本論文はモルディブを対象に、降水量、蒸発量、観光調整済み水需要、脱塩生産量、電力関連炭素排出量を統合した月次会計フレームワークを開発した。報告された脱塩出力と設備容量・稼働率からの推測値を組み合わせ、2005～2024年の水収支を分析。脱塩拡大に伴い月平均収支が黒字から赤字に転じ、炭素排出量の削減にはクリーン電力と効率改善が必要と示唆。
English
This paper develops a reproducible monthly accounting framework for the Maldives that integrates rainfall, evaporation, tourism-adjusted water demand, desalination output, and electricity-related carbon emissions. It combines reported desalination data with inferred production from capacity and operating levels. The analysis shows that between 2005-2024, monthly water balance shifted from surplus to deficit as desalination expanded, highlighting the need for cleaner electricity and efficiency improvements to reduce carbon emissions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
モルディブの事例であり、日本とは直接関係しないが、水・炭素の統合会計フレームワークは島嶼地域や水不足地域に応用可能。日本では水資源が豊富なため優先度は低いが、観光地の水管理やエネルギー転換の参考になり得る。
In the global GX context
This paper provides a novel integrated water-carbon accounting framework at a national scale, relevant for the energy-water nexus in climate transition. While focused on the Maldives, the methodology can inform disclosure and policy in other water-scarce regions, particularly for understanding carbon implications of desalination.
👥 読者別の含意
🔬研究者:Provides a reproducible monthly framework for national water-carbon accounting that can be adapted to other island nations or water-scarce regions.
🏛政策担当者:Highlights the carbon footprint of desalination and the importance of clean energy and efficiency improvements for water supply.
📄 Abstract（原文）
Abstract Water-scarce island nations increasingly rely on seawater desalination, but national accounting of water supply, demand and associated carbon emissions is often limited. Here we develop a reproducible monthly accounting framework for the Maldives that integrates corrected rainfall estimates, evaporation, tourism-adjusted water demand, desalination production and electricity-related carbon emissions into a single national ledger. The framework combines reported desalination output with production inferred from installed capacity and operating levels. The ledger does not represent variation among islands, storage behaviour or behavioural responses in water use. Across 2005–2010, 2018–2020 and 2021–2024, the mean monthly imbalance shifts from a surplus of about 0.93 million cubic metres to deficits of about 0.43 and 0.09 million cubic metres as desalination expands. Even under optimistic rainwater harvesting assumptions, desalination supplies most water. Associated carbon emissions highlight the importance of cleaner electricity, improved efficiency and complementary rainwater harvesting and storage options.
