Recently, Tan Liangcheng, a researcher from the “Extreme Climate Events and Impacts” team of the Institute of Earth Environment, Chinese Academy of Sciences, together with Professor Su Fang of Northwest University and Dr. Rustam Orozbaev of the Institute of Geology of the Kyrgyz Academy of Sciences, based on the meteorological, agricultural and economic data of the five Central Asian countries from 1990 to 2019, used the C-D-C model to comprehensively study and judge the food security status of the five Central Asian countries from the aspects of food availability, availability, availability and stability. This paper deeply analyzes the impact and mechanism of climate change and extreme weather events on the food security of the five countries, and predicts the development trend of food security in the five countries under different climate scenarios in the future.
In recent years, with the intensification of global warming, the impact of climate change on food security has aroused widespread concern in the international community. The five Central Asian countries are deeply landlocked, with fragile ecological environments and backward agricultural development, making the region’s food security more sensitive to climate change. What is the current state of food security in the five Central Asian countries? What are the impacts of climate change and extreme weather events on food security? What does the future hold? This will not only affect the development and stability of Central Asian countries themselves, but also pose challenges to the construction of a China-Central Asia community with a shared future.
The study shows that the overall food security level of the five Central Asian countries has been on an upward trend over the past 30 years, but they are facing a crisis. Climate change has a significant impact on the food security of the five Central Asian countries, and there is an inverted U-shaped relationship between the average annual temperature and precipitation and food security, and extreme high temperature and extreme low temperature have a significant negative impact on food security. Under the expectation of global warming, the temperature and precipitation in the five Central Asian countries are likely to continue to rise, and the future food security of the region will be negatively affected by climate change for a long time.

The study suggests that Central Asian countries should improve their awareness of climate risks and actively take various measures to adapt to climate change and reduce greenhouse gas emissions. The study also proposes the development path of food security in the five Central Asian countries from the perspective of human-land system, and the cooperation mechanism of food security in the five Central Asian countries under the Belt and Road Initiative.
