Self‐help extensions to government‐built housing are now accepted as a valuable addition to the housing stock in many third world countries. This paper describes self‐help extensions being made to five‐storey walk‐up flats in Helwan, Egypt, to provide more living space for households which have grown too large for the two rooms initially provided. It is argued that the cooperative effort and standard of construction are resulting in an acceptable new environment. Government response should be to encourage and guide such extensions wherever they occur. 相似文献

There are some experts who are dealing with research on locally made materials for building in the Ministry of Housing and Works in Nigeria. It has been discovered in the Ministry that lateriate clays can be fired and used for building even two‐storey buildings depending on the firing and the pressure (Ogunbamwo, 1975). The Ministry has constructed a block of bungalows of low‐cost housing units with mud at Ikoyi, off Kingsway Road. No one will know that these houses are mud houses if not at closer inspection. Unfortunately, no effort has been made to continue or improve on this laudable adventure in Nigeria. 相似文献

ABSTRACT: Increasingly, residential development in urbanizing areas is accomplished by large housing projects, composed of clusters of townhouses or garden partments. It is hypothesized that the runoff from such developments should carry more pollution than that from the same number of housing units on separate plots, because the runoff is conveyed directly to drainage channels rather than being drained across lawns and gardens, which may absorb part of the pollutants. In order to evaluate this effect, storm event data were obtained from a planned unit development near Hightstown, N. J., using samples taken every 10 minutes throughout the storm at two different storm sewers. Results show heavy metals pollution about what had been anticipated, in accordance with the hypothesis given above, and BOD ammonia and phosphates higher than predicted. The results are significant for areawide water quality planning in metropolitan areas, where projections of future pollution loadings depends upon the land use. 相似文献

居住小区交通噪声概率分布特征及其评价 总被引:2,自引:0,他引:2
在连续35天监测的基础上,分析了道路交通流量的概率分布特征,发现道路交通流量在时间上呈对数正态分布。该分布导致小区交通噪声在时间上具有明显的正态分布特征,其中小区临街交通噪声在空间上也呈正态分布。将上述概率分布特征应用到小区道路交通噪声评价中,使得评价结果不仅具有一般的大小意义,还具有概率分布意义。 相似文献

This paper examines the realism of the resilience ambition and process of the U.S. housing system, shedding light on its heterogeneity as well as the financialization currently acting as the driving force in real estate production. The resilience ambition leading to enhanced justice and egalitarianism is understood as the provision and maintenance of post-disaster housing for all within an institutionally diverse landscape of housing policy makers and implementers. Particular emphasis is given to the post-Katrina institutional transformations resulting from multifarious interactions between multilevel institutional structures and a diverse landscape of low-income housing policy implementers – referred as social resilience cells (SRCs) in this paper. The nature and level of these transformations determine the degree to which resilience in its heterogeneous form has been incubated in New Orleans. The paper concludes with a discussion on the macro conditions and bottom-linked governance structures under which all SRCs could be better bolstered in a post-financialization, radicalised neowelfare U.S., and which in turn create possibilities for materialising the resilience ambition. 相似文献

Assessing the Ecological and Social Benefits of Private Land Conservation in Colorado 总被引:1,自引:0,他引:1

Abstract: Conservation of private land through conservation easements, development agreements, and clustered housing has increased greatly as have criticisms of the laws, public programs, and incentives that motivate landowners to use them. Rapid land‐use change at the urban–rural interface in Larimer County, Colorado, has given rise to programs that provide a variety of land‐conservation options for landowners. As of January 2005, roughly 60% of Larimer County was publicly owned, and 3% or 16,200 ha was privately owned with some form of protection. We used document analysis, a landowner survey, targeted interviews, and a landscape‐level spatial analysis to analyze the patterns, quantities, and qualities of private land conservation. We created a jurisdiction‐specific typology of desired benefits from local government‐planning documents to help evaluate conservation parcels. Most easements and other conservation documents used general terms and did not describe the site‐specific values of the land being conserved. Landowners were able to describe some benefits not included in parcel‐specific documents, and our spatial analysis revealed parcel‐specific and cumulative conservation benefits such as the amount of buffering, infill, connectivity, protected agricultural land, riparian protection, and other benefits not referenced by either documents or landowners. Conservation benefits provided by a parcel varied depending on its geographic location, the specific institution such as a land trust or open space program that a landowner worked with, and the conservation mechanism used, such as voluntary easement or residential clustering requirements. The methods we used provide a template for jurisdictions wishing to undertake a similar analysis. Our findings may assist other jurisdictions and institutions interested in improving how land‐conservation benefits are described; justify and inform future investments in private land conservation; assist local governments and other institutions with the assessment of program effectiveness; and be useful for conservation planners who wish to become more involved in on‐the‐ground implementation of conservation actions. 相似文献

The residential sector is the third largest sector of final energy use in Australian urban areas, accounting for about 12% of the country's total final energy consumption. What are the main determinants of energy consumption in the residential sector? This paper sheds light on this question by examining non-transport summer household energy consumption in Adelaide and Melbourne. Data were collected from a survey of 200 sample households and modelled according to a conceptual framework that not only emphasises household characteristics and housing stock characteristics but also controls the macro-environment factors. The findings reveal distinctive results in Adelaide and Melbourne. In Adelaide, household characteristics are the most important contributors in explaining non-transport household energy consumption. In Melbourne, the household characteristic as represented by income is important, but housing stock characteristics provide even more explanatory power. These findings contribute to the understanding of the factors that shape residential energy consumption and have policy implications in targeting household energy savings. 相似文献

Building permanent accommodation after a disaster takes time for reasons including the removal of debris, the lack of available land, and the procurement of resources. In the period in‐between, affected communities find shelter in different ways. Temporary houses or transitional shelters are used when families cannot return to their pre‐disaster homes and no other alternative can be provided. In practice, families stay in a standard interim solution for months or even years while trying to return to their routines. Consequently, they adapt their houses to meet their midterm needs. This study analysed temporary houses in Chile and Peru to illustrate how families modify them with or without external support. The paper underlines that guidance must be given on how to alter them safely and on how to incorporate the temporary solution into the permanent structure, because families adapt their houses whether or not they are so designed. 相似文献
