Urban and Peri-urban Agriculture, Household Food Security and Nutrition

The definition of food security has evolved to emphasise access to food, rather than mere availability of food. It also explicitly incorporates the need for a healthy diet, complete with necessary vitamins and proteins, rather than simply sufficient calories. Therefore, adequate national and community-level food supplies must be available year-round; households must have both physical and economic access to a sufficient quantity, quality and variety of foods; and primary household providers and care-givers must have the time, knowledge and motivation to ensure that the nutritional needs of all household members are met.
