Defined at the 1996 World Food Summit, food security:
“… exists when all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life”.
At individual and household level, food insecurity can affect low-income people in rich and poor countries alike. In the UK, policy-makers view food security as a strategic issue of national security, dependent on the logistical and political resilience of global trade relations. At a global level, how we can feed a growing population that demands more resource-intensive diets, while tackling climate change and environmental degradation, are key questions of food security.
