1990年以来中国海洋灾害系统风险特征分析及其综合风险管理

长期以来,海洋灾害一直是困扰着海域及海岸带社会经济发展的一大障碍.中国是深受海洋灾害影响的国家之一.为此,从灾害系统论的角度,分析了1990年以来中国海洋灾害系统的风险特征.研究表明,中国在过去的15年中,工程性防灾减灾措施已经使海洋灾害灾情得到了一定的控制,但由于中国海域海事活动不断增多、海岸带经济密度快速提高,大大增加了海域及海岸带承灾体对海洋灾害风险的暴露,又由于海岸带及近海海域污染加重,海洋生物灾害发生的可能性增大,使中国海域面临的灾害风险趋于上升.此外,还讨论了中国海洋灾害综合风险管理的体系,提出从海洋灾害系统角度,加强海洋灾害综合风险管理能力的建设,以促进海洋及海岸带地区由政府、企业、社区共同组成的综合减灾范式的建立.     

中国城市综合灾害风险管理现状与对策

世界性城市灾害的加剧已成为城市化进程中的一大障碍，它也是城市化过程的产物。如何协调城市化过程与城市综合灾害风险管理，已成为当今世界、特别是像中国这样的发展中国家可持续发展的一大难题。在综述了中国城市灾害及其风险管理现状的基础上，通过对其薄弱环节的综合分析，依据作者提出的综合灾害风险管理模式，就中国城市综合灾害风险管理对策提出了3条政策建议：即完善城市灾害风险管理的信息保障机制，特别是灾害预警体系、信息共享体系和信息公开机制；加强城市综合减灾能力的建设，特别是明确城市建设中减灾工程与非工程设施投入的固定比例，完善减灾教育宣传体系和综合灾害应急响应的科技平台体系；建立城市综合灾害风险管理范式，特别是高度重视城市规划中综合减灾规划的改进和完善，加快拓展城市企业灾害保险与再保险和发展适应城市灾害风险的“安全社区”范式。     

综合自然灾害风险管理--全面整合的模式与中国的战略选择

综合自然灾害风险管理是目前国际上防灾减灾和灾害管理较先进的措施和模式，是针对各种自然灾害的全灾害的管理，是贯穿于灾害管理全过程，集中于灾害风险和承灾体脆弱性分析并强调多层面、多元化和多学科参与合作的全面整合的灾害管理模式。介绍了综合自然灾害风险管理的必要性、概念和本质，探讨了综合自然灾害管理的基本理论、对策及其实施过程和实施战略，在此基础上提出了对我国实施综合自然灾害风险管理的建议，为强化和推动我国综合自然灾害风险管理提供参考。     

自然灾害软风险区划图模式研究

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 The past basis for legitimacy is no longer valid, but tomorrow's social contract is not yet defined.     

Strengthening the role of science and technology in disaster risk reduction: the Chilean strategy

This paper presents an integrative case study of Chile's national strategy of research, development, and innovation (R&D+i) for disaster resilience and progress towards developing the institutional conditions necessary for its successful implementation. The paper covers the period between 2016 and 2021, concentrating on the work of the Chilean Commission of R&D+i for Resilience to Disasters of Natural Origin (CREDEN). Through an analysis of the official records of the initiative at all of its stages, and 29 semi-structured interviews with CREDEN members and stakeholders, we aim to present a successful example of strengthening the role of science and technology in disaster risk reduction. Chile's experience is particularly interesting because its strategy focused on R&D+i and proposed developing an industry of scientific-based technological solutions for disaster resilience. The study also illustrates how strategic interaction between academia, state, and industry can be a key factor in aligning knowledge production to tackle current socio-technical challenges.     

Taking stock of community-based flood risk management in Malawi: different stakeholders,different perspectives

Current flood risk strategies in Malawi are characterized by community-based flood risk management (CB-FRM), even though studies explicitly documenting evidence of successful CB-FRM remain limited. This paper investigates the realities and challenges of CB-FRM as seen through a lens of different stakeholders. In order to capture the experiences of CB-FRM, a predominantly qualitative research framework was developed. In 2016, 11 focus group discussions with stakeholder groups (local communities, local government and non-governmental organisations) were held. Additionally, informal discussions, field visits, a short survey and an extensive desk study were undertaken. The findings were analysed according to the major themes that emerged related to the realities and challenges of specific stakeholder groups. Although response and relief still remain prominent components of CB-FRM in Malawi, a number of mitigation and preparedness activities is observed. However, a lack of in-country resources, relief-oriented aid approaches and an ‘aid dependency’ syndrome represent obstacles. Different stakeholder groups share similar challenges in terms of financing, participation, decentralised governance and project management. Lack of project sustainability and localised ownership also emerged as major challenges. The identified challenges shed light on the frontiers and directions in which improvements are needed, thus offering a valuable contribution to the existing knowledgebase.     

Nutrition, Disease and Death in Times of Famine

In this article we review the relationship between malnutrition and mortality, and the interaction of morbidity, with the aim of clarifying the health risks of malnutrition in situations of famine and food insecurity. Apart from reviewing what is known about this relationship, we highlight areas where further research is needed. Among refugee and famine affected populations living in camps, there appears to be a close association between high rates of malnutrition and excess mortality. Results from communitybased prospective studies of malnutrition and mortality among individuals conclude that as nutritional status declines the risk of death increases, although the discriminating power of different nutritional indices and the strength of the association varies considerably in different locations and at different times. These differences are attributed mainly to the different prevailing patterns of morbidity and growth failure, which are influenced by both environmental and social factors. In situations of famine and population displacement, the deterioration in the health environment increases exposure to infection and is likely to raise the threshold of nutritional status which corresponds to an increased risk of mortality. This has important implications for nutritional assessments and interventions.     

Financing climate change adaptation

This paper examines the topic of financing adaptation in future climate change policies. A major question is whether adaptation in developing countries should be financed under the 1992 United Nations Framework Convention on Climate Change (UNFCCC), or whether funding should come from other sources. We present an overview of financial resources and propose the employment of a two-track approach: one track that attempts to secure climate change adaptation funding under the UNFCCC; and a second track that improves mainstreaming of climate risk management in development efforts. Developed countries would need to demonstrate much greater commitment to the funding of adaptation measures if the UNFCCC were to cover a substantial part of the costs. The mainstreaming of climate change adaptation could follow a risk management path, particularly in relation to disaster risk reduction. 'Climate-proofing' of development projects that currently do not consider climate and weather risks could improve their sustainability.     

五论灾害系统研究的理论与实践

作者曾分别于1991、1996、2002和2005年发表了关于灾害研究理论与实践的4篇文章,对灾害系统的性质、动力学机制、综合减灾范式,以及灾害科学体系等进行了探讨.在前4篇文章的基础上,就当前国际上灾害风险综合研究的趋势、应对巨灾行动,以及防范巨灾风险和加强综合减灾学科建设等方面进行了综合分析,阐述了对"区域灾害系统"作为"社会-生态系统"、"人地关系地域系统"和"可划分类型与多级区划体系"本质的认识;区分了"多灾种叠加"与"灾害链"损失评估的差异;论证了"综合灾害风险防范的结构、功能,及结构与功能优化模式";构建了由灾害科学、应急技术和风险管理共同组成的"灾害风险科学"学科体系.研究结果表明,通过综合减灾,防范巨灾风险已成为区域和全球可持续发展的重要措施,这一措施与资源节约型与环境友好型社会的建设,循环经济模式的发展,以及低碳经济模式的建立,共同构成了可持续发展战略实施的支撑体系.

介绍了于2006年8月28日至9月1日在瑞士达沃斯举行的国际减灾会议的主要内容。在阅读本次会议有关论文扩展摘要集内容。以及会议上散发的大量文件、研究报告的基础上,综述了当前国际减灾研究与实践工作中,学术界、政界与企业界等在探索协调发展与减灾进程中的主要进展和发展趋向。国际减灾界当前关注的主要领域为：建立灾害与风险科学,善待与重建生态系统,关注全球环境变化与灾害的密切关系,重视利用金融、保险和再保险手段转移风险,关注女性在灾害风险管理中的作用,关注恐怖主义对社会风险的强化作用,发展灾害风险管理的信息支撑平台,重视建设高风险地区综合减灾范式。在此基础上,针对中国可持续发展战略实施过程中存在的主要问题,提出中国协调发展与减灾对策为：建立国家协调发展与减轻灾害风险的管理体制与运行机制,加强控制综合灾害风险水平的生态系统等减灾基础设施建设,发挥女性在农村地区综合灾害风险管理中的作用,建立区域综合灾害风险管理与减灾范式和加强区域综合灾害风险防范关键技术的开发,促进灾害与风险学科体系的形成。     

Engaging pet owners in disaster risk and preparedness communications: simplifying complex human–animal relations with archetypes

The influence of human–animal relationships upon owners' perceptions and behaviours can lead to situations that place owners and animals at risk of harm. Pet ownership particularly is considered a risk factor for unsafe responses to natural hazards, though conversely, it can also be viewed as a protective factor that motivates disaster preparedness. However, each relationship should not be treated equivalently, as characteristics considered most meaningful within them differ across various types of pet–owner relationship and along multiple dimensions. A one-size-fits-all approach to applying the pets-as-protective-factor principle is then too broad in scope. This review outlines a novel psychographic profiling approach for archetypes of pet–owner relationship characteristics as a means of describing risk-preparedness foci and risk propensities within disaster contexts. Understanding those differences as detailed archetypes can help emergency services more effectively target pet owners through reframing disaster risk and preparedness communications in relation to prominent characteristics of relationship archetypes. We argue that this approach can improve the effectiveness of risk and preparedness communications by increasing pet owners' receptivity to, and cognitive involvement with, message content.     

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.     

基于格网GIS的豫北地区干旱灾害风险区划

以豫北地区32个市县为研究区域,从造成干旱灾害的4个因子,即致灾因子危险性、承灾体暴露性、脆弱性和防灾减灾能力4个角度出发,选取了包括气象、土壤、人口、社会经济在内的17项指标,在格网GIS技术的支持下,对评价体系中的各指标进行10 km×10 km尺度的网格化表达。应用自然灾害风险指数法,熵组合权重法和加权综合分析法,建立了干旱灾害风险评价模型;通过选取典型案例年,运用最优分割理论确定了干旱灾害风险阈值,并利用GIS技术绘制了豫北地区的干旱灾害风险区划图。结果显示:豫北地区的高风险区主要集中在濮阳市区、濮阳县、清丰县、南乐县、新乡市区;而西部的济源市、孟州市,以及原阳县风险较轻。

Minimization of socioeconomic disruption for displaced populations following disasters

In the aftermath of catastrophic natural disasters such as hurricanes, tsunamis and earthquakes, emergency management agencies come under intense pressure to provide temporary housing to address the large‐scale displacement of the vulnerable population. Temporary housing is essential to enable displaced families to reestablish their normal daily activities until permanent housing solutions can be provided. Temporary housing decisions, however, have often been criticized for their failure to fulfil the socioeconomic needs of the displaced families within acceptable budgets. This paper presents the development of (1) socioeconomic disruption metrics that are capable of quantifying the socioeconomic impacts of temporary housing decisions on displaced populations; and (2) a robust multi‐objective optimization model for temporary housing that is capable of simultaneously minimizing socioeconomic disruptions and public expenditures in an effective and efficient manner. A large‐scale application example is optimized to illustrate the use of the model and demonstrate its capabilities ingenerating optimal plans for realistic temporary housing problems.     

Revisiting community-based disaster risk management

This paper examines whether the hypothesis presented in Ocho Rios in 1984 is still valid and relevant. The first part of the paper revisits the central tenets of the 1984 paper. The second part of the paper gives a broad overview of how community-based approaches have been taken up and evolved over the last quarter-century. The third part of the paper examines, with the benefit of hindsight, to what extent the approaches advocated in Ocho Rios are still valid. Finally, the paper examines the role of community-based and local-level approaches looking into the future. The paper is written as a personal reflection, without any pretence to academic rigour and also without systematically surveying the thousands of ongoing community-based or local-level initiatives in disaster risk management, referred to in this paper as community-based disaster risk management and local-level disaster risk management, respectively.     

Re-framing risk: the changing context of disaster mitigation and preparedness

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.
