Food security extends beyond a population’s immediate nutritional intake. It is not only an essential pillar of the nation concept, but has far-reaching implications that extend beyond national borders in today’s globalized trading of agricultural commodities. The Global Hunger Index (GHI), an established metric for measuring food insecurity in developing countries, can be used to measure the overall impact of agricultural economic policies. Multiple regression and ANOVA tests were implemented to examine the significance a range of predictors had on determining GHI in India, Nigeria, and Brazil. Each country has a major impact on food security for their region, along with global economic policies. The predictors encompass a variety of factors including basic, political, economic, and infrastructural needs. The data for the research was acquired from The Food Agricultural Organization Food Security Report and the International Food Policy Research Institute for 1995-2011. The study finds that the GHI in India and Nigeria was significantly affected by gross domestic product per capita (GDPC) and water access, while only water was significant in determining Brazil’s GHI. With this research as a template, policy makers can better tailor aide programs to optimize the global decrease of the GHI and improve global food security.
