Impact of Improper Waste Disposal on Environmental Quality in Aba, Abia State

CHAPTER ONE

1.0 Introduction

Waste generation is a natural part of human activity, but when waste is not properly managed, it creates serious environmental and public health problems. Urban areas in Nigeria face increasing challenges with waste collection, disposal, and recycling. The uncontrolled dumping of refuse in open spaces, drains, and water channels leads to environmental degradation, flooding, and the spread of diseases.

In Aba, Abia State, poor waste management has become a major concern for both residents and authorities. The city, known for its vibrant commercial and industrial activities, produces large volumes of solid and liquid waste daily. However, waste disposal systems are often inadequate or poorly maintained. According to Okafor and Eze (2022), a significant proportion of waste generated in Aba is dumped in open spaces or along roadways, posing risks to air, soil, and water quality. Evaluating the impact of improper waste disposal on environmental quality in Aba is therefore essential for promoting urban sustainability and public health.

1.1 Background to the Study

Improper waste disposal occurs when solid or liquid waste is discarded without considering environmental standards or safety procedures. It often results from poor planning, lack of infrastructure, and weak enforcement of waste management regulations. The World Health Organization (WHO, 2020) notes that poorly managed waste leads to pollution, vector-borne diseases, and greenhouse gas emissions.

Aba, one of the most industrialized cities in southeastern Nigeria, generates a large quantity of waste due to its manufacturing and trading activities. The city’s waste management system struggles to cope with the growing population and economic expansion. Many residents dispose of refuse in drainage channels, vacant lots, and nearby rivers such as the Aba River. As a result, the environment experiences pollution, unpleasant odors, and recurrent flooding. Iheanacho and Nwosu (2021) observed that blocked drains and open dumpsites in Aba contribute significantly to environmental degradation and the spread of diseases such as cholera and malaria.

Given these challenges, it becomes important to study how improper waste disposal affects the quality of the environment and the health of residents. Understanding this relationship will help develop effective waste management strategies for Aba and similar urban centers.

1.2 Statement of the Problem

Aba continues to face severe waste disposal challenges despite several interventions by the Abia State Environmental Protection Agency (ASEPA). Open dumping remains a common practice, and many residents lack access to organized waste collection services. Heaps of refuse often line major streets and markets, creating unsanitary conditions. During rainfall, these wastes wash into drainage systems, causing blockages and flooding.

The resulting pollution affects air quality, contaminates water sources, and reduces the aesthetic value of the city. Furthermore, exposure to decomposing waste materials poses health risks to nearby residents. Despite these problems, few studies have examined the environmental impacts of improper waste disposal in Aba. This study therefore seeks to fill that gap by assessing how poor waste management practices affect environmental quality in the city.

1.3 Aim and Objectives of the Study

The main aim of this study is to evaluate the impact of improper waste disposal on environmental quality in Aba, Abia State.

The specific objectives are to:

1. Identify the major causes of improper waste disposal in Aba.

2. Assess the effects of poor waste disposal on air, water, and soil quality.

3. Examine residents’ attitudes and awareness of waste management practices.

4. Recommend practical measures for improving waste disposal and environmental quality in Aba.

1.4 Research Questions

1. What are the major factors contributing to improper waste disposal in Aba?

2. How does poor waste disposal affect environmental quality in the city?

3. What is the level of public awareness about proper waste management?

4. Which strategies can enhance effective waste management in Aba?

1.5 Significance of the Study

This study is important because it provides empirical data on how improper waste disposal affects the environment in Aba. The results will help environmental managers, urban planners, and policymakers design better waste management systems. It will also assist health officials in developing strategies to reduce disease outbreaks associated with poor sanitation.

In addition, this research contributes to achieving Sustainable Development Goal (SDG) 11, which focuses on creating sustainable cities and communities, and SDG 13, which emphasizes climate action. It will also raise awareness among residents and promote behavioral changes that encourage recycling, waste segregation, and community participation in waste management.

1.6 Scope of the Study

The study focuses on selected areas within Aba metropolis, including Ariaria Market, Ngwa Road, Aba North, and Aba South. It covers issues related to waste generation, disposal methods, and environmental impacts such as air and water pollution. The study excludes hazardous and industrial waste treatment processes due to limited access to data and equipment.

1.7 Definition of Key Terms

• Waste: Any material that is discarded after primary use or is worthless in its current form.

• Improper Waste Disposal: The act of discarding waste in a manner that harms the environment or violates safety standards.

• Environmental Quality: The condition of the environment as measured by factors such as air, water, and soil cleanliness.

• Pollution: The introduction of harmful substances into the environment, causing adverse effects on humans and nature.

• Solid Waste Management: The process of collecting, treating, and disposing of solid materials in an environmentally friendly way.
