How Climate Change Impacts Potato Production: A Look Back and Forward
This article examines the impact of climate change on potato production from 2008 to 2022, highlighting the effects of rising CO₂ levels, temperature changes, and erratic rainfall patterns. It highlights the need for adaptive strategies, such as precision irrigation and pest-resistant varieties, to increase resilience and ensure sustainable production.

Introduction
Climate change, driven by increasing levels of greenhouse gases, has significant implications for agriculture worldwide. For potato production, understanding these impacts is critical because potatoes are a staple food crop. This article examines the impacts of climate change on potato production from 2008 to 2022, drawing on findings from two key studies and considering future implications.
Climate Change Impacts from 2008 to 2022
2008 Study: “Climate change and its impact on the potato supply chain”.
In 2008, a study by Haverkort and Verhagen highlighted the impact of rising carbon dioxide (CO2) levels, temperature changes and changing rainfall patterns on potato production. The study found that CO2 levels rose from 290 parts per million (ppm) during the Industrial Revolution to 380 ppm in 2008. This increase in greenhouse gases contributed to significant climate changes.
In southern Europe, reduced water availability and shorter winter seasons negatively affected potato yields. Northern Europe experienced a decrease in frost days, an extended growing season and increased winter precipitation. However, erratic summer rainfall and higher temperatures posed challenges. Warmer temperatures promoted larger tubers with higher dry matter concentration, but also increased pest and disease pressure, particularly late blight.
Economically, these climatic changes required investments in irrigation, new varieties adapted to extreme weather conditions, and improved storage facilities. The study highlighted the need for the potato industry to adapt by shifting production further north and developing more resilient farming practices.
2022 Study: “Multi-Level Impacts of Climate Change and Supply Disruption Events on a Potato Supply Chain: An Agent-Based Modeling Approach”
In 2022, researchers used agent-based modeling (ABM) to simulate the impacts of climate change and supply chain disruptions on potato production. This advanced approach allowed for a detailed analysis of how various factors, including pest and disease outbreaks, affect supply chain resilience.
The study highlighted increased pest and disease pressures similar to those identified in the 2008 study but with a more sophisticated understanding of their impact. The ABM approach provided insights into supply chain vulnerabilities and resilience strategies. Advanced adaptation measures, such as precision irrigation techniques and pest-resistant potato varieties, were recommended to mitigate the impacts of climate change.
Comparative Analysis
The methodologies used in the 2008 and 2022 studies were significantly different. The 2008 study relied on historical data trends and crop modeling to predict outcomes, while the 2022 study used ABM to create dynamic simulations of the supply chain under different climate scenarios.
Both studies found increased temperatures and CO2 levels, but the latter provided a more nuanced understanding of their impact on pest and disease pressure. Technological advances in agricultural practices and supply chain management between these years also played a critical role in increasing resilience to climate risks.
Visualize change
Key visuals from these studies include temperature trends, pest and disease cycles, and yield projections. The 2008 study illustrated how warmer temperatures led to larger, but potentially lower quality tubers due to increased pest pressure. The 2022 study used ABM to visualize how supply chain disruptions could be mitigated through adaptive strategies.
Significant data shifts included the increasing frequency of extreme weather events and their impact on water availability and the spread of disease. Consistent trends, such as the lengthening of the growing season in northern Europe, remained evident throughout both periods.
Summary and outlook
Comparing the two periods, it is clear that modern approaches emphasize resilience and adaptation strategies. The 2022 study highlights the importance of technological advances, such as ABM and precision irrigation, in understanding and managing climate risks more effectively.
Looking ahead, a focus on breeding pest-resistant varieties, improving water use efficiency, and increasing storage capacity will be critical. Technological advances will continue to play a key role in mitigating climate impacts and ensuring sustainable potato production.
Conclusion
Understanding the impacts of climate change on potato production is critical to developing effective adaptation strategies. As the climate continues to change, the potato industry must remain proactive in adopting innovative practices to ensure food security. The journey from 2008 to 2022 highlights the importance of resilience and technological advancement to meet the ongoing climate challenges.
