This issue of Disasters explores the roles of NGOs and other actors in disaster mitigation and preparedness and also reviews broad international trends in risk management and disaster prevention. The need to address risk, and with that the motivation to improve disaster mitigation and preparedness, has tended to fall between the cracks of grander frameworks of development co-operation and humanitarian assistance. Despite the seemingly glaring need to reduce the horrific impact of floods, droughts and wars, disaster mitigation and preparedness have neither the allure of directly 'saving lives', nor of providing an 'escape from poverty'. There are, however, signs that risk management is becoming a mainstream concern. Factors such as the need to address factors that do not fit into traditional slots on the relief-development continuum, the rising economic costs of disasters and a growing acknowledgement that aid will never cover more than a small fraction of the costs of disasters are all leading to new approaches, priorities and institutional configurations. A realisation that dealing with risk and insecurity is a central part of how poor people develop their livelihood strategies has begun to position disaster mitigation and preparedness within many poverty alleviation agendas. A number of long-standing challenges remain; most of all, the complexities of maintaining the political will that is needed to ensure that risk management becomes more than a passing fad. 相似文献

随着经济发展和城市化进程的不断加快,城市火灾事故不断增多,造成的人员伤亡和财产损失也越来越严重。本文通过构建城市火灾风险评价指标体系,利用GIS中的空间分析功能对各指标体系按其权重进行叠加,得出城市的现状火灾风险等级区划图。根据风险评价现状确定防灾减灾规划的目标,采取相应的防灾减灾措施,并对规划后的火灾风险状况进行了预测,得出规划后的火灾风险等级,从而为消防和规划部门减少和预防城市火灾提供依据和参考。 相似文献

Assessing the impact of the Indian Ocean tsunami on households: a modified domestic assets index approach 总被引:1,自引:0,他引:1

This paper offers a potential measurement solution for assessing disaster impacts and subsequent recovery at the household level by using a modified domestic assets index (MDAI) approach. Assessment of the utility of the domestic assets index first proposed by Bates, Killian and Peacock (1984) has been confined to earthquake areas in the Americas and southern Europe. This paper modifies and extends the approach to the Indian sub‐continent and to coastal surge hazards utilizing data collected from 1,000 households impacted by the Indian Ocean tsunami (2004) in the Nagapattinam district of south‐eastern India. The analyses suggest that the MDAI scale is a reliable and valid measure of household living conditions and is useful in assessing disaster impacts and tracking recovery efforts over time. It can facilitate longitudinal studies, encourage cross‐cultural, cross‐national comparisons of disaster impacts and inform national and international donors of the itemized monetary losses from disasters at the household level. 相似文献

The impact of the 2004 tsunami on coastal Thai communities: assessing adaptive capacity 总被引:1,自引:0,他引:1
Paton D Gregg CE Houghton BF Lachman R Lachman J Johnston DM Wongbusarakum S 《Disasters》2008,32(1):106-119
The suddenness and scale of the 26 December 2004 tsunami and the challenges posed to affected communities highlighted the benefits of their members having a capacity to confront and adapt to the consequences of such a disaster. Research into adaptive capacity or resilience has been conducted almost exclusively with Western populations. This paper describes an exploratory study of the potential of a measure of collective efficacy developed for Western populations to predict the capacity of members of a collective society, Thai citizens affected by the 2004 tsunami, to confront effectively the recovery demands associated with this disaster. Following a demonstration that this measure could predict adaptive capacity, the role of religious affiliation, ethnicity and place of residence in sustaining collective efficacy is discussed. The implications of the findings for future research on, and intervention to develop, adaptive capacity among Thai citizens in particular and collectivist societies in general are discussed. 相似文献

我国海岸带灾害成因分析及减灾对策 总被引:14,自引:1,他引:14
近年来海岸带灾害越来越成为制约海岸带-我国最重要的经济带社会、经济和环境可持续发展的重要因素。本文在全球变化和人类活动影响的背景下,分析探讨了我国海岸带灾害的基本成因,并提出了相应的概念性减灾对策框架,海岸带生态环境的脆弱性,全球变化(相对海平面变化、气候异常)和人类活动是导致我国海岸带灾害的3个主要方面。据此,认为减灾的关键在于合理规范人类行为,保护和改善本已十分脆弱的海岸带生态环境,使人与自然界和谐相处;对于全球变化诱发的灾害,则力求基于科学认识与预测,在海岸带开发中合理规划建设,做到未雨绸缪,实现海岸带社会经济可持续发展。 相似文献

This paper defines the various levels within government, the voluntary agencies and the community which might benefit from training and makes suggestions as to where the emphasis should be placed. It points out that training programmes should be designed to meet the expressed needs of a particular group of trainees as well as be related to the current or potential disaster situation. 相似文献

中国东部沿海省市风暴潮经济损失风险区划 总被引:2,自引:0,他引:2
风暴潮是我国沿海省市面临的重大自然灾害之一,给这些地区造成了难以估量的损失。选取1989-2008年沿海11省、市、自治区风暴潮的历史数据作为研究样本,运用因子得分基础上的聚类分析和熵值评价等方法,对这些地区风暴潮灾害经济损失的风险进行了评估,最终按风暴潮灾害的经济损失程度将沿海省市划分为3个区域:即上海为第1区,表示风暴潮经济损失风险最小;海南、福建、浙江、广东4省为第3区,风险最大;其他省、市、自治区为第2区,表示经济损失风险居中。3个区域的灾害区划,为我们从更深层次上认识风暴潮的发生及是造成的损失情况提供了新的视角。 相似文献

当今社会面临的日趋严重且类型众多的灾害,构成了对生态环境安全的巨大威胁,为此各国都在致力于发挥法制手段在灾害防治中的不可替代的作用。我国是个多灾国家,在减灾法治方面虽已取得了一定成就,但总体上还比较薄弱,因此进一步加强该领域的法制建设十分重要。从我国环境安全保障角度及与国际经验的比较来看,完善我国减灾法制建设的基本工作涉及到减灾法制体系的理论研究、立法模式的选择及其充实方向、行政体制的理顺及执法司法功能的强化等多个方面。 相似文献

ABSTRACTThe Longmen Shan fault area in southwest China is one of the world’s most active earthquake zones. The epicenters of the two most recent earthquakes, the 2008 Wenchuan earthquake (8.0?Ms) and the 2013 Lushan earthquake (7.0?Ms), both of which caused serious losses, were only 85?km apart. Community-based disaster risk reduction is the foundation of the disaster management system pyramid and is critical to the success of ‘sustainable hazard mitigation’. Based on multiple collaborative stakeholder perspectives, this paper examines public participation in an NGO-oriented Community for Disaster Prevention and Mitigation (N-CDPM) in the period between the two earthquakes as a multi-stage problem; N-CDPM establishment, normal operations, disaster testing, and continuous improvement. Multi-stage field research was conducted in the affected areas in the Longmen Shan fault area to examine the collaboration in each stage, after which the differences were compared across the four stages based on eight key indices; scales, core stakeholders, core network stability, mean number of lines, mean collaborative level, governments, and individual and public organization participation. The government participation, individual participation, and public organization participation are then discussed. This paper provides a novel research approach to CDPM in multiple earthquake regions and gives rich insights into the collaboration between the government and the public for N-CDPM. 相似文献

The tsunami that struck the coasts of India on 26 December 2004 resulted in the large‐scale destruction of fisher habitations. The post‐tsunami rehabilitation effort in Tamil Nadu was directed towards relocating fisher settlements in the interior. This paper discusses the outcomes of a study on the social effects of relocation in a sample of nine communities along the Coromandel Coast. It concludes that, although the participation of fishing communities in house design and in allocation procedures has been limited, many fisher households are satisfied with the quality of the facilities. The distance of the new settlements to the shore, however, is regarded as an impediment to engaging in the fishing profession, and many fishers are actually moving back to their old locations. This raises questions as to the direction of coastal zone policy in India, as well as to the weight accorded to safety (and other coastal development interests) vis‐à‐vis the livelihood needs of fishers. 相似文献
