Previous work developed subjective supply risk indicators to approximate this probability, typically combining several factors such as supply diversity and trading partners’ political stability, where indicator weightings can substantially impact results. This work explicitly quantifies export barrier probability using an ensemble of machine learning classifiers, with probability estimates informed by exogenous variables, including prior barrier implementation and global export dominance. Major differences in high-probability countries and commodities are observed across models, but the ensemble method highlights Indonesia, China, Tanzania, and the United States as particularly high risk.

Most existing studies focus on a single region, lacking comprehensive analysis of the impacts of various types of dams on land use and land cover change (LULC) and landscape patterns as well as their gradient effects at a global scale. This study systematically analyzed the impact of global dams on the surrounding environment within 5-km gradient buffer zones, utilizing data from 6763 dams constructed between 1984 and 2018 in the Global Dam Tracker (GDAT) and the GLC_FCS30D global 30 m LULC data (1985–2020), alongside land use dynamics and landscape pattern indices. The results showed that from 1984 to 2018, new dams were primarily built in developing countries in Asia (3277 dams) and Africa (2079 dams) in the last 35 years. The majority of these dams were built for irrigation (32%) and hydroelectric power (20%). The construction of these dams resulted in a 120% increase in impervious surfaces and a 6% deforestation rate within the 5-km buffer zone, and the integrated land use dynamicity in the near-dam zone (0–2 km) was significantly higher than in the far-dam zone. Among them, irrigation dams exhibited the steepest distance decay rates, indicating the strongest impact on the surrounding land-use dynamics. After 1995, there was an increase in landscape fragmentation (patch density (PD)) and Shannon’s diversity index (SHDI) increased, while the aggregation index (AI) and mean patch area (AREA_MN) decreased. Our study provides a reference base for assessing the ecological effects of dams and managing them sustainably around the world.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"229 ","pages":"Article 108832"},"PeriodicalIF":10.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146116408","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}

Focusing on the transition in Chinese residents' dietary structure, and based on demonstration plant data corresponding to four mainstream bioenergy technologies, this study analyzes the dynamic changes in the bioenergy supply chain under evolving dietary trends. By extending the Bass diffusion model to simulate the penetration effects of bioenergy technologies, the energy supply and emission reduction potential of AWB from 2023 to 2045 are evaluated. The findings reveal that: (1) The power generation cost of demonstration plants exhibits a significant positive correlation with biomass collection radius, but a negative correlation with biomass distribution density. (2) Although no fundamental shift has occurred in Chinese dietary patterns, meat demand (286.8∼304.8 kg per capita) has gradually surpassed that of grain crops (248.7∼250.2 kg per capita), resulting in an approximate 55.3% increase in livestock manure production. This growth leads to a reduction in the power generation cost of livestock manure, with a decrease ranging from –0.021 to –0.039 CNY/kWh. (3) Among the four technologies considered, Heilongjiang, Henan, and Shandong provinces demonstrate outstanding comprehensive performance, each achieving a comprehensive score above 0.7.

However, an increasing number of studies have confirmed that MPs entering the soil can interfere with the stability of the microbial community structure and affect the nutrient cycling processes driven by microorganisms in the soil, thereby affecting greenhouse gas emissions and plant growth. Our understanding concerning the effects of MPs on element cycling, enzyme activity, and microbial gene expression remains unclear. The present review focuses mainly on the effects of MPs on carbon (C), nitrogen (N), and phosphorus (P) cycling on soil and plant responses and introduces related advancements, challenges, limitations, and future directions. MPs can significantly affect soil C, N and P cycles and functional microorganisms in soil and correspondingly alter enzyme activities and gene expression related to greenhouse gas emissions (CH₄ and N₂O), depending on the interactions between the characteristics of the MPs themselves and the soil environment (e.g., moisture status, redox potential, and the microbial community). Despite the rapid development of life cycle assessment, carbon footprint and sustainable development goals related to MPs, this is still a challenging frontier field, reflected mainly in data gaps and standardization, indistinction of the carrier effect, and incompletion of the impact assessment model. Currently, several controversies remain concerning whether the same MPs have varying effects across different soil types; findings from short-term laboratory experiments often conflict with long-term field data, and MPs ultimately enhance or suppress plant absorption of N and P. This review proposes several valuable suggestions for future research, including long-term field experiments, multifactor interactions, molecular ecology techniques, standardized research methods, and coregulatory effects of viruses and hosts, which will narrow the knowledge gap concerning MPs-mediated element cycles in soil.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"228 ","pages":"Article 108788"},"PeriodicalIF":10.9,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145980696","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}

This lowers the reaction activation energy, enabling high leaching efficiencies for Ag (99.5%) and Al (94%) while markedly reducing the required nitric acid dosage. Subsequent CTS, with its ultrafast heating, overcomes the kinetic limitations of silica reduction, rapidly converting the acid-leached Si residue into high-purity, highly crystalline SiC. The synthesized SiC is well suited for high-temperature electronic devices and thermal management applications due to its excellent thermal stability, high thermal conductivity, and semiconducting properties.
