The USDA Economic Research Service (ERS) defines food insecurity as a household characteristic. Food insecure households are those for which “consistent access to adequate food is limited by a lack of money and other resources at times during the year” (See more at: USDA-ERS).

Food losses refer to the decrease in edible food mass throughout the part of the supply chain that specifically leads to edible food for human consumption. Food losses take place at production, post-harvest and processing stages in the food supply chain. Food losses occurring at the end of the food chain (retail and final consumption) are rather called “food waste”, which relates to retailers’ and consumers’ behavior.

Food security exists “when all people at all times have access to sufficient, safe, nutritious food to maintain a healthy and active life.” According to the World Health Organization (WHO), the three pillars of food security are: availability, access and (safe) utilization. In addition you can learn about the four dimensions of food insecurity at the FAO website.

To be sustainable, any entrepreneurial activity must be economically viable, ecologically healthy and socially equitable. A universal definition of sustainability was given for the first time by the World Commission on Environment and Development (WCED) in the Brundtland report published under the auspices of the United Nations in 1987.
