Action-oriented resilience assessment of communities in Chennai,India

Building resilience to disasters is indispensable in cities, like Chennai, India, which are challenged by emerging urban disaster risks caused by impacts of urbanization and higher probability of future disasters due to climate change. In this paper, an action-oriented resilience assessment (AoRA), consisting of 63 actions, divided into 21 parameters and 5 dimensions (physical, social, economic, institutional and natural), is defined which has the objective to enhance the resilience of communities of Chennai to climate-related disasters. On the basis of responses from the selected target group, community leaders (councillors) in the 155 wards, the local government of Chennai is the key stakeholder to implement the proposed actions in the AoRA. However, further findings underpin that a multi-stakeholder approach, involving communities, academia, private organizations and NGOs, is needed to create disaster resilient communities.     

The adoption of a Climate Disaster Resilience Index in Chennai,India

Results derived from the Climate Disaster Resilience Index (CDRI)—consisting of five dimensions (economic, institutional, natural, physical, and social), 25 parameters, and 125 variables—reflect the abilities of people and institutions to respond to potential climate‐related disasters in Chennai, India. The findings of this assessment, applied in the 10 administrative zones of the city, reveal that communities living in the northern and older parts of Chennai have lower overall resilience as compared to the flourishing areas (vis‐à‐vis economic growth and population) along the urban fringes. The higher resilience of communities along the urban fringes suggests that urbanisation may not necessarily lead to a deterioration of basic urban services, such as electricity, housing, and water. This indication is confirmed by a strong statistical correlation between physical resilience and population growth in Chennai. The identification of the resilience of different urban areas of Chennai has the potential to support future planning decisions on the city's scheduled expansion.     

Local adaptation for livelihood resilience in Albay,Philippines

Local adaptation to climate change is essential for vulnerable coastal communities faced with increasing threats to livelihood and safety. This paper seeks to understand the micro-level enabling conditions for climate change adaptation through a livelihood lens in a study of six coastal villages in Bacacay in the province of Albay, Philippines. Albay is a high-risk province due to hydro-meteorological and geophysical hazards. The analysis of livelihood resilience utilizing the Sustainable Livelihoods Approach shows that a soft adaptation strategy focusing on enhancing human and social capital needs to be undertaken to increase adaptive capacity and build resilience in the study area. Moreover, the micro-level variations in the villages suggest that the understanding of local conditions is indispensable in planning and formulation of appropriate adaptation strategies and actions at local level.     

韧性理论视角下贫困村灾后恢复重建与灾害风险管理刍议

韧性理论引入灾害风险管理领域,为世界防灾减灾实践提供了新理念,并在国内外韧性城市社区建设中得到广泛应用,但针对乡村地区,尤其是高脆弱性的贫困村韧性社区建设的研究还较为鲜见。该文以韧性理论为基础,结合乡村振兴战略规划,通过对贫困村社会生态系统特征的分析,探讨了新时期我国贫困村灾后恢复重建与灾害风险管理发展方向及特点。研究发现:贫困村不仅产业经济落后,而且还具有自然环境复杂、基础设建设滞后、社会公益设施匮乏、教育水平较低、自然灾害频发等特点。这类灾害多发区与贫困人口聚集区在空间上的叠加,成为我国社会生态系统高脆弱性地区,面临着严峻的防灾减灾与扶贫开发的双重挑战;基于韧性理论视角,通过构建贫困村适灾韧性系统,开展贫困村社区韧性综合评价,调整贫困村灾后恢复重建规划编制理念等,以推动贫困村灾后恢复重建的转型;在此基础上,结合贫困村社会生态系统特点,以建立健全贫困村灾害风险管理机制、探究提升贫困村适灾韧性社区建设的新途径、协同灾害管理与乡村振兴发展目标、开展灾区恢复重建动态监测与后效评价等政策举措为抓手,深化贫困村灾害风险管理实践,提升贫困地区可持续发展能力。

Understanding and enhancing future infrastructure resiliency: a socio‐ecological approach

The resilience of any system, human or natural, centres on its capacity to adapt its structure, but not necessarily its function, to a new configuration in response to long‐term socio‐ecological change. In the long term, therefore, enhancing resilience involves more than simply improving a system's ability to resist an immediate threat or to recover to a stable past state. However, despite the prevalence of adaptive notions of resilience in academic discourse, it is apparent that infrastructure planners and policies largely continue to struggle to comprehend longer‐term system adaptation in their understanding of resilience. Instead, a short‐term, stable system (STSS) perspective on resilience is prevalent. This paper seeks to identify and problematise this perspective, presenting research based on the development of a heuristic ‘scenario–episode’ tool to address, and challenge, it in the context of United Kingdom infrastructure resilience. The aim is to help resilience practitioners to understand better the capacities of future infrastructure systems to respond to natural, malicious threats.     

基于灾后恢复过程解析的城市韧性评价体系

为实现对城市韧性的有效评价,本论文在系统研究国际城市韧性评价体系的基础之上,结合中国城市发展的现状,基于对城市灾后实际恢复过程的系统考察,建立了基于恢复过程的城市韧性评价体系。该评价体系通过解析城市灾后恢复过程的四个阶段:救援阶段(Rescue)、避难阶段(Refuge)、重建阶段(Rebuild)、复兴阶段(Revival),从社区与人口(Community and Population)、政府与管理(Official Organization and Management)、住房与设施(Valuable Housing and Facilities)、经济与发展(Economy and Development)、环境与文化(Renewable Environment and Culture)共五个维度,以62项指标对城市的韧性进行系统分析。这一体系可以简称为城市韧性评价的ReCOVER体系,其中“Re”代表了城市恢复的四个阶段,COVER则分别代表了城市韧性的五个维度。进而以该体系为基础,对我国大陆31个省级行政区域的城市韧性进行了五个维度、四个阶段的实证研究,并对城市韧性的提升策略,给出了分析建议。     

Food Security in Complex Emergencies: Enhancing Food System Resilience

This paper explores linkages between food security and crisis in different contexts, outlining the policy and institutional conditions needed to manage food security during a crisis and to rebuild the resilience of food systems in periods of relative peace. The paper reviews experiences over the past decade of countries in protracted crisis and draws lessons for national and international policy. It assesses the different alternatives on offer in fragile countries to address, for example, the disruption of institutional mechanisms and the decreasing level of support offered by international donors with respect to longer-term expectations. It proposes a Twin Track Approach to enhance food security resilience through specific policies for protracted crises that link immediate hunger relief interventions with a long-term strategy for sustainable growth. Finally, the article analyses policy options and the implications for both short- and longer-term responses vis-à-vis the three dimensions of food security: availability; access; and stability.     

Climate change as a major slow-onset hazard to development: an integrated approach to bridge the policy gap

Specific recommendations to implement this integration are introduced.     

中国自然灾害灾后响应能力评价与地域差异

灾后恢复是减灾管理的重要环节。从灾害系统角度界定了恢复性的概念；构建了由地均粮食产量、单位面积上拥有的病床床位数、人均城乡居民储蓄存款余额、地均财政收入、人均财政收入、基本建设投资和综合通行能力等指标组成的评价指标体系；提出了灾后恢复能力指数模型；对全国县域单元进行了灾后恢复能力评价。结果表明：我国灾后恢复能力指数Z值呈现“东高西低”的地域差异；贫困县域Z值普遍偏低，西藏、新疆西部、西南云贵地区、北方农牧交错带应是当前进行恢复能力建设的重点区域；城市Z值普遍较高，其地域差异与城市经济水平相对应。研究结果可为自然灾害救助区划提供依据，为减灾县域管理决策提供支持。     

Post‐Ike economic resilience along the Texas coast

The economic devastation resulting from recent natural disasters has spawned intense interest in programmes that promote regional resilience. The economic impacts of Hurricane Ike (September 2008) endured long beyond the storm's landfall, compounded by a national recession. This study analyses the pattern of post‐Ike industrial growth in eight coastal counties of Texas, United States, and identifies sources of resilience and potential drivers of recovery. The results indicate that post‐disaster growth patterns differ from established growth patterns. Levels of resilience vary across industrial sectors, and service sectors tend to lead a recovery. The resilience of the hotel and restaurant sector, for instance, suggests that the presence of relief workers might immunise certain sectors against a post‐disaster economic downturn. Besides the sectors that are generally resilient, each county has its own distinct sectors that, depending on the extent of the damage suffered, tend to perform strongly after a disaster, owing to the characteristics of the respective county's economy.     

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.     

The self‐built ecovillage in L'Aquila,Italy: community resilience as a grassroots response to environmental shock

The paper applies the community resilience approach to the post‐disaster case of Pescomaggiore, an Italian village affected by the L'Aquila earthquake in 2009. A group of residents refused to accept the housing recovery solutions proposed by the government, opting for autonomous recovery. They developed a housing project in the form of a self‐built ecovillage, characterised by earthquake‐proof buildings made of straw and wood. The project is a paradigmatic example of a community‐based response to an external shock. It illustrates the concept of ‘community resilience’, which is widely explored in the scientific debate but still vaguely defined. Based on qualitative methodologies, the paper seeks to understand how the community resilience process can be enacted in alternative social practices such as ecovillages. The goal is to see under which conditions natural disasters can be considered windows of opportunity for sustainability.

Elements of resilience after the World Trade Center disaster: reconstituting New York City's Emergency Operations Centre

In this paper we examine the reconstitution of the Emergency Operations Centre (EOC) after its destruction in the World Trade Center attack, using that event to highlight several features of resilience. The paper summarises basic EOC functions, and then presents conceptions of resilience as understood from several disciplinary perspectives, noting that work in these fields has sought to understand how a natural or social system that experiences disturbance sustains its functional processes. We observe that, although the physical EOC facility was destroyed, the organisation that had been established to manage crises in New York City continued, enabling a response that drew on the resources of New York City and neighbouring communities, states and the federal government. Availability of resources--which substituted for redundancy of personnel, equipment and space--pre-existing relationships that eased communication challenges as the emergency developed and the continuation of organisational patterns of response integration and role assignments were among the factors that contributed to resilience following the attack.     

Mapping cultural vulnerability in volcanic regions: The practical application of social volcanology at Mt Merapi,Indonesia

Protecting at-risk communities from geological hazards requires both knowledge of the physical hazard and an understanding of the community at risk. Interdisciplinary disaster research therefore explores the interface between hazards and society in order to improve disaster risk reduction strategies. At this interface there exist disaster sub-cultures that are produced through hazard experience and can be developed as a coping mechanism for the at-risk communities. Therefore, disaster sub-cultures could contribute to either social resilience or vulnerability. The fluid nature of the term culture and the difficulty in quantifying these important human traits mean that the local sub-cultures are complex and often not included within conventional risk management tools such as risk maps. However, this paper demonstrates how a disaster sub-culture found at Mt Merapi volcano, Indonesia, can be examined using interdisciplinary methods. The distinctive Mt Merapi sub-culture influences local community actions during the frequent eruptions. The findings from ethnographic studies completed on Mt Merapi in 2007 and 2009 have been translated and mapped in order to be incorporated within a holistic risk assessment. The key findings, methods of translation and maps are presented here, and demonstrate the potential for interdisciplinary research applications in disaster risk reduction.     

Coping with seismic vulnerability: small manufacturing firms in western Athens

This paper attempts to contribute to international discourse on the responsibility of macro structures (economic and political) and private agencies for the production and distribution of vulnerability. It does so by focusing on an individual economic entity, small manufacturing firms (SMFs), in a specific location, western Athens, Greece. By evaluating the losses that SMFs sustained in the earthquake of 7 September 1999, the paper points to variations in vulnerability levels among such firms and highlights the 'sources' of vulnerability they confront. Furthermore, the SMF recovery cycle is systematically monitored in parallel with relevant public policies and state reactions to private recovery methods. The analysis illustrates processes that externalise recovery costs, alter the relationship between physical and socio-economic vulnerability and shift the vulnerability load from macro structures to individual agencies or vice versa. It is based on two methodological approaches: the division of vulnerability into three constituent components (exposure, resistance and resilience); and the conceptual split between producers and carriers of vulnerability.
