Evaluation on Sustainable Food Security in Henan against the Background of Low-Carbon Economy

New requirements for sustainable food security are set against the background of Low-Carbon Economy (LCE). LCE Influences on sustainable food security include “Minimization” principle and “Recycling” principle. The present situation of sustainable food security in Henan Province is analyzed quantitatively. Preliminary conclusion is that, energy consumption in grain production and proportion of agricultural population in Henan Province is relatively large, the level of deep processing of agricultural products is too limited. On this basis, suggestions on sustainable food safety are given, such as the development of water-saving agriculture, reduction of energy consumption in agriculture and so on.
