World Food Day (WFD) is celebrated annually on October 16th in honour of the foundation of the FAO in 1945. This year?s theme is ?Sustainable food systems for food security and nutrition?. FAO reports that 925 million people are under-nourished and 2 billion are affected by micronutrient malnutrition. Unsustainable development models are degrading the natural environment and threatening the ecosystems and the biodiversity that will be needed for future food and nutrition security. Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life. FAO defines four criteria that must be met simultaneously to meet food security objectives: food must be physically available, economically accessible, and usable, and these three conditions must be relatively stable over time.
