    Dynamic association between ICT, renewable energy, economic complexity and ecological footprint: Is there any difference between E-7 (developing) and G-7 (developed) countries?
    (Elsevier Sci Ltd, 2022) Huang, Yongming; Haseeb, Mohammad; Usman, Muhammad; Ozturk, Ilhan
    This empirical research scrutinizes the nexus between information and communication technologies (ICT), renewable energy, economic complexity, human capital, financial development, and ecological footprint for E-7 and G-7 countries over the period from 1995 to 2018. We use four variables (Mobile cellular subscription, fixed broadband subscription, fixed telephone subscription, Internet consumers) for the ICT index prepared through principal component analysis. For empirical analysis, after testing the cross-sectional dependency, this study performs the second-generation method. From the E-7 countries' perspective, the empirical results reveal that ICT, economic complexity, and human capital increase the pollution level while renewable energy significantly reduces it. The estimated financial development coefficient is established to be statistically insignificant. In G-7 countries, all potential factors significantly improve the environmental quality except financial development. Moreover, the interaction between ICT and human capital significantly reduces the ecological footprint level in both panel countries. Therefore, we can observe that there is a wide discrepancy in these countries. The only common thing is that in these countries, bidirectional causality is discovered between ICT, human capital, and ecological footprint. Based on these empirical findings, several practice policy implications for ICT, renewable energy, economic complexity, human capital, financial development, and ecological footprint are discussed.

    Environmental pollution and agricultural productivity in Pakistan: new insights from ARDL and wavelet coherence approaches
    (Springer Heidelberg, 2022) Ramzan, Muhammad; Iqbal, Hafiz Arslan; Usman, Muhammad; Ozturk, Ilhan
    The most serious challenge to the global facade is figuring out how to mitigate pollution levels without compromising agricultural productivity. The spillover effect of environmental change is predicted to be very high, although it will differ by region and crop. Considering this view, this study tries to address this issue by adopting comprehensive methodologies to assess the influence of carbon dioxide (CO2) emissions, agricultural labor, land, feeds, and fertilizers on agricultural productivity in Pakistan from 1961 to 2018. The autoregressive distributive lag (ARDL) and wavelet transform coherence (WTC) approaches are applied to estimate the long-run and short-run elasticity estimates. The empirical findings discover that CO2 emissions, agricultural land, labor, feed, and fertilizers exert high pressure on agricultural productivity which is backed up by the WTC findings. Furthermore, the gradual shift causality test results reveal the presence of a unidirectional causality relationship between all regressors and agriculture productivity, demonstrating that all the factors significantly influence agriculture productivity. Moreover, these findings are robust to different robustness tests that we perform to test the reliability/accuracy of our core results. From policy perspectives, regulations must be developed to explore a practicable expansion strategy that includes the use of efficient fertilizers and feed at optimal levels, as well as environmental protection through public-private investment in the agricultural sector.

    Linking nuclear energy, human development and carbon emission in BRICS region: Do external debt and financial globalization protect the environment?
    (Korean Nuclear Soc, 2022) Sadiq, Muhammad; Shinwari, Riazullah; Usman, Muhammad; Ozturk, Ilhan; Maghyereh, Aktham Issa
    Nuclear energy has the potential to play an influential role in energy transition efforts than is now anticipated by many countries. Realizing sustainable human development and reducing global climate crises will become more difficult without significantly increasing nuclear power. This paper aims to probe the role of nuclear energy, external debt, and financial globalization in sustaining human devel-opment and environmental conditions simultaneously in BRICS (Brazil, Russia, India, China, and South Africa) countries. This study applied a battery of second-generation estimation approaches over the period from 1990 to 2019. These methods are useful and robust to cross-countries dependencies, slope heterogeneity, parameters endogeneity, and serial correlation that are ignored in conventional ap-proaches to generate more comprehensive and reliable estimates. The empirical findings indicate that nuclear energy and financial globalization contribute to human development, whereas external debt inhibits it. Similarly, financial globalization accelerates ecological deterioration, but nuclear energy and external debt promote environmental sustainability. Moreover, the study reveals bidirectional feedback causalities between human development, carbon emissions and nuclear energy consumption. The study offers useful policy guidance on accomplishing sustainable and inclusive development in BRICS countries.(c) 2022 Korean Nuclear Society, Published by Elsevier Korea LLC.
