タイ・チョンブリ県を事例に、汚染拡散・海洋保護区最適化・ブルーカーボン・海岸侵食リスクの4モデルを統合した課題志向型の海洋空間計画（MSP）枠組みを提案。InVEST-HRAモデルと空間重ね合わせ分析により、人為的海洋活動が生息地変化の主要因であることを特定し、5沿岸域のリスク空間勾配を明示。ステークホルダー参加を経てMPA9.47%・開発区域28.46%を含むゾーニング案を構築し、グローバルサウスにおける生態系ベース管理と行政執行の橋渡しを示した。

English

Using Chonburi Province, Thailand as a case, this study proposes an issue-oriented marine spatial planning framework integrating four thematic models: pollutant diffusion, MPA optimization, blue carbon mapping, and coastal erosion risk. Spatial overlay and InVEST-HRA modeling identify anthropogenic maritime activities as the primary driver of habitat change, revealing spatial risk gradients across five coastal zones. Stakeholder engagement produced a zoning scheme with MPAs (9.47%) and Marine Development Areas (28.46%), offering a scalable pathway for ecosystem-based management in the Global South.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本は海洋基本計画やブルーカーボン生態系のJ-クレジット化を進めており、沿岸域の多主体調整とゾーニング手法は日本の沿岸管理・自治体計画に示唆を与える。ただし炭素クレジット定量や企業開示との接続は薄く、GX実務への直接応用は限定的。

In the global GX context

Blue carbon and marine spatial planning are increasingly relevant to global climate disclosure, particularly as nature-related frameworks (TNFD) and blue carbon credits gain traction. This paper's integrated zoning approach offers a replicable model for coastal nations balancing conservation with development, though it stops short of quantifying carbon stocks for disclosure or credit markets.

👥 読者別の含意

🔬研究者:統合モデリングとステークホルダー参加を組み合わせた課題志向型MSPの方法論は、沿岸ガバナンス研究に有用な枠組みを提供する。

🏢実務担当者:ブルーカーボンや沿岸リスクを事業立地・サプライチェーン評価に組み込む際の空間データ統合アプローチとして参考になる。

🏛政策担当者:グローバルサウスにおける生態系ベース管理と行政執行のギャップを埋めるゾーニング手法は、沿岸政策立案に示唆を与える。

📄 Abstract（原文）

While Marine Spatial Planning (MSP) is globally recognized as a strategic tool for ocean governance, its implementation in tropical coastal regions faces distinct challenges stemming from fragmented governance and acute conflicts between traditional livelihoods and modern industries. To address these complexities, this study proposes an issue-oriented MSP framework designed for high-intensity development zones. Taking Chonburi Province, Thailand, as a representative case study, we integrated four thematic models—hydrodynamic pollutant diffusion, marine protected area optimization, blue carbon mapping, and coastal erosion risk assessment—to quantify the spatial compatibility between anthropogenic activities and sensitive habitats. Integrating spatial overlay analysis of thematic outputs with InVEST-HRA modeling, this study identifies anthropogenic maritime activities as the primary driver of habitat change across Chonburi Province. The assessment reveals pronounced spatial heterogeneity in risk across five key coastal zones: military activities exhibit a stable risk profile, coastal tourism demonstrates consistently low ecological impact, and fisheries and maritime transport emerge as the principal manageable variables—displaying a clear spatial gradient in risk levels. Through stakeholder engagement, this process culminated in a comprehensive zoning scheme comprising two primary zones—MPAs (9.47%) and Marine Development Areas (28.46%)—along with seven secondary sub-zones. This work demonstrates that issue-oriented, data-integrated zoning can effectively reconcile multi-sectoral trade-offs, offering a scalable pathway for bridging the gap between theoretical ecosystem-based management and practical administrative enforcement in the Global South.
