Question

Explain the study of spato - temporal aspects of food security by physical map.

Answer 1

Since 1970s, the definition of 'food security' has gone through many changes. In 1996, the World Food Summit defined food security as a condition where people are able to physically and economically access safe, sufficient and nutritious food which would meet their dietary needs and preferences of food for an active and healthy life.

The three components of identifying the necessary conditions for sustainable food security are food availability index, food accessibility index and food utilization index. These are the spatio - temporal aspects of food security.
