1.1 Introduction
Waste management refers to the systematic process of collecting, transporting, treating, recycling, and disposing of waste materials in a manner that protects public health and preserves the environment (United Nations Environment Programme [UNEP], 2021). It is an essential environmental management practice that promotes cleanliness, reduces pollution, and supports sustainable development. In contrast, poor waste management practices often result in environmental degradation, health challenges, and economic losses.
Waste disposal is one of the major components of waste management because it involves the final treatment or placement of waste in approved locations or through environmentally friendly methods such as recycling, composting, sanitary landfilling, and incineration. Rapid population growth, urbanization, and increased consumption according to World Bank (2022) have significantly increased the volume of solid waste generated in developing countries, including Nigeria. However, the capacity of waste management systems has not grown at the same pace, leading to indiscriminate dumping, overflowing refuse sites, blocked drainage channels, and widespread environmental pollution.
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
Waste management has become one of the most important environmental issues facing both developed and developing countries because of the increasing volume of waste generated from human activities. According to the United Nations Environment Programme, waste management involves the systematic collection, transportation, treatment, recycling, recovery, and final disposal of waste in ways that protect human health and the environment (UNEP, 2021). As population growth, urbanization, industrialization, and changing consumption patterns continue to increase, the amount of solid waste generated also rises. According to World Bank, the rapid increase in municipal solid waste has become a significant challenge for many developing nations because existing waste management systems often fail to keep pace with growing demand (World Bank, 2022). Effective waste management therefore remains an essential component of sustainable environmental development, public health protection, and economic progress.
According to World Health Organization, improper waste disposal exposes communities to environmental pollution and several preventable diseases by contaminating land, air, and water resources (WHO, 2021). Similarly, Kaza et al. (2018) reported that poor waste management practices contribute to greenhouse gas emissions, environmental degradation, flooding, and increasing health hazards in many developing countries. Waste generated from households, markets, schools, industries, hospitals, and commercial establishments requires proper handling to prevent environmental contamination. When wastes are not properly collected and disposed of, they accumulate in unauthorized locations, block drainage systems, and create breeding grounds for mosquitoes, rodents, and other disease vectors. Consequently, effective waste management has become an essential strategy for improving environmental sanitation and promoting healthy living.
Waste management practices according to Afon (2012) include waste reduction, waste segregation, reuse, recycling, composting, regular collection, transportation, treatment, and environmentally safe disposal methods. These practices encourage the proper handling of waste from the point of generation to its final disposal. In the same vein, Ogwueleka (2009) asserted that sustainable waste management depends on the active participation of households, government agencies, private waste contractors, and community members. The effectiveness of waste management practices therefore depends not only on the availability of facilities but also on public awareness, environmental education, and compliance with established environmental regulations. Communities that adopt proper waste management practices generally experience cleaner surroundings, improved public health, and reduced environmental pollution.
Waste disposal represents the final stage of waste management and determines the extent to which environmental quality is maintained. According to Hoornweg and Bhada-Tata (2012), environmentally sound disposal methods such as sanitary landfilling, composting, recycling, and controlled incineration reduce environmental pollution and improve resource conservation. In contrast, indiscriminate dumping, open burning, and disposal of refuse into drainage channels or water bodies increase environmental degradation and expose communities to avoidable health risks. The quality of waste disposal therefore depends largely on the effectiveness of waste management practices adopted within a community.
Nigeria has continued to experience enormous challenges in managing municipal solid waste despite several environmental policies and intervention programmes. According to the Federal Ministry of Environment (2020), rapid urbanization, increasing population, inadequate waste collection facilities, weak institutional capacity, and poor enforcement of environmental regulations have contributed significantly to ineffective waste management across the country. Likewise, Nzeadibe and Ajaero (2010) contended that indiscriminate waste disposal remains common in many Nigerian communities because of inadequate waste infrastructure, irregular collection services, and limited public participation in environmental sanitation programmes.
This study is therefore expected to contribute to existing knowledge on environmental management while providing useful recommendations for improving waste disposal in Cuda. This study is set against the backdrop of increasing concerns over ineffective waste management practices and their influence on waste disposal in Nigeria.
1.3 Statement of Problems
Investigation revealed that improper waste disposal has become a major environmental challenge in many Nigerian communities, including Cuda, due to poor waste management practices. Refuse is often dumped along roadsides, in open spaces, drainage channels, and other unauthorized locations, resulting in blocked drains, environmental pollution, offensive odours, and increased health risks. On the other hand, many residents still have limited awareness of proper waste management practices, making the problem more widespread.
Furthermore, although government agencies and environmental authorities have introduced sanitation programmes and waste management policies, the level of compliance and community participation remains inadequate in many areas. This situation has made it difficult to achieve sustainable waste disposal and environmental cleanliness. It is against this backdrop that this study seeks to examine the effect of waste management practices on waste disposal in Nigeria, using Cuda as a case study.
1.4 Aim and Objectives of Study
