Technical support of producers of agrarian products has always been and will remain a topical issue in realities of agrarian sector of Ukraine. In recent years, integrated forms of agricultural enterprises have become more widespread, which make it possible to increase and renew a machine-tractor park of their participants. In course of study four main technologies of soil cultivation and their impact were considered, an amount of necessary machinery and equipment, energy and labor costs, and impact on quality indicators of soil health. Also, main organizational forms of enterprises that provide equipment rental services or perform fieldwork were analyzed. Proposals were made regarding a merger of existing enterprises into agro technical centers, which would increase an efficiency of their functioning and cover functions of regional self-government. Also, the most common forms of machinery usage by agricultural enterprises were considered.

The aim of the paper is to find out the relationship between beer productions in separate V4 countries. Logarithmic regression analyses with corrected heteroscedasticity and autocorrelation is used to observe the relationship between beer production as dependent variable and independent variables beer consumption, barley and hops yield, imported and exported quantity. All estimated logarithmic regression models are statistically highly significant. Variables without statistical significance are not interpreted. All interpreted variables are inelastic. Except of Czech Republic beer consumption is significant variable in relation to beer production what can suggest export orientation of Czech breweries. Exported beer quantity is significant variable in given model. In Slovakia barley yield is statistically significant but negatively correlated to beer production. In other countries barley and hops yields are not statistically significant. This may mean that these crops are not directly used in domestic beer production. Crops are exported in order to obtain higher added value from side of primary producers. Based on that, beer is mostly produced from intermediate products or imported from other countries.

Consumption and increasing level of living conditions are the main characteristics of society nowadays. Quality of life is necessarily related to living conditions of population, therefore form a basis of sustainable development. The aim of the article is to determine the economic conditions of the population in Visegrad countries (V4) based on the economic indicators of quality of life. The main data source is Eurostat for the period 2005–2017. In the paper is stated and analyzed development of eight indicators of quality of life in the field of material living conditions. They are divided into three groups: indicators on income, consumption and indicators related to the living conditions of the V4 population. The results of the analysis showed that residents of the Czech Republic have the highest quality of life, followed by Slovakia, Poland and Hungary. Position of the Czech Republic and Slovakia among the V4 countries is relatively stable over the reported period. The most significant positive change in several indicators of quality of life was recorded in case of Poland. As for the individual indicators, it was proved in case of Hungary, they had dramatic development without the statistical attributability of their development trend.

Abstract The increase of methane concentration has been established during the last decades. This gas has a relative potential for thermal absorption, 30 times higher than CO2, which means that it is more active in the interaction with the ozone and its blocking. About 70% of the global total emission of methane in the atmosphere is of biogenic origin. Flooded paddy fields are one of the main sources of atmosphere pollutions with methane. Irrigation of rice fields by overflowing reduces the feeding of the ground with oxygen from the air. This in turn affects the fermentation of organic substances in the ground. Methane is the final product in this process. The measurement was performed in the phase of rice earing by an authorized laboratory associated to the Executive Environment Agency at the Ministry of Waters and Environment by means of methods specified by the Ministry. The concentrations of damaging substances were automatically measured at every 60 min for SO2, NO2, NO, and at every 30 min for H2S, CH4, NMHC, CO, and NH3. The obtained results prove that the concentrations of NO, H2S, CH4 and NMHC exceed all limits. The quantity of gases is influenced by the variety peculiarities of the culture (the roots mass, the total bio-mass and the running metabolic processes).

Abstract The current study discusses the role and the importance of alternative food networks, farmers’ markets in particular, for sustainable rural development through the example of Bulgaria. Farmers’ markets are considered as a sustainable business model of networking which encourages production and consumption of local food of healthy origin adhering to high standards for quality and safety, building society and trust and encouraging development of rural regions. The case of Bulgaria is scrutinized in the context of the support for local food and short supply chains anticipated under the national rural development programme for the period 2014–2020 and the current state-of-art and capacities of available farmers’ markets. Some good practices are analyzed and presented establishing a new type of relationships between producers and consumers of farm products proving that farmers’ markets could be efficient incubators of local businesses and new relationships with end-users. Conclusions are made on nature, objectives and functioning of farmers’ markets, challenges and problems in their promotion, support and encouragement.

Abstract Our research deals with environmental pollution, sustainability, and the impacts made by international cosmetic companies on the motivation of purchasing organic cosmetics. Unfortunately, our environment is becoming more and more polluted, which affects our planet Earth on a global scale. It is everybody’s responsibility to decrease the environmental load, diminish our ecological footprint and leave a much cleaner and safer environment to the future generation in line with the principles of sustainable development. We have examined global environmental problems, the efforts made by international cosmetic companies to protect the environment and their impact on the preference, selection and purchase of environmentally friendly cosmetics. Nowadays, efforts of significant importance are prioritised that are more and more shifted to health and environmental consciousness regarding both corporate and consumer behaviour.

Abstract The model of Blue Economy by G. Pauli is inspired by nature. Its main task is to develop innovative methods based on the use of available resources and the use of nature-based solutions. The principle of Blue Economy requires close cooperation of research and development and business activities; and it seeks implementation options in the structure of local economies. Based on the theory known as ‘blue economy’, in order to overcome certain problems of mankind – for example, energy production and consumption –, we must recognize and use some methods given to us by nature. This may be provided to us by new innovations that think according to system theory, that is, occupy the exceptionally effective self-regulating processes of nature in the economy. Methanol may play a key role in succeeding sustainability regarding nature, economy and society. Methanol economy can contribute to reducing human impacts on Earth’s climate by reversing atmospheric carbon dioxide, and it provides the opportunity to get rid of our dependence on dwindling oil and gas resources.

Abstract In the last decades, the area of agricultural land has been declined permanently in Hungary. Despite the diminishing production area, Hungary is among the leaders in terms of the proportion of agricultural land to the total area in the European Union. There are several reasons of using the arable land. As other economic sectors have gained a greater role in the production of GDP and employment, they have taken a larger area from agriculture. Real estate and infrastructure developments were justified by raising the standard of living of the population. The soil, nature, landscape and water protection aspects were also involved. In Hungary, the arable land is the most important natural resource, so it is very important to protect it. In our study, we examine the changes of arable land and uncultivated area in Hungary based on secondary databases of the Hungarian Central Statistical Office and departments of the Ministry of Agriculture. In the course of the research we focused on regional disparities.

Abstract For a long time it has been a well-known and proven fact that economic growth of a country contributes to improvement of the health status of population. There is at the same time another type of opposite relationship starting from health status and pointing to the performance of economy. In our study, besides giving a general presentation of the health situation in Hungary, we examined the direction and strength of the relations between health and economic indicators and the inequalities that can be identified between the different regions with help of statistical methods. Another objective of the study was to examine the factors influencing mortality, and to develop a multiple linear regression equation to estimate the degree of mortality at a confidence interval of 95%. The results could provide a good basis to determine the intervention points necessary to alleviate and improve the economic burden of bad health status and diseases.
