The increasing complexity of global crises and escalating resource vulnerabilities demand cross-sectoral policy integration. The Food-Energy-Water (FEW) Nexus approach has been adopted in Indonesia as a strategic agenda within the National Medium-Term Development Plan 2025-2029 to achieve self-sufficiency targets. Responding to the challenge of institutional fragmentation during its implementation, this study aims to examine the landscape of collaborative governance within FEW Nexus-based development planning by mapping thematic trends, network patterns, and discussions from previous literature. This study applies a systematic literature review to 68 reputable journal articles from the Scopus database, published between 2016 and 2025, with data extracted and visualized using bibliometric analysis. The findings reveal that while research on nexus integration and governance is continuously growing, a disconnect persists between governance approaches and technical modeling—both quantitative and qualitative—within decision support systems. Furthermore, there is a notable gap in the literature specifically addressing national-scale collaborative action planning in Indonesia. Empirically, the study also finds that the implementation of the nexus approach is frequently hindered by sector mismatches, data asymmetry, and public sector dominance. Therefore, dismantling sectoral egos through inclusive and participatory planning, alongside strengthening the data-sharing ecosystem, are absolute prerequisites for building cross-level policy coherence to address the complexities of the FEW nexus.
