ABSTRACT Despite a notable increase in the literature on community resilience, the notion of ‘community’ remains underproblematised. This is evident within flood risk management (FRM) literature, in which the understanding and roles of communities may be acknowledged but seldom discussed in any detail. The purpose of the article is to demonstrate how community networks are configured by different actors, whose roles and responsibilities span spatial scales within the context of FRM. Accordingly, the authors analyse findings from semi-structured interviews, policy documents, and household surveys from two flood prone areas in Finnish Lapland. The analysis reveals that the ways in which authorities, civil society, and informal actors take on multiple roles are intertwined and form different types of networks. By implication, the configuration of community is fuzzy, elusive and situated, and not confined to a fixed spatiality. The authors discuss the implications of the complex nature of community for FRM specifically, and for community resilience more broadly. They conclude that an analysis of different actors across scales contributes to an understanding of the configuration of community, including community resilience, and how the meaning of community takes shape according to the differing aims of FRM in combination with differing geographical settings. 相似文献

珠江三角洲洪水变化及洪水风险与保险 总被引：5，自引：2，他引：3
珠江三角洲经济发达,河网密布,洪水问题一直比较突出。原因不仅在于这一区域内水系交错、堤围众多、洪水时空分布不均,还在于伴随该区域经济发展及受人类活动影响的洪水变化。人们对利益与洪水风险的取向直接决定了本区域洪水灾害损失的程度和抗御洪灾的能力。在各种防洪减灾的工程和非工程措施中,洪水保险是值得重视并应尽快开展的工作。 相似文献

Questions of justice have been raised in recent years when contending with the social costs of urban sprawl. But this field of inquiry suffers from the difficulty of translating the abstract notion of justice into measurable spatial indices. The aim of this paper is to empirically measure the liberal notion of justice in the metropolitan region of Tel Aviv by adopting Pierre Bourdieu’s theory of three forms of capital. Under this theory, the formation of economic, cultural, and social capital in the individual’s living environment determines the person’s exposure to different sets of life-chances (i.e., capabilities), thus influencing equality of opportunity (i.e., social justice) in space. The analysis reveals that suburban inhabitants benefit from a larger accumulation of the three forms of capital than do urban inhabitants. Accumulation of these capitals has a positive effect on exposure to life-chances, thus enhancing spatial segregation between cities and suburbs. 相似文献

Improved estimates of UK flood risk during a period of increased climatic variability place challenges on existing methods that rely on short instrumental records. This paper examines the value of using historical data (both documentary and epigraphic) to augment existing gauged records for the River Tay at Perth as part of a multi-method approach to assessing flood risk. Single station and pooled methods are compared with flood risk estimates based on an augmented historical series (1815–2000) using the Generalized Logistic and Generalized Pareto distributions. The value of using an even longer, but less reliable, extended historical series (1210–2000) is also examined. It is recommended that modelling flood risk for return periods >100 years should incorporate historical data, where available, and that a multi-method approach using a high threshold Generalized Pareto distribution can also add confidence in flood risk estimates for return periods <100 years based on standard methods. 相似文献

空间正义与新型城镇化研究的方法论 总被引：3，自引：0，他引：3
在经济社会转型和进入新常态的背景下,以往重数量、规模扩张和经济效益的快速城镇化模式引发的许多空间不公正问题开始突显出来,如何实现土地资源配置、空间发展权利等方面的公平,亟需用空间正义的理论思维去反思和重构中国的城镇化发展模式。空间正义理论具有社会空间、多尺度性、批判建构三个主要特征,它们对城镇化研究和实践产生重要影响。西方地理学界对空间正义已有较充分的理论讨论,实践案例亦很丰富,国内还处在初步了解和探索的阶段,缺少适合中国体制和社会发展需求的理论。通过对空间正义思想与理论的梳理,提倡综合运用多种方法,进行多尺度、多主体综合分析和案例比较,探讨和总结基于空间正义的中国城镇化演化机理与发展模式。在社会空间辩证法的指导下,运用定性、多尺度、多智能体的方法,揭示中国城镇化进程的演变机制,寻找改善途径进而实现城市空间正义。将空间正义思想用于城乡发展与规划,可为城镇化研究提供新视角,并引导城镇化转型,实现经济社会及城乡的常态发展。 相似文献

Sustainable flood management: oxymoron or new paradigm? 总被引：2，自引：0，他引：2
Alan Werritty 《Area》2006,38(1):16-23
The existing paradigm of UK flood risk management that privileges structural solutions over non-structural ones is evolving in response to threats posed by climate change and higher environmental standards required by the EC Water Framework Directive. This paper examines the contrasting reactions of DEFRA and the Scottish Executive. The Scottish 'experiment', which embraces a strong definition of sustainability, is contrasted with a weaker version emerging in England and Wales. Divergent levels of risk and histories of managing that risk explain many of these contrasts. Scotland's more radical approach has the potential to become a new paradigm. 相似文献

基于“H-E-V”框架的城市洪涝风险评估研究进展 总被引：1，自引：1，他引：0
在全球气候变化与城市扩张的背景下,城市洪涝问题频发并引发严重的社会问题与经济损失。当前城市洪涝管理的主要内容已从工程性防御性措施转向洪涝风险管理,而城市洪涝风险评估又是城市洪涝管理的关键环节。基于此背景,论文首先介绍了IPCC采纳的城市洪涝风险评估框架“危险性(Hazard)—暴露性(Exposure)—脆弱性(Vulnerability)”即“H-E-V”的概念内涵,在此基础上梳理了其危险性、暴露性、脆弱性3大要素的主要研究内容,探讨分析不同研究方法的优缺点。最后提出了城市洪涝风险评估的主要发展趋势及关键问题,主要有以下4个方面：①危险性方面,建立适应于城市地区的耦合型二维洪涝淹没模型是洪涝风险评估要求下的必然趋势;②暴露性分析在大数据及GIS技术支撑下正逐步精细化、动态化;③脆弱性正从早期侧重的物理维度定量评估转向社会、经济、文化、环境等多维度的评估;④此外,气候变化与城市扩张下的多情景城市洪涝风险评估是未来城市洪涝管理的研究热点与难题。 相似文献

Initiatives designed to bring about social and spatial change, whether implemented by governments, international agencies, nongovernment organizations or private companies, invariably have an impact on how people perceive ‘places’– defined as spaces with particular meanings. In southern Laos and northeastern Cambodia the ethnic Brao peoples are facing rapid social and spatial changes as a result of a wide range of initiatives, many of which are associated with ‘development’. Case studies on internal resettlement from the uplands to the lowlands, the redesigning of living spaces, and the implications of protected national park establishment and management are discussed in relation to a four‐point typology of what is required to constitute place. The role of social and spatial (re)organization on place amongst the Brao is considered, including how peoples' conceptions of place are being altered and how the Brao are variously responding to efforts to (re)organize them and reconstitute their places. 相似文献

The study of flood hazard has been a key theme within the spatial analysis of natural hazards. A number of authors have expanded on this tradition by adopting a society‐oriented approach to risk perception. Thus a new framework has become available for exploring social response to risk and describing the relationship between human communities and hazards in terms of contemporary interpretative categories such as social representation and “stigmatization,” the latter defined as the process by which media and social actors mark places affected by disastrous events as dangerous and unsafe sites. This literature has made a vital contribution to the geographical reading of flood hazard, showing how flood risk generates both space‐ and place‐making processes. In this paper I discuss the relationship between these two processes, suggesting that the political response to flood hazard may be viewed as a hetero‐directed strategy that influences place‐making at a local level. I illustrate this perspective using a field research conducted in 2006–2007 on the Po River Basin in Piemonte, an Italian region with high flood risk that has been affected by a series of events in recent decades. 相似文献

El Hatillo is a rural community in the Sébaco valley in Nicaragua, which suffers from an eroding resource base, high levels of poverty and malnutrition, and a high susceptibility to hazards. Structural adjustment policies have been devastating for small and subsistence farmers and have increased the level of economic, social and environmental marginalisation in rural Nicaragua. This paper explores initiatives to promote sustainable development in Nicaragua in the context of structural adjustment and environmental degradation. Drawing on qualitative research conducted in El Hatillo, it outlines the ways in which women in this community are attempting to address the multiple challenges of rural poverty and environmental risk and considers the potential of these strategies for gender equality. 相似文献

In recent years, social media emerged as a potential resource to improve the management of crisis situations such as disasters triggered by natural hazards. Although there is a growing research body concerned with the analysis of the usage of social media during disasters, most previous work has concentrated on using social media as a stand-alone information source, whereas its combination with other information sources holds a still underexplored potential. This article presents an approach to enhance the identification of relevant messages from social media that relies upon the relations between georeferenced social media messages as Volunteered Geographic Information and geographic features of flood phenomena as derived from authoritative data (sensor data, hydrological data and digital elevation models). We apply this approach to examine the micro-blogging text messages of the Twitter platform (tweets) produced during the River Elbe Flood of June 2013 in Germany. This is performed by means of a statistical analysis aimed at identifying general spatial patterns in the occurrence of flood-related tweets that may be associated with proximity to and severity of flood events. The results show that messages near (up to 10 km) to severely flooded areas have a much higher probability of being related to floods. In this manner, we conclude that the geographic approach proposed here provides a reliable quantitative indicator of the usefulness of messages from social media by leveraging the existing knowledge about natural hazards such as floods, thus being valuable for disaster management in both crisis response and preventive monitoring. 相似文献

The increase of extreme meteorological phenomena, along with continuous population growth, has led to a rising number of flooding disasters. Therefore, there is an urgent need to develop better risk reduction strategies, among which is increased social resilience. Experiencing a disaster is recognized as a factor that positively influences overall community resilience, with particular effects on social resilience; it appears to be more influential than school education. It also has many negative effects, though. Previous studies underline that citizens do not distinguish between different types of experiences. Thus, we investigated whether a simulated experience of a flood can improve social resilience, without being hampered by negative repercussions. The study was executed in five municipalities in three Italian regions involved in the European project LIFE PRIMES, which planned simulation activities for each studied area. Data, collected through the administration of anonymous questionnaires before and after a flood drill, were processed by applying a multicriteria decision analysis tool (PROMETHEE). Results show that the drill significantly augmented perceived social resilience in the smaller studied communities but not in the larger ones, a fact that should be further investigated. Key Words: multicriteria decision analysis, simulated flood experience, social resilience to disasters. 相似文献

Community cooperation with natural flood management: a case study in the Scottish Borders 总被引：1，自引：0，他引：1
The cooperation of communities and landowners in the upper catchment is vital for the successful implementation of natural flood management (NFM) projects as few incentives are in place to reward them to host such projects. The aim of this paper is to initiate an exploration of the issues that affect a community's decision to cooperate. The results of a case study in Scotland show that willingness to cooperate is affected by concern about alternative flood management techniques, a sense of responsibility to help connected communities at risk of flooding and the expectation of beneficial impacts from the project. Indeed, these issues appeared to over-ride the hostility generated towards the project as a result of poor communication and engagement with the community from organisations associated with the proposed project. The results of the research suggest that if NFM projects are to proliferate, close attention must be paid to community attitudes towards flood management and related communities at risk, and that NFM projects must be developed and implemented according to well-established principles of public participation. 相似文献

The state of Kerala in India is known for its active civil society and the massive decentralization campaign launched in 1996. However marginalization of tribal communities hampers the state's decentralized environmental management strategies. The proposed construction of a dam along the Chalakkudy River will displace two colonies of the Kadar tribe in Chalakkudy and Athirapilly towns, destroy habitats of local wildlife and devastate unique riverine vegetation endemic to the region. This brings to light issues of social and environmental justice as well as a wider responsibility to protect and preserve unique flora and fauna. The state's decentralization strategies, as they relate to tribal communities, lack consideration of local power distribution and cultural conditioning. This raises questions about the state's role in social justice as well as biodiversity conservation. In 2010 and 2011, the author's interviews in Chalakkudy and Athirapilly towns reveal that tribal communities perceive that their place in society restricts their contribution regarding natural resource management and use. The paper suggests that unless the culture of planning and decision making in the state are changed, decentralized strategies will be ineffective, resulting in a predominately top‐down approach towards natural resource management, and will negate Kerala's goal of democratic decentralization. 相似文献

Many real-world spatial planning and management problems give rise to a geographical information system (GIS)-based multi-criteria decision-making. Analytical network process (ANP) provides a comprehensive methodology for representing complex multi-criteria decision-making problems as a network of criteria and alternatives, where feedback and interdependence relationships may exist within and between all the criteria and alternatives. Experts’ experiences are used to estimate relative magnitudes of tangible and intangible factors through paired comparisons in order to make rational and consistent decisions. However, the GIS-based ANP, an adoption of weighted linear aggregation rule, typically employed a high trade-off decision strategy and neglected other decision strategies. This paper develops a novel GIS-based multi-criteria evaluation (MCE) procedure by extending the ANP using fuzzy quantifiers-guided ordered weighted averaging (OWA) operators. This extension, which generalizes the aggregation process used in the ANP, would provide a generic powerful decision-making tool that allows decision-makers to define a decision strategy on a continuum between pessimistic (risk-averse) and optimistic (risk-taking) strategies. By changing the linguistic quantifiers, the GIS-based ANP–OWA can generate a wide range of decision strategies taking into accounts the level of risk the decision-makers wish to assume in their MCE. A land-use suitability analysis in a region of Saudi Arabia is presented to demonstrate the application of the proposed procedure. 相似文献

Abstract Students often ask whether the examples we give as instructors have any relevance to their worlds, to their lives. Too often the answer is no. This paper describes a case that is obviously pertinent to both secondary and university students and their instructors. The legal battle over equality and racial discrimination in the New York City School system presents not simply a rich field for geographical consideration but also a pertinent one. It brings to students and their instructors a complex of economic, legal, and social issues played across a discrete spatial surface. As importantly, it offers a case study exploring the difficulties of both defining and then achieving distributive justice in post-modern environments in a context students and their instructors will recognize as relevant and timely. The discussion that results may be useful in economic, legal, locational, and social geographic instruction. 相似文献
