Abstract

As the global demand for sustainable water management solutions continues to escalate, the prioritization of Nature-Based Solutions (NBS) has emerged as a critical strategy for addressing water challenges. This study presents a comprehensive approach to prioritize NBS using Multiple Criteria Decision Analysis (MCDA) within the context of a water utility case study in São Paulo, Brazil. São Paulo, a megacity grappling with water scarcity and quality issues, serves as an ideal setting to explore the effectiveness of NBS in mitigating water-related challenges. Through an integrated MCDA framework, various criteria such as environmental impact, total cost, integration with existing infrastructures, flexibility, simplicity and transparency, supply safety, among others are evaluated to assess the suitability of NBS alternatives. The study employs a participatory approach involving stakeholders from diverse sectors to ensure transparency and inclusivity in the decision-making process. By synthesizing qualitative and quantitative data, the MCDA facilitates the identification of optimal NBS interventions tailored to the unique socio-environmental context of São Paulo. The findings of this study not only contribute to advancing knowledge on NBS prioritization methodologies but also offer practical insights for water utilities and policymakers seeking sustainable solutions to water management challenges in urban settings.
