Environmental Efficiency of Agriculture in Visegrád Group Countries vs. the EU and the World

The production of foodstuffs for an ever-increasing population is the basic, irreducible and unalienable function of agriculture. It involves environmental impacts, including greenhouse gas emissions. This is what makes it so important to examine the levels of environmental efficiency of agriculture. As countries differ in their emission levels, it is reasonable to look for what determines them. Hence, the purpose of this study was to identify the changes in the environmental efficiency of agriculture in Visegrád Group countries and worldwide in 1961–2020. These countries share a similar economic history and demonstrate comparable environmental and geographic conditions, making it possible to pinpoint the factors responsible for how the parameters covered by the study change over time. The research used data from the FAOSTAT database. Environmental efficiency of agriculture was defined as the relationship between production volumes in kilocalories and emissions. Initially, this parameter deteriorated in the Visegrád countries, but since the late 1970s it has improved, first linked to the crisis of the socialist economy and its collapse (including a drastic decline in livestock production) and then to the implementation of CAP instruments.

Global Energy Transition and the Efficiency of the Largest Oil and Gas Companies

The challenges posed by climate change and global warming loom large, necessitating a critical initial step towards the long-term growth and the enhancement of both environmental and operational efficiency. Within the energy sector, renewable energy sources are gaining increasing prominence. Consequently, traditional oil and gas companies (OGC) are undergoing a gradual transformation into comprehensive energy corporations, aligning themselves with energy transition policies. This paper examines two types of efficiency measures—operational and environmental—for the 20 largest OGC during the period of 2010–2019. Secondly, this research aims to explore the effect of the global energy transition on both environmental and operational efficiency. Based on three estimation methods, two estimation steps are used in this research. In the first step, the True Fixed Effect (TFE) model and the Battese and coelli (1995) SFA model are applied to evaluate, measure and compare the environmental and operational efficiency scores. In the second step, the TFE model and GMM approach for the dynamic panel data model are used to explore, evaluate and verify the effect of global energy transition on the environmental and operational efficiency of the largest 20 OGC in the world. The results reveal that the average operational efficiency of major OGC measured using the BC.95 model and TFE model is 66% and 85%, respectively, and the overall average level of environmental efficiency for OGC over a 10-year period is 31% (based to B.C.95 model) and 13% (based to TFE model). Our findings reveal that biofuels, solar and hydropower contribute to promote the operational and environmental efficiency of the largest 20 OGC. However, the analysis suggests that while the global energy transition significantly influences and bolsters environmental efficiency, its effect on operational efficiency among these major OGC remains less pronounced and insufficient.

Factors of Energy Transition of Manufacturing Companies Regarding their Inclusion in Global Value Chains

Environmental problems, the results of structural changes in the world economy and technological progress set forth the task of finding factors that stimulate the transition from the continuous growth of energy consumption to decarbonization and energy transition. The aim of the article is to empirically analyze the factors of companies' energy transition policies in different countries of the world, considering the functioning of global value chains (GVCs). The database is sourced from a survey of representatives of more than 15,000 manufacturing companies conducted by the World Bank Group in 2018-20 in 40 countries. The novelty of the analytical research framework proposed in the paper lies in the integrated presentation of factors which are external and internal to firms that influence decisions on energy transition policies and strategies. Descriptive statistics and econometric modeling revealed the presence of energy efficiency and energy transition policy elements in more than 2/3 of the sampled companies with a focus on energy efficiency, reflecting a desire to reduce related costs. Firms' use of fossil fuels is a driver of energy transition. Two alternative energy transition strategies of firms are found: the first emphasizes energy efficiency plans and actions, while the second involves a shift to carbon neutrality. High country income levels deter firms from energy efficiency decisions but incentivize the implementation of carbon emission reduction strategies. The level of environmental efficiency of countries has a positive impact on the "immersion" of their companies in the energy transition agenda. Companies' participation in the GVCs is generally positively associated with the presence of energy efficiency and energy transition policy elements. Government tax regulation and consumer demand are important factors in companies' commitment to energy efficiency and energy transition policies. Signs of the diffusion of incentives to implement energy transition policies along production chains are also identified. The results can be used in the development of industrial policy.

ENVIRONMENTAL DETERMINANTS OF SUSTAINABLE DEVELOPMENT OF THE COUNTRY

One of the key issues of environmental geography and a cornerstone in the implementation of any country’s sustainable development strategy is to ensure proper environmental protection. The purpose of the study is to determine the environmental determinants of sustainable development of countries with taking into account the need to harmonize the economy, ecosystem and human well-being. The novelty of the study is the further development of scientific approaches to assessing the interrelation between EPI and the structural elements of the “green” economy. The results of EPI statistical analysis showed that less than 1/3 of 34 European countries improved the effectiveness of their environmental policy in 2020 compared to 2018. Strategic positioning on the matrix models allowed to identify unequal numbers of strategic groups of countries with differences in the values of environmental determinants of sustainable development. It is substantiated that environment affect people’s life expectancy. Currently, the lowest value of healthy life expectancy is in Ukraine compared to other European countries. It is established that the unevenness in the dynamism of business in Europe is insignificant. However, the efficiency of the use of natural resources in the process of production and consumption, unfortunately, is not the same. The average share of renewable energy consumption in the sample of European countries is 23.5%. It is shown that a high share of renewable energy consumption does not guarantee a high level of environmental efficiency. However, this can be seen as an option to address the country’s energy security. It is proposed to combine the ecological determinants of sustainable development of the country into 4 groups: environmental protection; structural restructuring of the economy; resource efficiency and biodiversity; well-being and health of the population. It is concluded that positive changes in only one environmental determinant does not guarantee an increase in the level of environmental efficiency of the country (especially in the short term).

Environmental assessment of hydrogen: does hydrogen matter for environmental efficiency improvement?

ABSTRACT This paper first measures the level of environmental efficiency (EE) in 72 countries between 2001 and 2019 by adopting the Global Malmquist-Luenberger productivity index in the framework of the super slack-based-measure model. Then, by using the instrument variable-generalized method of moments (IV-GMM) approach, we examine the role of hydrogen development in increasing EE. We also pay attention to the asymmetric effect, the moderating effect, and the mediating effect in the hydrogen development-EE nexus. Several findings are highlighted as follows: (1) Hydrogen development can significantly increase EE. (2) The marginal impact of hydrogen development on EE is significantly positive in countries with a high level of EE, while it is insignificant in countries with a low level of EE, which shows the asymmetric EE enhancement effect of hydrogen development. (3) Foreign direct investment is a key moderating variable in the nexus between hydrogen development and EE, which can strengthen this positive nexus. And (4) mediating effect analysis documents that technological progress is an effective mediating variable through which hydrogen development affects EE. According to these results, we propose several policy implications for the acceleration of hydrogen development and EE.

Evaluation of Environmental Efficiency of Chinese Coastal Ports under the Background of Ecological Civilization

In order to enhance the level of green and sustainable development of the economy, the national policy of ecological civilization construction is proposed. The 14 coastal ports with the top 20 container throughput in China in 2020 are taken as the research objects, and the environmental efficiency evaluation index system of ports is constructed by combining the requirements put forward by ecological civilization, and the three-stage SBM model is applied to measure the environmental efficiency of 14 coastal ports in China from 2012 to 2020. It was found that the overall green development of Chinese coastal ports was good, with half of the ports achieving effective environmental efficiency with a mean value of 0.804 and a large gap in environmental efficiency levels among ports. External environmental variables have significant effects on the environmental efficiency of ports, and the overall environmental efficiency of ports with ineffective environmental efficiency has improved after excluding the effects of external environmental variables and random errors. Therefore, for ports with ineffective environmental efficiency, policy-related contents should be implemented effectively according to the actual situation of the port, and the environmental efficiency of the port should be improved from the perspective of the change and development of the port hinterland city, combining three aspects of local economic conditions, policy environment and cultural awareness.

Environmental Efficiency Evaluation of Construction Waste Generation Based on Data Envelopment Analysis and Malmquist Index

The rapid development of urbanization in China in recent years has resulted in the production of large amounts of construction waste, which has placed certain constraints on the sustainable development of the construction industry. This study measures the environmental efficiency of construction waste generated in China from static and dynamic perspectives using the data envelopment analysis and the Malmquist index with data from 30 Chinese provinces during the period from 2011 to 2020. The results showed that, from a static perspective, the environmental efficiency of China’s construction waste generation has been on a generally declining trend year by year, and the overall level is still not too high. At the regional level, there is a stepwise decline in the eastern, central, northeastern, and western regions. From a dynamic point of view, the overall Malmquist index in China has an average value of 1.016, indicating that the level of environmental efficiency of construction waste generation in China is in a state of improvement. From a regional perspective, the Malmquist index is highest in the east, indicating that the level of environmental efficiency of construction waste generation in the eastern region is developing well.

Can the Agglomeration of New Energy Industries Improve Environmental Efficiency?—Evidence from China

Improving environmental efficiency is the key to solving the contradiction between economic development and environmental degradation. In the process of realizing the “dual carbon” goal, the development of the new energy industry is typically characterized by having low carbon and is an important way to improve environmental efficiency. In this study, based on panel data from 2009 to 2018, the agglomeration levels of the new energy industry and the levels of environmental efficiency were measured. Moreover, the linear and nonlinear relationships between the agglomeration of the new energy industry and environmental efficiency were investigated, and the mediation effect model was used to verify the mechanism of action from a two-dimensional perspective. The results showed that (1) the levels of the agglomeration of the new energy industry (NEA) and environmental efficiency (EE) have generally increased with obvious “regional heterogeneity” and “polar characteristics”; (2) NEA can promote EE, with a marginal effect of 0.0347, but a strong positive driving effect only exists in the eastern region at present, which is higher than the national average level; (3) there is a double threshold effect within the process and the driving trend is “weak negative → weak positive → strong positive"; and (4) the advancement of industrial structures and direct foreign investments are the critical intermedia. Accordingly, this paper puts forward corresponding policy recommendations.

Efficiency Analysis and Estimation of Factors Affecting the Efficiency with Decision Trees in Imbalanced Data: A Case of Turkey’s Environmental Sustainability

Cities have proliferated and experienced increasing environmental issues in the modern world. The concept of environmental sustainability is one of the main problems to solve. Therefore, it is fundamental to establish statistical methods to measure environmental sustainability. The first aim of this study is to measure the environmental sustainability performance of 42 cities in Turkey by Data Envelopment Analysis. The second aim is to solve the imbalance in the efficiency values obtained using Synthetic Minority Oversampling Technique methods. After all, we expose the multiple relationships between input and output variables and efficiency using the Decision trees classifiers approach. As a result of the analyses, three internal factors were found to influence the environmental efficiency levels: residential sales, population intensity, and the number of completed industrial sites. It has been determined that the number of completed industrial sites and the increase in residential sales distorted environmental efficiency.

Environmental Efficiency Evaluation of China's Power Industry Based on the Two-Stage Network Slack-Based Measure Model.

How to achieve the continuous improvement of the environmental performance level of the power industry within the requirements of clean and low-carbon energy development is the fundamental requirement and inevitable choice for the construction of ecological civilization and sustainable development. From the perspective of environmental protection, based on the Data Envelopment Analysis (DEA) method and the internal mechanism of power system production and supply, the power industry environmental efficiency evaluation index system was constructed, and the two-stage Network Slack-based Measure (NSBM) model considering undesired output was used to calculate China’s 30 provinces and municipalities from 1998 to 2019. The environmental efficiency is divided into two links: power generation efficiency and transmission and distribution efficiency. The study found that, within the research interval, the overall environmental efficiency of China’s 30 provinces is low, and the differences between provinces and cities are large, but they have gradually developed in a better direction after 2015. The power generation efficiency of the first link in most provinces and municipalities is higher than the transmission and distribution efficiency of the second link, and the low transmission and distribution efficiency is an important reason for the low comprehensive level of environmental efficiency. The overall evolution trend of environmental efficiency in the six regions of China is roughly the same, but the regional differences are obvious, showing a trend of “high in the southeast and low in the northwest”. The economic and natural resource differences in different provinces and cities in each region have led to varying degrees of redundancy in five aspects, including investment in power assets, installed power generation capacity, and length of transmission lines, which seriously affect the environmental efficiency of the power industry. This research attempts to open the “black box” of the environmental efficiency conversion process of the power industry, which can provide directions and strategic suggestions for the improvement of the efficiency of the power industry in China.

R&D Spending in the Energy Sector and Achieving the Goal of Climate Neutrality

Research and development (R&D) spending in the energy sector, which is aimed at exploring ways to reduce greenhouse gas emissions, among other things, plays a vital role in achieving the goal of climate neutrality. The purpose of this paper is to assess the environmental performance of R&D spending in the energy sector of selected EU member states from 2011–2017/2019, and to compare the results. Taxonomic research with the zero unitarization method was used, which enabled a synthetic assessment of EU countries according to the environmental performance of the total spending in the energy sector and an analysis of the changes in performance for six categories of spending in this area. The assessment of changes in the environmental performance of individual categories of R&D spending over time using the applied method was an added value compared with the assessment methods previously used in this area. The study found that there were significant differences in the level of environmental efficiency of R&D expenditures in the energy sector between countries, changes in environmental efficiency in most of the countries studied were not satisfactory, the most environmentally efficient expenditures were on renewable energy, other power and storage, hydro and fuel cell technologies, and the least on fossil fuels and nuclear energy. The results reflected both the member states’ progress towards climate neutrality and the discussion on the environmental performance of the means and directions of actions aimed at this.

Effects of pollution abatement activities on environmental efficiency and productivity: Empirical evidence from the Chinese industrial sector

AbstractSince the 2000s, China has been aggressively involved in controlling industrial pollution, and end‐of‐pipe approaches have certainly reduced pollution emissions. This study aims to measure environmental efficiency and productivity in the Chinese industrial sector and investigate whether pollution abatement activities have a negative impact on environmental efficiency and productivity. Using regional data from 29 provinces from 1997 to 2010, the results show that significant improvements were made in environmental efficiency and productivity in the Eastern region, but not in the Western region. The estimation results after conducting a panel data analysis, however, show that increased pollution abatement activities are associated with a decline in environmental efficiency and productivity. The findings suggest that if China can promote the diffusion of cleaner production technology with the expansion of abatement activities, there is potential for increasing the levels of environmental efficiency and productivity.

The impact of economic growth, FDI, and innovation on environmental efficiency of the logistics industry in provinces along the belt and road in China: An empirical study based on the panel Tobit model.

Due to the high-quality development of the Chinese economy, the improvement of environmental efficiency in Chinese industries has become a significant task. Understanding the environmental efficiency of the logistics industry is essential for implementing effective environmental policies. This study aims to explore the impacts of economic growth, foreign direct investment (FDI), and innovation on the environmental efficiency of the logistics industry. In this paper, we apply the undesirable SBM model to calculate the environmental efficiency of the logistics industry and use the Tobit model to analyze the impacts of economic growth, foreign direct investment (FDI), and innovation on the environmental efficiency of the logistics industry in provinces along the Belt and Road in China from 2009 to 2018. Based on the results indicate the average environmental efficiency of the logistics industry in Chinese provinces along the Belt and Road is 0.7880, indicating that the environmental efficiency of the logistics industry was generally low in some regions along the belt and road. Innovation and FDI were found have a significant impact on the environmental efficiency, while economic growth fails to significantly impact on the environmental efficiency of the logistics industry in provinces along the Belt and Road. Therefore, we should encourage improvement of the level of environmental efficiency of the logistics industry. It is necessary to realize the co-ordinated development of the logistics industry and the environment through optimization of the development of innovation and transforming the FDI model in provinces along the Belt and Road.

Nanotechnology use to preserve the durability of archaeological brick buildings in Al-Najaf city

Archaeological buildings constitute the urban core of historical cities, supporting both private identity and urban life in society. Old Najaf city may be the most important city in Iraq due to its religious and spiritual value in the Islamic world; its archaeologic buildings thus represent the features of both collective memory and the private reality of cultural heritage. This research aims to achieve examine the use of nanomaterials in terms of contributing to the preservation of archaeological buildings built with bricks in Najaf City in particular, and Iraq in general, helping determine how to use these to prolong the life of these buildings based on the assumption that certain nanomaterials can prevent harmful environmental factors from affecting such buildings or causing further damage. This would allow a high level of environmental efficiency and help to perpetuate these historic buildings, as such treatments do not cause any changes in the original physical or chemical properties of heritage buildings. The study results suggest that Nano-treated bricks can effectively be used as a new building material for additive parts used to support archaeological buildings, thus offering access to buildings with high environmental efficiency.

STUDY AND CATALOGUING OF INDIGENOUS VERNACULAR ARCHITECTURE IN WESTERN PANAMA

Abstract. The results of a research project on the vernacular architecture of indigenous communities in western Panama are presented. The field of study focuses on the indigenous territories of the Ngäbe, Buglé, Naso and Bribri ethnic groups, close to the border with Costa Rica. All of them belong to a well-defined geographical area and are linked by close historical, social and cultural ties. The constructions studied are based on the use of plant materials from their immediate surroundings, have enormous geographical, historical and ethnological value, and reflect the distinct lifestyles of the people who built and used them. Fully adapted to their natural environment and embracing high levels of environmental efficiency and sustainability, these constructions are nevertheless little known, little valued outside their region (and even within it), and are in serious danger of disappearing due to the introduction of new building materials. This paper presents the results of the current research project which emphasizes the morphology, structure, materials, construction techniques, typology and function of the buildings under study; and presents the working processes related to their construction.

Total Factor Environmental Productivity in the Mediterranean Countries: A Malmquist–Luenberger Index Approach

This paper examines the environmental productivity in the Mediterranean countries over the period 2009-2014.We use the Malmquist-Luenberger productivity index (MLPI) that can handle undesirable outputs within Data Envelopment Analysis (DEA) approach. We decompose the MLPI index into technical efficiency, technological change and scale efficiency change in order to determine the source of productivity changes. Empirical findings indicate that the total factor environmental productivity in the Mediterranean countries have a negative developmental trend. Furthermore, we find that technological progress is the main source of productivity growth. Finally, Mediterranean countries need a considerable effort on R&D to optimize the potential for technical development and enhance the environmental efficiency levels.

ЕКОЛОГІЧНА ЕФЕКТИВНІСТЬ УПРАВЛІННЯ ЗЕМЕЛЬНИМИ РЕСУРСАМИ ЯК ОСНОВА СТАЛОГО РОЗВИТКУ СІЛЬСЬКИХ ТЕРИТОРІЙ

Introduction. The competitiveness of land use within a market economy is determined by the equation of capital expenditures, labor power that integrates land into a single engineering procedure, as well as natural and anthropogenic means with the help of which land resources are leveraged, and soil fertility is restored by rational organization of the system of adaptive-landscape specific agriculture. Therefore, the relevance of research of environmental efficiency of land resources management as the basis of sustainable rural development is beyond any reasonable doubt.Purpose. The purpose of the article is to investigate the environmental efficiency of land resources management and its impact on sustainable rural development.Results. Based on the research findings of the totality of indicators of environmental efficiency of land resources management, we will distinguish those ones that make important analysis findings at the national level for such land resources agents as micro agents; mini-agents; general agents; the state; local agents; global agents. Among all the test items of environmental efficiency of land resources management, the agent of land interests “the state” responds to 26 indicators. In addition to the existing indicators, a number of multiplicative metrics has been added for analysis. By expertise, among the presented indicators we have selected 15 under three criteria – anthropogenic impact, reproduction, harmonization. At the same time, in the author's opinion, the environmental efficiency of land resources management of the rural economic sector is to ensure the efficient land use as a constituent of the environment. With provision for expert estimation, we have offered a set of evaluative criteria for the level of environmental efficiency of land resources management of the rural economic sector.Originality. There has been proposed the map of forecast impacts of indicators of environmental efficiency of land resources management, which shows an extremely high level of influence of environmental component of sustainable development on the integral estimation of land resources management, in particular indicators of the amount of used agricultural chemicals per 1 ha of area under crops, land resources usage per a unit of gross production, proportion of sunflower and bird rape in cropping system. A computer program was used to predict the change in the value of integrated efficiency of land resources management using the proposed methodological approach. This computer program, taking into account interinfluences, makes it possible to calculate the predictive influence ranking of indicators on the assessment of the integrated efficiency of land resources management.Conclusion. The article deals with the possibilities of land resources management within the framework of sustainable development of rural territories. The criteria for environmental efficiency of land resources management include: anthropogenic impact – the main indicator – the usage of agricultural chemicals per 1 ha of area under crops; reproduction – environmental and agrochemical assessment of soils; harmonization – the relative gravity of eroded lands acreage in the structure of agricultural fields. Multiplicative indicators, the essence of which is to assess the intensity and efficiency of the parties to land relations, are taken into account for each type of efficiency of land resources management. We have implemented the matrix of forecasts of integral efficiency of land resources management in the rural economic sector in reliance on the method of criterion diagnostics, which is based on the use of a program that takes into account maps of forecast impacts of indicators of environmental efficiency of conditional, relative and absolute input indicators. The practical importance of the obtained research results is that we not only have calculated the predictive rating of the impact of the criterion indicators on the assessment of the integrated efficiency of land resources management, but also the results of the change to 1 conditional score of the input indicator. This technique permitted to reveal the most significant influence on the effectiveness of specific environmental indicators – livestock density and specific gravity of the area under crops, fertilized with organic fertilizers, which indicates the impossibility of effective land use without livestock-raising development.

Efficiency Environmental Policy: Input-Output Approach Orientation

This study has the objective to calculate and analyze environmental efficiency when a country ratified the Kyoto Protocol or not to ratify it both the developed and developing countries as well. Output to be analyzed is GDP and CO2 emissions, while the input to be analyzed is the use of energy, stocks traded and Labour. The analysis Metod of is Envelope Data analysis (DEA) with samples of G20 countries by 2004-2014. To be analyzed is the degree of efficiency after implementing the Kyoto protocol and how the processing results when viewed from based on the input and output targets. This is to answer the formulation of the problem posed in this study namely How the level of environmental efficiency if the Kyoto Protocol is implemented and how policy advice for each of the G20 countries based on the input and output targets. The study concluded the following: with the policy implemented Kyoto Protocol was able to further improve environmental efficiency in some other countries such as Russia, Argentina, China and Germany. This shows that the policy of the Kyoto Protocol been successful in carrying out its role as controller of the growth in emissions in developed countries and growing, especially G20 members. Besides, there are also countries that suffered losses in the level of environmental efficiency if not implement the Kyoto Protocol. But on the other side of some countries are not affected if there is no Kyoto Protocol, for example Italy, Mexico, Saudi Arabia, Australia and America. Efficiency is not the only primary standard to make a country become a standard for other countries, on the other hand the performance quality of the environment should also be considered. One country may succeed in reducing the environmental inefficiency by ratifying the Kyoto Protocol, and it has the efficient performance in relation to environmental quality and sustainable productive based on Malmquist index. Based on the criteria of the target input and target output, it can be seen that the member countries of G20 reach the optimal level when viewed from the variable GDP (positive output) and shares traded or stock traded (input) eg Argentina, Australia, Brazil, Canada and Indonesia. However, this is not optimal when viewed through the use of energy (input target), emissions (output targets), and labor (input target).
