Food safety issues are best decided in terms of efficient markets. Dependence on alternative sources exists, but in the case of underproduction by natural disasters (drought, flood, crop failure), even those countries that have a policy of food self-sufficiency are forced to rely on imports. The participants of the economic debate on the issue of the relationship of food self-sufficiency and food security are divided into two sides: the first believe that self-sufficiency is the only guarantee of food security in the long term plan; others rely on the free trade system capable of ensuring long-term food security for all.
