本論文はブラジルの水力発電を中心とした水エネルギー・ネクサスにおける緊急河川流域管理の進化を初めて国全体で分析した。結果は、事後的な短期対策から事前の閾値に基づく標準化された体制への移行を示し、ガバナンスが分散型から集中型へと変化したことを明らかにした。水力発電依存の流域では、上流の貯水池運用と下流の水需要との調整が限定的となり、長期的な適応の柔軟性が課題となっている。
English
This study presents the first country-wide analysis of emergency river basin management in Brazil, focusing on the water-energy nexus. It finds a transition from reactive short-term measures to a standardized regime based on predefined thresholds, accompanied by a shift from decentralized to centralized governance. In hydropower-dominated basins, this centralization has limited coordination between upstream reservoir operations and downstream water demands, potentially reducing long-term adaptation flexibility.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
ブラジルの事例は、水力発電に依存する地域における水とエネルギーの統治の課題を示しており、日本でも同様の課題（特にダム運用と水需要の調整）に対して示唆を与える。集中化による迅速な危機対応と長期的な柔軟性のトレードオフは、日本の水資源管理政策の検討にも有用である。
In the global GX context
This paper contributes to the global water-energy nexus literature by empirically documenting the evolution of emergency governance in Brazil's hydropower system. It highlights the trade-offs between centralized crisis management and decentralized flexibility, relevant for countries integrating water and energy policies under climate change.

📄 Abstract（原文）
As pressures on water and energy systems increase, integrated governance of water-energy nexus has gained importance. In Brazil, where hydropower is the main source of electricity and droughts are frequent, managing this nexus is particularly challenging. This study draws on Brazil’s national resolution database to present the first country-wide analysis of emergency river basin management focused on water and energy. Results show a transition from reactive, short-term measures to a standardized regime based on predefined thresholds under a governance system that shifted the decentralized approach to a more centralized one. In hydropower-dominated basins, this shift has led to a new governance approach, with limited coordination between upstream reservoir operations and downstream water demands. Although the largely centralized governance enabled rapid crisis responses, it may limit flexibility in long-term adaptation. Recent regulatory changes, including the adoption of priority-based water rights, may help address these conflicts. However, challenges remain, and we explore the potential institutional and operational advances to ensure their effectiveness.
