Quick Summary

North Yorkshire farmer Tim Rooke is experiencing a significant decline in his potato harvest due to this summer's prolonged dry spell and extreme heat, which have reduced yields by about 4%. Farmer Richard Bramley near Selby anticipates a 20% to 25% drop in crop yield. Both farmers attribute these losses to climate change, noting that potatoes require at least 200ml of rain or other water for growth but received only around 35ml this year. DEFRA has acknowledged the issue with a £65 million package and is forming a new taskforce to address climate risks.

Story summary

This summer, British farmers faced significant challenges due to prolonged hot and dry weather, leading to smaller potato yields. Chief executive of growers' association GB Potatoes, Scott Walker, noted that shoppers should expect fewer large varieties on store shelves this year. North Yorkshire farmer Tim Rooke reported a loss of about two tonnes in every fifty tonnes harvested because the potatoes did not grow to the desired size due to early harvesting caused by crop stress from lack of water and extreme heat. The potato crops typically require 200ml of rain or irrigation, but received only around 35ml this year, with temperatures soaring above the optimal growth limit of 28°C. Rooke warned that future enthusiasm for growing potatoes may wane as climate change continues to affect crop yields, making it an expensive endeavor without proper government support. Farmer Richard Bramley near Selby echoed similar concerns and called for interest-free loans from the government to help farmers invest in necessary infrastructure or adaptation measures.
