<![CDATA[The Danau Sentarum landscape in West Kalimantan, Indonesia, is a catchment area containing important peat wetland ecosystems that support biodiversity conservation, local livelihoods, and hydrological functions in the upper Kapuas River Basin. However, under Law No. 23/2014 on Regional Government, formal authority over watershed management in the forestry sector lies with the central and provincial governments, whereas regency governments retain responsibility for other sectoral functions that affect watershed conditions. This study examined the structural relationships among district government functions relevant to sustainablelandscape management in Danau Sentarum. Data were collected through a literature review, focus group discussions, and expert interviews with relevant institutional representatives and analyzed using Interpretive Structural Modelling. The analysis identified 30 functional elements and produced an inconsistency index of 9.56%. Environmental management, spatial planning, and land administration were positioned as the main driver functions with high driving power and low dependence. Agriculture, fisheries, tourism, trade, industry, labor, and energy and mineral resources formed linkage functions that connected ecological governance with naturebased production and local economic activities. Settlement, connectivity, investment, cooperatives and small and medium enterprises, social protection, community empowerment, and public order functions were positioned as more dependent outcomes. These results suggest that district-level watershed governance in the Danau Sentarum landscape may be improved byemphasizing environmental management, spatial planning, and land administration above the coordination of productive and welfare sectors. This study presents a function-based institutional map for district-level planning in Danau Sentarum, and requires additional validation to evaluate its use in other watershed environments.]]>
