Environmental damage: distinguishing human from geophysical causes

Abstract

During the past two decades it has become increasingly common to attribute “naturala” disasters and other damaging environmental events to proximate or underlying causes that are socially produced. Through an examination of three cases, two of them historical, this paper demonstrates that underlying causes within the geophysical domain are also important. Few types of environmental damage or disaster stem from unalloyed human causes or geophysical ones; complex intermixtures are the rule.     

Research on Methods for Building Volcano Disaster Information System--taking Changbai Mountain as an example

1IntroductionAs a many-volcano-distributed country,China is covered with many volcanoes and lava rocks.A-mong the one-thousand-or-so volcanoes,Changbai Mountain Volcano,Wudalianchi Volcano,Tengchong Volcano and Ashikule Volcano of West Kunlun are the mostlatentcatastrophic erup-tive active volcanoes.In recent years,the activity of the earth' s crust in some volcanic areas isobviously becoming increasing violent.Butfew scholars have monitored and evaluated volcano inChina.So building VDI…     

A review of public acceptance of nature-based solutions: The ‘why’, ‘when’, and ‘how’ of success for disaster risk reduction measures

Nature-based solutions (NbS) are increasingly recognized as sustainable approaches to address societal challenges. Disaster risk reduction (DRR) has benefited by moving away from purely ‘grey’ infrastructure measures towards NbS. However, this shift also furthers an increasing trend of reliance on public acceptance to plan, implement and manage DRR measures. In this review, we examine how unique NbS characteristics relate to public acceptance through a comparison with grey measures, and we identify influential acceptance factors related to individuals, society, and DRR measures. Based on the review, we introduce the PA-NbS model that highlights the role of risk perception, trust, competing societal interests, and ecosystem services. Efforts to increase acceptance should focus on providing and promoting awareness of benefits combined with effective communication and collaboration. Further research is required to understand interconnections among identified factors and how they can be leveraged for the success and further uptake of NbS.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01502-4.     

基于GIS的断层构造对滑坡灾害发育控制作用分析——以雅安市雨城区为例

断层是滑坡发育的影响因素之一。选择雅安市雨城区和区域内232处滑坡作为研究的基础资料,通过地理信息系统空间分析技术及作者提出的滑坡影响因子贡献率的方法,得到了研究区内断层100m和200m缓冲区对滑坡的贡献率,定量研究了断层对研究区域滑坡发育的关系。研究结果表明,研究区域断层对滑坡敏感性不大,100m断层缓冲区较200m断层缓冲区贡献率值较大,为下一步研究区域滑坡危险度区划奠定了基础,同时为区域防灾提供了科学依据。     

论灾害风险研究中的空间尺度耦合

作为人地关系中"地"对"人"负面作用的核心学科——灾害风险学存在着显著的地理空间尺度差异与尺度效应。本文提出灾害风险尺度耦合的概念与类型,从数据、方法和区划三个方面提出灾害风险研究中的空间降尺度和空间升尺度耦合思路,供同行学者参考。     

日本9.0级特大地震应急救援与灾后重建对我国的启示

本文简要阐述了日本9.0级特大地震的应急救援和灾后重建情况,总结其成功经验与失败教训。并详细分析了日本防灾救灾法律体系、防灾救灾组织管理系统和保险制度等。旨在广泛吸纳日本社会在防震减灾方面的成功模式和经验,形成具有中国特色的现代化防震减灾机制,从而进一步加快我国的防震减灾体系的建设。     

自然灾害脆弱性研究进展

自然灾害风险研究是当今国际社会、学术界普遍关注的热点问题。本文在回顾国内外自然灾害脆弱性研究发展的基础上,阐述了自然灾害脆弱性的基本内涵,通过对国内外自然灾害脆弱性研究尺度、评价模型、评估方法等方面进行对比,指出国内自然灾害脆弱性研究存在的问题。同时指出未来自然灾害脆弱性研究的发展趋势应加强对人-地耦合系统的脆弱性研究,以及对其内在形成机制和发生演变规律的研究。自然灾害脆弱性研究是涉及多学科、多领域的复杂研究课题,并且呈现出多学科交融的趋势,需要综合考虑自然和社会双重因素的影响。     

论民初我国救灾之主要特征

民国初年我国救灾的主要特征有三:一是救灾主体多元化,这可从阶层、国籍、职业、身份等方面看出,总体上又可划分为政府和社会力量两个方面。至于救灾效能,无论是政府还是社会救济力量均存在着或多或少的局限性。二是短效机制占主导,这可从救灾因素之临设性、救灾甚于防灾两点看出。三是社会过渡性彰显,无论是思想,还是机构、制度,都呈现出明显的新旧交错性,即社会过渡性。     

大学生减灾教育对策研究

灾害风险认知能力是进行减灾教育的基础,受众获取灾害知识与信息的方式是影响减灾教育方法的重要因素,而受众获取灾害知识与信息的途径则会直接影响灾害内容的传递效率和效果。本文针对以上所关心的问题,为了建立合理有效的大学生减灾教育计划,应对大学生防灾减灾意识和能力不足的现状,通过问卷调查,分析和研究了来自不同生源地大学生的灾害风险认知水平、获取灾害知识和信息的方式与途径。从自然灾害风险认知的视角,通过寻找不同特性大学生群体获取减灾知识与信息的差异和趋同性,提出了现势条件下针对大学生的减灾教育对策。
