Abstract: This paper analyzes the effects of climate change on the level of poverty and inequality in sub-Saharan Africa. We use a parametric and semi-parametric model of a triangular system and apply it to data from panels from twenty sub-Saharan African countries covering the period from 2000 to 2016. We use the ?generalized joint regression modeling? (GJRM) procedure to estimate the model. The results show that if climatic variability (rise in temperature and fall in rainfall) induces low agricultural yields, their effects on poverty and inequalities appear in the form of a nonlinear relationship. Climate shocks negatively and significantly affect only the yield of sorghum at the poverty line of $3.20, while their effects are positive and significant on the prices of cereals (millet, corn, sorghum). Given the impacts of climate change on well-being, African governments should integrate the climate dimension into poverty and inequality reduction programs and policies.
