Potatoes in Peril: Climate Change’s Impact

As the world continues to grapple with the consequences of climate change, the impact on global food production is becoming increasingly apparent. One crop that is feeling the effects is the humble potato, a staple food in many countries around the world. In this blog post, we’ll explore how climate change is affecting the production of potatoes and what it means for the future of this beloved vegetable.

The Impact of Rising Temperatures on Potato Production

Potatoes are a cool-season crop that thrives in mild climates. However, rising temperatures caused by climate change are making it more difficult to grow healthy potato plants. The warmer temperatures are causing potato plants to grow faster, which can lead to smaller tubers and lower yields. In addition, warm temperatures can cause the plants to wilt and become more susceptible to disease.

Droughts and Potatoes

In addition to rising temperatures, climate change is also causing more frequent and severe droughts in many parts of the world. This is particularly problematic for potato production, as potatoes require a consistent supply of water to grow properly. Without enough water, potato plants may not produce as many tubers or may produce smaller, misshapen tubers.

Extreme Weather Events and Potato Crops

Climate change is also increasing the frequency and severity of extreme weather events, such as hurricanes and floods. These events can have a devastating impact on potato crops, washing away entire fields or causing widespread crop damage. In addition, extreme weather can make it difficult for farmers to plant and harvest potatoes, leading to lower yields and higher costs.

The Role of Potato Diversity in Mitigating Climate Change

One way to mitigate the impact of climate change on potato production is to promote potato diversity. By planting different varieties of potatoes with different characteristics, farmers can increase their resilience to a changing climate. For example, some potato varieties are more tolerant of drought or disease, while others are better suited to warmer temperatures.

UK researchers are looking to varieties from the Andes mountains in South America (among others) to mine for traits such as heat , drought , pest and disease resistance.


Another way to promote potato diversity is to encourage the use of traditional potato varieties that may be better adapted to local growing conditions. These varieties may not be as well-known or widely available as commercial varieties, but they can be an important source of genetic diversity for future potato breeding programs.


Climate change is already having a significant impact on global food production, and potatoes are no exception. Rising temperatures, droughts, and extreme weather events are all affecting the production of this important crop. However, by promoting potato diversity and investing in research and development, we can help ensure that future generations have access to this versatile and nutritious vegetable.
