Influence ofClimate andNon-Climatic Factors onGlobal Food SecurityIndex: A Cross-Sectional Country-Wise Analysis


Ajay Kumar Singh

The present study estimatesthe influence of climatic and non-climatic factors on global food security (GFSI) for 103 across countries. It also identifiesthat which group of countries is highly vulnerable in food insecurity due to climate changeand variability in socio-economic variables. For this, global food security index (GFSI) which is createdby Economist Intelligence Unit (EIU) considers as a dependent variable, that is regressed with climatic factors (i.e., annual mean temperature and annual precipitation) and non-climatic variables (i.e.cereal yield, per capita land under cereal production, population growth rate, consumer price inflationand forest area)using linear regression model. Estimates indicates that climatic factors (i.e., mean temperature and precipitation) show a negative and statistically significant influence on GFSI. Furthermore, empirical results based on ordinary least square(OLS) model shows that GFSI may be decreasedby 1.70% with 1% increase in mean temperature. GFSI has also negatively influenced with rising population growth rate and inflation. Lower and low-incomegroup countries are most vulnerable as compared to high income group countries. The major findings of this study suggested that price inflation and high population growth rate are most responsible variables for food insecurity in most developing countrieslike India
