AbstractThis paper describes the complex hydrogeological, legal framework and socioeconomic costs of the groundwater protection in major groundwater basins (MGBs) in Poland in accordance with European directives. The hydrogeological criteria developed in Poland for establishing MGBs and the principles of their protection provide more details to the directives that are in force in Europe, which define the general principles for groundwater protection. The procedure of establishing MGB protection zones is connected with a change in local plans and land development and requires an analysis of the cost–benefit relationship in the sphere of social economy in the sector of public economics. The cost assessment was performed on the basis of data from hydrogeological documentations, and the aggregation of subareas to which the same existing and planned development can be attributed. A legal analysis of bans, orders and restrictions together with the identification of the risk of claims in specific hydrogeological and development conditions was a fundamental issue of research. These costs depend on the acreage and land use of the protected area. The unit costs of MGB protection, calculated per 1 km2 of the protection area, for six sample basins were estimated at €120 to €208,000/2 years/1 km2. The highest costs are generated by establishing protection in urban areas, while the lowest costs are generated in forest areas.

Большое значение в увеличении продуктивности картофеля имеет внедрение в производство перспективных высокоурожайных сортов и гибридов, приспособленных к местным природно-климатическим условиям возделывания, от чего зависят эффективность отрасли и себестоимость продукции. Цель работы – изучить влияние климатических условий на продуктивность и качественные показатели сортов и гибридов картофеля, а также использование ими благоприятных почвенно-климатических условий высокогорья Республики Дагестан, для размножения и внедрения в производство новых перспективных, высокоурожайных, приспособленных к условиям среды выращивания сортов картофеля с комплексом хозяйственно-ценных признаков. Объектом изучения послужили сорта картофеля раннего, среднераннего и среднего сроков созревания российской, белорусской и иностранной селекции. Полевые опыты закладывали в 2014–2017 годах на высоте 2000–2200 м, на землях горного опорного пункта «Курахский» Курахского района и на равнинной провинции (Прикаспийской низменности) на территории дачного массива «Наука» Махачкалинского района Республики Дагестан. Схема посадки – 70×30 см, повторность – четырехкратная. Технология выращивания картофеля – гребневая. При проведении полевых опытов использовали общепринятые методики. Практически все сорта картофеля, выращенные на равнинной провинции, сформировали высокий урожай в первый год и при дальнейшем размножении в результате развития вирусных болезней резко снизили свои продуктивные качества. Наиболее высокая урожайность в среднем за три года отмечена у сортов Жуковский ранний (20,8 т/га), Импала (20,5 т/га), Невский (17,8 т/га), Предгорный (16,9 т/га) и Удача (16,3 т/га). В свою очередь, горная провинция Дагестана характеризовалась благоприятными почвенно-климатическими условиями для возделывания как продовольственного картофеля, так и для организации первичного семеноводства на безвирусной основе и размножения перспективных сортов этой культуры. В среднем за годы исследований в горной провинции по урожайности выделились сорта Сильвана (37,4 т/га), Удача (37,6 т/га), Рокко (33,3 т/га), Импала (31,7 т/га), Жуковский ранний (29,0 т/га), Предгорный (27,7 т/га) и Примобелла (27,7 т/га), а также гибриды № 12.40/17 (43,1 т/га) и № 13.61/61 (38,8 т/га). The introduction of promising high-yielding varieties and hybrids adapted to the local natural and climatic conditions of cultivation is of great importance in increasing the productivity of potatoes, which determines the efficiency of the industry and the cost of production. The aim of the work is to study the influence of climatic conditions on the productivity and quality indicators of potato varieties and hybrids, as well as their use of favorable soil and climatic conditions in the highlands of the Republic of Dagestan, for breeding and introducing into production new promising, high-yielding, adapted to the growing environment of potato varieties with a complex of economically valuable characteristics. The object of the study was potato varieties of early, mid-early and medium maturation periods of Russian, Belarusian and foreign selection. Field experiments were conducted in 2014–2017 at an altitude of 2000–2200 m, on the lands of the mountain stronghold Kurakhsky of the Kukhar district and on the plain province (the Caspian lowland) on the territory of the suburban area Nauka of the Makhachkala district of the Republic of Dagestan. The landing scheme is 70×30 cm, the repeatability is four times. The technology of growing potatoes is combed. When conducting field experiments, generally accepted methods were used. Almost all potato varieties grown in the lowland province formed a high yield in the first year and, with further propagation, as a result of the development of viral diseases, sharply reduced their productive qualities. The highest yield on average for three years was observed in the varieties Zhukovskiy ranniy (20.8 t/ha), Impala (20.5 t/ha), Nevsky (17.8 t/ha), Predgornyy (16.9 t/ha) and Udacha (16.3 t/ha). In turn, the mountain province of Dagestan was characterized by favorable soil and climatic conditions for the cultivation of both food potatoes, and for the organization of primary seed production on a virus-free basis and the reproduction of promising varieties of this crop. On average, over the years of research in the mountain province, the varieties Silvana (37.4 t/ha), Udacha (37.6 t/ha), Rocco (33.3 t/ha), Impala (31.7 t/ha), Zhukovskiy ranniy (29.0 t/ha), Predgornyy (27.7 t/ha) and Primobella (27.7 t/ha), as well as hybrids No.12.40/17 (43.1 t/ha) and No.13.61/61 (38.8 t/ha) were distinguished by yield.

Solar energy is widely used in solar systems, where economy and ecology are combined. Namely, this represents an important moment in the era of depletion of energy resources. The use of solar energy is a promising economical item for all countries of the world, meeting their interests also in terms of energy independence, thanks to which it is confidently gaining a stable position in the global energy sector. The cost of heat obtained through the use of solar installations largely depends on the radiation and climatic conditions of the area where the solar installation is used. The climatic conditions of our country, especially the south, make it possible to use the energy of the Sun to cover a significant part of the need for heat. A decrease in the reserves of fossil fuel and its rise in price have led to the development of optimal technical solutions, efficiency and economic feasibility of using solar installations. And today this is no longer an idle curiosity, but a conscious desire of homeowners to save not only their financial budget, but also health, which is possible only with the use of alternative energy sources, such as: double-circuit solar installations, geothermal heat pumps (HP), wind power generators. The problem is especially acute in the heat supply of housing and communal services (HCS), where the cost of fuel for heat production is several times higher than the cost of electricity. The main disadvantages of centralized heat supply sources are low energy, economic and environmental efficiency. And high transport tariffs for the delivery of energy carriers and frequent accidents on heating mains exacerbate the negative factors inherent in traditional district heating. One of the most effective energy-saving methods that make it possible to save fossil fuel, reduce environmental pollution, and meet the needs of consumers in process heat is the use of heat pump technologies for heat production.

Currently, to increase the efficiency of industrial production, high-performance and expensive technological equipment is increasingly used, in which the weakest link, from the point of view of efficiency and reliability, is the components and parts of heavily loaded tribo – couplings operating both at significantly different temperatures (conditionally under lighter conditions, the temperature difference can be 100-120 degrees) and climatic conditions (high humidity, the presence of abrasives and other chemical elements in the atmosphere). As the results of the analysis of the frequency of failures of friction units and, accordingly, the cost of their restoration reach 9-20 percent of the cost of all equipment, without taking into account significant losses of income (profit) of the enterprise from downtime. The solution of this problem is based on the study of the wear rate of friction units by the wear products accumulated in working oils, cooling lubricants, and greases. A digital equipment monitoring system (DSMT) has been developed and implemented, which includes dynamic recording of the number of wear products and oil temperature by original modern recording devices, followed by the technology of their processing and use. The system also includes methods for finding the necessary information in large data sets useful and necessary in theoretical and practical terms with a similar technique controlled by a digital monitoring system. The advantages of SMT are the ability to predict the reliability of the equipment; reduce production risks and significantly reduce inefficient costs.

The economic efficiency of the cultivation of grapes as a branch of agriculture depends on the adaptation of grape varieties to the soil and climatic conditions of the place of growth. When developing new agricultural practices and technological solutions for the cultivation of grapes, it is necessary to assess the econom-ic efficiency of the proposed innovative ap-proaches. The cultivation of such grape varie-ties is becoming important and relevant, which, with high productivity and the use of differen-tiated care technology, require minimal costs when servicing the bushes and harvesting. In-creasing labor productivity in the viticulture industry is the most important condition for the intensive development of production. One of these conditions today is the formation of a bush according to the technology element, the shape of a bush AZOS-1, which allows to re-duce the cost of care and harvesting of grapes. The conducted research on the technology of cultivation of table grape varieties in connec-tion with the use of a new form of bush made it possible to economically substantiate the economic efficiency of growing grapes.

The purpose of the article is to assess the pace of capital contribution and investment in solar energy in order to increase the energy security of national economies. The study analyzes the development of the global solar industry for years 2009-2019 in the context of investment support. The main stages of development of world solar energy are marked and the priority of countries and regions is determined. Factors of attractiveness of solar energy for private investment are noted, namely the investment climate is formed at the expense of legislative maintenance of this sphere, and in the economic plan at the expense of introduction of the «green» tariff. Two main investment processes in the development of solar energy are noted. First, these are large private companies that implement large-scale projects from solar stations. Secondly, this small private investment to provide electric for households that identified a small city urbanization and climatic conditions. It was found that the solar energy market depends more on capital intensity than on resource intensity. The result of economic calculation is indicated, which allowed to determine the term of reduction of the cost price of 1 kW of photovoltaic power station electricity to the level of NPP production cost for ten years.

Currently, the modern poultry farms are located in regions with different climatic conditions. Thus, the component of the electric power being the base for combined heating and ventilating systems, lighting, and local heating of poultry farms, is great in power engineering on the territory of the Russian Federation. The analysis of energy costs of poultry farms showed that of the estimated options for reducing the cost of electricity for poultry farms, one of the most effective can be an alternative source such as the generation of own electricity. Naturally, for biological production with a continuous technological cycle (poultry farming, for example), seems to be replace about 45-55 % of the needs of the factory and serve as a reserve for the rest, but not cover all 100 % of needs.
