Extreme heat and drought are impacting German crop yields, prompting farmers to adopt new breeding techniques, irrigation strategies, and crop diversification to adapt to a changing climate.

A late June heat wave in Germany has caused significant stress for local agriculture, particularly affecting corn during its critical flowering stage. Horst Gömann of the North Rhine-Westphalia Chamber of Agriculture noted that extreme heat has led to some corn plants failing to form cobs, effectively resulting in total crop failure for those plants. The weather has also impacted wheat and barley yields, forcing the industry to accelerate its adaptation strategies.

Economic Impact on European Grain

The June heat wave, which saw temperatures exceed 40 degrees Celsius, caused widespread damage across Europe. According to Coceral, an association of European grain traders, the value of the European grain harvest dropped by more than €2 billion. The organization lowered its production expectations for the European Union and the United Kingdom by nearly 9 million metric tons, a 3% decline, with corn accounting for approximately half of this adjustment.

Adaptation and Technical Solutions

Farmers are increasingly relying on risk diversification by planting multiple grain varieties with varying maturity rates. To combat heat and frost, growers are utilizing tools such as frost-protection sprinklers, hail protection nets, and experimental semi-transparent photovoltaic films. While irrigation is effective for high-value crops like fruit and vegetables, experts note it is often not economically viable for grains or corn due to high costs.

Breeding and Future Resilience

Agricultural research is focusing on developing more resilient crop varieties, including wheat strains with deeper roots and shorter stalks. Scientists are also testing crops typically grown in warmer climates, such as soybeans and millet, in German soil. Experts emphasize that while agriculture has always adapted to environmental changes, the current pace of climate change requires a much faster response than in previous generations.
