Description

The risk assessment of regional sustainable food security is one of the most important issues, and is closely related to regional sustainable development and maintaining social stability. This paper mainly focuses on the characteristics of sustainable food security problems in the major grain-producing areas in China. We establish an index system based on land resources and eco-environmental conditions and apply a dynamic assessment method based on status assessments and trend analysis models to overcome the shortcomings of the static evaluation method. Using fuzzy mathematics, the risks are categorized into four grades: negligible risk, low risk, medium risk and high risk. A case study was conducted in one of China’s major grain-producing areas: Dongting Lake area. The results predict that the status of the sustainable food security in the Dongting Lake area is unsatisfactory for the foreseeable future. Therefore, appropriate policies and measures should be put forward to improve it.

Risk Assessment for Sustainable Food Security in China According to Integrated Food Security—Taking Dongting Lake Area for Example

The risk assessment of regional sustainable food security is one of the most important issues, and is closely related to regional sustainable development and maintaining social stability.
