Abstract
Water scarcity is intensifying globally, increasing the need for sustainable and locally adaptable water solutions. Rainwater harvesting systems (RHS) are promoted as a practical response, yet poor site selection often limits success. This study integrates the Sustainable Livelihood Framework (SLF) into the RHS site selection to assess how social, economic, and technical factors interact. A hybrid multi-criteria decision-making approach was applied, combining the Fuzzy Delphi Method to validate determinants, the Fuzzy Analytic Hierarchy Process to prioritize them, and Fuzzy DEMATEL to map interdependencies. Out of 43 initial determinants, 26 were validated. Results indicate that socio-economic livelihood capitals are the most influential, while natural factors like rainfall remain indispensable enabling conditions. Key determinants include rainfall, leadership support, community participation, water equity, and subsidies, whereas education, credit access, technical skills, energy supply, and maintenance costs drive implementation. The study offers a holistic framework for inclusive, resilient, and context-responsive water resource planning.
