1.1 Introduction
Waste management is the systematic collection, transportation, treatment, recycling, and disposal of waste materials to reduce their negative impact on human health and the environment (United Nations Environment Programme [UNEP], 2021). It is an essential component of urban sustainability, particularly in developing countries where rapid urbanization and population growth have intensified environmental challenges. Effective waste management involves not only physical handling but also the use of strategic planning and technology to ensure that waste is efficiently managed from generation to final disposal. In the context of modern governance, data-driven strategies are increasingly recognized as vital tools for achieving sustainable and efficient waste management systems (Adebayo & Olanrewaju, 2022).
Data-driven strategies in waste management refer to the application of data analytics, artificial intelligence (AI), and other digital tools to collect, process, and analyze waste-related information for better decision-making (Eze & Nwachukwu, 2023). 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 pressing challenges facing urban centers in developing nations, particularly in Nigeria, where rapid urbanization, industrial growth, and population expansion have intensified waste generation. According to Akinyemi (2021), the rate at which waste is generated in Nigerian cities far exceeds the capacity of existing management systems, leading to environmental degradation, blocked drainage systems, and increased health risks. The United Nations Environment Programme (2021) reported that improper waste management contributes significantly to urban pollution and greenhouse gas emissions, particularly in developing economies that lack modern disposal and recycling infrastructures.
Olawale (2020) asserted that traditional waste management systems in Nigeria are largely reactive, relying on outdated methods of waste collection and disposal without adequate integration of technology and data analytics. This inefficiency has led to inconsistent waste collection schedules, unplanned landfill usage, and minimal recycling activities. Similarly, Eze and Nwachukwu (2023) stated that the absence of reliable data has made it difficult for policymakers to make informed decisions, predict waste generation patterns, and evaluate the effectiveness of waste management interventions. As a result, most Nigerian cities continue to struggle with uncollected waste and poor environmental hygiene.
In Lagos, the largest and most populous urban center in Nigeria, waste management poses an even greater challenge due to the city's high population density and economic activities. Okafor and Eze (2023) contended that Lagos produces over 13,000 tonnes of solid waste daily, a figure that continues to rise with urban expansion. Despite efforts by the Lagos Waste Management Authority (LAWMA) to improve collection and disposal processes, many areas still experience irregular waste evacuation and illegal dumping. Adebayo and Olanrewaju (2022) affirmed that a lack of data-driven planning has made it difficult for LAWMA to optimize collection routes, allocate resources efficiently, or implement effective recycling programs.
Furthermore, Ogunyemi and Adebayo (2022) reported that the application of data analytics, artificial intelligence, and Geographic Information Systems (GIS) in waste management offers a significant opportunity for improving operational efficiency and environmental sustainability. These technologies enable real-time monitoring of waste generation, predictive modeling for collection routes, and performance evaluation of waste service providers. According to Nwachukwu (2022), adopting data-driven systems allows urban authorities to shift from reactive waste management approaches to proactive, evidence-based decision-making.
Adebayo and Olanrewaju (2022) asserted that inadequate funding, insufficient technical expertise, and institutional resistance have slowed the transition toward data-driven waste management systems. On the other hand, the growing digital transformation across sectors presents an opportunity for integrating big data and smart technologies into waste management operations. As Eze and Nwachukwu (2023) affirmed, embracing data-driven strategies will not only enhance efficiency and transparency but also promote environmental sustainability in Nigerian urban centers. This study is set against the backdrop of assessing how data-driven strategies can be effectively utilized to improve waste management systems in Nigerian cities.
1.3 Statement of Problems
Investigation revealed that the Lagos Waste Management Authority (LAWMA) is mandated to manage solid waste within the metropolis; however, its operations are often hindered by limited data utilization for planning, monitoring, and evaluation. Most waste collection activities rely on manual estimations rather than predictive analytics or geographic information systems (GIS) that could optimize collection routes and resource allocation (Ogunyemi & Adebayo, 2022).
On the other hand, the increasing availability of digital technologies and analytical tools provides an opportunity to transform waste management operations into a more sustainable and efficient system. The integration of data analytics, machine learning, and IoT technologies is therefore essential in enhancing decision-making, predicting waste generation trends, and promoting environmental sustainability (Eze et al., 2023).
Furthermore, the lack of real-time data sharing between stakeholders such as waste collectors, recycling firms, and regulatory agencies creates communication gaps that limit the effectiveness of urban waste management policies. It is against this backdrop that this study seeks to assess the role of data-driven strategies in improving waste management efficiency in Nigerian urban centers.
1.4 Aim and Objectives of Study
The aim of this study is to assess the impact of data-driven strategies on improving waste management efficiency and sustainability in Nigerian urban centers, using the Lagos Waste Management Authority as a case study. To achieve this aim, the study has the following objectives:
- To examine the current waste management system in Lagos and identify operational inefficiencies.
- To investigate the role of data-driven strategies in enhancing waste collection and disposal.
