    Abstract Recharging infrastructure (RI) deployment plays a vital role in improving the public recharging availability for transport electrification. Decarbonizing transportation using low-emission electricity requires massive RI network. Even though the consumers are reluctant to purchase electric vehicles (EVs) until RIs are sufficiently placed, the investors are not willing to invest in RIs due to recharging demand uncertainties. Therefore, a scientific planning framework is needed to ensure the sustainable deployment of EV-RIs in complex networks. In this study, a lifecycle thinking-based multi-period infrastructure-planning framework is proposed to develop sustainable public EV-RIs in an urban context. This framework consists of a temporal model to find the dynamic EV-RI demands, a stochastic model to obtain travel distances, and a multi-objective optimization model to select the best desirable capacities and locations for potential EV-RIs. A case study of a typical medium-scale municipality in Canada was assessed using the proposed framework and validated using conventional infrastructure planning scenarios. The geo-processing data, regional travel behaviors, and recharging characteristics were used as model inputs. The results of the case study showed that the proposed framework can be used to estimate multi-period public recharging demands, minimize lifecycle costs, maximize service coverage and infrastructure utilization, and ensure reasonable paybacks compared to conventional planning approaches. Moreover, this framework can be used to compare different investment assistances, which are required in the early stages of the RI deployment process to encourage investors. Furthermore, government and private institutions can use this framework to identify recharging demands, permitting, and developing RIs in the long-run.

    Abstract The residential sector accounts for most of energy-consumption in developing countries in the form of traditional energy. The use of commercial energy is nominal and confined mostly to urban areas where fuelwood is already monetized. A model, based on an end-use/process analysis approach, is developed on a spreadsheet, which is capable of simulating scenarios to address issues of increasing traditional energy-demand caused by population growth, sustainable supply capacity of the existing energy resources, potential for development of new and renewable energy resources, technology. This paper is divided into two parts: general energy issues and the modelling approach, and the application of this approach to Nepal in the context of fuelwood-supply sustainability.

    Abstract Communication between vehicles and road infrastructure can enable more efficient use of the road network and hence reduce congestion in urban areas. This improvement can be enhanced by distributed control due to its lighter computational load and higher reliability. Despite favourable impacts on traffic, little is known about the effects of such systems on near-road air quality. In this study, an End-To-End (E2E) dynamic distributed routing algorithm in Connected and Automated Vehicles (CAVs) was applied in downtown Toronto, to identify whether benefits to network throughput were associated with lower near-road NO2 concentrations. We observe significant reductions in the emissions of Greenhouse Gases (GHGs) with increased penetration of CAVs. Nonetheless, at times, the emissions of nitrogen oxides (NOx) increased with higher CAVs. Besides, a higher frequency and severity of NO2 hot-spots were observed under a 100% CAV scenario. Impacts of the proposed system on electric energy consumption in a full electric vehicle network were also investigated, indicating that the addition of CAVs that are electric did not contribute to high energy savings. We propose that such new transformative technologies in transportation should be designed with air pollution and public health goals.

    Abstract Conversion of carbon contained in the solid residues (tars + biochar) derived from urban biomass gasification named herein TC would allow enhancing the yield of carbon species (CO/CO2) in synthetic gas. For this purpose, three low cost materials have been tested as possible catalysts: iron species (reduced Fe), bone meal (BM), and ashes (ash) recovered from biochar complete oxidation. The parametric study used the following as variables: air GHSV, onset of reaction temperature, reaction time to optimize CO/CO2 molar ratio and tar content in the produced gas. Results showed an autocatalytic effect of biochar leading to the catalytic conversion of approximately 78% of tars by the native metals contained in TC. The catalytic effect was further enhanced by adding Fe, BM, and extra ash. Addition of Fe catalyst resulted in significant heat generation (temperature increase of ca. 500 °C) and a twofold decrease in reaction time to consume all the carbon. Use of ash and BM as catalysts exhibit heat generation comparable to Fe, along with an improved reaction time, complete tars conversion and a CO/CO2 molar ratio to above 1.3 in the produced gas.

    The assessment of greenhouse gases (GHGs) and air pollutants emitted to and removed from the atmosphere ranks high on international political and scientific agendas. Growing international concern and cooperation regarding the climate change problem have increased the need to consider the uncertainty in inventories of GHG emissions. The approaches to address uncertainty discussed in this special issue reflect attempts to improve national inventories, not only for their own sake but also from a wider, system analytic perspective. They seek to strengthen the usefulness of national emission inventories under a compliance and/or global monitoring and reporting framework. The papers in this special issue demonstrate the benefits of including inventory uncertainty in policy analyses. The issues raised by the authors and featured in their papers, along with the role that uncertainty analysis plays in many of their arguments, highlight the challenges and the importance of dealing with uncertainty. While the Intergovernmental Panel on Climate Change (IPCC) clearly stresses the value of conducting uncertainty analyses and offers guidance on executing them, the arguments made here in favor of performing these studies go well beyond any suggestions made by the IPCC to date. Improving and conducting uncertainty analyses are needed to develop a clear understanding and informed policy. Uncertainty matters and is key to many issues related to inventorying and reducing emissions. Considering uncertainty helps to avoid situations that can create a false sense of certainty or lead to invalid views of subsystems. Dealing proactively with uncertainty allows for the generation of useful knowledge that the international community should have to hand while strengthening the 2015 Paris Agreement, which had been agreed at the 21st Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC). However, considering uncertainty does not come free. Proper treatment of uncertainty is demanding because it forces us to take the step from “simple to complex” and to grasp a holistic system view. Only, thereafter, can we consider potential simplifications. That is, comprehensive treatment of uncertainty does not necessarily offer quick or easy solutions for policymakers. This special issue brings together 13 papers that resulted from the 2015 (4th) International Workshop on Uncertainty in Atmospheric Emissions, in Cracow, Poland. While they deal with many different aspects of the uncertainty in emission estimates, they are guided by the same principal question: “What GHGs shall be verified at what spatio-temporal scale to support conducive legislation at local and national scales, while ensuring effective governance at the global scale?” This question is at the heart of mitigation and adaptation. It requires an understanding of the entire system of GHG sources and sinks, their spatial characteristics and the temporal scales at which they react and interact, the uncertainty (accuracy and/or precision) with which fluxes can be measured, and last but not least, the consequences that follow from all of the aforementioned aspects, for policy actors to frame compliance and/or global monitoring and reporting agreements. This bigger system context serves as a reference for the papers in the special issue, irrespective of their spatio-temporal focus, and is used as a guide for the reader.

    Abstract Reasonable assessment of the environmental benefits of integrating forest products into global value chains (GVCs) is important to promote sustainable development. Based on the forest product sector data for 41 countries from 2002 to 2014, this paper explores the impact of GVC participation on carbon embodied in exports using the 2008 financial crisis, a quasi-natural experiment of negative global value chain shocks. We found that deepening backward participation in forest product value chains led to more substantial increases in carbon emissions than did forward participation. Countries with large decreases in GVC participation reduced more carbon embodied in forest product exports after the financial crisis (relative to countries with small decreases) through a larger reduction in the scale of forest product exports, and a decrease in the growth rate of capital-intensive products as a result of the relative decline in capital investment. They increased the embodied carbon of exports through a decrease in the growth rate of skilled personnel. Strengthening the technology effect of GVCs with the guidance of skilled forestry personnel is a key way to decrease exported embodied carbon.

    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.

    The Chinese government has grown increasingly invested in ecology in recent years. This paper discusses eco-efficiency using data envelopment analysis on 48 cities in Bohai Rim with special focus on the role of industrial structure upgrades. Based on the values from a super undesirable slack-based model, this study investigates eco-efficiency from temporal and spatial perspectives to reveal gaps among Bohai cities but an overall improvement in regional eco-efficiency. Moreover, this study adopts the Global and Local Moran's I to identify positive spatial autocorrelations and shows that most cites in Bohai Rim have high-high, low-low aggregation characteristics. Plus, the economic effects of per capita GDP, industrial structure upgrades on eco-efficiency are determined according to a spatial Durbin model. There appear to be negative spillover effects of industrial structure upgrades on surrounding cities, which reflects an industry transfer phenomenon related to eco-efficiency.

    Authors: Svitlana Bila;

    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.

    Abstract The accumulation of waste biomass and plastic and the inefficient combustion of low-quality coal is a major cause of energy loss and air pollution in rural China. This paper reports for the first time an experimental and multi-perspective analysis on an industrial scale co-pyrolysis of waste biomass and plastic. The results show that the resulting biochar product had a low calorific value of ≥21.0 MJ/kg, which meets the national standard for commercial solid fuel (GB/T 31862–2015). The calorific value of the produced gas was over 10 MJ/m3 and met the requirements of the national standard for residential heating and cooking (GB/T 13612–2006). The products of the co-pyrolysis can replace 1100 t of standard coal per annum, and reduce carbon dioxide emissions, sulfur dioxide emissions, smoke, and other contaminants at the rate of 1720 t, 5–6 t, and 320 kg, respectively, as well as reducing smoke pollution. In addition, through the recycling of 750 t of plastic waste per annum for use in the co-pyrolysis, this method can reduce the white pollution of 50–66.7 km2 of farmland in the local area. The present study can guide the optimization of such systems and lead to adequate flexibility in the co-pyrolysis of different wastes to generate economic and socioenvironmental benefits.

    Abstract Recharging infrastructure (RI) deployment plays a vital role in improving the public recharging availability for transport electrification. Decarbonizing transportation using low-emission electricity requires massive RI network. Even though the consumers are reluctant to purchase electric vehicles (EVs) until RIs are sufficiently placed, the investors are not willing to invest in RIs due to recharging demand uncertainties. Therefore, a scientific planning framework is needed to ensure the sustainable deployment of EV-RIs in complex networks. In this study, a lifecycle thinking-based multi-period infrastructure-planning framework is proposed to develop sustainable public EV-RIs in an urban context. This framework consists of a temporal model to find the dynamic EV-RI demands, a stochastic model to obtain travel distances, and a multi-objective optimization model to select the best desirable capacities and locations for potential EV-RIs. A case study of a typical medium-scale municipality in Canada was assessed using the proposed framework and validated using conventional infrastructure planning scenarios. The geo-processing data, regional travel behaviors, and recharging characteristics were used as model inputs. The results of the case study showed that the proposed framework can be used to estimate multi-period public recharging demands, minimize lifecycle costs, maximize service coverage and infrastructure utilization, and ensure reasonable paybacks compared to conventional planning approaches. Moreover, this framework can be used to compare different investment assistances, which are required in the early stages of the RI deployment process to encourage investors. Furthermore, government and private institutions can use this framework to identify recharging demands, permitting, and developing RIs in the long-run.

    Abstract The residential sector accounts for most of energy-consumption in developing countries in the form of traditional energy. The use of commercial energy is nominal and confined mostly to urban areas where fuelwood is already monetized. A model, based on an end-use/process analysis approach, is developed on a spreadsheet, which is capable of simulating scenarios to address issues of increasing traditional energy-demand caused by population growth, sustainable supply capacity of the existing energy resources, potential for development of new and renewable energy resources, technology. This paper is divided into two parts: general energy issues and the modelling approach, and the application of this approach to Nepal in the context of fuelwood-supply sustainability.

    Abstract Communication between vehicles and road infrastructure can enable more efficient use of the road network and hence reduce congestion in urban areas. This improvement can be enhanced by distributed control due to its lighter computational load and higher reliability. Despite favourable impacts on traffic, little is known about the effects of such systems on near-road air quality. In this study, an End-To-End (E2E) dynamic distributed routing algorithm in Connected and Automated Vehicles (CAVs) was applied in downtown Toronto, to identify whether benefits to network throughput were associated with lower near-road NO2 concentrations. We observe significant reductions in the emissions of Greenhouse Gases (GHGs) with increased penetration of CAVs. Nonetheless, at times, the emissions of nitrogen oxides (NOx) increased with higher CAVs. Besides, a higher frequency and severity of NO2 hot-spots were observed under a 100% CAV scenario. Impacts of the proposed system on electric energy consumption in a full electric vehicle network were also investigated, indicating that the addition of CAVs that are electric did not contribute to high energy savings. We propose that such new transformative technologies in transportation should be designed with air pollution and public health goals.

    Abstract Conversion of carbon contained in the solid residues (tars + biochar) derived from urban biomass gasification named herein TC would allow enhancing the yield of carbon species (CO/CO2) in synthetic gas. For this purpose, three low cost materials have been tested as possible catalysts: iron species (reduced Fe), bone meal (BM), and ashes (ash) recovered from biochar complete oxidation. The parametric study used the following as variables: air GHSV, onset of reaction temperature, reaction time to optimize CO/CO2 molar ratio and tar content in the produced gas. Results showed an autocatalytic effect of biochar leading to the catalytic conversion of approximately 78% of tars by the native metals contained in TC. The catalytic effect was further enhanced by adding Fe, BM, and extra ash. Addition of Fe catalyst resulted in significant heat generation (temperature increase of ca. 500 °C) and a twofold decrease in reaction time to consume all the carbon. Use of ash and BM as catalysts exhibit heat generation comparable to Fe, along with an improved reaction time, complete tars conversion and a CO/CO2 molar ratio to above 1.3 in the produced gas.

    The assessment of greenhouse gases (GHGs) and air pollutants emitted to and removed from the atmosphere ranks high on international political and scientific agendas. Growing international concern and cooperation regarding the climate change problem have increased the need to consider the uncertainty in inventories of GHG emissions. The approaches to address uncertainty discussed in this special issue reflect attempts to improve national inventories, not only for their own sake but also from a wider, system analytic perspective. They seek to strengthen the usefulness of national emission inventories under a compliance and/or global monitoring and reporting framework. The papers in this special issue demonstrate the benefits of including inventory uncertainty in policy analyses. The issues raised by the authors and featured in their papers, along with the role that uncertainty analysis plays in many of their arguments, highlight the challenges and the importance of dealing with uncertainty. While the Intergovernmental Panel on Climate Change (IPCC) clearly stresses the value of conducting uncertainty analyses and offers guidance on executing them, the arguments made here in favor of performing these studies go well beyond any suggestions made by the IPCC to date. Improving and conducting uncertainty analyses are needed to develop a clear understanding and informed policy. Uncertainty matters and is key to many issues related to inventorying and reducing emissions. Considering uncertainty helps to avoid situations that can create a false sense of certainty or lead to invalid views of subsystems. Dealing proactively with uncertainty allows for the generation of useful knowledge that the international community should have to hand while strengthening the 2015 Paris Agreement, which had been agreed at the 21st Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC). However, considering uncertainty does not come free. Proper treatment of uncertainty is demanding because it forces us to take the step from “simple to complex” and to grasp a holistic system view. Only, thereafter, can we consider potential simplifications. That is, comprehensive treatment of uncertainty does not necessarily offer quick or easy solutions for policymakers. This special issue brings together 13 papers that resulted from the 2015 (4th) International Workshop on Uncertainty in Atmospheric Emissions, in Cracow, Poland. While they deal with many different aspects of the uncertainty in emission estimates, they are guided by the same principal question: “What GHGs shall be verified at what spatio-temporal scale to support conducive legislation at local and national scales, while ensuring effective governance at the global scale?” This question is at the heart of mitigation and adaptation. It requires an understanding of the entire system of GHG sources and sinks, their spatial characteristics and the temporal scales at which they react and interact, the uncertainty (accuracy and/or precision) with which fluxes can be measured, and last but not least, the consequences that follow from all of the aforementioned aspects, for policy actors to frame compliance and/or global monitoring and reporting agreements. This bigger system context serves as a reference for the papers in the special issue, irrespective of their spatio-temporal focus, and is used as a guide for the reader.

    Abstract Reasonable assessment of the environmental benefits of integrating forest products into global value chains (GVCs) is important to promote sustainable development. Based on the forest product sector data for 41 countries from 2002 to 2014, this paper explores the impact of GVC participation on carbon embodied in exports using the 2008 financial crisis, a quasi-natural experiment of negative global value chain shocks. We found that deepening backward participation in forest product value chains led to more substantial increases in carbon emissions than did forward participation. Countries with large decreases in GVC participation reduced more carbon embodied in forest product exports after the financial crisis (relative to countries with small decreases) through a larger reduction in the scale of forest product exports, and a decrease in the growth rate of capital-intensive products as a result of the relative decline in capital investment. They increased the embodied carbon of exports through a decrease in the growth rate of skilled personnel. Strengthening the technology effect of GVCs with the guidance of skilled forestry personnel is a key way to decrease exported embodied carbon.

    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.

    The Chinese government has grown increasingly invested in ecology in recent years. This paper discusses eco-efficiency using data envelopment analysis on 48 cities in Bohai Rim with special focus on the role of industrial structure upgrades. Based on the values from a super undesirable slack-based model, this study investigates eco-efficiency from temporal and spatial perspectives to reveal gaps among Bohai cities but an overall improvement in regional eco-efficiency. Moreover, this study adopts the Global and Local Moran's I to identify positive spatial autocorrelations and shows that most cites in Bohai Rim have high-high, low-low aggregation characteristics. Plus, the economic effects of per capita GDP, industrial structure upgrades on eco-efficiency are determined according to a spatial Durbin model. There appear to be negative spillover effects of industrial structure upgrades on surrounding cities, which reflects an industry transfer phenomenon related to eco-efficiency.

    Authors: Svitlana Bila;

    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.

    Abstract The accumulation of waste biomass and plastic and the inefficient combustion of low-quality coal is a major cause of energy loss and air pollution in rural China. This paper reports for the first time an experimental and multi-perspective analysis on an industrial scale co-pyrolysis of waste biomass and plastic. The results show that the resulting biochar product had a low calorific value of ≥21.0 MJ/kg, which meets the national standard for commercial solid fuel (GB/T 31862–2015). The calorific value of the produced gas was over 10 MJ/m3 and met the requirements of the national standard for residential heating and cooking (GB/T 13612–2006). The products of the co-pyrolysis can replace 1100 t of standard coal per annum, and reduce carbon dioxide emissions, sulfur dioxide emissions, smoke, and other contaminants at the rate of 1720 t, 5–6 t, and 320 kg, respectively, as well as reducing smoke pollution. In addition, through the recycling of 750 t of plastic waste per annum for use in the co-pyrolysis, this method can reduce the white pollution of 50–66.7 km2 of farmland in the local area. The present study can guide the optimization of such systems and lead to adequate flexibility in the co-pyrolysis of different wastes to generate economic and socioenvironmental benefits.
