Environmental quality, healthcare and research and development in Saudi Arabia

Evaluating the impact of digitalization, renewable energy use, and technological innovation on load capacity factor in G8 nations

Ecosystems are in danger due to human-caused air, water, and soil pollution, so it is important to find the underlying causes of this issue and develop practical solutions. This study adds to environmental research gap by suggesting the load capability factor (LCF) and using it to look at the factors affectting environmental health. The load capacity factor simplifies monitoring environmental health by illustrating the distinction between ecological footprint and biocapacity. We examine the interplay between mobile phone users (Digitalization DIG), technological advancements (TEC), renewable energy use, economic growth, and financial development. This study assesses G8 economies' data from 1990 to 2018, using a Cross-Section Improved Autoregressive Distributed Lag CS-ARDL estimator and a cointegration test. The data shows that green energy, TEC innovation, and DIG are all beneficial for natural health. Based on the results of this study, the G8 governments should focus on environmental policies that promote economic growth, increase the use of renewable energy sources, guide technological progress in key areas, and encourage the development of digital information and communications technologies that are better for the environment.

Dynamic effect of exchange rate depreciation on carbon emission in the Mediterranean basin: fresh insights from linear and non-linear ARDL approaches

The key objective of this study is to explore the relationship between economic growth, renewable and non-renewable energy consumption, exchange rate variation, and environmental pollution by carbon dioxide (CO₂) emissions in 19 coastline Mediterranean countries over the period 1995-2020. We suggest the application of two different approaches, namely, the symmetric autoregressive-distributed lag (ARDL) and the non-linear ARDL (NARDL) model. These methods distinguished from traditional ones by the fact that they assess both the long and short run dynamics among variables. More importantly, the NARDL method is the only technique enabling us to test the asymmetric effects of a shock in independent variables on dependent ones. Our results indicate that the long-term pollution is positively correlated with exchange rate for developed countries and negatively correlated for developing ones. Since environmental degradation in developing countries is more vulnerable to any fluctuation in exchange rate, we suggest that policymakers in Mediterranean developing countries must pay more attention to exchange rate variation as well as boosting renewable energy consumption in order to decrease CO₂ emissions.

Impacts of health expenditures and environmental degradation on health status—Disability-adjusted life years and infant mortality

Introduction

Human health and well-being are intimately related to environmental quality. In this respect, the present study contributes to the existing health economic literature by examining whether public and private health expenditures (PPHE) moderate the incidences of environmental degradation on the health status in Saudi Arabia, particularly disability-adjusted life years (DALYs) and infant mortality.

Methods

Using the fully modified ordinary least squares (FMOLS) method.

Results and Discussion

The empirical results revealed that (i) unconditional positive impacts of CO2 emissions on increasing DALYs and infant mortality; (ii) conditional negative impacts of public health expenditures on DALYs and infant mortality in all the estimated models, whereas global and private expenditure contribute only on reducing infant mortality; (iii) public health expenditure is more effective than private health expenditure in reducing infant mortality; (iv) the effects of the interactions between the indicators of both health expenditures and CO2 emissions on DALYs and infant mortality are negative and significant only for the specifications relating to public health expenditures, indicating that this later could be employed as a policy or conditional variable that moderates the adverse impacts of carbon emissions on the population’s health status. Generally, the study presents an overview of environmental health change’s effects and examine how these effects may be reduced through increasing health spending. The study provides recommendations for addressing health status, health expenditures, and carbon emissions, all of which are directly or indirectly linked to the study.
