This paper is a contribution to the empirics of climate change and its effect on sustainable economic growth in Sub-Saharan Africa. Using data on two climate variables, temperature and precipitation, and employing panel cointegration techniques, we estimate the short-and long-run effects of climate change on growth. We establish that an increase in temperature significantly reduces economic performance in Sub-Saharan Africa. Furthermore, we show that the relationship between real gross domestic product per capita on one hand, and the climate factors on the other, is intrinsically non-linear.

Environmental concerns in today's world cannot be overemphasised. These concerns have interested policymakers and researchers to delve into the causes in order to help mitigate environmental deterioration and support policies and institutions for environmental sustainability. This study, therefore, investigates the association between foreign direct investment (FDI) and environmental quality, taking into account policies and institutions for environmental sustainability across 23 Sub-Sahara Africa (SSA) countries. Employing the generalised method of moment (system-GMM) for the analysis, the results revealed, among others things, that FDI improves environmental quality in the long run, whereas in the short run, FDI diminishes environmental quality when interacted with policies and institutions for environmental sustainability. Furthermore, policies and institutions for environmental sustainability and domestic investment improve environmental quality in SSA in both the long and short run. The study, thus, concludes that policies and institutions for environmental sustainability in SSA are important as they improve environmental quality as well as complement FDI to improve environmental quality in the long run. The study further establishes that domestic investment is important to improve environmental quality in SSA. The study recommends policies for improving environmental quality to policymakers and stakeholders in SSA.

The article investigates the extent to which the health of the population affects the economic performance using panel data for 30 Sub-Saharan African countries for the period 1970-2010. Using a theoretical model based on an augmented Solow growth model, the authors estimate the relationship between population health capital and economic growth in Sub-Saharan Africa using panel cointegration econometric strategy. They find that the health status of the population has not significantly driven economic performance. Accounting for the effect of HIV=AIDS, however, resulted in a significant negative effect of population health on economic growth. Furthermore, the obverse seems rather plausibly the case, as economic growth significantly increases life expectancy in the region.
