この研究は、ガーナのサバンナ生態圏における炭素貯蔵量の時間的・空間的動態を、フィールド測定、リモートセンシング、統計分析を統合した地理空間アプローチで調査した。結果は、地上部バイオマス（AGB）が2015年から2019年にかけて微増したことを示した。フィールド測定値は衛星やモデル推定値よりも高く、特に北部で過小評価が顕著であった。この研究は、サバンナ生態系における炭素貯蔵量推定の精度向上に貢献し、持続可能な土地管理と気候変動緩和戦略に示唆を与える。
English
This study examines temporal and spatial dynamics of carbon stocks in Ghana's Savannah Ecological Zone using field measurements, remote sensing, and modeling. Results show a marginal increase in aboveground biomass from 2015 to 2019. Field measurements were higher than satellite and model estimates, with greatest underestimation in the northern savannah. The work improves carbon stock estimation accuracy and informs sustainable land management and climate mitigation strategies.

📄 Abstract（原文）
Climate change remains one of the most pressing global challenges, driven primarily by increasing concentrations of greenhouse gases in the atmosphere. Terrestrial ecosystems play a crucial role in mitigating climate change by capturing and storing atmospheric carbon through photosynthesis. Despite their ecological importance, savannah ecosystems remain relatively underrepresented in global carbon studies, particularly in developing regions. This study examines the temporal and spatial dynamics of carbon stocks within the Savannah Ecological Zone of Ghana using a geospatial approach that integrates field-based measurements, remote sensing data, and statistical analysis. The results indicate that Aboveground Biomass (AGB) showed a marginal increase across the three years under review. The field measurements showed that the AGB ranged between 2.5 to 8.5 Mg C haֿ¹ within the north, central and southern parts of the savannah from 2015 to 2019. Meanwhile the satellite and model estimates ranged from 0.3 to 3.6 Mg C haֿ¹ and 0.5 to 2.5 Mg C haֿ¹ Mg C haֿ¹ respectively within the same divisions in the same years. Spatially, AGB was consistently higher in the southern savannah compared to the northern region. Both satellite-derived and model AGB estimates were generally lower than field-based measurements, with the greatest underestimation observed in the northern savannah. These findings highlight the importance of integrating field data with remote sensing techniques as well as scientific models to improve the accuracy of carbon stock estimation in savannah ecosystems. The study contributes to reducing uncertainties in carbon stock assessments and provides valuable insights for sustainable land management and climate change mitigation strategies in Ghana.
