塩性湿地はブルーカーボンの長期貯蔵に重要だが、過去の排水や土地利用転換でCO2を排出してきた。本研究はGoogle Earth Engineを用いて衛星データから塩性湿地の植生被覆変化を年単位で監視するモデルを開発。NDVI分類の初期精度は62%だが、植生対裸地の二値分類では90%超の精度を示し、GHGインベントリ報告への応用可能性を示した。
English
Saltmarshes are vital for blue carbon storage but have historically emitted CO2 due to drainage and land-use change. This study uses Google Earth Engine to develop a satellite-based model for annual monitoring of saltmarsh vegetation cover after restoration across five UK sites. The NDVI classification achieved 62% accuracy initially, but simplified to vegetated vs. bare soil (relevant for GHG inventory reporting) it exceeded 90%, offering a scalable method for tracking carbon removals in national inventories.

日本のGX文脈において
日本ではブルーカーボン生態系の評価手法が注目されており、本論文の衛星リモートセンシングによるモニタリング手法は、日本の干潟・藻場・塩性湿地の炭素吸収量算定にも応用可能。ただし、英国の事例であり、日本の生態系特性や潮汐条件に合わせた調整が必要。
In the global GX context
This paper demonstrates a practical remote sensing method for monitoring saltmarsh restoration, directly relevant to national GHG inventory reporting under the Paris Agreement. It supports the growing global interest in nature-based solutions and blue carbon accounting, offering a scalable approach that could be adapted for other coastal ecosystems and countries.

📄 Abstract（原文）
Saltmarsh habitats are recognised for their role in long-term sequestration and storage of ‘blue carbon’. Historically, saltmarshes have been subject to high levels of drainage and land-use change, resulting in past CO2 emissions. However, reversing these management practices through rewetting and revegetation of saltmarsh at coastal realignment sites presents opportunities to sequester carbon as part of a nature-based mitigation against climate change. We used Google Earth Engine to develop a model based on satellite data that can monitor annual saltmarsh vegetation cover changes following restoration across five UK test sites. Classification of saltmarsh communities was ultimately based on monthly 75th centile Normalized Difference Vegetation Index (NDVI) values, which represents “greenness” of the land surface, to minimise the effect of tidal phases. Model results demonstrate a useful method for historic and continued monitoring of saltmarsh habitat condition, with initial accuracy of 62% for the NDVI classification. However, when classification was simplified into vegetated versus bare soils (i.e. the criteria for inclusion into national GHG inventory reporting) accuracy of over 90% was reported. This method provides a living picture of colonised saltmarsh that could be upscaled for tracking the carbon removals associated with saltmarsh restoration and management in GHG inventories.
