However, its capacity to enhance methane (CH₄) uptake and alter coupled hydrological–biogeochemical processes in urban green roofs remains poorly understood. We quantified CH₄, CO₂, and H₂O vapor fluxes over 2021–2024 in native green roof modules, comparing biochar-amended and non-amended organic-rich substrates. Across all measurement periods, green roofs functioned as consistent but weak CH₄ sinks, with biochar significantly enhancing the uptake. At peak response (Spring 2024), biochar-amended substrates exhibited more than double the CH₄ uptake of controls (−1.72 ± 0.20 vs. −0.72 ± 0.11 nmol·m⁻²·s⁻¹). In contrast, CO₂ fluxes were primarily driven by seasonal variability and showed no consistent treatment effect, whereas biochar increased H₂O vapor flux during peak growing periods. Vegetation cover increased substantially throughout the study, reflecting both plant establishment and seasonal phenological dynamics, but did not exert an independent influence on greenhouse gas fluxes after seasonal effects were accounted for. Structural equation modelling revealed that biochar enhanced CH₄ uptake in part through its effects on substrate moisture and H₂O flux, highlighting the central role of hydrological processes in regulating CH₄ uptake in native green roof substrates. Seasonality emerged as a dominant driver of substrate temperature, vegetation cover, moisture, and gas exchange, while direct temperature effects on CH₄ and CO₂ fluxes were weak in native vegetated green roof substrates. Our results demonstrate that biochar-amended native green roofs can function as persistent atmospheric CH₄ sinks while maintaining hydrological performance, identifying hydrological regulation as a key mechanism enhancing CH₄ uptake and biochar as a multifunctional amendment for strengthening the climate mitigation potential of urban green infrastructure.</p>","PeriodicalId":55126,"journal":{"name":"Global Change Biology Bioenergy","volume":"18 11","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gcbb.70187","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149205570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we focus on the cradle-to-farmgate feedstock segment of biofuel CI, the portion attributable to feedstock production from cradle to farm gate and directly influenced by agricultural management decisions. We quantify field-level cradle-to-farmgate CI of corn and soybean feedstocks by integrating a process-based model (<i>ecosys</i>) with a life cycle assessment (LCA) tool (GREET R&amp;D FD-CIC). We first identified CI uncertainty sources at a “supersite,” a representative farm in Illinois with comprehensive GHG measurements, using a Monte Carlo sampling framework that varied soil properties, management practices, and plant trait parameters across plausible ranges to quantify each source's contribution to CI uncertainty. Unknown plant trait parameters were the largest CI uncertainty source for both crops, with fertilizer information also important for corn because these inputs affect yield, N₂O emissions, and soil organic carbon (SOC) stocks. We revealed widespread field-level variability in cradle-to-farmgate CI within the same county, demonstrating the need for field-level assessment. This variability was most strongly associated with SOC change for soybean (total-effect index, 38%) and N₂O emissions for corn (43%). While inherent uncertainty is inevitable, we demonstrated that a Model-Data Fusion (MDF) approach, which integrates observational data including in situ flux measurements and satellite-based remote sensing to constrain model parameters with known processes, can substantially reduce cradle-to-farmgate CI uncertainty. Specifically, we used crop photosynthesis and yield data for plant trait parameter calibration, and incorporated tillage and cover crop information as model inputs, achieving a 41%–52% CI uncertainty reduction.

Although straw return is widely considered a resource-friendly technique for alleviating saline-alkali soils, its overall efficiency, dominant controlling factors, and optimal management levels remain unclear at the global scale. A global meta-analysis of 153 studies, 1092 paired observations, combined with machine learning methods, was conducted to quantify the effect of straw return on crop yield and major soil salinity indicators, to identify dominant controlling factors of the variability, and to optimize straw return management practices in saline-alkali soils. The results showed that straw return increased crop yield by 16.2% and reduced soil exchangeable sodium percentage (ESP) and electrical conductivity of the saturated soil extract (ECe) by 16.5% and 21.3%, respectively. Response magnitudes varied with climate, soil properties, and agricultural management. Random forest analysis further indicated that agricultural management practices were the most important factors to control changes in the crop yield, ESP, and ECe. Recommended straw return practices varied with return method and straw size: under mulching, approximately 5000–6000 kg·ha⁻¹ for straw size ≤ 5 cm and 9000–10,000 kg·ha⁻¹ for straw size &gt; 5 cm; under incorporation, approximately 4000–5000 kg·ha⁻¹ for straw size ≤ 5 cm and 5000–6000 kg·ha⁻¹ for straw size &gt; 5 cm.

Within Acrocomia genus, species such as <i>Acrocomia aculeata</i>, <i>Acrocomia totai</i>, and <i>Acrocomia intumescens</i> are of industrial interest due to their potential role in energy production. This study presents a bibliometric analysis of scientific research focused on macauba biomass, emphasizing their potential applications in bioenergy and value-added byproduct development. The analysis was conducted using RStudio and Bibliometrix, based on data retrieved from the Scopus and Web of Science databases. The resulting bibliometric data allowed for a detailed evaluation of material characterization and emerging research trends, highlighting a growing interest in biofuel production or other products, particularly biodiesel, sustainable aviation fuel (SAF), and biochar, within Brazil and South America countries.

Recent advances in biogas production include increased reactor capacity, enhanced pretreatment procedures, conductive-material-assisted digestion, and bio-electrochemical improvement. Advanced reactor designs, including biofilm-based, two-stage, and hybrid anaerobic systems, have increased biomass retention, process stability, and resistance to inhibitory chemicals. Technologies for upgrading biomethane, including scrubbing, pressure swing adsorption, membrane separation, cryogenic upgrading, biological methanation, and hybrid systems, have also made significant strides. While advanced chemical absorption techniques produced purities of up to 99.99% with less energy consumption, membrane technologies produced methane purities that were close to 98%. When combined with renewable hydrogen production, biological upgrading presents a viable route to the creation of carbon-neutral biomethane. Anaerobic digestion systems are becoming more and more capable of predictive control and optimization due to digital technologies like artificial intelligence, machine learning, Internet of Things platforms, and digital twins.

It is first revealed that, for individual biochar particles, both CH₄ and N₂O are considerably more attracted to the central aromatic sheet than to edge CC bonds and functional groups, such as carboxyl, alcohol, aldehyde, and methoxy. The nature of the oxygenated functional groups does not appear to be a key driving element, with alcohol, aldehyde, and methoxy generating quite a similar response.

Algal–bacterial consortia offer a promising platform for carbon upgrading by coupling bacterial degradation of complex substrates with photosynthetically driven biosynthesis. Carbon conversion at the cellular level is determined by metabolic pathway distribution and limited by energy and nutrient availability, while microbial interactions enhance stability and substrate use. In contrast to conventional aerobic and anaerobic treatments, which predominantly mineralize carbon, these systems promote carbon retention in biomass, thereby improving resource recovery potential.
