Abstract

A landscape carrying capacity assessment serves as a critical tool for strengthening sustainable natural resource governance within socio-ecological systems. This study aimed to evaluate the carrying capacity status of the Sentarum Lake Catchment Area and identify key ecological and socioeconomic vulnerabilities. The analysis was conducted using a multi-criteria index-based approach aligned with the Indonesian Minister of Forestry Regulation No. P.61/Menhut-II/2014, integrating cross-sectoral data across five dimensions: land condition, water regime, socioeconomic conditions, water infrastructure, and land use patterns. The results showed that the carrying capacity was classified as “good,” with an index value of 78.00. Nevertheless, a phenomenon of pseudo-hydrological stability was identified, in which stable flow regimes (flow regime coefficient = 0.50) and high water availability (water use index = 0.50) masked functional degradation within the system. This condition was reflected in a high annual runoff coefficient (1.50) and increasing flood frequency (1.25), indicating declining infiltration capacity. These pressures were further exacerbated by the limited proportion of natural vegetation within protected areas (45.10%) and high socioeconomic vulnerability (poverty level index = 1.50). Overall, the findings indicate a fragile equilibrium in which apparent ecological stability conceals emerging hydrological and socioeconomic risks. Without adaptive and integrated management interventions, the system is likely to shift toward structural degradation. Therefore, strengthening landscape governance requires ecosystem-based spatial planning, nature-based mitigation strategies, and inclusive local economic development to enhance long-term resilience.

Abstract

Bukit Duabelas National Park is a protected area that functions as both a biodiversity conservation area and a living space for the Orang Rimba community. While previous studies have mainly documented Orang Rimba ethnobiological knowledge, this study quantitatively links biological resource availability, utilization intensity, and sustainability prospects within an indigenous livelihood system. Field observations, vegetation sampling, line transects, and semi-structured interviews were conducted with 88 respondents from 13 tumenggung groups. The data were analyzed using quantitative and qualitative descriptive analysis, and sustainability assessments based on plant regeneration structure and wildlife harvest-to-production ratios. The results showed that the Orang Rimba utilized 74 plant species from 45 families and eight wildlife species for food, medicine, construction, trade, clothing, and cultural purposes. Plant use was dominated by food and medicinal resources, with average harvesting intensities of 245.34 and 203.75 events per year, respectively. A sustainability assessment classified 14.86% of plant species as sustainable, 40.54% as moderately sustainable, and 44.59% as unsustainable. Wildlife use was generally unsustainable because maximum harvest estimates exceeded conservative annual production and upper reproductive estimates for most species. These results stress the need for adaptive and participatory management strategies that prioritize both biodiversity preservation and sustainable Orang Rimba livelihoods.
