A proposed framework of key activities and processes in the preparedness and recovery phases of disaster management

This paper proposes an empirically grounded framework for examining the preparedness and recovery phases of disaster management activities and processes pertaining to predictable disasters within a developed country. The two‐stage framework provides a single model composed of important preparedness and recovery initiatives, as well as activities and processes derived from empirical data collected for case studies from Australia: the ‘Black Saturday’ bushfires in the state of Victoria in February 2009; and Cyclone Larry in March 2006. The framework enables a variety of analyses, including the generation of insights into disaster management preparedness and recovery in the context of events in wealthy developed countries. The paper combines two empirical examples, a series of bushfires and a severe tropical cyclone, to enhance understanding of, and to contribute to better, disaster preparedness and recovery in the future. The paper contributes to the growing literature on disasters, preparedness, recovery and associated logistics, and other issues.     

From disaster to development: a systematic review of community‐driven humanitarian logistics

A plethora of untapped resources exist within disaster‐affected communities that can be used to address relief and development concerns. A systematic review of the literature relating to community participation in humanitarian logistics activities revealed that communities are able to form ad hoc networks that have the ability to meet a wide range of disaster management needs. These structures, characterised as Collaborative Aid Networks (CANs), have demonstrated efficient logistical capabilities exclusive of humanitarian organisations. This study proposes that CANs, as a result of their unique characteristics, present alternatives to established humanitarian approaches to logistics, while also mitigating the challenges commonly faced by traditional humanitarian organisations. Furthermore, CANs offer a more holistic, long‐term approach to disaster management, owing to their impact on development through their involvement in humanitarian logistics. This research provides the foundation for further theoretical analysis of effective and efficient disaster management, and details opportunities for policy and practice.     

Spatial and temporal analysis of natural hazard mortality in Nepal

The impacts of natural hazards are typically measured in terms of loss of human lives and economic damage, and recent studies demonstrate that deaths attributed to natural hazards have increased. Using the publicly available DesInventar database, we examined spatial and temporal patterns of natural hazard mortality from 1971 to 2011 at the district and village levels of Nepal and identified natural hazards that contributed most to mortality. Spatial clusters of mortality at the district and village levels were detected using local and global spatial autocorrelation measures (Moran's I). Landslides (41.91%) and floods (32.52%) accounted for approximately three quarters of natural hazard mortalities over the study period. A Global Moran's I test positively confirmed clustering at both the district (0.199, p?p?相似文献   

Types of community-focused organisations for disaster risk reduction in the Longmen Shan Fault area

In the past 10 years, both the Wenchuan earthquake (2008, Magnitude?=?8.0) and the Lushan earthquake (2013, Magnitude?=?7.0) struck in the Longmen Shan Fault area, causing extraordinary human and economic losses. After the Wenchuan earthquake, the Chinese government began promoting the Community for Disaster Prevention and Mitigation (CDPM) project nationwide to enhance community-level disaster-resistance capacities. Due to post-earthquake demand, CDPM construction in the Longmen Shan Fault area involved many diverse organisations, each of which had different organisational leadership models, which greatly influenced the CDPM characteristics and mechanisms. From long-term field research in 23 CDPM organisations in Longmen Shan Fault area, four types of CDPM organisations were found, including eight Government-oriented CDPM, six Resident-oriented CDPM, seven NGO-oriented CDPM and two Enterprise-oriented CDPM, forming a multiple organisation-oriented CDPM (M-CDPM) model. As there was only 85?km between the Wenchuan earthquake and the Lushan earthquake epicentres, many of the hardest-hit regions were the same; therefore, most CDPM organisations examined in this study were established after the Wenchuan earthquake and their effectiveness was tested in the Lushan earthquake. Therefore, research on the M-CDPM gives valuable information and provides a practical perspective for community-level disaster risk reduction.     

“一带一路”所经陆路地域巨震链特征研究

针对“一带一路”的陆路部分（即古丝绸之路）所经区域的自然灾害及灾害链的问题进行了研究讨论,尤其是针对大地震及相应的灾害链。穿越陆上丝绸之路的40度纬线地带是一个主要的地震活动带。沿着它易呈现震中定向迁移和在不长的时间内大地震发生的遥相关。陆上丝绸之路的灾害链主要是旱－震链,高山峰指标与大震发生的位置有较高的相关性。这些问题的研究对丝绸之路所经地带的安全都是有意义,也对丝绸之路上国家的安全合作有学术指向的意义。     

19世纪末以来中国洪涝灾害变化及影响因素研究

基于1880年以来全国洪灾灾情、耕地面积以及东部地区年降水量数据,采用EMD分解、MK趋势和突变检验与相关分析等方法,探讨19世纪末至21世纪初中国洪涝灾害的变化特征,及其与降水变化和人类活动之间的联系。结果表明:①19世纪末、20世纪50-60年代和20世纪末这3个时间段,是多世纪以来中国洪灾最剧烈的时期;其中19世纪末和20世纪50-60年代的洪灾剧烈期均对应降水丰沛期,而20世纪末的洪灾剧烈期降水并不十分丰沛。②中国洪灾存在多尺度特征,主要周期有2.7 a、5.2 a的年际变化、9.9 a的年代际和20.5 a、51.6 a的几十年际变化等;东部地区年降水量与洪灾变化周期对应关系较好。③从东部近50 a来年降水量变化来看,20世纪八九十年代洪灾上升并不是降水量增加的结果。降水强度增加、极值降水事件增多可能是其重要原因;另一方面则是由于水土流失加剧、湖泊围垦等人类活动因素的影响。此外,水利投资强度的变化对近50 a洪灾变化也有一定影响。

区域洪涝灾害恢复力时空演变研究——以巢湖流域为例

提高自然灾害恢复力是应对气候变化和自然灾害的重要途径之一。在总结自然灾害恢复力研究的基础上,全面考虑自然、社会、经济、技术、管理等5个维度对其的影响,构建巢湖流域洪涝灾害恢复力评价指标体系,并基于ANP分析方法求得非独立指标间的权重,评价巢湖流域洪涝灾害恢复力,进而分析2000~2010年之间巢湖流域洪涝灾害恢复力时空演变规律,以期为提高巢湖流域洪涝灾害恢复力水平提供有价值的参考。研究结果表明,2000~2010年巢湖流域大部分地区洪涝灾害恢复力指数都在增长,但增长速率存在不同地区、不同维度上的明显差异;从流域平均水平来看,10 a间巢湖流域洪涝灾害恢复力指数在增长,其中自然维的指数是下降的,其他维度的指数为增长,并且对巢湖流域洪涝灾害恢复力增长正向影响最大的是经济维影响因子,而自然维的影响因子对恢复力增长起到了负向作用;2000~2010年巢湖流域洪涝灾害各等级恢复力分布格局变化不大,但其他地区与合肥市辖区恢复力的差距在拉大。     

Patterns of preference and practice: bridging actors in wildfire response networks in the American Northwest

The roles of bridging actors in emergency response networks can be important to disaster response outcomes. This paper is based on an evaluation of wildfire preparedness and response networks in 21 large‐scale wildfire events in the wildland—urban interface near national forests in the American Northwest. The study investigated how key individuals in responder networks anticipated seeking out specific people in perceived bridging roles prior to the occurrence of wildfires, and then captured who in fact assumed these roles during actual large‐scale events. It examines two plausible, but contradictory, bodies of theory—similarity and dissimilarity—that suggest who people might seek out as bridgers and who they would really go to during a disaster. Roughly one‐half of all pre‐fire nominations were consistent with similarity. Yet, while similarity is a reliable indicator of how people expect to organise, it does not hold up for how they organise during the real incident.     

The evolving local social contract for managing climate and disaster risk in Vietnam

How do disasters shape local government legitimacy in relation to managing climate‐ and disaster‐related risks? This paper looks at how local authorities in Central Vietnam perceive their social contract for risk reduction, including the partial merging of responsibilities for disaster risk management with new plans for and investments in climate change adaptation and broader socioeconomic development. The findings indicate that extreme floods and storms constitute critical junctures that stimulate genuine institutional change. Local officials are proud of their strengthened role in disaster response and they are eager to boost investment in infrastructure. They have struggled to reinforce their legitimacy among their constituents, but given the shifting roles of the state, private sector, and civil society, and the undiminished emphasis on high‐risk development models, their responsibilities for responding to emerging climate change scenarios are increasingly nebulous. The past basis for legitimacy is no longer valid, but tomorrow's social contract is not yet defined.
