Food security continues to be a vital subject for every country, while the main mean of supply remains agriculture. In order to evaluate the situation and to discover the tendencies, we track the main production and distribution parameters; arable land, productivity, population and food consumption from 1961 to 2013, and we explore the minimum arable land per person, a way of estimating the necessary area of productive land according to consumption levels, while also taking note of relevant dietary shifts regarding the sources of calories and proteins. Our results show a trend of significant decrease of arable land per person, but also a similar decrease of minimum arable land per person. At the dietary level, we also found increases in consumption, along with a shift towards animal based energy in developing countries, while some developed countries plateaued. In line with the field’s literature, our results describe an increased consumption based on ecologically unsustainable large yield increases.
