Abstract. The Indian economy has grown significantly during the past decades. Satellite-based remote sensing enables atmospheric pollution to be observed globally, in remote regions, and in regions where the infrastructure for air quality monitoring is limited. Here, we investigate the temporal evolution of tropospheric nitrogen dioxide (NO2) since the early 2000s, and correlate NO2 abundances with indicators of economic development, notably gross state domestic product and electricity generation capacity, for all 35 Indian states and union territories. From 2003–2012, NO2 pollution and economic growth are strongly correlated, leading to annual increases of up to 4.4 %. This increase is strongest in states in East India having heavy industry. In 2012, the amount of tropospheric NO2 reached a maximum; since then, tropospheric NO2 pollution has stabilized or is even declining. While the Indian economy continues to grow, this decline in observed NO2 values may be a result of a slow-down in Indian economic growth, combined with the implementation of cleaner technology. Additionally, we identify regional pollution sources such as individual steel smelters and the cement industry, which are severely degrading air quality. In Tamil Nadu, economic growth has not led to increasing NO2 columns, which we attribute to the investment in the development of renewable energy sources during the 2000s.

The growth of renewable energy sources (RES) shows the desire of the government of Kazakhstan to meet challenges that affect the welfare and development of the state. National targets, government programs, policies influence renewable energy strategies. In the future, renewable energy technologies will act as sources of a green economy and sustainable economic growth. The state policy in the field of energy in Kazakhstan is aimed at improving the conditions for the development and support of renewable energy sources, amendments are being made to provide for the holding of auctions for new RES projects, which replaces the previously existing system of fixed tariffs. It is expected that the costs of traditional power plants for the purchase of renewable energy will skyrocket, provided that the goals in the field of renewable generation are achieved. This article provides an assessment of international experience in supporting renewable energy sources, as well as analyzes the current situation in the development of renewable energy in Kazakhstan and the impact on sustainable development and popularization of the «green» economy. The study shows that by supporting the development of renewable energy sources, economic growth is possible, which is achieved in an environmentally sustainable way.

Purpose – The purpose of this paper is to investigate the impact of financial development, economic growth and energy consumption on environment degradation for Indian economy by using the time series data for the period 1971-2011. Design/methodology/approach – The stationary properties of the variables are checked by ADF, DF-GLS, PP and Ng-Perron unit root tests. The long-run relationship is examined by implementing the Autoregressive Distributed Lag bounds testing approach to co-integration and error correction method (ECM) is applied to examine the short-run dynamics. The direction of the causality is checked by VECM framework and variance decomposition is used to predict exogenous shocks of the variables. Findings – The empirical evidence confirms the existence of long-run relationship among the variables. Financial development appears to increase environmental degradation in India. The main contributors to environmental degradation are: economic growth, energy consumption financial development and urbanization. The results also lend support to the existence of environmental Kuznets curves for Indian economy. Research limitations/implications – The present study suggests that environmental degradation can be reduced at the cost of economic growth or energy efficient technologies should be encouraged to enhance the domestic product with the help of financial sector by improving environmental friendly technologies from advanced economies. Originality/value – This paper proposes to make a contribution to the existing literature through examining the relationship between financial development and environmental degradation in Indian economy during 1971-2011 by employing modern econometric techniques.

This paper tries to shift the focus of research on the impact of natural disasters on economic growth from global and national levels to sub-national levels. Inadequate sub-national level information is a significant lacuna for planning spatially targeted climate change adaptation investments. A fixed-effect panel regression analyses of 19 states from 2001 to 2015 assess the impacts of exposure to floods and droughts on the growth of gross state domestic product (GSDP) and human development index (HDI) in India. The flood and drought exposure are estimated using satellite data. The 19 states comprise 95% of the population and contribute 93% to the national GDP. The results show that floods indeed expose a large area, but droughts have the most significant impacts at the sub-national level. The most affected GSDPs are in the non-agriculture sectors, positively by the floods and negatively by droughts. No significant influence on human development may be due to substantial investment on mitigation of flood and drought impacts and their influence on better income, health, and education conditions. Because some Indian states still have a large geographical area, profiling disasters impacts at even smaller sub-national units such as districts can lead to effective targeted mitigation and adaptation activities, reduce shocks, and accelerate income growth and human development.

Abstract This paper targets to examine the impact of renewable energy and ecological footprint on economic growth in 14 selected French-speaking countries in Africa. The study contributes to the ongoing debate in the literature on environment growth-nexus by providing evidence that economic growth emerges with environmental degradations and can be improved when there is a robust institutional framework. The present research used the generalized method of moments (GMM) to assess a dynamic growth model with data from 2007 to 2015. The results demonstrate that renewable energy is significant and negatively related to economic growth, which implies that renewable energy sources lower the per capita income growth in these countries. Meanwhile, the ecological footprint is positive and statistically significant in impacting economic growth in the long run. For institutions, we find that voice and accountability, political stability, and the rule of law are positive and statistically significant in influencing economic growth. Consequently, it is recommended that policymakers in this region develop dual policies that raise institutions' quality with minimal emissions of greenhouse gases.

The paper explores the impact of good governance on human development in India during the last two decades. Using panel data analysis, it finds the evidence that good governance and past human development determines present human development in India. That means good governance can be considered as the policy variables through which we can obtain high economic growth and human development in the country. The paper accordingly suggests that with better institutional mechanism and good governance the country can put its development process in the higher ladder of growth and human development. The lack of same may affect the development process, particularly to achieve sustainable economic growth and human development. Hence governments should have aim to increase the status of good governance and can maintain the same with greater caution. This is not a daunting task, if there is adequate political will in the economy.


The purpose of this research is to examine the impact of reforms that took place in Indian economy in 1991. Balance of payment difficulty resulted in acute economic crisis and therefore economic reforms were inevitable. Post this incident; there have been three more phases of economic reforms. Economic reforms were compelled due to international pressure of the situation post balance of payment crisis of 1991. The significance of this study lies in the derivation of various ways in which these reforms played a major role in the transformation of Indian economy in the form of its impact on poverty, education, socio-cultural mixture, economic growth etc. We have tried to revisit situation of payments crisis and tried to understand if these reforms were enough and were they concrete measures to tackle long-term problem or if they were only sufficient to handle the crisis. Finally we have tried to find out, as to what was left out of reforms or what other measures could have been taken. Balance of payment difficulties are difficulties faced by most of the underdeveloped or developing countries

The nature of the relationship between income inequality and economic growth, first formalised by Simon Kuznets in 1950, has come under much debate of late. At present, one understanding of this relationship is that given by what Oded Galor called the ‘modern perspective’, which, pointing the direction of causation from income inequality to economic growth asserts that the former imposes a significantly negative influence on the latter. To investigate the same in the context of India, subsequently, this study adopts the typical cross-country approach taken by other studies in this area and estimates the nature of the aforementioned relationship across a cross-section of Indian states. The results, however, disappointingly contrary to the ‘modern perspective’, show a strong significant positive impact of the existence of inequality on growth rates of Indian states, which, if anything, statistically asserts the existence of a trade-off between the two.

Energy is one of the most important drivers of economic growth, but as the population is increasing, in normal circumstances, in all countries of the world, there is a demand for energy produced from conventional resources. Increasing prices of conventional energy and the negative impact on the environment are two of the main reasons for switching to renewable energy sources (RESs). The aim of the paper is to quantify the impact of the RESs, by type, on the sustainable economic growth at the European Union (EU) level. The research was performed for all 28 EU member states, for a time frame from 2004 to 2017, through a panel autoregressive distributed lag (ARDL) approach and causality analysis. Furthermore, Hausman test was performed on the regression model. By estimating the panel data regression model with random effects, we reveal through our results that RESs, namely wind, solar, biomass, geothermal, and hydropower energy, have a positive influence on economic growth at EU level. Moreover, biomass has the highest impact on economic growth among all RES. In fact, a 1% increase in biomass primary production would impact the economic growth by 0.15%. Based on econometric analysis, our findings suggest that public policies at the EU level should be focused on investment in RESs.

Purpose The purpose of this paper is to examine the impact of female human capital on economic growth in the Indian economy during 1970-2014. Design/methodology/approach The paper employs Ng-Perron unit root test to check the order of integration of the variables. The study also used ARDL-bounds testing approach and the unrestricted error-correction model to investigate co-integration in the long run and short run; Granger’s causality test to investigate the direction of the causality; and variance decomposition test to capture the influence of each variable on economic growth. Findings The study constructed a composite index for both male and female human capitals by taking education and health as a proxy for human capital. The empirical findings reveal that female human capital is significant and positively related to economic growth in both short run and long run, while male human capital is positive but insignificant to the economic growth; same is the case for physical capital, it implies that such investment regarding female human capital needs to be reinforced. Further, there is an evidence of a long-run causal relationship from female human capital, male human capital and physical capital to economic growth variable. The results of variance decomposition show the importance of the female human capital variable is increasing over the time and it exerts the largest influence in change in economic growth. Research limitations/implications The empirical findings suggest that the Indian economy has to pay attention equally on the development of female human capital for short-run as well as long-run growth of the economy. This implies that the policy makers should divert more expenditure for developing support for female education and health. Originality/value To the best of authors’ knowledge, this is the first attempt to study the relationship between female human capital and economic growth in the context of the Indian economy.
