Assessment of disaster resilience capacity of hillslope communities with high risk for geological hazards 总被引:2,自引:0,他引:2

This study presents a novel preparedness assessment method for assessing hazard mitigation and environmental planning of hillslope communities. A professional questionnaire was utilized to weight each indicator. Communities in Hsinchu, Taichung and Nantou counties with debris flow hazards were taken as study samples. Debris flow risk and landslide susceptibility for each community were determined using Geographic Information System (GIS) technology and logistic regression analysis. Thus, a novel risk assessment method for evaluating disaster resilience capacity of hillslope communities was established. This method was then applied to assess casualties caused by Typhoon Herb in 1996 and Typhoon Mindulle in 2004. Additionally, the analytical results generated by this assessment method were discussed with the aim of developing references for implementation of risk analysis, increasing the effectiveness of disaster mitigation, and reducing future loss of life and property. 相似文献

This paper uses the disaster diplomacy framework to address the impact of the 26 December 2004 tsunami disaster on the decades-long conflict between the Free Aceh Movement (GAM) and the Government of Indonesia. This framework enables the identification of a micro-factors of great importance in securing momentum for the peace talks. These factors include informal networks being created, plus disaster relief and diplomacy occurring at multiple levels through multi-way processes and the position of GAM dedicated to reconstruction activities. This paper further shows that, in the case of Aceh, the disaster had a deep influence on the peace talks between GAM and the Indonesian government and on the eventual implementation of the peace agreement reached. However, the tsunami disaster should not be considered the sole vector of peace in Aceh, but as a powerful catalyst in diplomatic talks, since negotiation between both sides were ongoing before the disaster and were favoured by recent changes in the political environment. Twenty-eight months after the tsunami catastrophe, it is actually non-disaster and internal political factors which are likely to have a more significant impact on the long-term resolution of the Aceh conflict. One important outcome is that it appears that the slow, unequal and often poor reconstruction process is not hindering, or even threatening, the peace process because tsunami disaster related factors are less important for peace than non-tsunami disaster related factors, findings in line with previous disaster diplomacy case studies. 相似文献

灾害生态学——生态学的一个重要发展方向 总被引:4,自引:0,他引:4
对灾害生态学有关的基本概念与主要研究内容进行了探讨。认为灾害实际上是一种异常的生态学现象与过程,因此需要从生态学的角度加以研究,特别是要对灾害系统的发生成因、类型、时空分布、发展、危害、预测、控制和灾后恢复等的全过程生态学现象和规律以及相关技术进行研究。同时指出,当今,应围绕重大的全球性环境灾害问题,对其发生与发展的生态学机制与生态学后果,以及减轻、防范这些灾害的关键技术开展研究。 相似文献

Rebuilding of victims' livelihoods was a crucial issue in the restoration process in the1995 Hanshin-Awaji Earthquake Disaster. Housing damage assessment influencedmost of the rebuilding of the livelihood in the long term, because the Victim Certificatesissued by the local governments based on the results of the Housing damage assessmentwas required to receive most of the individual assistance measures. In the process ofHousing damage assessment, many complex problems arose, leading to extensivework on the part of the disaster responders. Consequently, a considerable number ofvictims were dissatisfied with the assessment and applied for a resurvey. Due to a floodof requests for resurvey, disaster responders had to work on damage assessment, leavingrelief activities aside.In order to facilitate Housing damage assessment, this paper discusses thefollowing five points: (1) the processes and the problems of assessments performedin the Hanshin-Awaji Earthquake Disaster, (2) the changes in the nature of informationneeded by the victims, (3) the improvements over the present damage assessment, (4)the housing situation in Japan, and (5) the international situation on damage assessment.It is obvious from the results that a poor damage assessment system and the size ofthe disaster produced a very large work load. Differences in appreciation among theinvestigators also contributed to unfair assessments and led to the victims beingincreasingly dissatisfied by the survey results. Finally, a design concept for acomprehensive damage assessment system, which has been derived from theabove five points, is proposed for post-disaster management. 相似文献
