In the search to guarantee Food Security during the 70s, it was believed that it would be enough to increase the productivity of agro-industry in the world. However, the work of Amartya Sen was fundamental in clarifying the concept of Food Security and showing that the death of thousands of people during the famines in Bengal, Ethiopia and Bangladesh, was due to a lack of access to food, and not because of their insufficiency. These testimonies, together with the dimensions of Food Security, shaped the concept, stressing with it the importance of guaranteeing food regardless of the political instability of the countries or natural disasters that may occur.
