TOPIC: THE CHALLENGES OF URBAN HOUSING DEVELOPMENT AND SUSTAINABLE CITY PLANNING: A CASE STUDY OF AJAH, LAGOS STATE

1.1 Background to the Study

Urban housing development is an important component of urban growth, economic development and social stability. Housing provides shelter and security for individuals and families while also contributing to the physical, social and economic organisation of cities. As urban populations increase, the demand for residential accommodation, infrastructure and essential public services also rises, placing considerable pressure on available land and existing urban facilities. Effective housing development therefore requires proper planning, adequate infrastructure, appropriate land-use allocation and environmental consideration to ensure that residential communities develop in an organised and sustainable manner. The United Nations Human Settlements Programme (UN-Habitat, 2020) emphasises that adequate housing is fundamental to sustainable urban development and that cities must adopt inclusive approaches to address housing shortages and improve living conditions. Similarly, the United Nations (2015), through Sustainable Development Goal 11, identifies the need to make cities and human settlements inclusive, safe, resilient and sustainable. This demonstrates that urban housing development must go beyond the construction of residential buildings to include the provision of essential facilities, environmental protection and effective urban planning.

Sustainable city planning refers to the systematic organisation and management of urban spaces to achieve balanced economic, social and environmental development. It involves the appropriate distribution of residential, commercial and industrial activities, efficient land-use management, adequate transportation networks, environmental conservation and the provision of essential infrastructure. Sustainable planning seeks to ensure that present urban development activities do not undermine the ability of future generations to enjoy a healthy and functional urban environment. According to Campbell (1996), sustainable development in urban planning involves balancing competing interests associated with economic growth, environmental protection and social equity. Similarly, Wheeler (2004) explains that sustainable urban development requires coordinated planning approaches that promote compact urban growth, efficient transportation, environmental responsibility and improved quality of life. Consequently, sustainable city planning is essential for managing the challenges associated with rapid urbanisation, particularly in developing countries where population growth often occurs faster than the provision of housing and infrastructure.

The rapid expansion of urban populations has made housing development a major challenge in many developing countries, including Nigeria. Urbanisation has increased the demand for residential accommodation, particularly in major commercial centres where employment opportunities, educational institutions and economic activities attract large numbers of people. However, housing supply in many urban areas has not always expanded at the same rate as population growth, resulting in housing shortages, overcrowding, informal settlements and increasing pressure on available infrastructure. The World Bank (2016), in its assessment of Nigerian urbanisation, highlights the importance of effective urban management, infrastructure provision and institutional coordination in addressing the challenges associated with rapid urban growth. Likewise, UN-Habitat (2020) identifies inadequate housing, urban poverty and insufficient basic services as significant challenges affecting sustainable urban development. These conditions demonstrate that urban housing challenges cannot be addressed through building construction alone; they require integrated city planning, effective land administration and coordinated infrastructure development.

In Nigeria, urban housing development is affected by several interconnected problems, including high land acquisition costs, inadequate housing finance, poor infrastructure, population pressure, planning deficiencies and the increasing cost of building materials. These challenges make it difficult for many households to obtain affordable and decent residential accommodation, particularly in major urban centres. Furthermore, inadequate coordination between housing development and infrastructure provision often results in residential areas emerging without sufficient roads, drainage systems, electricity, water supply and waste management facilities. The Federal Republic of Nigeria (2012), through the National Housing Policy, recognises the need to improve access to adequate and affordable housing through appropriate institutional arrangements, housing finance and effective development strategies. Similarly, the National Urban Development Policy (Federal Ministry of Lands, Housing and Urban Development, 2012) emphasises the importance of coordinated urban development, effective land-use management and infrastructure provision. These policy concerns demonstrate the need for sustainable approaches to housing development that address not only the availability of residential buildings but also the quality and functionality of the surrounding urban environment.

Furthermore, ineffective land-use planning and weak enforcement of physical development regulations constitute major obstacles to sustainable housing development in Nigerian cities. Urban land is a limited resource that requires proper allocation to accommodate residential buildings, commercial activities, public facilities, transportation infrastructure and environmental protection. When development takes place without adequate planning control, residential settlements may emerge in environmentally unsuitable locations, roads may become inadequate, drainage systems may be obstructed and public open spaces may be lost to unregulated construction. Such conditions can increase the risk of flooding, environmental degradation and poor living standards. Watson (2009) argues that urban planning in developing countries faces significant institutional and political challenges, particularly where formal planning systems struggle to respond to rapid urban growth and the realities of informal development. Similarly, UN-Habitat (2015) emphasises that effective urban planning and design are necessary for creating compact, connected, inclusive and sustainable cities. Therefore, the effectiveness of land-use regulation and development control is important in determining whether urban housing growth contributes to organised and sustainable city development.

In Lagos State, urban housing development has become increasingly important because of rapid population growth, economic concentration, rural-urban migration and the expansion of residential and commercial activities. Lagos is one of Nigeria’s most important economic centres and experiences considerable demand for residential accommodation from workers, business owners, students and other urban residents. However, the rapid growth of the metropolitan area has created pressure on land resources, transportation infrastructure, drainage systems, public utilities and environmental management. Residential expansion into peripheral communities has also increased the need for coordinated planning to ensure that new developments are supported by adequate infrastructure and public services. The Lagos State Government (2013), through its Lagos State Development Plan 2012–2025, recognises housing, transportation, infrastructure and environmental management as important priorities for sustainable development. Furthermore, Gandy (2006) examines the infrastructure crisis confronting metropolitan Lagos and highlights the challenges associated with rapid urban expansion and inadequate infrastructure provision. These conditions make sustainable housing development and effective urban planning particularly important for ensuring that Lagos continues to grow in an organised and environmentally responsible manner.

Ajah, in Lagos State, provides an important setting for examining the challenges of urban housing development and sustainable city planning because of its growing residential population, expanding property developments and increasing demand for urban infrastructure. The area has experienced considerable residential and commercial expansion, attracting households, property investors and businesses seeking accommodation and economic opportunities within the Lagos metropolitan region. Its development is associated with the wider expansion of the Lekki-Ajah corridor, where increasing residential construction has created greater demand for roads, drainage, electricity, water supply, waste disposal and other essential services. However, the sustainability of this expansion depends on the extent to which housing development is supported by adequate infrastructure, effective land-use planning, environmental management and development control. UN-Habitat (2015) emphasises that sustainable urban development requires the integration of land-use planning, infrastructure, transportation and environmental considerations. Similarly, Watson (2009) highlights the importance of institutional capacity and appropriate planning approaches in managing urban growth in developing countries. Against this background, this study examines the challenges of urban housing development and sustainable city planning in Ajah, Lagos State, with particular attention to housing affordability, infrastructure provision, land-use planning and environmental sustainability.

1.2 Statement of the Problem

Urban housing development and sustainable city planning remain major challenges in rapidly growing urban areas, particularly in developing countries such as Nigeria. The increasing demand for residential accommodation has encouraged the expansion of housing developments into different parts of Lagos State, including peripheral communities such as Ajah. However, the rate of residential expansion has not always been matched by adequate infrastructure, effective land-use planning and the provision of essential public services. Consequently, some developing residential areas experience inadequate road networks, poor drainage systems, insufficient water supply, ineffective waste disposal and limited public facilities. These conditions may undermine the quality of residential environments and reduce the sustainability of urban development. Ilesanmi (2012) identifies inadequate infrastructure investment, inappropriate implementation of housing policies, high land costs and weaknesses in urban governance as important challenges affecting sustainable housing development in Lagos. Similarly, UN-Habitat (2020) emphasises that sustainable housing requires coordinated provision of infrastructure, essential services and appropriate urban planning. This situation raises concerns about whether housing development in Ajah is progressing in a manner that supports sustainable urban growth.

Another problem relates to the increasing difficulty of ensuring affordable and decent housing for different categories of residents. Although the expansion of residential developments in Ajah has created additional housing opportunities, the cost of land, building materials, construction and housing finance may limit the ability of low- and middle-income households to obtain suitable accommodation. Furthermore, some residential developments may prioritise investment returns and exclusive housing arrangements without adequately addressing the wider housing needs of the surrounding population. Adebayo and Ojolowo (2022), in their study of population dynamics and housing characteristics in Ajah, found that housing development in the area is associated with population sprawl, informal development, varying housing quality and inadequate infrastructure. Their findings also identified land affordability, proximity to urban centres and housing preferences as important factors influencing residential development. This indicates that increasing housing construction does not necessarily guarantee equitable access to adequate housing. Therefore, there is a need to examine the affordability and accessibility challenges associated with urban housing development in Ajah and how these challenges affect sustainable city planning.

Furthermore, uncontrolled physical development, inadequate development control and environmental degradation constitute serious challenges to sustainable urban planning in Lagos State. Residential construction in environmentally sensitive locations, particularly flood-prone areas, may increase exposure to flooding, property damage and other environmental hazards. Inadequate drainage infrastructure, indiscriminate waste disposal and the loss of natural vegetation can further worsen environmental conditions in expanding residential communities. Wahab and Ojolowo (2018), in their study of urban development in flood-prone areas of metropolitan Lagos, found that ineffective development control and inadequate compliance with planning and building regulations contributed to development in floodplains. Similarly, Adelekan (2010) identifies uncontrolled urban expansion, inadequate infrastructure and poor drainage management as important factors increasing the vulnerability of coastal communities in Lagos to flooding. These findings highlight the need to investigate the extent to which planning regulations, environmental protection and development control are effectively implemented in Ajah to ensure sustainable housing development.

Finally, the coordination of housing development, infrastructure provision and urban planning remains an important concern in Ajah. Sustainable city planning requires effective cooperation among government agencies, private developers, planning authorities, infrastructure providers and local communities. However, weak institutional coordination, inadequate enforcement of planning regulations, insufficient infrastructure investment and limited community participation may undermine the achievement of sustainable urban development. Soyinka, Siu, Lawanson and Adeniji (2017) identify urban sprawl, informal development and infrastructure inadequacy as significant challenges affecting sustainable urban development in Lagos metropolis. Similarly, Lawanson, Oyalowo and Nubi (2021) identify weak institutional capacity, inadequate data and poor governance strategies as obstacles to implementing sustainable development objectives in Lagos. Although these studies provide important insights into urban development challenges in Lagos, the specific combination of housing affordability, infrastructure provision, land-use planning and environmental sustainability in Ajah requires further investigation. It is against this background that this study seeks to examine the challenges of urban housing development and sustainable city planning in Ajah, Lagos State.
