Food Security and Food Systems

What is food 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”  – World Food Summit, 1996

But what does that mean? In the video, Prof. Dr. Andy Nelson from the International Institute for Geo-Information Science and Earth Observation, University of Twente (ITC/UTwente), gives an overview of food security and food systems.
