According to the definition that can be found in the Encyclopaedia Britannica[1], the term food means any substance that is consumed to ensure the nutritional needs of the organism. Food is usually of plant or animal origin and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins or minerals. Food is taken into the body and absorbed in the cells of the body to provide energy, sustain life or encourage growth. Based on this definition, it is quite clear that in the history of human civilization, wars were fought to conquer new areas, and thus meet the nutritional needs of certain peoples. When we talk about food, we inevitably talk about food chains. In free nature, every food chain starts with herbivores, then carnivores and finally omnivores, including man. With the domestication of wild animals and the cultivation of the first economically important plant species, the period of agriculture begins, which lasts until today. With the introduction of agriculture, man changed his way of life and the first civilizations emerged, and with the emergence of the first civilizations the first cities, the first letters and the Anthropocene period began, which lasts to this day[2] and will stop when natural resources for food production are exhausted or no longer available[3]. The development of agriculture enabled the development of other activities, because with the development of civilization, the first agri-food chains were formed, which enabled the division of labor. Agrifood chains connect all parts of food systems that have developed more or less in proportion to the increase in human population, and as one after another, various innovations in agricultural production and logistics were implemented, the world trade also grew. However, today’s agricultural production is very different from agricultural production only thirty years ago. Two moments were crucial for that, one of global and economical nature and the other in the form of a natural phenomenon. Namely, in May 1986, at the G7 economic summit in Tokyo, a major problem in world food trade was noticed, and four months later the Uruguay Round of negotiations on GATT (General Agreement on Tariffs and Trade) began. General Agreement on Tariffs and Trade), which was to devise trade and agricultural policy rules, bringing world agriculture under the effective rules of the GATT[4], with all the positive but unfortunately also negative consequences for food security and adequacy in many countries. Another moment that has disrupted the accounts of GATT creators is global climate change, which inevitably affects almost all socio-economic aspects related to food systems, from agricultural and livestock production to global trade, demography and human behavior, which all together affect food security and food self-sufficiency[5]. However, a third phenomenon has recently emerged that highlights the vulnerability of agri-food chains and food systems at the state level, the COVID-19 pandemic, 12 which combined with global climate change is a serious threat to food security and food self-sufficiency in many countries of the world, and especially in the poorest ones[6].
