エクアドルを対象に、水ストレスシナリオ（降水量15%減）による水力発電量の減少（2050年に32PJ/年）と、燃料油・天然ガス・バイオマスによる代替、適応コストの累積増加（32.5億ドル）を定量化。太陽光発電の導入は運用制約から限定的で、耕地喪失による経済損失も評価。CLEW分析を損失・損害基金への申請手法として提案。
English
This CLEW analysis for Ecuador (2020-2055) quantifies impacts of water stress: hydro generation drops by 32 PJ/year by 2050, replaced by fossil fuels and biomass; adaptation costs reach $3.25 billion cumulatively; solar generation is constrained operationally; loss of 1.31 million hectares of arable land costs $1.48 billion/year. Recommendations include integrating adaptation costs into loss and damage estimates and using CLEW for UNFCCC fund applications.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも水力発電の水リスクは無視できず、適応コストの定量化手法は参考になる。ただしエクアドル特有の条件が強いため直接適用には注意。
In the global GX context
Provides a quantitative framework (CLEW) for assessing climate-induced water stress on energy systems and adaptation costs, relevant to the UNFCCC Loss and Damage Fund and energy planning in water-dependent regions.
👥 読者別の含意
🔬研究者:Offers a replicable CLEW methodology for integrating water-energy-land nexus in climate risk assessments.
🏢実務担当者:Useful for energy planners in evaluating trade-offs between hydro, solar, and fossil fuels under water scarcity.
🏛政策担当者:Demonstrates how to quantify adaptation costs and losses for national submissions to the UNFCCC Loss and Damage Fund.
📄 Abstract（原文）
This CLEW analysis for Ecuador 2020–2055 examines three trajectories: Baseline, Water Stress Scenario (15% reduction in precipitation by 2050, consistent with IPCC AR6 SSP2-4.5), and Optimized Solar Cost Scenario (reduction in solar cost from $1,524.53/kW to $240/kW by 2055). Four findings: (i) Water Stress reduces hydroelectric generation by −32 PJ/year by 2050, offset by fuel oil, natural gas, and biomass; (ii) adaptation costs amount to +$3,253 million USD cumulatively (+2.24%), with an annual penalty of $367 million USD in 2050; (iii) solar generation does not exceed 13.57 PJ/year due to operational, not economic, constraints; (iv) The loss of 1.31 million hectares of arable land by 2050 is quantified, with an economic loss of $1.482 billion USD per year. Four recommendations: incorporate the cost of energy adaptation into the analysis of loss and damage; complement solar policies with priority storage and dispatch; review the biofuels mandate; and use CLEW quantification as a methodological basis for interacting with the UNFCCC Loss and Damage Fund.
