Analysis of production and competitiveness on small beekeeping farms in selected districts of Serbia
Views:398The study researched the costs and returns on typical small beekeeping farms from five districts in Serbia. On the basis of the field research, data on the number of beehives,type of product, volume of production per beehive and values per measurement unit were collected.In order to demonstrate the competitiveness of various apicultural products, analysis of the available data was performed using analytical calculations. According to the analysis, the labour costs comprise about 49.65% to 64.15% of the variable costs on beekeeping farms in the Raška and Šumadija districts, respectively. Production is most economical on the bee farm in the district of Srem, where every dinar spent in production creates a value of 2.22 dinars, while the farm from the district of Raška is the least economical (1.32 din). Bee farms must reduce labour costs and re-direct their business orientation to other bee products, besides honey, such as pollen, which could be significantly more profitable.

Mitigation activities to reduce emission of agricultural greenhouse gases in Hungary
115-119Views:311Pressure on natural resources and the global environment have been identified as the most important challenges to maintain prosperity and improve environmental care. Agriculture is responsible for only a small proportion of carbon dioxide (CO2) emissions, but the sector is more closely associated with emissions of other greenhouse gases such as methane (CH4) and nitrous oxide (N2O). The global warming potential of agricultural activities defined as greenhouse gas (GHG) emissions in CO2 equivalents is relatively low in Hungary, when calculated per land area. However this difference decline, when a GHG emission is calculated per product unit, as yields are lower then in West European countries. Environmental load caused by agriculture is also low in Hungary, where increasing part of EU resources are used for the long-term preservation of natural resources and for the raising of awareness of sustainable farming. The strength of the environmental situation of Hungary, consist of several elements, such as the rich bio-diversity, the significant size of territories falling under natural protection, the extent and importance of forests and the low environmental load from crop production. Among the weaknesses the nitrate load of the animal husbandry farms, the increasing water and wind erosion, the soil compaction and degradation have to be taken into consideration. Climate change has high risk potential and the mitigation activities of the New Hungary Rural Development Programme (HRDP) are investigated in this paper with the aim to increase mitigation activities in rural area and reduce the causes of climate change.

Human resource aspect of agricultural economy – challenges of demographic change
163-167Views:374Over the past decades, the agrarian policy has tried to contribute to the catching-up of the rural areas with varying dynamism and aid scheme. However, its result is significantly below expectations. Nowadays, the age composition of the population living in rural areas reveals an unfavourable picture; the rate of the elderly, deprived persons and people being inactive from the aspect of employment is high and it is also combined with the low educational levels. The young generations and intellectuals leave the rural areas and, consequently, the rate of the active population continues to grow narrow as well as the proportion of young and skilled employees decreases. As a consequence of changes in the past decades, the rate of agricultural employment has not led to an intensive change but a failing change in extensive direction which lays off jobs. Nowadays, this process also determines the Hungarian rural society. In the sector, the need for employment diminishes as a result of the development in technology and due to the expansion of services sector. The purpose of our study is to present and analyse the human resources of our country’s agriculture by skill level and age group and compare it with the needs of companies, by doing this we try to compare supply and demand. In details, based on secondary data source, we investigate the agricultural labour force and try to confront it with the advertisements of job search portals (three of our job search portals based on our predefined criteria), by which we achieve a current picture of the agricultural human resource circumstances.

IMPACT OF CLIMATE CHANGE ON PEOPLES’ LIVELIHOOD AND LIVESTOCK PRODUCTION IN UGANDA
Views:401Livestock sector in Uganda contributes significantly towards individual household income and food security and even though peoples’ dependance on livestock production for survival in Uganda is a reality, it’s also undeniable that livestock, which provides food and revenue on a worldwide scale, would be vulnerable to the direct or indirect consequences of climate change. Agriculture contributed 24.1% of the Uganda’s GDP in the financial year (FY) 2021–2022 and according to the Uganda bureau of standards (UBOS), agriculture employs over 70% of Uganda's working population. The purpose of this present study was to to evaluate the impact of climate change on peoples’ livelihood and livestock production in Uganda. Bibliometric analysis was the quantitative technique used for reviewing and describing published publications that assisted in evaluating academic works from secondary data obtained on digital databases in the context of this study. The VOS viewer software was used as a tool to perform the co-occurrence analysis, and then to realize the visualization of the impact of climate change on peoples’ livelihood and livestock production in Uganda using articles analysed on platform research with associated references from the Web of Science database. The visualisation highlighted topical areas that reflect the impacts of climate on peoples’ livelihood and livestock such as diseases, drought, coping strategies, greenhouse gases, drought, vulnerability, dry lands, mobility among pastoral communities, low productivity, reduced forage resources, elevated temperature extra all of which negatively affects the economic levels of individuals and the national income from livestock either directly or directly. Conclusively, interventions that are aimed at improving climate smartness in Uganda’s livestock farming communities may have significant food security and income benefits for different livelihoods.

Agricultural policy and rural development
105-112Views:341The Common Agricultural Policy (CAP) is a cornerstone of EU policy relating to rural areas. Initially, it aimed to provide a harmonised framework for maintaining adequate supplies, increasing productivity and ensuring that both consumers and producers received a fair deal in the market. These priorities have shifted to environmental and animal welfare concerns, as well as food safety and security aspects. As a consequence, the CAP has gradually moved from a production-based structure of subsidies to a market-oriented system, integrating standards for food, environment and biodiversity, as well as animal welfare. In 2010, the EU launched an extensive debate on the future of the CAP, as the European Union needs a better tailored, reformed Common Agricultural Policy to answer the challenges of food, growth and jobs in rural areas. The European agriculture must address the expectations of rural society and demands of the market concerning public goods, the environment and climate change. This raises questions of whether the CAP payments in the past have been effective in achieving their objectives and whether direct payments should be continued for supporting agricultural environmental issues.

Vertical price transmission analysis: the case of milk in the Slovak dairy sector
89-96Views:399Testing for nature price transmission and calculating elasticities of price transmission are important areas of research for providing insights into market efficiency issues. Symmetric or asymmetric price transmission has been the subject of considerable attention in agricultural economics. The concept of the price transmission is an important area of the research particularly in relation to the assessment of impact on the welfare of the vertical entities. The main goal of the paper is an analysis of the price transmission and its exploitation in case of price elasticity estimation in dairy sector. Work investigates vertical price transmission of milk in the Slovak agri-food chain. The research is based on Vector Error Correction Model (VECM) of the selected commodities at producer, processor and consumer level and the estimation of the parameters specified in the model. Moreover the paper determines the coefficient of elasticity of price transmission (EPT).

Farmers’ knowledge on fall armyworm (spodoptera frugiperda) pesticide application and its relationship with quantity of maize that is lost to fall armyworm
Views:336Fall armyworm (Spodoptera frugiperda) has spread rapidly and posed numerous threats to the food security and livelihood of millions of smallholder farmers in Ghana. This study quantifies the damages of fall armyworm infestation in maize production and identifies the various methods used in controlling fall armyworm infestation. Almost all farmers 94% experienced fall armyworm infestation on their farms. They cited key common visual damages as yellowish leaves, stunted growth, poor yield quality, holes in leaves, and egg masses on leaves. Farmer’s loss an average of GH¢2616.07 to fall armyworm infestation. Pesticide application is the frequent control measure mostly used by farmers. Farmers do not mostly use biological methods for the control of the fall armyworm. The use of pesticide as a control method is however not effective as about GH¢ 3 000 per 1 acre is lost with the use of insecticides. It is recommended that the use of other control measures like the contemporary measures involving the use of birds and chickens as predators of eggs and worms of fall armyworm should be encouraged.

Total Quality Management in the food industry – Current situation and potential in Germany
83-87Views:673The requirements in terms of information availability, risk precaution and control in the food industry continue to increase. In this context the interest of companies in the Total Quality Management (TQM) approach is also increasing. This development attracts notice to Business Excellence and connected systems. Similarly, various quality management tools and techniques are available. In this regard a research project analyzed to what extent the companies in the food industry apply different activities of the TQM scheme. The research calculates the importance that the companies attach to different requirements of TQM and how they implement them. Additionally, statistical analysis provides evidence that there is a positive correlation between the implementation of the activities of TQM and the medium- to longterm success of a company. In this article the methodology and major findings of this research project are presented.

CAP 2013 reform: consistency between agricultural challenges and measures
47-55Views:416The latest reform of the Common Agricultural Policy has just been accepted, identifying important challenges for EU agriculture but proposing only limited changes to the previous CAP. Now it is time for the implementation of the new measures. However, from a theoretical point of view, it seems that the CAP can hardly meet the challenges it faces due to the inconsistencies between the predefined challenges and the measures proposed to meet them. The aim of the paper is to analyse the consistency between the challenges of European agriculture and the policy measures aimed at meeting them. It seems that not all measures are consistent with the challenges.

Development of commodity exchange in Croatia
87-89Views:269Purpose of this thesis work is to show relevance and necessarity for existing of commodity exchange and it’s influence to the economy of Croatia. Because eastern part of Croatia, region called Slavonia is mostly agricultural oriented, it is of essential relevance to establish and make operate of first commodity exchange in Croatia. Widely in the past, while Croatia was part of Austrian – Hungarian kingdom, first commodity exchange in Europe that was established in 1853. in Budapest, practically was domestic commodity exchange for Croatian business subjects, and they were able to use benefits it brought. Me personally, and a lot of other business people and business society in Croatia belive that time to reasteblish commodity exchange has come. In this thesis, I will give a deeper look in to commodity exchange, describe acctual situation in Croatia, show posibillities that commodity exchange brings, how it works and what has to be done to implement commodity exchange and benefits it will bring to Croatian economy.

The role of trust in cooperation between farmers – the outcomes of a survey in Békés county
103-112Views:426Local socio-economic cooperation arrangements can contribute to the development of adequate solutions which can compensate the negative impacts of globalization. One of the specific areas is agriculture. Capital-intensive technology is the key element in the competitiveness and viability of firms. The present paper reviews the factors affecting the joint machine use arrangements of agricultural producers, with special regard to the role of trust. The questions of trust are examined in two dimensions: contractual and competence trust. On the basis of the survey carried out among farmers a positive connection was detected between the level of trust and the farmers’ activity in cooperation arrangements. Our results also pointed out that the trust needed in different areas of cooperation is very different. The experiences indicate a tendency, according to which contractual trust is more important in intensive cooperation arrangements which result in higher dependence, while competency trust is more emphasized in more extensive solutions.

THE ROLE OF TRADITIONAL FARM RISK MANAGEMENT STRATEGIES ON REDUCING CREDIT RISK IN TANZANIA AGRICULTURAL LENDING
Views:143Agricultural financing enhances food security, job creation, a transition from subsistence to commerce farming, and strengthens the overall economy. However, due to unfavorable weather and market conditions there is limited financing directed towards agriculture especially in developing countries. Despite smallholder farmers' high adoption rate of traditional risk management strategies to minimize these risks, little has been done to examine its moderating role on the relationship between agricultural risks and credit risks. Thus, this study examines the role of farm business risk management strategies on minimizing the influences of production and market risk on smallholder farmers loan repayment capacity. The quantitative study used pooled cross-sectional data from a Tanzanian commercial bank from 2019 to 2021, covering 1,277 smallholder farmers from different administrative regions. Using binary interaction effect logistic regression analysis model, the study's results indicate that irrigation, mechanization, and off-farm diversification significantly minimizes the effects of production and market risk amongst smallholder farmers in Tanzania, an indication that traditional risk management strategies are effective tools amongst smallholder farmers. On the contrary, on-farm diversification strengthens the influence of production and market risk on loan repayment amongst the smallholder farmers in Tanzania, the results that can be influenced by a number of factors, including poor diversification knowledge among smallholder farmers. In light of these findings, the study recommends that policy makers and other development partners to develop agricultural infrastructure and provide more extension agents that can educate smallholder farmers on the best practices on traditional risk management.

The influence of employment modes on employee turnover and agri-business performance: a case for Hunyani farm in the Zvimba district, Zimbabwe
17-27Views:477The labour intensive nature of Zimbabwean agriculture demands that farmers meet excessive labour requirements, at the same time keeping labour costs as low as possible to guarantee profits and achieve maximum business performance. This study, carried through a questionnaire survey, at the Hunyani Matura Farm, in the Zvimba district of Zimbabwe between from October 2017 to March 2018, investigated the effect of employment mode on turnover and agri-business performance. Data collected from the participants, was compared with the information from secondary source documents. From the results temporary workers performed better than permanent workers and they cited problems of low wages, poor working conditions, high work targets, inequality in work allocation, job insecurity and constant shuffling. Temporary workers had higher turnover and turnover intentions than permanent workers. Temporary employment mode had a positive
effect on agri-business performance. This study recommends the use of permanent employment mode on key positions like forepersons, stores persons and supervisors, and temporary employment mode on general farm tasks, while seasonal contracts were seen good for skill demanding operations such as tobacco seedbed establishment, tobacco reaping and curing and grading. A ccareful selection of employment modes reduces inequalities and unhealthy attitudes at work and improves on farm business performance.JEL Classification: Q12

Potential for Hungarian Grasslands in integrated rural development
37-39Views:292Sustainability and multifunctionality, two key principles, which will determine future development in any activities. On the bases of these principles, society as a whole has already outlined future expectations towards rural areas. Rural functions (economic, ecological and socio-cultural ones) have been declared in European Charter for RuralAreas. To what extend can different rural development initiatives meet these functions? The question may be answered by using the method of multifunctional rural resource analysis (NAGY, 2007). The paper is investigating the potential for Hungarian grasslands by using this methodology. It is concluded that our grasslands, as land use systems in their present conditions can participate in integrated rural development in the most balanced way compared to other land use systems in the county. Economically their potential is good. Ecologically their potential is outstanding. The socio-cultural potential of grassland use in Hungary is also outstanding due to the historical roots.As a future prediction the relative importance of the three grassland functions has been outlined in integrated agriculture and rural development.

Moderating Influence of Training and Development on Entrepreneurial Performance
47-54Views:330This study assessed the moderating effect of training and development on entrepreneurial performance of Micro, Small and Medium Enterprises (MSMEs) in Nigeria considering the Bank of Industry and Small and Medium Enterprises Development Agency of Nigeria (SMEDAN). Two hypotheses were tested in this study reflecting training and development in Nigeria and Ethical practices of Training and Development impacts on behavioral outcomes of entrepreneurs. The paper puts to test, the preceding assertions with the aid of Kruskal Wallis test. From the test, the study refutes the former assertions on the reasoning that P-values were less than 5% level of significance. This showed that the impact of ethical training and development would be more significant if the young entrepreneurs had earlier exposure from secondary to tertiary education level to make better entrepreneurs in Nigeria. The study observed that the Nigerian educational system has contributed positively to the area of training and development which has enhanced entrepreneurial performance in Nigeria. The study recommends that training and development programme should focus on developing creative or innovative individuals who can help to move the nation forward. A Self-reliant person is a creative individual.

The situation of agricultural sector in Hungary – trends and territorial aspects
Views:515Based on its geographical features, Hungary is basically an agricultural country. The proportion of the production area within the total area of the country is approximately 80% and the proportion of arable land is 60%. This makes our country one of the first in the European Union. In the EU, only Denmark and the United Kingdom have a higher proportion of agricultural land. Hungary accounts for only 3% of the total agricultural area of the EU-27 Member States, however, it plays a significant role in the production of certain products. (Harangi-Rákos, 2013)
In addition, the climate is favorable for agricultural production, which also strengthens the country's agricultural character. Throughout history, we have rightly been given the honorable name “pantry” (Marosi, 2009), which was true both within the Monarchy and Europe. In the socialist system the agricultural country became a so-called “industrial-agrarian” country due to the violent industrializations.
Beyond industrial development, the service sector plays an important role in the national economy due to its technology-intensive nature. In addition, agricultural production is still significant in Hungary (Lakner et al. 2020). The agricultural sector is significantly involved in the production of the gross domestic product (Fróna-Kőmíves 2019) and in the positive development of the export-import balance. During the 2008 world crisis, it was thanks to this sector, among other factors, that the recession that affected our country did not deepen. The domestic consumption is largely covered by domestically produced commodities (Csatáriné, 2019)

Analysis of economic issues relating to the dairy sector, with emphasis on price transmission
61-70Views:336The dramatic decline in consumption after 1990 was an important problem during the analysis of the sector. Even today, consumption is still below the degree that was before the political change, and significantly lags behind the EU level.The importance of this topic is emphasized by the fact that surplus milk could be marketed through the increased domestic consumption; this would create a more stable and calculable situation for farmers. Therefore, I considered it important to reveal what factors and by what shares influence the consumption of milk and dairy products. The relationship, time series and cross-sectional analysis based on national and international databases demonstrate the relationship between the consumption of milk and dairy products and the other determining factors of consumption in Hungary and in the EU-25 through diagrams. I draw the conclusion that there is a medium correlation between the development of the economy, the higher income level and the consumption of milk and dairy products. Just before our EU accession, the dairy sector was one of the most critical industries of Hungarian agriculture, which is why I chose this for my analysis. I regard as a new scientific result the econometric analysis of the asymmetric market conditions in the price transmission approach within our dairy sector between 1995 and 2003. I confirmed and quantified that the market is under an oligopoly and defined the direction of price adjustment. Furthermore, I regard as a new result in the price transmission analysis (also published in the article published with Dr. József Tóth), that the three possible dimensions (elasticity, a symmetry relations,lag) are analysed simultaneously.Therefore,a more sophisticated picture is given on price transmission. The theoretical advantages and disadvantages are verified by an example of a vertical coordination based on the horizontal cooperation in the dairy sector (Alföldi Tej Ltd).

Economic aspects of an agricultural innovation – precision crop production
51-57Views:472Innovation in agriculture ensures the wide-spread use of the latest, up-to-date technology. Such new technology is precision farming in crop production, which serves as a validation of the criteria of environmental and economic sustainability. The economic applicability of precision crop production depends on several factors.Among them the following aspects must be emphasized: the size of the farm, the characteristics of the production structure, the current input-output prices and their tendencies, the investment needed for transitioning to precision technology and its capital source, the level of professional knowledge and the managerial attitudes of the farm. I have examined the economic relations between potential savings in chemicals on EU level. It has been found that after switching to precision farming, the active ingredient use for fertilizers can be reduced by 340 thousand tons at the same expected yield level in an optimistic scenario in the EU-27, while the savings in pesticide use can be 30 thousand tons (calculating with the current dose-level). If approximately 30% of the crop producing and mixed farms over 16 ESU adopt this new technology, this will diminish environmental loads by up to 10-35%. The majority of farms characterized by greater output and size can be based on their own equipment but it might as well be presumed that smaller farms can turn to precision farming not based on their own investment. They can buy the technical service from providers, they can establish producer cooperation, for example in the frame of machinery rings. At a certain farm size and farming intensity precision crop production is a real, environmentally friendly farming strategy, with the help of which the farm can reach earnings that cover at least the economic conditions of simple reproduction.

ICT and agritourism in Czech Republic
45-48Views:335Tourism is regarded as the world’s future. Agritourism is a unique symbiosis of agriculture and tourism. Based on extensive analysis of the state agritourism in the Czech Republic, it was found that information on agritourism facilities is very diverse and disorderly, lacking a specializedportalforagro-tourism. Agritourism facilities in th eCzech Republic is several thousand, but most of them have non-quality websites, or none at all. It should been sured that entrepreneurs in the agritourism (farmers) had knowledge easily and with minimum cost to present their own small farm on the web, such as using Web content management system (WCMS). It is proposed the new portal solution, which according to the principles ofWeb 2.0 will provide greater information sharing among the partners in the field of agri-tourism.

Research on the natural features of karst water, on the example of some water intakes
63-67Views:278The existence of safe and abundant raw water sources is a priceless treasure for any country. Water resources are of particular importance for Montenegro, especially for the development of tourism and agriculture which represent the backbone of its economic development. With respect to water potential, Montenegro is at the top of Europe. However, it is not a sufficient factor, but the very way it is used and protected, as well as the improvement of its valorization. Economic development which is not based on the conservation and good governance of natural resources may have negative consequences for the overall development. The aim of the paper is the study of natural properties of karst ground waters and their changes through interrelation of some ions, as indicators, on the example of five intakes in use. The paper presents the results of the research on the said waters and the values of indicators which point to their exceptional benefits for the water supply. However, the effects of the anthropogenic factor are evident, which are reflected in the range of the mole ratio of Ca /Mg ions ranging from 5.4 to 9.6, and the values (eqv.SO4/Cl) ranging from 0.3 to 2.0. Protection of the environment, especially preservation of the quality of water resources of Montenegro, imposes the urgency of implementation of the objectives of the Water Framework Directive.

Protected geographical indication recognition and willingness to pay: A case of grojec apple
73-80Views:414The Grojec region of Poland is an important region for apple production and accounts for 40 percent of domestic apple production. Apple growers from the region made an attempt to strengthen their competitive position through registering their apples as Protected Geographical Indication (PGI) products. The European Commission’s PGI allows food producers to obtain market recognition and a premium price for their products. Although the Grojec Apple received PGI registration in 2011, little has been done to promote apples with the PGI label. Two important research questions are addressed: 1) Does the Polish market recognize Grojec Apple PGI, and 2) Does the market value Grojec Apple PGI? Logit and regression models are estimated using survey data collected during an International MBA in Agribusiness and Commerce study week in Warsaw. Only 22% of consumers recognize Grojec Apple PGI. Yet, 70% of consumers indicate they are willing to pay more for the product and their average willingness to pay (WTP) premium is 32%. Results indicate use of the PGI label may be effective in improving sales and profit margins for Grojec Apple producers and their affiliated cooperatives. Older consumers are more likely to indicate a WTP premium. Males, smaller households, and consumers less sensitive to apple price indicate a higher WTP premium. An advertising campaign promoting Grojec Apple PGI as a better product may be effective at increasing consumer likelihood to pay more and WTP premium. Although “Grojec” is already familiar to most consumers in central Poland as a region for apples, a Grojec Apple with PGI label would assure consumers they are purchasing apples from the Grojec region and the apples are high quality.
