Is there a trade-off between ICTs and ecological systems in Africa? Evidence from heterogeneous panel methods robust to cross-sectional dependence.

Abstract

Among the UN's 17 Sustainable Development Goals (SDGs), increasing infrastructure resilience (SDG9) and combating climate change and its impacts (SDG13) have been vital goals. Growing evidence supports the presence of a trade-off between expanding information and communication technologies (ICT) infrastructure and maintaining the quality of the environment. Based on an ICT index and the ecological footprint, the present study reinvestigated the influence of ICT on environmental quality for a sample of African countries, where ICT services have substantially increased over the past decades. The study employed cross-sectionally augmented autoregressive distributed lag (CS-ARDL) and common correlated effects estimator (CCEMG) techniques on data representing 47 African economies between 1990 and 2017. The results of both methods were consistent and indicated an inverted U-shaped relationship between ICT infrastructure and environmental quality in the long and short run. The findings suggested that the expansion of ICT infrastructure could simultaneously enable African nations to achieve SDG13 and SDG9.
