1.1 Introduction
Urban planning refers to the process of designing and regulating the use of spaces within cities to create orderly and functional environments that address the needs of residents. It involves land use management, infrastructure development, transportation planning, and environmental sustainability (Akinbami, 2017). Urban planning plays a crucial role in shaping the health and well-being of populations by determining the organization, infrastructure, and services within cities. In Nigeria, the rapid pace of urbanization has led to significant challenges in public health, largely driven by poor planning and management. As cities expand, issues such as overcrowding, inadequate housing, poor sanitation, and limited access to healthcare services have become increasingly prevalent. These factors are closely linked to a rise in public health issues, including infectious diseases, respiratory conditions, and other health problems exacerbated by environmental factors (Adelakun, 2019).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Research hypothesis and questions, Limitation of the study and Definition of terms.
1.2 Background of Study
The history of urban planning in Nigeria and its impact on public health is rooted in the colonial era when British administrators introduced formal city planning practices. These early efforts focused on segregating European settlers from indigenous populations and establishing basic infrastructure in key cities like Lagos, Ibadan, and Port Harcourt (Mabogunje, 2017). The planning approach primarily addressed the needs of colonial officials, with minimal attention to the health and well-being of the local population. Consequently, large segments of urban residents were confined to poorly planned areas with inadequate access to clean water, sanitation, and healthcare services, leading to frequent outbreaks of infectious diseases.
Recent decades have seen increased awareness of the need for integrating public health into urban planning in Nigeria. Various initiatives have been launched to address issues such as housing, sanitation, and pollution. However, challenges remain, including poor coordination between government agencies, corruption, and inadequate funding. The rise of non-communicable diseases, driven by urban lifestyles, has also underscored the need for better urban planning to create healthier living environments (Akinola & Adeyemi, 2020). Despite these efforts, the impact of urban planning on public health in Nigeria remains a critical concern, with significant disparities in health outcomes across different urban areas.
The rapid urbanization in Nigeria has led to significant challenges in both urban planning and public health. With more than half of the country’s population now residing in urban areas, cities have grown faster than the development of adequate infrastructure and services. This has resulted in overcrowding, poor housing conditions, inadequate sanitation, and insufficient healthcare services, all of which directly impact public health (Adedayo & Oni, 2019). The nexus between urban planning and public health is critical, as poorly planned urban environments can contribute to the spread of diseases, environmental degradation, and a decline in the overall quality of life for urban dwellers.
Historically, urban planning in Nigeria has often neglected the importance of public health. The focus has largely been on accommodating rapid population growth and expanding urban spaces, with little attention paid to the health implications of such developments. The consequence is a proliferation of slums, poor waste management systems, and a lack of green spaces, which together create environments that are conducive to the spread of infectious diseases such as malaria and cholera (Akinwale & Abiodun, 2020). Additionally, poor air quality, resulting from inadequate traffic management and industrial emissions, has led to an increase in respiratory conditions among urban residents (Ogunleye et al., 2021).
Effective urban planning should address key determinants of health, such as housing quality, access to clean water, sanitation, and opportunities for physical activity. However, the disconnect between urban planning and public health objectives in Nigeria has been a major barrier to achieving these outcomes. The situation is further complicated by weak enforcement of urban planning regulations, inadequate funding, and a lack of political will to implement sustainable planning practices (Ibrahim & Ojo, 2018). As a result, public health issues continue to escalate in Nigerian cities, disproportionately affecting low-income and marginalized communities who are often confined to the most poorly planned areas.
Urban planning has the potential to improve public health by creating environments that promote healthy living. Well-planned cities prioritize accessible healthcare, adequate housing, efficient waste management systems, and the availability of green spaces, all of which contribute to better health outcomes (Oluwaseun & Idowu, 2021). However, in Nigeria, the lack of integration between urban planning and public health objectives has resulted in cities that struggle with poor air quality, unsafe water supplies, and increased vulnerability to diseases (Akinbami et al., 2020).
The impact of ineffective urban planning is evident in the high rates of diseases such as malaria, cholera, and respiratory infections in Nigeria’s urban areas. The concentration of people in poorly planned neighborhoods with inadequate sanitation facilities creates breeding grounds for disease vectors, while limited access to clean water exacerbates waterborne illnesses (Nwafor & Igwe, 2018). Additionally, insufficient green spaces and pedestrian infrastructure in many Nigerian cities discourage physical activity and contribute to the growing burden of non-communicable diseases (Ezeh, 2017).
Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the Impact of Urban Planning on Public Health in Nigeria.
1.3 Statement of Problems
Investigation revealed that the relationship between urban planning and public health in Nigeria is marked by significant challenges, primarily due to rapid urbanization, inadequate infrastructure, and poor planning. Despite the growth of cities, urban planning practices have largely failed to accommodate the increasing population, leading to overcrowded and poorly serviced communities. Many urban areas in Nigeria face a lack of proper waste disposal systems, inadequate water supply, and insufficient healthcare facilities, all of which contribute to a high prevalence of infectious diseases like malaria, cholera, and typhoid (Olujimi, 2009). Additionally, poor traffic management and industrial pollution have exacerbated air quality issues, leading to a rise in respiratory diseases (Akinwale & Abiodun, 2020).
The ineffective integration of health considerations into urban planning has resulted in environments that are not conducive to healthy living. Many residential areas lack access to green spaces and safe pedestrian pathways, discouraging physical activity and contributing to the rise in non-communicable diseases such as hypertension and diabetes (Ezeh, 2017). Furthermore, informal settlements, which house a significant portion of the urban population, are often neglected in urban planning efforts, leading to severe health disparities between different socio-economic groups (Adedeji et al., 2018).
Another critical problem is the weak enforcement of existing urban planning regulations, which has allowed for unregulated construction and land use. This has led to the emergence of slums and poorly planned neighborhoods that are vulnerable to environmental hazards, including flooding and pollution, further compromising public health (Ibrahim & Ojo, 2018). Despite some government initiatives aimed at addressing these issues, the lack of coordination between urban planning authorities and public health agencies remains a significant barrier to developing healthy urban environments. It is against the backdrop that this study seeks to address these problems by examining the impact of urban planning on public health in Nigeria.
