本研究は、インドネシア・カリマンタンのテンバワン・アグロフォレストリーにおける土地被覆変化と炭素貯蔵量を評価した。センチネル衛星画像と現地調査に基づき、2019年から2023年の間で二次乾燥林には大きな変化がないが、混交乾燥農業地域が約100ha減少したことを明らかにした。地上部炭素貯蔵量は平均269.71 Mg C/haと推定され、場所による変動が大きい。テンバワン・アグロフォレストリーが炭素貯蔵維持に貢献していることを示している。

This study assesses land cover change and carbon stocks in Tembawang agroforestry in West Kalimantan, Indonesia, using Sentinel imagery and field surveys. Secondary dryland forest remained stable from 2019 to 2023, while mixed dryland agricultural areas decreased by about 100 ha. Aboveground carbon stocks averaged 269.71 Mg C/ha with high spatial variability. The findings highlight the role of traditional agroforestry in maintaining carbon storage under moderate land use changes.

In the global GX context
This paper provides empirical carbon stock estimates for a traditional agroforestry system, relevant to global nature-based solution frameworks and REDD+ projects. It demonstrates the use of remote sensing and field plots for carbon accounting in tropical landscapes, which can inform Land Use, Land-Use Change and Forestry (LULUCF) reporting under the Paris Agreement.

📄 Abstract（原文）
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.
