LITERATURE REVIEW

Conceptual Review

Informal Settlements:

Informal settlements, also known as slums or shantytowns, are areas characterized by haphazard and unauthorized housing development, typically lacking formal land tenure and basic infrastructure (UN-Habitat, 2016). These settlements often emerge as a result of rapid urbanization, rural-to-urban migration, and inadequate urban planning (Roy, 2005). In Gwagwalada Town and similar urban centres in developing countries, informal settlements represent a significant proportion of the urban landscape, reflecting the challenges of accommodating a growing population within limited urban space (Angel et al., 2011).

Several factors contribute to the formation and proliferation of informal settlements in urban areas. Economic disparities, coupled with limited employment opportunities and affordable housing options, drive migrants and low-income individuals to settle in informal settlements (Davis, 2006). Additionally, land scarcity, high land prices, and restrictive land-use regulations compel marginalized populations to occupy vacant or marginal lands on the urban periphery (Jones & Mberu, 2014). Inadequate access to formal housing finance and lack of affordable housing options further exacerbate the housing crisis, pushing residents towards informal settlements as a coping mechanism (UNDP, 2020).

Residents of informal settlements face a myriad of challenges, ranging from inadequate housing and basic services to social and economic marginalization (Mitlin & Satterthwaite, 2013). The housing in informal settlements is often substandard, comprising makeshift structures constructed from salvaged materials such as corrugated metal, cardboard, and plastic sheets (World Bank, 2019). These precarious housing conditions offer little protection against natural disasters and pose significant health and safety risks to residents (Gulyani & Talukdar, 2008). Moreover, informal settlements typically lack access to basic services such as clean water, sanitation, electricity, and waste management, further compromising the well-being of residents (UNESCO, 2019).

The absence of secure land tenure exacerbates the vulnerabilities of residents in informal settlements, exposing them to forced eviction, land speculation, and displacement (Fernandes & Varley, 2016). Without formal recognition of their rights to the land, residents are unable to invest in improving their housing conditions or accessing essential services (UNICEF, 2020). Furthermore, the stigma associated with informal settlements often leads to social exclusion and discrimination, limiting residents’ access to education, employment, and healthcare (WHO, 2018). These socio-economic challenges perpetuate a cycle of poverty and marginalization, trapping residents in a cycle of vulnerability and deprivation (Adegun et al., 2017).

In essence, informal settlements in urban areas like Gwagwalada Town are complex socio-spatial phenomena shaped by a confluence of economic, social, and political factors. The inadequate housing, lack of basic services, insecure land tenure, and socio-economic marginalization faced by residents underscore the urgent need for interventions aimed at improving the living conditions and well-being of informal settlement communities. By addressing the root causes of informal settlement formation and implementing inclusive and sustainable urban development strategies, policymakers and stakeholders can work towards creating more equitable and resilient cities for all residents.

Urbanization and Informal Settlements

Urbanization is a driving force behind the proliferation of informal settlements, particularly in rapidly growing cities like Gwagwalada Town (Mudau & Mhangara, 2022). As rural populations migrate to urban areas in search of better economic opportunities, the demand for housing often outstrips the supply of formal housing options (Bolund & Hunhammar, 2021). This influx of migrants contributes to the formation of informal settlements on the peripheries of cities, where land is often cheaper and more readily available (Gallagher et al., 2021). Furthermore, inadequate urban planning and regulatory frameworks fail to accommodate the needs of these growing populations, leading to the spontaneous and unplanned development of informal settlements (Morabito et al., 2021).

METHODOLOGY

Introduction

This chapter outlines the methodology employed in conducting the research, focusing on the research design, population of the study, sampling technique and sample size determination, sources and method of data collection, method of data analysis, validity and reliability of the study, and ethical considerations.

Research Design

The research adopted a quantitative survey research design to gather data on environmental quality in informal settlements. This design was chosen for its ability to systematically collect large-scale data from a representative sample of the target population (Saunders, Lewis, & Thornhill, 2019). Given the need to assess environmental conditions comprehensively, a survey approach allowed for the collection of quantitative data on various aspects of environmental quality, such as air and water pollution, waste management practices, and access to green spaces (Bell, Bryman, & Harley, 2019).

Population of the Study

The target population for this study comprised residents of informal settlements in Gwagwalada Town, Nigeria. The justification for this population selection is based on the need to understand the environmental challenges faced by individuals living in these settlements and to inform policy interventions aimed at improving their living conditions (Saunders, Lewis, & Thornhill, 2019). With an estimated population of informal settlements in the study area, the target population of 171 respondents was deemed appropriate for achieving the research objectives.

DATA PRESENTATION, ANALYSIS AND DISCUSSION

Data Presentation

The data presented in Table 4.1 illustrates that out of the total 120 questionnaires distributed, 108 were returned and completed, constituting 90.0% of the total sample. This high response rate indicates a strong level of engagement and willingness among respondents to participate in the study. The substantial proportion of returned and completed questionnaires enhances the reliability of the data collected, suggesting that the research instrument was well-designed and effectively administered. On the other hand, 12 questionnaires were not returned or completed, representing 10.0% of the total sample. While this non-response rate is relatively low, it is essential to acknowledge the potential impact of non-response bias on the study findings.

The high completion rate of the questionnaires underscores the successful implementation of the data collection process and the respondents’ cooperation with the research objectives. Factors such as clear communication, well-structured questionnaires, and possibly follow-up efforts may have contributed to the favourable response rate observed. Despite the overall positive response, it is crucial to consider the potential implications of non-response, as it may introduce bias into the study findings. However, given the small proportion of non-response observed in this study, the potential impact of such bias is likely to be minimal.

SUMMARY, CONCLUSION AND RECOMMENDATIONS

Summary of Findings

The study conducted in Gwagwalada Town aimed to assess various aspects of environmental quality, waste management practices, and community perceptions in informal settlements. Through the analysis of survey data and statistical tests, several key findings emerged, shedding light on the current state of environmental conditions and waste management practices in the area.

Firstly, regarding air quality, the majority of respondents expressed concerns about pollution levels in informal settlements. A significant proportion reported noticing the presence of air pollutants such as smoke and dust, which often led to respiratory issues among residents. Despite efforts to reduce air pollution, a considerable number of respondents felt that the measures were ineffective, indicating ongoing challenges in addressing air quality issues.

Similarly, concerns about water quality were prevalent among residents. While many respondents believed that the water from sources in informal settlements was not safe for drinking, others expressed doubts about the reliability of water sources. This suggests widespread apprehension regarding waterborne diseases and the need for improved water treatment facilities to ensure access to clean and safe drinking water for residents.

In terms of waste management practices, the study revealed a mixed picture. While a majority of respondents perceived waste management systems to be well-organized and efficient, there were concerns about the segregation of waste before disposal. Notably, improper waste disposal was identified as a significant contributor to environmental pollution in informal settlements, highlighting the need for better waste management strategies and infrastructure.

Furthermore, the availability of waste recycling facilities was perceived differently among residents. While some believed that adequate recycling facilities were accessible, others expressed doubts about their availability, indicating potential gaps in recycling infrastructure. This underscores the importance of enhancing recycling initiatives and improving access to recycling facilities to promote sustainable waste management practices.

Statistical analyses, including one-sample t-tests, provided further insights into residents’ perceptions of environmental quality and waste management practices. The results indicated significant differences in perceptions compared to an assumed norm, emphasizing the need for targeted interventions to address environmental challenges effectively.

Overall, the findings of the study underscore the complex nature of environmental issues in informal settlements and the importance of holistic approaches to address them. Effective strategies should focus not only on improving environmental quality but also on enhancing waste management systems, promoting community engagement, and fostering sustainable practices. By incorporating residents’ perspectives and experiences, policymakers and stakeholders can develop more inclusive and impactful interventions to create healthier and more sustainable living environments in informal settlements.

Conclusion

The results of the hypotheses testing provide valuable insights into the environmental conditions and challenges faced by informal settlements in Gwagwalada Town. Through rigorous statistical analysis, several key conclusions can be drawn regarding air, water, and soil pollution levels, as well as the prevalence of environmental hazards and the adequacy of existing management practices.

Firstly, the findings suggest that there are significant differences in pollution levels between informal settlements and formal residential areas. Residents of informal settlements are more likely to experience higher levels of air, water, and soil pollution, which can have adverse effects on their health and well-being. This highlights the urgent need for targeted interventions to improve environmental quality in these areas.

Secondly, the results indicate that environmental hazards and risks are indeed more prevalent in informal settlements compared to formal residential areas. The higher prevalence of air and water pollution, coupled with inadequate waste management practices, exacerbates environmental risks for residents living in these settlements. Efforts to mitigate these risks should prioritize the development of comprehensive environmental management strategies tailored to the unique needs of informal settlements.

Finally, the study suggests that existing environmental management practices and policies are insufficient in addressing the challenges faced by informal settlements. While some efforts have been made to reduce pollution and improve waste management, the results indicate that these measures are not adequately meeting the needs of residents. There is a clear need for more robust and effective environmental policies, backed by increased investment in infrastructure and community engagement initiatives.

In conclusion, the findings underscore the urgent need for comprehensive and targeted interventions to improve environmental quality and mitigate hazards in informal settlements. Addressing the complex challenges faced by these communities requires a multifaceted approach that involves collaboration between government agencies, non-governmental organizations, and local communities. By implementing evidence-based policies and interventions, stakeholders can work towards creating healthier and more sustainable living environments for residents of informal settlements in Gwagwalada Town and similar areas.
