基于GIS的区域干旱灾害风险区划研究

根据自然灾害风险理论,从致灾因子危险性、孕灾环境暴露性、承灾体易损性、防灾减灾能力等4个子系统选取指标,建立干旱灾害风险指数模型,结合GIS中自然断点分类法进行聚类分析,全面综合地分析各地区相关性和差异性.以淮河流域为研究实例,根据拟定的区划原则,采用“自下而上”和“自上而下”相结合的区划方法,将淮河流域分为6个旱灾风险分区,并对区划结果进行分析,为因地制宜地采取工程和非工程的防灾减灾措施,提供参考依据.     

日光温室黄瓜低温冷害风险评估技术研究

基于人工气候箱和大田试验观测结果,探讨了日光温室黄瓜生产低温冷害气象指标确定技术,将冬季黄瓜生产低温冷害分为无灾、轻灾、中灾和重灾4个等级,利用层次分析法和GIS技术,对日光温室黄瓜生产低温冷害综合风险进行评估.结果表明,山东省各级冷害出现日数随着低温冷害程度的加重呈减少的趋势,但区域间存在一定差异.鲁北、鲁西北北部、鲁中北部以及半岛内陆地区遭受低温冷害风险较高,半岛东部沿海、鲁西南、鲁南及鲁东南沿海区域风险较低,其他地区属于中度风险.

Sovereign financial disaster risk management: The case of Mexico

In 2006, Mexico became the first transition country to transfer part of its public-sector natural catastrophe risk to the international reinsurance and capital markets. The Mexican case is of considerable interest to highly exposed transition and developing countries, many of which are considering similar transactions. Risk financing instruments can assure governments of sufficient post-disaster capital to provide emergency response, disaster relief to the affected population and repair public infrastructure. The costs of financial instruments, however, can greatly exceed expected losses, and for this reason it is important to closely examine their benefits and alternatives. This paper analyzes the Mexican case from the perspective of the risk cedent (the Ministry of Finance and Public Credit), which was informed by analyses provided by the International Institute for Applied Systems Analysis (IIASA). The rationale for a government to insure its contingent liabilities is presented along with the fiscal, legal and institutional context of the Mexican transaction. Using publicly available data, the paper scrutinizes the choice the authorities faced between two different risk-transfer instruments: reinsurance and a catastrophe bond. Making use of IIASA's catastrophe simulation model (CATSIM), this financial risk management decision is analyzed within the context of a public investment decision.     

Communities and bushfire hazard in Australia: More questions than answers

The issue of communities and their exposure to bushfire hazard is highly topical internationally. There is a perceived trend of greater exposure to bushfire risk which is exacerbated by increased levels of building in fire-prone areas or peri-urban regions. There is a need to clarify what we understand to be peri-urban regions, and how we conceptualise and describe the communities that reside in them, in order that efficient and effective services are provided. However, more questions arise for us. For example: Where are these communities located? What do we know about the people who live there? What are the implications for bushfire mitigation? Despite being problematic, locality remains important to the understanding of communities, bushfire hazard and delivery of services.     

Capacity development for participatory disaster risk assessment

In this paper a large-scale community-based disaster risk-assessment project, undertaken in the Dr Kenneth Kaunda District Municipality in the North-West Province of South Africa, is evaluated. In contrast to other disaster risk management consultancy projects in South Africa, this project included a significant skills transfer component to the at-risk communities and local government officials. In this evaluation, the authors draw on their own experiences in implementing this and similar projects, a review of the project management documents is undertaken, and a focus group interview with facilitators involved in the project is used as a primary source. The discussion is further contextualised in terms of community-based disaster risk assessment theory and the existing literature on disaster risk assessment in South Africa. Logistical and data quality issues as well as staff turnover were found to be concerns during the project. From the findings, it is argued that the common practice of outsourcing disaster risk-management projects is not conducive to effective disaster risk management. Local government entities should take responsibility for disaster risk assessment as a continual activity. This is in contrast to the view currently manifesting in South Africa as a set of bureaucratic actions undertaken by consultants to achieve ‘legislative compliance’ for municipalities.     

A fresh perspective on food safety in Canada: risk communication,public involvement,and the impact of the 2008 listeriosis outbreak

While the listeriosis outbreak of 2008 brought attention to food safety decision making in Canada, little of that attention was placed on public involvement and risk communication. With a primary focus on Health Canada (HC) and the Canadian Food Inspection Agency (CFIA), this article describes the state of microbial-related public involvement and risk communication undertakings and suggests ways in which improvements can be made. The findings show that public involvement and risk communication activities have been strengthened since the outbreak, but they have become neither dialogical nor highly participatory. HC engages with experts to a far greater extent than with the lay public and it has fallen short in fulfilling its stated commitment to openness and transparency. Furthermore, both HC's and the CFIA's approach to risk communication has been overly general, has failed to provide opportunities for dialogue with vulnerable and more general groups with whom it is communicating and is not rooted in foodborne surveillance data. Public involvement in food safety governance would be improved if HC provided the lay public with a seat on advisory committees and improved its public involvement reporting methods. HC and the CFIA could also make risk communication improvements by creating opportunities for dialogue between officials and the general public, and by exploring alternative risk communication vehicles, such as food labels.     

北京山区泥石流灾害保险的风险评判方法研究

泥石流是北京山区主要的自然灾害,在1989-1999年期间,泥石流灾害造成的经济损失高达3.09亿元.对泥石流灾害保险风险的评判是首先按北京山区各区县的泥石流危险度分区划分风险区,然后对各风险区进行灾害危险性和灾害易损性评判.在危险性评判中,按各风险区的泥石流危险度等级赋予危险度评判指标值.在易损性评判中,选择国内生产总值、固定资产、人口密度和人口自然增长率等4个因素作为评判指标,并分为两个层次进行评判.第一层次是经济易损性与社会易损性评判,第二层次是泥石流灾害易损性评判.最后用泥石流灾害保险风险分析数学模型,计算出各风险区的泥石流灾害保险风险度,并由此绘制了北京山区泥石流灾害保险风险区划图.     

沿海和内陆地区居民汞暴露量对比

通过对沿海和内陆居民食用水产品消费情况调查以及居民头发汞含量的分析,对不同地区普通居民的汞暴露水平进行了对比研究.居民水产品的消费情况采用调查问卷的形式,对沿海地区大连和内陆地区河南两地普通居民进行了随机调查,并同时采集被调查者的头发作为汞暴露情况的生物样本.本次研究共收集到有效调查问卷及头发样本213份(大连112份;河南101份),两地居民水产品消费量分别为:大连104 g.d-1,河南74 g.d-1;收集到的头发样本采用DMA-80测汞仪(按美国EPA-7473的方法)进行总汞含量的测定.头发总汞含量分析结果显示,大连为(0.363±0.256)μg.g-1,河南地区为(0.192±0.167)μg.g-1.两地区对同一年龄段居民发汞水平比较发现,大连地区居民发汞水平明显高于河南地区.以美国环境保护署(EPA)参考剂量1μg.g-1作为发汞基准,大连地区的超出比例为3%,河南地区的超出比例为1%.该研究结果为了解我国普通居民的汞暴露情况以及后续的汞暴露风险的定量计算提供了基础数据.
