Food security means that all people at all
times have both physical and economic access
to basic food. This requires not just
enough food to go round. It requires that
people have ready access to food-that
they have an "entitlement" to food, by
growing it for themselves, by buying it or by
taking advantage of a public food distribution
system. The availability of food is thus
a necessary condition of security-but not
a sufficient one. People can still starve even
when enough food is available-as has happened
during many famines
