Aviation is one of the most significant growth drivers not only for the transportation infrastructure, but also for country’s economy as it contributes to both industrial and social progress of society. The paper focuses on Sheremetyevo International Airport, one of the largest Russian airports and analyzes it in terms of short-term and long-term perspectives. Using real statistical data, the article presents the models for forecasting essential performance indicators of airports, namely, passenger traffic and revenue. By comparing quality characteristics, most suitable models were selected and checked for adequacy. Forecasts of the probable changes in the values of the performance indicators were made under the assumption of maintaining the previously formed development trend.

A promising route to transition wastewater treatment facilities (WWTFs) from energy-consuming to net energy-positive is to retrofit existing facilities with process modifications, residual biosolid upcycling, and effluent thermal energy recovery. This study assesses the economics and life cycle environmental impacts of three proposed retrofits of WWTFs that consider thermochemical conversion technologies, namely, hydrothermal liquefaction, slow pyrolysis, and fast pyrolysis, along with advanced bioreactors. The results are in turn compared to the reference design, showing the retrofitting design with hydrothermal liquefaction, and an up-flow anaerobic sludge blanket has the highest net present value (NPV) of $177.36MM over a 20-year plant lifetime despite 15% higher annual production costs than the reference design. According to the ReCiPe method, chlorination is identified as the major contributor for most impact categories in all cases. There are several uncertainties embedded in the techno-economic analysis and life cycle assessment, including the discount rate, capital investment, sewer rate, and prices of main products; among which, the price of biochar presents the widest variation from $50 to $1900/t. Sensitivity analyses reveal that the variation of discount rates causes the most significant changes in NPVs. The impact of the biochar price is more pronounced in the slow pyrolysis-based pathway compared to the fast pyrolysis since biochar is the main product of slow pyrolysis.

SummaryThe German government has adopted a law that requires sewage plants to go beyond the recovery of phosphorus from wastewater and to promote recycling. We argue that there is no physical global short‐ or mid‐term phosphorus scarcity. However, we also argue that there are legitimate reasons for policies such as those of Germany, including: precaution as a way to ensure future generations’ long‐term supply security, promotion of technologies for closed‐loop economics in a promising stage of technology development, and decrease in the current supply risk with a new resource pool.

Abstract Rare earth permanent magnets are important components for modern (energy) technologies and are employed to reduce GHG emissions and combat climate change. The process of extracting these minerals from the ore has contentious economic, environmental and social implications. While the environmental impacts of their production have already been analyzed in several studies, the economic and the social perspective is still under-researched. The Social Life Cycle Assessment (S-LCA) approach employed in the present research explores whether there is a difference in social risks for rare earth permanent magnet production from three different rare earth ore production locations and the associated value chains. While one is located completely in China, another is composed of processes in Australia and Malaysia. The third process chain combines processes in the United States and Japan. The Product Social Impact Life Cycle Assessment (PSILCA) 2.0 database is used to assess the social implications. The analysis focuses on value chain actors, a stakeholder group of great interest to businesses but often underrepresented in S-LCA research. The impact categories describing this stakeholder group pertain to issues of social responsibility along the value chain, fair competition and corruption. Overall, the US value chain indicates the lowest level of social risk along the supply chain. However, in order to gain a deeper understanding of the social risks a sectoral and geographical analysis is conducted. Across all three cases, the mineral, fossil fuel and chemical sectors are shown to be problematic.

AbstractIncreasing resource scarcity and what has been called “the end of cheap nature” are prompting policymakers and scholars to foster more circular economies to reduce waste and lengthen the lifespan of material goods. Our essay critically examines the political and economic relationships between urban and rural geographies in the context of secondhand economies. Practices of bartering, swapping, selling, and repairing used goods have long been important to rural people and places, but the increasing commodification of discards risks upending rural livelihoods and ways of being as goods move toward urban centers. We explore the relationship between rural and urban reuse economies and suggest how future scholars of rural North America might contribute to strengthening and supporting localized reuse practices.

The Asia-Pacific region has the most rapidly growing energy demand in the world and will continue to have an increasing impact on world energy demand. Given the heterogeneity of economies in the region, any regional demand analysis has to be constructed country by country. In undertaking the demand forecasts provided in this study, scenarios were developed for high, low, and base cases that take into account variations in economic performance, prices, and fuel substitution in individual nations and in the region as a whole. China is included in the aggregate regional data provided in this article. Data from the countries of the former Soviet Union are not included in the regional totals in this article and are discussed separately in article 4.

The oil production and refining processes are directly dependent on historical and political processes. The world wars of the 20th century were catalysts for the transformation of oil as the main energy resource. The capacity of enterprises in the oil refining industry is important for the development of politics and economies of states because oil products are one of the most sought after goods. Addressing the problem of capacity development for oil resource processing at Russian refineries is a relevant topic to build an effective policy for the distribution of global oil resources. The purpose of this paper is to identify the distribution trends in oil resource refining capacities in Russia. The developed method allows us to determine the dynamics of refining capacities in all regions of the country, establish the contributions of refinery groups to regional and countrywide capacities, and identify trends in the capacity concentrations of refineries and regions. The timeline that was used for the research period is 2009–2019. The results of the study showed increases in processing capacity in all federal districts. By 2019, the Volga Federal District provided the largest annual contribution to the countrywide capacity. The Southern Federal District moved up from the fourth to second position. It was followed by the Siberian, Central, Northwestern, Far Eastern, and Ural Federal Districts. The trends in the distribution capacities across the country indicate the prospect for building additional refineries in the Asian part of Russia. Rosneft was the leader, while Gazprom retained the second position. Independent refiners took the third position in terms of total refinery capacity, with Lukoil in the fourth position. Furthermore, Surgut-NG, Tatneft, Mini refineries, and NOVATEK followed the top four positions. The changes in concentration ratios indicated the increased monopolization of the refinery market. A decisive contribution to this process was due to by Rosneft’s takeover of TNK-BP and Bashneft’s capacities. The changes in regional concentrations were influenced by the changes in processing capacities of the Volga Federal District.

This article describes the process of business activity organization on the regional level and possible influence that external factors cause on it. It is stated that in the years 2010-2016 the number of economic entities in Ukraine has slightly decreased. It is concluded that the share of all the types of enterprises is similar in Ukraine comparing with the EU averages, although there is a significant deviation in the indices of businesses by 10 thousand population which in Ukraine are less than the average for EU countries. In the process of researching the state of development of business activity and the problems of SME development are being indicated. The problems include the following: lack of business support programs at the national level; inconsistency of bank lending to the requirements of business (high interest rates); insufficient infrastructure to support business; unsatisfactory state of vocational training; lack of seed capital for business creation; lack of working capital for business development. It’s concluded that the business model of any business activity plays the role of a template in the process of creation and operation of business in the certain circumstances. It also is an important step in the strategic planning, which includes an overview of future business that in turn affects the evaluation of the main keys of success of the enterprise and determines its growth. The model of business creation is relatively based on resource approach, which is concentrated on the resources and capabilities of the enterprise and is the most important for determining strategic actions. In the perfect circumstances the resources for business activity are meant to become the part of the process of business creation and development. They may be helpful not only as route map of the project implementing but also as its main part. The issue of developing the set of measures that provide the specific tasks of development and activity of small and medium enterprises at the regional level that will ensure efficient use of any information and implementation of scientific approach in business was further developed. The measures mentioned include: implementing the support of entrepreneurship; microcredit funding of the SMEs; increasing the number of small and medium-sized businesses in the production and others. The article also states that business is entirely dependent on the state system concept. The set of measures that provide specific tasks of development and activity of small and medium enterprises (stimulation of entrepreneurship, attracting business in the IT sector, the promotion of export-oriented businesses) should not only solve the economic problems of the country and the region but social issues as well: providing more working places and supporting the small business in the regions. The research and conclusions gained in this article may be used as the theoretical and practical material for government in order to support the SMEs and for entrepreneurs who intend to start their own business.

Actual importance of research theme: Combating hunger and providing the Earth’s population with sufficient amount of products is considered one of the strategic priorities of human civilization sustainable development by the UN up to 2030. The rapid growth of this planet’s human population in the 21st century, estimated at 7.6. billion people, leads to the global demand for production and foodstuff. Simultaneously, traditional strategies of extensive development conventional in the 20th century and “target” intensification of agriculture do not take expected positive effect nowadays. World economy requires for new strategies of agricultural production, as well as promoting ‘green revolution’ based on the ground of IT technology advances and “Industry 4.0.”. The generalization of world experience concerning development and implementing agricultural production strategies in the 21st century is of greater theoretical and practical importance for all countries which export agricultural production in mass scales, including Ukraine which focuses on the leadership in the world agricultural business. Thus, the urgency of the issue confirms the actual importance of this article. The problem statement. Foodstuff output in world economy is growing slowly and does not meet the increasing demand for food and agricultural products in industry in global scales. Under these conditions the manufacturers of agricultural products like farmers, agro-businesses and agro-holdings, as well as transnational corporation alter and modify agricultural strategies that were conventional in the 20th century. Among the new strategies transition to precision farming and innovational agriculture based on implementing IT technologies takes the leading role. The core and socio-economic consequences of such strategy implementation require further study. Analysis of latest studies and publication. The important contribution to the study of the core and dimensions of agricultural production strategies linked to innovation and investment development as well as to improvement property relations is made by such Ukrainian scholars as P. Makarenko, V. Pilyavskiy [1] and O. Shul’ga [2]. Foreign scientists like Smaller, C., andW. Speller, withH. Mirza, N. Bernasconi-Osterwalder, andG. Dixie [3] paid the specific attention to the study of strategic priorities concerning risks minimization and profit maximization by agro-businesses and TNC within the realization of agricultural contracts at world markets. Overseas researchers KeatingB., HerreroM., CarberryP. [4] emphasized on actual importance of compliance with strategy of foodstuff security in global environment in their studies. However, the issue of developing the strategy of precise agricultural production based on widespread use of innovation and IT technologies, research into socio-economic consequences accompanying their implementation in the 21st century remains poorly studied. Research challenge of general issue. The issue of studies the core and elements of agricultural production development process in world economy is highlighted in world economic literature pretty well. Nevertheless, the study of TNCs and agricultural businesses strategies and strategies concerning transition of TNCs to the development of precise agriculture is really meaningful. Besides, at present time the trends of direct foreign investments as for agricultural lands purchase and priorities analysis of their use by TNCs in developed and developing world countries are uncertain. Socio economic consequences of mass precise agriculture introduction for national economy in countries with agrarian specialization also require detailed researching. Problem statement, objective of research. The objective of research is to highlight the core and define the regularity of formation, as well as emphasize the basic expected socio-economic consequences of precise agriculture development strategy implementing on the grounds of generalization the world experience of agricultural TNC sactivity. To achieve the objective set the article aimed at solution the following tasks: to note the main ‘players’ at the world agricultural market and study the priorities of their economic activity; to study the core and the elements of ‘green revolution’ strategy, as well as strategy of transition to precise agricultural production based on implementing innovations and IT technologies; to define strategic goals of TNCs as for the use of acquiring land ( at the cost of direct foreign investments) on the grounds of generalization developed and developing countries experience; to point out the expected socio-economic consequences of mass implementation of precise agricultural production strategies by TNCs and national agro-businesses for the economy of the countries specialized in agriculture. Method and methodology of the study. While studying the world experience of implementation the precise agricultural production development strategies theoretical and empirical methods of scientific research were employed. Historical and logical methods, abstract and specific methods, methods of analysis and synthesis, as well as causal (cause-and-effect) method were applied in the article to define strategic priorities of agricultural business and agricultural TNC specialization, to point out expected socio-economic consequences of mass transition to precise agricultural production in the countries with agrarian specialization. Synergetic approach, method of expert estimates and casual methods were applied to ground “green revolution” strategy, as well as strategy of TNCs as for transition to precise agriculture based on innovations and IT technologies. The results of study. Agricultural production is presented by farmers, households, state agricultural sector, national agro-businesses and agro-holdings, international TNCs. As a rule, farms are focused on domestic market; they specialize in production of minor parties of manual crop production and horticulture, grow vegetables, fruit and berries, as well as they are engaged in poultry farming, beekeeping, dairy production, stockbreeding in rather small scales. The farmers in developed world countries, particularly EU countries, concentrate on organic production which is of high demand among middle-class representatives. In EU countries farming is traditionally supported by the state, as it bears both economic and social valuable functions, i.e. assists in rural development and creates workplaces in countryside. The main stakeholders at the mass agricultural market in the world are considered large national and international agro-holdings an TNCs specialized in agricultural production and its industrial processing. TNCs shaped the closed loop – from selection to agricultural production, from its processing to its manufacturing. At the cost of large production scales, as well as capital concentration and centralization it is the agricultural TNCs which leads in production and export of foodstuffs at world markets. TNCs ‘ leadership at world agriculture markets is grounded on ‘green revolution’ strategy implementing, which consists of such elements as innovations, bio-selection to produce performance breed, intensive growth in crop productivity, including the one using GMO which makes cropping insensitive to water shortage, high temperatures and droughts. Agrarian TNCs in the 21st century actively implement the strategies of transition to precise agriculture based on the use of innovations and IT technologies. As the world experience confirms, strategies of transition to precise agriculture combine the following innovations: astronaut and aviation technologies, unmanned technologies, unmanned aerial vehicles; mass transition to the use of apparatus to analyze the ground online; spreading of “agro-scouting” innovation technologies as for field information gathering concerning the condition and development of agriculture; implementation intellectual system of managerial decision-making support; introduction of monitoring and control auto-system and implementation of IT-system as for account of agriculture process elements. The development of precise agriculture for national world economies which are agriculture-based offers a lot of benefits, such as: increase in labor productivity in agriculture; the decrease in employment that saves working capital of agro-businesses; industrialization and technical renovation of agrarian sector which promotes the market for IT products, precise machine building; increase in commerce and export potential of the country, mainly, in the sphere of monostructural crop production (grain, corn, soya, raps, oilseeds etc.). Such strategies also provide revitalization of direct foreign investment processes by TNCsconcerning purchasing farmland in the developing countries with their further listing as raw materials supplier for TNCs. The latter shape and control international links of production value added to all kinds of agricultural products. Among the risks which implementation of precise agriculture strategies bear for national developing country’s economy which are agriculture-based the following should be mentioned: risks concerning decrease in farms and decline in production of labor-intensive small-scale agriculture products (vegetables, fruit, honey etc.); risks of jobs recession and, respectively, the number of rural population and others. There are also other risks linked to these processes like risks of growing volumes of ready foodstuffs import, chronic scarcity of state budget and increase in internal debt, enhancing migration processes etc. In case of falling world prices for foodstuffs and worsening global conditions for agriculture products, including agrarian raw materials, in particular, due to another world economic crisis, the abandonment of occasional farmland purchased by TNCs in developing agrarian countries, their further freezing and ceasing the processing for better times should not be excluded. Under such circumstances the risks of famine for countries which could lose the managerial control over own land resources are also a threatening exercise as for implementing such TNC strategy. The field of results application. International economic relations and world economy, development of agriculture competitive strategies in world countries and agrarian TNCs in world economy. Conclusions. Farms, agro-businesses, agro-holdings and agrarian TNCs are the economic centres of mass agriculture production in all world countries. Farms are mainly specialized in labour-intensive small-scale agriculture production like horticulture, gardening, bee-keeping etc. Large agro-businesses and agrarian TNCs choose the strategy of specializing in mass monostructural agriculture production such as crop production (grain, corn, soya beans and industrial crops). In developed world countries TNCs apply the strategy of farmlands multi-purpose use, including the goals aimed at development and processing livestock and crop production; at development of renewable energy and bio-energy. In developed world countries TNCs focus on processing all kinds of agriculture products and foodstuffs production with high value added. Purchasing of farmlands by TNCs in developing countries, in particular, at the cost of direct foreign investment, provides for implementation the strategy of purchased lands engagement, mainly, to develop crop production as a raw basis for their further processing in the native countries for TNCs. The general world trend of agrarian TNCs development is use of innovation technologies, transition to precise agriculture based on IT technologies, aviation and astronautic technologies, unmanned aerial vehicles and other innovations which positively impact labor productivity and mass industrial production profitability, as well as choose transition to monostructural agrarian specialization as a priority, but bear a set of social risks for developing countries’ economies. Transition of Ukrainian agro-businesses and agro-holdings to the strategy of precise agriculture development based on innovations and IT technologies provides Ukraine’s competitiveness at the world agrarian markets. This process should go hand-in-hand with land reform taking into account Ukrainian farming interests. Establishing industrial processing of agriculture raw products and production of ready foodstuffs with high value added should be strategic for Ukraine.
