How does climate change impact food security in Central Asia?
A recent paper "Impact of climate change on food security in the Central Asian countries", published in Science China Earth Sciences, points out that while the overall level of food security has increased over the past 30 years, five countries in Central Asia now face a future crisis due to global warming. 
Recent years, the international community has shown extensive concern regarding the influence of climate change on food security. Central Asia has a fragile ecological environment and underdeveloped agriculture, and its food security is more sensitive to climate change. 
What is the current situation of food security in Central Asia under the influence of climate change? How will the future develop? This not only affects the region's development and stability but also poses challenges to building a China-Central Asia community.
To assess the current situation and predict future developments, a joint group from the Institute of Earth Environment, Chinese Academy of Sciences(CAS), Northwest University, National Academy of Sciences of the Republic of Kyrgyzstan, and other units evaluated food security across four dimensions: availability, accessibility, utilization, and stability using Cobb-Douglas-Climate (C-D-C) model, and meteorological, agricultural, economic data spanning from 1990 to 2019 for five Central Asian countries. Furthermore, they conducted an in-depth analysis of how climate change and extreme weather events impact food security within these countries while predicting their future trends under different climate scenarios.
They reveals that climate change has a significant impact on food security in Central Asian countries. Both average annual temperature and precipitation have an inverted U-shaped relationship with food security. Additionally, extreme high and low temperatures exert substantial negative effects on food security. Considering the anticipated global warming, it is highly likely that temperatures and precipitation will continue to rise in these Central Asian countries. Consequently, climate change will have long-term adverse implications for the region's future food security.
Dr. SU emphasizes the necessity for proactive measures by Central Asian countries to adapt to climate change and reduce greenhouse gas emissions in order to safeguard future food security of the region. Furthermore, she suggests taking the Belt and Road Initiative as an opportunity to enhance regional food and agriculture cooperation.
“This study will raise social awareness of climate change, provide scientific reference for building a food security system in Central Asia, and promote regional cooperation”, said Dr. TAN.
