In 2015, FAO estimated that approximately 795 million people are undernourished in the world. The United Nations has regularly qualified this situation as “a violation of human dignity”. In this context, the international cooperation legitimately became a privileged means to fight against malnutrition. However, the access to food is at the crossroads of numerous problems. Some States are eager to assert their self-sufficiency while others meet difficulties managing their surpluses. Health or nutritional quality issues join concerns about the accelerated loss of genetic diversity. Responding to these various concerns, food has been the subject of many international rules. Some promote the liberalization of their production and trade, sometimes to the detriment of a consideration of the level of development of countries, of the biological diversity or the quality of food. Some take account of these issues but their coordination seems difficult with the rules of economic liberalization. Nevertheless, States set up the access to food as a global goal and the coherence of international law seems essential for its achievement. The present study aims to determine to what extent international law, characterized by the fragmentation of its rules, contributes to improving the conditions of access to adequate food at the world level.
