Abstract

Tembawang agroforestry represents a traditional forest management system practiced by Dayak communities in Kalimantan and is recognized for its ecological and livelihood functions. This study examines land cover changes and carbon stock distribution in Tembawang agroforestry in Cipta Karya Village, West Kalimantan. The research applied a combination of field surveys and remote sensing using Sentinel satellite imagery from 2019 and 2023. Vegetation data were collected through observation plots to assess species composition, density, and biomass for carbon estimation using allometric equations. A total of 17 tree species were identified across Tembawang and rubber forest areas. Four species showed the highest density values: Durio zibethinus, Hevea brasiliensis, Elateriospermum tapos, and Ochanostachys sumatrana, with densities ranging from 25 to 268.75 ind ha^-1 and an overall mean of 260.42 ± 110.00 ind ha^-1. Estimated aboveground carbon stocks varied widely between 5.13 and 632.11 Mg C ha^-1, with an average of 269.71 ± 181.79 Mg C ha^-1. Land cover analysis indicated no significant change in secondary dryland forest over the past five years. However, mixed dryland agricultural areas, including parts of Tembawang, gardens, and cultivated fields, decreased by approximately 100 ha. The spatial distribution of carbon stocks across secondary dryland forest and mixed agricultural land ranged from 0 to 453.96 Mg C ha^-1, reflecting substantial variability in carbon storage across the landscape. These findings highlight the role of Tembawang agroforestry in maintaining carbon stocks while undergoing moderate land use changes.
