An analysis of environmental and economic impacts of the system of rice intensification : A case study in Thai Binh Province, Vietnam

The current research investigates the environmental and economic impacts of the system of rice intensification. Rice, a fundamental staple in our diets, is paradoxically a significant contributor to greenhouse gas emissions, fueling global warming and climate change. A promising solution to this is the System of Rice Intensification (SRI). Embraced in Vietnam's National Determined Contribution (NDC) under the Paris Agreement, SRI aims to boost rice yields while curbing greenhouse gas emissions compared to conventional farming practices. This study focuses on Thai Binh, a key rice-producing province in the Red River Delta. Our objective is to assess the economic, environmental, and broader societal impacts of SRI versus conventional farming. We conducted a comprehensive analysis, utilizing tools such as Cost and Benefit (CBA) evaluations, Marginal Abatement Cost (MAC) calculations, and the Linkert scale to gauge the effects. Data from 175 farmers in Phu Luong commune, Dong Hung district, Thai Binh province, formed the basis of our study. The results highlight the advantages of adopting SRI. Implementing SRI not only leads to a substantial increase of approximately 12 million Vietnamese Dong (VND) in revenue but also showcases a remarkably favorable cost of -2.7 VND for reducing 1 ton of CO2eq/ha during the transition from conventional farming. This highlights the financial and environmental benefits of SRI. Furthermore, our assessment demonstrates that SRI consistently outperforms conventional farming across economic, environmental, and societal dimensions. In essence, our findings strongly advocate for the adoption of SRI over conventional rice cultivation, as it not only mitigates environmental harm but also enhances farmers' profitability and well-being, aligning with sustainable agriculture practices and climate change mitigation efforts.

Development and validation of a questionnaire to assess owner and canine quality-of-life and treatment satisfaction in canine allergic dermatitis.

Animal and owner quality-of-life (QoL) is pivotal in treatment decisions. Accurate measurement of owner-reported QoL and treatment satisfaction (TS) supports disease burden and treatment benefit evaluation. Develop and evaluate an owner-completed canine dermatitis QoL and TS questionnaire (CDQoL-TSQ) in allergic dogs. The CDQoL-TSQ was drafted following review of existing measures and expert input. Content validity was assessed through interviews with owners of allergic dogs. Psychometric properties of the QoL domains (Canine QoL, Owner QoL) were evaluated. Score interpretation was derived. Twenty dog owners were interviewed. Item wording was amended following the first 10 interviews. Data from 211 owners were used in the psychometric evaluation. The Canine QoL domain demonstrated strong internal consistency (α = 0.89), test-retest reliability (ICC2,1 = 0.844), moderate convergent validity (r = 0.41) and moderate-high known-groups validity (effect size 0.37-0.64). The Owner QoL domain demonstrated strong internal consistency (α = 0.73), high convergent validity (r = 0.63) and moderate-high known-groups validity (0.43-0.63). Test-retest reliability approached moderate strength (ICC2,1 = 0.490). Group-level interpretation analysis showed minimal important difference of 7.0-13.6 points for dogs and 13.0-13.6 for owners. For individual dogs a change of 6.3 or 12.5 points for dogs, and 12.5 or 18.8 for owners indicates a response. The CDQOL-TSQ is a two-part assessment to evaluate QoL and TS in canine allergic dermatitis. The QoL questionnaire demonstrated validity and reliability, and interpretation of scores was derived, making it suitable for use in research and practice. The TS module is suitable for clinical setting use to improve owner-veterinarian communication.

THE BENEFIT EVALUATION FRAMEWORK OF USING PERFORMANCE-BASED CONTRACTING IN URBAN ROAD MAINTENANCE

Performance-based contracts (PBC) have been adopted increasingly in various countries. However, establishing an objective and convincing benefit evaluation framework to facilitate promotion remains a significant challenge for those who wish to use PBCs. A recent study introduced PBC in the context of daily inspection and repair of urban roads. The pilot program in that study successfully addressed the needs of road users, road maintenance authorities, and contractors. Consequently, this study develops the benefit evaluation framework for this type of PBC for broader applications. The proposed benefit evaluation framework, consisting of one qualitative and eight quantitative performanceevaluation items, calculates the effectiveness of introducing PBC to verify its practicality. The validation results show that qualitative benefit evaluation using the Pavement Condition Index achieves a “satisfactory” rating. For the quantitative benefit evaluation, an overall benefit-cost ratio (BCR) of 5.35 suggests that it is economically viable. The developed benefit evaluation framework can be used as a simple and easy-to-use evaluation tool for other organizations to assess whether to introduce PBC. This study fills this research gap by addressing the use of PBCs in the maintenance of all categories of toll-free roads, and contributes to expanding the application of PBCs in road maintenance services.

Economic Aspects of Prevention

Economic aspects of prevention refer to the costs and benefits associated with measures aimed at preventing various problems and risks. Prevention can include measures aimed at preventing disease, crime, harmful behavior, environmental problems and other areas. There are several important economic aspects of prevention: cost reduction, productivity gains, social and human benefits and long-term sustainability. It is important to realize that prevention requires initial investments and often its economic impact is not immediately visible. However, a long-term evaluation of costs and benefits shows that prevention can be an economically beneficial strategy that brings a large number of socioeconomic benefits for the individual and society as a whole.

500 - Patient-reported outcomes following 24 weeks of treatment with upadacitinib in adults with non-segmental vitiligo: results from a phase 2, randomized, double-blind, dose-ranging study

Abstract Introduction & Objectives Vitiligo has a considerable negative impact on patients’ health-related quality of life (HRQoL). Patients often experience social stigma, low self-esteem, anxiety, and depression. Assessment of HRQoL is therefore recommended as part of the evaluation of disease severity and treatment benefits. Accordingly, the impacts of treatment with upadacitinib (UPA), an oral Janus kinase inhibitor, on a range of patient-reported HRQoL outcomes were evaluated as part of a phase 2, multicenter, randomized, double-blind, placebo-controlled, dose-ranging study in adults with non-segmental vitiligo. Materials & Methods Adults aged 18–65 years with non-segmental vitiligo with a Facial Vitiligo Area Scoring Index score ≥0.5 and a Total Vitiligo Area Scoring Index score ≥5 at baseline were included in this 52-week study (NCT04927975). During a 24-week, double-blind, placebo-controlled treatment period (period 1), patients were randomly assigned to receive UPA 6 mg (UPA6), UPA 11 mg (UPA11), UPA 22 mg (UPA22), or placebo once daily (QD). Patient-reported HRQoL outcomes assessed at the week 24 primary analysis timepoint (ie, end of period 1) included change from baseline in vitiligo QoL (VitiQoL) total score (lower scores reflect better HRQoL), achievement of a Vitiligo Noticeability Scale (VNS) response of 4 (“a lot less noticeable”) or 5 (“no longer noticeable”), change from baseline in Dermatology Life Quality Index (DLQI; lower scores reflect better HRQoL), change from baseline in Hospital Anxiety and Depression Scale (HADS) anxiety and depression scores (where lower scores reflect less anxiety and/or depression), and achievement of a Patient’s Global Impression of Change-Vitiligo (PaGIC-V) response of 1 (“much better”) or 2 (“a little better”). Results A total of 185 patients were enrolled in the study (UPA6 n=49; UPA11, n=47; UPA22, n=43; placebo n=46). Mean reductions in VitiQoL scores from baseline to week 24 with UPA22 (−6.6) and UPA6 (−7.5) were numerically larger than with placebo (−5.5), although not statistically significant. At week 24, more patients treated with UPA22 reported a VNS response of “a lot less noticeable” or “no longer noticeable” than with placebo (11.6% vs 0%, respectively; P < .05). Mean reductions in DLQI scores from baseline to week 24 were significantly larger with UPA22 than with placebo (−2.2 vs −0.6; P < .05). HADS anxiety scores decreased from baseline to week 24 in the UPA6 and UPA22 groups, with similar reductions in HADS depression scores observed for the UPA11 and UPA22 groups; changes in HADS scores were not significantly different vs placebo. A significantly greater proportion of patients achieved a PaGIC-V response of “much better” or “a little better” with any UPA dose vs placebo: UPA6 (34.7%), UPA11 (55.3%), and UPA22 (60.5%) vs placebo (19.6%; P < .05 vs placebo for all UPA doses). Conclusion Among adults with non-segmental vitiligo, 24 weeks of treatment with UPA at all doses resulted in improvements compared to placebo in patient impressions of disease improvement based on PaGIC results. These initial findings suggest that UPA22 may improve patient HRQoL and perceptions of vitiligo noticeability; longer term data from the extension phase of this study will further clarify the impact of UPA treatment on QoL.

Optimization Analysis of an Energy-Saving Renovation Scheme for Building Envelopes of Existing Rural Houses Based on a Comprehensive Benefit Evaluation

In the cold regions of China, the existing rural houses are widely distributed and in large numbers. There are widespread problems such as low thermal performance of building envelopes, high building energy consumption, and poor indoor thermal environments. Reducing the energy consumption of building heating by reforming the envelope structure can reduce the environmental pollution caused by heating. In this paper, the existing rural houses in Tongchuan City, Shaanxi Province are taken as the research object, and EnergyPlus software is used to calculate building heating energy consumption, and the schemes are compared and selected via the entropy value method. Based on a comprehensive benefit evaluation, the best scheme for the renovation of building envelopes of rural houses in Tongchuan City is put forward. The research results show that the energy saving rate of buildings can reach more than 50% after renovation. In the evaluation of energy saving, incremental cost, return on investment, carbon emission reduction and unguaranteed hours, the weights are 0.1915, 0.2104, 0.2312, 1755, and 0.187, respectively. The best renovation scheme for rural housing is as follows: the thickness of the XPS board is 90 mm for exterior wall insulation; the thickness of the XPS board is 80 mm for roof insulation; the window-to-wall ratio of additional sunspace is 0.6; and the type of exterior windows is a broken-bridge hollow aluminum window of 6 + 12A + 6 (mm).

Утилитарная оценка пользы в бисубстантивных предложениях

The article describes the ways and means of expressing the evaluation of benefit in sentences that have two nouns in combination with a link in the predicative core. The place of utilitarian evaluation in the system of evaluative knowledge is determined. A scale of such evaluation "useful – harmless – indifferent – useless – harmful" is presented, and the identification of a neutral zone on it, formed by the value 'indifferent', is justified. The elements of the sentence with the utilitarian evaluation are identified, and the predominant representation of this evaluation in the link-substantive predicate is noted. The structure of the utilitarian evaluation of benefit in bisubstantive sentences is analyzed and described: the subject of evaluation, the subject of benefit or the subject of harm, the object of evaluation and the basis for evaluation, which coincides with the goal. The identification of the subject of harm is motivated. Productive grammatical means of expressing the utilitarian evaluation of benefit in bisubstantive sentences have been established. Cases of combining different subject types in this kind of sentences are characterized. Three groups of possible subjects of benefit were studied: a person (specific and abstract), a group of people (specific and abstract), animals as a special group in which the subjects of evaluation are always combined. The potential of utilitarian benefit evaluation compatibility with other types of evaluation is determined.

Impact of Date Powder, Sacha Inchi Oil, and Moringa Powder in a Novel Cognitive-Enhancing Health Bar: An Evaluation of Physicochemical Properties and Functional Benefits

Recent trends show a growing preference for healthy snacks in diets, particularly among health-conscious consumers, with snack bars gaining popularity among youth. This study aimed to develop and analyse a nutritious health bar to enhance cognitive performance. The health bar's formulation was created using design expert software. Comprehensive testing included proximate analysis, fatty acid profiling, and vitamin, mineral, and antioxidant evaluations, complemented by texture and colour assessments. Findings reveal these bars to be nutritionally rich, featuring excellent physical characteristics. They are notably abundant in essential fats (omega-3 and omega-6), vitamins, and minerals. The bars' high essential fat content, varied vitamin and mineral composition, and strong antioxidant properties align with the Recommended Nutrient Intakes (RNI) for Malaysian children and adolescents. This composition suggests that these health bars could effectively boost cognitive performance in this group.

Review of clinical outcomes of a cationic emulsion tear substitute in patients with dry eye disease.

First-line options for the treatment of dry eye disease (DED) rely on artificial tears (ATs), among which cationic emulsion (CE)-based ATs have been developed in order to mimic the healthy tear film for an improved restoration of the ocular surface homeostasis. In this review, we describe the outcomes reported in several studies, assessing the mode of action, ocular tolerance and clinical performance of a CE-based AT. Pilot studies have revealed that CE-based ATs can increase the volume and stability of the tear film while limiting its evaporation rate. Larger studies have demonstrated that CE-based ATs play a significant role in the improvement of both objective and subjective DED parameters, including superior efficacy on DED symptoms compared to several other available AT formulation types. Concomitantly, CE-based ATs have been shown to help patients to prevent or recover from corneal defects associated with refractive surgery. These positive outcomes on ocular surface epithelia are likely due to the combination of unique rheological behaviour and intrinsic anti-inflammatory properties. Based on all clinical findings, CE-based ATs represent a valuable treatment option for patients with various etiologies of DED including evaporative forms and would deserve evaluation of benefits in other surgical intervention types triggering DED.

Benefits evaluation of ecological restoration projects based on value realization of ecological products

Ecological restoration project is the premise to realize the value of ecological products. The current ecological product value accounting and ecological restoration project benefit evaluation methods are interlinked. The benefit evaluation of ecological restoration projects can not only analyze the completion of ecological restoration projects, but also quantify the impact of externalities on regional development. This study proposes a hypothesis that the benefit evaluation results of ecological restoration projects can affect the realization of urban ecological product value. In order to verify the above hypothesis, this study designed a benefit evaluation framework to evaluate the economic benefits, ecological benefits and project costs of ecological restoration projects. In this study, the benefit evaluation results are divided into three cases to calculate the benefit-cost ratio under different conditions. The three cases are only considering the direct economic benefits (DEB), considering the indirect economic benefits (TEB) and considering the comprehensive benefits (AEB). Taking Jiangyin City of Jiangsu Province as an example, the benefit evaluation of water source protection project in Jiangyin City is carried out. The results show that the benefit-cost ratios in the three cases are 6.68,7.60 and 9.36, respectively. The results show that the benefit-cost ratio is different in different benefit situations. Therefore, when discussing the realization path of ecological product value in ecological restoration areas, it is also necessary to discuss the situation. The evaluation system can provide reference for the benefit evaluation of ecological restoration projects, and also provide data and theoretical support for the realization of regional ecological product value.

Creative skills development: training translators to write in the era of AI

Developers of generative artificial intelligence systems promote the idea of personal assistants for various tasks, including translation and authoring creative content. As a consequence of these developments, the topic of “human” creativity has moved centre stage. Acknowledging similarities between translation and creative writing, this article offers a critical discussion of intersecting areas and suggests a framework for creative skills couched in the tradition of social sciences research. As a practical application with pedagogical impact, the paper presents a new module on writing specifically designed for translators. As is argued, the conceptual design, content, mode of delivery and evaluation of potential pedagogical benefits may be replicable in other pedagogical settings at undergraduate or postgraduate level. The role of technology is also problematised, indicating how writing may be augmented by using tools. Ideally, this is to be done in a context where creativity upskilling can equip students with the ability to (de)select context-appropriate solutions, that is, to use convergent and divergent thinking, ultimately preparing them to play a fundamental role in a rapidly evolving digital world.

Metal halide perovskite materials have shown significant advancements in their application as light absorbers in perovskite solar cells, with power conversion efficiencies reaching 27%. However, lead-based perovskites pose a concern due to their toxicity and stability issues in moisture, UV radiation, and heat. This has led to a pressing need to explore substitute materials that do not contain lead but maintain the remarkable characteristics of lead-based perovskites. This review article focuses on halide double perovskites characterised by the A2B’B”X6 composition, highlighting their structural, optical, thermoelectric, and mechanical capabilities. Additionally, the review evaluates several materials databases to investigate materials suitable for high-throughput first-principles calculations integrated inside density functional theory. The review aims to identify novel perovskite materials, offer a thorough evaluation of the potential benefits and drawbacks associated with this class of materials, and, from the pedagogical standpoint, discover effective instructional frameworks.

Abdominal Wall Hernias-State of the Art of Laparoscopic versus Robotic Surgery.

Abdominal wall hernia repair, a common surgical procedure, includes various techniques to minimize postoperative complications and enhance outcomes. This review focuses on the comparison between laparoscopic and robotic approaches in treating inguinal and ventral hernias, presenting the ongoing situation of this topic. A systematic search identified relevant studies comparing laparoscopic and robotic approaches for inguinal and ventral hernias. Randomized control trials, retrospective, and prospective studies published after 1 January 2000, were included. Search terms such as hernia, inguinal, ventral, laparoscopy, robotic, and surgery were used. A total of 23 articles were included for analysis. Results indicated similar short-term outcomes for robotic and laparoscopic techniques in inguinal hernia repair, with robotic groups experiencing less postoperative pain. However, longer operative times and higher costs were associated with robotic repair. Robotic ventral hernia repair demonstrated potential benefits, including shorter hospital stay, lower recurrence and lower reoperation rates. While robotic surgery offers advantages such as shorter hospital stays, faster recovery, and less postoperative pain, challenges including costs and training requirements need consideration. The choice between laparoscopic and robotic approaches for abdominal wall hernias should be tailored based on individual surgeon expertise and resource availability, emphasizing a balanced evaluation of benefits and challenges.

Separation and enrichment of tricolor phosphors in waste phosphors through liquid–liquid–powder extraction method and its benefit evaluation for recovery

This study aimed to separate and enrich tricolor phosphors powder including red, blue, and green phosphors in waste phosphors which also contained white phosphors through liquid–liquid–powder extraction method. Kerosene and water were used as the two liquids. Dodecylamine acetate (DAA) was used as the surfactant collector. The operating factors including pH, DAA dosage, kerosene–water volume ratio, solid concentration, extraction temperature, and extraction time, on the enrichment of tricolor phosphors powder were investigated. In addition, the benefit of introducing liquid–liquid–powder extraction method in the recovery procedure of tricolor phosphors from waste phosphors was also evaluated through the comparison of applying hydrochloric acid (HCl) leaching for the separated tricolor phosphors and the waste phosphors.The results indicated that the optimal conditions of liquid–liquid–powder extraction method were that the dosage of DAA was 1.5 kg/ton at pH 3 with a kerosene–water volume ratio of 20/80 (v/v), a solid concentration of 1.25 w/v%, an extraction temperature of 25 °C, and an extraction time of 15 mins. Under these conditions, the grade of tricolor phosphors recovered from the water phase was enriched from its initial grade of 15.0 % in the waste phosphors to 72.5 % with a recovery of 67.4 %. The benefit of introducing liquid–liquid–powder extraction method was that more than 50 % of the reagent cost and nearly 90 % of the wastewater generation were reduced compared to those without liquid–liquid–powder extraction treatment. In addition, white phosphors with a grade of 92.3 % and a recovery of 96.7 % could be recovered from the kerosene phase simultaneously. This study also demonstrates the merit of introducing a physical separation treatment in a resources recovery procedure before chemical treatment.

Benefit Evaluation of Carbon Reduction and Loss Reduction under a Coordinated Transportation–Electricity Network

With the extensive promotion of new energy vehicles, the number of electric vehicles (EVs) in China has increased rapidly. Electric vehicles are densely parked in garages, which means parking garages contain a large amount of idle energy storage resources. How to make this idle energy storage in garages participate in power system dispatch and evaluate the network loss and system carbon emissions considering electric vehicle energy storage has become an important research topic. The uncertainty around parking habits for electric vehicles causes it to be difficult to predict compared with the traditional energy storage system. Therefore, it is necessary to study its influence on the synergistic effect of loss reduction and carbon reduction as energy storage access. The benefits of new energy power generation output growth, energy waste reduction, and carbon emission reduction brought by loss reduction measures can be well reflected in the loss reduction index system of a power system in a low-carbon scenario. In this paper, a large amount of parking information in a certain area is collected, and the approximate parking habits of all vehicles in the simulated garage are obtained by the Monte Carlo method. Then, the load aggregation model is established, which is incorporated into the power system as an energy storage model. The synergy of loss reduction and carbon reduction is considered in this paper and comprehensively optimizes the strategy of integrating electric vehicles into the power system from the perspectives of electricity and carbon. In the scenarios of carbon flow calculation and network loss calculation, the YALMIP and CPLEX of MATLAB are applied, with various constraints input for simulation, so that the benefit evaluation method of carbon reduction and loss reduction under a coordinated transportation–electricity network is obtained.

Managing BEV Charge to Obtain a Positive Impact on a National Power System

This paper’s research question is to evaluate the potential impact of large numbers of battery electric vehicles (BEVs) on the future electric grid, and whether the flexibility of BEV charging can induce enough system benefits to remunerate BEV users for the change in their recharging pattern. The considered scenario refers to the Italian situation and what might occur through the year 2040, where a share of BEV stock of 40% can be foreseen, as well as significant increases in PV and wind generation. Although this study is focused on Italy, its results are applicable, with minor differences, to several EU countries. This paper first shows that the future impact of increasing penetration of BEVs appears to be compatible with the expected growth of generation from renewable energy sources (RES) and the corresponding reduction in fossil fuel-based generation. It also gives an estimate of the CO2 emission reduction resulting from these changes, considering an unmanaged BEV charge profile and two different managed profiles that shift the car’s charging period to hours of the day when they have no negative impact on the grid and maximize the utilization of RES. Finally, it shows an evaluation of the economic benefits of displacing private car charging ranging from 4 to 10 cEUR/kWh, which could be used as tariff incentives to stimulate this displacing in recharging time.

Optimization of Carbon Sequestration and Carbon Displacement in Fractured Horizontal Wells in Low Permeability Reservoirs

The increasing use of fossil fuels has raised concerns about rising greenhouse gas emissions. Carbon capture, utilization, and storage (CCUS) is one of the most important technologies for achieving net zero carbon emissions. In oil reservoirs, fully understanding their geological characteristics, fluid characteristics, and pressure distribution and injecting CO2 in a reasonable scheme, some remaining oil can be recovered to improve oil recovery and even obtain certain economic benefits. In this paper, we investigate the effect of CCUS implementation in low-permeability reservoirs from both technical and economic aspects. First, based on the parameters of a low-permeability reservoir, a numerical simulation model of a reservoir with gas injection in a multi-stage fractured horizontal well at the top of the reservoir and oil recovery in a multi-stage fractured horizontal well at the bottom is established. Next, four cases of continuous CO2 injection, intermittent CO2 injection, CO2 injection after water flooding, and water alternating gas drive (WAG) are designed to evaluate their effects on CO2 storage and enhanced oil recovery. Finally, an economic evaluation model is developed to evaluate these four cases. The results show that fractured horizontal wells can improve the injection capacity, increase the swept volume of injected gas, cause CO2 to fully contact the crude oil, greatly increase the contact area between the wellbore and crude oil, and greatly improve oil recovery. The WAG injection-production method can effectively inhibit gas channeling, reduce the production gas–oil ratio, improve oil recovery, and, at the same time, bury more CO2 into the reservoir. Its economic benefit evaluation is also the best among the four cases. In addition, the remaining oil distribution and CO2 buried distribution under different injection-production schemes are also analyzed. This study provides a scientific basis for the operation scheme design of CCUS in low-permeability reservoirs.

Evaluation of net carbon sequestration and ecological benefits from single biochar-incorporated sorghum farmland systems in saline-alkali areas of Inner Mongolia, China

Biochar is widely recognized as a soil amendment to reduce greenhouse gas emissions and enhance soil carbon storage in agroecosystems; however, the systematic focus on carbon balance and ecological benefits in cropping systems remains unclear in saline-alkali areas under water-saving irrigation. Here, a 2-yr field experiment with carbon footprint method was conducted to determine soil carbon budgets, biochar carbon efficiency performance, and the economic and ecological benefits of mulched drip-irrigated sorghum production, in an arid salinized region of Inner Mongolia, China. Corn straw-derived biochar dosages of 0 (CK), 15 (B15), 30 (B30), and 45 (B45) t hm−2 were just applied into the soil in the first crop growing season. A single application of biochar to soil significantly reduced CO2 emissions for the current and subsequent crop-growing seasons, with 13.1%, 16.7%, and 12.5% reductions for B15, B30, and B45, respectively. Compared with the non-biochar control plots, B15, B30, and B45 also increased NPP by 36.7%, 38.4%, and 27.1%, respectively. The actual effects on improving net carbon sequestration for B15, B30, and B45 in the first year were higher than those in the second year, with mean increases of 1.27, 1.47, and 1.36 times, respectively; however, the efficiencies of biochar for fixing carbon per biochar dosage input for B15 were 72.8% and 64.1% higher than those of B30 and B45, respectively. Net profits were significantly improved by 57.2–87.1% by biochar treatments. The environmental benefits of biochar carbon trading revenues for B15, B30, and B45 increased by 105.9%, 162.1%, and 109.6%, respectively. The minimum observation for carbon productivity and the maximum measurements for both the economic and ecological benefits were B15. The B15 also significantly increased sorghum yield and grain number. Results demonstrate that biochar application in the current growing season helps reduce soil carbon emissions, increases net carbon sequestration for current and subsequent sorghum agroecosystems, and enhances net profit and ecological benefits. The optimal positive synergistic effect was observed at a biochar application rate of 15 t hm−2 for reducing soil carbon emissions, increasing crop production, and improving the ecological environment.
