COVID-19 has a severe and widespread impact, especially in Indonesia. COVID-19 was first reported in Indonesia on March 03, 2020 then rapidly spread to all 34 provinces by April 09, 2020. Since then, COVID-19 is declared a state of national disaster and health emergency. This research analyzes the difference of CO, HCHO, NO2, and SO2 density in Jakarta, West Java, Central Java, and South Sulawesi before and during the pandemic. Also, this study assesses the effect of large scale restrictions on the economic growth during COVID-19 pandemic in Indonesia. In a nutshell, the results on Wilcoxon and Fisher test by significance level α=5% as well as odds ratio showed that there are significant differences of CO density in all regions with highest odds ratio in East Java (OR=9.07), significant differences of HCHO density in DKI Jakarta, East Java, and South Sulawesi. There are significant differences of NO2 density before and during public activities limitation in DKI Jakarta, West Java, East Java, and South Sulawesi. However, the results show that there are no significant differences of SO2 density in all regions. In addition, this research shows that there are significant differences of retail, grocery and pharmacy, and residental mobility before and during the COVID-19 pandemic in Indonesia. This research also shows that during the COVID-19 pandemic there are severe economic losses, industry, companies, and real disruptions are severe for all levels of life due to large scale restrictions.

Air pollution has become a serious concern for its potential health hazard, however, often got less attention in developing countries, like Bangladesh. It is expected that worldwide lockdown due to COVID-19 widespread cause reduction in environmental pollution in particularly the air pollution: however, such changes have been different in different places. In Chittagong, a city scale lockdown came in force on 26 March 2020, a week after when first three cases of COVID-19 have been reported in Bangladesh. This study aims to statistically evaluate the effects of COVID-19 lockdown (26 March to 26 April 2020) on selected air quality pollutants and air quality index s. The daily average concentrations of air pollutants PM10, PM2.5, NO2, SO2 and CO of Chittagong city during COVID-19 lockdown were statistically evaluated and were compared with dry season data averaging over previous 8 years (2012 to 2019). During lockdown, except NO2, all other pollutants studied showed statistically significant decreasing trend. During the COVID-19 shutdown notable reduction of 40%, 32% and 13% compared to the daily mean concentrations of these previous dry season were seen for PM2.5, PM10 and NO2, respectively. The improvement in air quality index value was found as 26% in comparison to the previous dry season due to less human activities in COVID-19 shutdown. The factor analysis showed that AQI in Chittagong city is largely influenced by PM10 and PM2.5 during COVID-19 shutdown. The lesson learnt in this forced measure of lockdown is not surprising and unexpected. It is rather thought provoking for the decision makers to tradeoff the tangible air quality benefits with ongoing development strategies’ that was often overlooked directly or indirectly.

At the end of 2019, the new virus called Coronavirus Disease (Covid-19) spread widely from China all over the world. In March 2020 the World Health Organization declared a new virus outbreak as “a global pandemic”, and recommended social distancing and quarantine. Most countries in Europe have been quarantined. The social aspect of this issue is complicated by the fact that Europe nowadays hosts 82 million international migrants. If migrant workers leave the host country, it reduces the Covid-19 spread. Nevertheless, if migrant workers do not return, it will worsen the situation with the economic crisis. The subject of the study is the instrumental and mathematical aspects of impact simulation of labor migrants’ policy on the economic growth of the host country affected by COVID-19 pandemic. The aim of the work is to develop the system dynamics model for assessing labor migrants’ policy impact on the economic growth of the host country during COVID-19 pandemic. It examined through hypotheses of different scenarios of labor migrants policy impact on the host country economic growth in Covid-19 pandemic. The proposed model combines epidemiological and the economic growth models and relies upon real statistical data. The analysis was carried out in four European countries. The results of the study enabled to state that without migrant workers the gross domestic product may fall to 43% in Italy, 45% in Netherlands, 37% in Spain and 200% in Switzerland in 2020.

The coronavirus disease 2019 (COVID-19) has been identified as the main cause of the outbreak of the respiratory disease in Wuhan, Hubei Province of China in December 2019. Since then, the epidemic has spread rapidly throughout China and many other countries in the world. This study, therefore, examines the spatiotemporal distribution of the confirmed cases of COVID-19 and its effect on human development in China, and suggested social and non-pharmaceutical preventive interventions to help curb the further spread of the disease. The public open data available from January to February 2020, from the National Health Commission of the People’s Republic of China and a medical knowledge sharing website were used, and spatial analysis was performed to visualize the spatial distribution pattern of COVID-19 in China. The results showed among others that COVID-19 had entered a dispersed spatial pattern, resulting in increased pressure to control the spread of the disease. In early March, there was a significant reduction in the existing number of cases, and the number of deaths also decreased. At the provincial level, the spatial distribution of the number of cumulative confirmed cases in China was divided into four patterns: Hubei was the initial core region; the eastern provinces adjacent to Hubei formed the second concentrated pattern; the western provinces adjacent to Hubei and the northeastern and southeastern provinces which were separated from Hubei by one province belonged to the third distribution pattern; while the rest of the provinces in the north, south and west showing sporadic distribution patterns formed the fourth. It has been estimated that about 80% of students’ online learning at all schools were not effective due to lack of access to reliable and uninterrupted internet services especially in the rural areas of China.

The outbreak of coronavirus disease (COVID-19) was first reported from Wuhan, China, on December 31st, 2019. As the number of coronavirus infections has exceeded 100,000 with toll deaths of about 5000 worldwide as of early March, 2020, scientists and researchers are racing to investigate the nature of this virus and evaluate the short and long term effects of this disease. Despite its negative impacts that obliged the World Health Organization to declare COVID-19 epidemic as a Public Health Emergency of International Concern, the rate of mortality of this infection has not exceeded 3.4% globally. On the other hand, the mortality rate caused by ambient air pollution has contributed to 7.6% of all deaths in 2016 worldwide. The outbreak of COVID-19 has forced China to lockdown its industrial activities and hence dropped its NO2 and carbon emissions by 30 and 25%, respectively. This work reports on the first case study that compares the air quality status before and after the crisis. It sheds light on the facts related to the demographics of deaths by gender, age and health status before infection. The historical data on air quality, estimates of annual deaths and its economic burden have been presented and analyzed. The actual daily deaths due to COVID-19 have been obtained from the official records of the daily Situation Reports published by World Health Organization as of March 11th. The rate of mortality due to COVID-19 was impacted by two factors: age and health status. Results show that 75% of deaths were related to cases that had underlying present diseases with the majority aged of 80+ years. The reported figures were compared with the average daily mortality due to poor air quality which reached up to 3287 deaths due to high levels of NO2, O3 and PM. The air quality status before the crisis was compared with the current situation showing that COVID-19 forced-industrial and anthropogenic activities lockdown may have saved more lives by preventing ambient air pollution than by preventing infection.

This study assessed the knowledge, attitudes and practices on food waste of selected households in the northern province of the Philippines. The results of the assessment were used as bases for formulation of a recycling system. A total of one hundred rural households were selected using stratified equal allocation sampling technique. Data were collected through the use of researcher-made questionnaire with Cronbach’s Alpha at .82, and was supplemented by observations. Factor analysis, Pearson r, and point-biserial correlation were used to yield findings in the study. Results show that a number of factors discourage the respondents’ participation in the reduction and recycling of food waste, such as lack of facilities, insufficient training, and information dissemination. Household size (r=.199, p<0.05), monthly income (r=.282, p<0.01; r=-.217, p<0.05), and planning (r=-.243, p<0.05) influences the way the participants manage household food waste. On the other hand, age, educational attainment, and sex, do not significantly affect the way the household-participants manage food waste. One strategic and feasible solution is a compulsory food waste recycling system (FWRS) for private households to combat this pressing issue on food waste. This proposed framework is composed of four major moves that require the collaboration of various sectors and stakeholders in the community, and is expected to suggest valuable policy amendments including significant decrease in wastage of consumable agricultural products. Without doubt, the ongoing over generation of food waste is a serious global setback that needs to be urgently addressed.

Carcinogenic and systemic health effects of arsenic exposure in drinking water are well documented. This study estimated the risk associated with chronic consumption of water with high concentrations of arsenic in children and adults living in six Andean locations, in Chile. Concentrations of arsenic in the drinking water were analyzed between 2014 and 2017 based on health authority reports and data collected during this study. Average daily arsenic intake was estimated, and systemic (HQ) and deterministic carcinogenic risk (CR) indices were calculated using U.S. Environmental Protection Agency methodology. Threshold values of HQ>1 and CR> 1 x 10–4 were considered to indicate high risk of adverse health effects. Four of the locations (Chucuyo > Putre > Humapalca = Visviri) had high concentrations of arsenic in the water, at levels 6.3–57.6 times the norm of 0.01 mg/L, Zapahuira and Belén, had values just below the threshold. Extremely high HQ values were estimated in children, at 1.3–119.8 times the threshold. Furthermore, CR values were several orders of magnitude (3.06–10790.6) above the tolerable value among all age strata. The locations studied have a high risk of adverse health effects from exposure to arsenic in drinking water. It is urgent to implement mitigation measures to improve water quality in these communities and to carry out probabilistic studies to provide more accurate assessment of exposure.

This study provides a multidimensional analysis of sustainable socio-economic development and its challenges in the rural areas of Ukraine. The methodology of realization of sustainable development’s conceptual provisions was created. The advantages of using indicative assessment at the regional level were justified. The methodical approach how to define the indicators of sustainable development (including economic, socio-demographic, labor and environmental domains) of rural areas was proposed. Statistical data, experts’ and rural residents’ evaluation were used to assess the level of socio-economic development of rural areas. The proposed system of indicators is applicable not only to the rural areas of the whole region, but also to its different parts. The tracking model is based on the consistent use of economic, mathematical and expert methods: SWOT-analysis, factor, cluster and discriminant analysis. The construction of the dendrogram allows to determine the type of representative for each cluster. The modeling of sustainable socio-economic development for each sample is applicable to all areas within same cluster. A representative sample from each cluster makes it possible to identify the presence in the region of the so-called "points of growth" and to forecast their development. Two scenarios are considered: maximum (the share of GRP accumulation growth 21.2%) and moderate (the share of GRP accumulation growth 10.6%). GDP Gross Domestic Product growth will differentiate by the type of activity: cluster 1 (agriculture, hunting and forestry) 13% increase; cluster 2 (trade, service and household services) 21% increase; cluster 3 (tourism and international cooperation) 18% increase; cluster 4 (processing industry) 8% increase. Therefore, the using of key indicators for monitoring the sustainable development of rural areas provides an opportunity to take into account the specifics of sustainable development of different specialization branches of rural areas that will support high economic and social growth in the future.

This study analyzes the characteristics of land use/land cover change in Jordan’s Irbid governorate, 1984–2018, and predicts future land use/land cover for 2030 and 2050 using a cellular automata-Markov model. The results inform planners and decision makers of past and current spatial dynamics of land use/land cover change and predicted urban expansion, for a better understanding and successful planning. Satellite images of Landsat 5-thematic mapper and Landsat 8 operational land imager for the years 1984, 1994, 2004, 2015 and 2018 were used to explore the characteristics of land use/land cover for this study. The results indicate that the built-up area expanded by 386.9% during the study period and predict further expansion by 19.5% and 64.6% from 2015 to 2030 and 2050 respectively. The areas around the central and eastern parts of the governorate are predicted to have significant expansion of the built-up area by these dates, which should be taken into consideration in future plans. Land use/land cover change and urban expansion in Irbid are primarily caused by the high rate of population growth rate as a direct result of receiving large numbers of immigrants from Syria and Palestine in addition to the natural increase of population and other socio-economic changes.

Due to the growth of population and industrialization, a great number of problems associated with producing industrial wastes have been created for both the environment and human beings. The industrial waste management in Brujen industrial park, located in the western part of Iran, has been investigated in this study using the environmental rapid impact assessment matrix technique. For this purpose, the effective activities and components were classified. The determination of the best scenarios with the least impact on the environment was performed by developing the scenarios for possible industrial waste disposal and making calculations by the rapid impact assessment matrix method. The components of the environment were first classified into physical/chemical, economic/operational, biological/ecological, and social/cultural items. Afterward, with respect to the criteria of the rapid impact assessment matrix method, the importance of environmental impacts was determined by standard scoring of the developed scenarios. Ultimately, the environmental score of each component for the scenarios was calculated using the rapid impact assessment matrix method, and the best scenario with the least environmental impacts was selected through a quantitative comparison. According to the results, scenario 3 (pyrolysis) and scenario 1 (recycling) were found to have the most negative impact and the most positive impact on the environment. Scenario 4 (incineration), with its severe air pollution, obtained a high negative score and was excluded from the options. As a result, two systems of recycling (scenario 1) and the sanitary landfill (scenario 2) were identified as complementary to each other and were selected as a solid waste management method.

The study attempts to assess the impact of the educational level of the country’s population, the level of science and technology development on the general environmental environment. The aim of this article is to assess the impact of educational level and level of science development on individual elements that reflect the state of the environment. To receive the obtained results is being used the package of statistical programs STATISTICA. The intense connection between educational level and aggregated evaluation of Environment Performance Index has been established. The significant correlation was found between the education index and the ecological conditions in countries with a very high, medium and low level of Human Development Index. The significant correlation between the processes of implementation of educational and science public policy and a set of environment’s criteria was found. The obtained models have been proved that for underdeveloped countries investment in education and science has a more significant impact on the ecological situation than in highly developed countries. Finally, this study concluded that public policy in the area of science and education, aimed at improving the ecological situation in the country, should be differentiated depending on the level of country development.

In this study, the relationships between two variables: the strategy of sustainable development and the efficiency of waste management in the commercial power industry company have been subjected to discussion. The basis for the explanation of the aforementioned relationships is the assumption that the level of implementation of the strategy of sustainable development is expressed through capital expenditures incurred on the implementation of modern tools of waste management. On the other hand, the efficiency of waste management in the commercial power industry company is reflected by the level of costs incurred on the storage, transport, and sales of this waste. The whole of the presented considerations has been divided into two basic parts, theoretical and empirical. The first part of the paper exposes the strategic dimension of the concept of sustainable development taking into account the economic and environmental efficiency of waste management achieved due to the use of modern management tools. The considerations presented in the second part constitute the response to the research question. The empirical part includes the identification of waste in the commercial power industry company in Poland and the research aiming at the cognition and assessment of relationships between the efficiency of waste management and the implementation of the strategy of sustainable development in the surveyed company. The publication increases the understanding of the coexistence of the strategy of sustainable development and the efficiency of waste management in the company of the commercial power industry operating in Poland, with particular emphasis on waste reduction and the possibility of its redevelopment. The research methods applied to accomplish the objective are literature studies, case study, descriptive analysis, trend analysis, and the Pearson correlation coefficient.

The study relates to the problem of cluster management in the conditions of sustainable development. Against the background of the assumptions and conditions for sustainable development, the specificity of the cluster activity in the conditions of the Polish economy has been presented. The objective of the paper is to characterize the cluster management standards in Poland. Such standards have been formalized and published lately with the recommendation for their application by the Polish Agency for Enterprise Development. They constitute the response to the low level of the existing cluster management and lack of the system approach to the issue of the preparation of professional coordinators, whose significance is crucial for the cluster success. In the paper, the methods of literary study and the analysis of secondary data have been applied. The paper begins with the characteristics of the principles of sustainable development and their impact on cluster activity. It also indicates the role and significance of clusters in the contemporary economy. Subsequently, the author has conducted an analysis of cluster activities in Poland. The last part of the paper refers to the Polish standards for cluster management as well as the conclusions and recommendations.

The issue of accidents at work and accident prevention have a significant impact regarding safety, health protection and work environment management for the European Union. Work conditions need to be improved in Poland. Solving this collective issue caused by humanitarian as well as economic considerations is a primary mission in businesses. Creating more quality jobs is one of the main goals of the EU’s social policy. Health and safety in the work environment are essential conditions for work quality. This article presents the incidence of work-related accidents in the EU. In the 28 member states of the EU (EU-28), 2015 recorded over 3.2 million workplace accidents which invoked at least 4-day work leaves and 3,876 deaths. The authors of this analysis present the issue of workplace accidents based on the examination of incidents in large foodstuff plants of the Lodz voivodship i.e. food processing businesses that have been continuously active for the five year period of 2008-2012. The food industry belongs to one of the most fundamental economic fields and is one of the most important factors of economic growth and amounts to about 20% of domestic production in the processing industry in Poland. The Lodz province has been chosen on account of its central location in the country. For the selected group of businesses, there is a marked increase of workplace accidents – from 258 in 2008, to 333 incidents in 2012 – for the study period in that the lowest incidence occurred in 2009 (211 accidents), and the highest in 2011 (358 accidents).

The sectoral structure of most agricultural enterprises is unbalanced and uncoordinated, which underlies the need in deepened research of its improvement. This paper is dedicated to the formation and evaluation of the sectoral structure with the use of mathematical methods of data processing. Mathematical economic modeling based on optimization and simulation models has been applied for the formation and evaluation of sectoral structure in agricultural enterprises. The approbation of the aforementioned models has been carried out in a certain agricultural enterprise. The simulation modeling has been used to develop a production model by the types of products that enterprise does not produce (milk, fish products and honey). The optimization model has been developed taking into account the rational use of the enterprise’s land with the prospect of livestock sector development. Obtaining the maximum net income (proceeds) from products sales has been chosen as the optimality criterion. According to calculations, the maintenance of cows is unprofitable; the production of fish and honey is profitable. Due to the diversification of the sectoral structure, the enterprise’s profitability level will increase from 16.6 to 45.8 percent. The implementation of optimization and simulation models allows to assess the existing level of sectoral structure in agricultural enterprise and to form its optimal sectoral structure with ensuring the rational use of resources and obtaining profit.

Eco-innovation is any innovation that leads to sustainable development by limiting the negative impact of production activities on the environment, increasing the resilience of nature to loads or ensuring greater efficiency and responsibility in the use of natural resources. Eco-innovations are the opportunity for enterprises. Their introduction contributes to reducing the costs of doing business, allows you to take advantage of new opportunities development and positively affects the company's image. The main goal of the research is to recognize the situation and the level of eco-innovation in Poland, including the micro, small and medium enterprises sector and to compare the obtained results with the ones from European Union countries. The result of the research is indicating the barriers and opportunities to support the development of eco-innovation in the micro, small and medium enterprises sector in Poland. Lack of financial resources for eco-innovation was indicated as the largest barrier by MSMEs in Poland. The most significant barriers to eco-innovation in Poland are mainly of an economic nature, including the high cost of implementation, difficult access to capital, uncertain return on investment and the weak system of economic and fiscal incentives encouraging eco-innovation.

The markets globalization is one of the factors creating conditions for the development of entrepreneurship. Entrepreneurship does not have one generally accepted definition. Most often, entrepreneurship is perceived as the ability to increase the number of enterprises. Entrepreneurship can be understood as the potential to identify and use development opportunities regardless of own resources. Entrepreneurship is therefore associated with such areas as new organizational forms, stimulation of innovation and cooperation with the entrepreneurial environment. Unfortunately, enterprises face many difficulties which can have the supply and demand nature. These difficulties hinder the enterprise functioning on the market and its development. Logistics performance perceived as the implementation of the highest quality of logistics standards allows overcoming the difficulties of entrepreneurship, especially for the transport and storage sector. For this reason, the article aims to determine the relationship between logistics performance and the entrepreneurship rate for selected European Union countries. Logistics performance was determined by a synthetic measure of development estimated using numerical taxonomy methods for variables forming the Logistics Performance Index. The same method was used to build the entrepreneurship rate, accepting as variables selected entrepreneurship indicators for the transport and storage sector. The correlation analysis was performed with the use of the Spearman rank correlation coefficient. The years 2014-2016 were analyzed. The availability and completeness of data dictated the choice of years, countries and indicators for analysis.

In this study criterion of maximum profit intensity for transportation problems, in contrast to the known criteria of minimum expenses or minimum time for transportation, is considered. This criterion synthesizes financial and time factors and has real economic sense. According to the purpose of this paper, the algorithm of the solution of such a transportation problem is constructed. It is shown that the choice is carried out among Pareto-optimal options. Moreover, the factor of time becomes defining for the high income from transportation, and the factor of expenses – at low ones. Not absolute but relative changes of numerator and denominator become important when the criterion represents the fraction (in this case – the profit intensity as the ratio of profit to time). A nonlinear generalization of such transportation problem is proposed and the scheme of its solution in a nonlinear case is outlined. Graphic illustrations of Pareto-optimal and optimal solutions of transportation problem by profit intensity criterion are also given.

Grain production is one of the Ukrainian agro-industrial complex main branches. An indicator of the grain production efficiency is its profitability. It is characterized by significant annual fluctuations that induce risk. Redistribution of existing grain crops areas taking into consideration their profitability can bring to increase of production efficiency. The paper observes Markowitz’s optimal portfolio theory appliance to grain branch. The central aim of this work is the development and justification of a new technique of sown areas portfolio risk evaluating. In this study, the annual profitability of four cereal crops cultivated in the Rivne region: wheat, barley, corn, and oats, have been analyzed. It is shown that the profitability of the cereals is not normally distributed. Under these conditions, the portfolio variance loses part of its informativity and can not serve as a good risk measure. It has been determined that the profitability of crops with good precision follows Laplace distribution (double exponential distribution). The analytical expression for Value-at-Risk measures has been obtained using the Laplace distribution function. Numerical risk assessments performed. Using a modified Markowitz model and obtained risk estimates the efficient frontiers of cereal sown areas portfolios in the Rivne region were constructed. Obtained results allow indicating ways for optimization the region grain industry structure.

Ukrainian agriculture creates 12-14% of GDP. Ensuring the conditions for sustainable economic development implies the use of adequate mechanisms for regulating economic processes by the government. In the process of formation and implementation of the organizational and economic mechanism of regulatory policy, a system of indicators plays an important role in assessing the impact of such policy on the participants, monitoring and, in case of the deviation from planned results, adjusting regulatory measures. This research analyzes and systematizes the indicators that determine the organizational and economic mechanism of regulatory policy effectiveness in agriculture. The systematization of indicators to evaluate the organizational and economic mechanism of regulatory policy effectiveness in agriculture has allowed substantiating the methodological principles of its integrated assessment. Application of the proposed methodological approach to assessing the organizational and economic mechanism of regulatory policy effectiveness in agriculture in Ukraine was performed during 2010, 2016-2017 period. It revealed slow progress in the organizational and economic mechanism of regulatory policy efficiency during the investigated period. This result is primarily attributed to the lack of purposeful, systematic change management, the lack of mid-term planning, the strictness of most programs, imperfect financial instruments of the organizational and economic mechanism, and procedures for application.

The level of information today is decisive in the socio-economic development of the country. The purpose of the article is to identify the most influential factors in the process of developing informatization in the context of international globalization. The assessment of factors influencing world information is based on the following stages: forming incoming information about the state of world information, a methodical approach to assessing the impact of world information, modeling the interrelation of components, the influence of world information as hidden factors in the development of information. Factor and correlation analyses are carried out within each cluster with a single level of information by groups of countries. Based on the calculation of factor loads, the most influential indicators have been determined, which serve as the basis for the formation of the informatization process mechanism in the countries of each cluster group. Accordingly, for example, from Innovations and Improvement Factors the major ones were only for the second cluster: Government efficiency and Efficiency of goods market and for the third cluster was the Global Competitiveness Index. The study allowed to determine the main priorities for the development of information in the context of clusters, formed in accordance with the level of information development in the country of each group. Interpretation of the results allowed determining the most influential factors in the development of informatization of the countries of each group, which is the basis for forming recommendations on organizational measures to increase the level of informatization in the context of international globalization.

The way of perceiving the environment is the factor informing on the condition of the environment and its impact on the operation of enterprises whereas the impact on the operation is the factor determining how enterprises operate in realities where there is no place for atomized actions of isolated enterprises and the impact of the environment and relationships with its constituents and all forms of inter-organizational and interpersonal relationships are of increasingly critical importance. The objective of the study is to analyze the perception of the environment in which modern small enterprises operate. The study question relating to this problem was formulated as follows: 1) what is the perception of the environment by the entrepreneurs representing small enterprises? 2) Is the environment of small enterprises perceived as unfriendly (dynamically changing, hostile, heterogeneous) by them? The research tool was the questionnaire. The statistical analyses were conducted using the R Package. While summing up the results of the conducted research, it should be concluded that, in most studies in the field of management of modern enterprises, a frequent observation is defining the environment as turbulent or ultrafast. The perception of the entrepreneurs under research indicates, however, a slightly different, more lenient approach to the environment. Although they were not directly asked about the level of turbulence of the environment, the obtained results, maintaining the characteristics of the environment in the middle of the scales (dynamism, hostility, heterogeneity) indicate that this environment is not perceived in a drastic and pessimistic manner.
