Arts as a vehicle for community building and post‐disaster development

Use of the arts in international aid is common in an ad hoc form, but it has not been systematically theorised or evaluated. The arts have the potential to be a culturally contextualised and sustainable intervention for adults and children in the aftermath of war or disaster. On the micro level, the arts are a method to enable the retrieval and reprocessing of traumatic memories that are often encoded in images rather than in words. On a macro level, they can help to reconstruct a group narrative of a disaster as well as mobilise people back into control of their lives. This paper researches a long‐term project using arts in Sri Lanka following the civil war and tsunami. A central finding is the need to understand arts within their cultural context, and their usefulness in strengthening the voices and problem‐solving capacities of the victims of the disaster.     

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.     

干湿循环对三峡支流消落带沉积物中可转化态氮及其形态分布的影响

水体富营养化的形成与沉积物中氮素的"源-汇"关系密切,本研究选取三峡典型支流澎溪河消落带上、中、下这3个水文断面,160 m和170 m两个水位高程,0~20、20~40、40~60、60~80、80~100 cm共5个深度的沉积物样品,通过研究其总可转化态氮(TF-N)与各形态可转化态氮含量及分布特征,旨在揭示周期性水位变化对消落带沉积物氮释放的影响.结果表明,澎溪河消落带沉积物总氮含量在313.02~3 255.53 mg·kg-1之间,空间分布上呈上站位(渠口)中站位(高阳)下站位(双江)的趋势;总可转化态氮含量范围为288.54~1 123.27mg·kg-1,均值为639.40 mg·kg-1,空间分布趋势与总氮一致;TF-N中各形态氮的大小顺序为:OSF-N(有机态和硫化物结合态)IMOF-N(铁锰结合态)CF-N(碳酸盐结合态)IEF-N(离子交换态).沉积物中TF-N主要以OSF-N(50.9%)和IMOF-N(33.3%)形态存在.OSF-N很难释放,不易参与氮循环.IMOF-N受水文条件影响显著,表现为在低水位高程和下采样站位沉积物中含量更低.淹水胁迫、水体富营养化等情况下氧含量较低,相对还原条件下有利于其向水体释放.而TF-N及其形态分布在垂直深度上无显著差异.可见,三峡库区特殊调蓄水制度加速了澎溪河下游、低水位高程消落带沉积物中IMOF-N向水体的释放.     

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。

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。
