Whereas the approach has been applied to inform the design of global-scale sustainability scenarios based on regional perspectives, it has not been implemented to explore how local and regional scenarios can be connected across sites and scales to inform governance processes in the implementation of the SDGs. This study applies an adapted version of the Three Horizons for the SDGs approach in four sites at regional and local scales in Spanish drylands to explore its potential to support policy coherence at multiple governance scales for advancing SDG implementation through dialogue between actors from multiple sectors. We conducted four two-day in-person workshops with diverse actors (n = 59) to explore their perceptions about the desired futures, current concerns, and strategies to achieve sustainable futures in the region. Results reveal 27 similar and nine dissimilar themes related to desired futures and current concerns, respectively. These findings provide common ground and highlight different contextual realities between sites that may serve as a basis for harmonizing policy priorities for advancing regional and local SDG implementation. The study also identifies 19 themes encompassing multiple strategies with the potential to establish associations across sites and scales to coordinate actions in alignment with the 2030 Agenda. We argue that the adapted version of the Three Horizons for the SDGs approach can serve as a tool to support coherent multi-scale governance needed to achieve global sustainability goals. We discuss lessons learned and limitations encountered from using the approach that provides guidance for future experiences.</p></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":null,"pages":null},"PeriodicalIF":8.6,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142162250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Silica nanoparticles (SiNPs) are demonstrated as an eco-friendly option for diseases management, but the specific mechanisms behind their ability to confer disease resistance in wheat have not been adequately characterized. This study evaluates the impact of SiNP200 on the resistance of wheat to FHB. Scanning electron microscope observation showed that SiNPs form a physical barrier on the surface of wheat leaves. Pathogenicity tests indicated foliar application of SiNP200 can protect wheat against F. graminearum, resulting in a significant reduction of lesion length by 27.7%, but in-vitro cultivation showed that SiNP200 had no impact on pathogen growth. Antioxidant enzyme activity analysis showed that SiNP200 had little effect on H2O2 contents, POD, and CAT activities under non-stress conditions, but under F. graminearum infection conditions, SiNP200 increased POD and SOD activities while decreased CAT and DHAR activities, and GSH content. Histochemical staining indicated that SiNP200 decreased ROS accumulation, thus reducing oxidative damage. Meanwhile, SiNP200 decreased MDA and Pro contents. Furthermore, SiNP200 increased SA response marker genes (TaPR1a, TaPR2 and TaPR5) expression levels and SA content, contributing to the enhanced wheat resistance to FHB. Summarily, SiNP200 improve wheat resistance to FHB, thereby providing a theoretical basis for SiNP200 application to control this disease.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":8.131,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142160527","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}

Especially, the impacts of bioremediation on soil co-contaminated with benzene, toluene, and trichloroethylene (TCE) have seldom been comprehensively evaluated yet. In this study, the contributions of biostimulation, bioaugmentation, and their combination for the bioremediation of the co-contaminated soil containing benzene, toluene, and TCE were systematically investigated. The addition of nutrients ((NH₄)₂SO₄ (as N source), K₂HPO₄ (as P source), vegetable oil and CH₃COONa (as C sources)) enhanced the degradation efficiency of the co-contaminated soil by 10.19% to 49.62%. The optimal biostimulation condition involved using vegetable oil as the carbon source with a C: N: P ratio of 100: 10: 1. Meanwhile, the addition of the microbial cultures screened and domesticated from the co-contaminated soil, named B-T, effectively enhanced the removal rate of contaminants by 33.02% to 37.55%. The genera comprising <i>Pseudomonas</i>, <i>Stenotrophomonas</i>, and <i>Chryseobacterium</i> in B-T exhibited the highest relative abundance, suggesting their potential for the removal of benzene, toluene, and TCE. Besides, the coupling of biostimulation and bioaugmentation enhanced the degradation efficiency by 62.38% to 68.84%, showing the most effective biodegradation effects. The coupled strategy showed synergistic effects of both, increasing the quantity and activity of microorganisms and accelerating the biodegradation of target contaminants.

It was shown that the yeast Debaryomyces hansenii is not susceptible to the toxic effect of copper and could be effectively used with a nanostructured electrode in the ferrocene-methylene blue dual-mediator system. Paracoccus yeei bacteria are susceptible to the toxic effect of copper ions, therefore, their immobilization on the nanostructured electrode was carried out using the redox-active polymer poly(neutral red), which protects microorganisms from negative effects and allows effective conjugation of microorganisms with the surface.

In the present study, we investigated the potential impacts of biodegradable nanocarriers after one biocompatible dose that could promote sustainable treatment against enteropathogens.

Anaerobic bioreactors containing fresh slurry collected from pig intestines were used to simulate the anaerobic gut microenvironment. Bioreactors were inoculated with empty NPs with concentrations identical to loaded nanoparticles and free Enro, PLGA (Enro) (PE), and LIGNIN(Enro) (LE) that present antimicrobial activity and non-cytotoxicity to pig intestinal cells. Slurry aliquots from the bioreactors were collected for RNA extraction after 24, 48, and 72 hours of exposure to the drug and nanocarriers for microbial 16S rRNA metatranscriptomics and resistome analysis. Our results showed that PLGA and PE microbial communities were similar over all periods despite containing Enro. The impact of LIGNIN on the microbial community was minimal since it was similar to the control. However, loaded LE significantly reduced the microbial diversity but maintained essential estimated metabolic functions. Free Enrofloxacin affected the microbial community the most by decreasing the core gut microbiome diversity. Our results indicate that NP encapsulation of antibiotics delayed the increase in antibiotic resistance genes (ARG) expression between 24 and 72 hours compared to free Enro.
