本論文は、ニュージーランドのブルーカーボン生態系（マングローブ、塩性湿地、海草藻場）が提供する生態系サービスの金銭的価値を推定した。炭素隔離に加え、廃水処理や文化的サービスなども含めた単位面積あたりの価値を提示し、全国的な合計価値は年間数億NZドルに及ぶことを示した。ベネフィット移転手法を用いており、投資判断や気候変動適応策の議論に資する。
English
This paper estimates the monetary value of ecosystem services from blue carbon ecosystems (mangroves, saltmarshes, seagrasses) in New Zealand. It finds that carbon sequestration is most valuable for mangroves, while waste treatment and existence values dominate for saltmarshes and seagrasses, respectively. National potential values range from NZD 0.2–995 million per year. The benefit transfer approach provides indicative benchmarks for investment and adaptation decisions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でもブルーカーボン生態系（藻場・干潟等）への関心が高まっており、本論文の評価手法は日本の沿岸生態系の価値算定にも応用可能。特に、日本の統合報告書やTCFD開示で自然資本評価が求められる中、参考事例となる。
In the global GX context
This study contributes to the global blue carbon literature by providing comprehensive monetary valuations for temperate coastal ecosystems. Its benefit transfer approach can be adapted to other regions, and the results support nature-based solutions under the Paris Agreement and emerging biodiversity disclosure frameworks like TNFD.

📄 Abstract（原文）
Blue carbon ecosystems (BCE), including mangroves, saltmarshes, and seagrasses, provide essential functions and services globally but are increasingly challenged by climate change and other anthropogenic activities. In Aotearoa New Zealand (Aotearoa NZ), there is mounting interest in blue carbon as a nature‐based solution to climate change. Quantifying the monetary co‐benefits of BCE, in addition to carbon sequestration, can help illustrate the relative contribution of ecosystem services provided by existing habitats, as well as the potential additional value associated with restoration. Here, we estimated the value of provisioning, regulating, and cultural ecosystem services provided by BCE in Aotearoa NZ. We found that the most valuable ecosystem service provided by mangroves was carbon sequestration, while in saltmarsh and seagrass, the most valuable ecosystem services were waste treatment and existence, bequest values, respectively. Unit monetary valuations of ecosystem services range from NZD 3 ha −1 yr −1 (water flow regulation) to NZD 32,590 ha −1 yr −1 (climate regulation) for mangroves, NZD 8 ha −1 yr −1 (spiritual experience) to NZD 23,045 ha −1 yr −1 (waste treatment) for saltmarshes, and NZD 3 ha −1 yr −1 (water regulation) to NZD 14,512 ha −1 yr −1 (existence, bequest values) for seagrasses. The estimated national potential monetary value of ecosystem services provided by current habitats ranges from NZD 0.8–995 million yr −1 for mangroves (30,533 ha nationally), NZD 0.2–482 million yr −1 for saltmarshes (20,932 ha nationally), and NZD 0.2–216 million yr −1 for seagrasses (61,340 ha nationally). If drained areas were restored from drained agricultural use, values would increase accordingly. These results apply the benefit transfer approach (applying monetary values from analogous temperate ecosystems globally to estimate values in Aotearoa NZ) to generate indicative monetary benchmarks, which can help inform discussions around investment in BCE and long‐term coastal climate change adaptation decision‐making in Aotearoa NZ.
