An empirical investigation of the effects of poverty and urbanization on environmental degradation: the case of sub-Saharan Africa

Abstract

This study empirically investigates the effects of poverty and urbanization on environmental degradation for a sample of 43 sub-Saharan African (SSA) economies from 1995 to 2018. The major contribution of the study lies in examining the existence of non-linear effects of poverty and urbanization on environmental degradation. We considered a set of institutional and demographic factors to explain the dynamics among poverty, urbanization, and environmental degradation. Findings suggest that an increase in the poverty gap significantly contributes towards intensifying environmental degradation in SSA countries. Results also show the existence of a non-linear relationship between poverty and environmental degradation. The findings purpose several crucial policy recommendations which necessitate the participation of different stakeholders such as government, institutions, researchers, non-profit organizations and citizens for the effective implementations of environment-friendly policies. A battery of robustness tests confirms the validity of the main findings of the study.
