Item The economic growth-environmental sustainability nexus in developing countries: Some evidence from Sub Sahara Africa(University of Ghana, 2015-04-17) Aboagye, S.Ensuring environmental sustainability amidst the quest to stimulate growth in SSA remains an issue of great concern and therefore considered extremely important in contemporary growth agenda in many developing countries. Notwithstanding these, the evidence for SSA remains very sparse, as literature has not adequately examined the effects of SSA's economic growth process on environment sustainability in the region. Using a panel dataset from 1980-2010 covering 28 SSA countries and employing environmental pollution, degradation and sustainability indices, this study examines the environmental impact of economic growth within the standard Environmental Kuznet Curve (EKC) framework. Estimation by the system Generalized Method of Moment confirmed the existence of the Environmental Kuznet Curve (EKC) hypothesis for environmental sustainability and degradation measured respectively by Adjusted Net Savings and energy consumption but was not confirmed for environmental pollution as the findings were not supported by data on C02 e missions. Additionally, greater openness to trade was associated with a fall in both pollution and environment sustainability but for urbanization the contrary was found to exist. Furthermore, industrialization was also found to unambiguously harm the environment while the converse was established for FDI. These findings have stern theoretical and policy implications for the economic growth-environmental sustainability nexus in SSA and further cast doubts on validity of the EKC for C02 especially for SSA. Following this evidence we discuss some policy optionsItem Energy consumption intensity in Sub-Saharan Africa: Evidence and policies(University of Ghana, 2015-04-17) Aboagye, S.; Nketiah-Amponsah, E.The aftermath of the 1970 oil price shock coupled with rapid urbanization, rising population, industrialization and increased environmental degradation in Sub Saharan Africa (SSA), have necessitated a shift of emphasis from energy consumption to a thorough investigation into energy consumption intensity. This notwithstanding, the evidence remains sparse for SSA as literature has not adequately examined the effects of SSA's economic growth process on energy intensity in the region and this is what the study addresses using a panel dataset from 1980-2010 covering 36 SSA countries. A system Generalized Method of Moment (GMM) estimation confirmed the existence of a U-shaped economic growth-energy consumption intensity nexus in SSA. Additionally, both urbanization and industrialization are found to increase energy consumption intensity while the contrary existed for FDI and trade. Inflation was not found to include the drivers of energy consumption intensity. Against these we discuss some policy options.
