Climate change is putting a crimp on the future viability of many of our favorite foods — and now a new study says that tea could face significant impacts from shifting seasonal patterns.
In a report published in the journal Climate,Tufts University researchers scoured through historical weather records as well asCamellia sinensistea production data from the years 1980 to 2011 using a unique "yield response model" to predict the "onset, duration, and retreat of the East Asian Monsoon." After crunching the numbers, the scientists discovered a "delayed monsoon retreat and increased daily precipitation during the monsoon period was negatively associated with tea yields."
The study found that just a 1 percent increase in the date of the "monsoon retreat" would lead to a reduction in yields between 0.48 percent and 0.535 percent. A1 percent increase inaverage daily rainfall would cut tea yields by "0.18 percent to 0.26 percent."

The researchers warned that adaptation plans needed to be put in place to assuage the severe effects of rising global temperatures.
"If monsoon periods continue to be longer and produce heavier daily rainfalls that could reduce tea yield and quality, then there needs to be changes in management techniques, such as possibly planting tea varietals that are more tolerant of increased precipitation or managing soil in ways to increase water holding capacity,"Rebecca Boehm, lead author of the study, said in a press release.
A report from Climate Central in 2015 found that "tea growing regions could decline in some parts of the world by up to 40-55 percent in the coming decades" due to the results of a changing climate.
Despite the dire outlook on tea forecasts, Boehm said her science team's goals were to help tea farmers better prepare for the worst.
“We hope that our approach will enable researchers to more accurately assess how monsoon and seasonal dynamics affect crop productivity," she concluded.
