The purpose of the study is to investigate the interrelationship between corporate social responsibility (CSR) practices and green finance (GF) behavior and their collective impact on attaining sustainable tourism in Bangladesh. The study is based on a conceptual method. The relevant information is derived from different websites, publications, and research articles. The tourism industry is an emerging business industry in Bangladesh that has been gradually attracting both domestic and international tourists due to its natural and cultural heritage, diverse landscapes, and historical sites. This industry has been creating job opportunities, alleviating poverty, increasing economic growth, and helping to achieve the SDGs. However, the study found a positive impact between CSR and the adoption of green finance. It demonstrates how businesses that combine CSR practices with green finance can help Bangladesh establish a sustainable tourism industry. Moreover, the result showed that integrating CSR with green finance has encouraged sustainable tourism. In order to achieve sustainable tourism, collaboration with relevant parties has to be enhanced. An education and awareness program has to be implemented to make the business aware of the benefits of CSR practices. Tax incentives and subsidies for corporations will encourage them to engage more in green finance.

AbstractThe key objective of this study is to investigate how capital formation and technological advancement affect foreign direct investment (FDI) generation in Bangladesh and whether money circulation has a positive or negative impact on FDI. This study has used time series data from 1972–2021, and the result of the unit root test indicates an autoregressive distributed lag (ARDL) model because of stationarity at levels I(0) and I(1). The cointegration test confirms the cointegration among the variables: in the short run and long run, capital formation and technological advancement have a positive impact on FDI; on the other hand, money circulation discourages FDI because of its negative coefficient. The speed of adjustment (CointEq(−1)) is 0.28%, which indicates the estimation moves toward an equilibrium condition from a disequilibrium condition. Causality shows there is bidirectional causality between FDI and money circulation, unidirectional causality between technology and FDI, bidirectional causality between money circulation and capital formation, and unidirectional causality between technology and capital formation. This finding suggests that capital formation should be a great consideration, and technology is also required to expand FDI volume. Further study would include considering other macroeconomic variables such as labor, human resources, and energy issues.

This study looks at the short- and long-term effects of fossil fuels, renewable energy, and nuclear energy on CO2 emissions in the South Asian Association for Regional Cooperation (SAARC) countries from 1982 to 2021. We assess the impacts of SAARC’s current and anticipated use of nuclear, fossil, and alternative energies by testing the environmental Kuznets curve (EKC) hypothesis. The study applied the second-generation unit root test, cointegration test, and the newly introduced AMG technique to handle the presence of cross-sectional dependence. The results indicate that EKC does not hold in SAARC, and a U-shaped quadratic link exists between GDP and environmental pollution. The findings also reveal that the environmental pollution in the SAARC is caused by fossil fuel, whereas using renewable (REN) and nuclear energy can cut long-term pollution. While renewable energy is critical to minimizing environmental deterioration in SAARC, empirical findings also show that more than rising national wealth is needed to meet environmental demands. According to the results of this study, SAARC countries should take the lead in achieving sustainable growth and the efficient use of clean energy.

ABSTRACTThe child mortality rate for children under five years of age is a major problem worldwide. The purpose of this study is to investigate the factors responsible for controlling the under-5 mortality rate in G-7 countries. The study utilized monthly time series data from 1971 to 2021 and employed Grossman’s health production function with Driscoll-Kraay’s standard error estimation approach for all statistical analyses. The results showed that economic expansion and the use of renewable energy contribute to the reduction of under-5 mortality rates in G-7 countries, whereas fossil fuels, industrialization, education, and unemployment contribute to the increase in mortality rates. The robust results also revealed that GDP, renewable energy, and education help mitigate under-5 mortality rates in G-7 countries. This analysis plays an essential role in helping G-7 countries reduce their under-5 mortality rates while considering environmental sustainability. Additionally, the required discussions and policy recommendations are also presented.

Climate change resulting from increasing emissions has become a pressing concern in North African countries due to its significant environmental and socio-economic impacts. There is a need for extensive research on this topic to raise global awareness of the associated dangers. This study investigates the dynamic impact of economic growth, military expenditure, globalization, renewable energy, manufacturing, tourism, capital formation, and labor on CO2 emissions in North African countries from 1995 to 2021. The long-term results of the ARDL model reveal that globalization, renewable energy and capital formation have a negative impact on CO2 emissions, whereas economic growth, manufacturing, and tourism exhibit a positive impact. Pairwise Granger causality evidence indicates unidirectional causality from economic growth, globalization, military expenditure, manufacturing, tourism, and capital formation to CO2 emissions. These findings provide policymakers with critical insights to shape evidence-based interventions that promote renewable energy investments and globalization, enhance capital formation and high-skilled labor, and implement regulations to mitigate the environmental impacts of economic growth, military expenditure, manufacturing, and tourism. This guidance will help the region transition to a more environmentally friendly economic system.

This study examines the role of green financing and energy production to mitigate climate change in emerging economies like Bangladesh. In today’s world, climate change is a significant issue that impacts humans on an environmental, social, and economic level. However, this study aims to explain how to mitigate climate change with the support of green finance and green energy in Bangladesh. The study uses mixed methods to conduct the research, such as quantitative and qualitative methods. In this particular case, the study identified several crucial factors that contribute to the effects of climate change. Two environmentally friendly tools, like green finance and green energy, are used to fight climate change. Green finance, comprising financial instruments like green bonds and loans, finances significant investments in environmental projects, particularly renewable energy, that promote the transition to a greener, low-carbon economy and ultimately help to combat climate change. Solar, wind, hydropower, biomass, and biofuels are the common green energy production technologies in Bangladesh, which can play a pivotal role in reducing climate change by reducing greenhouse gas emissions. In Bangladesh, green finance contributes to investment in green energy projects, innovation in clean energy technologies, investment risk management, and energy transitions, according to the research. The study suggests valuable implications for the Bangladesh government, policymakers, and other policymakers taking effective initiatives to protect Bangladesh from the gulf of devastating climate change.

The main purpose of this study was to examine how tourism, GDP, renewable energy, and fossil fuels cause environmental damage. This study examined ten African countries between 1997 and 2021 to test the environmental Kuznets curve (EKC) theory. Egypt, South Africa, Kenya, Morocco, Tanzania, Tunisia, Mauritius, Ghana, Uganda, and Nigeria are the ten African countries with the most tourists. In this paper, the augmented mean group (AMG), mean group (MG), and common correlated effects mean group (CCEMG) models were used to deal with slope heterogeneity (SH), cross-sectional dependence (CSD), and a mix of first-differenced and level stationary variables. Though the inverted U-shaped exists, the findings are significant only for MG. The impact of renewable energy is favorable for the environment and significant for the AMG estimator. Inversely, impact of tourist arrivals and fossil fuels are detrimental for environment and significant. Based on the findings for each country, the tourism-based EKC theory only works for Kenya, Egypt, and Tanzania. The research found that using more renewable energy minimizes CO2 emissions more effectively in almost all countries except Morocco and Ghana. Ghana, Kenya, and Uganda’s CO2 emissions increase when more tourists come from other countries. For the sake of both tourism and the environment, the government must reconsider its tourism policies and implement ones that include renewable energy. The findings of this study assist in the transition to clean energy, aiding in sustainable tourism growth. As a result, selected countries should develop a new tourism plan that focuses on renewable energy sources and protects the environment.

Les effets de l'extrait éthanolique de graines de Trigonella foenum-graecum (fenugrec) sur la glycémie chez des rats diabétiques induits par l'alloxane à différentes doses (2 g/kg, 1 g/kg, 0,5 g/kg et 0,1 g/kg) ont été étudiés. L'effet hypoglycémiant de l'extrait a été comparé à celui de la dose unique du médicament antidiabétique standard (glimépiride, 4 mg/kg). L'extrait a montré une activité significative contre l'état diabétique induit par l'alloxane mais l'intensité de l'effet hypoglycémique variait d'une dose à l'autre. La dose la plus efficace reconnue était de 1 g/kg, mais elle reste inférieure à celle du médicament antidiabétique standard. Aucune toxicité aiguë n'a été observée pour l'extrait éthanolique de graines de T. foenum-graecum lorsqu'il a été administré par voie orale à une dose élevée (3 g/kg de poids corporel), ce qui est supérieur à la dose antihyperglycémique efficace, et observé de près pendant 24 heures pour toute mortalité et les 10 prochains jours pour tout effet toxique retardé sur les activités comportementales brutes. Des tests de groupes phytochimiques ont également été réalisés et la présence d'alcaloïdes, de stéroïdes et de glucides a été reconnue dans l'extrait. Se estudiaron los efectos del extracto etanólico de semillas de Trigonella foenum-graecum (fenogreco) sobre los niveles de glucosa en sangre en ratas diabéticas inducidas por aloxano a diferentes dosis (2 g/kg, 1 g/kg, 0,5 g/kg y 0,1 g/kg). El efecto hipoglucémico del extracto se comparó con el del fármaco antidiabético estándar (glimepirida, 4 mg/kg) en dosis única. El extracto mostró una actividad significativa contra el estado diabético inducido por aloxano, pero la intensidad del efecto hipoglucémico varió de una dosis a otra. La dosis más eficaz reconocida fue de 1 g/kg, pero sigue siendo inferior a la del fármaco antidiabético estándar. No se observó toxicidad aguda para el extracto de etanol de la semilla de T. foenum-graecum cuando se administró por vía oral a un nivel de dosis alto (3 g/kg de peso corporal), que es más alto que la dosis antihiperglucémica efectiva, y se observó de cerca durante 24 horas para cualquier mortalidad y los próximos 10 días para cualquier efecto tóxico retardado en las actividades de comportamiento grave. También se realizaron pruebas de grupos fitoquímicos y se reconoció la presencia de alcaloides, esteroides e hidratos de carbono en el extracto. The effects of ethanol extract of Trigonella foenum-graecum (Fenugreek) seeds on the blood glucose levels in alloxan-induced diabetic rats at different doses (2 g/kg, 1 g/kg, 0.5 g/kg and 0.1 g/kg) were studied. The hypoglycemic effect of extract was compared with that of the standard antidiabetic drug (glimepiride, 4 mg/kg) single dose. The extract showed significant activity against the diabetic state induced by alloxan but the intensity of hypoglycemic effect varied from dose to dose. The most effective dose recognized was 1 g/kg but that is still lower than the standard antidiabetic drug. No acute toxicity was observed for ethanol extract of T. foenum-graecum seed when it was administered orally at high dose level (3 g/kg body weight), which is higher than effective antihyperglycemic dose, and closely observed for 24 hrs for any mortality and next 10 days for any delayed toxic effects on gross behavioral activities. Phytochemical group tests were also accomplished and presence of alkaloids, steroids and carbohydrates were recognized in the extract. تمت دراسة تأثيرات مستخلص الإيثانول من بذور Trigonella foenum - graecum (Fenugreek) على مستويات الجلوكوز في الدم في الجرذان المصابة بالسكري التي يسببها الألوكسان بجرعات مختلفة (2 جم/كجم، 1 جم/كجم، 0.5 جم/كجم و 0.1 جم/كجم). تمت مقارنة تأثير نقص السكر في الدم للمستخلص مع تأثير الدواء القياسي المضاد لمرض السكري (غليميبيريد، 4 ملغ/كغ) جرعة واحدة. أظهر المستخلص نشاطًا كبيرًا ضد حالة السكري الناجمة عن الألوكسان، لكن شدة تأثير نقص السكر في الدم اختلفت من جرعة إلى أخرى. كانت الجرعة الأكثر فعالية التي تم التعرف عليها هي 1 جم/كجم ولكن هذا لا يزال أقل من الدواء القياسي المضاد لمرض السكري. لم يلاحظ أي سمية حادة لمستخلص الإيثانول من بذور T. foenum - graecum عندما تم إعطاؤه عن طريق الفم بمستوى جرعة عالية (3 جم/كجم من وزن الجسم)، وهو أعلى من الجرعة الفعالة المضادة لارتفاع السكر في الدم، وتمت ملاحظته عن كثب لمدة 24 ساعة لأي وفيات والأيام العشرة التالية لأي تأثيرات سامة متأخرة على الأنشطة السلوكية الإجمالية. كما تم إجراء اختبارات المجموعة الكيميائية النباتية وتم التعرف على وجود القلويدات والستيرويدات والكربوهيدرات في المستخلص.
