Grain security or food security: on China’s food security issues

2014-08-28

By Xiao Junyan 

Date: 2004/12/14

Abstract:  

The notion of "food security" rather than "grain security" is the one accepted internationally; the former is the better one in revealing the food and nutrition condition of the people. The concept of "food security" refers to security of basic food consumption rather than satisfaction at a higher level; therefore the bottom line of food security does not necessarily require 400 kg per capita food grain. At present time, the food security condition in China is stable; conceptually "food security" should replace "grain security"; in policy making, we must avoid the tendency of "generalized grain security" and carefully study and make appropriate policies for a stable food security system.?
