本研究は、気候変動に伴う水とエネルギーの安全保障のための適応策を経済的に最適化する多目的最適化モデルを提案。25か国のデータを用いた分析では、事前適応投資の便益費用比が2.4～11.8であり、水・エネルギー連携アプローチにより適応コストを18～34%削減できることを示した。
English
This study presents a multi-objective optimization model for climate adaptation in water and energy sectors, integrating cost-benefit analysis with climate risk and infrastructure vulnerability measures. Analyzing 25 countries, it finds benefit-cost ratios of 2.4-11.8 for proactive investments, and a water-energy nexus approach reduces adaptation costs by 18-34% compared to sector-based planning.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は水資源とエネルギー安全保障の両面で気候変動適応が急務だが、本論文は世界25か国対象の一般的手法を提供。水・エネルギー連関の経済評価フレームワークは、日本のインフラ強靭化や適応投資の優先順位付けに応用可能。特に、水害リスクが高まる日本において、適応策の費用対効果を評価する実践的ツールとなり得る。
In the global GX context
Globally, the water-energy nexus is critical for climate adaptation and resilience. This paper offers a testable, data-driven economic optimization framework that quantifies synergistic benefits of integrated planning, providing evidence for policymakers and investors to prioritize cross-sectoral adaptation investments, particularly relevant under the UNFCCC adaptation framework and green finance initiatives.
👥 読者別の含意
🔬研究者:Researchers in climate adaptation and water-energy nexus can use the integrated cost-benefit optimization model as a template for region-specific analysis.
🏢実務担当者:Water and energy managers can apply the framework to prioritize adaptation investments and quantify the co-benefits of a nexus approach.
🏛政策担当者:Policymakers can leverage the benefit-cost ratios and cost reduction estimates to justify proactive adaptation funding and integrated infrastructure planning.
📄 Abstract（原文）
The world faces unprecedented demands on water and energy infrastructure because of climate change, and a massive economic structure is needed to enable adaptation planning. This study presents a combined cost–benefit analysis that can be used to analyze climate adaptation strategies in the water and energy sectors. Our model is a multi-objective optimization model, where climate risk measurement, infrastructure vulnerability measurement, and economic evaluation of the measures for adaptation are combined. The proposed methodology uses indices of climate resilience, net present value (NPV), and benefit–cost ratio (BCR) to evaluate the efficiency of climate-adaptation investments. We analyze the adaptation scenarios of 25 countries based on available datasets on the World Bank Climate Change Knowledge Portal and from the International Energy Agency (IEA). The results show that the benefit–cost ratios for proactive adaptation investments range from 2.4 to 11.8, including high pay-off for investments in the water sector in drought-prone locations. The water–energy nexus approach shows there are synergistic benefits that can reduce the overall costs of adaptation by 18%–34% compared to that of sector-based planning. The study also provides a testable and valid economic decision support framework that enables water and energy resource managers to target climatic adaptation investments to the water–energy nexus, helping to facilitate the transition to creating more resilient infrastructure.
