However, the expansion of oil palm plantations has raised substantial environmental and socio-economic concerns. This review critically assesses the environmental impacts of palm oil biodiesel, including greenhouse gas emissions, deforestation, biodiversity loss, and the degradation of water and soil resources. Additionally, it explores the “food versus fuel” debate, emphasizing how competition for land and resources between biodiesel production and food cultivation affects global food security, particularly in developing nations. What distinguishes this review is its focus on Southeast Asian producer countries, particularly Indonesia and Malaysia, where biodiesel policies and land-use changes intersect with food and environmental systems in unique ways. Unlike previous studies, this article delves into the often-overlooked consequences of peatland conversion, highlighting its role in exacerbating carbon emissions and biodiversity loss. By providing a detailed analysis of the socio-economic trade-offs and sustainability challenges linked to palm oil biodiesel, the review offers insights into the complex interplay between renewable energy, food security, and environmental stewardship. It also evaluates technological innovations and best practices that can mitigate negative impacts. Furthermore, the review critically examines certification initiatives like the roundtable on sustainable palm oil (RSPO) and the indonesian sustainable palm oil (ISPO) and their effectiveness in promoting sustainable practices. By integrating case studies, this article demonstrates practical applications of these principles, offering actionable recommendations for policymakers, industry stakeholders, and researchers in the field.</p>","PeriodicalId":55126,"journal":{"name":"Global Change Biology Bioenergy","volume":"17 6","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gcbb.70043","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939281","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}

The effects of plant strategies on ecosystem dynamics are largely uncharacterized in bioenergy agroecosystems, where the impacts could determine bioenergy's ability to meet its sustainability goals of storing C and reducing N loss. We used FUN-BioCROP (Fixation and Uptake of Nitrogen-Bioenergy Carbon, Rhizosphere, Organisms and Protection), a plant–microbe interaction model of coupled plant nutrient uptake and soil organic matter decomposition, to simulate the effects of nutrient acquisition strategies on soil microbial activity and ecosystem nutrient cycling in bioenergy feedstocks miscanthus (<i>Miscanthus</i> × <i>giganteus</i>) and sorghum (<i>Sorghum bicolor</i> (L.) Moench). We examined the model's ability to reproduce the relative effects of belowground nutrient uptake on microbial activity using a reanalysis of empirical data showing that miscanthus root exudation provoked a larger soil microbial response than sorghum. From baseline model simulations, we found that the ability of miscanthus to retranslocate N resulted in higher N uptake at a lower C cost than the sorghum/soybean rotation and that soil C and N pools increased under perennial (miscanthus) and decreased under annual (sorghum/soybean) cultivation. The model also predicted that greater root exudation increased soil C accumulation, highlighting the role of roots in forming stable soil C. Overall, the baseline model was unable to reproduce field observations of miscanthus root exudation stimulating microbial activity more than sorghum. To improve the model, we updated the soil microbial parameters in miscanthus to have faster decomposition, a higher C/N ratio, and greater carbon use efficiency. These changes improved the simulated soil microbial response to miscanthus root exudation, supporting the hypothesis that miscanthus soils foster a microbial community that is more responsive to root exudation than that of sorghum.</p>","PeriodicalId":55126,"journal":{"name":"Global Change Biology Bioenergy","volume":"17 6","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gcbb.70042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905040","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}

It displays many desirable characteristics for this role including cold tolerance, a rapid life cycle, and a seed fatty acid profile conducive to bioenergy generation. These traits make field pennycress favorable for winter oilseed cultivation in the inland Pacific Northwest (iPNW). Simultaneously, intermediate crops are an increasingly recognized component of both agronomic sustainability and soil health management. Intermediate crops enhance soil microbial diversity, which benefits both soil and plant health. To understand the impact of field pennycress on soil microbial diversity, two natural accessions and seven experimental accessions were grown at three sites in Eastern Washington. Aboveground biomass and rhizosphere soil were then collected. Soil genomic DNA was extracted from rhizosphere samples and used to generate an amplicon library for bacterial (16S) and fungal (ITS) rRNA sequences. The resulting libraries were analyzed in QIIME2, which revealed that not only did the <i>fad2</i> deficient line from the Spring32-10 background have significantly increased aboveground biomass production compared to other pennycress genotypes, but also displayed significantly higher β-diversity in the rhizosphere community specifically at the site experiencing the driest conditions. ANCOM analysis showed that multiple sequences similar to beneficial plant and soil health enhancing organisms such as <i>Trichoderma spirale</i>, <i>Pseudomonas</i> spp., and <i>Methylobacterium goesingense</i> were found to be enriched in the microbiome of the <i>fad2</i> Spring32-10 background also at that site. To add additional context to rhizosphere community data, root exudates from two pennycress genotypes were captured in magenta boxes and analyzed using HPLC.

By analyzing whole-genome methylation, transcriptomics, proteomics, metabolomics, and photosynthesis parameters, we found that <i>P. deltoides</i> expresses specific epigenetic signatures in response to heat, resulting in improved photosynthetic efficiency compared to <i>P. trichocarpa.</i> Conversely, <i>P. trichocarpa</i> displayed stress signaling and defense mechanisms that could not sustain a net assimilation rate despite maintaining higher gas exchange. Heat stress following priming in hybrid plants increased transcript levels of thermotolerance-related transcription factors, such as <i>SPL12.</i> Selected regions in the promoter of <i>SPL12</i> showed differential methylation between direct heat stress and priming followed by heat stress. As a result, upregulation of downstream genes and associated increases in protein and metabolite abundance for stress adaptation were exhibited. Consequently, hybrid plants showed enhanced photosynthesis and gas exchange rates, a trait lacking in <i>P. trichocarpa</i>. These results imply that priming may not be universally effective in enhancing plant performance under stress, particularly in perennial tree species. However, priming can acclimate the perennial tree species <i>P. deltoides</i> to withstand elevated temperature stress better.

Biochar production presents a potential solution by creating markets for these underutilized resources.

The study identified potential locations for biochar production and developed procurement zones using delivered wood prices to evaluate biomass availability and biochar application. The minimum selling prices (MSP) for biochar were calculated for local applications to assess the cost savings. Under a baseline scenario with an average delivered biomass price of $23.25 per green ton, stationary facilities produced 71% more biochar than the estimated requirements in the Upper Peninsula (UP) but only 10% more in the Lower Peninsula (LP). Portable units, however, produced less biochar than the required application in both regions, with deficits of 4% in the UP and 50% in the LP. While stationary facilities are more cost-effective and scalable, portable units can procure more biomass and offer greater opportunities for land application of biochar. Despite a lower MSP for stationary facilities, portable units could provide a more economical option by reducing investment costs and risks. The study recommends establishing portable units in the UP and stationary facilities in the LP to optimize forest biomass procurement and biochar production in Michigan.

The research indicated that the development of studies on the topic “biochar” is widely explored, with 4259 papers being identified using the first search filter.

Among these studies, the minority included the results of calibration and validation of the models, which are paramount for the model's credibility. Therefore, efforts must be concentrated on solving the lack of valuable data to validate the models.

A European Commission 2016 impact assessment for bioenergy under the EU's Renewable Energy Directive predicted the forest sink would shrink as biomass use increased, even if sustainability criteria were required. Nonetheless, the EU adopted criteria that consider “sustainable” forest biomass to have zero carbon emissions, rendering EU and UK treatment of biomass inconsistent with IPCC's Guidance for National Greenhouse Gas Inventories. Renewable energy incentives have increased biomass use for electricity generation 1100% since 1990, but residential heating, which is ungoverned by any criteria, still represents the largest use of wood for energy in the EU. Incentives for bioenergy with carbon capture and storage (BECCS), which is intended to deliver “negative emissions,” will likely increase pressure on forests. Although IPCC Guidance is clear that BECCS fueled with forest biomass does not remove net CO₂ from the atmosphere just because carbon has been stored belowground, EU and UK climate policies rely on large-scale deployment of BECCS to meet climate targets. Bioenergy use cuts across environmental, energy, and climate policy domains; thus, reversing the accelerating decline of the forest carbon sink will require significantly better integration of renewable energy policies with climate targets and ensuring that biomass policies are aligned with international emissions reporting. Policymakers can reduce pressure on forests by disqualifying forest biomass from counting toward renewable energy targets, reducing subsidies for wood-burning, and adopting forest management policies that prioritize carbon sequestration and biodiversity. Reducing biomass harvesting and reallocating the billions currently spent on bioenergy subsidies to solar, wind, and geothermal energy is essential for restoring forests and achieving climate targets.</p>","PeriodicalId":55126,"journal":{"name":"Global Change Biology Bioenergy","volume":"17 5","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gcbb.70035","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849078","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}
