Agroecological approaches that value virtuous combinations of plants and animals in mixed farming conditions may support a citizen's reconciliation with animal farming, better addressing sustainability and ethics of farming. The study assesses the feasibility of transitioning to more sustainable production models by analysing poultry farming in synergy with permanent and aromatic crops, facing challenges such as environmental impact and animal welfare. This research explores the adoption of AgroSilvoPastoral Systems (ASPS), that combine plants and animals, to increase animal welfare as well as biodiversity and to reduce negative externalities. The research involved an Italian laying hen organic farm as an empirical case study. By investigating how this change can be addressed and supported by both sides of the supply chain (production and market) this study aims at proposing a novel metric for socio-economic assessments of ASPS. A gross margin evaluation and a choice experiment were utilized to determine if the changes in structural costs for producers were offset by consumers' willingness to pay for products derived from these systems. The findings indicate that implementing ASPS in egg production at a large scale could lead to a competitive advantage in the market while also promoting sustainable and environmentally friendly practices. In addition, engaging farmers in the decision-making process through a participatory approach facilitate the adoption and more efficient management of these systems, enhancing the probability of success.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"23 ","pages":"Article 100286"},"PeriodicalIF":7.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145886413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through a five-year field study employing isotopocule (δ¹⁵N^SP_N2O and δ¹⁸O_N2O/H2O) mapping, we elucidated that a 50 % substitution with manure or bio-manure significantly decreased cumulative N₂O emissions by suppressing production of nitrification- and nitrifier-denitrification- and heterotrophic denitrification (HD)-derived N₂O, and promoted N₂O reduction to N₂ in denitrification. In contrast, 20 % substitutions failed to achieve sustained mitigation. Bio-manure initially exhibited stronger N₂O mitigation than manure, but this mitigation effect disappeared over time due to a N₂O production–consumption offsetting effect in HD. Specifically, relative to manure, bio-manure stimulated HD-driven N₂O production in association with increasing abundances of HD-related genes (<em>nirK</em>, <em>nirS</em>, fungi-<em>nirK</em>) and potential denitrification rates. Bio-manure often maintained a higher capacity for N₂O reduction, evidenced by lower (<em>nirK</em> + <em>nirS +</em> Fungi-<em>nirK</em>)/(<em>nosZ</em>) ratios and unreduced N₂O fraction. Critically, substitutions enhanced crop yields, with manure increasing yields by 8–21 % and bio-manure by 19–30 % compared to conventional fertilizer. Consequently, our study revealed that 50 % bio-manure substitution is an effective strategy for mitigating N₂O emissions and enhancing yields from vegetable production systems, providing actionable insights for sustainable resource management and climate change mitigation.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"23 ","pages":"Article 100283"},"PeriodicalIF":7.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145928561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a novel internal curing strategy using activated coconut biochar (10%–30%) and hemp fiber (10–30 mm) to simultaneously address shrinkage and strength deficits. Experimental findings demonstrate that mix-sized biochar improves both the fresh and hardened properties of the concrete when compared to using small or large biochar particles alone. Notably, while the incorporation of biochar reduces fluidity due to water absorption and increased inter-particle friction, both flexural and compressive strengths were enhanced – by up to 34% and 28%, respectively – with increasing biochar content and fiber length, as a result of matrix densification and fiber-bridging effects. The synergy between biochar and hemp fibers facilitates internal curing by lowering the local water–cement ratio during hardening and promoting cement hydration through both internal curing and nucleation effects. Despite a rapid early-stage increase in drying shrinkage, the combined addition of biochar and hemp fiber ultimately achieves a remarkable reduction of up to 96%. Furthermore, increasing biochar dosage and fiber length enhances matrix compactness, substantially reducing water absorption. This, in turn, improves resistance to chloride penetration by obstructing ion transport pathways. Concrete modified with 30% biochar and 30 mm-long hemp fibers demonstrates significant potential for carbon emission reduction, achieving decreases of 4.4 kg CO₂ eq./m³/MPa in compressive scenario and 23.8 kg CO₂ eq./m³/MPa in flexural scenario.

Traditional CH₄ mitigation strategies, such as mechanical aeration, sediment capping, and vegetation management, face challenges related to high costs, inefficiency in oxygen delivery, and ecological disturbances. In recent years, interfacial oxygen nanobubbles (IONBs) have emerged as a promising geoengineering solution for reducing CH₄ emissions by providing sustained oxygenation in anoxic sediments. Unlike conventional methods, IONBs exhibit high stability, prolonged oxygen retention, and slow, controlled oxygen release, reducing the need for frequent re-application. This sustained oxygenation creates long-lasting aerobic microenvironments that suppress methanogenesis while stimulating methanotrophic CH₄ oxidation. Furthermore, IONB-loaded carriers, such as biochars and zeolites, enable targeted oxygenation, improving redox conditions and promoting beneficial microbial shifts. Compared to mechanical aeration, which rapidly dissipates oxygen, or chemical amendments requiring repeated treatments, IONBs provide a low-maintenance, cost-effective alternative with minimal ecological disruption. This review explores the physicochemical properties of IONBs, their mechanisms of action in altering sedimentary biogeochemical processes, and their potential applications in mitigating CH₄ flux from different aquatic ecosystems. Despite their potential, challenges remain in optimizing oxygen-loading capacity, assessing long-term ecological impacts, and scaling up production. Future research should focus on refining the oxygen-loading capacity of IONBs, integrating them with existing mitigation approaches, and evaluating their role in global climate policies.
