Microbial Growth Rate Kinetics in Biogas Production by Anaerobic Digestion of Chicken Manure
Get PDFKinetic study of microorganism’s growth in chicken manure (CM) when producing biogas is often studied for scale-up purposes. CM is considered as waste and can cause serious environmental consequences when not properly disposed of. The objective of the study is to know the characteristics of the bioreactor condition or environment responsible for CM degradation and biogas production. Methods involve serial dilution, pour plating, cell count, and the determination of Monod parameters. POLYMATH regression results show that CM of particle density 0.0163 g/cm3 gives a maximum specific growth rate, ?_max of 0.007316 hr^(-1) and half saturation constant, K_s of 3.8×?10?^8mg/l which points to substrate sufficiency for the survival of microorganisms and biogas production
Green Energy and Economic Growth Influence on Reducing Environmental Degradation: Empirical Evidences from China
Get PDFRecently, environmental degradation has gained global attention due to the high carbon (CO2) emission and needs the researchers and regulators to focus control this global issue. Thus, the current article investigates the impact of green energy and economic growth on environmental degradation in China. The data was extracted from a secondary source like world development indicators (WDI) from 1981 to 2018. The present article has also used the "Augmented Dickey-Fuller" (ADF) test to examine the stationarity and the "Autoregressive Distributed Lag" (ARDL) model to explore the linkage among variables. The results indicated that green energy negatively correlates with environmental degradation and economic growth, and inflation is positively linked with China\u27s environmental degradation. This study guides the relevant authorities to control ecological degradation using green energy
Globalization, Energy Use and Environmental Degradation in Thailand
Get PDFGlobalization is a crucial determinant of energy consumption, so this study analyzes the effect of energy consumption in the presence of globalization on environmental degradation in Thailand. Furthermore, this study uses the EKC hypothesis. It estimates the effect of energy use, globalization, and economic growth with the dynamics of rising or falling influence in global economic degradation and Validation of the EKC hypothesis in Thailand. For this purpose, use time-series data from 1970 to 2018. First of all, check the order of integrating the variables by the Augmented Dickey-Fuller and Phillips Perron test. Results indicate that there exists a unit root at the level. Hence move the DOLS and ARDL econometrics model to analyze the impact of globalization, energy use and economic growth on environmental degradation. Results confirm the validity of the EKC hypothesis in Thailand due to positive and negative association among the GDP and Square of GDP, which also confirms that the U-shaped relationship exists there. Thus, globalization condenses environmental degradation while energy consumption boosts the level of carbon emission in Thailand. Therefore, the study suggested that their needs improvement in energy policies reduce the use of conventional energy resources and move towards modern energy like nonrenewable energy, which reduces the pollution in the country and boosts the economic development level
Analysis of Factors Affecting Renewable Energy Consumption Evidenced from Thailand
Get PDFIn Thailand, renewable energy is an essential component in the choice of low-emissions economy growth. This study aims to investigate the factors of renewable energy consumption in Thailand. The data has been analyzed from 1980 to 2018 to identify the influencing factors for the overall energy use of renewable energy in Thailand using the Autoregressive Distributive Lag model (ARDL). The results demonstrate that renewable energy has a long-term relationship with fossil fuel consumption, financial expansion, foreign direct investment, trade openness, and GDP per capita. Further economic and financial development boosts renewables consumption of energy in Thailand. At the same time, trade and non-renewable energy (use of fossil fuel) detract from renewables consumption of energy. Hence the government of Thailand should elaborate on strategies that can increase the renewable energy amount because renewable energy plays a significant role in economic development without affecting the environment. It also increases the share of renewable energy in total energy consumption but less than renewable energy consumption
Gas- and Coal-based Power Generation to Spur Economic Growth in Pakistan?
Get PDFEnergy consumption—in all its forms (traditional, transitional, and modern)—is the lifeline of an economy as well as of a society. Electrical energy (power) is the modern form of energy that is produced from hydel, thermal, nuclear, and other sources. Gas, oil, and coal are the thermal sources of electricity generation. Literature has validated the coal and natural gas consumption-led growth hypothesis for Pakistan. Based on time series data taken for the period 1987-2019, the present study attempts to explore the economic growth implications of oil-, gas-, and coal-consumption in power sector in Pakistan. The data was obtained from World Development Indicators (WDI) and from the Pakistan Economic Survey (PES). Three econometric models were specified to check the short-run and long-run effects of energy consumption (in the form of oil, gas and coal) in power sector on economic growth. Auto-regressive Distributed Lag Model (ARDL) was used for empirical analysis. The results show that the consumption of gas and coal in the power sector have a positive and statistically significant effects on the economic growth of Pakistan. The study advocates for more reliance on gas and coal in power generation as compared to oil for economic growth in Pakistan
The Role of Green Energy on Reducing the Carbon Emission in ASEAN Countries
Get PDFRecently, carbon (CO2) emissions have become a global problem that needs attention from researchers and regulators. Therefore, the current study examines the impact of green energy on CO2 emissions in ASEAN countries. The current study has used energy import as the control variable. The present research has used secondary data collected from “world development indicators” (WDI) from 2001 to 2018. The current article has used the fixed-effect model (FEM) to test the linkage among constructs. The results revealed that green energy and energy import are negatively associated with CO2 emission. The study provides help to the policymakers while formulating policies related to controlling CO2 emissions
Climate Change and Agricultural Production in Pakistan
Get PDFAgriculture sector holds great value for Pakistan. Climate change is a major determinant of agricultural productivity all over the world. This sector is the most vulnerable sector to weather change. The productivity of this sector is being affected by several factors of climate change like temperature and rainfall patterns. The core objective of the study is to determine the impact of climate change on agricultural production (wheat, rice, and sugarcane) in Pakistan. Time series data from 1985–2018 is taken from the Pakistan Economic Survey, Metrology department of Pakistan, and the World Bank for the current analysis. Autoregressive Distributed Lag model is used to analyze the impact of climate change on agricultural production in Pakistan. The results show that climate change has an influential impact on agricultural production in Pakistan. The increase in mean temperature reduces agricultural production while the rain positively affects agricultural production. It is suggested that the government should give subsidies on agrarian tools, seeds, and fertilizers
The Effect of Tourism, Economic Growth and Environment in Developing Countries
Get PDFThe basic purpose of this study is to identify a link concerning tourism, pecuniary expansion, and environmental protection in developing countries. The current research looks at the overall state of emerging economies as well as income comparisons. The study employs the 3sls model. Tourism benefits from economic growth as well. Tourism is attracted by economic prosperity, and tourism will increase tourism. According to the findings, economic growth has a negative impact on the environment, and the environment has an adverse effect on economic growth. As income activity accelerates, so will environmental emissions, and environmental emissions have a detrimental impact on economic growth? Further findings imply that tourism has a favorable impact on the environment, with an increase in tourism causing a depreciation of the ecosystem. Environmental pollution has a favorable effect on tourism, as the majority of people travel to other countries for business and religious reasons. This can be found in all models. The exchange rate has a negative influence on the overall and high-income groups, but a favorable effect in the reduced groups. In all models, the other variable, political instability, has a negative effect on tourism, while trade has a favorable effect. GDP is boosted by the literacy rate and gross capital formation Population increase, urbanization, and energy use all have a favorable impact on environmental emissions, according to the study. According to the findings, host nations should not only encourage tourism, but also guarantee that the environment is not harmed, therefore ecofriendly must be pushed to maintain a seamless and sustainable development process
Impact of Modernized Agriculture and Trade on Carbon Emissions: The Role of Fossil Fuel and Renewable Energy Consumption Evidenced from ASEAN States
Get PDFSustainable development goals developed to reduce the level of climate transformation and its effects, this study explores the causal association between aggregate energy consumption resources, trade liberalization, CO2 emissions, and modern agriculture in selected ASEAN nations from 2000 to 2018 with the help of panel FMOLS (fully modified ordinary least square). Empirical findings have shown that the value addition level of agricultural products minimizes CO2 emissions in those countries where pollution is high. And found a positive relationship between energy consumption and CO2 emissions. Trade liberalization has made it possible to reduce CO2 emissions in economies where environmental pollution is getting lower. While the use of fossil fuels has intensified CO2 emissions, renewable energy consumption has confirmed positive effects on the pollution of the environment. While Climate-smart agriculture preferred institutions to raise income and productivity, adjusting to climate change sustainably leads to decreased greenhouse gas emissions. For example, new energy resources, renewable energy help keep the environment clean and healthy. It avoids excessive dependency on fossil fuel energy for the determinants of the agriculture sector. On the other hand, Trade policy can motivate the flow of investment opportunities and technology for a specialty in economies of scale and production. Therefore, examining strategies that encourage the agricultural sector\u27s productivity and creating active markets for international trade in ASEAN countries will improve living standards and keep the environment clean and healthy
Impact of Renewable Energy Consumption and Health Expenditure on Air Pollutants: Implications for Sustainable Development in ASEAN Countries
Get PDFThis study examined the association between economic development and environmental degradation in the presence of health expenditure and renewable energy for selected 6 ASEAN nations covering the time span of 2000 to 2018. Before estimating the model, firstly check the stationary of variables for this purpose Levin Lin Chu unit root applied, results indicate that all variables are stationary at level. GMM is efficient in eliminating fixed/random effects in the model and also overcome the problem of endogeneity in the model. For causal analysis used Granger causality test and results indicates that there exists a bi-directional association among the consumption of energy and carbon emission. There exits uni-directional association exists among Economic development, expenditure on health and environmental degradation. GMM results indicate that spending on the health sector and the consumption of renewable energy sectors decline the environmental degradation level; on the other hand, economic growth boosts the ASEAN nations\u27 carbon emission level. The recommendation of the study is to increase the level of economic development by enhancing the energy sector from non-renewable energy to renewable energy because it boosts the level of economic growth, which ultimately improve the health development and technologies which will strengthen the health facilities in the nation and also reduce the level of carbon production that helps to keep the environment healthy and clean
