Hull, a city in the East Riding of Yorkshire, United Kingdom, suffered severe flooding in June 2007, affecting some 8,600 households and most schools. Despite the potential for damage in such disasters, no studies of the effects of floods on teachers and schools in the UK appear to have been published previously. This study analysed the impacts of the floods on teachers in Hull in two stages: first through correspondence with Hull City Council and a mailed questionnaire to 91 head teachers of primary, secondary, and special schools; and second, through in‐depth interviews with head teachers from six flooded schools, representing different degrees of flood experience, and a questionnaire completed by eight teachers from the same schools. The findings reveal the importance and the complexity of the role of the school in the wider community in a time of crisis. The study highlights issues concerning preparedness for floods, support for schools, and flood protection for schools. 相似文献

This paper explores peoples' indigenous survival strategies and assesses variations in people's ability to cope with floods in two flood‐prone villages in Bangladesh. It reveals that people continuously battle against flood vulnerability in accordance with their level of exposure and abilities, with varied strategies employed at different geophysical locations. The paper reports that people in an area with low flooding and with better socioeconomic circumstances are more likely to cope with impacts compared to people in areas with high and sudden flooding. Similarly, households' ability to cope varies depending on people's socioeconomic conditions, such as education, income and occupation. Although floods in Bangladesh generate socioeconomic misery and cause damage to the environment, health and infrastructure, people's indigenous coping strategies have helped them to reduce significantly their vulnerability. Such flood‐mitigating strategies should be well recognised and emphasised further via proper dissemination of information through an early‐warning system and subsequently external assistance. 相似文献

防洪工程作为人类抵御洪灾的首选手段,为人们提供了保障,但人们对其风险认知还存在一定的偏差。本文从公众层面入手,在我国历史上洪灾最严重的两大流域—长江流域和黄河流域,分别选取岳阳沿洞庭湖区和开封沿黄河地区为研究区,调查公众对当地防洪工程的信赖状况和水灾风险认知情况,回收有效样本831份。据此分析影响防洪工程信赖的因素和工程信赖对公众风险认知的影响。研究发现,公众对防洪工程的信赖度较高,区域趋同性明显;公众对工程信赖的程度,因居住地与风险源的距离、性别、年龄和家庭劳动力结构的不同而存在差异;同时,对防洪工程的过于信赖,会降低公众对洪灾的恐惧心理和警惕性,并使得公众产生消极和积极并存的应对灾害的行为倾向。洪灾多发地区应建立大型洪灾、巨灾的风险防范和洪水保险机制,完善我国的再保险制度;政府在高风险区的分区域管理过程中,应以大局为重;构建"文化自觉"的科学防灾文化观,正确引导公众认识到工程措施能力的限度,扭转在工程信赖基础上的风险认知偏差。 相似文献

The Manawatu floods of 2004 have had significant, long-lasting social consequences. This paper draws on findings from a series of detailed surveys of 39 farm households directly affected by the floods and 17 individuals directly involved in managing the flood recovery programme. The nature of the impact on rural families highlights how the 'hollowing out' of rural New Zealand has changed the capacity of rural communities to respond to natural hazards and increased their sense of isolation. In addition, the floods exposed the vulnerability of rural communities. This is shown to have implications for policies designed to build resilience and improve responses to adverse events, including the need to support local, community initiatives on self-reliance and mutual support. Approaches to manage better long-term flood risks should be designed within a context of ongoing rural decline that has compromised the health of both individuals and communities. 相似文献

Most disaster studies rely on convenience sampling and ‘after-only’ designs to assess impacts. This paper, focusing on Hurricane Harvey (2017) and leveraging a pre-/post-event sample of Greater Houston households (n=71) in the United States, establishes baselines for disaster preparedness and home structure flood hazard mitigation, explores household-level ramifications, and examines how preparedness and mitigation relate to health effects, event exposures, and recovery. Between 70 and 80 per cent of participants instituted preparedness measures. Mitigation actions varied: six per cent had interior drainage systems and 83 per cent had elevated indoor heating/cooling components. Sixty per cent reported home damage. One-half highlighted allergies and two-thirds indicated some level of post-traumatic stress (PTS). Three-quarters worried about family members/friends. The results of generalised linear models revealed that greater pre- event mitigation was associated with fewer physical health problems and adverse experiences, lower PTS, and faster recovery. The study design exposed the broad benefits of home structure flood hazard mitigation for households after Harvey. 相似文献

Flood‐related losses in the United States are increasing despite large‐scale mitigation efforts. To offset the rising cost of floods, the US Congress passed legislation in 2014 that will augment insurance premiums to make the National Flood Insurance Program more actuarially sound. Consequently, there is interest in lowering flood‐related costs to the homeowner, both in terms of premiums and damage. This study addresses the issue by integrating premium savings and damages avoided based on several mitigation scenarios. Specifically, it examines how much policyholders within a watershed near Houston, Texas, could have saved between 1999 and 2009 had their communities introduced specific avoidance‐based mitigation activities. The results indicate that homeowners and communities can offset premium rises and a majority of the damage suffered through marginal expansions of such initiatives. However, the costs associated with their implementation could counter some of these savings, and hence they need to be considered in future work. 相似文献

The United Kingdom has experienced several exceptional summer flash floods in recent years and there is growing concern about the frequency of such events and the preparedness of the population. This paper uses a case study of the upper Ryedale flash flood (2005) and questionnaire and interview data to assess local perceptions of upland flash flooding. Experience of a major flash flood may not be associated with increased flood risk perception. Despite local residents’ awareness of a trend towards wetter summers and more frequent heavy rainfall, the poor maintenance of rivers was more frequently thought to be a more significant factor influencing local flood risk than climate change. Such findings have important implications for the potential success of contemporary national flood policies, which have put greater emphasis on public responsibility for responding to flooding. This study recommends, therefore, the use of fresh participatory approaches to redistribute and raise awareness of locally‐held flood knowledge. 相似文献

This paper evaluates willingness-to-pay (WTP) for flood insurance and floodgate installation in Tainan, Taiwan, and finds that household flood precaution (observing the water level) has a minor effect in terms of increasing the WTP for flood insurance, rather than decreasing it. The reason for this is that people who have public flood protection nearby do not lower their WTP for floodgate and insurance, and those who live near the water source of floods and exhibit precautionary behavior have higher risk perceptions and intend to pay more. The adopted mitigation (having sandbags or other barriers) will not affect the intention to further mitigate or buy insurance. This also means that adverse selection in relation to flood insurance is not serious in the flood-prone area of Tainan. Households may be aware of the limitation of public flood protection though the precautionary behavior, and found that flood insurance can compensate for most of the flood damage. 相似文献

The objective of this paper is to investigate and to improve understanding of the causes and circumstances of flood disaster deaths. A standardised method of classifying flood deaths is proposed and the difficulties associated with comparing and assessing existing information on flood deaths are discussed. Thirteen flood cases from Europe and the United States, resulting in 247 flood disaster fatalities, were analysed and taken as indicative of flood disaster deaths. Approximately two-thirds of the deaths occurred through drowning. Thus, a substantial number of flood disaster fatalities are not related to drowning. Furthermore, males are highly vulnerable to dying in floods and unnecessary risk-taking behaviour contributes significantly to flood disaster deaths. Based on these results, recommendations are made to prevent loss of life in floods. To provide a more solid basis for the formulation of prevention strategies, better systematic recording of flood fatalities is suggested, especially those caused by different types of floods in all countries. 相似文献

The post‐earthquake psychopathological investigation (PEPSI) was designed to probe the short‐and long‐term effects of the earthquake in northern Armenia on 7 December 1988 on survivors' mental and physical health. Four phases of this study have been conducted to date, and, overall, more than 80 per cent of a sub‐sample of 1,773 drawn from an initial cohort of 32,743 was successfully followed during 2012. This paper describes the methodology employed in the evaluation, summarises previous findings, details the current objectives, and examines the general characteristics of the sample based on the most recent follow‐up phase outcomes. Despite a significant decrease in psychopathology rates between 1990 and 2012, prevalence rates of post‐traumatic stress disorder and depression among study participants in 2012 were greater than 15 and 26 per cent, respectively. The paper also notes the strengths and limitations of the study vis‐à‐vis future research and highlights the importance and potential practical implications of similar assessments and their outcomes. 相似文献

Floods are the most common type of natural disaster in both developed and developing countries and have led to extensive morbidity and mortality throughout the world. Worldwide, over the past 30 years, flooding has claimed the lives of more than 200,000 people and affected more than 2.8 billion others. The impact of flooding on health varies among populations and depends primarily on vulnerability and the kind of event experienced. It severely disrupts livelihoods and has a significant impact on the health of pregnant women and children. In addition, it may exacerbate a range of negative psychological and physiological child and reproductive health outcomes. Awareness‐raising, education, and the issuing of warnings appear to be key initiatives to mitigate or prevent flood morbidity and mortality, especially among people living in low‐ and middle‐income countries. Agencies responding to emergencies also need to be more cognisant of the dangers, specifically those engaged in healthcare, nutrition, and water safety programmes. 相似文献

探讨了近3000年来长江中游西部洪水灾害发展的人文因素。古代(3000—700aBP)人口较少,多择地势高的岗地居住,只有少数沿江城市需要堤防保护;长江干流洪水可多处分道散流,所携带泥沙导致云梦泽解体消亡。自宋代开始,低地筑垸围湖,与水争地,但九穴十三口畅通,洪水灾害不严重。明代(700—450a B P)几乎完全堵塞了荆江北流的穴口,荆北大堤联成一体,但堤防薄弱,出现过30次决口成灾。清代以来,随着人口激增,与水争地矛盾加剧,堤防加高培厚,使荆江河道洪水位大幅度上升,溃堤和溃坝洪水灾害较明代成倍出现。同时,历代的“舍南保北”政策迫使长江干流大洪水中过半水量与泥沙向南泄入洞庭湖,曾使洞庭湖面积扩至6000km^2,以后洞庭湖迅速淤积萎缩。1949至1985年间,人口又一次迅速增长,进一步加强围湖垦殖,大量通江湖泊面积萎缩。除1954和1998年那样人所共知的严重洪水灾害外,内涝渍水灾害也非常严重,人类与洪水的矛盾达到了顶点。改革开放后,尤其是三峡大坝的修建,极大地改变了长江中游的水文情势,工业化与城市化的迅猛发展,农村人口压力减轻,而21世纪初期降水相对较少,因此当前相当一段时间长江中游洪水灾害大为缓和。应抓住时机,总结经验,在人地和谐的现代水科学技术理念指导下,制定21世纪前半期,特别是2020年前的长江水利和水资源发展规划,促使人与洪水和谐共处。 相似文献

The purpose of this research was to assess the importance of psychological trauma in understanding reactions to short lead time weather warnings. The research consisted of two case studies, one in Denver, Colorado and the other in Austin, Texas. A total of 61 individuals with 9 or greater traumas were compared to 281 non-trauma exposed individuals. Results demonstrated significant differences on questions related to general beliefs about flash floods and warning perceptions as well as reported anticipated actions during a flash flood at home. Results suggest high trauma exposure may lead to more threat sensitivity and a higher probability of initiated action in a home-based flash flood. 相似文献
