    Green infrastructure delivery in southwestern Nigeria.
    (Department of Urban and Regional Planning, Faculty of Environmental Design and Management, Obafemi Awolowo University, Ile-Ife, Nigeria., 2024) Olumuyiwa, Sola Atoyebi.
    This study examined the socioeconomic characteristics of residents in different developmental areas of Abeokuta, Osogbo and Ado Ekiti; the provider, condition and level of utilization of green infrastructure; residents’ perception of green infrastructure delivery. It also determined factors influencing residents’ perception of green infrastructure delivery in the study area. These were with a view to providing information that could enhance environmental management in the study area. Data for the study were from primary and secondary sources. Primary data were collected through physical observation and administration of questionnaire on residents. Using multistage sampling, Abeokuta, Osogbo and Ado-Ekiti were stratified into three developmental zones (core, transition and suburban) followed by identification of residential areas in the zones. In each of the cities, there were selections of residential areas and selections of streets in the selected residential areas across the different developmental zones of the cities. In the selected streets, every 20th building was selected. Thus, 199, 179 and 115 residential buildings were sampled across the developmental zones of Abeokuta, Osogbo and Ado-Ekiti respectively where respondents were selected to arrive at 493 residents that formed the sample size for the study. Data collected were analysed using both descriptive and inferential statistics such as frequency distribution, Chi-square, analysis of variance, correlation and regression analyses. Findings from the study showed that both male (53.5%) and female (46.5%) respondents were sampled. They were mostly adults of 40 years and above, all educated, and 66.1% of them were married. The respondents had varying income across the cities and also across the developmental zones of the cities. This variation also applied to household size and years of living in their residential areas. Further findings (58.3% of the residents) showed that the government was the major provider of green infrastructure in the three cities, the condition of green infrastructure was just fair with Relative Condition Index (RCI) of 2.63, and the RCI varied across the cities. It was also found that residents made use of green infrastructure for different purposes and the level of utilization is low across the cities. Findings further showed that the residents placed high level of importance on green infrastructure with Relative Importance Index (RII) of 3.06 but the level of satisfaction they derived was low with Relative Satisfaction Index (RSI) of 2.93, and with lower RSI attributable to several green infrastructure. The factors found to influence residents’ perception were socioeconomic characteristics (R2 = 0.299) and condition of green infrastructure (R2 = 0.072). This study concluded that residents’ level of satisfaction with green infrastructure was less compared with the level of importance they attached to them, and residents’ perception of green infrastructure was influenced by their socioeconomic characteristics, and condition of green infrastructure, and this implies the need for effective and efficient green infrastructure delivery in the study area.

    A comparative study of the meaning and value of university campus architecture in southwestern Nigeria
    (Department of Architecture, Obafemi Awolowo University, Ile – Ife, Nigeria., 2024) Akinsola, Musiliu Lawal.
    This study examined comparatively the meaning and value of campus architecture of two universities in Southwestern Nigeria. It examined the personal characteristics of users of the University of Ibadan and Obafemi Awolowo University campuses, examined the physical and socio-physical characteristics of the two university campuses. Analysed the meaning and value of the two university campus architecture, and compared the architecture of the two university campuses. These with a view to providing information that could enhance university campus architecture. A mixed method of quantitative and qualitative evaluation with physical observation was used to collect primary data, while secondary data were sourced from relevant departments. The campus architecture of Obafemi Awolowo University and University of Ibadan, with two classes of respondents; university – staff and students, comprising of 42 and 63 staff, with 401 and 366 students from OAU and UI respectively, were selected using purposive sampling method. The measuring instruments comprised of campus users personal characteristics, physical and socio- physical characteristics of the campus architecture, which were used to assess meaning, while open responses of campus users, likes and dislikes, mental imagery, campus users memories and most important things assessed users’ value of campus architecture which aligned with meaning. Data obtained were analysed using descriptive analysis, means, percentile, chi-square, Cronbach’s Alpha factor analysis, Kruskal-Wallis ANOVA, Crosstabulation, content analysis and Fisher Freeman p-values. Obafemi Awolowo University and University of Ibadan campus architecture evoked campus users’ meaning and value, namely, architecture vitality, campus ambience, quality, wellbeing, campus aesthetics and privacy, circulation and recognition, inclusivity and accessibility, crowding, and facility recognition and cosiness. OAU campus users ranked architecture vitality the strongest in meaning (0.851 Cronbach’s Alpha score; 5.44 mean value) while, UI users ranked campus ambience the strongest in meaning (0.888 Cronbach’s Alpha score; 5.0 mean value). The weakest ranked users meaning was campus facility distinction and cosiness (0.472 and 0.110, Cronbach's Alpha score) and mean value (4.32 and 4.20) for OAU and UI respectively. Also, campus users’ personal characteristics resonates in campus architecture meaning and value, OAU and UI users’ knowledge of the campus was significantly different in all the meaning except for campus crowding (OAU, p < 0.804; UI, p value < 0.245) and facility recognition in OAU (p value < 0.743). For OAU and UI users’ age and number of years on campus was significant in architecture vitality, campus ambience, wellbeing, aesthetics and privacy, circulation and recognition. Religion was significantly different in UI architecture vitality (p < 0.029) and OAU campus quality (p < 0.012), gender was significant in OAU’s circulation and recognition (p < 0.017), wellbeing (p< 0.031). The study concluded that Obafemi Awolowo University and University of Ibadan campus users’ meaning and value were distinct, distinguishable and different. Campus users’ meaning and value of Obafemi Awolowo University campus architecture was stronger than those of University of Ibadan campus users.

    Analysis of Landuse Development in KANO Municipality, Nigeria
    (Department of Urban and regional planning, Faculty of Environmental Design, Obafemi Awolowo University, 2023) ALWADOOD, Ali Jasini
    The study examined; the different landuse nuclei in Kano Municipality; the socio economic characteristics of residents in the identified landuse nuclei; analysed the landuse patterns of the study area between 1950 and 2020; determined the factors influencing landuse development; and examined the physical planning implications of landuse development in the study area. These were with a view to providing information for explaining the current spatial morphology and guidelines for effective policy response towards its management. Fieldwork, Focus Group Discussion (FGD), participatory mapping and questionnaire administration were adopted in eliciting information. Information on the pattern of landuse development was obtained from Topographical map for the year 1950. Others are: aerial photograph (1968) and multi-date satellite images for the years 1975, 1990, 2001, 2010 and 2020. Fishnet technique at 500 meters intervals was used in the selection of sample locations. A total of 1,421 points were obtained with 894 located within residential areas, thereby constituting the sample size for questionnaire administration. The obtained information were analysed using descriptive and inferential statistics while the spatial aspect was analysed using Nearest Neighbour Analysis, Overlay operation and Buffering. The study identified 92 independent development nuclei in Kano Municipality with residential landuse representing 63.3%. Most of the development nuclei (89.1%) were characterized by multiple landuse types while 56.7% developed as post-colonial organic development. The study observed a wide disparity in the socio-economic characteristics of the residents in the identified development nuclei with: age, household sizes and length of stay, inversely proportional with increase in distance from the ancient walled city. Similarly, development nuclei were polarised along ethnic, income and educational disparities. The municipality witnessed a growth from 27.5 km² from the year 1950 to 355.3 km² in 2020, which was a growth of 1,192.8% in 70 years (annual growth of 17.3%). Factors such as land affordability, land availability, serenity of the area, and social ties (Family and Friends) were identified as the main factors influencing land use development, with each contributing, 12.0%, 10.6%, 9.9% and 9.2% respectively. The land use development of Kano municipality showed several significant implications for urban planning, such as the development of poor environmental quality in the older organic nuclei within the ancient walled city, the conversion of open spaces to built-up areas foe economic ventures, the loss of historical monuments, and the development of social segregation that collectively hindered interactions and tolerance among residents. The near absence of adequate water and electricity supplies, poor conditions of roads and other social facilities were also identified. In essence, the multifaceted challenges discovered by the landuse development in Kano municipality emphasize the urgency of a holistic and sustainable urban planning approach. It is essential to strike a balance between economic growth and preserving the city's heritage, enhancing environmental quality, promoting social integration, and investing in critical infrastructure. Only through a comprehensive and forward-thinking urban planning strategy can Kano municipality fulfil its potential as a thriving, inclusive, and vibrant urban center for its residents

    Physical Planning Implication of Urban Agricultural Practice in Lagos Metropolis.
    (Department of Urban and Regional Planning, Faculty of Enviromental Design and Management. Obafemi Awolowo University., 2023) OLALEYE, Daniel Oluwasola.
    This examined the spatial distribution of urban agriculture practice in Lagos Metropolis; identified and examined the land tenure system in urban agriculture practice; examined the socio-economic profiles of urban agriculture stakeholders; identified and examined the factors influencing urban agriculture practice; identified and examined the impact of urban agricultural practice on residents; and determined the relationship between urban agriculture and physical planning. This was with a view to provide planning policy that will stimulate the growth of urban agriculture. The primary data were obtained through administration of questionnaire on three (3) sets of respondents. These are: farmers, residents and staff of agencies responsible for the control and development of agriculture and its land use in Lagos metropolis. Reconnaissance survey revealed that there are 9186 registered farmers who are into urban agricultural practice in all the relevant local government areas in Lagos metropolis. This figure was made up of farmers involved in the production of five (5) different types of urban agricultural products. These are: flower (160), vegetable (1367), poultry (1640), fishery (2170), and livestock (3849). These 9186 farmers form the population for this study. A total of 243 (10%) farmers were randomly sampled from the sample frame using the already established and identified clusters for each type of agriculture activities in each of the LG area, however only 227 of the questionnaire were used for the analysis in this study. Residents around the clustered farm sites were stratified into three different strata using the distance of buildings from the farm sites. These are: 0-300 metres, 301-600 metres and 601-900 metres. Physical counting revealed that there are 240 streets with 6228 buildings. The study randomly selected 20% of the streets from each stratum. From the selected streets, 20% of buildings were selected, thus a total of 333 were selected. From a selected building, a household head with the longest stay was sampled. Where a household head is not available, the oldest available resident will be chosen in lieu. This study revealed that in Ojo, between 2013 and 2022, the size of vegetable farms decreased from 173.02ha to 156.65ha. Similarly, the number of horticultural gardens in Eti-Osa local government decreased from 63 in 2008 to 28 in 2022. It was further revealed that the officially designated phase II of Fish Farm Estate with a total land mass of about 30ha has been converted to other forms of agricultural by 2022. From the findings, major constraint to UA is access to land. Overall, 17% (39) of farmers own their farmland, nearly two-third (65%) rented the land they are using, while another 15% are squatters. Chi-square statistic indicted that there is relationship between gender of farmers and the type of urban agriculture activities they practice (χ2 =13.684; p=0.008). Findings showed that more residents living within 0-300m distance from the farms complained about farmers’ activities generally as compared to those living outside this radius. This pattern is the same for all types of farming activities in the neighbourhood except horticulture garden. Majority of residents (225/304) were of the opinion that farming and agricultural are appropriate in cities and urban centres. Generally, the study revealed that the most important positive impact of UA as perceived by all residents is enhancement of environmental protection law (PI = 4.89). Representative of Agricultural Land Holdings Authority (ALHA) indicated that there are areas within the metropolis where agriculture activities are officially permitted. The study concluded that urban agriculture has the potential to contribute to local food security by increasing the availability and access to fresh agriculture produce. In the future, the ability of cities to produce at least a portion of their own food supply will become important as a result of changes in several aspects of urban area and its dwellers.
