Food security is defined as the state in which people at all times have physical, social, and economic access to sufficient and nutritious food that meets their dietary needs for a healthy and active life.
In an effort to increase global food security, DuPont, a global science company, commissioned the Economist Intelligence Unit to create an index aimed at addressing the underlying factors of food insecurity and pointing to areas for improvement and reforms.
The Global Food Security Index (GFSI), launched in June 2012, is based on a quantitative and qualitative scoring model that measures levels of food security across 105 countries by addressing the central issue of how consumers can easily access sufficient amounts of affordable, high-quality and safe food.
This WBCSD case study (3 pages) provides details on the GFSI methodology and its application in practice.
