Rapid urbanization has accelerated the degradation of subak rice fields in Bali, as evidenced by pollution of irrigation channels and reduced agricultural productivity. This study assessed the extent and characteristics of land degradation in South Denpasar and formulated sustainable management strategies for restoring the ecological and cultural integrity of the subak system. The Logical Framework Approach (LFA) was applied to identify key problems, analyze causal relationships, and develop measurable strategies. Data were obtained through questionnaires, interviews, field observations, and document analysis. The results showed that approximately 87 hectares of subak land were lost within five years, driven by weak spatial enforcement, domestic and industrial waste pollution, and limited farmer regeneration. This study formulated five priority strategies: (1) enforcement of land use regulations, (2) economic incentives for conservation farming, (3) integration of Tri Hita Karana values, (4) farmer capacity building through digital technology, and (5) improved irrigation maintenance. This research highlights that sustaining the subak system requires a multi-dimensional management approach that integrates ecological restoration, socio-economic empowerment, and cultural revitalization. Adoption of this framework by local authorities can enhance urban land governance, strengthen farmer livelihoods, and preserve Bali’s cultural agricultural heritage amid ongoing urban pressures.
