Climate change could significantly affect Europe’s dairy industry, with annual heat-related milk production losses projected to increase from approximately 4.5 million metric tonnes to 12.2 million metric tonnes by 2050 under a high-warming scenario. A new study by Rabobank warns that rising temperatures and changing rainfall patterns are reshaping Europe’s traditional dairy production environment, creating growing challenges for farmers, processors and the wider milk supply chain.
The research highlights how regions historically characterised by favourable grassland conditions and limited exposure to extreme heat could face increasing pressure on animal welfare, milk yields and production reliability. Although the changes are not expected to displace Europe’s major milk-producing regions, they could weaken their competitiveness as climate-related production constraints become more pronounced.
Southern and Central European Dairy Regions Face Greater Climate Risks
According to the study, the impact of rising temperatures will vary considerably across European dairy-producing regions, depending on local warming patterns and differences in herd composition.
Northern Italy, southern Germany, France and Spain are among the major dairy-producing areas expected to experience a marked increase in potential heat-related milk losses. These regions could face growing difficulties in maintaining consistent milk production as higher temperatures affect cattle comfort, feed intake and overall productivity.
The study estimates that annual heat-related milk losses across the European regions assessed could rise to 12.2 million metric tonnes around 2050, compared with approximately 4.5 million metric tonnes under current climatic conditions.
For dairy processors, the consequences could extend beyond reduced raw milk availability. Lower milk collection volumes could result in underutilisation of processing facilities, increasing operational costs and putting additional pressure on the competitiveness of affected dairy businesses.
The changing climatic conditions could therefore influence not only farm-level productivity but also the economics of milk procurement, processing and distribution.
Northern European Regions Retain Relative Production Advantages
While several major European dairy regions face increasing climate-related risks, Atlantic and northern European production areas are expected to retain a relative climatic advantage.
The study identifies southern Ireland as an example of a region likely to experience comparatively limited additional production losses. With annual milk production of approximately 6.2 million metric tonnes, southern Ireland represents the third-largest production base in the table assessed by the researchers.
The region is expected to experience an additional future milk production loss of only 0.3% of total output, highlighting the differences in climate exposure across Europe’s dairy-producing geography.
These regional variations could influence the relative competitiveness of dairy production areas over the coming decades, particularly as processors assess sourcing strategies and the long-term reliability of milk supplies.
Cooling Technologies and Farm Management Key to Reducing Heat Stress
Rabobank clarified that the projected figures should not be interpreted as a definitive forecast of future milk production. Instead, they illustrate potential outcomes under a warmer climate if herd size, productivity, breed composition and existing heat-management practices remain unchanged.
The study emphasises that adaptation measures could substantially limit the impact of rising temperatures on dairy production.
Cooling technologies, including artificial shade, sprinkler systems and improved ventilation, are identified as some of the most effective approaches to reducing heat stress in dairy cattle.
However, implementing these technologies requires significant capital investment. The study estimates that equipment upgrades can start at an average cost of approximately €30,000 per farm, with the payback period depending on individual farm output and operating conditions.
In addition to infrastructure improvements, farmers can strengthen resilience through adjustments to feeding strategies, herd management, breed selection and genetic programmes that prioritise heat tolerance.
Improved nutrition and management practices could help maintain animal comfort and productivity during periods of elevated temperatures.
Dairy Processors Encouraged to Support Climate Adaptation
The research also highlights the responsibility of dairy processors in supporting climate adaptation across their milk supply chains.
As heat stress, drought and extreme weather events can influence milk volumes and supply reliability, processors have a direct commercial interest in helping farmers improve farm-level resilience.
Rabobank recommends that processors support adaptation through technical assistance, knowledge-sharing initiatives and financial incentives. Existing animal-welfare and sustainability programmes could provide established channels for introducing heat-management measures across supplier networks.
Investment in farm infrastructure and improved management practices could help maintain consistent milk procurement while reducing the risk of supply disruptions.
The study further suggests that processors may need to introduce greater flexibility into sourcing arrangements, infrastructure planning and operational strategies to respond to changing production conditions.
Climate Resilience Emerging as a Competitive Priority for European Dairy
The findings underline the growing importance of climate adaptation in Europe’s dairy industry. While established milk-producing regions are expected to remain central to European production, differences in climate exposure could gradually influence their relative productivity and competitiveness.
For dairy farmers, investment in cooling systems, animal nutrition, suitable genetics and improved herd management will become increasingly important. For processors, supporting suppliers through technical and financial assistance could help protect raw milk availability and processing efficiency.
As the industry approaches 2050, the ability to adapt production systems to warmer conditions will be critical to maintaining animal welfare, farm profitability and the long-term resilience of Europe’s dairy supply chain.
