An Empirical Analysis of the Linkages among Food Security, Agflation, and Climate Change

This paper investigates the relationship of agflation and climate change on global food security. Using the annual data from 1990 to 2011, this paper utilizes the linear model, vector error correction model (VECM), and Granger causality as it establishes the relationship between food security (independent variable) and the dependent variables of climate change and agflation. The main findings suggest that the impacts of climate change and agflation on food security are not significant in the short run. Moreover, food security and climate change have a negative relationship in the long run. Finally, using Granger causality, food security was attributed to both agflation and climate change. Results imply that food policy makers must consider the main factors affecting food security, especially environmental changes. KCI Citation Count: 3
