Impact Of Major Emergencies On Food Security Risks, Cuihong Yang, Kang Lin, Xiang Gao

Bulletin of Chinese Academy of Sciences (Chinese Version)

In recent years, the probability and frequency of international major emergencies are on the rise, which have threatened the global food security. The study decomposes the food supply chain into production section, consumption section, and circulation section; and then analyzes the risks of food security in each section when facing the major emergencies. In the production section, major emergencies restrict the inputs of labor and agricultural production materials, limiting food supply directly. In the consumption section, major emergencies usually increase the food price and decrease the resident income, and thus, decline the purchasing power of food and exacerbate the food …

Bulletin of Chinese Academy of Sciences (Chinese Version)

China enters into a new era with high demand for nutritional and healthy food, and hence needs to adjust the agricultural production system to balance cereal production and livestock farming. Between the years 2010-2019 the production of red meat and milk has fallen far behind the consumption demand, resulting in sourcing and import of large quantity of red meat and milk products from the international market. In comparison to the average consumption levels in Asia and global, China's consumption will continue to grow in the future, presenting a great challenge to the goals of 85% self-sufficiency rate for beef and …
