Project – Household Waste Disposal Practices and the Risk of Mosquito-Borne Diseases in Urban Communities: A Study of Selected Households in Port Harcourt City Local Government Area, Rivers State

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Environmental sanitation is an important component of public health because the condition of the physical environment influences exposure to infectious diseases and the quality of life of individuals and communities. Among the environmental factors with direct implications for health is the manner in which household solid waste is generated, stored, collected, transported and finally disposed of. Household waste consists of materials discarded from domestic activities, including food remnants, plastics, cans, bottles, papers, discarded containers, tyres and other materials. When such materials are not properly managed, they may accumulate within residential environments, block drainage channels and create conditions that support the proliferation of disease vectors. In tropical urban settings, poor waste management is particularly important because discarded materials can retain rainwater and create small aquatic habitats suitable for mosquito breeding.

Mosquitoes are among the most important vectors of infectious diseases worldwide. They transmit diseases such as malaria, dengue, yellow fever, chikungunya and lymphatic filariasis. The public health importance of mosquito control is especially pronounced in sub-Saharan Africa, where malaria remains a major cause of illness and death. The World Health Organization (WHO, 2024) reported that the African Region continues to account for the overwhelming majority of global malaria cases and deaths. Nigeria remains one of the countries carrying a particularly large share of the global malaria burden. The WHO Nigeria malaria country profile reported an estimated 68.1 million malaria cases and approximately 184,700 malaria deaths for 2023, demonstrating the continuing importance of malaria prevention and vector control in the country.

The persistence of malaria and other mosquito-borne diseases means that disease prevention cannot depend exclusively on diagnosis and treatment. Vector control and environmental management remain essential components of prevention. The WHO (2012) explains that larval source management involves the targeted management of mosquito breeding sites to reduce mosquito larvae and pupae. Environmental management therefore complements measures such as insecticide-treated nets, indoor residual spraying and other vector-control interventions. More recently, the WHO has emphasized that container and waste management can form part of larval source management because discarded objects capable of collecting water can provide mosquito breeding habitats.

The relationship between solid waste and mosquito proliferation can be understood from the ecological characteristics of mosquitoes. Mosquitoes require water for their immature stages, although the specific breeding preferences differ among species. Household refuse can create artificial water-holding containers within residential environments. Discarded tyres, cans, bottles, plastic containers, broken household materials, blocked gutters and other receptacles may collect rainwater. Where such materials remain undisturbed for sufficient periods, they may become suitable breeding habitats. Consequently, waste disposal is not merely an aesthetic or environmental issue; it can become a component of the ecological pathway through which vector populations are sustained.

The WHO has recognized solid waste as one of the environmental conditions capable of contributing to mosquito breeding. Its environmental health guidance identifies discarded tyres, food containers and other solid waste that can collect rainwater as potential mosquito breeding sites. The same guidance stresses the importance of waste management and urban environmental management in source reduction. This is particularly significant in urban communities where population density, housing patterns, drainage conditions, rainfall and human activities interact to create complex environmental conditions.

Urbanization increases the importance of effective household waste management. Rapidly expanding urban populations generate substantial quantities of domestic waste, while waste collection systems may not always expand at the same rate as population growth. The result may include irregular collection, overflowing waste receptacles, indiscriminate dumping and disposal of refuse in drains and other unauthorized locations. Such practices can contribute to environmental degradation and potentially increase opportunities for mosquito breeding. The WHO notes that urban areas have distinctive malaria transmission dynamics because of their environmental and socioeconomic conditions and recommends attention to environmental management, drainage and sanitation as supplementary components of urban malaria control.

Nigeria’s urban environment presents several challenges in this regard. The combination of population growth, urban expansion, inadequate waste infrastructure, poor drainage and changing patterns of household consumption has increased the quantity and variety of solid waste produced in many cities. Port Harcourt, the capital of Rivers State and a major commercial and industrial centre in the Niger Delta, provides an important setting for examining these issues. The city’s extensive residential areas, commercial activities, transportation networks, drainage systems and tropical rainfall conditions create an environment in which waste management and mosquito control are closely connected.

Studies conducted in Port Harcourt have documented persistent challenges associated with solid waste management. Stanley and Owhor (2018), in their assessment of solid waste management practices in Port Harcourt Metropolis, found that residents used several disposal methods, including roadside dumping, communal storage and collection vehicles. The study also reported the persistence of open dumping and disposal of waste in waterways and characterized aspects of the city’s waste disposal system as unsafe. The authors identified poor implementation, inadequate enforcement and insufficient environmental awareness as important challenges to effective waste management in the metropolis.

Similarly, Binafeigha and Enwin (2017) observed that solid waste management in Port Harcourt was characterized by practices such as burning, disposal in open dumps and disposal into water bodies. They argued that waste management in the city had not consistently achieved the organized and systematic handling of waste required for environmental and public health protection. Earlier research by Igoni et al. (2007) also demonstrated that although substantial quantities of municipal solid waste were generated and collected in Port Harcourt, some waste remained as litter, while open burning and other disposal practices created environmental hazards.

The problem is not limited to the general condition of the city; household behaviour is an important component of the waste-management chain. The way households store waste before collection, the frequency with which waste is removed, whether waste is disposed of through authorized collection services, and whether residents dump waste in drains, vacant spaces or waterways can determine the extent to which refuse accumulates around homes. Household practices can therefore influence whether discarded materials remain exposed to rainfall and become potential mosquito breeding containers.

Arimieari, Sangodoyin and Joe (2014) reported that there was no organized pattern of waste disposal across different parts of Port Harcourt and that indiscriminate disposal into open drains was particularly prevalent in some residential areas. Their findings demonstrate that household and community disposal behaviour is an important dimension of the city’s environmental sanitation challenge. Where waste is deposited in open drains, for example, it may obstruct water flow and contribute to stagnant water. Similarly, plastics, cans, tyres and other discarded materials may collect rainwater after being deposited in open spaces.

The connection between waste accumulation, stagnant water and mosquito breeding is important because mosquitoes are not generated by waste itself. Rather, some types of waste create or facilitate water-holding environments in which mosquito larvae can develop. This distinction is important for public health interventions. Simply removing visible refuse may not be sufficient if standing water, blocked drainage and uncovered containers remain. Effective environmental management therefore requires attention to the entire household environment, including waste storage, disposal, drainage, water containers and the removal of potential breeding sites.

Evidence from other Nigerian urban settings supports the importance of household environmental practices in mosquito control. Adeleke et al. (2023), in a study of urban informal settlements in Lagos State, examined knowledge, attitudes and practices related to mosquito control. The study found that respondents reported several environmental practices, including clearing gutters and covering or draining water-holding domestic containers. It also documented different waste-disposal routes within the communities and demonstrated that community context was associated with waste disposal practices and other mosquito-control behaviours.

The issue is particularly important in relation to malaria. Malaria is transmitted through the bite of infected female Anopheles mosquitoes. The major malaria vectors in Nigeria include members of the Anopheles gambiae complex and Anopheles funestus group. The WHO’s Nigeria country profile identifies Anopheles gambiae sensu lato, Anopheles funestus sensu lato and Anopheles arabiensis among the major malaria vector species. Although malaria transmission involves complex interactions between mosquitoes, parasites, humans and environmental conditions, the availability and management of mosquito breeding habitats remain relevant to vector abundance and control.

Other mosquito-borne diseases also warrant attention. Aedes mosquitoes, for example, are associated with diseases such as dengue, yellow fever and chikungunya and are particularly adapted to breeding in artificial containers around human settlements. The increasing recognition of container-breeding mosquitoes makes household environmental management an important consideration even where malaria is the dominant mosquito-borne disease. The WHO’s 2026 operational manual on larval source management specifically expanded its guidance to include Aedes mosquitoes and related arboviral diseases and identified container and waste management among the intervention approaches that can contribute to mosquito control.

The relationship between waste and disease has also received attention in studies conducted specifically around Port Harcourt. A recent study by Nmeribe et al. (2026) examined waste disposal and the occurrence of malaria and diarrhoea in Port Harcourt Local Government Area. The researchers studied four communities and combined questionnaires, field observations and entomological surveys. They reported open dumping and burning among common waste-disposal methods and found substantial mosquito abundance around some dumpsites. They also reported an association between poor waste disposal and malaria occurrence, with households practising open dumping reporting particularly high malaria occurrence. Importantly, the study identified a gap between knowledge and actual waste-management practices among residents.

The findings of Nmeribe et al. (2026) are highly relevant to the present study because they provide recent local evidence that waste disposal and mosquito-related health risks are not merely theoretical concerns in Port Harcourt. However, the present study approaches the issue from a specifically household-centred perspective. Rather than concentrating primarily on disease occurrence around selected communities and dumpsites, the present study seeks to examine the waste disposal practices of selected households and how such practices may create environmental conditions associated with mosquito-borne disease risk.

There is also evidence from the wider Niger Delta region that waste accumulation and irregular dumpsites have public health implications. A study of irregular household waste dumpsites in the Niger Delta reported that disease occurrence in the Obio-Akpor area of the Port Harcourt metropolis was associated with the distribution and proximity of irregular dumpsites. The study identified a significant relationship between disease incidence and the presence of dumpsites, illustrating how the spatial distribution of poorly managed waste may interact with environmental and health conditions.

Household waste disposal practices are influenced by several factors. These include environmental knowledge, household income, availability and affordability of waste collection services, distance to authorized disposal points, frequency of waste collection, community norms, enforcement of environmental regulations and perceptions concerning the consequences of improper disposal. Even when households understand that indiscriminate dumping is harmful, inadequate collection infrastructure may limit their ability to practise appropriate waste management. Conversely, the availability of waste collection services may not automatically guarantee proper disposal if households do not use the services consistently.

Consequently, understanding household waste disposal requires consideration of both individual behaviour and the broader environmental system. A household may store waste properly but dispose of it at an unauthorized location because formal collection services are unavailable. Another household may have access to collection services but continue to dispose of refuse in drains or open spaces because of convenience, cost or established community practices. These circumstances demonstrate that household waste disposal is a behavioural, infrastructural and environmental health issue.

The public health importance of this problem is heightened by the persistence of malaria in Nigeria. WHO data continue to identify Nigeria as one of the countries with the greatest malaria burden globally. The 2025 WHO malaria reporting further emphasized that malaria remains a major global health challenge, with the African Region carrying the largest share of the burden. Nigeria therefore requires multiple complementary approaches to malaria prevention, including effective vector control, appropriate environmental sanitation and community participation.

Vector control has traditionally emphasized interventions such as insecticide-treated nets and indoor residual spraying. These interventions remain central to malaria control, but environmental management can provide additional support by reducing mosquito breeding opportunities. The WHO describes vector control as a vital component of malaria prevention and recognizes larval source management as a supplementary intervention in appropriate settings. This suggests that improving household waste disposal should not be viewed as a substitute for established malaria interventions but as part of a broader integrated environmental and vector-control strategy.

Port Harcourt City Local Government Area provides a relevant context for such an investigation because it combines dense residential development, commercial activity, extensive household waste generation and tropical environmental conditions. Poorly disposed refuse may interact with blocked drainage systems and standing water, especially during and after rainfall. Where residents dispose of containers, tyres, plastics and other water-holding materials around homes, these materials may provide additional opportunities for mosquito breeding.

The significance of examining households is further strengthened by the fact that environmental health outcomes are often produced through repeated everyday practices. Waste is generated every day, stored temporarily, transported or disposed of, and potentially left exposed in the residential environment. Thus, a household’s disposal behaviour can produce cumulative environmental consequences. When many households within the same community engage in inappropriate disposal practices, the resulting accumulation of waste can transform the broader residential environment.

The present study therefore focuses on the relationship between household waste disposal practices and the risk of mosquito-borne diseases in selected urban communities of Port Harcourt City Local Government Area, Rivers State. The study is concerned not only with whether households dispose of waste properly but also with the forms of disposal they use, the environmental conditions created by those practices, the presence of potential mosquito breeding sites, and the extent to which residents perceive or experience mosquito-borne disease risks.

The study is important because controlling mosquito-borne diseases requires interventions that address environmental conditions as well as individual protection. By examining household practices, the research can provide evidence that may be useful to environmental health officers, public health practitioners, local government authorities, waste management agencies and community organizations. The evidence may also help identify specific household behaviours that require attention through environmental health education and community-based vector-control programmes.

1.2 Statement of the Problem

Mosquito-borne diseases remain a major public health concern in Nigeria despite continuing efforts directed at prevention, diagnosis, treatment and vector control. Malaria, in particular, places a substantial burden on households and the health system. Nigeria continues to account for a very large proportion of global malaria cases and deaths, making environmental and vector-control interventions an important part of the national public health response.

One of the environmental issues that may contribute to mosquito proliferation in urban communities is poor household waste disposal. In an ideal waste-management system, household refuse is stored in suitable containers, collected at appropriate intervals and transported to authorized treatment or disposal facilities. In practice, however, some households may dispose of refuse in open spaces, road margins, drains, waterways, vacant plots or unauthorized dumpsites. Such practices can result in the accumulation of materials capable of retaining water and can contribute to the obstruction of drainage channels.

The problem is particularly relevant in Port Harcourt. Research on solid waste management in the city has repeatedly documented the persistence of inappropriate disposal practices. Stanley and Owhor (2018) reported roadside dumping, communal dumping and other disposal practices, while open dumping and dumping in waterways continued to occur. Binafeigha and Enwin (2017) similarly observed the burning and disposal of waste in open dumps and water bodies. These findings suggest that, despite the existence of waste-management structures, the disposal of household waste remains an environmental challenge in the metropolis.

The concern goes beyond the unpleasant appearance of accumulated waste. Certain forms of household refuse can retain rainwater and create potential breeding habitats for mosquitoes. Discarded tyres, cans, bottles, plastics and other containers may become temporary water reservoirs. When these materials remain around homes or in open dumps, they may contribute to the creation of mosquito breeding sites. The WHO recognizes waste and water-holding containers as potential components of mosquito breeding environments and recommends environmental and larval source management as supplementary approaches to vector control.

A further problem is that residents may not always recognize the relationship between household waste disposal and mosquito breeding. Many people understand mosquitoes primarily in terms of biting and disease transmission but may not recognize that everyday disposal practices can influence the availability of mosquito breeding habitats. A household may therefore use mosquito nets or insecticides while simultaneously maintaining environmental conditions that favour mosquito breeding. This creates a potential contradiction between personal protection and environmental prevention.

Evidence from Nigerian urban communities demonstrates that knowledge does not necessarily translate automatically into appropriate environmental behaviour. Adeleke et al. (2023), for example, found that residents of informal settlements in Lagos had considerable awareness of mosquitoes and their breeding environments, yet waste-disposal and other environmental-control practices varied across communities. Similarly, the recent Port Harcourt study by Nmeribe et al. (2026) found a gap between knowledge about waste management and actual good waste-management practices. This knowledge-practice gap raises an important public health question: to what extent are household disposal behaviours contributing to environmental conditions that may increase mosquito-borne disease risk?

Another problem concerns the adequacy and consistency of waste collection services. Improper household disposal may sometimes be attributed to individual behaviour, but households operate within a broader waste-management system. Where collection services are irregular, inaccessible or unaffordable, residents may resort to informal disposal methods. Arimieari et al. (2014) identified indiscriminate disposal into open drains among the waste-management challenges observed in Port Harcourt. This suggests that household waste disposal behaviour must be examined in relation to the availability of environmental sanitation infrastructure.

The accumulation of refuse around residential areas may also interact with Port Harcourt’s drainage and rainfall conditions. When plastic materials, bottles, food containers and other waste enter drains, they can contribute to blockage and stagnant water. Although waste does not directly cause malaria, it can contribute indirectly by creating or maintaining environmental conditions suitable for mosquitoes. Therefore, the public health problem is not simply the presence of waste but the interaction between waste, water accumulation, mosquito breeding and human exposure.

There is growing evidence that the spatial proximity of poorly managed waste to residential areas may have health consequences. In the Port Harcourt metropolis, research on irregular dumpsites found a significant relationship between disease incidence and the presence of dumpsites. The 2026 study specifically conducted in Port Harcourt Local Government Area also reported high mosquito abundance around some waste dumpsites and an association between open dumping and malaria occurrence. These findings make it necessary to investigate the household-level practices that contribute to the creation and persistence of such environmental conditions.

Despite these findings, important questions remain concerning how individual households in selected urban communities manage their waste. It is necessary to establish the common methods used by households, the frequency of waste disposal, the availability and use of formal waste collection services, the extent of indiscriminate dumping, and the presence of waste-related mosquito breeding opportunities around residential premises. Without such information, environmental health interventions may focus broadly on waste management without adequately addressing the specific household behaviours responsible for continued environmental exposure.

There is also a need to distinguish between perceived mosquito-borne disease risk and actual environmental risk. Residents may perceive mosquitoes as a nuisance without understanding the disease implications of breeding sites around their homes. Others may consider malaria unavoidable because it is common in the community and consequently pay insufficient attention to environmental prevention. Investigating residents’ practices alongside environmental conditions can therefore provide a more complete understanding of the problem.

The problem is further complicated by the fact that mosquito-borne disease risk is influenced by several factors beyond waste disposal. Housing quality, stagnant water from other sources, rainfall, drainage, mosquito-control practices, socioeconomic conditions and access to healthcare may all influence disease risk. Consequently, the present study does not assume that poor waste disposal alone causes mosquito-borne diseases. Rather, it seeks to determine whether household waste disposal practices are associated with environmental conditions that may increase exposure to mosquitoes and thereby contribute to mosquito-borne disease risk.

The recent study by Nmeribe et al. (2026) provides valuable evidence on the association between waste disposal and malaria in Port Harcourt Local Government Area. However, its focus included malaria and diarrhoea occurrence and entomological observations across selected communities. The present research gives particular attention to household waste disposal practices as an environmental and behavioural pathway associated with mosquito-borne disease risk. This distinction is important because interventions aimed at reducing household-level risk require knowledge of what residents actually do with their waste, rather than disease occurrence data alone.

The absence of consistent household-level evidence can make it difficult for public health authorities and local government environmental health departments to determine which practices require priority intervention. For instance, if open dumping is widespread, intervention may require stronger waste collection and enforcement. If the major problem is temporary household storage in uncovered containers, health education and improved storage facilities may be more appropriate. If blocked drains are strongly associated with waste disposal, community sanitation and drainage management may need greater emphasis.

The public health implications of failing to address these issues are considerable. Persistent mosquito breeding can increase nuisance biting and potentially increase exposure to mosquito-borne infections. Repeated malaria episodes can impose financial costs on households through treatment expenses, transportation and lost work or school time. At the community level, persistent environmental degradation may undermine quality of life and increase pressure on health services.

Therefore, the central problem addressed by this study is the possibility that inappropriate household waste disposal practices in selected urban communities of Port Harcourt City Local Government Area may contribute to environmental conditions favourable to mosquito breeding and thereby increase the risk of mosquito-borne diseases. The study seeks to generate empirical evidence on the disposal practices of households and their relationship with mosquito-borne disease risk. Such evidence is necessary for designing practical household, community and local-government interventions that combine improved waste management with environmental mosquito control.

1.3 Aim of the Study

The main aim of this study is to examine the relationship between household waste disposal practices and the risk of mosquito-borne diseases among selected households in Port Harcourt City Local Government Area, Rivers State.

H₀: There is no significant relationship between household waste disposal practices and the risk of mosquito-borne diseases among selected households in Port Harcourt City Local Government Area, Rivers State.

1.7 Significance of the Study

The study will be significant to several groups.

Public Health Practitioners

The findings will provide public health practitioners with evidence concerning the relationship between household environmental practices and mosquito-borne disease risk. Such information can support the design of environmental health education programmes that address specific household behaviours rather than relying solely on general sanitation messages.

Environmental Health Officers

Environmental health officers may use the findings to identify common disposal practices that require intervention. The study may assist in developing community inspection, sanitation education and vector-control programmes that focus on household-level sources of environmental risk.

Port Harcourt City Local Government Authority

The findings may assist the local government in understanding household waste-management challenges within selected communities. The evidence could support decisions concerning waste collection points, collection frequency, environmental sanitation campaigns and enforcement of relevant sanitation regulations.

Waste Management Agencies

The study may provide useful information concerning residents’ use of formal waste collection services and the factors that encourage or discourage appropriate disposal. Such information may help waste-management agencies improve service delivery and community engagement.

Households and Community Residents

Residents may benefit from increased awareness of the relationship between waste disposal, stagnant water, mosquito breeding and disease risk. The study may encourage households to reduce indiscriminate disposal, remove water-holding waste materials and participate more actively in community sanitation.

Policy Makers

The findings may provide evidence for policymakers concerned with urban sanitation, waste management, vector control and disease prevention. The study may reinforce the need for integrated environmental health policies that recognize the interaction between waste management and vector-borne disease prevention.

Researchers and Students

The study will contribute to the literature on environmental sanitation, household waste management and mosquito-borne diseases in Nigeria. It may also serve as a reference for future researchers investigating environmental determinants of malaria and other mosquito-borne diseases in urban communities.

1.8 Scope of the Study

The study focuses on household waste disposal practices and the risk of mosquito-borne diseases among selected households in Port Harcourt City Local Government Area, Rivers State.

The content scope covers household waste storage, collection, transportation and disposal practices; methods of disposal such as authorized collection, communal disposal, open dumping, burning and disposal in drains or waterways; knowledge of mosquito breeding; environmental conditions around households; potential mosquito breeding sites; mosquito-control practices; and perceived or reported risk of mosquito-borne diseases.

Geographically, the study is limited to selected urban communities within Port Harcourt City Local Government Area of Rivers State. The study will focus on selected households rather than all households in the Local Government Area.

The study will primarily consider mosquito-borne diseases of public health relevance, particularly malaria, while recognizing that mosquitoes can also transmit other diseases such as dengue, yellow fever and chikungunya. The study does not attempt to diagnose mosquito-borne infections clinically or determine the specific mosquito species responsible for transmission. Rather, it examines household practices and environmental conditions associated with mosquito-borne disease risk.
