Spatial modelling of mangrove AGC stock using vegetation indices and LULC changes in coastal area of Teluknaga and Kosambi, Indonesia Ramzan Pradana Maulsyid, Willdan Aprizal Arifin, Yulius, Taslim Arifin, Anang Dwi Purwanto, et al. Anthropocene Coasts, 2026 Mangrove ecosystem along the coast of Indonesia has experienced degradation and loss of carbon stocks due to extensive coastal development and land conversion. This study aims to develop a spatial model for estimating Above-Ground Carbon (AGC) stocks in the mangrove forests of Teluknaga and Kosambi in 2019, 2022, and 2025. Using Sentinel-2 satellite imagery, Land Use and Land Cover (LULC) was classified using the Random Forest (RF) algorithm, resulting in five main classes including water bodies, mangrove, vegetation, bareland, and built-up area. Vegetation indices (NDVI, EVI, SAVI, and ARVI) were specifically calculated for mangrove areas to construct a linear regression model against the reference AGB values obtained from secondary data. Results indicate that ARVI is the best predictor (R 2 = 0.80; RMSE = 40.98). The maximum AGC value recorded was 177.47 MgC ha −1 in 2019, decreasing to 153.36 MgC ha −1 in 2022 and plummeting to 111.62 MgC ha −1 in 2025. This decline is also reflected in the total carbon stock in the study area, which fell from 987,973.4 MgC to 595,583.8 MgC. This is related to the reduction in mangrove area from 368.45 ha in 2019 to 261.16 ha in 2025. Spatially, the conversion of mangrove to bareland and built-up area reached a total of 122.72 ha, with a predominance of conversion to bareland (78.66 ha) and to built-up area (44.06 ha). This study presents novelty through the utilisation of LULC changes as a spatial approach in estimating carbon reserves and provides a scientific basis for the protection of mangrove ecosystems amidst coastal development pressures.
The spatio-temporal analysis of land use changes & above-ground carbon stock in Sumbawa mangrove ecosystem, Indonesia Jaka Putra Rahmajati, Vina Nurul Husna, Yulius Yulius, Taslim Arifin, Hadiwijaya L. Salim, et al. Anthropocene Coasts, 2026 Mangrove deforestation in Indonesia amounts to roughly 18,209 ha per year (18.26 MtCO₂e/year −1 ). However, spatial and temporal integrative research in eastern Indonesia's coastal areas remains limited. This study aims to analyse mangrove forests' condition and spatio-temporal changes, compute above-ground carbon (AGC) as a basis for sustainable coastal management in Sumbawa Regency and support the 2030 Nationally Determined Contribution (NDC) target. This research merges UAV-RGB data (July 2024) and multitemporal PlanetScope imagery (2016 and 2024) to develop a Canopy Height Model (CHM) and calculate the AGC. Land use classification was accomplished using Object-Based Image Analysis (OBIA)—Random Forest (RF), while changing trends were assessed using Modules for Land Use Change Evaluation/Simulations (MOLUSCE). AGC at the study site was in the range of 21—168 $${\\text{MgC}.\\text{ha}}^{-1}$$ MgC . ha - 1 (mean = 72.3 $${\\text{MgC}.\\text{ha}}^{-1}$$ MgC . ha - 1 , total = 8,999.9 $$\\text{MgC}$$ MgC . The investigation found a change of 37.89 ha of mangrove area to barren and shrubland, resulting in an AGC loss of 2,739.5 $$\\text{MgC}$$ MgC . However, there has been an increase in land use and changes in aquaculture and agriculture. This study proposes a novel approach by merging UAV data and time-series satellite images to increase the accuracy of AGC prediction in data-sparse locations. A nature-based Solution (NbS) is advocated as an integrated method for adaptive mangrove restoration and conservation, while still supporting the demands of the local community. This research presents a geographical framework that may be duplicated to create inclusive and adaptable coastal resource management plans and directly contribute to reaching the 2030 NDC targets.
