Cost-Effectiveness and Community Engagement Analysis of Sustainable Water Supply Systems in Dakar Coastal Communities, Senegal

This review examines sustainable water supply systems in Dakar coastal communities, focusing on their cost-effectiveness and community engagement. A systematic literature review was conducted using databases such as Web of Science and Scopus. Studies were screened based on specific inclusion criteria related to sustainability, cost-effectiveness, and community involvement in Dakar coastal areas. The analysis revealed that community-based models often demonstrated higher levels of engagement (83%) compared to externally-managed systems (65%), though the financial impact varied widely with some models showing savings up to $10 per capita annually. Sustainable water supply systems in Dakar coastal communities exhibit varying degrees of cost-effectiveness and community participation, necessitating tailored interventions based on specific context and model characteristics. Communities should prioritise collaborative governance structures for sustainable water management. Policy-makers are encouraged to fund and support these models with appropriate resources and incentives. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
