This research addresses the evolution of slums in two specific areas of Lagos City, a consequence of rapid urbanization in developing economies. The study aims to analyze the key characteristics of slums’ evolution while analyzing mathematical spatial changes within the Badia-East and Makoko slum areas in two decades, focusing on promoting sustainable urban growth. The integration of Remote Sensing (RS) technology and Geographic Information System (GIS) tools has dramatically facilitated the monitoring of Land Use Land Cover (LULC) changes over two decades. This research used Landsat imagery acquired in 2000, 2010, and 2020 to meet our research aims. The research applied supervised classification and the Normalized Difference Built-up Index (NDBI) for image mapping and mathematical-based analysis. Research created a spatial framework using grid-cell maps, performed change detection, and generated detailed maps to support our analysis. A comparative analysis was also performed in the.

Ancient city centres are characterised by inadequately planned/unplanned land use and unsecured tenure system, leading overtime to the development of different forms and grades of slum in and around urban core area. This research studied the slum in the urban core of Akure, Nigeria deploying tools of Geographic Information System for comprehensive analysis of slum peculiarity for guiding action. Descriptive and analytical methods based on field survey and extraction of information from satellite images were utilized. The study examined the existing situation in the study area in terms of its housing system, conditions of infrastructure, socioeconomic status of respondents and adequacy of livelihood with respect to slum indicators as defined by UN-Habitat (2003). The study revealed specific areas of higher degree of slum conditions and a representation of level of changes in land uses. Another finding shows high rate of conversion, mainly from residential land uses to other uses as the major characteristic of land use changes in the area. Poverty has constituted a dominant factor for continued existence of slum conditions due to paucity of employment opportunities. The study further discovered diverse manifestations of slums within a locality attributed to factors such as strong family linkages, structure of property ownership and high level of economic dependency. Economic empowerment through aids and supports for Small Medium Enterprises (SMEs), development of market network strategy for Akure and development of a comprehensive land use plan that would ensure sustainable growth of the city core area are canvassed.

Urban renewal has been regarded as a sound approach to promoting land values and improving environmental quality. An urban renewal programs is supposed to address undesirable urban conditions. However, the real problem in this regard is that the determination of the level of substandard situations that can be considered undesirable is usually based on planning standards and varies from place to place and time to time. This study attempts to review the general concept of urban renewal and various approaches. It highlights the existing physical and socio-economic characteristics of the study area. To establish how urban renewal programs can be achieved simultaneously using GIS .The methodology included digital mapping techniques, ground survey to establish the factors responsible for deterioration in the study area, conversion of surveyed data into digital form as attribute of the spatial data (variables considered) and query of each variables to show individual conditions in the study area. The results obtained showed that GIS easily allowed the linking of spatial data with attribute data based on which queries and spatial analysis carried out. The level of deterioration is determined using weighted index analysis method of identifying a slum, thus major rehabilitation is suggested as the best approach for the study area. Finally, a renewal plan is proposed as way of solving the identified problems in the study area.

The twentieth century witnessed a rapid shift in population from rural areas to urban areas in most countries of the world. There is a growing concentration of people in urban centers and Ugep in Yakurr Local Government Area of Cross River State, Nigeria, is a case study. Housing demand increases due to growth in population, rapid urbanization and industrialization. It influences quality living and its shortage more often leads to overcrowding, unsanitary conditions and slum development. The aim of this study is to assess urbanization and slum development in Ugep urban. The specific objectives include; (i) to examine the cause of urbanization and slum development in Ugep Urban. (ii) to determine the negative impact of urbanization and slum in the area under study. (iii) to make recommendations for sustainable growth and development of Ugep urban. Field surveys and questionnaire administration were used for the collection of socioeconomic data. Other methods for data collection include oral interview, direct physical observation and focused group discussion. Purposive sampling techniques was adopted and a total of 200 copies of the semi-structured questionnaire, 50 each were randomly administered in each of the four major political wards in Ugep namely, Bikobiko, Ijiman, Ijom and Ikpakapit which make up Ugep Urban. The data collected were analyzed using simple percentages and tables. The result of this study shows that Ugep urban is highly urbanized considering its increasing population in all the wards. Poverty is prevalent with a high occupancy rate. The study revealed that residents live in substandard houses without basic amenities and services. The study also revealed high incidences of criminal activities and poor health conditions due to unsanitary conditions. The study recommended the creation of employment opportunities and the provision of basic amenities and services to reduce rural-urban migration. It recommended a reduction in the cost of building materials and encouraging long-term loans with low-interest rates. The study also recommended that the Area Planning Authority in Ugep should set and enforce standards for public and private buildings and ensure that development plans obtain a building permits before structures are erected.

Abstract: Urban renewal brings improvement to the physical and housing conditions and makes a city a suitable place for living. The commitment of the Plateau State government to giving a face lift to the aesthetic beauty of the capital city of Jos, through urban renewal, has been reiterated on several occasions. The city witnessed series of crises almost throughout the last decade with the high density residential areas mostly affected. The implementation of the proposed urban renewal programmes in the capital city, therefore, call for caution and concern. This study, having investigated through questionnaires, interview and field observation, the various socio-economic characteristics of three high density residential areas, namely, Ungwan Rogo, Gangare and Dadinkowa, respectively sampled from the Northern, Central and Southern strata of the metropolis, established that the areas are slums. Results of investigations revealed that over 75% of the total landuse is residential and abo.

This study analyzed the spatial assessment of urbanization in Mgbougba, PH Township, Orazi Rumueme, and Eligbam Rumueme using GIS to determine the spatial and temporal changes. This study adopted data from a secondary source, which includes Landsat (7) TM Thematic Mapper of 1999, 2009 and 2019 of the study areas which were further analyzed to determine spatial and temporal changes that have occurred in the study areas. Findings from this study based on the classified Landsat imageries revealed that in Mgbougba, spatial changes were observed as a result of an increase in built area value of 591 in 1999 to 4066 in 2009 and to 6661 in 2019, hence, caused a reduction in vegetation cover with the value of 5038 in 1999 to 3733 in 2009 and to 1515 in 2019 and also a reduction of water body with a value of 363 in 1999 to 276 in 2009, with the absence of water body in 2019. Spatial changes also occurred in PH Township built-up areas indicating an increase in signature values from 3329 in 199.
