Evaluating the effectiveness of ecological compensation policies helps reveal the extent of benefits, while identifying influencing factors uncovers critical bottlenecks hindering policy implementation.

To fill this gap, this paper introduces an indicator called cultivated land ecological compensation performance, which assesses the specific impacts of cultivated land ecological policies on the ecological, economic, and social systems. The spatiotemporal variations of this indicator across mainland China and its provinces were analyzed, showing an increasing trend on the temporal scale and higher values clustering in the eastern part on the spatial scale. To objectively identify the influencing factors, the XGBoost model, combined with SHAP and PDP methods, was used to explore how univariate and multivariate factors influence this indicator. Through a series of robustness tests, the results confirm the effectiveness of the XGBoost model in identifying the influencing factors. At both the national and regional levels, environmental protection expenditure, GDP, and total machinery power all have a positive impact, and the collaboration between central fiscal support and local economic development is particularly notable. The findings validate the effectiveness of policies aimed at ecological compensation and furnish an empirical foundation for policy optimization.</div></div>","PeriodicalId":309,"journal":{"name":"Environmental Impact Assessment Review","volume":"115 ","pages":"Article 108016"},"PeriodicalIF":9.8,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144134208","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 addresses these gaps by calculating HCFs across different income-age groups and analyzing household consumption patterns and associated socioeconomic driving factors in China from 2011 to 2017. Results reveal notable disparities in HCFs among age groups within the high-income bracket, which lead to the overall lower per capita HCFs of the senior group. Further decomposition analysis shows that the growth rate of per capita expenditure among elderly households, especially high-income elderly, was the slowest over the study period. As a result, from 2011 to 2017, elderly households in China contributed less to the rise in carbon emissions. According to this study, elderly households exhibit lower income-expenditure elasticity and stick to steady consumption patterns, which slows the rise in their consumption as income grows, thereby slowing the increase in their HCFs. These findings suggest that with economic growth and rising incomes, China's aging population has contributed positively to reducing HCFs in recent years.

This study addresses the research gap by integrating meta-analysis and life cycle assessment (LCA) to evaluate the potential economic and environmental consequences of broiler production using mycotoxin-contaminated feeds, a widespread issue globally. Using a representative broiler farm in the Benelux region of Europe as a model, we observed a 10.8 % reduction in feed utilization efficiency (<em>p</em> < 0.05) when birds consumed feeds contaminated with two or more EU-regulated mycotoxins (deoxynivalenol, zearalenone, fumonisin B1, ochratoxin A, and T-2/HT-2 toxin). For 100,000 birds, this inefficiency translated to 400 t of additional feed annually, costing around €200,000. In order to evaluate the environmental impacts of feed mycotoxin contamination, a comprehensive set of 19 environmental footprint categories was analyzed, including global warming potential, resource use, ecotoxicity, eutrophication, acidification, ozone depletion, and ionizing radiation. The LCA results revealed increased impacts across all categories, with an 8.5 % rise in carbon footprint and significant increases in global warming potential, acidification, and eutrophication due to heightened feed production as well as phosphorus and nitrogen excretion.

Results revealed that incineration generated significant hazardous emissions, including toluene (10.58 %, HQ = 2.90) and xylenes (4.05 %, HQ = 55.44) posing severe non-carcinogenic risks.

Specifically, vacuum pyrolysis reduced the emissions of toluene and xylene by 77.50 % and 73.58 %, respectively. Structural characterization confirmed that vacuum pyrolysis preserved fiber integrity while removing 69 % of organic resin. Therefore, vacuum pyrolysis holds certain advantages in the recovery of fibers from WTBs. Molecular dynamics simulations elucidated that pollutant formation (e.g., toluene and xylenes) stemmed from radical-driven Friedel-Crafts alkylation reactions, with incineration exhibiting higher radical diversity and pollutant yields. Compared to nitrogen pyrolysis, vacuum pyrolysis avoided carcinogenic styrene emissions and demonstrated superior cost-effectiveness.
