Abstract

Saninten (Castanopsis argentea) and tungurut (Castanopsis tungurrut) are plant species belonging to the family Fagaceae, native to the mountainous forest ecosystem within the Gunung Halimun-Salak National Park (GHSNP). These species are currently classified as endangered according to the IUCN Red List due to their significance in providing seeds for consumption and wood for construction materials. This research aims to examine the local community’s knowledge concerning the presence, scarcity, and underlying causes of the decline of both species in the buffer villages of GHSNP. In this study, we employed survey methods and semi-structured interviews conducted with various informants. The data collected were meticulously described and analyzed descriptively. The findings revealed that the local community, in general, holds knowledge about the scarcity of species primarily based on field observations rather than legal or conservation status. Currently, both species are challenging to locate in the buffer villages of the GHSNP. According to the local community’s knowledge, the causes of species scarcity can be categorized into internal and external factors. Internal factors include both species having a slow natural regeneration pattern, difficulties in germination, and vulnerability of seedlings to environmental conditions. Meanwhile, external factors encompass seed and timber exploitation, habitat loss, climate changes, limited knowledge, skills, and understanding of forest plants, and the current perception among locals that C. argentea and C. tungurrut offer limited economic benefits, leading to the gradual neglect of these species’ existence.

Abstract

Mangrove forests are vital for maintaining coastal ecosystem balance and mitigating climate change through blue carbon storage. This study present a novel integration of blue carbon economic valuation and community-Based mangrove Management (CBMM) assessment at the village scale, using mojo village, Indonesia as a case study. Mojo village was chosen as the research location because of the carbon potential that Mojo village has to be developed using the CBMM concept. A mixed-method approach combined secondary data analysis of mangrove carbon stocks with semi-structured interviews involving key members of the Pelita Bahari community group. The Mojo Village mangrove ecosystem demonstrated substantial blue carbon value, estimated between IDR 34.66 million and IDR 199.78 million per hectare under different carbon market scenarios, indicating substantial mitigation and financial potential. CBMM analysis reveals that strong local participation and institutional legitimacy support conservation outcomes; however, limited technical capacity, external dependence, and weak monitoring constrain readiness for carbon market participation. Analytically, the findings demonstrate that carbon valuation alone is insufficient without parallel governance strengthening. Community-based mangrove management supports the sustainability of coastal ecosystems and contributes to community welfare through the economic valorization of blue carbon. Beyond local benefits, this study contributes to the global blue carbon discourse by illustrating how village-level community management can inform scalable, socially inclusive pathways for integrating mangroves into national climate strategies, carbon markets, and international mitigation frameworks under the Paris Agreement.
