The field-scale practices redesign the conventional geometry of plasticulture to a compact bed (2–10 cm taller, 10–35 cm narrower) to increase input use efficiency. Life cycle assessment showed that compact bed geometry reduced GHG emissions by 6.7 %–11.4 %, and reduced input costs by 5.7 %–12.0 % per kg tomato. The reduced width from compact beds creates extra space between beds allowing more tomato per area, intensifying the system. The intensified field design reduced the GHG emissions by 2.5 % for all bed geometries, with no impact on costs, while increasing land productivity by 15 %. To increase the nutrient circularity of the system, biomass from the end-of-farm detention ponds can be harvested, composted, and applied to the fields as an organic amendment, termed harvesting-composting. Harvesting-composting decreased GHG emissions by 4–21 %, depending on the vegetation. When compact beds, intensified field design, and harvesting-composting are combined, this intensified-circular system reduces GHG emissions by up to 32 % enabling the fresh tomato industry to meet 72 % of the 2030 US GHG reduction target and 75 % of the 2030 target set by the Paris Climate Accord. The intensified system reduces irrigation volume though increased use efficiency while reducing runoff/drainage volume by decreasing the plastic-covered impervious area. When circularity is added, it increases the treatment of nitrogen and phosphorus before leaving the farm. To enable the adoption of the intensified-circular system, payments for environmental services for improving water quality, sequestering carbon, and producing more sustainable products were evaluated, and all but the carbon-based payment was significant enough to be economically feasible. The intensified-circular system has the potential to reduce 47,530 Mt. of CO₂eq and increase farm revenue up to $186 million per year for the US tomato industry.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"985 ","pages":"Article 179620"},"PeriodicalIF":8.2,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144147993","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}

After the war, between 2002 and 2007, land decontamination was carried out. This paper presents a comprehensive study of the impact of depleted uranium on soil and water in Serbia, with a special focus on contaminated locations in southern Serbia. The study includes key results from analyses of uranium isotopes ²³⁸U and ²³⁵U in soil and water, and their ratio (²³⁵U/²³⁸U) before and after land decontamination. Data from the UNEP international mission, as well as other studies from the end of the war to the present, were analyzed. Reported values of ²³⁸U and ²³⁵U in the remaining penetrators were 12.7 ∙ 10⁶ Bq/kg and 1.9 ∙ 10⁵ Bq/kg, respectively. The maximum measured values of ²³⁸U in contaminated soil were up to 307,000 Bq/kg, and ²³⁵U values were up to 3920 Bq/kg. The established ²³⁵U/²³⁸U ratios indicate that the contamination of soil with DU was near the impact sites of the penetrators, while values in more distant samples were within natural levels. It was found that the water in southern Serbia was not contaminated with DU and that the concentrations were comparable to other studies. After the remediation measures were carried out on contaminated sites, no DU presence was detected in soil or water. This is confirmed by DU monitoring results in Serbia conducted from 2013 to 2023. Additional studies for other parts of Serbia show no evidence of environmental contamination with DU, as all results are comparable to reported global values. Furthermore, to minimize any potential health risks to people, continuous monitoring of uranium at high-risk locations in southern Serbia is necessary.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"984 ","pages":"Article 179734"},"PeriodicalIF":8.2,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144134091","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}

Although relatively small-scale studies using topographically complex panels and artificial rockpools are commonplace, determining how the configuration of these interventions works over greater and more realistic spatial scales has received comparatively little attention. Given the importance of spatial variability in habitat complexity for shaping community composition and, therefore, regional diversity, filling this knowledge gap is key to enhancing the ‘design catalogue’ for future eco-engineering installations. Here, we manipulated topographic complexity using individual concrete panels placed into larger arrays to generate two different spatial configurations, and in doing so explore the potentially interactive roles of small-scale panel complexity and larger-scale variability on biodiversity. More topographically complex panels supported greater taxon richness and abundance than low complexity panels, whilst the complexity of the panels in interaction with their spatial arrangement within larger arrays influenced community composition between treatment groups. Our results corroborate studies showing how small-scale variation in surface topography benefits biodiversity, but we also demonstrate that spatial variability in how this complexity is deployed over larger areas impacts community composition. These effects were especially evident for the invasive non-native species that frequently colonise and dominate newly engineered coastal structures, often at the expense of natives. Given the ongoing expansion of coastal infrastructure, studies such as this that explore means of ‘scaling up’ eco-engineering to better represent the inherent spatial variability of natural habitats are essential to achieving biodiversity comparable to, and potentially greater than, these habitats.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"985 ","pages":"Article 179738"},"PeriodicalIF":8.2,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144134885","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}
