Item The activities of informal waste collectors in municipal solid waste management in Ibadan, Nigeria(Faculty of Environmental Design and Management, Obafemi Awolowo University, Ile-Ife, 2016) Wahab, Bolanle; Ola, A. B.Item Appraisal of Vision 20:2020 infrastructure development strategies in Nigeria(Department of Urban and Regional Planning, University of Uyo, Akwa Ibom State, Nigeria, 2020) Ola, A. B.Item Assessment of solid waste management in selected markets in Ilorin, Nigeria(Department of Urban and Regional Planning, Ladoke Akintola University of Technology, Ogbomoso, 2020) Ola, A. B.; Raheem, W. A.; Raheem, W. M.; Ibrahim, RidwanAchieving healthy urban environment in Nigeria entails effective management of market wastes. This study was undertaken to examine effectiveness of solid waste management in market places in Ilorin, Kwara State. A total of five markets spread among the three Local Government Areas of the city were selected for study. A structured questionnaire, containing information on the nature of wastes generated in the markets, means of storing waste, frequency of waste disposal, perceived efficiency of the Kwara State Waste Management Authority among others was used to obtain information from 194 market traders systematically selected from the five markets. Descriptive statistics (frequency and percentages) and inferential statistics (Pearson correlation) were used in analyzing the data obtained. The study revealed that paper (34.7%) and vegetable (29.8%) constituted the dominant wastes in the markets, plastic basket (45.3%) and paper cartons (30%) were the dominant waste storage containers used by the traders, majority (75.4%) of the traders emptied their wastes into the public stationary containers provided in the markets, Kwara State Waste Management Authority was solely responsible for waste collection in the markets and collection was carried out every couple of days (53.1%) mostly in the evening (49.8%). The performance of the Authority was found to be relatively satisfactory (54.3%). It was established through Pearson correlation analysis that there was significant relationship between traders’ income status and the choice of waste receptacle.The wastes evacuated from the markets are carelessly disposed in the only dumpsite maintained by the Authority. Adopting a more hygienic and environmental-friendly waste disposal facilities such as sanitary landfills is recommended.Item A Comparative Analysis of the Operational Characteristics of Informal Waste Collectors: The Case of Ibadan and Abuja, Nigeria(UNIOSUN Journal of Engineering and Environmental Sciences, 2022) Ola, A. B.; Suleiman, R. A.Informal waste collectors (IWCs) have been visible actors in the municipal waste management sector of many cities in Nigeria. Various studies have made attempts to study the operational characteristics of IWCs, however, less emphasis has been made to examine the variations in their operational characteristics across cities in Nigeria. This paper attempts to fill this gap using Ibadan (Oyo State) and Abuja (FCT) as examples. The choice of the two cities was informed by the variation in their access to waste management resources. While Abuja is a federal governmentcontrolled municipality with more resources, Ibadan is a state-controlled municipality with fewer resources. A structured questionnaire was randomly administered to 418 IWCs in both cities. Descriptive and inferential statistics were used in the analysis of the data collected. Abuja IWCs evacuated more waste daily (312 kg) than Ibadan (255 kg). All the sampled Abuja IWCs (100%) used push carts to evacuate wastes while 78.5% of Ibadan IWCs used push carts; Abuja IWCs earned more income (N7,500 daily) compared to Ibadan (N3,000 daily). There was preponderant use of public stationary containers for waste disposal by Abuja IWCs than Ibadan. Few Ibadan IWCs used personal protective equipment (PPE) compared to Abuja. Regression analysis showed that the volume of waste collected by IWCs is influenced by the waste collection fees, method of waste transportation and distance between the collection points and disposal sites. It is therefore recommended that adequate provision of public stationary containers will encourage better waste disposal among the IWCs.Item Development Drivers of Informal Waste Collection in Ibadan, Nigeria(Department of Geography and Environmental Management, University of Port Harcourt, Nigeria, 2020) Ola, A. B.; Raheem, W. A.; Jimoh, M. Y.; Suleiman, A. R.; Raheem, W. M.This paper examined the factors influencing the emergence and expansion of informal waste collection in waste management sector of Ibadan, Oyo State capital. Snowball sampling technique was used to identify and sample 253 informal waste collectors across the five municipal local government areas in the city. A pretested structure questionnaire was used to obtained information from the sampled informal waste collectors. Data collected were analysed using Relative Importance Index (RII), 8 x 8 correlation matrix and factor analysis. Eight major factors were identified as influencing the emergence and expansion of informal waste collection. RII showed that in ranked order of importance, they are: poverty; unavailability of better job; profitability; demand for waste management services; low start-up capital; ease of entry; pressure from parents and guardians and low-skill requirement. The correlation matrix indicated that all the factors correlated positively with one another. The Kaiser-Meyer-Olkin Measure of Sample Adequacy (KMO) value of 0.573 and Bartlett’s Test of Sphericity of p≤ 0.001 established the adequacy of the variables loaded for the analysis. It is concluded that policies and programmes that will enhance integration of IWCs to municipal waste management scheme of the city and check child labour in the sector will go a long way in making the sector more effective in municipal waste management.Item Development Drivers of Informal Waste Collection in Ibadan, Nigeria(Department of Geography and Environmental Management, University of Port Harcourt, Nigeria, 2020) Ola, A.

Yusuf; 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, Nigeria(LAUTECH Journal of Civil and Environmental Studies, 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 state.Item 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, 2021) Suleiman, A.

O.Item Spatial Distribution and Perceived Environmental Health Impacts of Petrol Filling Stations in Ede, Osun State, Nigeria(Faculty of Environmental Sciences, Kaduna State University, Kaduna State, 2020) Olanrewaju, S. O.; Raheem, W. A.; Ola, A. B.; Ige, V. A.The environmental health risks associated with petrol filling stations (PFSs) requires maximum compliance with planning standards in siting them. However, people’s awareness of the effects of PFSs on health and environment is germane to achieving efficient urban environmental health. This study, therefore, examined the spatial distribution of PFSs and the people’s perception of the health and environmental implications of PFSs in Ede, a traditional city in Nigeria. Cross sectional survey design and simple random sampling technique were used for data collection. A structured questionnaire was used in collecting information from the residents. GPS was used in obtaining the coordinates of the PFSs while speedometer was used in determining the distance of the PFSs to each other and residential land use. Fifteen PFSs were identified and sampled in the entire township. The information was obtained from the managers of the PFSs through questionnaire. Also, a total of 150 pretested structured questionnaires were administered to randomly selected residents of adjoining neighbourhoods to the PFSs. Descriptive statistics (frequency and percentages) was used to obtain the residents’ perception of the effects of PFSs on the environment and human health. ARCGIS 10.2 and Nearest Neighbour Analysis were used to establish the spatial distribution of PFSs. The people’s perception of the PFSs effects was low. With the nearest neighbour index of 0.71, the PFSs were linearly clustered along the major roads that dissect the town. There was less compliance to planning standards by majority of the PFSs. Embarking on awareness programme among the residents and enforcement of planning standards in sitting PFSs and other land uses will go a long way in addressing the problems of low perception and non compliance with planning standards.
