This research is part of an effort to monitor houses built for victims of hurricane Fifi in 1975. After 3 years (1978) we interviewed the residents to determine the rate of continued occupancy and the amount of housing improvement and the correlates of both. We found that a significant number of small families, Protestants, and families that had not participated in the construction of the housing had moved. From what we could determine, moving was primarily related to seeking work and improving one's financial position.
Nearly 90% of the permanent occupants had improved their houses with either indigenous or manufactured materials. Non-improvement of houses was concentrated among families with few members. The largest number of unimproved houses was located in the project that sewed the poorest victims and contained the cheapest housing. 相似文献

综合遥感解译、宗地调查和入户问卷调查方法,研究黄淮海平原农区禹城市5个村庄的宅基地时空演变特征和不同退出标准的宅基地整治潜力和整治效果。研究结果表明:(1)改革开放以来,农村宅基地经历了剧烈扩张,调研村庄的宅基地平均扩张了3.7倍。2015年户均宅基地高达1.6宗,30.8%的农户存在“一户多宅”现象,28.5%的房屋被闲置或废弃。(2)2000年以前,调研村庄的宅基地空间扩张模式以飞地式为主,2000年后被填充式和蔓延式所取代。分村庄来看,宅基地空间扩张受到主要交通干线布局、土地资源禀赋和村庄初始布局等因素的影响。(3)调研村庄宅基地整治具有较大的理论潜力,可节约56%的村庄居住用地。基于两套退出标准方案的宅基地整治可分别节约26%和36%的村庄居住用地,但均与理论潜力存在较大差距。(4)未来宅基地试点改革亟需在推进转移人口市民化、建立宅基地退出补偿价值体系、探索退出的宅基地转化为集体经营性建设用地的办法等宏观体制机制推进,并在微观层面依据农户就业结构和土地资源禀赋分类施策。 相似文献

The purpose of this study is to quantify the marginal willingness to pay (MWTP) for clean air in China. We provide the first estimate of MWTP for clean air by implementing a hedonic method using housing price and air quality data from Shanghai. Our estimates imply that air pollution has a significant and negative impact on housing price. We also find that the willingness to pay for better air quality varies significantly across different income groups. This paper helps to deepen our understanding of the economic impacts of air pollution in emerging Asian metropolises where residents are suffering from the most severe respiratory health problems. 相似文献

Urban forest ecosystems are complex and vulnerable social–ecological systems. The relationship between urban forests and housing is particularly variable and uncertain. We examine the influence of building renovation and rental housing on public trees at the parcel and street-section scale in a residential neighbourhood in Toronto, Canada. We use empirical data describing multiple tree inventories and government open data describing building permit applications to test for effects on urban forest structure, tree mortality, and tree planting. We found that the presence and number of building permits significantly predicted mortality at both scales, while planting was positively correlated with building permits at the street-section scale only. Multi-unit parcels had significantly lower rates of planting than single-unit parcels and multi-unit housing was positively correlated with mortality at the street-section scale. These findings suggest that where concentrated changes in housing stock are occurring, substantial losses of trees and associated ecosystem services are possible. 相似文献

Assessing the impact of the Indian Ocean tsunami on households: a modified domestic assets index approach 总被引:1,自引:0,他引:1

This paper offers a potential measurement solution for assessing disaster impacts and subsequent recovery at the household level by using a modified domestic assets index (MDAI) approach. Assessment of the utility of the domestic assets index first proposed by Bates, Killian and Peacock (1984) has been confined to earthquake areas in the Americas and southern Europe. This paper modifies and extends the approach to the Indian sub‐continent and to coastal surge hazards utilizing data collected from 1,000 households impacted by the Indian Ocean tsunami (2004) in the Nagapattinam district of south‐eastern India. The analyses suggest that the MDAI scale is a reliable and valid measure of household living conditions and is useful in assessing disaster impacts and tracking recovery efforts over time. It can facilitate longitudinal studies, encourage cross‐cultural, cross‐national comparisons of disaster impacts and inform national and international donors of the itemized monetary losses from disasters at the household level. 相似文献

ABSTRACT: The hedonic valuation method was used to quantify the impact of floodplain location on housing values in Fargo‐Moor‐head. Being located in the 100‐year floodplain lowered the home values by $8,990, and such homes were worth $10,241 less than similar homes located outside the floodplain before the major flood event of 1997. Required flood insurance premiums for these homes were determined to account for approximately 81 percent of this price depreciation. In contrast, homes in the 500‐year floodplain were worth $3,100 more than similar homes not in the floodplain. It was concluded that more disclosure is needed regarding the location of the 500‐year floodplain, and that the hedonic valuation method can be used to calculate the economic gains and losses associated with flood mitigation projects or floodplain remapping efforts that result in the reclassification of the legal floodplain status of individual homes. 相似文献

An exploratory study on perceptions of seismic risk and mitigation in two districts of Istanbul 总被引:1,自引:0,他引:1
Istanbul is one of the world's cities most vulnerable to seismic events. According to seismologists, the probability of a severe earthquake in the next 30 years is approximately 40 per cent. Following an outline of the seismicity of this vital Turkish city and a summary of current seismic risks and mitigation studies, this paper presents the results of a survey conducted in two districts of Istanbul, Avcilar and Bakirkoy. The survey comprised some 60 questions on the seismic risk perceptions of individuals and requested basic personal data, such as on age, education level, employment type, financial income, and gender. Despite various differences among the survey population, such as academic background and level of financial income, responses were surprisingly similar, especially in terms of having no plan for a safer house. The data may help those planning mitigation programmes and public awareness campaigns on preparedness and particularly mitigation in highly vulnerable regions. 相似文献

Social sustainability and neighbourhood design: an investigation of residents' satisfaction in Delhi
Social and environmental goals are often mutually reinforcing. Urban forms may encourage social sustainability as well as social inclusion or may have the potential to create areas of crime and social exclusion. The issues of relationship between sustainable development and urban form have given birth to new paradigms of design approach such as new urbanism, the compact city and the eco-city. This paper examines the impact of urban form on social sustainability at the neighbourhood level. It seeks to better understand the relationship between urban form and social sustainability by comparing three neighbourhoods with dissimilar urban forms in Delhi, India. Household surveys and observation surveys in these three neighbourhoods were conducted, and it was found that the urban form of a neighbourhood plays a very important role in creating a socially sustainable residential neighbourhood. The study established that social interactions within the communities are higher when dwelling units are placed around the public realm or common open space. The study demonstrated that provision of high quality and well-located open space at the precinct level, mixed land use and good accessibility to the public realm and social infrastructure play an important role in increasing the social sustainability of the neighbourhood. 相似文献
