Land use change and indigenous knowledge systems in the Tampun Juah customary forest: Implications for resilience and cultural sustainability

The Tampun Juah Customary Forest, located in Sanggau Regency, West Kalimantan, has a rich history of natural resource management by indigenous communities. This study aims to analyze changes in land use within this customary forest, focusing on the impact of land allocation on the livelihoods of the community. The study integrates spatial analysis tools such as ArcGIS 10.3, Google Earth validation, and temporal analysis using high-resolution satellite imagery (Landsat 8 and Sentinel 2) to evaluate land cover changes. Land cover classification follows the national classification protocols established by the Indonesian Ministry of Environment and Forestry, by SNI 764.591:2014 for cartographic representation at a scale of 1:250,000. Additionally, qualitative methods, including in-depth interviews with 15 indigenous community leaders and members, participatory observation, and Focus Group Discussions (FGDs) involving 6-8 participants per group, were used to gather insights on local knowledge systems and their contributions to ecological resilience and sustainable land. The findings indicate that traditional land management practices, such as mixed cropping, have significantly declined due to the conversion of land for large-scale plantations, adversely affecting the sustainability of both ecosystems and indigenous cultures. These results underscore the importance of integrating indigenous knowledge systems into natural resource management to achieve cultural sustainability and resilience.
