Abstract

As a result of the necessity and quest to have own shelter emanating mainly from the ever rising accommodation rent cost, there has been a great thrust by poor urban dwellers, low and middle income earners to move to the urban fringes and start their shelter – somehow. The paucity of funds engenders the practice of cutting expenditure to the extent and effect that several building materials and methods employed are unconventional, deleterious and detrimental to the health, safety and security of such owners and users. This study investigated the extent and depth of this practice in a selected area (Gamajigo community) an urban fringe of the city of Jos, in North Central Nigeria with a view to proffering solution to the anomalous materials and methods. The methodology employed involved first of all identifying buildings that were in active construction process, investigating the methods and materials applied in their construction. Thereafter, knowledge of Architectural theory and practice was applied to propose better and more wholesome materials and methods. The findings were that the use of several cost saving measures (materials and methods) which had detrimental consequences were very pervasive. The study also found that in as much as cost saving measures were desirable to attain a low cost, low budget housing, there were some incontrovertible fundamental costs that building owners should not run away from bearing. The study therefore proffered better ways of attaining cost saving measures that would not jeopardizing health, safety and security of the owners or occupants. This study was significant and contributed to knowledge in that by adhering to the provisions and suggestions of this study, low cost housing could be attained by the urban low and middle income earners through self – help methods without jeopardizing health, safety and security of the owners of such dwellings. The study also has the promise of enhancing the durability of such structures coupled with the additional benefit of maintaining minimal expenditure for housing procurement.

Abstract

This paper highlighted the significant of useful and effective national land policy for social justice and economic prosperity in Nigeria. Due to the importance of land and landed property to nation building. National land policies are cardinal principles for any meaningful development for human race. Good national land policy is an indication of developments and advancements in terms of land administration and management. Land as a factor of production, in many respects it needs proper management. Land is a one of main asset to urban and rural poor. Criterion for many advancements has an impact with the efficient mechanisms for land policy implementation. Different approach to national development in many spheres of nations struggle is irrelevant when land policies are not in efficient. Land tenure before and after colonial masters were reviewed to ascertain the development of different land reforms that took place in Nigeria. National land policy and economic growth relationship was established within the framework of national economic development. Economic growth and stability are the results of national land policies.  Issues bothering access and control over land was stated. Unemployment and job creation were stated that emanates from poor land policies. It was recommended that national land policy should be employed for national security and development. Issues related to access to land were incorporated to the proper land policy. The significant of national land policies cannot be over emphasised, because of it is paramount for egalitarian society. It is recommended to the concerned government agencies to reflect on importance of national land policies. And regularly inspection of statutory documents related to land policies should be revisiting for time interval. It is also recommended that public enlightenment and sensitisation should be encourage to help the citizen have knowledge on issues related to land. The study would be of immense benefit and points of direction for future researches.

Abstract

This paper attempt to draw attention to some of the problems and highlighted the importance of Housing delivery to the individual and the economy as a whole titled the involvement of private sector in reducing housing deficit through the land acquisition and compensation in Nigeria. As Housing is one of basic necessities of life that determines social, physical and psychological well-being of human. In microeconomic terms housing is a significant component of household consumption and savings. Today, the unimaginably high demand for housing is on the increase on daily basis in our urban centres and due to the incapability of the federal, the state and the local governments in providing housing to the populace observed by the private developers, are tends to contribute to a large proportion, the entire housing stock in the country. The participation of the private sector in housing delivery provide direct use by their staff and for rental use or outright sale to the public. Unarguably, the private sector has been more efficient and reliable in the production of housing than the public sector. The relationship exists between land and economic development as a result of the significance of land. This result in the reforms of a legal and regulatory framework to support the private section participation, the legal framework for our land system remains unchanged and much needed activity in the real estate sector is yet to be felt. It is however hoped that Government would as a matter of urgency make the necessary reforms needed to support the housing sector’s development. Private individuals are also to partner with the government in ensuring a formidable partnership and sustainable housing delivery.

Abstract

Sick building syndrome has been described by The World Health Organization, WHO describes as set of non-specific symptoms occurring in a particular building and not caused by a specific illness such as allergy or infection. The sick building syndrome is a global occurrence given that the contributory factors emanate in buildings. Sick building syndrome has no specific building to which it is accustomed to. This implies that the symptoms can occur in residential, commercial, educational as well as industrial buildings as long as the contributory factors are present. However, this assessment of sick building syndrome was carried out on residential properties in Kpakungu, Bosso Estate and Zarumai Quarters in Minna in order to determine the level of occurrence of the causes and symptoms of sick building syndrome and establish a relationship between the causes and symptoms in the selected neighbourhoods. The sample size for the study is 504, comprising of Kpakungu (298), Bosso Estate (184) and Zarumai Quarters (22). The methods adopted for the analysis of data include descriptive analysis, the use of weighted mean as well as inferential statistics (Karl Pearson’s Product Moment of correlation). The study shows that the symptoms of sick building syndrome such as headache, stuffy nose, runny nose and tiredness are reported in the three neighbourhoods at differing levels. This is as a result of the various contributory factors identified such as noise, dust, inadequate ventilation and poor property maintenance. The correlation coefficient result shows that the coefficient (r) of 0.989 means there’s a very high positive correlation between the identified causes and reported symptoms of sick building syndrome in the three selected neighbourhoods in Minna.

Abstract

The sustainability of any construction project depends greatly on the accuracy of cost estimates to meet time and budget. Despite these concerns, the accuracy of construction labour cost estimate in Nigeria still remains unclear. Hence, this study aimed to identify the factors affecting accuracy of labour cost estimation towards sustainable development. The objectives of the study include to identify the factors and evaluate the degree of agreement to which these factors are significant from construction contractors and consultants’ perspectives. A sample of 100 contractors and consultants each were randomly selected from the list of registered contractors and consultants by the Bureau of Public Procurement (BPP) which gives a total number of 200 questionnaires distributed, out of which the responses rates received were 80 (80%) each for the contractors and consultants. Data analysis include Relative Importance Index (RII) for ranking comparison among the contractors and consultants on a scale range from 1-5 for rating their responses. Kendall’s coefficient of concordance was used to evaluate the degree of agreement between contractors and consultants’ viewpoints related to the ranking of each of the factors. The results of RII revealed that the five topmost factors affecting accuracy of labour cost estimates are experience in pricing construction project, accuracy and reliability of cost information, clear and detailed drawings and specifications, site constraints and perception of the importance of labour cost estimates. The results of Kendall’s coefficient indicates a significant and strong degree of agreement between contractors and consultants towards ranking of the factors affecting accuracy of labour cost estimates. The findings are focused to provide the best way to achieve accurate labour cost estimates for a sustainable project. It was recommended that for an accurate labour cost estimates, the estimator should take into consideration these factors at the inception stage of cost estimation.

Abstract

Urban household farming is an important source of food throughout the urban developing world and is a critical food security strategy for poor urban households. The challenges to this system of agriculture remain persistent poverty and rapid urbanization brought by significant numbers of poor and hungry people into the cities. Therefore, this study examine the impact of urban household farming on food security in Kuje Area Council, FCT, Nigeria. The sources of data for this study include questionnaire administration and field survey. The method of data analysis was descriptive statistics. The result revealed that production of food ranked the highest with 31.4% of the sample population, saving money ranked second with 29.2%, increased balanced diet ranked third with 25.4% and employment creation ranked the least with 14.0% of the sample population in the study area. This implies that the major role of urban household farming on food security is food production which enhance food security. The study also revealed that the low density areas in the study area ranked the least in level of engagement of urban agriculture with 21.4% of the sample population; medium density areas ranked the highest with 53.7% and high density areas ranked second with 24.9% of the sample population. This implies medium density areas were more engagement in urban agriculture in the study area because they have better access to land and resources to farm. It’s therefore recommended that there is need to integrate household farming into urban planning by establishing a greenbelt zone to halt urban development activities especially in cities like Abuja.

Abstract

This study investigated how learning, teaching and working spaces within the school of management studies of Nuhu Bamalli Polytechnic, Zaria are being utilized with the aim of analyzing the situation and developing various space utilization and management techniques which can prove useful for purposes of capital planning in the school and the polytechnic at large. The population of the study was 110 staff and a stratified random sampling approach was adopted to get a sample size of 26 for the study. The instruments used to get information where observations, interviews and questionnaires. Descriptive analysis of frequencies, percentages and mean ratings were used to answer the research questions. The major findings showed that there was a great difference between staff strength, student population and available facilities. It further showed that staff were not satisfied with their working spaces and some classrooms were not fully utilized within the week because of preferred time or rescheduled time and preferred days for lecture. Therefore, the study recommended that a few large classrooms or an auditorium should be provided to cater for the very large class sizes to ease congestions and also save teaching time and costs. Additional office spaces are required which can be flexible in the office space arrangement so as to accommodate the increase or decrease in staff strength. Furthermore, allocation of teaching spaces for classes should be based on class size, course requirements in respect of teaching materials, equipment and furniture needs. This will make the instructional rooms to be used more often by different groups of learners based on their needs.

Abstract

This paper examines the problem of inadequate budgetary allocation to housing development in Nigeria with particular focus on the budget of Kwara State in the last 10years. Secondary data were collected from Kwara State Ministry of Planning and Economic Development through their yearly financial reports. The total estimate for the yearly budget and amount allocated to housing were collected and analyzed. The findings were presented in tables, showing the budget estimates and percentage of amount allocated to housing. Among the major findings is that low priority was accorded to housing development through the budgetary allocation to housing, there is no political will to carryout housing development, less than one percent of the total state budget is allocated to housing, lack of affordable accommodation led to increase in rent by private developers. Each state government is encouraged to allocate enough fund for housing development in the state, government should have political will to develop housing sector to achieve “post” vision 20-20-20 in the near future. Housing Replicability method should be adopted by agencies responsible for housing development for continuing provision of houses for the society.

Abstract

The need for environmental sustainability in the increasing population and rapid urban growth cannot be over emphasized in view of the fact that environmental sustainability is said to be one of the biggest challenges and the most important targets of the present times. Sustainability as a concept is the ability to sustain or support from any kind of irreversible negative environmental impacts or effects. The goal of urban planning is to guide and manage for orderly development of urban, suburban and rural areas with the interest of sustaining the environment.  The activities of urban planning practice such as land use planning, preparation of development plans of different types, as well as preparation of planning schemes/layouts contributes to attaining environmental sustainability. The qualitative approach was adopted for the study. The data for the study were mainly from secondary sources. Analytical desktop approach was used in scrutinizing the materials collected. The finding of the study indicated that urban planning through existing urban planning laws, ordinances, standards and policies to some extent has contributed to environmental sustainability through prevention of environmental challenges and mitigating natural hazards. Contraventions of planning laws, unguided development and political influence are some of the major constraints to effective delivery of urban planning mandates in Nigeria. The way forward to achieving environmental sustainability is by strict adherence to planning regulations and standards for urban development, integrating environmental concern in urban planning design and engaging the citizen in planning decision making.

Abstract

This study analyzed the Spatial Distribution of Filling Stations and Vulnerability to Fire Hazard in Kaduna South Local Government Area, Kaduna State. The methods includes data used for the names and addresses of filling stations in the study area as well as guidelines and staSndards for setting up a filling station was obtained from the Department of Petroleum Resource (DPR) and verified on site, while their coordinates were obtained by the use of hand-held Global Positioning System receiver (Germin 76S). These were plotted on a base map using ArcGIS 10.1. Maps are used to determine the locations, distribution, compliance to standard and densities (concentration) of the filling stations. The result of the study shows that the areas with the highest concentration of filling stations are in Makere and Kurmin Mashi and about 82% of the filling stations do not meet regulatory requirements for proximity to major roads. In addition, with the high population density in the study area, about 52 out of 93 filling stations are located within residential areas, which have vulnerable to fire hazard. It was recommended that both government and regulatory institutions should implement the concept of sustainable urban growth in order to balance land and urban development. Also investors must understand that investments are meant for public good and not the other way round. Therefore the general public should always insist on respect for their safety and lives by making sure that utilities or developments in their vicinity conform to safety regulations and development standards.

Department of Architecture, Nuhu Bamalli Polytechnic, Zaria, Kaduna State, Nigeria.

 

Abstract

The activities of the building industry have been a major source of environmental degradation and an impediment to the sustainable agenda. Because of this, there is a global call upon the building sector to improve the manner in which it operates and   going “green” has emerged as the paradigm. Most nations especially the developed ones have aligned to this agenda and Nigeria seems to be lagging behind. This paper therefore highlights what green architecture is all about and the circumstances surrounding issues of green architecture in Nigeria. A descriptive and quantitative research method was carried out to sample opinions of 38 built environment stakeholders on the issues surrounding green architecture in the country. The findings show that insufficient information on green products; inadequate training of industry professionals on sustainable design methods and lack of enforceable policies by government and industry professional bodies were major causes of the challenges. The study therefore recommends a clear definition of enforceable policies; a retraining and reorientation of built environment professionals; public awareness on the need for green building amongst others.

Abstract

A large amount of solid wastes is generated from homes. Household waste accounts for major amount of solid rubbish, some are reusable and others non-reusable. The generation of waste is an inevitable part of human activity. About 85.8% of Nigerian waste is generated by households of this about two thirds of wastes are dumped indiscriminately on the streets and in the drains thus posing serious environmental health hazards. Every household activity results in solid waste generation and it is becoming more and more acute in the current technology- driven days.  The composition and generation rate of domestic solid waste in Chikun local government area, Kaduna state, Nigeria was assessed by the use of data on domestic waste composition and quantity of domestic waste generation sourced through field and questionnaire survey. The study was conducted on 396 respondents which were selected using systematic random sampling from the five urban wards in Chikun LGA. Data were analysed descriptively. The results from the study was then applied to determine the waste management option for the domestic waste in Chikun LGA.  Results showed that 76% of the waste generated in Chikun LGA were biodegradables which are mostly vegetables and food waste which weighed 1106.7kg and 542.9kg respectively. The average domestic waste generations in Chikun LGA are 455.8kg/day, 1.2kg/household/day, and 0.66kg/capita/day. The average bulk density was found to be 1484.8kg/m3. The high percentage of the biodegradable waste and amount of waste in general calls for an urgent attention as this could lead to adverse health effects. Based on the results of this study, it was recommended that an integrated solid waste management system consisting of incineration with energy recovery process, composting of household waste and enhanced recycling and sanitary landfill be established for the people of Chikun LGA, Kaduna State.

Abstract

This study provides a pilot investigation into the assessment of traffic flow and management measures at selected road intersections in Ilorin metropolis. The study relies on both secondary and primary data for achievement of the aim of the study. A total number of 360 copies of questionnaires were administered using a purposive sampling technique. Three indices were developed for this study; these include Causes of Traffic bottleneck (CTBI), Effect of Traffic bottleneck (ETBI) and Effectiveness of Traffic Control Measures (ETCMI). The study established that Murtala/Amilegbe junction recorded the highest volume of traffic among the studied road intersections with 5829 vph and 5898 vph for morning and afternoon peaks respectively while motorcycles recorded highest average vehicle type (1701 vehicles) at the sampled junctions. The study observed that increase in population has the highest CTBI in the city with CTBI value of 4.06 and identified Lateness to work as the major effect posed by traffic congestion across the study area with ETBI value of 4.31. The study also revealed that Availability of law enforce agents is effective (ETCMI= 4.54). The study recommended Provision of CCTV at strategic locations and some problematic intersections in the City, encouragement of public/private partnership investment and operation of mass transit and provision of proper signalization i.e functional Electronically Control Traffic Device among others in the study area.

Keywords:  Transportation, Intersection, Traffic Flow, congestion, Traffic Control Measure, accessibility.

Abstract

The migration from rural to urban areas is an important part of the urbanization process in Damaturu town. Even though it has been the focus of abundant research over the past five decades, some key policy questions have not found clear answers yet. To what extent is rural-urban migration a desirable phenomenon and under what circumstances?  Should governments intervene and if so with what types of interventions? What should be their policy objectives? To shed light on these important issues, I survey the existing theoretical models and their conflicting policy implications, and discuss the policies that may be justified based on recent relevant empirical studies. A key limitation is that much of the empirical literature does not provide structural tests of the theoretical models, but only provides partial findings that can support or invalidate intuitions and in that sense support or invalidate the policy implications of the models. My broad assessment of the literature is that migration can be beneficial or at least be turned into a beneficial phenomenon, so that in general migration restrictions are not desirable. I also identify some data issues and research topics which merit further investigation. With the recent development of Damaturu town, the town witness a high rate of development and population growth. Reduction in the number of the migrating groups because of hardship and warfare, Changes in physical characteristic of people Encountered through inter-marriage, Changes in cultural characteristic of people encountered, linguistic changes, and also affected by cultural adaptation of the people in the study area. This research aimed to examine the geographical study of rural-urban migration in Damaturu town and find out possible solution to it. At the end of this research work findings revealed that”. The young adults in the rural areas are migrate to urban area in order to improve their economic conditions. They (young adults) are pushed out from their origin (rural) because of the relative non-availability of employment opportunities. The research found that the desire for gainful employment is the ultimate factor behind rural-urban migration. However other less compelling motivator such as the desire to enjoy the social amenities service likes electricity, good roads, and good drinking water. Rural-urban migration is highly selective in terms of age, sex, educations and occupations. Furthermore, the study found that younger adult in rural areas is the most dominates migratory and are more migratory than the old age. While men migrate more than women. Rural-urban migrations are selective in terms of educations because environment requires one form of formal educations or the other and the necessary skill to do urban jobs.
