Governments have an obligation to ensure the right of everyone to an adequate standard of living for himself and his family, including adequate food, clothing and housing, and to the continuous improvement of living conditions. They recognize the fundamental right of everyone to be free from hunger[2].

The main criteria for the right to food are :

• the availability of food;
• geographical proximity and
• the economic accessibility of
  food;
• the adequacy of food, which must be healthy, safe and meet the needs of people according to their age, physical and socio-economic conditions;
• the sustainability of the food system which allows the development of a network of territorial collaboration that integrates
  production, transformation, processing, production
  distribution and consumption of food products as well as the
  management of residual materials, in the goal of increasing health
  environmental, economic and
  the community’s social fabric. [3]
