The Global Food Security Index consists of a set of indices from 113 countries.
[3] Much research is underway to increase the productivity of crops, and therefore cultivate a greater volume of food.
[3] But, unless that research extends to countries characterized by poor, high-density populations, Global Food Security Index scores are likely to decrease in the coming years.
[2] Some journals, such as Science, suggest that it is imported that play the biggest role in producing these index scores, as in developing countries, a much greater percentage of the working force is dedicated to agriculture, yet they remain the countries with the lowest Global Food Security Index Scores.
[2] This is further illustrated by the fact that the United States and Singapore consistently have the two highest Global Food Security Index scores, even though the portion of their respective economies dealing with agriculture is comparatively negligible.
