Panel data analysis reveals moderate improvements in municipal water systems efficiency in Nigeria, suggesting policy enhancements are needed.
The inefficiency of municipal water systems in Nigeria has led to significant health and environmental challenges. This review employs systematic literature search methods to identify relevant studies. A mixed-method approach is adopted, combining quantitative and qualitative insights for comprehensive evaluation. Panel-data estimation reveals a moderate improvement in system efficiency over the last decade (proportion of systems improving by about 20%). The review underscores the need for improved policy frameworks and investment in technological upgrades to enhance water system performance. Policy-makers should prioritise stakeholder engagement, robust data collection, and continuous monitoring of municipal water systems efficiency. The empirical specification follows Y=β₀+β^ X+ε, and inference is reported with uncertainty-aware statistical criteria.
