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.     

Probabilistic cost‐benefit analysis of disaster risk management in a development context

Limited studies have shown that disaster risk management (DRM) can be cost‐efficient in a development context. Cost–benefit analysis (CBA) is an evaluation tool to analyse economic efficiency. This research introduces quantitative, stochastic CBA frameworks and applies them in case studies of flood and drought risk reduction in India and Pakistan, while also incorporating projected climate change impacts. DRM interventions are shown to be economically efficient, with integrated approaches more cost‐effective and robust than singular interventions. The paper highlights that CBA can be a useful tool if certain issues are considered properly, including: complexities in estimating risk; data dependency of results; negative effects of interventions; and distributional aspects. The design and process of CBA must take into account specific objectives, available information, resources, and the perceptions and needs of stakeholders as transparently as possible. Intervention design and uncertainties should be qualified through dialogue, indicating that process is as important as numerical results.

Reducing disaster risks 1980–2010: Some reflections and speculations

Through personal reflections on themes covering past experiences, the author considers selected experiences of disaster risk management (DRM) that span 30 years of DRM, and makes some speculations concerning the future, and ponders whether within the selected themes the future looks positive or negative. The observations begin with some memories of the Ocho Rios Conference: a multi disciplinary expedition to examine housing and hazards in Pakistan; issues concerning education and training; and finally the success of a massive reconstruction project of rural dwellings in Pakistan following the 2005 earthquake. Some key questions are considered: the value of community-based risk management; the reduction of short- or long-term risks; the protection of critical facilities; whose reality is being addressed? official neglect of education for DRM; the conditions needed to create highly effective safe reconstruction in rural Pakistan.     

Household self‐blame for disasters: responsibilisation and (un)accountability in decentralised participatory risk governance

The most important theoretical argument concerning decentralised participatory governance is that it can make a government more accountable for the needs of the governed. Key to this process are participatory spaces that act as mechanisms for dialogue between citizens and local government. However, within Cochabamba, a city in the centre of Bolivia, South America, ‘at‐risk’ citizens engage minimally with disaster risk issues in participatory spaces, despite high levels of civic participation. This is because ‘at‐risk’ populations view disasters as a private/household problem that is symptomatic of household error, rather than seeing them as a broader public problem due to wider structural inequalities. Consequently, they redistribute responsibility for disaster risk reduction towards households, which (re)produces the absolution of government authorities as guarantors of disaster risk reduction. This paper challenges the normative assumption that participatory spaces facilitate democratic deliberation of disaster risk reduction and the downward accountability of local government for disaster risk reduction.

Developing indicators to measure post‐disaster community recovery in the United States

Disaster recovery is a key capability of federal, state, and local government. To support this capability effectively practitioners need useful and validated metrics to document how well a community is recovering from a particular disaster. This study developed and categorised recovery indicators according to the Federal Emergency Management Agency (FEMA)'s Recovery Support Functions and Recovery Mission Area Core Capabilities through a literature review, an evaluation of the pre‐disaster recovery plans for 87 coastal jurisdictions, and a case study of two communities (New Hanover County, North Carolina, and the City of Hoboken, New Jersey). Metrics identified in the literature were validated through the recovery plan review and the case study. The research team also identified sources for both baseline and current status data. Based on these findings, a user‐friendly checklist for practitioners was established, which will be piloted with practice partners during a future disaster recovery initiative.     

Progress in natural hazard risk reduction: What hath development wrought?

The development-disaster risk management agenda has been shaped over the last 25 years by development policies and practices that have isolated lesser developed countries' development agenda from dealing with risk to natural hazards, by intentional actions to create a theory and practice of disaster risk management alongside other cross-cutting issues, by attempting to nurture emergency management in the context of disaster risk management and by fostering competition for resources. Sovereign states, multilateral development banks and the international development community should collaborate in shifting paradigms to: consider all development actions as initiatives to reduce risk; separate emergency management policy and practice from disaster risk management; fold disaster risk management and climate change adaptation into development planning and lending processes so as to address risk to natural hazards; promote hazard, vulnerability and risk information as a public good; and insist on accountability and responsibility to natural hazard risk all along the development continuum.     

Disaster risk, climate change and international development: scope for, and challenges to, integration

Reducing losses to weather-related disasters, meeting the Millennium Development Goals and wider human development objectives, and implementing a successful response to climate change are aims that can only be accomplished if they are undertaken in an integrated manner. Currently, policy responses to address each of these independently may be redundant or, at worst, conflicting. We believe that this conflict can be attributed primarily to a lack of interaction and institutional overlap among the three communities of practice. Differences in language, method and political relevance may also contribute to the intellectual divide. Thus, this paper seeks to review the theoretical and policy linkages among disaster risk reduction, climate change and development. It finds that not only does action within one realm affect capacity for action in the others, but also that there is much that can be learnt and shared between realms in order to ensure a move towards a path of integrated and more sustainable development.

Vested Interest theory and disaster preparedness

Three studies were designed to extend a combination of vested interest theory (VI) and the extended parallel process model of fear appeals (EPPM) to provide formative research for creating more effective disaster preparedness social action campaigns. The aim was to develop an effective VI scale for assessing individual awareness and ‘vestedness’ relevant to disaster preparedness. Typical preparedness behaviours are discussed with emphasis on earthquakes and tornados in particular. Brief overviews of VI and the EPPM are offered, and findings are presented from three studies (one dealing with earthquakes, and two with tornados) conducted to determine the factor structure of the key VI components involved, and to develop and test subscales derived from the two theories. The paper finishes with a discussion of future research needs and suggestions on how the new subscales may be applied in the design and execution of more effective disaster preparedness campaigns.

Beyond the community: integrating local and scientific knowledge in the formal development approval process in Jamaica

Community-based disaster risk management methods routinely include capture of local knowledge which is used to inform community-level risk reduction programmes and development plans. In Jamaica, development planning at the national level has relied historically on scientific knowledge, usually to the exclusion of local knowledge. However, community disaster risk management plans reviewed for this paper show that communities have very clear ideas on the threat posed by hazards, resources at risk from the hazards and ways of reducing the risk. Communities also appreciate the value of cultural and historical sites and are willing to sacrifice development in order to protect and preserve these sites. Such knowledge is valuable for informing risk-sensitive development planning, and should be captured within the formal development approval system. A model is proposed in which community and scientific knowledge can be integrated into the formal development approval process at the national level. The model includes integrating community representatives in technical committee reviews, capturing local knowledge through community consultations and subjecting community knowledge to validation prior to its use. Successful implementation of this model should result in more accurate field assessments for risk-sensitive development planning as local knowledge provides current, site-specific information. Better risk-sensitive development planning will ultimately lead to reduced exposure to hazards and reduction in losses from the impact of hazards for Jamaica.     

Recovery after disaster: achieving sustainable development, mitigation and equity

This paper reviews key findings and raises issues that are not fully addressed by the predominant disaster recovery literature. Achievement of equity, mitigation and sustainable development, particularly through local participation in redevelopment planning and institutional cooperation, is the central issue of the review. Previous research and past assumptions about the process by which communities rebuild after a disaster are reviewed. A conceptual model for understanding local disaster recovery efforts is then presented. The conceptual and practical significance of this model is then demonstrated by presenting case studies of local recovery experiences. Finally, conclusions on the current understanding of disaster redevelopment planning, as well as implications for public policy and future research are offered.     

Academic publishing in disaster risk reduction: past,present, and future

Nowadays there are approximately 80 Anglophone journals that deal primarily with disaster risk reduction (DRR) and allied fields. This large array signals a sustained, if uneven, growth in DRR scholarship but also competition between the offerings of different publishers and institutions. The purpose of this article is first to summarise the development of academic publishing on DRR from its early beginnings to the present day. The paper then evaluates the current state of publishing in this field and discusses possible future trends. Next, it identifies some possible opportunities, challenges, expectations, and commitments for journal editors both within DRR and academia more broadly, including those that refer to changes in the use of terminology, the relentless increase in the number of papers submitted, the expansion and dangers of predatory journals, different peer review models, open access versus paywalls, citations and bibliography metrics, academic social networks, and copyright and distribution issues.

A review of coastal community vulnerabilities toward resilience benefits from disaster reduction measures

The coast has always been an area of significant hazards. In situations of community self-sufficiency, consequences of coastal hazards might be isolated to regions directly affected by the hazard. But, in the current global economy, fewer and fewer communities are isolated; damage to one location frequently has consequences around the globe and coastal community resilience can have broad-reaching benefits. Hazard responses for the built coastal environment have typically been resistance: constructing stronger buildings, enhancing natural barriers or creating artificial barriers. These approaches to hazard reduction through coastal engineering and shoreline defence efforts have been crucial to sustained coastal development. However, as coastal forces continue or magnify and resources become scarcer, resistance alone may be less effective or even unsustainable, and interest in resilience has grown. Resilience is a community's ability either to absorb destructive forces without loss of service or function, or to recover quickly from disasters. Community resilience encompasses multiple elements, ranging from governance to structural design, risk knowledge, prevention, warning systems and recovery. This paper focuses on hazards of coastal communities, and provides a review of some recent engineering efforts to improve the resilience elements of risk knowledge and disaster warnings for coastal disaster reduction.     

我国主要农业气象灾害机理与监测研究进展

对我国农业气象灾害机理与监测方面的研究进行了深入系统的回顾与评述,阐述了我国主要农业灾害研究的前沿领域和学术问题,探讨了农业灾害研究的发展趋势.灾害性天气只是农业成灾的外部环境条件(环境胁迫),在这种环境胁迫下,农业生产系统是否最终成灾,还要取决于农业生产系统本身对这种环境胁迫的应对和作用.因此农业灾害机理反映了环境胁迫与农业生产系统的相互作用和相互影响.当前,对农业灾害机理研究不足,农业成灾过程和关键因子认识不深入,农业灾害监测理论与方法不完善,已经成为建立有效的农业灾害监测预警系统、开展灾害时空动态监测,以及国家进行重大防灾减灾决策的瓶颈和障碍.对主要农业灾害机理开展研究以及发展农业灾害理论和监测方法,是国家实现农业发展目标的需要,也是多门相关学科理论与方法发展的需要.
