Based on China's low-carbon city pilot policy (LCCP), we systematically evaluated the entrepreneurial effect and mechanism of LCCP through a quasi-natural experiment. The study found that LCCP significantly promotes entrepreneurship, and this conclusion remains valid after a series of robustness tests. The mechanism analysis shows that technological innovation, talent agglomeration, industrial upgrading, and financing facilitation are important channels through which LCCP stimulates entrepreneurial vitality. Heterogeneity analysis found that LCCP’ impact on entrepreneurship is more pronounced in southern regions and in cities with more advanced economies, higher carbon emissions, and less industrial specialization. Further research found that LCCP inhibits entrepreneurship in neighboring cities, but can curb the strategic relocation behavior of polluting enterprises. The research conclusions not only enrich the research on the social impacts of low-carbon transition, but also provide new ideas and perspectives for interregional environmental governance in China from a spatial perspective.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"381 ","pages":"Article 125247"},"PeriodicalIF":8.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We ask whether the system's purpose (nutritionally oriented) and design can significantly impact sustainable intensification performance. The design of four agricultural systems ranging from monoculture to crop diversification gradients and crop-livestock integration for protein and energy (calories) reinforcement are compared for a four-year production cycle using a strong sustainable approach supported by the thermodynamic law: emergy assessment. The findings suggest that (i) crop-livestock integration and crop diversification increase renewability and reduce the unsustainability of agricultural systems; (ii) crop-livestock integration promotes sustainable intensification for both protein and energy purposes; (iii) increased crop diversification over the system cycle doesn't mean increased sustainability of protein or energy intensification, and (iv) the system's purpose defines the optimal design for sustainable intensification. We conclude that both the purposes and design of agricultural systems are relevant for nutrition-oriented sustainable intensification and require long-term assessments to reinforce such assertions.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"381 ","pages":"Article 125253"},"PeriodicalIF":8.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Amphibians are especially affected because they depend on both aquatic and terrestrial habitats to complete their life cycles, which can be negatively impacted by roads, due to reduced landscape connectivity. Understanding animal movement across the landscape may improve the prioritisation of sites to implementing mitigation measures. We assessed landscape connectivity using circuit theory, for two amphibian species (the Iberian spadefoot toad and the Iberian ribbed newt) on a Mediterranean landscape in Southern Portugal. We addressed the following question: Can landscape connectivity predict amphibian roadkill risk? Our connectivity models assigned higher current movement corridors to heterogeneous habitats composed of sparse forests combined with low-management agricultural areas and good networks of higher-density water bodies. We found a positive correlation between high-connectivity road segments and roadkill for both species, proving that landscape connectivity can be a valuable tool to predict locations with higher roadkill probability.</div><div>We acknowledge that maintaining a heterogeneous landscape, with a higher density of short-distance water bodies that connect highly suitable habitats is important for amphibians.

The high-speed stirring had remarkable removal effect on saturated hydrocarbons, aromatic hydrocarbons and resins. In addition to the three components mentioned above, thermal-activated Na₂S₂O₈ also had excellent removal effect on asphaltenes in the cleaned oily sludge based on the strong oxidation effect of SO₄⁻· and OH·. This work demonstrates a new method to treat oily sludge efficiently, which not only reduces the burden of petrochemical industries and provides support for their green development, but also has important scientific significance for environmental protection and environmental management.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"381 ","pages":"Article 125230"},"PeriodicalIF":8.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study focuses on the in-situ growth of MOF—AlFu on ceramic filters (CFs), thereby synthesizing in-situ MOF-modified ceramic filters (IMCFs) for effective fluoride removal from drinking water in such communities. Initially, we conducted response surface optimization of the IMCF preparation process, followed by comprehensive characterization. Based on SEM, XRD, and FTIR analyses, it is confirmed that AlFu successfully grows on the surfaces and within the pores of CFs, forming layered structures that enhance the effective adsorption of fluoride on IMCFs. Besides, zeta potential and FTIR results indicated that electrostatic adsorption, ion exchange and hydrogen bonding are the primary mechanisms of fluoride adsorption on IMCFs, which is also confirmed by the adsorption kinetics. The results of adsorption isotherms show that the maximum adsorption of IMCFs is 9.51 mg/g. Within the pH range of 4–10, IMCFs reduced the fluoride concentration from 10 mg/L to below 1.2 mg/L. Furthermore, the IMCF retains over 75 % of its adsorption capacity after undergoing five use cycles, exhibiting remarkable durability during the multiple cycling filtration process.

Two previous studies examined the extent to which designation results in reduced light emissions by comparing the upward radiance of designated communities to non-designated communities using Visible Infrared Imaging Radiometer Suite Day-Night Band (VIIRS DNB) upward radiance satellite data. This study compares sky brightness trends using linear regression between designated communities and non-designated communities in Central Texas and inside the Greater Big Bend International Dark Sky Reserve. For this study, VIIRS DNB was used as input for the National Park Service All Sky Light Pollution Ratio (ALR) sky brightness model to determine mean sky brightness from 2012 to 2022. Additional requirements were added to this study to determine non-designated communities used for comparison. Ground measurements were also taken from 2023 to 2024. Of the designated communities in the study, 69 % showed no difference in trends or a greater upward trend compared to their control community while 31 % showed either no overall change or a smaller upward trend in sky brightness compared to their control community. There was an upward trend in sky brightness for 93 % of the places in the study. Ground measurements showed 90 % of dark sky places were darker than their control community.
