A STUDY OF THE QUALITY OF PROPERTY VALUATION REPORT IN KADUNA METROPOLIS
Estate Management and Valuation Department, Nuhu Bamalli Polytecnic, Zaria
The study examines clients’ perception of the quality of valuation reports in kaduna metropolis with a view to examining their satisfaction level and thus improving on the quality of the valuers’ reports. The survey method employ the use of self administered questionnaire coupled with interview to obtain the relevant data. A total of 15 Banks and 20 estate surveying and valuation firms were studied. Data collected were analyzed using tables and relative importance index. The result of the examination of 18 valuers’ reports in comparison with the standard expected shows that valuers’ reports were meeting the standard. The result also showed 53.3% of the banks are at least satisfied with overall contents of their valuation reports. However the examination of clients’ needs revealed that they would prefer to see more details on the reports. The result shows that “clients demands more information on the larger property market and valuation calculation to convince them on how the valuers arrived at the value; a portion stating the complexity of the market and the position of the property in the market; more emphases on the analytical aspects of the valuation and the estate surveyors and valuers should state how certain they are about the valuation figures”. The study concluded that there should be greater understanding between the clients and estate surveyors with respect to the needs of the clients in the area of valuation reports as well as greater understanding of the limitation of the value figure.

AN ANALYSIS OF OFFICIAL PERSPECTIVES OF DESERTIFICATION IN NIGERIA: IS IT TIME FOR A NEW APPROACH?
UMARU BABA, SAADATU
School of Geography, Earth & Environmental Sciences, University of Birmingham
The Nigerian government considers desertification and land degradation to be the main environmental issues affecting northern Nigerian communities and links it to poverty and food insecurity, and considerable sums of money are targeted towards it. This paper examines official understandings of desertification in at the federal and regional levels by examination of policy documents, and interviews with government officials. The government perspectives seem to follow a crisis view of the environment with a strong emphasis on human causes. This paper argues that a more nuanced view that takes into account the complexity of dryland ecology would be a better driver of policy.

This paper examines the problem of inadequate budgetary allocation to housing development in Nigeria with particular focus 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 vision 20-20-20, Housing Replicability method should be adopted by agencies responsible for housing development for continuing provision of houses for the society.
Keywords: Inadequate Budgetary Allocation, Housing Development, Housing Finance, Budget Estimate, Residential Building.
PARTICULATE MATTER, POISONOUS GASES AND HEAVY METALS GENERATED IN CONSTRUCTION SITES: REVIEW
Civil Engineering Department, Modibbo Adama University of Technology, Yola, Adamawa State.
Dust, Poisonous gases and Particulate Matter emissions can come from a number of sources during construction activities, as well as from off-site vehicles associated with the construction works and on-site machinery (off-road emissions), including both static and non-road mobile machinery. Severe particulate matter pollution in recent years has become a major environmental problem in the world and has received broad interest worldwide. Exposure to particulate matter can aggravate chronic respiratory and cardiovascular diseases, alter host defenses, damage lung tissue, lead to premature death, and possibly contribute to cancer. Particulate matter comes from both human made and natural sources. It contains a range of chemical compounds and the identity of these compounds provides clues to its origin, the knowledge on the extend of air pollutions in construction sites is very important and will help finding solutions to many acute health related diseases contacted as a results of these air pollution at construction sites.

Randomly distributed fiber reinforced soil is among the latest ground improvement techniques in which fiber of desired types and quantity are added in the soil, mixed randomly and laid in position after compaction. Inclusion of randomly distributed fiber makes the soil mass homogeneous and maintains the isotropy in strength. From the available literature, natural fiber reinforcement causes significant improvement in tensile strength, shear strength, and other engineering properties of the soil. However, it is found that little research has been done in the area of assessing the CBR value of Sub-grade soil. This paper therefore presents the results of a laboratory study undertaken to investigate the CBR value of soil reinforced with coir fiber. Soil samples for CBR value tests were prepared at its maximum dry density corresponding to its optimum moisture content in the CBR mould without and with reinforcement. The percentage of coir fiber by dry weight of soil was taken as 0.25%, 0.5%, 0.75% and 1% and corresponding to each fiber content unsoaked and soaked CBR tests were conducted in the laboratory. Tests result indicates that both unsoaked and soaked CBR value of soil increases with the increase in fiber content. It was also observed that increase in CBR value of reinforced soil is substantial at fiber content of 1 %. Thus the significant increase in CBR value of soil due to coir fiber will substantially reduce the thickness of pavement sub-grade.

Toilet options which are acceptable technologically and could be potentially constructed using locally available skills and materials by households and at public spaces paved way for harnessing opportunities in toilet culture, design, and architecture by providing professional solutions. Recent concerns for the professional practice of architects in actualizing open defecation free built environment can never be over emphasized in response to many challenges and issues of transformation from open defecation to open defecation free areas. Also, a healthy nation is central to all physical, social and economic growth. The Nigerian health sector is faced with inadequate sanitary facilities. In most African countries, especially some states in Nigeria have not actually migrated to the next higher level in terms of hygiene as open defecation is still a norm. As a result of the above, this paper is aimed at studying the various transformations in low-cost, but high quality toilet design and construction. The study area under investigation also further discusses issues of immense contribution to sanitation marketing which recommended that government should strictly enforce the law on sanitation marketing towards the attainment of open defecation free environment in Bauchi metropolis.

As solar gains play a vital role in influencing thermal environment in buildings, direct solar gains is the most influential of the three modes of transmission. So, optimising direct solar penetration through equator-facing window would aid in improving thermal performance of buildings during winter. This study seeks to investigate the effects of varying equator-facing window height on horizontal shading device size and the rate of change of radiation beam height (RBH). This study adopted the apparent sun-paths model described in Szokolay (2007) for this analysis. In varying the window height, calculated solar altitude was used to determine the shading device size and corresponding RBH while examining its rate of change. Results show that increase in window height increases the shading device size as well as corresponding RBH. However, the rate of increase of RBH diminishes with increase in window height indicating that optimising direct solar gains does not rely on largest window height. This study focuses on vertical aspect of the equator-facing window which requires only horizontal shading device for optimisation. However, it provides a basis for further research in modelling direct solar gains in buildings, and a useful means for architects to design equator-facing windows.
Keywords: direct solar gains, equator-facing window, façade, radiation beam, shading device.

The realization of chaotic trajectories for the purpose of cryptographic application has always been hampered by fixed points and dynamical degradation due to finite implementation of reals. These shortcomings of the chaos cryptography has been considered and a solution put forward by way of implementing a chaotic map on integer space, the integer space being the traditional home of classical cryptography. An analogue of the logistic map whose domain of implementation is the integer space has been proposed. This map has been shown to avoid the fixed points at parameter values µ ∈ [3.574).

Most poor are excluded in the dynamics of social, political, and economic class struggles in developing countries. The consequences are translating to social fragmentation, disparities and inequalities among citizenries and these undermines social cohesion so much needed for avoiding conflicts and other environmental problems. This review paper, aim at describing the concept and principles of inclusive city planning framework with a view, as a mechanism that can reduces inequality and social tension that is synonymous to poverty. By exploratory review of the global dimension of poverty and the Nigerian perspective, the effects of defective city planning on poverty reduction, the poverty reduction mechanisms and their challenges, the perspective of urban planning system and its challenges, inclusive city planning approach and its operational strategies perspective and case studies of some selected countries successes of implementing inclusive planning. The finding revealed 112 million Nigerians still lives below poverty line, by implication 67.1% live in extreme poverty. The physical planning system largely support spatial segregation and control only. Inclusive planning framework principal strategy is democratic and equity in providing access of basic social services to the masses through participation and engagement of the poor in decision making process. It is therefore, recommended that inclusive planning principal strategy be adopted in re-structuring cities plan in Nigeria to enhance city environments.
