    Assessing the sustainable urban development-urban liveability-inclusive physical development nexus in selected cities in north-central Nigeria.
    (2022) Blamah, Nunyi Vachaku.; Magidimisha, Hangwelani Hope.
    The continuous increase in the urban population worldwide has exacerbated the intensity of urban land use conversion and spatial consumption. This motivation for a better urban space led to the evolution of sustainable urban development, urban liveability, environmental awareness, inclusivity, and urban governance. Therefore, this research aimed to establish the intricate links between sustainable urban development, urban liveability, and inclusive physical development in selected cities in North-Central Nigeria. The theories examined were Citizen Participation, Dependency, Modernisation, and Infrastructure. The selected cities were Lokoja, Lafia, and Minna, all incidentally equidistant to Abuja, the Federal Capital City of Nigeria. This research employed a mixed-methods approach by collecting both qualitative and quantitative data. These data sets ranged from satellite imageries used for the spatio-temporal analysis and urban growth simulation through ArcGIS, Q-GIS, and the Artificial Neural Network. The extent of infrastructure provision and their methods were appraised using the instrumentality of the nearest neighbour analysis and the partial least square analysis using the SmartPLS. The research also appraised the stakeholders’ perceptions and methods of infrastructure provision through a word cloud analysis using NVivo analytics. In analysing the provision and condition of the infrastructure in North-Central Nigeria, educational infrastructure was found to be inadequate and poorly maintained; inadequate budgetary allocations exacerbated the problem of urban infrastructure overuse; illegal developments often overtook sites reserved for infrastructure; and funding, vandalism, and project continuity were cited as critical factors. The infrastructure that suffered the highest maintenance neglect was the urban water supply, education infrastructure, and the health care facilities. Political motivation and the population played the most significant roles in the region's urban infrastructure or project development. The triad of consumption, access, and equity was used to evaluate Hangwurian City Development's (HCD) proposed sustainable urban infrastructure development plan. Convergent validity was strong in the region, where the AVE was significant at 0.56 or more. A compact development model was found to be a valuable indicator for qualifying the cities. It was found that the challenge of planning regulation and siting of infrastructure could be addressed effectively, however, the public and private sector promoters of projects had to stick to their parts of the bargain. Cities across North-Central Nigeria had to undertake citizen-focused infrastructure planning and development. Therefore, the researcher concluded that city development and urban growth could be moderated through the instrumentality of adequate infrastructure provision and planning to prioritise the needs and desires of residents. This is achievable by adopting the Hangwurian City Development Model, which helps to promote cities without ills.

    Planning and Social Housing in the context of spatial justice and right to the city in Alexandra Township, South Africa: 2001 TO 2016.
    (2022) Mndze, Siphumeze.; Mchunu, Koyi Humphrey.; Myeni, Sithembiso Lindelihle.
    This study aims to investigate the manner in which social housing contributes to spatial justice and the right to the city. It shows that social housing does not create spatial justice and the right to the city, although it contributes to them. The study applies concepts such as spatial justice, social justice, integration and participation. The theories that are applied constitute critical theory, Rawls’ theory of justice, new urbanism and smart growth theory. The concepts and theories help in guiding the argument in terms of investigating the manner in which social housing contributes to spatial justice and the right to the city. A mixed-method approach was used as the research methodology and design. Semi-structured interviews and questionnaire surveys were conducted with social housing beneficiaries in Alexandra Township, which is in the City of Johannesburg in South Africa and was used as a case study. The research findings demonstrate that in Alexandra Township there has been a noticeable but limited contribution of social housing to spatial justice and the right to the city. Through construction of social housing apartments, people had access to shelter and services such as water, electricity, and sewerage, but many still do not have access to sustainable job opportunities. Additionally, there is no consistent access to services such as sewerage, water, and electricity, with frequent outages and blockages in water pipes and sewerage. The rate of crime is high, and people do not enjoy access to amenities and facilities because of fear of being attacked by criminals. The thesis recommends that for social housing to contribute to spatial justice and the right to the city, consultation and participation with the beneficiaries must be undertaken; there needs to be alignment of policy and legislation to facilitate the contribution of social housing to spatial justice and the right to the city; spatial inequality in the cities must be dealt with; and urban safety and security must be improved. This study contributes to academic discourse by providing perspectives about social housing in terms of spatial justice and the right to the city. The research provides notions about re-conceptualisation of social housing policy and legislation in terms of the ideas of spatial justice and the right to the city. Additionally, the study provides notions and a platform for the scrutinisation and discussion of social housing within the context of spatial justice and the right to the city. Finally, this study presents a framework for social housing in relation to spatial justice and the right to city. The framework outlines organised thinking and orientation about social housing regarding its contribution to spatial justice and the right to the city. This thesis argues that future research needs to adopt a broader contextual approach to investigate and understand the urban planning processes leading to limitations of social housing in contributing to spatial justice and the right to the city for beneficiaries. Such future research should utilise procedural planning theory because it deals with making and implementing plans. Additionally, a comparative study which may assist in investigating, analysing, and evaluating social housing in different cities must be undertaken to detect similarities and differences. This must occur to compare social housing in terms of contributing to spatial justice and the right to the city in various cities. This may assist to broaden the thinking and understanding of the way social housing contributes to spatial justice and the right to the city.
