区域水灾恢复力及水灾风险管理研究——以湖南省洞庭湖区为例

近年来灾害恢复力研究在领域的拓展和定义的延伸等方面取得了较大的进步。灾害恢复力作为系统的一个有价值的属性，与风险、脆弱性和适应性一起成为当前灾害综合管理和减灾研究的重要内容。但目前灾害恢复力研究仍停留在理论和概念层面，鲜有深入的实际操作性强的工作开展。为进一步理解水灾恢复力的内涵和实质，为区域恢复力建设提供切实可行的方案，作者在原有对灾害恢复力研究进展进行综述的基础上，开展了以湖南省洞庭湖区为例的洪水高风险区水灾恢复力理论和实践的研究，提出了由自然维、经济维、组织维、社会维组成的四维区域水灾恢复力概念模型，然后细致分析了区域水灾恢复力利益主体的相互关系，提供了初步的区域水灾恢复力评估模型。最后在定性分析的基础上，对洞庭湖区区域水灾风险管理进行了探讨，提出了相应的管理对策和建议，旨在为政府的防灾减灾决策提供科学依据。     

基于GIS技术的洪涝灾害风险评估与区划研究--以辽河中下游地区为例

目前,对洪涝灾害风险的评价方法虽然不少,但还没有能提出一个集成化的指数来对其进行分析.综合考虑了形成我国东北地区洪涝灾害风险的4个因子,以辽河中下游地区为研究对象,基于GIS技术和自然灾害风险评估方法,从气象学、地理学、灾害科学、环境科学等学科观点出发,提出了洪涝灾害风险指数,用其来评估不同县相关损失风险及各因子对风险的贡献,并绘制出了辽河中下游洪涝灾害风险区划图.     

基于GIS/AHP集成的洪水灾害综合风险评价——以淮河流域为例

根据影响洪水灾害风险的致灾因子危险性、孕灾环境稳定性与承灾体易损性,以淮河流域为示范研究区,以县为行政单元,综合考虑降雨、径流量、河流、地形、人口、经济等指标,基于GIS与AHP集成方法得到了淮河流域洪水灾害危险性评价图和淮河流域洪水灾害脆弱性评价图,并采用"加"模型计算公式得到了洪水灾害综合风险评价图,进行了相应的结果分析。     

西藏高原基础设施建设规划的生态风险评价——以西藏山南地区为例

西藏高原脆弱区内的基础设施建设对区域内的生态与环境产生了重大胁迫，因此在完成基建规划编制后，需要评估规划中潜在的生态风险。以西藏山南地区小康示范县为研究区域，对基建规划进行了生态风险评估，结果表明：（1）生态风险区和自然生态脆弱区呈带状分布，略呈对称形，但二者的强度分布相反；（2）基建对轻度脆弱区的干扰最为强烈，与雅江宽谷区的人口快速增长和社会经济最为活跃相对应，区内的灌丛草原和亚高山草原生态系将受到严重胁迫；（3）基建工程对土壤结构、植被、水土保持、高原景观和局部地质条件等构成很大威胁，道路、给排水和农牧水利工程的扰动面积较大；（4）生态与环境规划应当与基建规划衔接，要关注基建工程对区域景观格局及高原生态系统的长期影响，并提出相应预警措施。     

Effects of the 2008 flood on economic performance and food security in Yemen: a simulation analysis

Extreme weather events such as floods and droughts can have devastating consequences for individual well being and economic development, in particular in poor societies with limited availability of coping mechanisms. Combining a dynamic computable general equilibrium model of the Yemeni economy with a household‐level calorie consumption simulation model, this paper assesses the economy‐wide, agricultural and food security effects of the 2008 tropical storm and flash flood that hit the Hadramout and Al‐Mahrah governorates. The estimation results suggest that agricultural value added, farm household incomes and rural food security deteriorated long term in the flood‐affected areas. Due to economic spillover effects, significant income losses and increases in food insecurity also occurred in areas that were unaffected by flooding. This finding suggests that while most relief efforts are typically concentrated in directly affected areas, future efforts should also consider surrounding areas and indirectly affected people.     

Women's invisible work in disaster contexts: gender norms in speech on women's work after a forest fire in Sweden

The aim of this study is to investigate what women do in disaster situations and how both men and women perceive and discuss the work of women. These patterns were evidenced in the stories that were told following the largest forest fire in the modern history of Sweden in July 2014. The study is based on 31 retrospective interviews with volunteers involved in combating the forest fire and concentrates on stories about the supportive work of women during this disaster. The results indicate that women were praised when they followed traditional norms but were denigrated when they performed what were viewed as male-coded tasks. The stories reveal norms concerning what a woman is and is not by focusing on women's age and clothing and by directly and indirectly questioning their abilities and authority. The norms are also rendered visible by the positive attention that women receive while describing doing what is expected of them.     

Climate change implications for disaster risk management in Japan: A case study on perceptions of risk management personnel and communities in Saijo city

This paper reviews climate change impacts and the existing disaster risk management system in Japan and offers the results of a structured questionnaire survey of the community leaders and disaster risk management personnel of Saijo city of Japan that assesses their perceptions about dealing with the extreme disasters by the existing disaster risk management systems. This study was inspired by the record number of typhoon landfall that has surprised the local government and communities in 2004. While unearthing the hidden vulnerabilities in cities like Saijo, this event has loosened the confidence of local communities on the disaster risk management systems. From the study, we conclude that the existing disaster risk management systems need further fillip and that the proactive community involvement in disaster risk management is still in nascent stages. Associating with the scientific community, involving the local communities (including the elderly), enhancing the redundancy in disaster risk management systems, inculcating strategic thinking and micro-level planning, conducting vulnerability assessments by considering the special circumstances including resource constraints of small cities and better policy coordination across the administrative hierarchy are some important considerations for dealing with the uncertainty brought by the extreme events.
