CLIMATE CHANGE AND FOOD SECURITY: EVIDENCE, IMPLICATIONS, AND CONVERGENCE FOR AFRICAN COUNTRIES
Keywords:Panel Data Model, Agriculture, Africa, Climate, African Countries
The strong and complex multifaceted climate change impacts in African countries are evident from long-prevailing hunger and food insecurity, hence widespread undernourishment. The present study is designed to investigate the continuously evolving climate change impacts affecting the food security status of agrarian food-insecure African countries to envisage factual research-based policy implications for development practitioners and stakeholders. For this purpose, the data of key variables have been taken from 1990-2019, the Driscoll Kraay second-generation regression analysis has been employed for overall analysis. For in-depth analysis, the error correction method (ECM) with Pooled Mean Group Specification has been used to capture climate change's long-run and short-run impacts on food security coupled with other key control variables such as population density, democratic institutions, arable land and cereal production. The study found that a warmer climate and intensive rainfall adversely affect food security or worsen the condition of the prevalence of undernutrition. The long-run results of Discroll Kraay's methodology clarify that temperature is statistically significant and adversely associated with the prevalence of undernourishment. At the same time, temperature square, rainfall, and rainfall square are statistically significant and positively related to undernourishment prevalence. As far as the concern about the short run using Driscoll Kraay coefficient of error correction term is found to be negative and statistically significant, showing that there is convergence towards its long-run equilibrium. The estimated model also suggests that the adaptation of climate-smart technologies is helpful in the escalation of food security.
