気候変動が水質と水不足に与える影響を、部門別（家庭、灌漑、畜産、製造、エネルギー）の水需要と水質要件を考慮した全球モデルで評価。2100年までに世界人口の約67%が深刻な清浄水不足に直面し、製造業と火力発電部門で水ギャップが20%拡大すると予測。水質と水量の統合的管理の必要性を強調。
English
This study uses a global modeling framework to assess future cross-sectoral clean water gaps, considering both water quantity and quality under climate change. Results show that by 2100, nearly 67% of the world's population will face severe clean water gaps, with manufacturing and thermoelectric sectors experiencing a 20% increase in water gaps relative to demand, mainly due to rising water temperatures. The findings underscore the need for integrated water management strategies addressing both quantity and quality.

📄 Abstract（原文）
While the impact of future climate change on physical water availability has been extensively studied, the interplay with water quality and the associated impact on water scarcity-particularly the ensuing competition among sectors (domestic, irrigation, livestock, manufacturing, and energy) for clean water-is less well understood. Here we employed a globally applicable modelling framework to assess future cross-sectoral clean water gaps arising from competition for limited clean water resources, explicitly accounting for sector-specific water quantity and quality requirements under global change. Our results show that deteriorating water quality and insufficient water quantity will severely exacerbate future water gaps, exposing nearly 67% of the world's population to severe clean water gaps by 2100. As a result, cross-sectoral competition for clean water will greatly intensify, with disproportional impacts on the manufacturing and thermoelectric sectors, each facing a 20% increase in water gaps relative to their demands, primarily related to rising water temperatures. Overall, our findings underscore the need for integrated water management strategies that address both water quantity and quality to mitigate growing competition for clean water.
