This study proposes a Physics-Informed Multi-Agent Reinforcement Learning (PI-MARL) framework for sustainable transboundary water management under climate uncertainty. Validated in the Yarlung Tsangpo-Brahmaputra River Basin, the AI agents learn cooperative, pre-emptive release strategies, reducing downstream flood peaks by 16.3% and increasing system reliability to 99.2%. The closed-loop control shifts hydro-political challenges from operational micro-management to objective macro-negotiation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本においても気候変動適応策としての水管理は重要だが、本論文の焦点は中国・インド国境地帯であり、直接的な日本のGX文脈とは距離がある。ただし、AIを用いたリアルタイム制御の知見は、日本のインフラ管理に応用可能性がある。
In the global GX context
This paper addresses climate adaptation in transboundary water management using AI, a topic relevant to the broader sustainability and climate risk discourse. While not directly about decarbonization, it demonstrates algorithmic real-time control replacing static quotas, which could inform adaptive governance in global GX contexts.

📄 Abstract（原文）
Sustainable transboundary water management is increasingly compromised by climate-induced deep uncertainty, as traditional open-loop strategies fail to adapt to non-stationary hydrological shifts and physical propagation time-lags. To overcome these structural rigidities, this study proposes a Physics-Informed Multi-Agent Reinforcement Learning (PI-MARL) framework. Operating as a closed-loop controller, it maps real-time basin states-explicitly accounting for physical routing delays-to optimal release decisions. Empirical validation in the Yarlung Tsangpo-Brahmaputra (YTB) River Basin reveals that AI agents autonomously learn cooperative, pre-emptive release strategies to achieve spatio-temporal risk substitution. Crucially, this robust coordination emerges through decentralized real-time execution, provided riparians agree upon a hybrid reward structure that internalizes transboundary risks. This effectively shifts the hydro-political challenge from operational micro-management to objective macro-negotiation. Rigorous stress testing under calibrated stochastic extreme events confirms that this AI-driven approach significantly outperforms traditional static baselines, reducing downstream flood peaks by 16.3% and elevating system reliability to 99.2%. By quantifying the value of information flow underpinning this mechanism, our findings provide a scientific foundation for transitioning transboundary governance from rigid quotas to adaptive, algorithmic real-time control.
