While green infrastructures (GIs) are used to address urban flooding and stormwater runoff and enhance sustainability, their implementation faces challenges such as limited funding and competing priorities. Existing studies generally focused on specific/individual GI practices, potentially overlooking the broader benefits or values of comprehensive GI plans that generally are interconnected networks of multiple GI practices. Thus, this paper developed an agent-based model to offer municipalities, planners, and decision makers a structured and systematic modeling approach to: (1) simulate the dynamic nature of GI implementation plans across spatial and temporal dimensions; (2) capture the interplay among regulations that govern GI plans; and (3) conduct scenario and sensitivity analyses to gain deeper insights into the various characteristics of GI plans under different scenarios. The proposed model considered different economic values of GI plans, including stormwater management, carbon sequestration, pollutant removal, energy cost savings, and increased property value, as well as the social values, such as the positive impact on nearby residents/communities. In addition, the developed model considered the following six GI practices: green roofs, rain gardens, community gardens, bioswales, permeable playgrounds, and permeable pavements. These GI practices were modeled across five submodels: school greening, private property greening, park greening, right-of-way property greening, and public housing properties greening. Scenario analysis was conducted to investigate the effect of financial limitations (i.e., funding priorities) on the model's behavior under two scenarios. Finally, the developed model was statistically validated. The results showed that increasing the number of GIs does not guarantee an increase in their economic value, but rather the implementation of GIs should be well planned according to a priority plan. The findings also provided valuable insights into the importance of considering physical and institutional limitations. This paper contributes a practical workflow for evaluating the costs and benefits of GI programs. [ABSTRACT FROM AUTHOR]

Introduction: Prosopis juliflora has posed a severe threat to human and animal life in arid and semi-arid areas of the world. Thus, this review intends to shed light on the potential use of Prosopis as a helpful resource and feasible management system. Methods: This research employs a systematic review methodology. Results: The review revealed that the species had been introduced to overcome deforestation and desertification. Prosopis juliflora has had different socioeconomic and environmental impacts on local communities. The most widely cited adverse impacts include out-competing native species and quickly reducing forage plants, being a harbour for predators, health problems and death of domestic animals, and being an ideal ground for mosquito breeding. On the other hand, the species provides multiple ecosystem services like the provision of construction materials, animal feed and charcoal; plays a role in soil conservation and rehabilitation of degraded and saline soils, good sources of nectar for honey production; contributes to reducing dust pollution; enhances carbon sequestration, and have medicinal value due to its antifungal and antibacterial features. The local community's attitude regarding the species is mixed. Discussion: The consequent negative impacts are increasing quickly, making the urgent need to develop robust and practical management strategies necessary to both mitigate the adverse effects and fully use the benefits. Commercialization (with a notion of management through utilization) is a feasible way to minimize expansion. Cross-boundary endeavours for controlling Prosopis juliflora expansion to new regions, particularly in countries predicted as edges of high potential invasion, are required to manage the species invasion efficiently.

[Objective] To study the effects of mung bean and millet rotation on yield, economic benefits and soil physicochemical properties under fallow land conditions. [Method] Using different varieties of summer millet and mung beans as materials, a two crop planting experiment was conducted once a year. The growth period, agronomic traits, yield related traits and soil physicochemical traits of mung beans and millet at maturity were recorded and analyzed. [Result] The growth duration of early sowing of mung beans (T1, T2, T3 treatments) was lower than that of the control, shortened by 6, 10 and 12 days, respectively. The growth duration of late sowing of millet (Y1, Y2, Y3 treatments) was shorter or equal to that of the control. In the annual two crop planting mode of mung beans and foxtail millet, the rotation mode T2Y2 treatment (Jilv 19+Jigu 45) was better. Under this mode, the yield of mung beans was 2 286.0 kg/hm², and the yield of foxtail millet was 2 431.5 kg/hm², with an annual income of about 30 441.0 yuan/hm², which was higher than the control millet (conventional time sowing) of 6 924.0 yuan/hm². After maturity, the content of NH4+and NO3- in the soil decreased compared to before planting, and the content of NO3- reached a significant difference. The yield and economic benefits of mung beans were significantly correlated with growth duration, single pod weight, single grain weight, plant height and dry weight. The single pod weight and single grain weight of mung beans were significantly positively correlated with their yield, and were significantly negatively correlated with growth duration, plant height and dry weight. The yield of foxtail millet was significantly positively correlated with growth duration, single spike weight, single spike grain weight and grain yield. [Conclusion]Mung beans were suitable for sowing in early May, while millet was suitable for sowing in early July, and should not exceed August, which increased income, facilitated the integration of land use and nutrients, and promoted sustainable land use.

Decarbonizing heat-intensive industries by reusing the waste heat for power or combined heat and power systems is becoming increasingly important to address global warming. The Organic Rankine Cycle has shown a high level of feasibility and performed efficiently for utilizing medium-to-low-grade heat from renewable resources and heat-intensive industries for direct power generation. This study contributes to the field by conducting a techno-economic investigation of various Organic Rankine Cycle configurations to enhance energy conversion when real-life transient waste heat sources are available. These configurations were optimized to maximize energy output along with economic benefits. The non-linear programming by quadratic Lagrangian, a computational unintensive yet accurate optimization algorithm, was utilized for the multi-objective optimization. The optimized cycle configurations showed a 12.57% enhancement of turbine efficiency. Combining regeneration and recuperation enhanced the superheating by 32%, and the optimized air preheater cycle improved the overall objective by 64.2% compared to the pre-optimized conventional cycle, leading to a feasible 1.72-year payback period.

Vegetables are important economic crops globally, and their production has approximately doubled over the past 20 years. Globally, vegetables account for 13% of the harvested area but consume 25% of the fertilizer, leading to serious environmental impacts. However, the quantitative evaluation of vegetable production systems in subtropical plateau lake basins and the establishment of optimal management practices to further reduce environmental risks are still lacking. Using the life cycle assessment method, this study quantified the global warming, eutrophication, acidification, and energy depletion potential of vegetable production in a subtropical plateau lake basin in China based on data from 183 farmer surveys. Our results indicated that vegetable production in the study area, the Erhai Lake Basin, was high but came at a high environmental cost, mainly due to low fertilizer efficiency and high nutrient loss. Root vegetables have relatively high environmental costs due to the significant environmental impacts of fertilizer production, transportation, and application. A comprehensive analysis showed that the vegetable production in this region exhibited low economic and net ecosystem economic benefits, with ranges of 7.88–8.91 × 103 and 7.35–8.69 × 103 $ ha−1, respectively. Scenario analysis showed that adopting strategies that comprehensively consider soil, crop, and nutrient conditions for vegetable production can reduce environmental costs (with reductions in global warming potential (GWP), eutrophication potential (EP), acidification potential (AP), and energy depletion potential (EDP) by 10.6–28.2%, 65.1–73.5%, 64.5–71.9%, 47.8–70.4%, respectively) compared with the current practices of farmers. This study highlighted the importance of optimizing nutrient management in vegetable production based on farmers' practices, which can achieve more yield with less environmental impacts and thereby avoid the "trade-off" effect between productivity and environmental sustainability.

Forests are complex ecosystems that require integrated management to balance economic, social, and environmental dimensions. Conflicting objectives among stakeholders make optimal decision-making particularly challenging. This study seeks to balance the economic gains of forest harvesting with the goals of environmental conservation, with a focus on the Shafarood forest in Northern Iran. We applied multi-objective optimization and game theory to maximize the net present value (NPV) of forest harvesting while enhancing carbon sequestration. The research utilized data on stumpage prices, harvesting costs, tree density, volume per ha, growth rates, interest rates, carbon sequestration, and labour costs. Applying the epsilon-constraint method, we derived Pareto optimal solutions for a bi-objective model, and game theory was applied to negotiate between economic and environmental stakeholders. In the fifth round of bargaining, a Nash equilibrium was achieved between the two players. At this equilibrium point, the economic player achieved NPV from forest harvesting of 9001.884 (IRR 10,000/ha) and amount of carbon sequestration of 159.9383 tons/ha. Meanwhile, the environmental player achieved NPV from forest harvesting of 7861.248 (IRR 10,000/ha), along with a carbon sequestration of 159.9731 tons/ha. Results indicate significant trade-offs but reveal potential gains for both economic and environmental goals. These findings provide a robust framework for sustainable forest management and offer practical tools to support informed decision-making for diverse stakeholders. [ABSTRACT FROM AUTHOR]

This paper explores the impact of different charging pile business models on their economic and environmental benefits. Firstly, this paper analyzes the cooperation and competition relationships among the stakeholders under three charging pile business models, and their impact on the whole process of charging pile from design, production, operation to recycling. Secondly, this paper establishes a social economic benefit evaluation model and a life cycle carbon emission evaluation model based on the differences of charging pile in quality, cost, life span and high-value component recycling rate under different business models. Finally, this paper conducts a case analysis of the economic and environmental benefits of three business models combined with China's actual situation. The research results show that the economic and environmental benefits of each party in the three business models are closely related to the quality, cost, life span and high-value component recycling rate of the charging pile. Among them, the life span of the charging pile has the greatest impact on its economic and environmental benefits. The higher the recycling rate of high-value components, the more conducive to improving its economic and environmental benefits. The research results will provide reference for policy makers and EVCI investors. [ABSTRACT FROM AUTHOR]

Aquavoltaics is an innovative and beneficial solution that makes dual use of water area for photovoltaic (PV) power generation and aquaculture. Currently, China has made remarkable developments in aquavoltaics. This paper first analyzes the current development status of aquavoltaics in China, then takes the TW "fishery–PV integration" base project in Nanjing, Jiangsu Province, as a case study to analyze its economic and social benefits, and finally puts forward countermeasure suggestions for the development of aquavoltaics in China. It is found that Jiangsu Province is one of the clustering areas for the development of aquavoltaics in China, and the development of aquavoltaics in this province has a high level of specialization. The payback period (PP) of the TW "fishery–PV integration" base project is 10.44 years, the net present value (NPV) is USD 18.5334 million (the discount rate is 5%), and the internal rate of return (IRR) is 8.06%. The social benefits of this project are mainly reflected in the promotion of energy conservation and emission reduction, the alleviation of energy shortages, the optimization of land use, and the development of culture, tourism, science, and education. The development of aquavoltaics should be promoted by strengthening scientific research, paying attention to the impact of PV panel erection on the ecological environment of the waters, emphasizing the fishery farming part of the aquavoltaic project, and improving the commercial operation mode of the aquavoltaic project.

This study investigates the economic and ecological impacts of straw returning technology among apple growers in Shaanxi and Gansu provinces, China. Using Propensity Score Matching (PSM) and survey data, the findings reveal that straw returning significantly increases farmers' incomes by 20.33% compared to those who do not adopt the technology. Additionally, the technology mitigates soil fertility decline by 11.07%, offering substantial ecological benefits. The heterogeneity analysis highlights that older farmers benefit more from the technology in terms of both income and soil fertility improvement, likely due to their experience and reliance on farming. Smaller-scale farmers also show greater gains in income and soil health, while larger-scale farms face complexities that may delay visible benefits. However, land fragmentation did not significantly influence the outcomes. The study recommends promoting straw returning through enhanced farmer training, financial incentives, and improved access to credit. Policymakers should consider tailoring support to different farmer demographics and orchard sizes. Future research should focus on long-term evaluations of straw returning's sustainability in terms of soil fertility and crop yields. Overall, straw returning technology offers a promising solution for enhancing both economic returns and environmental sustainability in apple production. [ABSTRACT FROM AUTHOR]

The study indicates that adding 20 g/(head·d) of oregano essential oil to beef cattle feed has the better growth performance and breeding economic benefits. [ABSTRACT FROM AUTHOR]

Migration plays a crucial role in shaping destination countries' social and economic landscapes, including in Ecuador. This study aims to explore the benefits and challenges of migration by analyzing the perceptions of Ecuadorians who have directly or indirectly encountered its effects. Using a mixed-methods approach, we surveyed 1048 Ecuadorians and conducted 27 in-depth interviews to capture various viewpoints. The findings reveal a complex perspective: 47% of respondents view migration positively, emphasizing economic opportunities and cultural enrichment, while 53% express concerns about issues such as employment mismatches and barriers to social integration. These insights highlight the need for further research, e.g., to explore tailored policy solutions and deepen the understanding of migration's multifaceted impact on Ecuador's society and economy. The results highlight the need to investigate how media perceptions of migration influence the attitudes and decisions of migrants and host communities to design more balanced and realistic information campaigns for informed decision-making.

The experiment aims to investigate the effects of crude extracts of Codonopsis pilosula and As‐ tragalus membranaceus on the production performance, intestinal health, and economic benefits of Longlin black pigs. A total of 108 190-day-old Longlin black pigs were randomly divided into three groups. The control group (CON group) was fed with a basic diet. Experiment group 1 (group T1) and experiment group 2 (group T2) were supplemented with 3.5 and 7.0 g/kg of Codonopsis pilosula and Astragalus mem‐ branaceus crude extracts on the basic diet, respectively. The experimental period was 30 days. The results showed that compared with the CON group, the final weight and average daily weight gain in group T2 increased significantly(P<0.05), while the feed to weight ratio decreased significantly (P<0.05). The verage daily weight gain increased slightly, and feed to weight ratio increased slightly in group T1, but the difference was not significant (P>0.05). Compared with the CON group, the duodenal villus height and crypt depth in the group T2 were significantly increased (P<0.05), while there was no significant difference in duodenal villus height in the group T1(P>0.05). Compared with the CON group, at the phylum level, there was no significant difference in the relative abundance of Firmicutes, Bacteroidetes, and Spirochetes in the group T2 (P>0.05). At the genus level, the relative abundance of Lactobacillus genus and Rikenellaceae RC9_gut_group in the group T2 significantly increased (P<0.05). Compared with the CON group, the feed cost of T1 group and T2 group increased by 6.37% and 12.70%, respectively. The breeding profits increased by 2.19% and 3.67% respectively. In summary, adding Co‐donopsis pilosula and Astragalus membranaceus crude extracts to the diet has a certain positive effect on the production performance, intestinal health, and economic benefits of Guangxi Longlin black pigs; and the application effect of adding 7.0 g/kg was better.

This study examines the financial costs and savings of a community-based intergenerational volunteer program (i.e. Snow-buddies) that pairs youth with older adults for snow removal. From March 2020 to May 2023, Snow-buddies completed 106 volunteer-matches and 486 snow removal events. Using a sequential exploratory mixed-method design, 14 semi-structured interviews were conducted with youth volunteers and older adults. The majority of participants revealed minimal out-of-pocket (OOP) expenses and time/productivity losses for snow removal. Increased mobility, fall prevention, and social connections were perceived benefits of the program. A survey (n = 55, 52% of matched participants) reported an average CAD$123 OOP spending per snow removal event. Applying the rate of fall injuries among older adults due to snow, an estimated 1.12 fall injuries per 486 person-events were prevented translating into a total of $81,398 financial savings from averted hospitalization (i.e. a benefit–cost ratio of ~$662 for every dollar spent on snow removal).

[Introduction] Under the "dual carbon" goal, energy storage has become an important participant in regulating the electricity market and a key link in building a new type of power system. Under the current energy storage market conditions in China, analyzing the application scenarios, business models, and economic benefits of energy storage is conductive to provide a fundamental basis for the future large-scale development and commercial operation of new energy storage. [Method] The paper studied the application scenarios of energy storage on the power generation side, grid side, and user side, analyzed the economic benefits and income sources of various types including power generation side, independent shared energy storage, etc., summarized the problems in the initial development of energy storage, and proposed relevant suggestions. [Result] Currently, the cost per kilowatt-hour for novel electrochemical energy storage in China is relatively high, leading to low overall economic benefits. Investment entities find it difficult to achieve profitability, and there are limited business models available. [Conclusion] In the future, China should establish diverse revenue sources for new energy storage, support various market entities in investing in, constructing, and operating shared energy storage facilities, and innovate market profit models for the development of new energy storage.

There are many ships and ports in Shanghai coastal zones, where disastrous weather occurs frequently. Meteorological disasters often threaten the safety of people’s lives and properties along the coast and in the ports. In the past, the meteorological warnings for Shanghai coastal zones are mainly based on those issued for Yangshan Port by Shanghai Marine Meteorological Centre (SMMC), which are called “unified warnings”. However, there are obvious differences in the time and intensity of meteorological disasters in each region, and the unified warnings cannot meet the needs of the production and operation of the shipping and ports. In 2020, Shanghai coastal zones were divided into five sub-zones, where the meteorological forecast and warnings were carried out separately from July 2020. Based on hourly observational data of the representative stations in Shanghai coastal zones and warning signal data from 2016 to 2022, the gale events are selected to analyse the statistical characteristics of temporal and spatial distribution and evaluate the forecast quality and the economic benefits of the zonal warnings. The results show that: (1) The farther away from the coastline, the more gale days, the higher the wind speed and the longer the duration; the higher the wind speed during the process, the more obvious the difference of wind scale. In particular, the wind scale caused by typhoons can range up to 5 levels. (2) Compared with the “unified warning”, the missing alarm rate (MAR) of gale warnings in each sea area has been reduced significantly, by up to 5%, the false alarm rate (FAR) for the western part of Yangtze River estuary is reduced by more than 8% and the TS score is significantly improved by more than 10%. (3) The advance time of gale warnings has been reduced by more than 3 hours, the maintaining duration has been shortened by more than 16 hours at most, which can reduce the loss of nearly 18 million RMB and improve the production efficiency of the coastal zones of Shanghai greatly. The results of this paper show that refined marine meteorological forecasts and early warnings provide a safety guarantee for marine transportation and port production operations, resulting in significant social and economic benefits and the enhancement of the comprehensive guarantee level of marine meteorological services in Shanghai. In the next step, we will continue to research and develop more refined objective forecast methods adapted to this business, then build a regional shared operational system platform and extend it to the Yangtze River Delta region, so as to promote the high-quality development of shipping meteorological integration in the Yangtze River Delta region.

• Combining slow-release fertilizer with plastic film mulching (PM-S) significantly increased spring maize yield and economic benefit. • PM-S produced the highest soil carbon sequestration rate. • Nitrogen fertilizer was the primary contributor to total greenhouse gas emissions. • PM-S significantly decreased net greenhouse gas emissions, carbon footprint, and carbon footprint per net return. Agricultural practices significantly contribute to greenhouse gas (GHG) emissions, necessitating cleaner production technologies to reduce environmental pressure and achieve sustainable maize production. Plastic film mulching is commonly used in the Loess Plateau region. Incorporating slow-release fertilizers as a replacement for urea within this practice can reduce nitrogen losses and enhance crop productivity. Combining these techniques represents a novel agricultural approach in semi-arid areas. However, the impact of this integration on soil carbon storage (SOC S), carbon footprint (CF), and economic benefits has received limited research attention. Therefore, we conducted an eight-year study (2015–2022) in the semi-arid northwestern region to quantify the effects of four treatments [urea supplied without plastic film mulching (CK-U), slow-release fertilizer supplied without plastic film mulching (CK-S), urea supplied with plastic film mulching (PM-U), and slow-release fertilizer supplied with plastic film mulching (PM-S)] on soil fertility, economic and environmental benefits. The results revealed that nitrogen fertilizer was the primary contributor to total GHG emissions (≥71.97%). Compared to other treatments, PM-S increased average grain yield by 12.01%–37.89%, water use efficiency by 9.19%–23.33%, nitrogen accumulation by 27.07%–66.19%, and net return by 6.21%–29.57%. Furthermore, PM-S decreased CF by 12.87%–44.31% and CF per net return by 14.25%–41.16%. After eight years, PM-S increased SOC S (0–40 cm) by 2.46%, while PM-U decreased it by 7.09%. These findings highlight the positive effects of PM-S on surface soil fertility, economic gains, and environmental benefits in spring maize production on the Loess Plateau, underscoring its potential for widespread adoption and application.

The urgent need for sustainable waste management has led to the exploration of upcycling waste plastics and biomass as viable solutions. In 2018, global plastic production reached 359 million tonnes, with an estimated 12000 million tonnes projected to be delivered and disposed of in landfills by 2050. Unfortunately, current waste management practices result in only 19.5% of plastics being recycled, while the rest is either landfilled (55%) or incinerated (25.5%). The improper disposal of plastics contributes to issues such as soil and groundwater contamination, air pollution, and wildlife disturbance. On the other hand, biomass has the potential to deliver around 240 exajoules of energy per year by 2060. However, its current utilization remains relatively small, with only approximately 9% of biomass-derived energy being consumed in Europe in 2017. This review explores various upcycling methods for waste plastics and biomass, including mechanical, chemical, biological, and thermal approaches. It also highlights the applications of upcycled plastics and biomass in sectors such as construction, packaging, energy generation, and chemicals. The environmental and economic benefits of upcycling are emphasized, including the reduction of plastic pollution, preservation of natural resources, carbon footprint reduction, and circular economy advancement.

The study aims to quantitatively assess the availability of various infrastructures for doing business and identify the main barriers in the infrastructure industry that hinder the ease of doing business and investment development in regions of Kazakhstan. The authors assessed infrastructure accessibility in Kazakhstan's regions based on an SME managers' survey. They developed an index of infrastructure availability, a practical tool for gauging infrastructure development in a specific region or country. This index is crucial for investment planning and developing relevant sectors of the national economy. The findings revealed that no region in Kazakhstan has a good infrastructure. Access to its most essential types is only at an average level, with the lowest index values observed in Almaty and East Kazakhstan regions. The analysis of SMEs' problems with access to infrastructure highlighted bureaucracy and difficulties in obtaining permits, high wear and tear of networks, and high connection costs as the main issues. The authors underscore the increasing global economic and geopolitical risks that lead to fundamental changes in Central Asia, particularly Kazakhstan, which has excellent potential for developing transit routes between East and West. They advocate for active investment in infrastructure projects as a solution. According to expert forecasts, if Kazakhstan invests at least 4% of its GDP annually, it can completely replace and modernize the republic's worn-out transport infrastructure by 2040, leading to significant economic benefits. The authors will use the study's results to create regional indices of doing business in Kazakhstan.

The commercialization of scientific research and development (R&D) results is a key driver for enhancing corporate revenues and profits, positively impacting economic development, and increasing global and national competitiveness. However, commercialization is a complex process influenced by various factors. This study aims to assess the mutual influence of commercialization factors of R&D in Kazakhstan and provide recommendations to strengthen positive influences and mitigate negative ones. Utilizing official data from the Bureau of National Statistics, including metrics such as enterprise innovation activity, the share of innovative products in GDP, patent numbers, R&D expenditures, industry innovation costs, and R&D personnel, a regression analysis was conducted using the time series method and the vector autoregression (VAR) approach. The analysis revealed that increased innovative activity of enterprises positively impacts the export of innovative products after three years but negatively affects the share of innovative products in GDP. Additionally, higher industry innovation costs and an increase in patent numbers lead to a rise in innovative product exports after three years. However, an increase in innovative product exports subsequently reduces patent numbers after three years. These results indicate that domestic enterprises focus primarily on expanding export-oriented products for short-term profit gains, reducing costs, and achieving immediate results, often at the expense of substantial innovation activities. The findings suggest a need for strategies to balance short-term profit motives with sustainable innovation investments to enhance long-term economic growth and competitiveness.

Timber industries make an essential contribution to economies worldwide, while the sustainable supply of timber generates revenue, supports employment, and contributes to economic activity. The strategic choice of wood species using specific criteria can have substantial economic outcomes for the timber industry in Greece. This study assessed the suitability of hardwood species most commonly used by Greek timber industries. The assessment was conducted with the use of a Multiple-Criteria Decision Analysis approach, taking into consideration specific criteria that affect the quality of timber. According to the findings, walnut was the optimal alternative that outranked the other examined species. Chestnut, oak, beech, ash, and hornbeam also achieved positive scores, and therefore, they are also acceptable alternatives as broadleaved species suitable for furniture manufacturing and sawn timber production. Greek timber industries can enhance their products’ value and market appeal by focusing on species that meet high-quality standards and consumer preferences.

Owing to the generation of waste during mining and processing, granite stone causes great damage to the environment. In this study, the broken granite waste and the stone powder were used as concrete coarse aggregate and “admixture” to make granite waste concrete hollow blocks, which could meet the requirements of compressive strength, durability and economy. The influence of the water-binder ratio, cement dosage, and powder-slag ratio on the compressive strength and freeze-thaw properties of the block were analyzed. Subsequently, the optimal mix ratio was determined based on range analysis. The effect of granite waste on the compressive strength and durability of the blocks was also analyzed. In addition, the economic effects of the granite waste concrete hollow block were analyzed. The results show that granite waste concrete hollow blocks with a water-binder ratio of 0.55, powder slag ratio of 15%, and cement dosages of 340 kg/m3 and 320 kg/m3 can meet the strength requirements of MU10 grade and the requirements of freeze-thaw properties. The strength and frost resistance of the granite concrete hollow blocks were enhanced because the granite powder filled the aggregate gaps. In addition, the price of granite concrete hollow blocks was reduced by approximately 50%. The small hollow block of granite concrete is environmentally friendly and worth promoting.

Using Zuoshi No.1, one of the main potato varieties cultivated in Enping City, Guangdong Province, as the material, a randomized block design was used to study the effects of organic-inorganic compound fertilizer on potato yield, quality, etc. The aim was to provide theoretical basis for the rational use of organic-inorganic compound fertilizer in winter potato production in this area. The results showed that T3 treatment had significant yield increasing benefits, could ensure the quality of potato tubers, had the highest commercial potato rate, and the highest economic benefits; and the partial productivity (119.84 kg/kg) and agronomic efficiency (67.10 kg/kg) of this treatment were both the highest. Taking into account potato yield, quality, fertilizer utilization rate, and economic benefits, it is recommended that 900 kg/hm² of organic-inorganic compound fertilizer be applied as a suitable fertilization scheme for winter potato production.

The experiment aimed to explore the effects of adding different amounts of fermented cassava residue to the feed on the growth performance, serum biochemical indexes, and economic benefits of Hu sheep. A total of 48 weaned Hu sheep were randomly divided into four groups, with 12 replicates per group and one sheep per replicate. The sheep in each group were fed with feed containing 0 (control group), 10%, 20%, and 30% fermented cassava residue. The preliminary trial period was seven days, and the formal experimental period was 60 days. The results showed that compared to the control group, the final weight, total weight gain, and average daily weight gain of the 20% fermented cassava residue group were significantly increased (P<0.05), and the feed to gain ratio was significantly decreased (P<0.05), the content of total protein and albumin in serum was significantly increased (P<0.05), and the content of urea nitrogen was significantly decreased (P<0.05). The activity of glutamic-oxaloacetic transaminase in the serum of the 10% and 20% fermented cassava residue groups was significantly decreased (P<0.05), the content of creatinine in the 10% and 30% fermented cassava residue groups was significantly increased (P<0.05), the content of uric acid in the 20% and 30% fermented cassava residue groups was significantly increased (P<0.05). Compared with the control group, the weight gain income of Hu sheep in each fermented cassava residue group increased by 10.68%, 23.76%, 16.57%, and the breeding profits increased by 10.36%, 36.92%, 14.99%, respectively. The results show that 20% fermented cassava residue in the diet can improve the production performance of Hu sheep, and the economic benefit of breeding is good. [ABSTRACT FROM AUTHOR]

To achieve a green mine with zero tailings discharge, a lead zine mine in Sichuan has undertaken a study on the comprehensive and full utilization of tailings after detoxification. Through brief field surveys and investigations of the mine's technical conditions, along with experimental analysis of tailings characteristics, 2 schemes were proposed: ungraded tailings backfill and graded fine tailings backfill (coarse tailings used as building materials). Due to the swellability of minerals during grinding, the space in the mined-out areas cannot accommodate all the tailings generated during mining. Thus, it is decided that the ungraded tailings be graded, with a grading threshold of 74 µm, resulting in a coarse tailings productivity of 39.5%. The coarse fraction is dewatered and used as construction sand material, while the fine fraction is thickened and dewatered for use as backfill aggregate, thereby achieving zero tailings discharge. Based on the characteristics of the fine fraction, a paste storage thickener was selected for efficient thickening and dewatering, and the cementing powder from nearby cement factory is used for backfill with cemented. graded fine tailings. As can be seen from cost analysis of the 2 utilization schemes, 3 422, 1 yuan can be saved daily by backfill with graded tailings, showing significant results. The research achievement can be a reference for similar mines when constructing tailings-free green mines. [ABSTRACT FROM AUTHOR]

Objectives This study examines the effectiveness and efficiency of intensive psychodynamic psychotherapy for severely impaired patients. Method: 104 patients in four public mental health centers underwent intensive psychodynamic psychotherapy. The number and duration of psychiatric hospitalizations were monitored for these patients from one year before therapy to eight years after. Several outcome variables were measured every six months, six times in total over two and a half years, using a longitudinal design. A multi-level analytic approach was applied to account for repeated measurements and missing data. Results: Significant improvement was found in all three symptomatic outcome measures (SCL-90, OQ-45, BDI) throughout treatment. The numbers of psychiatric hospitalizations and psychiatric hospitalization days decreased significantly from the level they were in the year before the start of psychodynamic treatment to three years after the start of treatment. These results were maintained for at least up to eight years. After capitalization, the overall cumulative 127.47-day decrease in hospitalization days equals savings of 115,850 NIS. The average cost of treatment after capitalization was 26,770 NIS. The insurer's estimated direct savings is 89,080 NIS (24,054 $). Conclusion: These findings support the hypothesis that psychodynamic psychotherapy is clinically effective and economically efficient for severely impaired patients. [ABSTRACT FROM AUTHOR]

The era of the knowledge economy is defined by the pivotal role of knowledge and information in economic production, dissemination, and utilization. Information technology stands as a cornerstone in propelling the advancement of the knowledge economy. The transformative impact of information technology has been a driving force in ushering in the knowledge economy era. Amid this backdrop, the blended teaching mode emerges as a novel pedagogical approach infused with information technology, demanding an evaluation of its economic merits as it gains traction in educational practice and adoption. The implementation of blended teaching modes within university settings necessitates considerable investments from educators, encompassing teaching efforts, human resources, and technological infrastructure. The linchpin in introducing blended teaching modes is whether they yield a superior economic benefit that justifies the resources expended. To scrutinize whether the blended teaching mode possesses the potential for heightened economic benefits, this study embarks on an empirical journey, investigating its influence on student learning outcomes through rigorous experimentation. This investigation formulates twelve research hypotheses designed to explore intricate relationships between latent constructs through multiple linear regression tests. The study's findings confirm that the blended teaching mode can generate heightened economic benefits. These outcomes underscore the pedagogical and economic promise inherent in the integration of technology and innovative teaching methods within higher education, aligning with the imperatives of the knowledge economy.

The primary aim is to provide a review of the benefits of agritourism for developing countries, such as the Central Asian country of Uzbekistan. This literature review discusses the importance of agritourism as a sustainable tourism strategy for the government and key stakeholders to support raising the standard of living and poverty levels of farmers and their families who are living in rural areas of Uzbekistan. The research method uses a literature review of the scientific research on agritourism in Uzbekistan. This was achieved through an extensive search of databases through the use of keywords that were collected to analyze and determine whether there were any gaps in the literature. This paper concludes that for less developed countries such as the Republic of Uzbekistan, agritourism is still in its initial stages of development and provides mainly economic benefits. This is because, in Uzbekistan, almost half of its population lives in rural areas and relies on the economic benefits of agriculture as their main source of subsistence and employment. However, in the future, there is a need to further develop new and innovative programs for agritourism businesses that can also promote the environmental and socio-cultural benefits for tourists to increase visitation to rural areas.

This study contributes to the literature examining public acceptance of carbon capture and storage (CCS) projects in the US. The examination of factors that shape public support for CCS projects provides policymakers with insights to address public concerns, balance CCS development with public sentiments, and make informed decisions about optimal locations and timing. Based on a nationally representative survey on 1850 respondents, the study finds that in the US, there is very low familiarity (6.4%) regarding CCS technology and some limited opposition (11.5%) to increased CCS development. Regression results suggest that support for increased CCS projects in the US is influenced by perceptions of technical and social risks (leakage and community danger, respectively) but not cost of living risks, perceptions of environmental and economic benefits, familiarity with the technology, confidence in government regulations, and a desire for the US to lead in CCS. We fail to find the 'Not-in-My-Backyard' effect, and individuals supporting the development of more CCS in their states also support it at a national level. Understanding these factors helps policymakers anticipate challenges in implementing CCS initiatives and allows for the development of strategies to address concerns. [ABSTRACT FROM AUTHOR]

This study examines the economic impacts of the North Warning System (NWS) modernization. It begins by first providing a summary of the creation and evolution of the North American Aerospace and Defense Command (NORAD) and the NWS with a specific intention of setting the stage for the discussion on subsequent areas. Understanding how NORAD and the NWS developed to where it is today is important to understand the choices available to the Canadian government moving forward. Next, the current security environment in Canada's North will be reviewed. The impact of climate change and global warming, new technology, and new threats changes the strategic environment in the North and Canada needs to revisit how it approaches these challenges. Based on this review of the security environment, the literature on socioeconomic studies, electoral districts and defence spending in the North can be presented along with the empirical data that exists from past studies. The study looks at five scenarios taking a rough order of magnitude look at possible economic benefits to Canada's three northern territories and Labrador based on the requirement for modernizing the NWS, a critical issue for the future defence of Canada and North America.

The combination of no-till farming and green manure is key to nourishing the soil and increasing crop yields. However, it remains unclear how to enhance the efficiency of green manure under no-till conditions. We conducted a two-factor field trial of silage maize rotated with hairy vetch to test the effects of tillage methods and returning. Factor 1 is the type of tillage, which is divided into conventional ploughing and no-tillage; factor 2 is the different ways of returning hairy vetch as green manure, which were also compared: no return (NM), stubble return (H), mulching (HM), turnover (HR, for CT only), and live coverage (LM, for NT only). Our findings indicate that different methods of returning hairy vetch to the field will improve maize yield and quality. The best results were obtained in CT and NT in HM and LM, respectively. Specifically, HM resulted in the highest dry matter quality and yield, with improvements of 35.4% and 31.9% over NM under CT, respectively. It also demonstrated the best economic and net energy performance. However, other treatments had no significant effect on the beneficial utilization and return of nutrients. The LM improved yields under NT by boosting soil enzyme activity, promoting nitrogen transformation and accumulation, and increasing nitrogen use efficiency for better kernel development. Overall, NTLM is best at utilizing and distributing soil nutrients and increasing silage maize yield. This finding supports the eco-efficient cultivation approach in silage maize production in the region. [ABSTRACT FROM AUTHOR]

Arctic melting is an effect of climate change; the use of fossil fuels in marine shipping emits large amounts of air emissions that impact climate change, and Arctic aquatic and human life. Swedish pulp and paper mills generate large amounts of waste and side streams that could be utilized. The production of forest-based biofuel may be a promising solution to achieve sustainable Arctic marine shipping. This review highlights the socio-economic impacts associated with the production of forest-based biofuel in Sweden, the related opportunities, challenges, knowledge gaps, and further need of research. From the economic perspective, it was found that the production and use of forest-based biofuel have short and long-term economic sustainability benefits: (a) short-term benefits, the use of the waste and side streams of the pulp and paper industry is a low-cost available feedstock, unlike first-generation biofuel from crops like corn forest-based biofuels neither require additional land use, water resources nor compete with food. (b) Long-term benefits: (i) the Swedish shipping sector depends on imported fossil fuels, these new biofuels can replace partly those imported fossil fuels that will reduce shipping costs, and generate economic benefits for local consumers. (ii) Usage of forest-based biofuels as blends with conventional fuels in existing engines will reduce greenhouse gas emissions from the Arctic shipping to the set limits in the region. (iii) One of the important socioeconomic impacts of forest-based biofuel production and use is the new job creation and employment opportunities that will impact the local communities and livelihoods of indigenous people in the area. From a societal perspective, stakeholder involvement is essential to address the sustainability challenges of biofuel production: EU policymakers need to encourage the production and use of biofuels by developing policies that promote biofuel use. Further studies are needed to develop more efficient and low-cost biofuel production routes, more investments in related research and development are required as well. Local indigenous communities must be involved in the decision-making process through surveys, local dialogues, and research studies. The production of forest-based biofuels has great potential and many social-economic impacts alongside the environmental benefits. [ABSTRACT FROM AUTHOR]

Phytosterols are 3-hydroxyl compounds with cyclopentadienanthrene as the backbone, which mainly exist in plant cell membranes in three forms: Free, esterified and glycoside. Phytosterols are precursors to the synthesis of steroid, vitamin D and many kinds of hormones. They are widely found in plant oils, vegetables, fruits, nuts, legumes and tubers. Phytosterols mainly include β -sitosterol, stigmosterol, canola sterol and so on, which are active substances with cholesterol structure. Phytosterols have many biological functions, such as regulating immunity, lowering cholesterol, antiinflammatory, antioxidant, promoting growth, preventing cardiovascular and cerebrovascular diseases. With the deepening of research on phytosterols, they have been widely used in animal breeding and production in recent years. Phytosterols can improve the antioxidant capacity and immunity of animal body, improve lipid metabolism, improve production performance, improve the quality of animal products, and increase the economic benefit of breeding. In order to better apply phytosterols in animal production, the physicochemical properties, active functions and the research progress of phytosterols in animal culture were reviewed in this paper, and some references were provided for their further promotion and application in animal production.

The experiment was to study the effects of different protein levels in the diet on the growth performance and meat quality of penned small tailed Han sheep lambs. A total of 75 male lambs of the small tailed Han sheep, approximately 90 days old, were randomly divided into three experimental groups: Group Ⅰ (low protein group, 12.16%), Group Ⅱ (medium protein group, 14.04%), and Group Ⅲ (high protein group, 15.70%), with five replicates per group and five male lambs per replicate. The preliminary trial lasted for 10 days, and the formal experiment lasted for 90 days. The results showed that the average weight gain and average daily weight gain of Group Ⅱ and Group Ⅲ were extremely higher than those of Group Ⅰ (P<0.01), and the feed to gain ratio was significantly lower than that of Group Ⅰ (P<0.05). The carcass weight and backfat thickness of Group Ⅰ were significantly lower than those of Group Ⅱ and Group Ⅲ (P<0.05), while the cooking loss, drip loss, brightness value, and yellowness value were significantly higher than those of Group Ⅱ and Group Ⅲ (P<0.05). The average daily income of the lambs in Group Ⅱ was 2.47 yuan/d, which was 0.74 yuan/d higher than that of Group Ⅰ and 0.39 yuan/d higher than that of Group Ⅲ. The study indicates that when the metabolizable energy level is between 11.52 and 11.57 MJ/kg, increasing the dietary protein level can improve the growth performance of barn feeding small tailed Han sheep and has a positive effect on the meat quality, with the highest economic benefit achieved at a crude protein level of 14.04%.

The aim of this experiment is to investigate the effects of reducing soybean meal as a substi‐ tute for diet on the growth performance, meat performance, and economic benefits of fattening small tailed Han sheep. 75 small tailed Han sheep with similar body weight of (41.64±1.19) kg and about 180 days were selected for the experiment and bred into male sheep. They were randomly divided into a control group, experimental groupⅠ, experimental group Ⅱ, experimental group Ⅲ, and experimental group Ⅳ. The crude feed in the control group's diet was made entirely of rolled silk soybean straw, while the ex‐ perimental group's diet was reduced in soybean meal. Different proportions of peanut seedlings were used as the crude feed instead of soybean straw. The fine to coarse ratio (60∶ 40) of the diet re‐ mained unchanged throughout the experiment, and the digestible energy and protein levels of diet of each group were similar. Fasting body weight and body size were measured at the begin‐ ning and end of the experiment, meat performance was measured at the end of the experiment, and economic benefits were calculated. The results showed that: ① compared with the control group, the aver‐ age daily weight gain of each experimental group was significantly increased (P<0.01), with the best weight gain effects observed in experimental groupⅠ, experimental groupⅡ, and experimental group Ⅲ, while there was no significant difference in body size indicators among the groups (P>0.05). ② Com‐ pared with the control group, the experimental groups showed a significant increase in back fat thickness and GR value (P<0.05), while there was no significant difference in slaughter rate, net meat rate, and eye muscle area between the experimental groups and the control group (P>0.05). ③ Compared with the ex‐ perimental groups, the control group had the highest dripping loss and yellowing value of lamb, both sig‐ nificantly higher than the experimental groups (P<0.05). ④ The economic benefits of each experimental group were significantly higher than those of the control group (P<0.01). The reduction of soybean meal as a substitute for diet has varying degrees of impact on the growth performance, meat performance, and economic benefits of fattening small tailed Han sheep. The experimental groupsⅠ, Ⅱ, and Ⅲ have a bet‐ ter effect and higher economic benefits. [ABSTRACT FROM AUTHOR]

There has been a debate over many decades concerning the benefits of lifelong learning that have been expressed both in economic and non-economic terms, the latter often expressed in terms of contributions to health and well-being, and to civic solidarity. The extent to which these benefits can be evidenced however remains somewhat elusive and at best mixed. In this paper, I trace the ways in which lifelong learning has emerged in policy discourse in the UK since the 1980s, the arguments and evidence for its benefits and the means by which it has been supported and implemented. In particular, the paper is concerned with the role of the higher education sector in the UK with a particular focus on Scotland. [ABSTRACT FROM AUTHOR]

The implementation of economic activity in sanitary and protective and other protective zones at the modern stage has become a difficult and urgent problem. First of all, there is a need to understand the impact of economic activity on the state of these zones. It is important to investigate what consequences arise as a result of the operation of enterprises and the implementation of various economic processes in such special territories. The second important problem is to understand the legal aspects related to economic activity in sanitary and protective zones. This includes an analysis of the legal norms, rules and restrictions that govern such activities, as well as an assessment of the effectiveness of existing legal mechanisms to ensure the protection of these areas. The formulation of the problem also involves consideration of strategies and methods that can ensure ecological compatibility of economic activity in protected zones. Research in this direction is aimed at identifying optimal approaches, technologies and practices that contribute to the conservation of natural resources, reducing the negative impact on the environment and increasing the sustainability of ecosystems. In addition, it is important to consider the social, economic and environmental benefits and challenges associated with economic activity in sanitary protection and security zones. Decision-making in these matters has a significant impact on the development of territories, the provision of employees of enterprises, as well as the preservation of natural ecosystems. The final issue is related to the role of the state in the control and regulation of economic activity in sanitary and protective zones. It is necessary to determine the effectiveness of existing mechanisms of state control, as well as to identify opportunities for their improvement and addition in order to ensure environmental safety and sustainable development of these special territories. In the context of legal aspects, it is important to establish clear norms and restrictions regulating economic activity in sanitary and protective zones. The legislation should define the requirements for the permissible level of pollution, the procedure for obtaining permits and monitoring the implementation of environmental standards. To ensure ecological compatibility of economic activity in protected zones, it is important to use strategies and methods aimed at preserving natural resources and reducing the negative impact on the environment. These can be the introduction of environmentally friendly technologies, energy efficiency, rational use of resources and the implementation of environmental management programs. One of the key aspects is the environmental responsibility of enterprises that carry out economic activities in protected zones. They must take an active part in preserving the natural environment, use environmentally safe materials and technologies, and also take into account the principles of sustainable development. Consideration of social, economic, and environmental benefits and challenges associated with economic activity in sanitary and protective zones is important for making appropriate decisions. Properly balanced economic activity can contribute to the creation of jobs, the development of the economy of territories and the well-being of communities, but it must also take into account social needs, the health of the population and the preservation of the natural environment.

Emission reduction in the construction sector is essential for China to achieve its carbon peaking and carbon neutrality goals. Construction waste recycling represents an important step in reducing the construction industry's carbon emissions; however, construction waste recycling potential has received little attention from the industry to date. This paper adopts the Life Cycle Assessment method, constructs a carbon potential quantification formula for different construction waste treatment modes, and evaluates the economic benefit of these methods. The study's main results are as follows. (1) For each unit (t) of construction waste disposal, the carbon potential of close-range off-site recycling is the lowest, that of public landfill is the highest, and that of recycling is intermediate. (2) The economic benefit evaluation shows that under the same conditions, the lowest total disposal cost for construction waste per unit (t) is via recycling and resourcing, indicating that this approach combines economic benefits, environmental friendliness, and sustainability. (3) Eco-friendly bricks produced by construction waste recycling have reduced carbon potential requirements compared to traditional bricks; thus, the construction waste treatment process plays a successful role in reducing carbon potential. This study's conclusions enrich and improve the theory of construction waste resource management and can be used as a reference basis for the government to formulate emission reduction strategies for the construction industry and provide guidance for enterprises related to construction waste recycling.

Water scarcity under global climate change has impacted decreased agricultural productivity. Determining the suitable crop rotation strategy under water scarcity applicable to a specific region requires an evaluation of crop suitability, water scarcity, and economic benefits to farmers. This paper aims to improve agricultural productivity and economic benefits through crop rotation strategies under climate change. We developed seven crop rotation strategies, including rice, soybean, maize, and sweet potatoes, that were determined based on preliminary results of the crop suitability index using the EcoCrop model. The water scarcity index (WSI) in historical and future under climate change conditions is estimated using the CropWAT model. In addition, the economic benefit of each crop rotation strategy is evaluated. Finally, multi-criteria decision analysis (MCDA) using the Analytical Hierarchy Process (AHP) was employed to select the most suitable crop rotation strategy applicable to Taoyuan City, Taiwan, based on crop suitability assessment, water scarcity, and economic benefit analysis. Our result shows that WSI values are 0.37, 0.50, and 2.28 in the dry years of 2004, 2015, and 2020, respectively, due to decreasing rainfall and increasing temperatures. The 10-year and 20-year averages were 0.4 and 0.35, respectively, indicating that the issue of agricultural water scarcity is intensifying year by year. Cultivating sweet potatoes has less vulnerability to water scarcity by up to 90 % under climate change than rice. Sweet potatoes also generate farmers’ income, which increases by 338 %, considering both rain-fed and irrigation efficiency conditions. Finally, the MCDA-AHP revealed that sweet potatoes and soybean-maize rotation in Taoyuan City were the most suitable and profitable crops for cultivating in Taoyuan City, especially under high and severe agriculture water stress events. Implementing a crop rotation strategy involving sweet potatoes and soybean-maize can effectively mitigate the impact of climate change and extreme drought on crop yield and ensure a stable income for farmers. Integrated irrigation and crop rotation strategies are crucial for providing farmers and other stakeholders with more informed decision-making in agriculture sectors while enhancing water use efficiency.

This study investigated the effects of replacing whole-plant corn silage (CS) with different proportions of sweet sorghum silage (SS) on slaughter performance, meat quality and economic aspects of beef cattle. Fifteen 12- to 15-month-old Simmental steers were randomly divided into five groups with different diets. The experimental period consisted of a 15-day dietary adaptation period and a 120-day trial period. The control group contained 30% corn silage (30%CS), while the experimental groups contained 30% (30%SS), 50% (50%SS), 70% (70%SS) and 90% (90%SS) sweet sorghum silage in the forage, respectively. Compared with 30%CS, the average daily intakes (ADIs) and average daily gains (ADGs) in 50%SS and 70%SS were increased by 9.4% and 6.9%, 47.3% and 12.1%, respectively. The carcass net meat rates (CMRs) of 50%SS (77.8%) and 70%SS (75.3%) were significantly higher than that of 30% CS (73.5%). Replacing CS with SS increased the content of crude protein (24.14% vs 22.42%, p < 0.05), unsaturated fatty acids (45.95% vs 41.83%, p < 0.05), C20:4 fatty acids (4.13% vs 2.76%), beef marbling and net profit in 50%SS. Therefore, replacing CS with SS in diets has effects on the slaughter performance and meat quality of beef cattle as well as economic benefits.
