城市建筑物抗震能力评估方法

由于建筑物震害预测方法只能估计建筑物的破坏而不能评定建筑物的抗震能力,基于对城市建筑物潜在破坏的估计,提出了城市建筑物抗震能力的评估方法。影响城市建筑物抗震能力的因素包括城市所处的地震危险性环境和城市建筑物的易损性。为了考虑地震危险性因素,进行了以地面峰值加速度(PGA)为参数的地震危险性分析,提出了我国不同地震危险性特征分区的PGA概率密度函数;为了考虑建筑物的易损性因素,采用HAZUS-MH中的静力弹塑性分析(push-over anal-ysis)方法研究群体建筑物易损性。通过对这两个因素的研究,建立了城市建筑物抗震能力评估方法,提出的相对全概率抗震能力指数可以反映城市建筑物在其所在的地震危险性环境下所具有的抗震能力,而采用绝对全概率抗震能力指数能够比较不同建筑抗震能力的差异,再结合建筑物抗震能力评估标准,可确定抗震能力水平。以晋江市抽样建筑物抗震能力评估为例,结合震害经验,论证了该方法的有效性。

East Timor emerging from conflict: the role of local NGOs and international assistance

International assistance efforts have represented a conundrum for East Timorese seeking to assert their new independence and autonomy. While urgent needs have been met, local participation, involvement and capacity building have not been given adequate attention. This outcome is aptly demonstrated in the case of local non-government organisations (LNGOs). This paper specifically examines the role of LNGOs in the recovery of East Timor within the international assistance programme. It examines the challenges of rehabilitation efforts in East Timor with a particular focus on capacity building of East Timorese NGOs as part of a broader effort to strengthen civil society. The initial crisis response in East Timor highlighted tension between meeting immediate needs while simultaneously incorporating civil society actors such as NGOs and communities. It has been argued that local NGOs and the community at large were not sufficiently incorporated into the process. While it is acknowledged that many local NGOs had limited capacity to respond, a greater emphasis on collaboration, inclusion and capacity building was desirable, with a view to supporting medium and longer term objectives that promote a vibrant civil society, sustainability and self-management.

Investigating the strategic antecedents of agility in humanitarian logistics

This study investigates the strategic antecedents of operational agility in humanitarian logistics. It began by identifying the particular actions to be taken at the strategic level of a humanitarian organisation to support field‐level agility. Next, quantitative data (n=59) were collected on four strategic‐level capabilities (being purposeful, action‐focused, collaborative, and learning‐oriented) and on operational agility (field responsiveness and flexibility). Using a quantitative analysis, the study tested the relationship between organisational capacity building and operational agility and found that the four strategic‐level capabilities are fundamental building blocks of agility. Collectively they account for 52 per cent of the ability of humanitarian logisticians to deal with ongoing changes and disruptions in the field. This study emphasises the need for researchers and practitioners to embrace a broader perspective of agility in humanitarian logistics. In addition, it highlights the inherently strategic nature of agility, the development of which involves focusing simultaneously on multiple drivers.     

Complementing institutional with localised strategies for climate change adaptation: a South-North comparison

Climate change and disasters pose a serious risk to sustainable development. In the South, local coping strategies are an important element of adaptation to climate and disaster risk. Such strategies have emerged because of the limited assistance provided by urban actors and associated social security and governance systems. In the North, in contrast, local coping strategies are comparatively poorly developed. However, the extent of the changing climatic conditions is also reducing the capacity of Northern institutions to deal with climatic extremes and variability, which emphasises the need for more local-level engagement in the North. This paper analyses the differences in local and institutional responses to climate change and disasters in a Southern and a Northern city (San Salvador, El Salvador, and Manchester, United Kingdom, respectively), and highlights how the lessons learned might be translated into an improved distributed governance system; that is, an 'integrated engagement model', where local and institutionalised responses support rather than hinder each other, as is currently the case.

Developing Decentralized Capacity for Disaster Prevention: Lessons from Food Security and Nutrition Monitoring in Malawi

Lack of sufficient analytical capacity in most of the countries of sub-Saharan Africa has been frequently mentioned as a major factor limiting the effectiveness of drought management interventions. In this article we describe an approach used in Malawi for the past three years to develop a decentralized capacity to analyse drought management and disaster prevention programmes. A conceptual framework is presented which identifies the areas in which capacity strengthening is required and lessons from the Malawi experience are presented. Various issues relating to the efficiency of capacity building programmes are discussed. We argue that continuous dialogue between development researchers and decision-makers, and between trainers in academic institutions and donor agencies, is essential for achieving the goals of improved capacity for drought management and disaster prevention.     

Alternatives to evacuation during wildland fire: Exploring adaptive capacity in one Idaho community

The use of alternatives to evacuation during wildfire events continues to be an intensely debated strategy in the professional and policy circles of numerous fire-prone countries. The most recent chapter comes in response to the Black Saturday Fires in Australia, which has led to policy changes concerning alternatives to evacuation in both Australia and USA. This study explores the local context that influenced the development of alternatives to evacuation in one Idaho community through in-depth interviews with local residents and officials. It acknowledges alternatives as one ‘fire-adaptive behaviour’ of the local community, a key characteristic that US fire professionals identify as a means to better manage wildfire. We apply and extend a recently created adaptive capacity framework for wildfire to uncover specific community characteristics that both led to and reinforce the development of alternatives to evacuation that are tailored to the local population. Identification of these characteristics serves as one important step towards better local assessment of adaptive capacity for a broad classification of ‘fire-adaptive’ behaviours. We conclude that no one combination of local resources can guarantee the development of alternatives to evacuation. Rather, diverse local context will result in different approaches and applicability of the practice.

A 'Principled' Approach to Complex Emergencies: Testing a New Aid Delivery Model in the Nuba Mountains

This paper provides an analysis of the Nuba Mountains Programme Advancing Conflict Trans-formation (NMPACT) as an example of an operational response in a complex emergency that innovatively addressed an incipient food security crisis. NMPACT is notable for having brought together an array of actors around a common principled agenda and for being the only operational programme in the Sudan to which both warring parties subscribed during the conflict. The key features of the programme are presented and the main innovative elements are reviewed, including the role of the principles of engagement and the 'political humanitarianism' of NMPACT. The paper looks at how NMPACT broke from traditional externally driven responses to food insecurity, and, drawing on lessons from Operation Lifeline Sudan, adopted an approach that focuses on capacity building, sustainable agriculture and market revitalisation, alongside conflict transformation and peace-building. The limitations of the model are also assessed, and preliminary lessons regarding its replication in other complex emergency contexts are presented.     

Flagship regeneration project as a tool for post-disaster recovery planning: the Zeytinburnu case

Sustainable redevelopment following disasters has been a main policy objective of post-disaster recovery efforts over the past few decades. Yet, nine years after the 1999 Marmara earthquake in Turkey, the redevelopment of risky housing areas is still a point of debate on the urban planning and disaster mitigation agenda. However, planning studies on mildly and moderately damaged areas located in the centre of Istanbul are ongoing. This article presents the evidence of a pilot project undertaken by Zeytinburnu Municipality, Istanbul, four years after the Marmara earthquake. ² The aim is to generate a debate on the preconditions required for a sustainable urban regeneration approach in the post-disaster recovery phase. The results of the pilot project underline the importance of capacity building in sustaining social capital, strengthening the legal framework, restructuring planning regulations, and managing the housing redevelopment process by taking advantage of a window of opportunity afforded by the disaster recovery period.     

城市综合承灾能力与经济发展协调性研究

构成城市综合承灾能力的防灾能力、抗灾能力、救灾能力和灾后恢复能力是相互联系的。城市综合承灾能力与城市经济发展水平紧密相连。利用灰关联熵方法,分析了某城市各种承灾能力的关联性大小,以及综合承灾能力与城市经济发展水平的关联强度。但关联性强,却不能说明协调得就好。因此,又利用灰色系统理论的思想,分析了城市综合承灾能力与城市经济发展水平的协调关系,发现城市综合承灾能力对城市经济发展水平有明显的滞后性。分析得出该滞后性存在的原因后,通过对序列进行时间平移,证实了对滞后性原因的判断,并提出了加快加强城市综合承灾能力建设的建议,为后续发展奠定坚实基础。     

海河流域水环境危机和适度恢复对策的探讨

20世纪50年代以来,海河流域水资源短缺和水环境恶化问题越来越突出。河道断流,湿地萎缩,地下水大量超采,水污染和水土流失加剧,流域水环境已经恶化到十分危险的境地。回顾、总结流域水资源开发利用的历史可以清楚地看出,经济社会发展大大超过了水资源的承载能力,是海河流域水生态环境恶化的根本原因。本文认为,改善和恢复水环境,必须以供定需,以水定发展,根据流域水资源条件确定产业结构、经济规模和发展方向,努力实现人与自然的和谐相处,以水资源的可持续利用保障经济社会的可持续发展。

Effects of the tsunami on fisheries and coastal livelihood: a case study of tsunami-ravaged southern Sri Lanka

Beyond the death toll, the tsunami of 26 December 2004 crippled many of the livelihood assets (human, social, physical, financial and natural) available to assist those directly affected. Drawing on surveys of three villages in three districts in the south of Sri Lanka, this paper describes the livelihood asset building capacity of the fishing communities. Assessments are also made of the impact of the tsunami on coastal communities and the impact of government policy on rebuilding. A livelihood asset score was calculated for each village by comparing their strengths in capacity building. In all aspects of capital building, including human, social, financial, physical and natural capital, the fishing community in Tangalle was significantly ahead of the fishing communities in Hikkaduwa and Weligama. Experienced fishermen with better educational backgrounds had a significant influence on the capacity building of livelihood assets. Relocation and resettlement plans brought persistent uncertainty to fishermen in Hikkaduwa and Weligama and threatened to disrupt their community bonds and social networks.     

Using evidence to improve reproductive health quality along the Thailand-Burma border

The Mae Tao Clinic, located on the Thailand-Burma border, has provided health services for illegal migrant workers in Thailand and internally displaced people from Burma since 1989. In 2001, the clinic launched a project with the primary aim of improving reproductive health services and the secondary aim of building clinic capacity in monitoring and evaluation (M&E). This paper first presents the project's methods and key results. The team used observation of antenatal care and family-planning sessions and client exit interviews at baseline and follow-up, approximately 13 months apart, to assess performance on six elements of quality of care. Findings indicated that improving programme readiness contributed to some improvement in the quality of services, though inconsistencies in findings across the methods require further research. The paper then identifies lessons learned from introducing M&E in a resource-constrained setting. One key lesson was that a participatory approach to M&E increased people's feelings of ownership of the project and motivated staff to collect and use data for programme decision-making to improve quality.     

Understanding the causes of vulnerabilities for enhancing social-physical resilience: lessons from the Wenchuan earthquake

ABSTRACT

In an effort to understand the social-physical vulnerabilities from the 2008 Wenchuan earthquake, this research established and validated a conceptual model for natural disaster analysis. The earthquake severely impacted the built environment, with many buildings being destroyed in the earthquake and from secondary impacts. This vulnerable environment exacerbated the poverty in the local residents because of the lack of flat land and the inaccessibility of the mountainous areas. Therefore, there was an interactive relationship between the built environment vulnerability and the social vulnerability. Due to general poverty and low education levels, social vulnerability in rural areas is often the result of poor quality building construction; in the event of an earthquake, therefore, most economic losses and casualties are the result of building destruction. To enhance social-physical resilience, measures should be adopted to mitigate the vulnerability of the built environment and society through actions such as land use planning, the use of seismic-resistant technologies, and investment in infrastructure, education, industrial development, and environmental protection. This research extracts the reasons for the vulnerabilities through an examination of the interactions between the natural environment, the built environment, and the local society. The insights gained have significant theoretical and practical implications in assisting vulnerable communities resist and adapt to natural hazards to achieve sustainable development.
