In 1974, FAO defines food security as food security, which fundamentally refers to a basic human right to life, that is, "anyone should ensure that he gets enough food for his future survival and health", and it emphasizes that getting enough food is a basic human right to life.
1983, FAO revised this definition and put forward that the goal of food security is to "ensure that all people can buy and afford the basic food they need at any time". Food security is an important foundation of political security and economic security, and it is also the most important livelihood issue.
Grain is not only an important strategic material related to the national economy and people's livelihood and national economic security, but also the most basic means of livelihood for the people. Food security is closely related to social harmony, political stability and sustained economic development. It is the responsibility of the government and an important part of the food security system to improve the food emergency reserve system, ensure the food supply in the market and minimize the food security risks in the emergency period.
Influencing factors of food security:
1, population factor:
Among all the factors affecting food security, the population factor should be the most direct and important. However, it should be pointed out that this influence is not only manifested in the pressure of population increase on food supply, but also in the changes of production factors and structure.
2, climate ecology:
There is a high causal relationship between food production and climate ecology, especially under the condition that the ecological environment is destroyed to a certain extent and extreme weather occurs repeatedly, climate variation has become a key factor directly affecting food security. In this regard, FAO's research report pointed out that agricultural production in the next 20 to 50 years will be seriously affected by climate change, which will further seriously affect the global ultra-long-term food security.
3. Unexpected factors:
In addition to the normal factors such as population and climate that directly affect food production, accidental factors will also have an impact on food security. In particular, the outbreak and spread of the global financial crisis have had a significant negative impact on the input, market transactions and even the future direction of world grain production, and this impact may be long-term and in-depth.
