This study developed a scenario-based cumulative impact assessment (CIA) framework by integrating species distribution models (SDMs) to evaluate the changes in cumulative anthropogenic pressure on the habitats of iconic species under different policy futures for the Yangtze River Estuary (YRE). Three iconic species—Chinese sturgeon (<em>Acipenser sinensis</em>), Chinese mitten crab (<em>Eriocheir sinensis</em>), and Osbeck's grenadier anchovy (<em>Coilia mystus</em>)—were selected as focal species. Results indicated that pollution (38.4–43.4%) and shipping (21.7–25.8%) were the dominant pressures affecting the habitats of these focal species across all policy scenarios. Spatial analysis revealed that high-impact zones were predominantly concentrated within shipping-intensive channels. Scenario comparisons showed that Coastal and Marine Spatial Planning (CMSP) implementation significantly reduced cumulative impacts on the habitats of these focal species by 24.5%, whereas a scenario simulating the reopening of commercial fishing increased this pressure by 8.7%. This suggests that, within the modeled framework and for these specific habitats, CMSP is a highly effective policy tool for mitigating key anthropogenic pressures. Given that this analysis is derived from a linear modeling approach and focuses on habitat pressure rather than population dynamics, the conclusions should be regarded as indicative of potential spatial trends within the modeled framework. This spatially explicit, scenario-based case study highlights the value of policy-relevant habitat pressure assessments for informing the management of complex anthropogenic pressures in estuaries. The framework offers a transferable approach for anticipating spatial trade-offs in other multi-use coastal systems, underscoring the need for integrated, context-aware planning to achieve sustainable development.</div></div>","PeriodicalId":309,"journal":{"name":"Environmental Impact Assessment Review","volume":"119 ","pages":"Article 108356"},"PeriodicalIF":11.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146075272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the spatial distribution and driving mechanisms of GTI inequality across Chinese provinces, with particular attention to the influence of environmental regulation. This paper makes several innovative contributions. First, it is among the few studies that analyze green technology innovation at the provincial level, moving beyond the predominant focus on the firm level. Second, it offers a spatially explicit perspective on how environmental regulation can be optimized to mitigate regional, economic, and demographic inequalities in innovation outcomes. Drawing on provincial panel data from 2007 to 2023 and employing quantitative models, the analysis reveals that GTI is disproportionately concentrated in economically advanced and coastal regions, while central and western provinces remain lagging. In detail, compared to 2007, the level of regional green innovation in 2023 increased by 900.11%. Over the period from 2007 to 2023, the average level of green innovation was 5524.49 (measured by the number of green patent applications). The average value was lowest in 2007 (612.97) and reached its highest in 2020 (11,982.30), reflecting steady growth until 2020, after which there was a noted decline as described earlier. Looking at the average levels across the 30 provinces and cities, the mean green innovation level was 5524.49, with Qinghai Province recording the lowest average (261.76) and Jiangsu Province the highest (24,563.88).The effects of environmental regulation are found to be heterogeneous across regions: in the eastern provinces, regulation exerts no significant influence on GTI, whereas in central and western regions, stronger regulation significantly enhances innovation. Similarly, environmental regulation is less effective in areas with high levels of economic development and large population sizes, but proves more conducive to green innovation in less-developed and less-populated regions. Among the key factors shaping these outcomes are clean energy utilization, environmental protection investment, economic development, and industrial structure. These findings highlight the necessity of adopting regionally differentiated innovation policies and tailoring regulatory frameworks to local conditions.</div></div>","PeriodicalId":309,"journal":{"name":"Environmental Impact Assessment Review","volume":"119 ","pages":"Article 108365"},"PeriodicalIF":11.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146075174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing the Synthetic Control Method (SCM), this study focuses on Tianjin, a pilot city for the RURW policy and constructs a synthetic counterfactual Tianjin using non-policy provincial capitals and municipalities as the control group. This approach enables an empirical examination of how RURW allocation optimization enhances WRUL in China's first batch of pilot cities. The findings reveal that since the RURW policy implementation in 2022, this policy has gradually improved WRUL in Tianjin, with the efficiency gap between real Tianjin and synthetic Tianjin to expand over time. The mechanism analysis demonstrates that increased reclaimed water utilization directly contributes to higher WRUL in Tianjin. The findings demonstrate the essential role of RURW policy in supplementing water resource for urban development in water-scarce regions, while also contributing to the theoretical framework for evaluating such policies.

A source-oriented priority control strategy identified AMD from surrounding abandoned mines and mining-beneficiation wastewater/tailings leaching as key risk driver, with As (carcinogenic risk), Al (non-carcinogenic risk), and Cu (ecological risk) designated as priority pollutants. Monte Carlo simulation-based health risk assessment revealed significant non-carcinogenic risks and unacceptable carcinogenic risks for children, primarily driven by As and Cd, with ingestion as the dominant exposure pathway. Predictive simulations further indicate that water level recovery combined with limestone neutralization can improve water quality and reduce non-carcinogenic risks, but ecological and carcinogenic risks control have limited effectiveness. Moreover, as the model does not fully account for key biogeochemical processes, actual risks may be more severe than predicted.

Integrating PBs into AESA requires methods that express environmental impacts using metrics consistent with the PBs' control variables (CVs). However, existing PBs-based impact assessment methods mainly use proxy indicators or outdated CVs inconsistent with the latest advances in the PBs framework. This misalignment, combined with a lack of validation against empirical data, leads to unreliable and potentially incorrect interpretations of AESA results. Herein, we address these gaps by developing a novel PBs-based impact assessment method (PB-IA) that covers seven PBs and nine CVs, aligns with the latest PBs framework, and is validated against empirical data. Key advances include characterisation factors (CFs) for newly proposed CVs: functional integrity, genetic diversity, N and P surplus, as well as updates to existing CFs to improve their temporal and spatial dynamics. PB-IA provides CFs for 554 environmental flows to Exiobase v3.9.6 and is tested and validated through an environmentally extended multi-regional input–output (EE-MRIO) modelling to quantify PBs' CVs results from global anthropogenic activities. PB-IA results for five CVs are largely consistent with the latest PBs assessments and broader literature, with deviations within ±13%, thus providing an early-stage validation. Larger discrepancies for atmospheric aerosols loading, freshwater consumption, and stratospheric ozone depletion are due to differences in data structures and assumptions in Exiobase. Overall, PB-IA provides a scientifically sound and empirically validated methodology for AESA that expresses environmental pressures directly in the units of PBs' CVs. It is readily applicable to EE-MRIO and adaptable to process-based LCA, thereby supporting science-based policy and decision-making across global and sub-global scales.</div></div>","PeriodicalId":309,"journal":{"name":"Environmental Impact Assessment Review","volume":"119 ","pages":"Article 108355"},"PeriodicalIF":11.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146025610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
