Item Afonja, A.A.(Department of Urban and Regional Planning, Faculty of Environmental Technology, Federal University of Technology, Akure., 2023-12-16) Ola, A.B.; Wahab, W.B.The study explores the impact of seasonal changes on the types and volume of waste handled by informal waste collectors (IWCs) in Ibadan, Nigeria. The research involved 253 IWCs who were surveyed using questionnaires and field observations. The results showed that the types and volume of waste collected varied from season to season. In the dry season, patronage was reduced by 25% due to less waste volume and increased burning. This reduced income by 25% on average. This raises concerns about job security for IWCs and the impact of increased burning on the atmosphere, leading to global warming. The study recommends financial and technical assistance from government or non-governmental organisations to help IWCs establish small waste merchandising businesses to cope with low patronage. This could help mitigate the adverse effects of seasonal changes on IWCs' operations.Item Anthropogenic Activities and their Impacts on Biodiversity Survival in Ifelodun Local Government Area, Kwara State, Nigeria(Department of Surveying and Geoinformatics, University of Ilorin, Ilorin, 2020-08-03) Ola, A.B.; Adewale, Y.Y.; Raheem, W.A.; Afonja, A.A.Biodiversity plays a significant role in the socio-economic development of man. Therefore, careful use of biodiversity is an essential requirement for sustained global development. However, available data points to a high rate of biodiversity loss especially in developing countries which has been attributed to a combination of human-induced factors, including rising demand for and consumption of natural resources. This paper identifies those human activities that result in irreversible loss of biodiversity using the Ifelodun Local Government Area of Kwara State as an example. A structured questionnaire containing information on the people’s activities influencing biodiversity loss, the effects of biodiversity loss, and socio-economic characteristics among other questions were randomly administered to 250 residents of the Local Government Area. Residents Agreement Index (RAI), descriptive statistics (frequencies and percentages) and, regression analysis were used to explain the causes and effects of biodiversity loss. Ten major activities were identified to be influencing irreversible biodiversity loss. They are, cattle rearing (1.21), logging (0.89), road construction (0.81), culture (0.79) and herb harvesting (0.59), poaching (-0.69), farming (-0.61), Industrial activities (-1.59), energy generation (-1.32) and settlement development (-0.05). The effects of biodiversity loss include poor crop yield (43.2%), soil erosion (31%), a threat of desertification (12%), reduction in the number of wildlife (9.6%), reduction in timber production (4.2%). The results of the regression analysis show that biodiversity loss is a function of the socio- economic characteristics of people. The paper concluded that though the socio-economic development of a society is attached to its biodiversity exploitation, careful, diligent, and sustainable use of these resources is required.Item Assessment of Solid Waste Management in Selected Markets in Ilorin, Nigeria(Ladoke Akintola University of Technology Press, Ogbomoso, Nigeria, 2020) Ola, A.B.; Raheem, W.A.; Raheem, W.M.; Ibrahim, R.Item The Dynamics of Land use and Land Cover Change in Non-Costal Town of Giyani, Limpopo, South Africa(Department of Urban and Regional Planning, Benue State University, Makurdi, 2021) Jimoh, M.Y.; Ola, A.B.; Raheem, W.M.; Suleiman, A.R.; Raheem, W.A.Against the background of that land is considered not only as an essential means of production but also as a basis of human existence, its availability and accessibility requires adequate research attention. It is on this conviction that this study seeks to model the patterns, rate as well as identify the consequences of land modification in Giyani town of South Africa over the last 30 years in order to provide informed sustainable land use management policies and programmes. The study used a supervised classification method for geospatial analysis of available LandSat imageries for 1987, 1997, 2007 and 2017 to analyze the changes in land cover in Giyani using available imageries in Bands. ArcGIS 10.3 software and raster calculator tool to produce change detection maps. Land Consumption Rate and Absorption Coefficient were adopted to respectively measure land consumption by each member of the community and change of urban land consumption. The results were overlaid to obtain a visual representation of the area/extent of changes that occurred over time. The result shows that 781.9ha of vegetation was transformed between 1987 and 2017, this was largely informed by the increased demand for firewood and material for construction, construction of infrastructure, government offices etc. Built-up areas increased in its coverage to about 919.44ha within the three decades (1987-2017). Due to the expansion of the town to the hinterland, bare land was consumed by about 672.87ha within same period with 0.06 LRC in 2017 and 0.09 LAC between 2007 and 2017. The paper underscored vertical growth (smart-city growth concept), while promoting tree planting among Giyani residents to prevent wanton modification.Item Effective Management of Storm water in Ibeju–Lekki Local Government Area of Lagos State, Nigeri(Department of Civil Engineering, Ladoke Akintola University of Technology, Ogbomoso, 2020) Raheem, W.M.; Jimoh, M.Y.; Ola, A.B.; Raheem, W.A.; Suleiman, A.R.; Ibrahim, M.In recent years, many cities and rural areas are facing frequent waterlogging, run-of pollution, huge loss of resourceful rainwater, damaged ecosystem and many more rain water related problems. In regional perspective, how to construct a sustainable storm water management measures have been presented as an important issue in many cities and urban agglomeration in Nigeria. Ibeju Lekki area is usually faced with the problem of rain water leading to incessant flooding. This study therefore assesses storm water management in Ibeju-Lekki Area, Lagos state. The research employs a random sampling technique in selecting 204 (0.07 ) respondents for questionnaire administration. Descriptive and inferential statistical tools were employed in the analysis of the data. Pearson product moment correlation was used to test the relationship between the gradient analysis and vulnerability to runoff of Ibeju-Lekki. Also, the slope analysis of the study area was carried out using slope calculation. Findings revealed that natural green space, public parks and gardens and drainage system were the most available storm water management infrastructure in the area. The result of correlation analysis with r = 0.971 shows a strong positive correlation between gradient and vulnerability to runoff . The study concluded that physical planning policies such as thorough monitoring of building plan before approval and institution of effective development control agencies among others should be put in place to ensure proper management of storm water in Ibeju-Lekki local government area of Lagos StateItem Evaluation of On-Street Parking on Traffic Flow in Ilorin Central Business District, Ilorin, Nigeria(Faculty of Environmental Sciences, Nasarawa State University, Keffi, 2021) Suleiman, A.R.; Raheem, W.M.; Ola, A.B.; Raheem, W.A.; Jimoh, M.Y.; Oladimeji, S.B.This Study evaluates on-street parking in Ilorin Central Business District (CBD), Ilorin, Kwara State. It examined the on-street vehicular parking mode and its impact on flow of traffic in the CBD. The study adopted a survey research design using the primary and secondary data sources. A sample frame of 4,543 respondents was determined through parking volumetric count that was conducted between 7:00am to 7:00pm. Questionnaire was administered to 354 motorists who parked their vehicles on the street, using accidental sampling techniques to elicit information on parking characteristics. All the six major roadways that criss-crossed the CBD were all selected for the study. Descriptive statistics tools was used to analyse the data while vehicle to capacity ratio was used to evaluate the impact of on-street parking on traffic flow. The study revealed that 57.9% of the respondents’ vehicles were parked on the street for the purpose of business and work. Further finding indicated that 61.4% of the motorists parked on the road curb because of inadequate or lack of off-street parking facilities in the city’s CBD. Traffic flow was stable in the four major roadways selected with the exception of Ibrahim Taiwo Road where traffic flow was not stable and queues developed rapidly as this contributed to traffic congestion along the road corridor. The paper recommends among others the provision of adequate and designated on-street and off-street parking facilities, regulation of parking by introducing park and pay to discourage on-street parking.Item Evaluation of On-Street Parking on Traffic Flow in Ilorin Central Business District, Ilorin, Nigeria(Faculty of Environmental Sciences, Nasarawa State University, Keffi, Nigeria., 2021-06) Suleiman, A.R.; Raheem, W.M.; Ola, A.B.; Jimoh, M.Y.; Oladimeji, S.O.This Study evaluates on-street parking in Ilorin Central Business District (CBD), Ilorin, Kwara State.

This paper examines the practice of biomedical waste management in some medical facilities in Ile-Ife with a view to determining the risks associated with the practice. Four medical facilities with some level of sophistication in waste management were purposively selected for study. The type of waste generated was determined by sorting of waste while handheld scale was used to determine the volume of waste generated. Questionnaire was used to obtain information from the waste management and medical staff of the selected medical facilities. Descriptive (frequencies and percentages) and inferential statistics (Multinomial logistic regression) were used in analysing the data. The study established that the daily per capita waste generation in the medical facilities was 0.51kg. Scrap (Syringes and absorbent paper) (96.7%), infectious (Excreta and dressing swabs) (72.9%) and pathological wastes (Human tissue and body fluid) (57.0%)were the most generated waste while open dumping and pit burial of waste were widely practiced among the medical facilities. Exposure to harmful chemical and radioactive waste (68.8%)and injuries from sharps (52.3%)pose serious health risks not only to the waste managers but health care workers. The paper holds that solutions to the challenges of biomedical waste management practices lie in strict adherence to the global best practices as recommended by the World Health Organisation.Item Seasonal Variation Impacts on Informal Waste Collection in Ibadan, Nigeria(Published by Department of Urban and Regional Planning, Federal University of Technology, Akure., 2023-12-04) Ola, A.B.; Wahab, W.B.; Afonja, A.A.The study explores the impact of seasonal changes on the types and volume of waste handled by informal waste collectors (IWCs) in Ibadan, Nigeria.

The contribution of these (CDAS) to the provision of infrastructural facilities in the rural areas of Ido local government area of Oyo state was examined in this paper. Cross-sectional survey research design was adopted for the study. Structured questionnaire was used to obtain information from five purposively selected (CDAS) leaders. the study revealed that water projects and road rehabilitation were the major infrastructural projects executed by all (100%) and 60% of the (CDAS) respectively. The (CDAS) secured funds through compulsory levies paid by members (100%), financial assistance from members of the communities in diaspora (40%), philanthropists (40%) and voluntary donations by community members (20%). Infrastructural facilities provided by the associations enjoyed adequate patronage from community members (100%). There was positive perception of the existence and relevance of the (CDAS) in their respective communities by the residents. inadequate funds (60%); lack of financial assistance from government (100%); and non-payment of compulsory levies by some members (40%) were the challenges facing the (CDAS). the paper posits that for any rural infrastructural development efforts of the government to be successful and sustainable, involvement of the rural people (target users) through their (CDAS) is desirable.Item Self-Reliance and Community Initiative: Focus on Community Development Associations in Ido Local Government Area, Oyo State.(Published by Faculty of Environmental Sciences, University of Ilorin, Ilorin., 2018-05-17) Ola, A.B.; Adewale, Y.Y.; Bako, A.I.; Issa, B.S.The observed inadequacy in infrastructural facilities in the rural areas of Nigeria has triggered the formation of community development associations (CDAS) to engage in infrastructural development in their respective communities.
