Wed Dec 04 07:28:10 UTC 2024: ## Climate Change Threatens China’s Potato Production, Sparking Urgent Research
**Beijing, China – December 4, 2024** – A new study reveals a looming threat to China’s potato production, the world’s largest, due to climate change. Rising temperatures and extreme weather events are drastically reducing yields, jeopardizing global food security.
Research conducted by the International Potato Center (CIP) in Beijing shows that a 3-degree Celsius increase above average temperatures – a scenario projected by the UN for the end of the century – resulted in a more than 50% reduction in potato yields. The study, published in *Climate Smart Agriculture*, also found that while higher temperatures accelerated growth, the resulting tubers were significantly smaller. This finding highlights the vulnerability of China’s most common potato varieties to heat stress.
The impact is already being felt by farmers. In Inner Mongolia, heavy rains have caused disease outbreaks and hampered harvests. Farmers report facing significant challenges due to extreme weather. To combat these challenges, some companies are investing in aeroponic systems for growing potatoes, while others are developing heat-tolerant varieties.
CIP researchers are collaborating with the Chinese government on a three-year study to develop adaptation strategies. These include encouraging farmers to plant during spring instead of summer and exploring cultivation at higher altitudes. Scientists are also working to breed potato varieties that are more resilient to heat and disease, such as late blight, a devastating pathogen.
“Farmers have to start preparing for climate change,” warns CIP researcher Li Jieping. “If we don’t find a solution, they will make less money from lower yields and the price of potatoes may rise.” The findings underscore the urgent need for global action to mitigate climate change and develop climate-resilient agricultural practices to ensure future food security.
