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. As an innovative and sustainable tool, IONBs hold great promise for advancing wetland conservation, reducing agricultural CH₄ emissions, and climate change mitigation efforts.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"22 ","pages":"Article 100256"},"PeriodicalIF":7.8,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144827511","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}

Great variation of NANI and NAPI evolution patten was found in different regions. Eastern and southern provinces (e.g., Henan, Shanghai) had the highest inputs, while western regions (e.g., Tibet) had the lowest, correlating with economic and population density disparities. Spatial clustering highlighted the need for region–specific nutrient management strategies. Dietary shifts showed increased animal–based food consumption (6.89–fold rise) and urban–rural disparities, with developed regions exceeding recommended intake levels. Driving factors for NANI and NAPI differed by regions of different development stage. Urbanization and GDP were dominant drivers in developed areas (Type I), while population was key in less–developed regions (Type II).

This premise was explored through a Japanese consumer survey analyzing factors influencing both adoption and rejection as well as key acceptance criteria across thirty diverse product types. The results revealed nuanced attitudes toward secondhand items. Hygiene and cleanliness were paramount for items with direct skin contact, while privacy concerns dominated for tablets. Notably, childhood-related items were often kept for sentimental value rather than being reused. Bulky furniture and small electronics were frequently stored or discarded due to the perceived inconvenience of reuse procedures. The study identified two consumer acceptance factors in online C2C markets: (1) the product condition and functional assurance and (2) product information and market appeal. Consumer decisions prioritized different factors depending on product type: hygiene-sensitive items required consideration of both factors, everyday wear showed less sensitivity to either, electronics emphasized product information and appeal, and life-stage products prioritized condition and functionality. These diverse preferences highlight the importance of product-specific strategies, which can foster consumer trust and facilitate robust secondhand transactions. Ultimately, by building trust, streamlining transactions, and acknowledging diverse product needs, businesses and policymakers can promote reuse and drive widespread adoption of secondhand products towards a sustainable consumption system.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"22 ","pages":"Article 100250"},"PeriodicalIF":7.8,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144865356","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}

The United Nations’ Sustainable Development Goal 12.3 aims to halve global food waste by 2030, linking waste reduction to hunger alleviation. California sought to address both priorities simultaneously through Senate Bill (SB) 1383, a novel organic waste law. This article contributes to the literature on food loss and waste (FLW) mitigation by examining tensions between SB 1383’s dual goals: diverting organic waste from landfills and redistributing surplus food to communities in need. While SB 1383 is a progressive policy, its implementation has revealed conflicts between these objectives. We assess the impact of SB 1383 on stakeholder compliance with its food waste reduction and recovery requirements. Specifically, we examine the two key objectives of this regulation: (1) mitigating climate change by diverting organic waste from landfills, and (2) addressing food insecurity by redistributing recovered food to communities in need. We interviewed 37 stakeholders, including food recovery organizations, jurisdiction representatives, and edible food generators involved in implementation. Additionally, we analyzed the distribution of Local Assistance Grant funds across California counties and between the policy’s dual goals. Our findings indicate a stronger focus on waste diversion than food recovery, and an uneven distribution of funding, with rural areas facing greater challenges in adapting to SB 1383’s requirements. We conclude by highlighting tensions in FLW policy design that seeks to advance multiple, sometimes competing, goals.</div></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":"22 ","pages":"Article 100252"},"PeriodicalIF":7.8,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144860454","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}
