| description | Food security in developing regions such as Sub-Saharan Africa is a top priority in global development discourse, as evidenced in Sustainable Development Goal 2. Yet, high climate vulnerability poses serious challenges to food security in Africa even though the literature is inconclusive. Using data from 40 selected Sub-Saharan African (SSA) countries from 2000 to 2021, this paper investigates the extent to which climate variability affects food security in SSA. Principal Component Analysis (PCA) is used to construct a food security index derived from its four dimensions (availability, accessibility, utilization, and stability). The proxies for climate variability included precipitation, temperature, and CO2 emissions. The Panel Corrected Standard Error (PCSE) technique, which takes into account the cross-sectional dependency, serial correlation, and heteroscedasticity, was employed. The empirical results show that precipitation and CO2 emissions influence food security positively, while the association between temperature and food security is negative. Indeed, achieving food security in Africa requires robust and feasible policies capable of mitigating climate vulnerability and impacts on the continent. |
