With the exemption of Canada, the G‐7 countries have largely flourished at the detriment of their ecological sustainability bearing in mind that these countries' have remained ecologically deficit for several decades. Given the potential effect of environmental degradation associated with the trend of ecological deficit of these countries, this study attempts to understand the contribution of renewable energy dimensions through the measure of renewable energy efficiency and renewable energy use alongside evaluating the role of the four main aspects of economic freedom. By using empirical tools, the findings revealed that renewable energy aspects contribute to environmental sustainability among the countries through a significant mitigation of their ecological footprint. Importantly, the aspects of economic freedom, that is, government size, legal system and property rights, freedom to trade internationally, and regulation hampers environmental sustainability by increasing the countries ecological footprint. The elasticity of impact of this dimension of economic freedom is in the range of 0.19–0.21 at 1% statistically significant level. However, population of these countries does not show a detrimental effect, rather the finding revealed that population improves environmental quality by a statistically significant degree. Given these revelations, there are deducible policy take home from this study. [ABSTRACT FROM AUTHOR]

The study analyzed the response of agricultural growth to foreign direct investment and public agricultural spending from 1980 to 2018. Data were collected from secondary sources and analyzed using Johansen Co integration, Vector Error correction model and Monte Carlo Simulation. The result showed that foreign direct investment and public agricultural spending increased agricultural production in the long but decreased it in the short run. The study concluded that an increase in foreign direct investment and an increase in public agricultural spending (scenario 3) provided the best alternative for the sustainability of agricultural growth in Nigeria. It was recommended friendly business policies should be made to attract more foreign direct investment into the country and the issues of insecurity and infrastructures should be handled for meaningful and sustainable FDI to be attracted into Nigeria.
