾害风险管理实践,提升贫困地区可持续发展能力。     

基于国内外灾害经济研究与管理实践的启示

中外学者从不同视域对灾害经济与管理问题进行了研究,形成了一些有代表性的观点。各国政府在防灾减灾、灾后重建等方面也积累了大量的经验。这些观点和经验为我们深入研究灾害管理机制奠定了基础,结合汶川8.0级地震导致的惨重损失及灾后重建出现的问题,阐述了构建我国以人为本的灾害管理机制和可持续重建地震灾区的基本对策。     

Towards an earthquake-resilient world: from post-disaster reconstruction to pre-disaster prevention

ABSTRACT

Destructive earthquakes in urban or rural areas around the world have caused severe damage to local societies. Pre-disaster prevention and post-disaster reconstruction can significantly reduce the impact of earthquakes on communities. To explore the popular research topics and trends in this area, CiteSpace was used to develop a knowledge map visualization. It was found that the main research into earthquake disaster prevention and reconstruction has been focused on disaster risk reduction planning, disaster mitigation knowledge, participatory disaster governance, and community resilience building. In this Special Issue, there were six distinctive earthquake disaster research papers that covered scientific, social, and institutional aspects. It was concluded that to reduce the effects of earthquake disasters, an interdisciplinary research approach and systems thinking is needed. The investigation also revealed that there has been a paradigm shift from post-disaster reconstruction to pre-disaster prevention to build community and urban resilience.
