Analysis of Urbanization and Energy Consumption Using Time Series Data: Evidence from the SAARC Countries

Urbanization has posed some tremendous challenges which are related to environmental stresses through increased energy consumption. These challenges have drawn attention to the need to implement urbanization with sustainable energy consumption globally. The present study aims to identify the urbanizing factors that cause energy consumption in the SAARC countries. The South Asian Association for Regional Cooperation is considered in the study during the period of 1975-2014. The data are analyzed by using simple statistics and econometric techniques, such as the ordinary least squares (OLS) method for the country level. The study has found that all urbanizing variables significantly affect energy consumption with different levels in different countries, as shown by the OLS method. The coefficient of GDP is statistically significant at 1% level of significance for Bangladesh, Pakistan and Sri Lanka, while at 5% and 10% levels for India and Nepal, respectively. The coefficient of the industrial sector share in GDP is statistically significant at 1% level of significance for Bangladesh, Nepal and Pakistan. The result shows that a 1% increase in the service sector’s share in GDP leads to a reduction in energy consumption of 0.15%, 0.34% and 1.61%, respectively, in Bangladesh, Nepal and Sri Lanka. The result for urban population indicates that a 1% increase in urban population leads to an increase in energy consumption by 1.94%, 2.32%, 0.85% and 3.87%, respectively, for Bangladesh. India, Nepal and Sri Lanka. Green technology and energy efficiency technologies to use in the industries, encourage using public transportation, sustainable energy and urbanization are potential policy recommendations.

Optimal planning and multi-criteria decision making for effective design and performance of hybrid microgrid integrated with energy management strategy

The dependence on fossil fuels for energy generation resulted in severe environmental challenges, triggering green transition. As a result, there has been massive uptake of renewable energy share in the energy sector, devising new ways of generating energy. Hybrid microgrids are one such system enabling green transition in the energy sector. However, they mostly face planning and feasibility-related challenges. Such challenges become more complex when consumer’s preferences on energy use patterns are considered. Hence, this paper considers designing a hybrid microgrid considering consumer-centric energy management options. A case study has been simulated considering the consumer’s preferences on energy use patterns using a hybrid optimization of multiple energy resources tool for understanding the techno-economic-environmental feasibility through which better planning of microgrid infrastructure can be made. The results include the hybrid microgrid system architecture, capacity size optimization, energy performance and cost parameters. The observed energy potential from the optimally planned hybrid microgrid satisfied the electrical energy requirements. It is observed that the energy management option strongly influences the hybrid microgrid system architecture, capacity size optimization, and cost. Based on the observed results, the best-worst method was implemented for decision-making over the system architecture selection considering multiple decisions over techno-economic and environmental aspects.

Are characteristics of metropolis matters for structural transformation of provinces: A spatial approach in the case of Vietnam

This study analyzes the impact of metropolises on the structural transformation of provinces based on specific metropolises’ characteristics. Moran I index on the share of non-agricultural sectors in the economic structure is firstly employed to examine the spatial autocorrelation between provinces in Vietnam. Furthermore, the relationship between metropolises and the change in the economic structure of provinces is analyzed quantitatively using spatial panel data models based on data from the statistics yearbook of all 63 areas in the period 2015 to 2018. The research results confirm the role of metropolises in the process of structural transformation of the provinces. Provinces with a high proportion of non-agricultural sectors in the economic structure show the concentration around metropolises. The destination for migration, the origin of remittance, and the market for neighboring provinces, are the function of metropolises. These roles are seen as driving forces for off-farm activity through changes in the incomes of neighboring provinces. Accordingly, focusing on specific metropolises characteristics as well as enhancing regional connectivity will contribute to promoting effective provincial structural transformation.

Supporting factors for labor productivity in Indonesia

Indonesia's investment attractiveness is still weak compared to other ASEAN countries; one of the reasons is the low labor productivity. On this basis, this study aims to find out what factors are dominantly driving labor productivity in Indonesia statistically, as well as the right policy model to encourage labor productivity, bringing Indonesia a high-income country. The analytical method used in this study is panel data regression analysis, 2014 - 2018 period, covering 34 provinces in Indonesia. The study suggests that fiscal policy through general allocation fund (DAU) or transfers signifies increasing labor productivity, while special allocation fund (DAK) does not. Economic factors such as labor costs, the contribution of the agricultural sector, and economic openness can increase labor productivity, while industrial sector share has no effect. Social factors measured by the education level of general secondary schools and life expectancy (health) affect labor productivity enhancement; it is different from a vocational school. Consequently, the number of unemployed vocational school graduates is high.

The environmental impact of the Dutch health-care sector beyond climate change: an input–output analysis

Studies suggest that the Dutch health-care sector is responsible for 4-8% of the national carbon footprint, but the environmental footprint of this sector beyond climate change is not well understood. Therefore, we aimed to estimate the environmental footprint of the Dutch health-care sector for a range of environmental impact categories. In this input-output analysis, we used Exiobase (version 3), which contains data on global trade flows and their associated environmental impact, in combination with health-care expenditure data from Statistics Netherlands. We covered the impact categories: climate change, blue water consumption, abiotic material extraction, land use, and total waste generation. The calculated sectoral footprint was the sum of all impacts associated with the operational phase (direct impact) and impacts occurring in the value chain of purchased goods and services (indirect impact) given an expenditure vector. The expenditure vector was the sum of three elements of health-care expenditure: health-care services; pharmaceuticals and chemical products; and medical appliances. We calculated the impact share of health care on the total Dutch consumption footprint. We evaluated the contribution to the impact categories from the categories that composed the expenditure vector. We did a hotspot analysis in which the indirect impact was split according to where (sector, geography, or both) the impact physically occurred. These top-down results were complemented with bottom-up data on emissions from pressurised metered-dose inhalers, anaesthetic gases, and private travel. The health-care sector's share of the national footprint was highest for material extraction (13·0%), followed by blue water consumption (7·5%), climate change (7·3%), land use (7·2%), and waste generation (4·2%). Pharmaceuticals and other chemical products were the biggest contributors to all impacts. The sectors contributing to climate change were more evenly distributed than the sectors contributing to the other impact categories. The mining sector mostly contributed to material extraction and the agricultural sector contributed largely to blue water consumption and land use. The mining sector and the agricultural sector were the main contributors to waste generation. Climate change occurred mainly in the Netherlands, whereas the other impacts mainly occurred abroad. The Dutch health-care sector contributes to a broad set of environmental impact categories beyond climate change. Our results will help stakeholders involved in the health-care sector to pinpoint topics that need to be prioritised and to prevent trade-offs by addressing multiple environmental issues simultaneously.

How does ICT trade shape environmental impacts across the north-south regions? Intra-regional and Inter-regional perspective from dynamic CGE model

In today's modern economy, the source of many economic and environmental effects is due to the ICT goods trade. But the extent and type of effects on trade partners can depend on level of regional development. In this research, we evaluate the economic, environmental as well as energy intensity implications of ICT products trade across the developing (south) and developed (north) countries. To achieve this objective, we apply a dynamic computable general equilibrium model in the form of south-south, north-north and south-north trade. The results show that by increasing the ICT imports, carbon emissions, energy and carbon intensity will rise. If the ICT flow is from south to south and south to north, the intensity of the mentioned indicators will be more intense rather than north to other regions case. Intra-regional imports (north-north and south-south) increase ICT and GDP production within the regions, which leads to a positive scale effect. An increment in inter-regional imports (north-south) will lead to a reduction in ICT and GDP production in the ICT-importer region. In addition, the increase in intra-regional imports leads to composition effect to be negative and the improvement of inter-regional imports leads to a positive composition effect. Thus, south-south and north-north trade increases the share of pollution-intensive sectors. The study recommends trade of ICT products, which are environment and clean energy friendly, for both the regions.

EMPIRICAL FINDINGS ON THE RELATIONSHIP BETWEEN RENEWABLE ENERGY PRODUCTION, EXPORT DIVERSIFICATION AND CO2 EMISSIONS IN TRANSFORMATION ECONOMIES

In order to contribute to the ongoing discussions on the environment-economy relationship, the relationship between renewable energy consumption, export diversification, economic growth and CO2 emission in the countries considered as transformation economies was investigated in the period between 1997 and 2014 in the current study. In the study, IPS, LLC unit root tests, Pedroni and Kao cointegration tests, and FMOLS and DOLS coefficient estimation methods, which are frequently used in the literature, were used. As a result of the analyses, it was concluded that renewable energy consumption, economic growth and export diversification have negative effects on CO2 emissions, while trade openness has a positive effect. In the Dumitrescu-Hurlin causality test results, a bidirectional causality relationship was found between renewable energy production and trade openness and CO2 emissions. Within the scope of these results, it is considered important to implement incentive policies for export diversification and renewable energy production in countries of transformation economy. Given the positive effect of trade openness on CO2 emissions, it is considered necessary to reduce the share of sectors polluting the environment in trade and to increase the share of sectors that do not have a negative impact on the environment.

Change of Fossil-Fuel-Related Carbon Productivity Index of the Main Manufacturing Sectors in Poland

The article presents the global characteristics of the Polish manufacturing industry and the structure of its energy consumption and carbon dioxide emissions related to direct emission as a result of fuel combustion and indirect emission as a result of electricity consumption. The share of individual sectors in energy consumption and emission levels was determined, and the changes in this share over the last 20 years were determined. A method for determining the carbon productivity index for the emissions of individual industries with the use of global macroeconomic indicators was proposed. The index allows for the comparison of the productivity of individual industries, regardless of the nature of production. The change in carbon productivity in Polish industry over time was presented. On this basis, it was assessed which industries are particularly promising in terms of decarbonising the Polish industry.

The effect of social responsibility and managerial ability on firm value-mediated profitability

The mining industry in Indonesia has a high enough capitalization value to attract investment. The more investors that invest, the higher the stock price and the value of the firm, yet the mining sector's share price has changed throughout time. The mining industry in Indonesia must likewise be mindful and worried about the environment. Previous research has not explored the correlation between profitability and firm value, which contributes as a mediator. This resulted in a clear gap in the literature. This study contributes to filling a gap in the literature. The mining sector businesses listed on the Indonesia Stock Exchange (IDX) from 2018 to 2020 were chosen as the population, with a total sample of 11 companies selected using the purposive selection approach. The data analysis process has been carried out using SPSS version 28 software. The study's findings revealed that corporate social responsibility and corporate management skills had little influence on business value. Furthermore, the findings of this research show that profitability, as a moderating variable in this study, is a complete mediator of social responsibility and managerial ability to firm value. The presence of profitability mediation in this research yields substantial findings, serving as a warning to investors.

The plight of mining cities in South Africa: Planning for growth and closure

The mining sector's share in South Africa's economy has declined over the past 30 years, as has employment on the gold mines. Yet many new mining areas have developed. Mining growth has been driven primarily by platinum and coal, with iron ore and other metals contributing. Of South Africa's 39 ‘small’ or ‘secondary’ cities, 19 have or have had substantial mining economies. Whether growing and declining, they have experienced a rapid increase in informal housing, service backlogs, pressure on municipal finances, and social disruption. We assess these trends in these cities against a background of the literature on boomtowns and referring to evolutionary governance theory. We examine both local and national government responses and policies. Our sources are census and economic data, audited municipal financial statements, and crime statistics. We suggest that investigating the social disruption associated with mining decline should be the sixth phase of boomtown research. We argue that mining town planning should avoid creating long-term dependencies and focus instead on creating flexibility. Questions should be asked about the uncritical way government policy links mining and development. A more careful approach should be followed and alternative approaches to mine housing should be considered.

Are community pharmacies the best purchasing channel for cosmetic products? Prioritization of consumer preferences via analytical hierarchy process

Background and Aims: Many different purchasing channels play an essential role in meeting cosmetic product demand worldwide. These include supermarkets, cosmetic markets, community pharmacies, beauty salons, internet retailing, and shopping complexes. This study’s main objective is to prioritize consumers' cosmetic product purchasing channel preferences. The originality of this study lies in being the first study that addressed customers' choice of cosmetic product purchasing channels via the Analytical Hierarchy Process (AHP). Methods: Firstly, a questionnaire was conducted (n=287) to determine cosmetic product purchasing channel selection criteria. Cosmetic product purchasing channel alternatives were prioritized among the first questionnaire results via the AHP with 12 consumers who reside in the city center of Van, Turkey and buy at least two cosmetic products per year. Results: As a result of the study, community pharmacies (46.9%) were found to be the best alternative among the cosmetic product purchasing channels, followed by cosmetics stores (24.1%). The most important criterion affecting the selection of cosmetic product purchasing channels is satisfaction with the consultancy (25.2%), followed by advice from health care providers (22.1%). Conclusion: It has been observed that consumers prefer community pharmacies more than other purchasing channels when purchasing cosmetic products. Understanding customer needs, expectations, and experiences is vital for optimizing the quality of the offered service. Thus, pharmacies with a significant market share in the cosmetics sector can further their cosmetics services by considering the consumer demands highlighted in this study.
