本研究は、497種の商業漁獲種に関する約1,600のリスク予測を系統的レビューと線形混合モデルで分析し、気候緩和策が漁業の持続可能性に与える影響を評価した。緩和策がない場合、92%の予測で極方向への分布移動が見られ、平均で10年あたり50kmの移動が予測される。パリ協定に沿った緩和策により、分布移動を3分の2削減し、絶滅リスクを5倍低減できると示された。南米や東南アジアなど漁業依存度の高い地域でのデータ不足も指摘されている。

This study analyzed ~1,600 risk projections for 497 commercially exploited marine species using a systematic review and linear mixed models. Without mitigation, 92% of projections show poleward shifts averaging 50 km per decade. Paris-aligned strategies could reduce range shifts by two-thirds and extinction risk fivefold. Critical data gaps exist in regions heavily reliant on fisheries, such as South America and Southeast Asia.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は世界有数の水産物消費国であり、気候変動による漁獲可能量の変化は食料安全保障や水産業の経営に直結する。本研究成果は、日本の水産業界や政策担当者にとって、気候変動適応策の重要性を定量的に示す根拠となる。ただし、日本固有のデータや政策への直接的な言及はなく、一般的な気候変動影響評価として参照されるべきである。
In the global GX context
This study provides global quantitative evidence that climate mitigation under the Paris Agreement can substantially reduce risks to marine fisheries, reinforcing the business case for decarbonization in the seafood sector. It highlights regional data gaps, particularly in South America and Southeast Asia, which is relevant for global disclosure frameworks that require climate risk assessment across supply chains. The findings support the integration of climate scenarios into fisheries management and sustainability reporting.

📄 Abstract（原文）
Abstract The oceans host indispensable ecosystem processes and services, playing a crucial role in climate regulation and food provision. In addition to well-documented threats such as overexploitation, habitat loss, and pollution, climate change is emerging as a major driver of biodiversity loss in the oceans. Expected impacts include shifts in species distributions, altering marine biodiversity patterns, and affecting regions highly dependent on fisheries. Here, using a systematic literature review and linear mixed models, we examined ~ 1,600 risk projections for 497 commercially exploited marine species to assess the potential of climate mitigation strategies to safeguard fisheries sustainability. We provide the projected changes for all species analyzed. While most species targeted by fisheries are not projected to experience substantial reductions in range size, severe range shifts are expected. A poleward shift was found in 92% of projections, with an average displacement of 50 km per decade in the absence of climate mitigation. Strategies aligned with the Paris Agreement could reduce global range shifts by two-thirds and decrease species extinction risk fivefold compared to unmitigated scenarios. Our study also underscores critical knowledge gaps, particularly in regions heavily reliant on fisheries, such as South America and Southeast Asia. While our approach encompasses fisheries in general, future research should further distinguish the impacts across artisanal, small-scale, and large-scale fisheries. The findings reinforce the Paris Agreement as a fundamental strategy to mitigate climate-driven disruptions in fisheries and support food security, aligning with the objectives of the United Nations Decade of Ocean Science for Sustainable Development.
