Urban sprawl is a challenge of the century across the globe; however its greatest impact is felt more in developing countries mainly due to its poor planning and ever increasing population. To ascertain how this affects a notable African city, Abuja, a questionnaire design was employed to elicit resident's perception on the causes and effects of sprawl in the city. A principal component analysis was performed to simplify the relationship between large bodies of variables involved. This was able to collapse the 14 variables representing the causes of sprawl extracted from the response of the respondents and 9 variables representing the effects of sprawl on the environment and on the residents into significant and orthogonal components that explained the variables in the observed data. Among the nine factors that loaded highly on the components, population was the major factor discovered to be responsible for the sprawl. The analysis further showed the main effects of the sprawl on the city as: loss of biodiversity, high dependency on car, traffic congestion, land degradation, alteration of microclimate, destruction of aesthetics, increasing crime wave, pollution and waste management problems. Adhering to the guidelines on urban development for the city will help the residents not to be prone to the effects of urban sprawl and help to maintain good environmental standards and less spending on maintenance on the part of the government.

Public housing programs have been the major tool for providing shelter in Abuja City, Nigeria. The purpose of the study was to determine the relationships between housing satisfaction and structure types, building features, housing conditions, neighborhood facilities, management, and demographic/socioeconomic characteristics. The main objective was to develop a model for determining factors which affect housing satisfaction in public housing in Nigeria. The sample of 1,089 households was randomly selected from the residents living in 19,863 public housing units in Abuja City. The public housing units were built and are managed by the Federal Capital Development Authority (FCDA). All data for the study were collected through self-administered questionnaires, which had been developed, pretested, and revised. The instrument measured the residents level of housing satisfaction on a five-point Likert scale. The data were analyzed using descriptive statistics, analysis of variance, multiple regression, and correlation analysis. The majority of the sample was households of more than four persons, headed by males from 31 to 40 years of age. The respondents were well educated, renters, and employees of the federal ministries. The residents expressed dissatisfaction with their overall housing situation; however, a significant positive relationship was found between housing satisfaction and satisfaction with structure types, building features, housing conditions, neighborhood facilities, and housing management. The mean satisfaction score for the room units differed significantly (p .05) from the means for the other structure types. Residents of the room units were less satisfied than any other residents. Privacy within the house had the strongest effect on satisfaction with building features. Interior construction quality had the greatest influence on satisfaction with housing conditions, while cleanliness of the neighborhood had a strong effect on neighborhood satisfaction. FCDA housing officials attitudes affected residents satisfaction with management. The model variable that contributed most to the explanation of variation in overall housing satisfaction was management. However, all five of the single-item measures contributed significantly to the prediction of housing satisfaction. Government housing policy should encourage a decent living environment, effective housing management, and construction of high quality structure types which incorporate users needs and preferences. ; Ph.

The article examines the criminalization of street vendors in Abuja, Nigeria. It draws on the debate on informality, legality and rights, to highlight the tensions surrounding the law as a mode of regulation. As documented, ideology provides the rationale for the criminalization of street vending. The activity is deemed inimical to the modernist ideals of a clean and functioning city. Enforcement of the law is accompanied by the harassment of vendors. However, vendors remain on the streets by circumventing the law. The article highlights the shortcomings of a simplistic approach to the governance of informality. It cannot be legislated away.

Waste in the construction industry has been the subject of several research projects around the world in recent years. The high volume of waste generated in construction necessitates this study on construction waste minimization practices carried out at selected sites in Abuja, Nigeria. This is with a view to minimizing construction waste through the waste hierarchy principles in addition to other site waste management practices. The research studied the practices used in the management of construction material waste in selected construction sites in Abuja through structured questionnaires administered on construction professionals at the selected sites. The study found that there was no specific legislation on the control of construction waste; and construction professionals felt that completion of projects within a time frame, according to specification and within budget was more important than controlling the quantity of waste produced. While these professionals agreed that there was a need to incorporate site waste management practices, they not only lacked implementation guidelines, but their construction organizations did not have existing policies on site waste management as well. The study therefore recommends that waste management practices should be made an integral part of construction project objectives. The concept of waste hierarchy and efficient utilization of construction materials should be backed by legislation. Keywords: Construction waste, waste hierarchy, waste management
