There is a specific time significance behind every type of farming,and the major challenges and opportunities at development stage are all annotated. Under the atmosphere of global climate change,how to coordinate the relationship between greenhouse gas emission and agricultural productivity,so as to realize climate change mitigation,ensure food security and increase farmers income is a theoretical and technological difficult problem facing entire world in present century. Under the initiation of Food and Agriculture Organization of the United Nations,climate-smart agriculture is becoming a new method for global agricultural development coping with climate change.
