タジキスタンとキルギスは中央アジアで最も水力発電依存度が高い国の一つであり、雪氷融解に由来する河川流量の変化に脆弱である。本レビューは、気温上昇・氷河後退・水文変動性の増大が河川流量と貯水池流入の不確実性を高め、水力発電計画と長期エネルギー安全保障に課題をもたらすと指摘する。水力は主要電源であり続けるが、太陽光・風力・地熱・バイオマスの補完的開発により水文リスクの集中を緩和できるとし、気候を踏まえたエネルギー計画、インフラ近代化、水文・気候情報の改善、越境水・エネルギー協調の重要性を強調する。
English
Tajikistan and the Kyrgyz Republic are among Central Asia's most hydropower-dependent countries, with systems fed by mountain snow and glacier melt. This review finds that warming, glacier retreat and rising hydrological variability increase uncertainty in river flows and reservoir inflows, challenging hydropower planning and long-term energy security. Hydropower will remain dominant, but solar, wind, geothermal and biomass diversification could reduce concentrated hydrological risk. It stresses climate-informed planning, infrastructure modernization, better hydro-climate data and transboundary water-energy coordination.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業・投資家にとって直接の開示規制接点は薄いが、水力依存電源の気候物理リスク評価はTCFD・ISSBの物理リスク開示を検討する際の参考事例となる。中央アジアの電力・水資源案件に関与する商社やインフラファンドには示唆がある。
In the global GX context
Adds a Central Asian, hydropower-heavy case to the global physical climate-risk literature relevant to TCFD/ISSB physical-risk disclosure and transition planning for hydro-dependent grids. It underscores transboundary water-energy governance, an under-covered dimension in mainstream climate disclosure scholarship.

📄 Abstract（原文）
Tajikistan and the Kyrgyz Republic are among the most hydropower-dependent countries in Central Asia, with electricity systems strongly influenced by mountain snow and glacier-fed river flows. Hydropower provides important benefits for energy security, economic development, and regional electricity trade, but this dependence also creates vulnerability to changes in water availability and seasonal hydrological conditions. This review examines the energy systems of Tajikistan and the Kyrgyz Republic, focusing on hydropower development, energy-sector challenges, climate-related changes in glaciers and hydrology, renewable-energy diversification, and transboundary water–energy management. The review synthesizes evidence from scientific literature, international organizations, government sources, and other publicly available materials. The findings indicate that rising temperatures, glacier retreat, changes in snow and melt dynamics, and increasing hydrological variability may increase uncertainty in river flows and reservoir inflows, creating additional challenges for hydropower planning and long-term energy security. Although hydropower is expected to remain the principal source of electricity in both countries, complementary development of solar, wind, geothermal, and biomass resources could reduce the concentration of hydrological risk. The review also highlights the importance of climate-informed energy planning, infrastructure modernization, improved hydrological and climate information, and stronger transboundary water–energy coordination. Overall, long-term energy resilience in Tajikistan and the Kyrgyz Republic will depend on integrating hydropower development with renewable-energy diversification, climate adaptation, and regional cooperation. Further quantitative research is needed to assess climate impacts on hydropower generation and the technical and economic feasibility of alternative energy pathways under future climate conditions.
