Abstract

Water pollution and scarcity are global environmental challenges. This study comprehensively assesses the integrated environmental impacts of surface water pollution and resource scarcity. The evaluation framework incorporates health impact assessment, resource loss estimation, and monetization functions. A synchronicity index is developed to analyze the dynamic and spatiotemporal heterogeneity of water pollution-scarcity interactions. A case study covering 336 Chinese cities from 2014 to 2023 is performed. The results showed that the economic valuation of integrated environmental impacts declined by 73.51%, primarily driven by significant improvements in China’s surface water quality. Furthermore, the synchronicity index analysis revealed heterogeneous characteristics of the surface water resource-environment system at the city level, demonstrating that water quality improvements have contributed to a decoupling of water pollution and resource scarcity. This study captures the complex and dynamic characteristics of the water resource-environment system, providing valuable insights for policymakers, researchers, and countries or regions facing similar water challenges to develop or adjust water sustainability management strategies.

中国城市水污染与稀缺性综合环境影响及类型特征评价

水污染和缺水是全球性的环境挑战。本文综合评价了地表水污染与资源稀缺的综合环境影响。评估框架包括健康影响评估、资源损失估计和货币化功能。建立了同步性指数，分析了水污染-水资源短缺相互作用的动态和时空异质性。案例研究涵盖了2014年至2023年中国336个城市。结果表明：综合环境影响的经济评价下降了73.51%，主要是由于中国地表水水质的显著改善。同步性指数分析揭示了地表水资源环境系统在城市层面的异质性特征，表明水质改善促进了水污染与资源稀缺的解耦。本研究捕捉了水资源环境系统的复杂动态特征，为决策者、研究者以及面临类似水资源挑战的国家或地区制定或调整水资源可持续管理策略提供了有价值的见解。

期刊介绍： The Journal of Hydrology publishes original research papers and comprehensive reviews in all the subfields of the hydrological sciences including water based management and policy issues that impact on economics and society. These comprise, but are not limited to the physical, chemical, biogeochemical, stochastic and systems aspects of surface and groundwater hydrology, hydrometeorology and hydrogeology. Relevant topics incorporating the insights and methodologies of disciplines such as climatology, water resource systems, hydraulics, agrohydrology, geomorphology, soil science, instrumentation and remote sensing, civil and environmental engineering are included. Social science perspectives on hydrological problems such as resource and ecological economics, environmental sociology, psychology and behavioural science, management and policy analysis are also invited. Multi-and interdisciplinary analyses of hydrological problems are within scope. The science published in the Journal of Hydrology is relevant to catchment scales rather than exclusively to a local scale or site.
