A literature review evaluating new approaches to resolving the sanitation challenge in developing Asia

Evidence shows that there are numerous socioeconomic and environmental benefits from improved sanitation; conversely, numerous studies have explored the lack of access to basic sanitation and its negative impact on gross domestic product (GDP). This paper establishes the positive impacts on GDP from investment in sanitation and emphasizes how it can regenerate countries. As the backdrop of this idea, this paper combines and analyzes supporting evidence through an extensive literature review to show that a new way of thinking informed by a comprehensive understanding of the historical issues faced must be adopted to address the sanitation challenge. This paper emphasizes decentralization, technological standardization, innovative financing, cost-recovery mechanisms and the potential of socioeconomic spillover effects as tools to revitalize the sanitation sector. It further elaborates on the significance of hybrid governance and institutional mechanisms, including state and non-state actors, to collectively contribute toward achieving total sanitation coverage in developing Asian countries. The paper shares the message that the benefits of wastewater management are far-reaching and conveys the importance of decision makers prioritizing this sector. The paper concludes that achieving replicability and scalability requires dedicated political will and visionary leadership.
