Disaster recovery is a dynamic process of creating, maintaining, and changing the meaningful context of survivors. It is completed when they redevelop their self‐reliance and resume managing their social relations with a sense of community. This study employed action research to examine how researchers and survivors collaborated to change disaster recovery through the generative power of metaphor in a small village in Japan that experienced the Niigata–Chuetsu earthquake on 23 October 2004. It outlines long‐term collaborative practices as survivors undertook new activities owing to the power of the metaphor of ‘school’. Once ‘school’ was adopted as the metaphor for where survivors learnt new skills and passed on traditional knowledge, they created new metaphors and performed new activities independently, which is critical for recovery as it demonstrates self‐reliance. The paper assesses the reasons why generative metaphors worked effectively in this case and highlights some academic and practical implications for disaster recovery. 相似文献

Home buyout programs facilitate the permanent relocation of residents away from areas considered to be at risk from future hazards, though few studies have examined the impacts of home buyout programs on affected households and communities beyond the program implementation period. In this paper, we examine between-neighborhood variation in key recovery indicators for three neighborhoods that followed different paths to recovery after Hurricane Sandy: one that rebuilt in situ, one that participated in a buyout and relocated, and one located immediately adjacent to the buyout zone. Three years post-disaster, buyout participants are faring worse in terms of place attachment and social capital compared to residents in the other two neighborhoods, while the neighborhood adjacent to the buyout zone is also showing signs of decline. These findings suggest that the social costs of buyouts extend well into the recovery period, and that the place-based ties and social networks that would typically help individuals cope with disaster impacts and persevere through adversity may be diminished for buyout participants, ultimately hindering their recovery. We conclude with a discussion of the implications of buyouts on participating and affected communities, as well as implications for research and policy. 相似文献

The material flow approach provides a framework from which to address resource management and estimate gross environmental impacts, both spatially and temporally. In this article, the major flows of zinc in Oceania over its entire life-cycle are examined; these include production (mining, milling, and refining), fabrication and manufacturing of semi- and finished products, use, and the waste management system. Comprehensive mass balances were applied to determine the zinc flows, including the quantities of zinc entering stocks in waste and in-use reservoirs. The Oceania cycle shows that substantial amounts of zinc (about 1120Gg/year) are mined on the continent. The total flow of zinc in finished products entering the use stage is about 8.6kg/(capita.year), substantially exceeding the zinc flow in discarded products. This difference, about 7.2kgZn/(capita.year) on average, is added to the in-use reservoir, largely for galvanizing applications in domestic construction and transportation. Less than 60% of all discarded zinc entering the waste management system is recycled. Much of the remaining discarded zinc is diluted into other waste streams, where recovery and recycling are probably not economically feasible. 相似文献

The Resource Management Act (RMA) legislates the management of most natural resources in New Zealand. The RMA invokes ecosystem-based
management by requiring that regulation be based on managing the effects of resource according to “the life supporting capacity”
of the environment. The management of water resources under the RMA is carried out at the regional level by regional councils.
Regional councils can develop regional water plans to establish objectives and criteria for water management. Regional water
planning under the RMA has been problematic, and regional plan objectives developed under the RMA have been criticized as
too broad and not sufficiently quantified. As a consequence, many resource users are unconvinced of the need for the regulatory
criteria promulgated by plans, whereas other groups are concerned that the environment is inadequately protected. This article
proposes that a lack of ecologically relevant management units has prevented regional water plans from fulfilling their intended
function under the RMA. Then it introduces the use of River Environment Classification as a means of defining units for assessment
and management, and provides three case studies that demonstrate its potential to support regional water management planning.
The discussion shows that the specificity of regional assessments can be increased if ecologic variation is stratified into
distinctive units (i.e., units within which variation in the characteristics of interest is reduced) as part of the assessment
process. The increased specificity of the assessments increases the possibility that regional objectives and criteria for
water management can be derived that are quantitative and justifiable and that provide certainty for stakeholders. The authors
conclude that greater choice and meaning can be generated in regional planning processes if regional variation in ecologic
characteristics is stratified using a classification, and if classes are used as units for assessment and management. 相似文献

This is a study of individual differences in environmental problem-solving, the probable roots of these differences, and their implications for the education of resource professionals. A group of student Resource Managers were required to elaborate their conception of a complex resource issue (Spruce Budworm management) and to generate some ideas on management policy. Of particular interest was the way in which subjects dealt with the psychosocial aspects of the problem. A structural and content analysis of responses indicated a predominance of relatively compartmentalized styles, a technological orientation, and a tendency to ignore psychosocial issues. A relationship between problem-solving behavior and personal (psychosocial) style was established which, in the context of other evidence, suggests that problem-solving behavior is influenced by more deep seated personality factors. The educational implication drawn was that problem-solving cannot be viewed simply as an intellectual-technical activity but one that involves, and requires the education of, the whole person. 相似文献

The interrelationship of society and environment is addressed here through the study of a remote fishing village of 750 people. An interdisciplinary study evaluated demographic, economic, and social aspects of the community, and simulation modeling was used to integrate these societal characteristics with environmental factors.The population of the village had grown gradually until the 1960's, when a decline began. Out-migration correlated with declining fish harvests and with increased communications with urban centers. Fishing had provided the greatest economic opportunity, followed by logging. A survey was conducted to investigate the costs and revenues of village fishermen. Diversification characterized the local fleet, and analysis showed that rates of return on investment in the current year were equal between vessel types.The variable levels and rate parameters of the demographic, economic, and social components of the model were specified through static and time series data. Sensitivity analysis to assess the effects of uncertainty, and validation tests against known historical changes were also conducted. Forecast scenarios identified the development options under several levels of fish abundance and investment. The weight given to ecological versus economic resource management registered disproportionate effects due to the interaction between investment and migration rates and resource stochasticity. This finding argues against a golden mean rule for evaluating policy trade-offs and argues for the importance of using a dynamic, socio-ecological perspective in designing development policies for rural communities. 相似文献
