There is a general paucity of explanations for the emerging social and spatial changes in the pattern and socio-economic traits of urban residential housing units in Nigeria. Hence, this study examined the spatial pattern of residential neighbourhoods; assessed the quality of residential housing units; and evaluated the correlation between the socio-economic position of respondents and housing quality in Akure, Nigeria. Data were derived from the household questionnaire, remotely sensed data (Landsat 8 OLI/TIR, 2021), a Google Earth map, a Street Map of Akure Township, and personal observations. The study adopted a step-wise sampling technique to select 383 samples from 139,069 heads of households in Akure in 2021. Data were analysed using percentage distribution, Pearson Correlation Coefficient, and t-test. Results indicated varying housing qualities across three residential zones in Akure, Nigeria; houses in the low-density residential areas were of better quality than the other residential zones. The quality of houses occupied was influenced by the type of occupation, level of education and average annual income of residents. The study concluded that inadequate housing facilities are fundamental to the observed deteriorating housing qualities in the study area. Therefore, the study suggested improvement of the existing infrastructures and the provision of new ones in the study area. The main contribution of this study is to proffer solutions for a sustainable housing delivery system to facilitate a better quality of life in Nigerian urban centres.

The study assessed the spatial and temporal patterns of urban expansion; and identified the major drivers of urban expansion in the study area. The study utilised data collected through the use of inventory data sheets and handheld Global Positioning System (GPS) for ground truthing. Also, data were obtained from topographical map and satellite imageries. Data were analysed using Remote Sensing and Geographical Information System (RS/GIS) tools and Analysis of Variance (ANOVA). Results showed that Ede has greatly grown and developed since 1966 at an annual growth rate of %. Moreover, results indicated that the growth patterns identified in the study area did not conform to any of the single known theories of urban growth but, rather a combination of both concentric and sectorial patterns. Furthermore, the study found that improved socioeconomic activities, expansion of the residential areas, and establishment of higher educational institutions were the major drivers of growth in Ede. While the study appraises the practicality of growth centre strategy to urban development, it harangued the unrestricted nature of urban expansion in the study area. Nevertheless, the study underscores the relevance of top-down approach to the growth and development of the study area. The study recommended the implementation of planning controls to aid well-defined land uses in the study area.

Therefore, it becomes highly necessary to determine suitable sites for landfill. Using remote sensing and geographic information tools and technologies the study identified the scenes of present dump sites; evaluated the conditions for selecting landfill sites; and determined suitable landfills in Ajaokuta, Nigeria. Data for the study were sourced from Sentinel-2A, 2021. Integrated GIS-based analysis using multi-criteria evaluation method was employed to scrutinise the appropriateness of the existing dumpsites for siting landfills. However, with reference to Federal Environmental Protection Agency (FEPA) guidelines, results of buffering and proximity analyses indicated that none of the existing dumpsites could be converted to landfill sites. Moreover, a fuzzy overlay of all the criteria considered was employed to i...

The study adopted both statistical and descriptive approaches to achieve the formulated objectives. Rainfall and temperature data were obtained from the Ghana Meteorological Agency, Navrongo-Ghana, and the World Bank Climate Change Knowledge Portal. The main instruments used to gather information from the respondents were questionnaire, structured interview guide and field observation. Data were analysed using SPSS version 20 and presented in tables and figures. The study revealed that there were yearly irregularities in the amount and intensity of rainfall with increasing number of dry spells, implying the area is currently contending more with climate variability. It also revealed that climate variability has had negative implications on food crop production in the district such as unpredictability of onset of rains, crop failure and low yield. The cu...

Thus, this study analyzed the spatiotemporal land use/land cover changes of Ijebu Ode, Nigeria between 1986 and 2021. This is with a view to assessing the pattern of landscape fragmentation in the study area. The study used data obtained through Global Positioning System (GPS) receiver and satellite imageries (Landsat 5 MSS/TM, 1986; Landsat 7 ETM+, 2000 and 2014; and Landsat 8 OLI/TIR, 2021). Data were analyzed using spatial landscape metrics. Results indicated that Ijebu Ode has witnessed dramatic increase of built-up areas between 1986 and 2000 by 11.03%, 2000 to 2014 (65.24%), and 2014 to 2021 by 131.25%. Expansion of the built-up area was aided by reductions in bare land (1986 to 2000, 15.78%; 2014 to 2021, 98.27%), and the cultivated area by 47.74% between 1986 and 2014. Landscape metrics were estimated over the four epochs of study. Results revealed that most...

Data for the study were obtained from administrative maps of the study area, population data and satellite imageries. All of these were complemented with ground validations using Global Positioning System (GPS) receiver. Periods of change analysis were divided into two epochs; 1986 to 2002 and 2002 to 2017. The imageries were classified into four landuse/cover classes based on Anderson’s modified version of supervised classification scheme. Accuracy assessment of the imageries was carried out using 100 randomly sampled ground truth points. Ten spatial metrics were selected for analysis using Fragstats program. Results show a significant loss in vegetation due to conversion (Land Consumption Rate, LCR = 0.025, 0.019 and 0.027; Land Absorption Coefficient, LAC = 0.012 and 0.048). Moreo...

This paper identified the typology and distribution patterns of urban and rural settlements in Ijesaland, Osun State, Nigeria. Ijesaland was found to be a diverse region, it contained a large number of most remote rural communities, large densely populated urban centers, and a wide range of areas in between. Designation of Ijesa settlements into rural and urban communities was attempted through population size and functions. The function criterion was considered from the perspectives of political status, primary activities, industrial establishments, and commercial function of all the settlements in the study area. A juxtaposition of size and function criteria revealed that there were thirty-five urban centres consisting of one city, four large towns, eleven intermediate-sized towns and nineteen small towns in Ijesaland.

The paper noted that in order for the urban infrastructural services to keep pace with the growing population, there is the need for governments at the various levels and private organizations to increase their capacities to provide and manage urban infrastructural services. The study recommended that private involvement in infrastructure provision and maintenance could yield significant savings on social cost and improve urban infrastructural services. Data for the study were sourced from the existing data published by both public and private. Fourteen out of the thirty-six states in Nigeria and the Federal Capital Territory were selected for analysis. The 14 states were randomly selected from the six geo-political zones of the country. All data extracted were calculated based on the percentages of urba...

The study aimed at assessing the contribution of communal efforts to regional development with a view to providing a method to aid rural and shanty towns’ development. Results showed that regional development is a task of both the community and government (at various tiers). In addition, it was found that projects executed by the community often receive proper maintenance compared to that of the government. Also, it was discovered that while capital accumulation was the major problem facing the community, government on the other hand is often faced with poor maintenance of the community projects. For community development projects to serve and achieve their purpose of regional development, it was recommended that public-private participation should be encouraged; soft loans should be made available to Community Based Organisations for the execution of community developmen...

The study considered several potential determinants of residence location choice including occupation, socio-economic status as well as quality of the housing unit and its neighbourhood. It also examined the effects of accessibility to different activity locations on residential choice decisions. Data were obtained through a set of household questionnaire administered through stratified sampling technique. While the importance of each of the locational factors was tested using the mean, the level of significance was ascertained through the t-test. The results showed that all factors considered were significant, though at varying degrees. Socio-economic status such as income and education of the households were identified as the most significant factors of residential location decision in south-western Nigeria. The study conclu...

The study identified the service centres; found out and examined the range of the spatial influence of the service centres; and examined the factors responsible for the observed movement pattern(s) in the study area. Twenty-seven ‘Central Place Functions’ were identified which were used to determine the sample size and also to organise the area into hierarchical order of service centres. Results revealed that, based on communality values, there were three classes of services in the study area. These are: Class I with values greater than 1; Class II values between 0.1 and 0.99; and those with communality values of less than 0.1 were were regarded as Class III. In addition, there were six hierarchies of service centres in the study area: the main centre, sub-centres, higher-order centres, lower-order centres, rural - urban fringe and the remote rural ar...
