Agricultural production and farm management are inextricable, since managerial aspects for safe and of high-quality food products have led to the development of successful production plans but multifaceted controversies as well. These controversies arise from the focus of policymakers, especially in the EU, to the environmental aspects of agricultural production, creating conflicting objectives for farmers. Energy from biomass derivatives could play a significant role in the dispute for economic and environmental sustainability in agriculture, along with the formulation of agro-energy districts. In this context, an MCDM model was developed integrating LCA data for the assessment of economic, environmental and energy sustainability regarding thirteen major crops in the Region of Central Macedonia in Greece. The model's objectives consist of maximization of farmers' gross income, minimization of emissions coming from farming practices and maximization of energy potentially coming from biomass. Furthermore, three different scenario-based directions allocate different weights to the respective objectives, creating different managerial strategies. The optimal production plan was the scenario in which the weights were allocated by goal programming. The optimal plan proposes the cultivation expansion of energy crops, tree crops, alfalfa and hard wheat to a higher degree. Moreover, a significant reduction to the cultivated areas of tobacco, rice, barley and soft wheat could lead to a potentially viable production plan.
农业生产和农场管理是不可分割的,因为安全和高质量食品的管理方面导致了成功的生产计划的制定,但也引发了多方面的争议。这些争议源于政策制定者,特别是欧盟的政策制定者对农业生产环境方面的关注,为农民创造了相互冲突的目标。生物质衍生物的能源可以在农业经济和环境可持续性的争端中发挥重要作用,同时制定农业能源区。在此背景下,开发了一个MCDM模型,该模型整合了LCA数据,用于评估希腊中马其顿地区13种主要作物的经济、环境和能源可持续性。该模型的目标包括农民总收入的最大化、农业实践排放的最小化以及生物质潜在能源的最大化。此外,三个不同的基于情景的方向为各自的目标分配了不同的权重,从而形成了不同的管理策略。最佳生产计划是通过目标规划分配权重的情景。优化方案提出了能源作物、林木作物、苜蓿和硬质小麦的种植规模更大程度的扩大。此外,大幅减少烟草、水稻、大麦和软小麦的种植面积可能会产生一个潜在的可行生产计划。

Nowadays, many financial and academic practitioners explore the area of high-frequency forecasting in new dimensions. Research on agricultural commodities is an important issue for food policy and security. This paper is focused on the causality between the spot prices and futures prices of the main traded agricultural commodities. Thus, the Granger causality was used to identify the relationship between spot and futures prices of commodities. Our results show the Granger causality between cash prices and futures prices of wheat and cocoa. However, there is also causality in the opposite direction in the case of wheat. Causality could be related, among other things, to a specific market position of the commodity, food policy, historical aspects, the sensitivity of the market, speculation activity, tax policy, and particular interconnection of the market with the energy commodities market. In the price process of cash and futures wheat prices, inventories and storage play an important role.
如今,许多金融和学术从业者在新的维度上探索高频预测领域。农产品研究是粮食政策和粮食安全的重要问题。本文主要研究了主要农产品现货价格与期货价格之间的因果关系。因此,使用格兰杰因果关系来确定商品现货和期货价格之间的关系。结果表明,小麦和可可现货价格与期货价格之间存在格兰杰因果关系。然而,在小麦的情况下,也存在相反方向的因果关系。除其他事项外,因果关系可能与商品的特定市场地位、食品政策、历史方面、市场的敏感性、投机活动、税收政策以及市场与能源商品市场的特定互连有关。在小麦现货价格和期货价格的价格过程中,库存和储存量起着重要的作用。

The article aims to define the Czech Agro-Food supply chain and develop financial metrics to quantify the economic value added generated within the supply chain. The study is based on a sample of complete financial statements from 2011 to 2018 from the agro-food organisations. The authors prove that the retail sale sector generates high shareholder value. Contrary to that, the wholesale sector´s shareholder value deteriorated over the respective period owing to reinforced capital intensity measures, resulting in low profitability. A special case is primary agricultural production, where the low shareholder value is offset by public transfers influencing all value drivers either directly or non-directly. These constantly changed, both in the single sector and financial supply chain, thus concluding the latter is dynamic in its nature. The primary agricultural production (Agro) faced specific conditions due to significant public transfers in the form of subsidies etc., thus influencing non/directly all shareholders´ value drivers and consequently reducing the originally expected vulnerability. The authors have found that the shareholder value is not generated and distributed evenly within the Czech Agro-Food supply chain; therefore, the “scissors” are expending in favour of the Retail sector at the expense of the others, especially of the Agro sector.
本文旨在定义捷克农产品食品供应链,并制定财务指标来量化供应链中产生的经济附加值。该研究基于农业食品组织2011年至2018年的完整财务报表样本。作者证明,零售业产生了高股东价值。与此相反,由于资本密集措施的加强,批发行业的股东价值在相应时期内恶化,导致盈利能力低下。一个特殊的情况是初级农业生产,低股东价值被直接或非直接影响所有价值驱动因素的公共转移所抵消。无论是在单一部门还是在金融供应链中,这些都在不断变化,从而得出结论,后者本质上是动态的。由于以补贴等形式进行的重大公共转移,初级农业生产(Agro)面临特定条件,从而影响了非/直接所有股东的价值驱动因素,从而降低了最初预期的脆弱性。作者发现,股东价值在捷克农业食品供应链中的产生和分配并不均匀;因此,“剪刀手”的支出有利于零售业,而牺牲了其他行业,尤其是农业部门。

In terms of water resources, Iran has less fresh water than its population demands. Also, due to climate change, inefficient management and excessive consumption of this vital resource, the water shortage situation is becoming more critical day by day. Searching for a solution for sustainable use of water sources, this study proposes utilizing the Internet of things technology in order to implement smart irrigation in agricultural lands in Iran. Investigating the economic impact of the Internet of Things in Iran’s agriculture sector is the purpose of this article. The most important advantages of using smart irrigation are decreasing water consumption and increasing the productivity of agricultural yields (e.g., fruits, vegetables, etc.). This research attempts to predict Iran's economic growth in the event of smart irrigation implementation in agricultural fields and farms. The effect of investment in smart irrigation on water consumption and agricultural production is estimated by regression with cross-sectional data. In the end, by using the information obtained through the mathematical method, Iran's economic growth through GDP growth is estimated in the case if the Internet of things technology is fully implemented and the full benefits of using this technology are gained.
就水资源而言,伊朗的淡水供应量低于其人口需求。此外,由于气候变化、管理效率低下和对这一重要资源的过度消耗,缺水情况日益严峻。为了寻找可持续利用水源的解决方案,本研究建议利用物联网技术在伊朗的农田中实施智能灌溉。本文的目的是调查物联网对伊朗农业部门的经济影响。使用智能灌溉最重要的优势是减少用水量和提高农业产量(如水果、蔬菜等)的生产力。本研究试图预测在农田和农场实施智能灌溉的情况下伊朗的经济增长。智能灌溉投资对用水量和农业生产的影响是通过横断面数据的回归来估计的。最后,通过使用通过数学方法获得的信息,在充分实施物联网技术并获得使用该技术的全部好处的情况下,通过GDP增长来估计伊朗的经济增长。

This research aims to have a holistic view of the relationship between agriculture outcome/output and agricultural spending in India. The unique part of the study is that it highlighted the nexus between agriculture outputs from a historical point of view. The empirical part of this study is analyzed using the development of the co-integration method followed by the VECM model. The empirical analysis shows -a long-run association between agriculture spending and production, and this feedback is bidirectional. Agricultural production positively responds to agricultural spending in India both in the short and long run, especially in sowing seasons. However, the exciting finding of the study is that the speed of adjustment of agricultural spending on output is plodding. This implies that any shock of the agricultural production can be corrected by agricultural spending by just 20 percent, and it will take more than four years to stabilize the agricultural output with agricultural expenditure. Thus the tendency of agrarian spending to stabilize agrarian output in India is not so encouraging.
本研究旨在全面了解印度农业成果/产出与农业支出之间的关系。该研究的独特之处在于,它从历史的角度强调了农业产出之间的联系。本研究的实证部分使用协整方法的发展和VECM模型进行了分析。实证分析表明,农业支出和生产之间存在长期关联,这种反馈是双向的。从短期和长期来看,印度的农业生产对农业支出都有积极的反应,尤其是在播种季节。然而,这项研究令人兴奋的发现是,农业支出对产出的调整速度缓慢。这意味着,农业生产的任何冲击都可以通过20%的农业支出来纠正,而用农业支出来稳定农业产出需要四年多的时间。因此,印度农业支出稳定农业产出的趋势并不那么令人鼓舞。

Agricultural development nearby protected areas is required to minimize negative impacts from uses of off-farm resources as well as improper activities on the ecosystem and ensure livelihood for local farming communities. This research aims at assessing agricultural management practices and outcomes toward agroecology of rice cultivation in the buffer zone of Xuan Thuy National Park. Data were gathered from ecosystem managers, communal authorities and 96 rice cultivators living in 14 villages adjacently to the park in 2017-2018. “Traffic light” approach developed by FAO was used as an analytical technique to evaluate and visualize the environmental sustainability of rice cultivation with three levels of desirable, acceptable and unsustainable. The assessment reveals that none of the environmental indicators achieved at sustainable including fertilizer management, soil fertility, pesticide management, biodiversity preservation, and water conservation. Therefore, agricultural development in this area is required to be scrutinized for improvements especially the overdependency on nitrogen fertilizers, improper application of pesticides, limited adoption of biodiversity-friendly practices as well as other environmentally-friendly practices. The research highlights the need of implementing agroecological approach and special regime for protected area buffer zone to strengthen environmental preservation.
保护区附近的农业发展需要最大限度地减少场外资源使用以及不当活动对生态系统的负面影响,并确保当地农业社区的生计。本研究旨在评估宣道国家公园缓冲区水稻种植的农业管理实践和农业生态学结果。2017-2018年,数据来自生态系统管理者、社区当局和居住在公园附近14个村庄的96名水稻种植者。粮农组织制定的“红绿灯”方法被用作一种分析技术,以评估和可视化水稻种植的环境可持续性,分为可取、可接受和不可持续三个级别。评估显示,没有一项环境指标达到可持续水平,包括化肥管理、土壤肥力、农药管理、生物多样性保护和水资源保护。因此,需要仔细审查该地区的农业发展是否有所改善,特别是过度依赖氮肥、农药施用不当、生物多样性友好做法以及其他环保做法的采用有限。该研究强调了实施农业生态学方法和保护区缓冲区特殊制度的必要性,以加强环境保护。

The Contribution of Energy Use and Production to Greenhouse Gas Emissions: Evidence from the Agriculture of European Countries 能源使用和生产对温室气体排放的贡献:来自欧洲国家农业的证据
Q2 Economics, Econometrics and Finance Pub Date : 2022-09-30 DOI: 10.7160/aol.2022.140309

The submitted study investigates the role of energy use in agriculture and agricultural output in carbon dioxide emissions with the presence of instrumental variables such as rural population and urbanisation. The data set covers 27 European countries during the period 2010–2020. The quantitative approach was applied using cluster analysis with the previous identification of relations between variables by factor analysis. As the second approach, the Two-Stage Least Square (TSLS) model was estimated. Based on the results, three clusters were created. The heatmap demonstrated the similarity between the comprised countries. The most similar countries are Greece and Hungary, while the most different countries are Luxembourg and Malta. Performed TSLS analysis showed that an increase in energy use is associated with an increase in carbon dioxide emissions. On the other hand, greater agricultural output is associated with lower emissions. However, the statistical significance differs across the individual clusters.
提交的研究调查了农业能源使用和农业产出在二氧化碳排放中的作用,其中存在农村人口和城市化等工具变量。该数据集涵盖了2010-2020年期间的27个欧洲国家。定量方法使用聚类分析,之前通过因子分析识别变量之间的关系。作为第二种方法,对两阶段最小二乘(TSLS)模型进行了估计。根据结果,创建了三个集群。热图显示了各成员国之间的相似性。最相似的国家是希腊和匈牙利,而最不同的国家是卢森堡和马耳他。TSLS分析表明,能源使用的增加与二氧化碳排放的增加有关。另一方面,农业产量越高,排放量越低。然而,各个集群的统计显著性不同。

Performed TSLS analysis showed that an increase in energy use is associated with an increase in carbon dioxide emissions. On the other hand, greater agricultural output is associated with lower emissions. However, the statistical significance differs across the individual clusters.","PeriodicalId":38587,"journal":{"name":"Agris On-line Papers in Economics and Informatics","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44046186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The real context of climate change and pandemic has emphasized the enormous significance of agriculture to society and paved a path to digitization. Each country's agricultural digitalization strategies must not only focus on the technological aspects of the production system but as well present an overview of how this field of study is establishing and developing. To address this issue, a research was carried out to identify priority research questions concerning digital agriculture in Viet Nam, but with a view to also informing international contexts. The study applied a combination of methods including descriptive statistics, review of related researches reflecting the application of digital technology in agriculture, as well as systematic and institutional approaches to create the conditions for the development of digital agriculture. Concurrently, taking into account the readiness limitation of economic actors' for digital transformation is also presented in this study. Viet Nam is in the early stages of digital transformation in agriculture. Digital readiness is critical to grasping and implementing existing technologies and transforming agriculture. In order for the digital transformation to come into play in a positive way, the institutional decisions of the authorities are crucial to the major challenges facing Viet Nam's agriculture, such as digital inequalities, human resources, financial, and infrastructure constraints and inadequate awareness of existing technologies.
气候变化和疫情的真实背景强调了农业对社会的巨大意义,并为数字化铺平了道路。每个国家的农业数字化战略不仅必须关注生产系统的技术方面,还必须概述这一研究领域是如何建立和发展的。为了解决这一问题,开展了一项研究,以确定越南数字农业的优先研究问题,但同时也为国际背景提供信息。该研究结合了描述性统计、反映数字技术在农业中应用的相关研究综述以及系统和制度方法,为数字农业的发展创造了条件。同时,考虑到经济参与者对数字化转型的准备程度限制,本研究也提出了这一点。越南正处于农业数字化转型的早期阶段。数字化准备对于掌握和实施现有技术以及农业转型至关重要。为了使数字化转型以积极的方式发挥作用,当局的体制决策对越南农业面临的重大挑战至关重要,例如数字不平等、人力资源、财政和基础设施限制以及对现有技术认识不足。

The objective of this paper is to evaluate the position and financing needs of agri-food industry in Slovakia. There is a growth of agri-food sector which is reflected in growing demand for finance. Despite current favourable conditions on the financial market in Slovakia, some viable firms still face a credit constraint. Financing gap exists due to relatively high interest rates for some firms and due to their lack of sufficient collateral. Based on the survey results and focus group meetings we estimate the financing gap. Results show that there is potential for a further expansion of the financing market, with a financing gap estimated at EUR 36.8 mil. Small firms suffer the most from the financing gap and they constitute 77.4% of the gap. Financing gap and financing needs will be growing in the future. Firms need to increase investment to stay competitive on the market and need to adopt to changes in consumer preferences. This requires further investment into new technology and equipment. Tougher environmental requirements make firms invest into more environmentally friendly production processes. Furthermore, the sector is expected to be growing in the future. Financial instruments in the form of loan guarantees and interest rate subsidies would partly eliminate the existing financing gap. Small firms would benefit from simple and flexible financial instruments serving as guarantees for loans. Large firms would benefit from long-term loans supported by financial instruments. Policy-makers should place special attention on the use of financial instruments in agri-food sub-sectors with potential high value added and high employment.
本文的目的是评估斯洛伐克农业食品工业的地位和融资需求。农业食品部门的增长反映在对金融需求的增长上。尽管目前斯洛伐克的金融市场条件有利,但一些有生存能力的公司仍然面临信贷限制。由于一些企业的利率相对较高,并且缺乏足够的抵押品,因此存在融资缺口。根据调查结果和焦点小组会议,我们估计资金缺口。结果显示,融资市场有进一步扩大的潜力,融资缺口估计为3680万欧元,其中小企业受融资缺口影响最大,占缺口的77.4%。未来的融资缺口和融资需求将越来越大。企业需要增加投资以保持在市场上的竞争力,并需要适应消费者偏好的变化。这需要对新技术和设备进行进一步投资。更严格的环境要求促使企业投资于更环保的生产过程。此外,该行业预计将在未来增长。贷款担保和利率补贴形式的金融工具将部分消除现有的融资缺口。小企业将受益于作为贷款担保的简单而灵活的金融工具。大型企业将受益于由金融工具支持的长期贷款。决策者应特别注意在具有潜在高附加值和高就业率的农业食品分部门使用金融工具。
