CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Household waste management is an important component of environmental health and community health. Every household generates waste through cooking, food consumption, cleaning, packaging, personal activities and the use of domestic products. When these wastes are properly stored, collected, transported, treated and disposed of, the risks to human health and the environment can be substantially reduced. However, when household waste is indiscriminately dumped, burned in the open, deposited in drains or waterways, or left uncollected for long periods, it can become an important environmental health hazard. The World Health Organization (WHO, 2022) identifies improper solid-waste management as a source of soil, water and air contamination and notes that poorly managed waste can block drainage systems, contribute to flooding and create conditions favourable for vector-borne and other diseases.

Globally, the challenge of solid waste management has become more serious because of population growth, urbanisation, increasing consumption and changing patterns of production. The World Bank has reported that municipal solid waste generation is increasing rapidly, while low- and middle-income countries face particular difficulties with collection and environmentally safe disposal. Open dumping remains common in many developing settings, with consequences for environmental quality and human health. Poorly managed waste can pollute water and soil, attract disease vectors and clog storm-water drainage systems, thereby increasing the risk of flooding and exposure to contaminated environments (Kaza et al., 2018).

From a community health perspective, household waste is important because health is influenced not only by healthcare services but also by the physical and social environment in which people live. Environmental conditions such as sanitation, water quality, drainage, housing and waste management can influence exposure to infectious diseases and other health hazards. The WHO (2022) notes that poorly managed waste may create standing water and breeding conditions for vectors, while unsafe burning may expose residents to harmful air pollutants. Children and other vulnerable groups may be particularly susceptible to some of these exposures.

Household waste can contain biodegradable materials, plastics, paper, glass, metals, textiles, domestic chemicals, sanitary materials and electronic waste. The mixture of different materials creates different health and environmental risks. Organic waste can decompose and produce unpleasant odours while attracting flies, rodents and other organisms. Plastics may obstruct drainage channels and persist in the environment for long periods. Electronic waste may contain hazardous substances that can cause health problems when improperly handled. WHO (2024) identifies e-waste as a rapidly growing domestic waste stream and highlights the particular vulnerability of children to toxic exposures associated with inappropriate e-waste handling and recycling.

Improper waste disposal can therefore affect health through several pathways. Direct contact with contaminated waste can expose individuals to microorganisms and hazardous materials. Waste dumped in drains can contribute to stagnant water and flooding, creating favourable conditions for mosquitoes and other vectors. Waste deposited close to food sources or water bodies can contribute to contamination. Open burning can release smoke and particulate matter into the surrounding environment. The WHO (2021) emphasises that waste-management options and waste sites can have important consequences for health and wellbeing, particularly for people living or working around poorly managed waste sites.

The problem is particularly relevant in rapidly growing African cities. Urbanisation can place considerable pressure on existing waste-management systems. As populations increase, the quantity of waste generated by households also increases, while waste collection infrastructure may not expand at the same rate. The WHO (2024) identifies rapid urbanisation, population growth, high management costs and weak governance systems as important pressures affecting solid waste management. Inadequate collection, recovery and disposal services can contribute to recurring environmental and health problems.

Nigeria faces significant challenges in the management of municipal and household solid waste. Rapid urban development, population growth, inadequate collection facilities, insufficient public awareness and inconsistent enforcement of environmental regulations can contribute to poor waste disposal practices. The situation is particularly important in densely populated urban communities where large quantities of household waste are generated daily.

Port Harcourt, the capital of Rivers State and a major commercial and industrial centre in the Niger Delta, provides an important setting for examining household waste disposal and community health. The city’s population growth and urban expansion have increased pressure on environmental infrastructure. Previous research has identified persistent problems involving indiscriminate dumping, inadequate waste collection and disposal in open spaces and waterways.

Stanley and Owhor (2018), in their assessment of solid waste management in Port Harcourt metropolis, found that residents used different disposal methods, including roadside dumping, communal storage and collection vehicles. The study also reported the persistence of open dumping and disposal in waterways and identified poor implementation, weak enforcement and inadequate awareness as important challenges to effective waste management.

The problem is not limited to the visual appearance of communities. Wokekoro and Inyang (2014) examined waste disposal practices in informal settlements in Port Harcourt and highlighted the health implications of inadequate household and human-waste disposal systems. Their study of waterfront settlements drew attention to the absence of adequate sanitation and waste-management infrastructure and the potential consequences for residents’ health.

Similarly, Tamunobereton-ari, Omubo-Pepple and Igbani (2012) examined solid-waste management in Port Harcourt municipality and reported deficiencies in storage and collection systems. Their findings indicated that many storage facilities were substandard and insanitary and that waste handling could contribute to soil and surface-water pollution. The study demonstrates that waste management in Port Harcourt is not simply an environmental issue but also a public health concern.

The relationship between household waste and environmental contamination has also been documented in Port Harcourt. A study published in Management of Environmental Quality examined household waste impacts on physicochemical characteristics of surface water, soil, sediments and borehole water in Port Harcourt. The study reported that household wastes were indiscriminately deposited on roads, stream channels, bushlands and open spaces, contributing to pollution, flooding and conditions associated with vector-borne diseases.

Research in the wider Port Harcourt metropolis has further connected irregular dumpsites with disease occurrence. A study published in Sustainable Environment Research examined the spatial relationship between irregular dumpsites and disease incidence in Obio-Akpor, within the Port Harcourt metropolitan area. The researchers found a statistically significant relationship between the presence of dumpsites and reported incidences of cholera, diarrhoea and malaria, highlighting the potential public-health implications of poorly managed household waste (Nwankwoala et al., 2020).

Recent evidence from Port Harcourt also reinforces the continuing relevance of the problem. A 2025 study of Rivers State waste-management practices involving residents in Port Harcourt and its environs examined household access to collection services, infrastructure adequacy, collection frequency, safety compliance and equity of service delivery. The study demonstrates that waste collection remains an important concern for residents and that the effectiveness of waste-management systems cannot be separated from household experiences and community participation (Okoro & Ogboeli, 2025).

Household behaviour is another important dimension of the problem. Waste-management systems depend not only on government agencies and private contractors but also on the behaviour of individual households. Households determine how waste is stored, whether materials are separated, how waste is transported to collection points and whether waste is disposed of in approved locations. Where households lack appropriate storage containers or reliable collection services, indiscriminate disposal may become more common.

There may also be a gap between knowledge and actual waste-disposal behaviour. Residents may understand that improper waste disposal is harmful while continuing to dump refuse in open spaces because of inadequate collection services, cost, convenience or social norms. This indicates that health education alone may not solve the problem unless it is supported by accessible and reliable waste-management infrastructure.

The availability of waste-collection services is therefore an important factor in household disposal practices. Where collection services are irregular, households may retain waste for extended periods or resort to alternative disposal methods such as roadside dumping or burning. Conversely, reliable and affordable collection services can encourage households to dispose of waste through safer channels. Effective community health interventions must therefore consider both individual behaviour and structural conditions.

Open burning is another significant concern. Residents sometimes burn household waste to reduce its volume or because collection services are unavailable. Although burning may appear to provide a quick solution, it can expose residents to smoke and pollutants. The WHO (2022) identifies unsafe waste treatment such as open burning as a source of health risks for people living near waste-burning locations and for waste workers.

Waste disposal also has implications for flooding in urban communities. Plastic bags, bottles and other materials can enter drainage channels and restrict the movement of storm water. During periods of heavy rainfall, blocked drains may contribute to stagnant water and flooding. The resulting environmental conditions may increase exposure to contaminated water and provide breeding habitats for mosquitoes and other vectors. The World Bank similarly identifies blocked storm-water drains as an important pathway through which poor waste management can contribute to flooding and unhealthy environmental conditions.

For a community health study, it is therefore important to move beyond simply describing the amount of waste generated. Attention should be given to household storage practices, methods of disposal, frequency of collection, availability of waste facilities, household knowledge, environmental sanitation and perceived health consequences. Such an approach provides a more complete understanding of how waste-disposal practices affect community health.

The current study is particularly important because existing evidence from Port Harcourt has demonstrated substantial waste-management problems, but conditions may vary between communities. Differences in housing density, socioeconomic conditions, availability of waste-collection services, drainage infrastructure and proximity to disposal sites may influence household practices and health risks. Consequently, examining selected communities within Port Harcourt City Local Government Area can provide community-level evidence that may support more targeted environmental health interventions.

The study also recognises that waste management is a shared responsibility. Government agencies, local authorities, private waste contractors, households, community leaders, health workers and environmental organisations all have roles to play. Effective waste management requires appropriate infrastructure, regular collection, public education, enforcement of regulations, community participation and monitoring.

The community health perspective is especially important because preventing environmental exposure is generally preferable to treating diseases after they occur. If improper waste disposal contributes to vector breeding, water contamination, air pollution and unhealthy living environments, improving household waste practices can form part of a broader disease-prevention strategy. Environmental sanitation is therefore an important component of primary healthcare and health promotion.

Against this background, this study seeks to evaluate household waste disposal practices and their effects on community health in selected communities in Port Harcourt City Local Government Area, Rivers State. The study will assess the common methods used by households to dispose of waste, examine factors influencing disposal practices, identify perceived and observable environmental health problems associated with poor waste disposal, and determine the relationship between household waste disposal practices and selected community-health outcomes.

1.2 Statement of the Problem

Household waste generation is an unavoidable consequence of human activity, but the health consequences depend significantly on how the waste is managed. In an urban environment such as Port Harcourt, the continuous generation of household waste creates a need for effective storage, collection, transportation and final disposal. However, evidence from previous studies indicates that open dumping, roadside disposal, disposal in waterways and other unsafe practices continue to occur in parts of the metropolis. Stanley and Owhor (2018) found that open dumping and disposal in waterways persisted despite the existence of waste-management agencies and contractors.

The problem is particularly serious because indiscriminate disposal does not merely create an unattractive environment. Waste accumulation can attract flies, rodents and other vectors, produce offensive odours, contaminate soil and water, obstruct drainage channels and contribute to flooding. WHO (2022) recognises these pathways as important environmental health concerns associated with poor waste management.

Port Harcourt has experienced persistent waste-management challenges despite interventions by government and other stakeholders. Previous research has identified inadequate storage facilities, insufficient collection, open dumping and poor enforcement as important challenges. Tamunobereton-ari et al. (2012) reported significant deficiencies in waste storage and collection systems in Port Harcourt municipality, while Stanley and Owhor (2018) identified weak implementation, enforcement and public awareness as major problems.

The health implications are particularly concerning. Research from the Port Harcourt metropolitan area has associated irregular dumpsites with diseases such as malaria, diarrhoea and cholera, while other studies have documented environmental contamination associated with household waste. These findings suggest that household waste disposal should be regarded as a community-health issue rather than solely as an environmental-management problem.

Another dimension of the problem is the apparent gap between knowledge and practice. Even when residents understand the dangers of indiscriminate waste disposal, they may continue to engage in unsafe practices because of inadequate collection services, inconvenient disposal locations, cost, poor enforcement or established community habits. Consequently, the presence of environmental health knowledge does not necessarily guarantee safe household waste-disposal behaviour.

Furthermore, the availability and reliability of waste-management services may differ from one community to another. Some households may have access to regular collection services, while others may depend on communal disposal points or informal methods. Such differences can influence the quantity of waste accumulated around residential areas and the degree of exposure to environmental hazards.

Open burning also presents a significant concern. Households may burn waste when collection is unavailable or irregular. This practice can release smoke and pollutants into the local environment and expose household members and neighbours to respiratory hazards. WHO (2021) notes that waste-management practices can have important effects on air quality and health, especially among people living or working around waste sites.

The problem is further complicated by the changing composition of household waste. Modern households increasingly generate plastic packaging, electronic waste, batteries, synthetic materials and other products that may be difficult to manage safely through conventional disposal methods. The inappropriate handling of e-waste is of particular concern because of its potential toxic exposures and the vulnerability of children to some associated substances (WHO, 2024).

Although previous studies have examined waste management in Port Harcourt and surrounding areas, there remains a need for community-level assessment of current household practices and their relationship with community health. Waste-management conditions can change over time because of population growth, changes in collection arrangements, environmental policies and household behaviour. Therefore, findings from earlier studies should not automatically be assumed to represent present conditions in every community.

The central problem addressed by this study is therefore the continued existence of potentially unsafe household waste-disposal practices in selected communities in Port Harcourt City Local Government Area and the possible consequences of such practices for community health. Without reliable evidence concerning current household practices and associated health effects, interventions may fail to address the specific behavioural and infrastructural factors responsible for the problem.

It is against this background that this study seeks to evaluate household waste disposal practices and their effects on community health in selected communities in Port Harcourt City Local Government Area, Rivers State. The findings are expected to provide evidence that can assist health educators, community health practitioners, environmental health officers, local authorities, waste-management agencies and community leaders in developing appropriate interventions for healthier and more sustainable communities.

1.3 Aim of the Study

The main aim of this study is to evaluate household waste disposal practices and their effects on community health in selected communities in Port Harcourt City Local Government Area, Rivers State.

1.4 Objectives of the Study

The specific objectives are to:

1. assess the common household waste disposal practices among residents of selected communities in Port Harcourt City Local Government Area;
2. determine the level of knowledge of residents concerning the health risks associated with improper household waste disposal;
3. identify the environmental and health problems associated with improper household waste disposal in the selected communities;
4. examine the factors influencing household waste disposal practices among residents; and
5. determine the relationship between household waste disposal practices and selected community-health outcomes in the study area.

1.5 Research Questions

The study will be guided by the following research questions:

1. What are the common household waste disposal practices among residents of selected communities in Port Harcourt City Local Government Area?
2. What is the level of knowledge of residents concerning the health risks associated with improper household waste disposal?
3. What environmental and health problems are associated with improper household waste disposal in the selected communities?
4. What factors influence household waste disposal practices among residents?
5. What relationship exists between household waste disposal practices and selected community-health outcomes in the study area?

1.6 Research Hypothesis

The following null hypothesis will be tested at the 0.05 level of significance:

H₀: There is no significant relationship between household waste disposal practices and selected community-health outcomes among residents of selected communities in Port Harcourt City Local Government Area, Rivers State.

1.7 Significance of the Study

The study will be significant to community health practitioners because it will provide information about the environmental conditions that may influence the health of residents. Community health workers can use the findings to design health-education programmes that address household waste storage, disposal, sanitation, vector control and disease prevention.

The study will also be useful to residents of the selected communities. It may increase awareness of the health consequences associated with indiscriminate waste disposal and encourage households to adopt safer methods of waste storage and disposal.

The findings will be relevant to Rivers State waste-management authorities and other environmental agencies. Evidence concerning household disposal practices can help such agencies identify gaps in waste collection and disposal services and develop strategies for improving coverage and efficiency.

Local government authorities may also benefit from the study. Since local communities are directly affected by waste accumulation, the findings may support decisions concerning waste-collection points, sanitation campaigns, drainage maintenance, environmental enforcement and community mobilisation.

The study will be useful to healthcare providers because it will highlight the potential relationship between environmental sanitation and community health. Healthcare professionals can incorporate environmental-health education into routine community outreach and disease-prevention activities.

The study will also benefit researchers and students in community health, public health, environmental health and related disciplines. It will contribute to the body of knowledge on household waste management and environmental health in an urban Nigerian setting and may serve as a reference for future research.

Finally, the study will be relevant to community leaders and civil-society organisations. It can encourage community participation in sanitation activities, environmental monitoring and advocacy for improved waste-management infrastructure.

1.8 Scope of the Study

The study focuses on the evaluation of household waste disposal practices and their effects on community health in selected communities in Port Harcourt City Local Government Area, Rivers State.

The study will specifically examine household methods of waste storage and disposal, frequency of waste disposal, access to waste-collection services, waste-segregation practices, open dumping, open burning, disposal in drainage channels and other relevant practices. It will also assess residents’ knowledge of the health consequences of improper waste disposal and selected community-health outcomes that may be associated with poor environmental sanitation.
