This research aims to investigate the extent to which urban and rural residents trust grassroots-level institutions and how this might affect community resilience to environmental change in China. It focuses on the commitments of institutional actors and their capacities to manage natural hazards and coordinate the community's response. Semistructured interviews were conducted with megacity (Tianjin) and remote village (Wolong) residents in China. We found that public confidence in grassroots-level institutions is limited due to inherent constraints on resources and power. Residents of Wolong tend to recognize the commitment and role of those institutions in connecting individuals with one another, whereas their urban counterparts in Tianjin remain skeptical. Issues of solidarity might account for this difference. These findings will have implications for state–society cooperation and disaster risk comanagement in both urban and rural China.  相似文献

The 2005 Atlantic hurricane season was unprecedented in terms of storm activity in the United States, Mexico, Central America and Caribbean. Given the impacts of hurricanes Katrina and Rita, the Honduran Mosquitia sparked little attention despite being hit by two hurricanes and a tropical storm in 2005. This article recounts the history of these storms in the Afro-Caribbean community of Batalla, drawing from public weather advisories and testimony of local residents obtained through participatory research. We contextualise this local history with results from the first paleotempestological study undertaken in the Mosquitia to shed light on long-term risk of catastrophic storms in the region and to demonstrate the value of integrating these two research approaches. Our findings contribute to recent ethnographic research on hazards by describing how a coastal people understand and respond to tropical cyclones and how landscape change influences the vulnerability of a coastal area. Although residents have not witnessed a storm as intense as those documented in the paleotempestological record, their knowledge and perceptions show how tropical cyclones can be disasters while leaving behind no sedimentary records. The paleotempestological evidence, however, reminds us that catastrophic hurricanes have struck the Mosquitia in the past and will do so again in the future. Understanding the interactions between contemporary human perceptions and responses and long-term hurricane risk provides insight for emergency managers and local stakeholders to better prepare for such a catastrophic event.  相似文献

Adaptation is a key concept in long‐term human adjustments to climate change. Despite the centrality of human decisions and actions in adaptation, much of the climate change literature is thin on humanities and social science which are the primary approaches for understanding human activity. This situation is particularly pronounced in Louisiana's discussions about its disappearing coast line where research has concentrated in understanding biophysical processes and solutions prioritize short‐term adaptations. This paper reviews the relationship of adaptation and long‐term transitions in the global change discussion and traces how disjointed adaptations in coastal Louisiana have contributed to a perilous environmental situation there. It proposes a shift from discrete adaptations to efforts that incorporate interrelated biophysical and human adaptations that can sustain long‐term transitions.  相似文献

Social capital can enhance community resilience to environmental change. Productive and trusted relations among social actors and effectual social norms can help local residents share resources, information and risks. The main objective of our study is to understand the ways in which social attributes and risk considerations influence adoption of resilient economic measures by individuals for reducing potential losses due to catastrophic rainstorm and flooding. This article provides evidence from China on how social capital contributes to anticipatory adaptation to environmental change. The inquiry is based on structured interviews with local residents of Tianjin, a flood-prone port city in China, and a standard regression analysis. Findings show that the intention to make preparation increases with the levels of social expectation, social relationship, and institutional trust. Perceived risk and damage experience, however, have no significant impacts. This suggests that building social capacity and trust will be more effective in enhancing community resilience than merely increasing awareness of hazard risks. We call for greater efforts on strengthening the capacity of formal and informal communal institutions. The structural changes required, however, are challenging.  相似文献

Hurricanes represent a common threat to coastal communities, affecting livelihood strategies and assets. Households are resilient if they can recover from a stress or shock while maintaining and arranging assets to secure a sustainable livelihood. The objective of this research is to measure the degree of resilience in the coastal households of Oaxaca, Mexico, following a hurricane using the asset approach and describing diversity, connectivity, and slow variables. The results show different degrees of resilience among the households and that social, natural, and financial capital are relevant to resilience. The diversification of income, savings, community help, natural resource use, and government transfers is among the most important assets. In particular, social capital and natural capital determine the structure and dynamics of the system.  相似文献

In the context of disaster normalization, the concept of “resilience” has been gradually introduced into the field of disaster prevention and mitigation in urban communities. In order to resist the increasingly frequent disasters caused by extreme weather, it is necessary to shift the focus of building resilient urban communities to the level of stormwater management. Community resilience is a disaster prevention and mitigation capability based on community resources. In order to solve the deficiency of storm and flood management in the current construction of resilient communities in China, it is necessary to establish a quantitative evaluation system to evaluate it. This paper uses the analytic hierarchy process and Delphi method to establish a community resilience evaluation system from the perspectives of community material space level, community management level and individual level. Then three communities in Hefei City, Anhui Province are selected for practical application of the system, and corresponding optimization and transformation strategies are proposed. The results show that: (1) The resilience of community stormwater management is closely related to the integrated environment of the community, the allocation of flood control facilities and the daily disaster prevention and mitigation management; (2) The ability of disaster prevention and mitigation and the awareness of public participation of the residents in all communities are relatively weak, and the communities invest less in the popularization of stormwater management wisdom; and (3) Resilient communities should not only pay attention to the construction of non-engineering disaster prevention measures, but also to the application of small-scale green infrastructure oriented toward stormwater management.  相似文献

ABSTRACT

The aim of the study on which the article is based was to identify groups of communities with similar resilience profiles, using Norwegian municipalities as a case. The authors used a set of socioeconomic and environmental indicators as measures of municipalities’ resilience and performed a cluster analysis to divide the municipalities into groups with similar multivariate resilience signatures. The results revealed six groups of municipalities that, apart from their unique combinations of indicator scores, featured certain spatial patterns, such as an “urban cluster” with urbanized municipalities and a “suburban cluster” with municipalities concentrated around major cities. The authors conclude that municipalities in each of the groups shared aspects that made them either more or less resilient to natural hazards, which could make them potential targets for shared interventions. Additionally, the authors conclude that clustering can be used to identify municipalities with similar resilience features and that could benefit from networking and sharing operational planning as a way to improve their respective communities' resilience to natural hazards.  相似文献

Geography has discovered resilience theory, a body of thought about ecological change that initiated with C.S. Holling in the 1970s. We describe the similarities and differences between resilience theory and a geographical treatise, Thomas Vale's (1982) book Plants and People. Vale's work draws more from the tradition of field botany and plant succession than from the theoretical and mathematical ecology that prompted Holling's ideas. Yet like resilience theory, Vale's model of ecological change emphasized multiple states, the threshold transitions between them, and their irreversibility. Each described how forests and rangelands can flip between stability domains in response to altered fire regimes, modified grazing pressures, and climate change. Plants and People also recognized the dual nature of stability encapsulated in Holling's formalization of engineering and ecological resilience. Although resilience theory predates Vale's work and retains primacy through its citation record, we show how their partial consilience promotes a more critical understanding of resilience theory and the ways in which models, scale, and human values influence our comprehension of ecological change.  相似文献

Being resilient in the face of climate change seems especially important for island societies, which face the effects of rising temperatures, unpredictable rainfall, changing wind patterns and sea level rise. To date, most studies of adaptation and resilience among Pacific island communities have used indicators and methods rooted in Western science and neo-classical economics. These have been criticized as being locally irrelevant and inadequate to appreciate the dynamic nature and social structures of island communities and their capacity to adapt. This paper challenges the paradigm that defines resilience as a return to equilibrium, by using a non-equilibrium, cultural ecological lens. The non-equilibrium view of resilience sees the social systems of island nations as highly dynamic and undergoing persistent adaptation in the face of changing environmental factors. Field-based research undertaken in eight villages in Samoa found that, through constant exposure to environmental change over extended periods of time, communities have become resilient and are in a position to adapt to future changes. In developing future policy in relation to climate change, Pacific island governments need to develop a more nuanced understanding of islanders’ perceptions and historical actions in the context of both their physical locations and their dynamic socio-cultural systems.  相似文献

为了推动陆海统筹,转变和优化临海产业布局,制定和完善海洋开发政策与体制建设,推进海洋经济发展和海洋强国战略,提高沿海区域经济发展韧性水平,中国自2011年以来先后启动海洋经济发展试点工作。旅游业是中国沿海区域经济的重要组成部分。论文以海洋经济发展试点政策作为准自然实验,基于2007—2020年中国沿海地区各地级及以上城市的面板数据,运用多期双重差分模型,总结和评估该试点政策对区域经济韧性及旅游经济韧性的影响。结果表明:海洋经济发展试点政策的实施能够显著推动区域经济韧性及旅游经济韧性的提升;而新冠疫情事件作为调节变量,削弱了海洋经济发展试点政策对区域经济韧性的影响。在区域异质性上,海洋经济发展试点对中南沿海地区经济韧性的政策效应最明显,而对华东沿海地区旅游经济韧性的政策效应则更为显著。鉴于此,合理扩大海洋经济发展试点,因地制宜规划沿海区域经济体系,对防范系统性风险、提高区域经济韧性及旅游经济韧性具有重要意义。  相似文献

For a national competition supported by the New Zealand Board of Geography Teachers, secondary school students in years 10–13 were asked to identify and investigate factors that were building community resilience in their home areas, and the entries provided young people's perspectives on how well individuals, families and communities ‘bounce back’, adapt, change and become stronger following an adverse event. This article concerns the findings of students at Greymouth High School. Their entries showed that community resilience in Grey District depended on individual and collective capacity for action. The greater their involvement in community affairs and projects, the more likely individuals and families were to form networks and participate in communal activities. In Greymouth, as elsewhere in New Zealand, membership of voluntary organisations and participation in planning for, and responding to, catastrophic events has helped residents respond effectively in times of adversity and has enhanced community resilience.  相似文献

Urban resilience, a new urban development and governance agenda, is being rolled out from the top down by a network of public, private, non-profit sector actors forming a global urban resilience complex: producing norms that circulate globally, creating assessment tools rendering urban resilience technical and managerial, and commodifying urban resilience such that private sector involvement becomes integral to urban development planning and governance. The Rockefeller Foundation's 100 Resilience Cities Program is at the center of this complex, working with the World Bank, global consultants, NGOs, and private sector service providers to enroll cities, develop and circulate urban resilience assessment tools, and create a market catalyzed by the notion of a resilience dividend. Notwithstanding the claim of this program being open and inclusive, aspects of its initial operationalization in Jakarta suggest that urban resilience assessment tools preempt alternative understandings of urban resilience and marginalizing voices of the city's most vulnerable populations.  相似文献

Agricultural development at Quitovac, a Sonoran Desert oasis that is an ancestral home of the Tohono O’odham people, was first interpreted in the literature as a typical example of an indigenous community succumbing to the economic pressures of industrial society. However, a humanistic analysis of the cultural and historical context and the results of ethnographic fieldwork leads to a radically different interpretation of recent community actions. Community‐initiated institutional and economic changes can be understood as creative and resilient adaptations, and perhaps a resolution, to a complex social and religious challenge to the community's identity. Notwithstanding the economic failure of part of the development efforts, the overall effects are interpreted as strengthening the residents’ sense of their home place and ensuring the continuation of religious rites associated with this sacred place.  相似文献

The impact of the 2004 Indian Ocean tsunami on coastal tourism communities highlights the vulnerability of tourism destinations to external shocks. Based on fieldwork conducted in Thailand in the wake of this disaster, this paper addresses one fundamental question: what sociopolitical and environmental conditions contributed to the vulnerability of the affected tourism community of Khao Lak in the southern Phang Nga Province. We argue that an understanding of the root causes of destination vulnerability is vital not only for the successful implementation of regional recovery plans, but also for building long‐term resilience against future shocks. In the absence of an appropriate tourism vulnerability framework, this paper analyzes Khao Lak's vulnerability through an innovative theoretical framework comprised of the sustainability vulnerability framework, relational scale and place. The findings reveal that Khao Lak's vulnerability is shaped by 13 interlinked factors. These are the complex outcomes of social norms and developmental and dynamic governance processes driven by the competing agendas and scaled actions of key government and industry stakeholders. The identification and understanding of the drivers of Khao Lak's vulnerability and a strong vulnerability framework have significant implications for the wider tourism community. First, the empirical findings provide tourism communities with a blueprint for understanding the foundations of their vulnerability to external shocks. Second, the tourism vulnerability framework presented here provides destination communities and government stakeholders with an analytical tool through which to analyze their unique sociopolitical conditions. Together, these empirical and theoretical contributions bring us closer to securing sustainable livelihood futures for tourism dependent communities.  相似文献

The ability of a community to withstand and recover from adversities including natural and man-made disasters has emerged as a major policy issue in recent years. This research aims to assess the role of institutional initiatives in building resilient communities and their response to natural disasters like the Gorkha earthquake in Nepal in 2015. The work is based on data collected from primary and secondary sources along with field observations. It is evident that resilient communities are equipped with greater coping capacities in the face of natural disasters and have reduced vulnerability to future hazards. Institutional capacity building and resilient construction including the School Earthquake Safety Program ensured better disaster preparedness. The traditional open spaces and building designs added to the structural resilience. There is, however, a need to build back better and to communicate earthquake-resistant designs to the affected communities.  相似文献
