中国の潮汐湿地を対象に、メタ分析で埋立による炭素損失と再生による炭素獲得を定量化した研究。過去30年でマングローブは回復し2052年までに1973年水準へ戻る一方、塩性湿地の損失は鈍化し2070年に1984年水準回復と予測。炭素蓄積の消失が最大の損失経路で、再生後はバイオマス回復が主要な獲得源。マングローブ6.8Tg、塩性湿地55.2Tgの炭素獲得可能性を示す。
English
A meta-analysis quantifying decadal blue carbon losses from tidal wetland reclamation and gains from restoration in China. Carbon stock depletion was the largest loss pathway (49.18% mangroves, 37.33% tidal marsh), while biomass recovery drove gains after restoration. Projections suggest restoring mangroves to 1973 extent yields 6.8 Tg carbon, and tidal marsh to 1984 coverage yields 55.2 Tg, offering a scientific basis for blue carbon accounting.

📝 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はJ-クレジット制度や港湾・沿岸域の脱炭素施策で注目されるが、本論文は中国の事例であり直接の政策連動は限定的。ただし湿地再生の炭素会計手法は、日本の沿岸域ブルーカーボン評価や生物多様性クレジット議論に方法論的示唆を与える。
In the global GX context
Blue carbon is increasingly integrated into global climate disclosure and nature-related frameworks (TNFD, SBTN), though this paper is a scientific accounting study rather than a disclosure analysis. It contributes empirical evidence on restoration pathways that could inform carbon credit methodologies and national inventory reporting under the Paris Agreement.

📄 Abstract（原文）
Abstract Tidal wetlands are blue carbon ecosystems, and the restoration of these ecosystems is a natural climate solution due to their remarkable carbon sequestration capacity. However, extensive conversion to aquaculture ponds in China has led to substantial carbon losses. Recent restoration initiatives aim to change the situation. To quantify these impacts, we performed a meta-analysis to assess carbon losses and gains from different pathways, including sediment and biomass carbon storage, carbon burial, carbon emissions, and carbon content changes. We aim to estimate the decadal carbon losses from reclamation and gains from restoration in China’s tidal wetlands. Over the past 30 years, mangrove areas have gradually recovered and are projected to return to 1973 levels by 2052, while tidal marsh loss has slowed, with restoration expected to achieve 1984 levels by 2070. Carbon stock depletion represented the largest loss pathway, accounting for 49.18% of mangrove and 37.33% of tidal marsh losses. Following restoration, biomass recovery contributed significantly to carbon gains: 28.5% for mangroves and 44.4% for tidal marshes. Projections indicate that restoring mangroves to their 1973 extent would yield a carbon gain of 6.8 Tg, while tidal marsh restoration to 1984 coverage would generate 55.2 Tg. These pathways provide a scientific basis for global blue carbon accounting and management strategies.
