Introduction. The purpose of research is to develop a mathematical model for assessing and forecasting the complex negative impacts of agricultural technologies on water bodies. This problem is relevant because of the need to enlarge agricultural enterprises. The created model for forecasting is necessary to make an objective assessment, taking into account the complex effect of machine technologies applied to agricultural production and all biogenic elements that have a negative impact on water bodies. Materials and Methods. There was used the Spesivtsev – Drozdov method of logical-linguistic modeling, which allows giving expert knowledge a form mathematical model. Four experts were interviewed, and the obtained data became a subject of the regression analysis. The adequacy of the model was confirmed using the coefficient of determination and Fisher’s test. Results. A hierarchical system of 6 factors and 14 sub-factors was formed, including both the applied machine technologies and the management decisions on the matter. There was created a model containing a polynomial equation reflecting the influence of factors on the level of negative impact of technologies and equations that determine the influence of sub-factors on factors. Discussion and Conclusion. The created model can be used for practical purposes to support making decisions for planning, forecasting and selecting scenarios to modernize agricultural enterprises. The model equations make it possible to understand the significance of factors and sub-factors affecting the level of negative impact (diffuse load) on water bodies. This allows us to choose more effective ways to reduce the negative impact by choosing the most significant factors and/or sub-factors as objects of management.

Optimal Decisions

Agriculture is one of the high-risk sectors of the agro-industrial complex, which operates under the influence of internal and external risks. The results of the activities of agricultural producers are directly related not only to the amount and quality of labor, the level of technology and technology used, but also to the objective high risk conditions for agricultural production. Risk research remains one of the most important modern areas of economic research. Risk studies play an important role in predicting economic development and making optimal decisions. Achieving sustainable agricultural production requires research in industry risks. It is necessary to establish a system of organizational and economic measures to reduce the negative impact of risk factors on the production and financial results of agricultural enterprises

The article analyzes modern methods of wastewater treatment from bioresistant pharmaceutical products and biogenic elements. Pharmaceuticals, such as anti-inflammatory drugs, analgesics, antibiotics, narcotic drugs, hormones, drugs that reduce cholesterol,etc., are often get into sewage in small quantities. They are hardly biodegradable and, passing through wastewater treatment plants without any changes, they often end up in water bodies. They have significant negative impact on aquatic ecosystems and human health, while being present in open waters even in small quantities. Among the nutrients that are also present in the wastewater, nitrogen and phosphorus compounds deserve the greatest attention. While getting into water bodies, they cause eutrophication, which isalso dangerous to ecosystems and human beings. It is shown that among modern variety of purification methods, the most suitable for removal of pharmaceutical products and biogenic elements are biochemical methods and photopurification technologies, as well as using membrane bioreactors. Biosorption-membrane methods open the possibility to use modern biotechnologies for efficient removal of bioresistant xenobiotics and reducing their negative impact on natural environment. Using photopurification technologies can help to reduce amount of nutrients discharged in surface water bodies, thus reducing their potential for eutrophication, as well as receiving additional renewable energy sources.

The Impact

The agricultural production, due to the specificity of the functioning of the agricultural industry, is influenced by factors that have significant impacts on agricultural enterprises and determine the importance of state support. The unpredictable factors of agrarian production such as weather, natural disaster, and epidemics increase the risks of agricultural business. That is why farmers need to attract investments. But some farmers do not attract investment because of government subsidies. Besides, using government subsidies could have a negative impact on agrarian business. So, it is necessary to establish the effectiveness of governance for agricultural production and food security in general.

World Industry

At the present stage of development, the entire world industry has faced the problem of rational use of renewable natural resources, in particular the most efficient ways of wastewater treatment and the use of accumulated waste in the production process as a secondary raw material. In particular, the alcohol industry, as one of the components of food, medical, chemical and various industries,leads to the formation of huge amounts of waste, including wastewater. The food industry, like any other industry, has a negative impact on the environment. Water bodies are the most affected by the food industry. Almost the first place in terms of water consumption per unit of production is the production of alcohol. Consumption of large amounts of water leads to the formation of wastewater, which is highly polluted and adversely affects the environment. Due to the high chemical and biological consumption of oxygen, specific color and odor, suspended solids, low pH value, the purification of such waste in the filtration fields and discharge into water bodies is not possible. The purpose of our work is: 1) conducting the analysis of the alcohol industry potential in Ukraine in recent years, and methods of waste disposal as a potential source for the development of bioenergy. 2) environmental aspects of the alcohol industry modernization at present stage of development and implementation of modern wastewater treatment technologies.

Subject. The article considers financial regulation through the use of tax mechanisms. Objectives. The aim of the study is to evaluate European and Ukrainian practices of fiscal incentives for farming through fiscal instruments with VAT playing the key role. Methods. In the study we employed economic and statistical research methods, like monographic, comparison, scientific generalization. Results. Based on the analysis of VAT implementation on farmers in developed countries in Europe we substantiated the conclusion about its focus on simplifying the tax procedures and eliminating the negative impact on operations of economic entities. Special tax treatment (including VAT collection) is mainly used to streamline tax relations, taking into account the specifics of farming, rather than to improve the financial support to farms. We revealed that in the Ukrainian practice its main task is financial support to agricultural production. Conclusions and Relevance. The experience of developed European countries on the use of special tax regimes and taxation procedures should serve as a model for Ukraine. Financial incentives for agricultural production development should be directly supported by the State, and special tax treatment and tax administration should be focused on streamlining tax relations in the region, based on the practice of developed European countries such as UK, Germany, Italy and France.

As a nature-based solution, development of urban blue-green spaces is widely accepted for mitigating the urban heat island (UHI) effect. It is of great significance to determine the main driving factors of the park cool island (PCI) effect for optimizing park layout and achieving a maximum cooling benefit of urban parks. However, there have been obviously controversial conclusions in previous studies due to varied case contexts. This study was conducted in Wuhan, a city with high water coverage, which has significant differences in context with the previous case cities. The PCI intensity and its correlation with park characteristics were investigated based on remote sensing data. The results indicated that 36 out of 40 urban parks expressed a PCI effect, with a PCI intensity of 0.08~7.29 °C. As expected, larger parks with enough width had stronger PCI intensity. An increased density of hardened elements in a park could significantly weaken PCI effect. Noticeably, in this study, water bodies in a park contributed the most to the PCI effect of urban parks, while the vegetated areas showed a negative impact on the PCI intensity. It implied that in a context with higher water coverage, the cooling effect of vegetation was weakened or even masked by water bodies, due to the interaction effect of different variables on PCI intensity.

Today in Russia the main components of digital economy are as follows: electronic trading, public services, export-import activity and constantly developing system of purchasing activity at state enterprises. The system of purchases has to conform to the requirements of modern digital technologies For this purpose at the end of 2018 the President of the Russian Federation proposed to transfer the government and corporate procurement to an electronic form. However, the analysis showed that procurement activities carried out in the form of electronic bidding in agricultural enterprises had a number of problems. These problems are related to the nature of agriculture. For example, seasonality is a key to agricultural performance. In this regard, the system of commercial transactions, including electronic trades, should be as adapted as possible to the peculiarities of agricultural production.
