Climate change poses significant challenges to U.S. apple production, with prime regions like Yakima, Kent, and Wayne facing increasing risks, as revealed by a Washington State University (WSU) study.
Researchers examined over four decades of climate data, focusing on factors like extreme heat, warm nights, and chill portions, which affect apple tree growth and fruit quality.
Yakima County, the largest apple producer with over 48,800 acres of orchards, has experienced concerning trends in five of six analyzed metrics. These include extreme heat days and reduced cold periods, both of which harm apple coloration and overall quality.
“We shouldn’t take the delicious apples we love to consume for granted,” said WSU climate scientist Deepti Singh. “Changing climate conditions over multiple parts of the growth cycle pose potentially compounding threats to the production and quality of apples.”
Growers are adapting with innovative techniques, such as netting and evaporative cooling, to combat extreme heat. In Washington state, research funded by a $6.75 million USDA grant is exploring ways to mitigate climate risks on apple and pear crops.
According to Lee Kalcsits, a WSU tree physiologist, apple trees’ perennial nature adds complexity to the challenge.
Seasonal changes can have long-term impacts on tree health and productivity. Efforts in Washington provide a case study for addressing climate risks across other regions.
