This research paper theoretically underpins the solid waste management practices in Urban Federal Capital City, Abuja as basis for a blueprint towards attaining a clean and healthy urban centre through enhanced and intensified initiative of the local government councils to address waste problems in cooperation with other concerned stakeholders (private sectors and non-government organizations) of the society. In Municipal Solid Waste Management (MSWM) in developing countries five typical problem areas can be identified: – inadequate service coverage; operational inefficiencies of services; limited utilization of recycling activities; inadequate management of non-industrial hazardous waste; and inadequate landfill disposal. This article discusses some of these problem areas in Abuja Urban capital and suggests possible approaches for improving the situation. Emphasis is on the problem of inadequate landfill disposal. Open uncontrolled dumping is still the most common method of solid waste disposal in developing in the Federal Capital – Abuja. Although the environmental consequences are often quite evident because of the health hazards, the problem is seldom dealt with. Reasons for not dealing with the problem are low political priority, inadequate resources allocated, and/or missing know-how regarding alternative solutions for operating and managing a landfill/dump. To improve the current situation, alternative institutional and financial models for disposal activities must be developed and applied. Knowing the costs of waste disposal activities are a prerequisite that enables municipalities to make decisions about their programs with regard to cost minimizing and better planning for the future. The guidelines for management of Urban cities should not be based primarily on the existing requirements of sanitary landfills in Abuja, but should mainly take into account the basically different physical and economic situations prevailing in developing countries. In that respect efforts should also be undertaken to upgrade existing dumpsites and so “aiming” in the long run in the direction of a sanitary landfill

This study aimed at assessing the effectiveness of medical waste management (MWM) in the selected Healthcare facilities (HCFs). The study involved the survey of a descriptive cross-sectional study that assessed seven (7) HCFs in Minna and Bida in Niger State, Nigeria. Five (5) public (A, B, C, E and G) and two (2) private (D and F) HCFs. Data were collected using three instruments: questionnaire, in-depth interviews and field survey. The study revealed that highest percentage (26.5%) of professional cadres were nurses/midwife. Hence, the majority (76.4%) of the study participants involving medical personnel and handlersreported dealing with hazardous medical wastes. This evidenced that medical staff and handlers are mostly considered prone to the potential harmful occupational hazard with high level of risk and burden of transmission of infectious waste that was yield to represent the highest proportion (16.1%) of hazardous medical waste. The present study also established that all the HCFs have the same process of managing their medical waste and deficiencies were found in the adaptation of holistic approaches and current MWM techniques. Most (65.8%) of the existing practices of all operating system prevailed Poor compliance to a set standard. Moreover, the study revealed that the existing practice of general MWM strategies in accordance with the T&C (2005) guidelines at studied sites are mostly classified as operational performance level 0 and 2 which implies that the present management practice for medical waste is ineffective and should not be relied upon to protect human health and environmental integrity.

Sachet water waste disposal is a vast problem that needs to be tackled because of the implications it has on biophysical environment such as soil, vegetation air and water (Toyobo, Oyeleke and Amao, 2013) is. Notwithstanding the benefits accruing from sachet water production and consumption, the indiscriminate disposal of the waste in various undesired sites such as along the streets, gutters, motor parks, schools, markets, homes, and venues of social functions etc. poses a lot of threat on the environment especially on the soils on which farming is done. The sachets are made of non-biodegradable synthetic polyethylene (polythene) which does not decompose in the soil even after many years. The polythene even when subjected to burning produces major known and harmful greenhouse gases (GHGs) like carbon monoxide, nitrous oxide and carbon dioxide (Akunyili, 2003). Almost every nook and cranny in Nigeria is littered with sachet water nylon, known to be pure water, the large volume of which in ordinary parlance, constitutes pollution and termed negative externality or economic bad in economics (Babatunde and Biala, 2010). This is as a result of millions of used sachets being thrown on daily basis onto the streets of virtually every city, town, and village in Nigeria. About 70 percent of Nigerian adults drink at least a sachet of pure water per day resulting in about 50 to 60 million used water-sachets disposed daily across the country (Edoga, et al. 2008)).

The aim of this study is to evaluate major challenges experience in homeownership delivery in federal polytechnic Lafiya, Nasarawa State, Nigeria, with a view to recommend appropriate implementation measures. Homeownership has been considered a crucial phenomenon that requires an in-depth understanding of both theoretical and empirical evidence for a robust policy formulation. The study adopted the use of quantitative design and data were collected through questionnaire survey from academic and non-academic staff of Federal Polytechnic lafiya, Nasarawa state. 400 structured questionnaires were distributed to the staff, the study adopted simple random sampling technique and SPSS software version 22 was used for data analysis and the results were presented in table. The study revealed that the major challenges experience in homeownership were cost of building material, inadequate finance mechanisms, conditions for accessing housing finance and inadequacy of administrative and legislative provisions to the homeowner. However, the least challenges experienced in homeownership in the study area was inadequacy of housing information system. The study concluded that cost of building material, inadequate finance mechanisms, conditions for accessing housing finance and inadequacy of administrative and legislative provisions to the homeowner and they were found to be the high challenges of homeownership in the study area and the least challenges experienced in homeownership in the study area was inadequacy of housing information system. However, it is recommended that the government should be able to control the price of building materials so that an individual can be able to purchase the building materials at subsidise rate and this will address the challenges of personal homeownership. Also, it is recommended that government and the polytechnic management should address the problems of inadequate finance mechanisms by providing special loan or special incentives to staff and this will make more staff to have personal homes. The study recommended that there is a need for the policy makers to increase the number of staff quarters in the polytechnic to enable more staff to access the housing in the institution.

Most of the indigenous architecture are usually made of local construction technology and local construction method which shows a careful thought in this style of building, the choice of materials is readily available and fits our tropical climate. Some of the popular and noticeable architecture are the Hausa, Igbo and Yoruba – the three popular tribes in Nigeria. Due to the current trend of the economic recession, the initiation of this work looks primarily into the concept of providing a low cost home and food security. Architecture and green economy resources showcase buildings that produce plants and animals. The organic technology resources here focus on the production of different high value crops like tomatoes, vegetables, maize, and beans. Other components of the integrated farm include chicken (native and exotic), cow, goat and ram raising with fish culture. The approaches to fertilizer uses, pests and diseases control is purely organic in nature, in which, raw materials come from available farm wastes, indigenous plants and crops that are easily found and grown within the area or nearby areas. However, the need for design, construction and management of such two in one building facilities are too much of a heavy burden to bear due to some circumstances beyond the control of the masses. Hence, the work is aimed at studying the various concepts in achieving sustainable green economy development in terms of how to obtain and use architectural innovations, waste to wealth initiatives, constructions, cutting-edge technologies, principles, laws and regulations among others. As a result of the above, this paper revisits as well as appraises the issues and challenges of architecture and integrated green economy resources for positive implementation and benefits for the masses.

Medical waste management is a complex subject that affects people all around the world. Mismanagement and ignorance of its have resulted in a variety of environmental issues in developing countries especially in many urban areas with high numbers of health centers. This study assessed the current medical waste management practices in selected secondary and tertiary healthcare facilities in Niger State, Nigeria. A semi- questionnaire, self-administered questionnaire, focus group discussions (FGD), field observations and descriptive analysis were used. The samples for this study comprised of healthcare workers, key ministries and residents near healthcare centers. The results showed that about 1285(77.8%) of the respondents agreed that, only syringes and needles waste and human body parts and placentas wastes were segregated. 1616 respondents, equivalent to (97.7 %) agreed that there were non-availability of labelling and colour coding of hospitals wastes, neither was there segregation of hazardous waste. 100% of all the selected hospitals in this study used open surface burning and open fire pits were the major methods of treatment and disposal practices. These could contaminate the environment and affected their well-being and health. There should be proper management of medical wastes through adequate retraining of staff, provision of colour coded bins and global best waste treatment before final disposal.

CLIENTS’ AWARENESS OF THE USE OF VALUATION STANDARDS IN VALUERS’ SERVICE DELIVERY IN NIGERIA
YUSUF L. GAMBO
Department of Estate Management, University of Jos
The paper examines the level of clients’ awareness of the application of valuation standards in valuers’ service delivery with a view to understanding clients’ appreciation of the quality of service delivery by valuers. All the 21 commercial banks were considered for the study but only 19 responded making over 90% response rate. Data was analyzed using simple frequency tables and percentages. The study reveals that clients are completely unaware of other national and regional valuation standard manuals and merely heard of Nigeria’s version of the standards. Banks always request for forced sale value from valuers as basis for mortgage valuation. It was also found that clients cast doubt over valuation carried out by valuers, and sometimes reject valuers’ reports. As a result, banks sometimes do assign more than one valuer to value the same property. The paper recommends for stakeholders’ workshops to be initiated by valuers’ professional bodies and the consumers of valuation report on how these standards apply in practice. Valuers should be stating in clear terms which standard they are adopting in their service delivery and reporting. The clients should be informed what duty of care they owe the professional valuers in their professional assignment. The clients should ensure valuation carried out by professional valuers meet the provision of the standards. Valuers and their clients should depart from culture of doing next to best thing and embrace the best practices for efficient functioning of the professional environment.

Department of Estate Management and Valuation, Federal University of Technology, Minna, Niger State, Nigeria
Property tax revenue constitutes less than 4% of all tax revenues in developing countries, and averages 0.42% of Gross Domestic Product (GDP) of developing countries respectively. Although property tax has great potentials yet it is faced with the problem of ineffectiveness and unreliability induced by weak administration and technical limitation which seriously limit its ability to generate adequate revenue. This study assessed the administration and management of property rating in Minna with a view to proffering a sustainable property rating administration. Cluster sampling technique was adopted for selection of three (3) neighbourhoods from unplanned and planned areas each. The housing units was sampled using simple random sampling technique. A sample size of 399 was used. Weighted Average () and Relative importance Index (RII) were used to examine property rating trend, management and challenges in Minna. Findings revealed that property rating is not a popular activity in Minna because a large number of respondents are grossly unaware of the process. Result shows that only about 28% of the respondents have paid for property rating before, out of the 52% who are aware of it. However, majority (57.2%) of the respondents have not been issued demand notice before. The trend in property rates of Minna from 2010 to 2019 shows a constant increase from 2010 to 2017. The following recommendations are proffered to achieve the set objectives of the study; the rating authority need to create awareness to the general public of the need to pay for property rating. There should be transparency in declaring revenues and the use of the revenue to the public. This will help residents develop faith in the process and increase their willingness to contribute. Rating authority should be up and doing about their activity in issuing demand notices to residents and develop an updated data base for effectiveness and efficiency in discharging their duties.

A thorough revamp of airport facilities management practice in Nigeria is highly vital and important for airport management. In light of this, this research developed a holistic approach for managing airport facilities in Nigeria. Surveys and on-site observations of airport facility management practices in Lagos Airport were used to gather the study’s data. According to the study, the majority of respondents are from a variety of professions, including engineers, Estate Surveyors, and Valuers amongst others. Additionally, the study found that the primary airport facility management strategy was a hybrid approach that combined in-house and outsourced facility management tactics. The study also provided a framework for enhancing airport facilities management practices in Nigeria and underlined the significance of a Facility Manager as the principal overseer of all airport operations. The study also made a call for the recognition and appointment of Estate Surveyors and Valuers as the Airport Facility Manager who would be responsible for ensuring the smooth, effective and efficient operation of the airport’s services and facilities only after completing the required training. Therefore, it was recommended that the Federal Airport Authority of Nigeria (FAAN), the Nigerian Institution of Estate Surveyors and Valuers (NIESV), the Estate Surveyors and Valuers Registration Board of Nigeria (ESVARBON) and other pertinent agencies should support the active participation of Estate Surveyors and Valuers in Airport Facility Management (AFM) and work to improve Airport Facility Management practice in Nigeria.

Sodium Hydroxide (NaOH) is an alkaline activator mixed with agro-industrial waste to produce a paste capable of setting and harden within reasonably short period of time. Alarming levels of green gas emission from (PC) Portland cement production and low setting time of millet Husk Ash (MHA) – Calcium Carbide Waste (CCW) products (Mortar and Concrete) has necessitated into utilizing this alkaline activator. MHA – an agricultural waste and CCW – is an industrial waste. Different combination proportions (40:60, 45:55, 50:50) of MHA/CCW were then activated with varied molarities of NaOH solution (5M, 10M, 15M and 20M). The mortar was produced at 1:3 binder / sand (B/S) and 0.5 water / binder (W/B) examined the effect of NaOH for binding, hydration, strength development and water absorption at varied curing age ( 3, 7, 14, 28 and 56) respectively in accordance to BSEN 196 – 1:2016. The result revealed Alkali-activated Millet Husk Ash-Calcium Carbide Waste (AAMHA-CCW) samples test exhibit increased performance for both properties examined with increased NaOH molarities up to 15M for all combination proportions. At 15M of NaOH (45/55 MHA-CCW) exhibit similar fresh properties (Water demand, setting times and soundness), compressive strength and water absorption as the control (PC) based mortar.

This study is to investigate Bruno Taut’s contributions and philosophy as one of the leading lights and father of modern/architecture. It also x-ray who an architect, his role and struggle in natural development. Studies and investigations carried out revealed his immeasurable and un-quantified contributions to the modern Architecture in the use of glass and color in architecture as manifested in his work – The Glass Pavilion (1914) and House 19 in his exhibition; and also in urban planning and housing Estate development (Box Paint Estate).His contributions as an architect, author, educator,(Professor of Architecture), a public servant have in no small measure accorded him a place of pride among the few architects with wide experience in all spheres of life. His foreign trips also contributed to his exposure in architecture in other domains with cultural differences as noted in the designs of his own house with Japanese and Turkish influence. He will be remembered as an apostle of color and glass, although he was criticized for his work as well as his involvement in art décor which made many portray him as an artist. However, this has come to portray that architects as jack of all trades and master of design has much relevance in this contemporary time.

This study evaluated and weighed the spatio-temporal dynamics of urban sprawl in Oyo town. Sprawl in Nigeria is a menace that is very obvious with various unsustainable impacts, presenting concern for ecofriendly sustainability. Landsat images of years 2003, 2013 and 2021 were classified to produce land use land cover maps. Urban sprawl and expansion were analyzed using post-classification transformation finding and spatial metrics methods, respectively. The outputs revealed built-up area grew by 0.40% during the first period (2003-2013) studied, and 14.25% during the second period (2013-2021). While non-built-up encompass an area of 4640.12 km2 (97.48% of total area), and it decreased to 4620.01 km2 (97.06%) in 2013, and 3941.05 km2 (82.80%) in 2021. During the third period (2003-2021), built-up area enlarged from 1.68% of the total area in 2003 to 16.33% in 2021, indicating a great change of 14.65% in built-up area between year 2003 and 2021. The analysis further revealed a growth coefficient of 2.424%, which indicated that Oyo town is experiencing urban sprawl. According to the urban expansion intensity index scores of 0.814%, Oyo recorded a relatively medium speed urban expansion between year 2003 and 2021. Urban sprawl in Oyo has caused land degradation, loss of vegetation cover, loss of natural habitat, and contamination of surface water amongst other things. In view of the vital part played by vegetation as a carbon sink, policy makers are requested to strictly enforce laws to achieve maximum control over urban growth, development and sprawl within Oyo town.

The paper examines the effects of solid waste on drainages and roads in Barama ward of Mubi North local government area. The study was based on the methods of waste disposal, the effects on the area and the steps to be taken in order to control hazards it may likely pose on Barama. Survey design was employed where secondary and primary sources of data collected were adopted. Structured questionnaire and personal observation were used. 80 questionnaires were designed and administered to residents that were selected through systematic random sampling method in the area to collect primary data, while information were gathered from textbooks, downloaded websites, materials/ magazines for secondary data. The field data gathered was analyzed using frequency counts and simple percentage methods. The results of the findings were presented on tables. The study however revealed that reckless solid waste dumping in Barama is as a result of absence of official refuse dump in the neighborhood. This therefore makes people to dump refuse indiscriminately thereby blocking drainages and littering the surrounding which, give an ugly picture of the area. This situation can likely affect the air, the land, the ground water and other resources. In view of the above, recommendations and proposals were made: six (6) refuse dumps were suggested to be sited as shown on the map of the area. People should be educated on how to exhibit good attitudes towards the environment and new laws should be enacted and existing ones revisited and enforced strictly on the need to have a healthy environment. Government and residents should join hands to improve the drainage conditions in the area.

Building account for a sizeable amount of total energy consumption and total greenhouse gas emissions around the world. Green building has consequently emerged as innovative building concept to lessen the environmental impact of these buildings. The aim of the study is to assess professionals’ perception on the cost benefits of green building practice and its adoption for construction projects in kogi state. The objectives of the study are as follows: to identify the most preferred cost benefits of green building practice and to assess professionals’ perception on the cost benefits of green building practice and its adoption for construction projects in the study area. A structured questionnaire was used to collect information from various respondents who were construction professionals. The survey was conducted in kogi state using random sampling techniques were used to select one hundred and thirty (130) respondents out of which (95) of them were suitable for analysis, which represent a potential responses rate of seventy three percent (73%) of the total. The data were analyzed using simple percentile and mean item score. The research shows that respondents have a low level awareness of green building in general. The finding revealed that green features that would be mostly adopted by professionals include: careful orientation and low energy, lighting design, the uses of renewable energy e.g maximum use of natural day lightening and the uses of energy efficient and eco – friendly equipment. In conclusion the study advocated for increased sensitization of benefits of green building among built environment practitioners in such a way to deepen the adoption of green building practice in the study area. The study recommend that professional bodies should train and educate their members on the importance of green building so as to incorporate the lofty practice in their daily practice.
