The aim of this study is to investigate the long-term relationship between real gross domestic product (GDP), energy consumption (EC), and carbon dioxide (CO2) emissions using: (i) fully modified ordinary least square (FMOLS) and dynamic ordinary least square (DOLS) estimates, to deal with the bias of endogeneity regressors and the countries’ heterogeneity, and (ii) a pooled mean group (PMG) estimator, to involve both pooling and averaging for a dynamic specification based on the auto-regressive distributed lag (ARDL) model. Regarding five North African countries (Morocco, Algeria, Tunisia, Libya and Egypt) over the period of 1971–2014, our empirical findings seem relevant in the light of economic developments, and indicate that increased energy consumption gives rise to both GDP growth and increased CO2 emissions, as a result of more pollution. This leads us to conclude that North African countries should improve the productivity of their energy by increasing: (i) the implementation of energy-saving projects, energy conservation, energy efficiency, and energy infrastructure, while outsourcing to achieve GDP growth as well as increasing their investment in full-energy-potential projects, and (ii) the use of more renewable energy in order to mitigate emissions.

This study extends previous environmental sustainability literature by investigating the joint impact of economic growth and renewable energy on reducing CO2 emissions in Saudi Arabia over the period 1990–2016. Using the fully modified ordinary least-square (FMOLS) and dynamic ordinary least-square DOLS estimators, we find that economic growth increases CO2 emissions in all estimated models. Moreover, the validity of the environmental Kuznets curve (EKC) hypothesis is only supported for CO2 emissions from liquid fuel consumption. The invalidity of the EKC hypothesis in the most commonly used models implies that economic growth alone is not sufficient to enhance environmental quality. Renewable energy is found to have a weak influence on reducing the indicators of environmental degradation. We also find that the joint impact of renewable energy consumption and economic growth on the indicators of CO2 emissions is negative and insignificant for all the estimated models, meaning that the level of renewable energy consumption in Saudi Arabia is not sufficient to moderate the negative effect of economic growth on environmental quality. Implications for policy are also discussed.

This paper provides a study of the relationship between sustainable development and foreign direct investment (FDI) from an empirical point of view in the case of the North African countries during the period from 1985 to 2005. We use the cointegration test, the FMOLS (Fully Modified Ordinary Least Squares) model and the Granger causality test to examine this relationship. According to the empirical results, we confirm the existence of a cointegration relationship between the different series studied in this paper. Based on the cointegration test we can use the error correction model. Also, to test the effect of FDI on sustainable development in the North African countries, we make an estimate by FMOLS method. We found that the foreign direct investment has a positive impact on CO2 emissions. Also, the Granger Causality test confirms the presence of a bidirectional relationship between FDI and CO2 emissions (Carbon dioxide). That is to say, the FDI can cause CO2 emissions and CO2 emissions can cause FDI based on the Granger causality.

AbstractThe study of dust intrusions in Portugal is still a subject on which little investigation has been made, especially in terms of their effects. Thus, this work aims to achieve two goals: firstly, to characterize the dust intrusions in the study area; and secondly, to evaluate the possible statistical association between the dust intrusion days and hospital admissions due to respiratory diseases. Dust intrusions in Portugal are prevalent during the summer season. During this season, the dust plumes tend to cover broader areas than in the other seasons and they have origin in the North African countries. In the study area for the period between 2005 and 2015, the relative risk of urgent hospitalizations due to respiratory diseases was 12.6% higher during dust intrusion days. In order to obtain this statistical association, a Distributed Lag Nonlinear Model was developed. With this work, we expect to help the development of further studies regarding North African dust intrusions in Portugal, more precisely their effects on human health.

This paper aims to test the validity of the causality between financial development and economic growth on energy consumption in three of North African countries. The study employs error coreection model and Granger causaility test to analyza a dataset for three North African countries covering a period from 1980 to 2010. The applied model is based on demand function for energy to assess the existing of causal relationship of energy with financial development, and economic growth, in Algeria, Egypt, and Tunisia. Empirical results provide a positive significant relating financial development and energy consumption in Algeria, and Tunisia. On the other hand, Egypt’s results show a negative significant relationship relating energy consumption and financial development. The paper is valuable to policy makers in North African countries in their pursuit for achieving economic growth as it clarifies the urge for the financial development reforms to stimulate investment and growth.
