首都大学生的自然灾害认知调查与减灾教育建议

2006年国际减灾日的主题是"减灾始于学校",了解学生的灾害认知水平有助于减灾教育工作的有效开展。以北京5所高校的大学生为调查对象,通过问卷方式调查大学生对自然灾害的关注程度、防灾意识、灾害理论知识、应急行为知识以及对减灾教育的看法。问卷统计结果表明:大学生总体的灾害认知水平较低,现行减灾教育方式和内容与学生的期望有较大偏差。在此基础上,提出了减灾教育内容要将学生"该知道的"与"想知道的"相结合,通过演练演习等方式提高学生的防灾应急实际技能等减灾教育建议。     

International Strategy of Disaster Reduction (ISDR) and Integrated Disaster Reduction in China

At the beginning of the 21st century, while we are recalling the glorious achievements and progress mankind has achieved in the last century, we can not help thinking about the catastrophic wars, natural disasters and epidemic diseases that have caused serious impacts and damages to humanity.

Natural disasters: a framework for research and teaching

Natural disasters are defined in this paper by relating the impact of extreme geophysical events to patterns of human vulnerability. Hazard perception is shown to be a factor that limits the mitigation of risk. The historical development of disaster studies is traced and five different schools of thought are identified. The current International Decade for Natural Disaster Reduction (IDNDR) is evaluated critically with regard to its potential for unifying the disparate strands of knowledge and its scope as a vehicle for education.
A pedagogical framework for disaster studies is presented. Time and space provide valuable unifying factors, while the subject matter can be differentiated according to the continua and dichotomies that it presents. In disaster studies as in other branches of higher education, an ecocentric approach is preferable to a technocentric one, as many of the poorer nations of the world, which are most afflicted by natural catastrophe, will have to rely for mitigation on maintaining their ecological sustainability, instead of depending on sophisticated technology. Valuable insights into the impact of environmental extremes on mankind are gained from the study of disasters as human ecology.     

自然灾害基本定义的探讨

自然灾害的研究,正在变为一门热门的学科.然而,大多数人是通过举例来回答"什么是自然灾害?"这一问题,一些学者则干脆对此避而不谈.显然,如果对"自然灾害"这一概念没有严格的定义,如果人们只热衷于提出各种概念模型,热衷于案例分析,则"自然灾害学"就很难上升为一门科学内核清楚的学科.从分析定义的本质人手,梳理出下定义的4条规则,指出了现有5个自然灾害定义的不足之处,建议了一个自然灾害的基本定义,并用它分别对<国家综合减灾"十一五"规划>中提及的13种自然灾害进行了界定.     

Normalised insurance losses from Australian natural disasters: 1966–2017

ABSTRACT

The paper updates normalisation of the Insurance Council of Australia’s Disaster List in the light of debate about the contribution of global warming to the rising cost of natural disasters. Normalisation estimates losses from historical events in a common year, here ‘season’ 2017 defined as the 12-month period from 1 July 2017. The number and nominal cost of new residential dwellings are key normalising factors and post-1974 improvements in construction standards in tropical cyclone-prone parts of the country are explicitly allowed for. 94% of the normalised losses arise from weather-related perils – bushfires, tropical cyclones, floods and severe storms – with the 1999 Sydney hailstorm the most costly single event (AUD5.6 billion). When aggregated by season, there is no trend in normalised losses from weather-related perils; in other words, after we normalise for changes we know to have taken place, no residual signal remains to be explained by changes in the occurrence of extreme weather events, regardless of cause. In sum, the rising cost of natural disasters is being driven by where and how we chose to live and with more people living in vulnerable locations with more to lose, natural disasters remain an important problem irrespective of a warming climate.     

自然灾害综合研究的回顾与展望

回顾了20世纪90年代以来,我国在自然灾害综合研究方面所做的工作和取得的成果以及所获得的新认识,包括将研究由单类推向综合。提出自然灾害系统和灾害科学体系的新观念,探索自然灾害综合预报,加强灾害社会属性的研究;提出分区减灾、分级减灾的对策,倡导开展减灾系统工程,将减灾纳入可持续发展系列建立减灾管理系统,推动减灾社会化与产业化等。对21世纪自然灾害综合研究进行了展望,认为其基本指导思想应为从自然灾害系统研究扩展为环境-灾害系统研究。同时提出了减灾能力评估、综合区划、灾后重建统筹规划等所面临的重大问题。     

The role of the media in hazard mitigation and disaster management

The International Decade for Natural Disaster Reduction, which began in January 1990, will embrace efforts to reduce death, injury and property losses stemming from rapid-onset natural disasters. Our expanding science and technology base makes possible this concerted cooperative international effort, and communications is a central part of that effort — for public education, early warning, evacuation and coordination of post-disaster relief. Mass communication is inextricably entwined with disasters and hazard mitigation. Reflecting the public's great interest and concern, the electronic and print media extensively cover natural disasters and significantly affect how and what the public learns about and how it perceives natural hazards. Improving the linkages between the media and disaster-mitigation researchers and practitioners could prepare the public to act promptly on warnings, helping to mitigate disasters. This could also accelerate the shift of the societal emphasis from post-disaster relief toward pre-disaster initiatives.     

ENSO and Disaster: Droughts, Floods and El Niño/Southern Oscillation Warm Events

The connection between El Niño/Southern Oscillation (ENSO) events and precipitation and temperature variability worldwide is increasingly well understood. ENSO has been linked to droughts and flooding in some regions. This paper uses the disaster history database of the U.S. Agency for International Development's Office of U.S. Foreign Disaster Assistance to examine the link between ENSO events and droughts or floods of sufficient magnitude to trigger international disasters. Worldwide, disasters triggered by droughts are twice as frequent during year two of ENSO warm events than during other years. No such relationship is apparent in the case of flood disasters. Drought disasters occur during year two of ENSO warm events significantly more frequently than in other years in Southern Africa and Southeast Asia. No regional pattern emerges from a comparable analysis of flood disasters. Those places likely to be affected by ENSO-triggered droughts can take proactive measures to mitigate the impacts.     

Disaster risk,social vulnerability,and economic development

This paper examines the extent to which economic development decreases a country's risk of experiencing climate‐related disasters as well as the societal impacts of those events. The paper proceeds from the underlying assumption that disasters are not inherently natural, but arise from the intersection of naturally‐occurring hazards within fragile environments. It uses data from the International Disaster Database (EM‐DAT), 1 representing country‐year‐level observations over the period 1980–2007. The study finds that low‐income countries are significantly more at risk of climate‐related disasters, even after controlling for exposure to climate hazards and other factors that may confound disaster reporting. Following the occurrence of a disaster, higher income generally diminishes a country's social vulnerability to such happenings, resulting in lower levels of mortality and morbidity. This implies that continued economic development may be a powerful tool for lessening social vulnerability to climate change.     

我国近年农业气象与农业生物灾害的特点

以1999,2000,2003,2004,2005,2006和2007年各省份(包括直辖市、自治区,下同)单位播种面积的成灾面积比例与全国的均值相比较,计算了各省这7年中各灾害的成灾指数。结果表明:(1)全国有12个省份的旱灾情况重于全国平均水平,其中内蒙古、甘肃、辽宁旱灾最为严重,成灾指数在2.5以上。(2)有10个省份洪涝灾重于全国平均水平,洪涝灾严重的4个省份依次是湖北、重庆、安徽、湖南。(3)有8个省份风雹灾情况重于全国平均水平,灾害严重的依次是浙江、北京、海南、青海、河北。(4)有7个省份台风灾情况重于全国平均水平,5个灾害严重的省份依次是浙江、海南、广东、福建、广西。(5)有6个省份低温冻害情况重于全国平均水平,5个严重省份依次是宁夏、青海、甘肃、内蒙古和湖北。(6)有10个省份农作物病虫害受灾情况重于全国平均水平,4个严重的省份依次是上海、江苏、浙江、河北。(7)有16个省份农田草害情况重于全国平均水平,农田草害严重的6个省份依次是山东、湖南、江苏、河北、北京、浙江。(8)有15个省份农田鼠害情况重于全国平均水平,其中4个省份为重灾,依次是北京、吉林、青海、重庆。北京历年受灾最为严重,成灾指数平均在3.4以上。因此,我国各种自然灾害的主要分布地区和省份变化较大,各地区和省份应根据当地发生的主要灾害,采取有针对性的防治对策。     

A scenario-based study on information flow and collaboration patterns in disaster management

Disaster management (DM) is a continuous, highly collaborative process involving governments, DM organisations, responders, the construction sector, and the general public. Most research approaches to DM include the development of information and communication technologies (ICT) to support the collaboration process rather than the creation of a collaboration process to provide information flows and patterns. An Intelligent Disaster Collaboration System (IDCS) is introduced in this paper as a conceptual model to integrate ICT into DM and the mitigation process and to enhance collaboration. The framework is applicable to the collaboration process at the local, regional and national levels. Within this context, the deployment of ICT tools in DM is explored and scenario-based case studies on flooding and terrorism—examples of natural and human-induced disasters, respectively—are presented. Conclusions are drawn regarding the differences found in collaboration patterns and ICT used during natural and human-induced disasters and the differences between currently available ICT and proposed ICT.     

1368-1948年山西霜雪灾害的特征与周期规律研究

通过对山西1368-1948年历史文献资料的搜集、整理和数学分析,对该区霜雪灾害等级、阶段、周期及其成因进行了研究。在这期间,山西共发生霜雪灾害419次,轻度106次、中度228次、重度85次。灾害变化可分为4个阶段,1368-1579年为第1阶段,1580-1699年为第2阶段,1700-1819年为第3阶段,1820-1948年为第4阶段。第1、3阶段距平值主要为负值,灾害频次较低,以轻、中度灾害为主。第2、4阶段距平值主要为正值,灾害频次较高,以中度和重度霜雪灾为主。小波分析表明,灾害存在着4个明显的周期,即10～13年、20年左右、45～50年和120年左右的周期。降雪或寒流引起的气温骤降至0℃以下是造成山西霜雪灾害的主要原因。共发生6次寒冷气候事件,分别出现在1578-1588、1591-1607、1631-1642、1669-1672、1690-1699和1830-1836年。出现3次异常寒冷灾害年,分别是1653、1892和1929年。     

Gauging the societal impacts of natural disasters using a capability approach

There is a widely acknowledged need for a single composite index that provides a comprehensive picture of the societal impact of disasters. A composite index combines and logically organizes important information policy‐makers need to allocate resources for the recovery from natural disasters; it can also inform hazard mitigation strategies. This paper develops a Disaster Impact Index (DII) to gauge the societal impact of disasters on the basis of the changes in individuals’ capabilities. The DII can be interpreted as the disaster impact per capita. Capabilities are dimensions of individual well‐being and refer to the genuine opportunities individuals have to achieve valuable states and activities (such as being adequately nourished or being mobile). After discussing the steps required to construct the DII, this article computes and compares the DIIs for two earthquakes of similar magnitude in two societies at different levels of development and of two disasters (earthquake and wind storm) in the same society.     

Revealing the socioeconomic impact of small disasters in Colombia using the DesInventar database

Small disasters are usually the product of climate variability and climate change. Analysis of them illustrates that they increase difficulties for local development—frequently affecting the livelihoods of poor people and perpetuating their level of poverty and human insecurity—and entail challenges for a country's development. In contrast to extreme events, small disasters are often invisible at the national level and their effects are not considered as relevant from a macroeconomic standpoint. Nevertheless, their accumulated impact causes economic, environmental and social problems. This paper presents the results of an evaluation of the DesInventar database, developed in 1994 by the Network for Social Studies in Disaster Prevention in Latin America. In addition, it proposes a new version of the Local Disaster Index developed in 2005 within the framework of the Disaster Risk and Management Indicators Program for the Americas, with the support of the Inter‐American Development Bank.     

Natural hazard events and social capital: the social impact of natural disasters

This study investigates if and to what extent natural disasters affect social capital. Twelve different events in Europe are examined in a quantitative analysis, using data derived from the European Social Survey and the EM‐DAT International Disaster Database. The study uses social trust as an indicator of social capital and offers evidence that a change in social trust is a possible occurrence during or after a disaster, but that it is not an inevitable consequence of it. The results reveal that social trust decreases after a disaster with a death toll of at least nine. Changes in social capital, therefore, are found to be more probable as the severity of the event increases. National, rather than regional, disasters lead more frequently to significant shifts in social trust. This evaluation of 12 separate cases pinpoints several disasters that have had an effect on social trust, but it does not identify any general patterns, underlining the significance of contextual dependency.

加强综合灾害风险研究,提高迎对灾害风险能力——从第6届国际综合灾害风险管理论坛看我国的综合减灾

综述了第6届国际IIASA-DPRI综合灾害风险管理论坛的主要内容，并就中国综合灾害风险管理对策提出了具体的建议。本届论坛的主题是：风险与商业和产经界面临的挑战。论坛除主题报告外，共设置了16个分会场，就综合灾害风险信息共享平台（DRH）的建设、产经界如何迎对灾害风险、地震与洪水灾害风险的综合管理、灾害风险教育与减灾意识的养成、综合灾害风险管理的理论与方法论探讨，以及土耳其国家综合灾害风险管理的经验与教训等进行了深人的研讨。针对上述进展，从我国减灾工作现状，提出从三个方面加强我国综合减灾与灾害风险管理工作，即：各级政府在加强应急管理工作的同时，要高度重视从综合的角度完善减灾战略、规划和能力建设；全面改进产经界迎对灾害风险的能力，特别是非国有中小企业防御灾害风险的能力，以及大型国有企业灾害自保或参保机制的完善；加强综合灾害风险管理研究。     

Protecting cultural assets from bushfires: a question of comprehensive planning

Cultural heritage sites form an unrenewable asset that is threatened by natural disasters. Given the high bushfire risk, mandatory Bush Fire Risk Management Plans have been drawn up throughout New South Wales, Australia. We compared their mandatory provisions for the protection of heritage assets with an 'Ideal Heritage Disaster Plan', containing a series of non-negotiable elements. The examined plans fell well short of the ideal. Preparedness Plans generally lacked a discussion of suppression techniques (for historic heritage), prevention, prescribed drills and communication procedures. None of the Response Plans or Recovery Plans contained any of the required core elements, such as rapid suppression techniques and stabilisation procedures. Where aspects were covered, they were addressed in an inadequate level of detail. The overall quality of the cultural heritage components of the plans is judged to be poor. Suggestions are made on how to improve the situation if heritage assets are to have a future following bushfire events.
