This paper describes a methodology for assessing farms that considers the multi-functionality derived from the requirements and expectations of the agricultural sector. To this end an original, multicriteria method was developed for assessing farms based on their individual data. Five dimensions were assessed (production, economic, financial stability, environmental, social & other), representing the most important aspects of farming. The overall assessment based on these five dimensions aims to express the total sustainability rate of the farms. The methodology used to develop this assessment is described. The results of the assessment for 2016 are presented and classified according to various factors and are linked to other important indicators. The data used is from the Farm Accountancy Data Network database in the Czech Republic.
本文描述了一种评估农场的方法,该方法考虑了从农业部门的要求和期望中衍生的多功能。为此,开发了一种原始的、多标准的方法,根据农场的个人数据对其进行评估。评估了五个方面(生产、经济、金融稳定、环境、社会和其他),代表了农业最重要的方面。基于这五个维度的总体评估旨在表达农场的总可持续性。描述了用于进行这一评估的方法。2016年的评估结果将根据各种因素进行呈现和分类,并与其他重要指标相关联。所使用的数据来自捷克共和国农场会计数据网络数据库。

The causes of food price spikes are complex, and their impact on different countries varies depending on production levels and the varied policies in place. Countries in Central Asia and the Caucasus (CAC) region have implemented a wide range of reforms that vary in form and speed. The existing scientific literature reports about the consequences of price spikes in CAC; however, to date, a comparison of impact between those countries has not been made in terms of the entire supply chain perspective. Therefore, this study investigates the impact of the price spikes on the entire wheat supply chain for the first time in CAC and discusses the role of policies. Another contribution of this study is an evidence-based analysis of the role of policy reformation in maintaining food security under price shocks. Our results indicate a very limited effect of price interventions and trade restrictions on dampening wheat prices in all countries. We find that only trade diversification policy had a positive effect on reducing the level of price spikes, and thus it might be a suitable policy measure for maintaining food security.
粮食价格飙升的原因是复杂的,其对不同国家的影响因生产水平和不同的政策而异。中亚和高加索地区的国家实施了形式和速度各异的广泛改革。现有的科学文献报道了CAC价格飙升的后果;然而,迄今为止,还没有从整个供应链的角度对这些国家之间的影响进行比较。因此,本研究首次在CAC中考察了价格飙升对整个小麦供应链的影响,并讨论了政策的作用。本研究的另一个贡献是基于证据分析了政策改革在价格冲击下维持粮食安全方面的作用。我们的研究结果表明,在所有国家,价格干预和贸易限制对抑制小麦价格的影响都非常有限。研究发现,只有贸易多样化政策对降低价格上涨水平具有积极作用,因此贸易多样化政策可能是维持粮食安全的合适政策措施。

This paper investigates the development and structure of the fixed assets of Czech farms and their investment behaviour. We use data from a long-term (2003–2016) survey of farms and categorise farms into three groups according to their share of agricultural land in less favoured areas. The development of tangible fixed assets and their structural development points to the importance of investments to agricultural holdings. Above all, there is an extensive trend of investing in the land, but purchases of land are likely to affect the growth of the relative age of tangible fixed assets, especially the obsolescence of buildings that are not sufficiently modernised by farms. Results of the accelerated model indicate that there is an absence of soft budget constraints but a presence of capital imperfections and high importance of both operating and investment subsidies when deciding on investments in fixed assets.
本文研究了捷克农场固定资产的发展和结构及其投资行为。我们使用了一项长期(2003-2016)农场调查的数据,并根据农场在不太受欢迎地区的农业用地份额将农场分为三组。有形固定资产的发展及其结构发展表明了农业投资的重要性。最重要的是,投资土地的趋势非常广泛,但购买土地可能会影响有形固定资产相对年龄的增长,尤其是那些没有被农场充分现代化的建筑物的过时。加速模型的结果表明,在决定固定资产投资时,不存在软预算约束,但存在资本不完善和运营补贴和投资补贴的高度重要性。

Unforeseen important changes in price can present a significant risk in the market. The price fluctuation of agricultural commodities has raised concern for studying the volatility of different agricultural products. A persistent volatility in prices causes continued uncertainty in the market. Higher price volatility is to be mitigated by higher management costs and the higher cost of risk mitigation is often converted into higher producer prices. The aim of this paper is to investigate the price volatility of producer and consumer meat prices and to capture the volatility spillover along the Finnish meat supply chain. The Generalised Autoregressive Conditional Heteroskedasticity – Baba, Engle, Kraft and Kroner (GARCH-BEKK) model is applied to analyse shocks and volatilities of the prices and to estimate whether the price volatility is flowing from the first price level (producer) to the second price level (consumer), using monthly price indices. An asymmetric volatility spillover effect was detected in the poultry meat and a unidirectional, volatility spillover effect, from consumer to producer, is observed for pork prices. The findings of this study could serve as a tool for forecasting meat producer and consumer prices, which could assist the Finnish government with endorsing policy options to alleviate the price volatility impact, to protect both consumers and producers from its negative effects.
价格的不可预见的重大变化会给市场带来重大风险。农产品价格的波动引起了人们对不同农产品波动的研究。价格的持续波动给市场带来了持续的不确定性。更高的管理成本将减轻价格的更大波动,而降低风险的更高成本往往转化为更高的生产者价格。本文的目的是研究生产者和消费者肉类价格的波动,并捕捉芬兰肉类供应链上的波动溢出效应。应用广义自回归条件异方差- Baba, Engle, Kraft和Kroner (GARCH-BEKK)模型分析价格的冲击和波动,并使用月度价格指数估计价格波动是否从第一价格水平(生产者)流向第二价格水平(消费者)。在禽肉中发现了不对称的波动溢出效应,而在猪肉价格中发现了从消费者到生产者的单向波动溢出效应。本研究的结果可以作为预测肉类生产者和消费者价格的工具,这可以帮助芬兰政府批准政策选择,以减轻价格波动的影响,保护消费者和生产者免受其负面影响。

In order to alleviate the potential damage from climate change and fulfil the requirements contracted in the Paris Agreement (COP 24), China has promulgated the mandatory regulation on ethanol-blend gasoline to reduce current levels of CO2 emissions. Since large-scale bioenergy development involves various aspects such as feedstock selection (energy crops, crop wastes), technology alternatives (conventional and cellulosic ethanol, pyrolysis), government subsidy (land use, energy crop subsidy) and carbon trade mechanism, an analysis that integrates economic, environmental, and social effects is necessary to explore the optimal biofuel strategy and social effects. This study proposes a price endogenous, partial equilibrium mathematical programming model to investigate how the selection of bioenergy crops and bioenergy technologies influences the amount of net bioenergy production, carbon sequestration, government subsidies, and cultivation patterns. We show that the conjunctive use of agricultural wastes can be an effective addition to current biofuel production. The results also indicate that at high gasoline and emissions prices, more land used for the energy crop program results in a significant change in government expenditure. In addition, net emissions reduction and emissions offset efficiency can vary substantially when different bioenergy techniques are adopted.
为了减轻气候变化的潜在危害,并履行《巴黎协定》(COP 24)的要求,中国颁布了对乙醇混合汽油的强制性规定,以减少目前的二氧化碳排放水平。由于大规模生物能源开发涉及原料选择(能源作物、作物废弃物)、技术替代(常规和纤维素乙醇、热解)、政府补贴(土地利用、能源作物补贴)、碳交易机制等多个方面,因此需要综合分析经济、环境和社会效应,探索最优的生物燃料战略和社会效应。本研究提出了一个价格内生的部分均衡数学规划模型,以研究生物能源作物和生物能源技术的选择如何影响生物能源净产量、碳固存、政府补贴和种植模式。我们表明,农业废弃物的联合利用可以有效地补充当前的生物燃料生产。研究结果还表明,在汽油和排放价格较高的情况下,用于能源作物项目的更多土地会导致政府支出的显著变化。此外,当采用不同的生物能源技术时,净减排和排放抵消效率可能有很大差异。

Land redistributive policies can be viewed as effective tools for reducing rural poverty mainly because agriculture continues to be a major source of rural livelihood and a contributor to rural economic growth. For the structural changes and economy-wide impacts, including behavioural changes of rural land distribution, to be assessed and captured through time, a South African Social Accounting Matrix can be used as a database to construct a dynamic computable general equilibrium simulation model to simulate the potential impact on household welfare in South Africa. This study seeks to assess how government redistributive policies may affect household welfare in shortand long-run, focusing on poverty and income distribution in South Africa by applying a dynamic computable general equilibrium microsimulation model. The results showed that rural land distribution increases poor household income through an increase in factor by an average of 0.828. However, for most macroeconomic variables, the impact is negative in the short-run with a gradual increase in the long-run. The results support the claim that rural land distribution coupled with agriculture investment and government support can be effective in improving household welfare.
土地再分配政策可被视为减少农村贫困的有效工具,主要是因为农业仍然是农村生计的主要来源和农村经济增长的贡献者。为了评估和捕捉结构变化和整个经济的影响,包括农村土地分配的行为变化,可以使用南非社会会计矩阵作为数据库,构建一个动态可计算的一般均衡模拟模型,以模拟对南非家庭福利的潜在影响。本研究旨在评估政府再分配政策在短期和长期如何影响家庭福利,重点关注南非的贫困和收入分配,采用动态可计算一般均衡微观模拟模型。结果表明,农村土地布局通过增加因子平均增加0.828增加贫困户收入。然而,对于大多数宏观经济变量来说,这种影响在短期内是负面的,在长期内逐渐增加。研究结果支持了农村土地分配与农业投资和政府支持相结合能够有效提高农户福利的观点。

This paper studies the relationships between adherence to the Mediterranean diet, food-related information, and possible effects they could jointly exert on weight status. The empirical analysis was conducted via a consumer survey using face-to-face interviews, and a structural equation model was implemented to the data analysis. This model choice was led by its ability to simultaneously evaluate multiple constructs. The results outline the central role played by adherence to the Mediterranean diet and food-related information, both in terms of nutritional knowledge and expert recommendations, which seem to be the key drivers affecting healthy weight. Moreover, food label use increases the nutritional knowledge of consumers, which in turn favours a healthy diet.

Changes in the retail prices of pasteurised milk, purchase prices, and the price relationship between retail prices for pasteurised milk and other food products are analysed for Poland during the period from 2004–2018. In addition, the paper presents factors affecting changes in milk prices in Poland and characterises the Common Agricultural Policy (CAP) on the milk market. The adoption of a long period of analysis allows for the study of periods of both high and low variability. The data analysis uses various methods including the Augmented Dickey-Fuller (ADF) test and the Autoregressive-Moving-Average Model (ARMA). The milk market showed significant response because it was one of the few that was strongly administered by the European Union. These policies led to a significant increase in milk prices in the analysed period. The average price of pasteurised food milk increased by 63% in 2003–2015, and the purchase farm price of milk increased by 91.74%. The situation changed when the production limits were eliminated after 2015. In the initial period after quotas ended, the price of milk decreased and then increased. Similar changes were observed in other EU countries. Even short-term fluctuations associated with economic crises did not significantly affect the milk market.
分析了2004-2018年期间波兰巴氏杀菌奶零售价格的变化、采购价格以及巴氏杀菌奶零售价格与其他食品之间的价格关系。此外,本文提出了影响波兰牛奶价格变化的因素,并介绍了共同农业政策(CAP)对牛奶市场的影响。采用长周期的分析可以同时研究高变异性和低变异性的周期。数据分析使用了多种方法,包括增强迪基-富勒(ADF)检验和自回归移动平均模型(ARMA)。牛奶市场表现出明显的反应,因为它是少数几个受到欧盟严格管理的市场之一。在分析期间,这些政策导致牛奶价格大幅上涨。2003-2015年,巴氏杀菌食品奶的平均价格上涨了63%,牛奶的收购农场价格上涨了91.74%。2015年以后,生产限制被取消,情况发生了变化。在配额结束后的最初一段时间里,牛奶的价格先是下降,然后上升。其他欧盟国家也出现了类似的变化。即使是与经济危机相关的短期波动也没有显著影响牛奶市场。

Even short-term fluctuations associated with economic crises did not significantly affect the milk market.","PeriodicalId":48961,"journal":{"name":"Agricultural Economics-Zemedelska Ekonomika","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2020-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81201249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper describes a problem of optimal agricultural land treatment using aviation. The studied problem consists of determining the optimal routes for a given set of aircraft used for chemical treatment of arable agricultural land divided into parcels. This NP (nondeterministic polynomial time) problem is represented on a graph and a mixed integer mathematical programming model of the problem is formulated. This mathematical model is a specific variant of the multi-depot vehicle routing problem where a min-cost plan for the transportation of a homogeneous product (chemicals used for land treatment) from different supply locations (airfields) to different demand locations (agricultural parcels) should be generated. Some specifics of the agricultural land chemical treatment are described in the paper and the following specific conditions are taken into consideration: each parcel is treated only by one way of treatment and one aircraft; for each aircraft its chemical and fuel reservoir capacities are sufficient to serve its route. The complexity of the problem and the impossibility to obtain exact solutions for larger dimensions of the problem led to the formulation of a special heuristics which is presented in this paper. Numerical experiments are successfully conducted for larger problem dimensions and results are presented.
本文描述了利用航空进行农用地优化处理的问题。所研究的问题包括确定一组给定的飞机用于化学处理可耕地的最佳路线。将该NP(不确定多项式时间)问题用图表示,建立了该问题的混合整数数学规划模型。这个数学模型是多仓库车辆路线问题的一个特殊变体,在这个问题中,同一种产品(用于土地处理的化学品)从不同的供应地点(机场)运输到不同的需求地点(农田)的最小成本计划应该被生成。本文介绍了农用地化学处理的一些具体情况,并考虑了以下具体情况:每个地块只采用一种处理方式和一架飞机;对每架飞机来说,它的化学药品和燃油储存库的容量足以服务它的航线。考虑到问题的复杂性和问题在较大维度上不可能得到精确解,本文提出了一种特殊的启发式方法。在较大的问题维度下,成功地进行了数值实验,并给出了实验结果。

Models and methods of spatial econometrics are gaining more and more popularity. Their advantage is the opportunity to examine the interrelationships between individual territorial units. These methods, apart from the own potential of the region, take into account the impact of neighbouring objects and location in space. The aim of the study is to examine the relationship between the potential and the level of competitiveness of individual European Union countries in the field of slaughter cattle production. In addition, the paper attempts to determine the specialisation of individual EU countries in the production of slaughter animals by sector. The analysis covered the years 2010–2016, using Eurostat data. The obtained results allow indicating countries in which there is a strong concentration of income potential (Sweden, Spain, Great Britain, France and Belgium). Countries in which the highest values of the potential quotients in the entire European Union are distinguished (Poland, Finland and Belgium).
空间计量经济学的模型和方法越来越受到人们的重视。它们的优势是有机会检查各个领土单位之间的相互关系。这些方法除了考虑区域本身的潜力外,还考虑到邻近物体的影响和空间中的位置。这项研究的目的是审查欧洲联盟各国在屠宰牛生产领域的潜力和竞争力水平之间的关系。此外,本文试图确定个别欧盟国家的专业化生产屠宰动物的部门。该分析涵盖了2010年至2016年,使用的是欧盟统计局的数据。所得结果可以指出收入潜力高度集中的国家(瑞典、西班牙、英国、法国和比利时)。在整个欧盟中,潜在商数最高的国家(波兰、芬兰和比利时)是有区别的。
