How Climate Change Is Set To Squeeze the Processed Tomato Industry
June 16, 2022 Climate change is on track to interfere with tomato production. According to a study published in Nature Food, rising temperatures are projected to lower yields around the world for processing tomatoes. By 2050, the global supply of processing tomatoes is expected to decrease by 6% compared to the study’s baseline of 1990-2009, with Italy’s crop being among the hardest hit.
“The processing tomatoes are grown in the open fields, which means that we cannot control the environment in which they grow. This makes the production vulnerable to climate change,” says lead author Davide Cammarano, a Professor at Aarhus University.
Researchers from the University of Texas at Austin, Purdue University, the University of Salerno, the University of Florida, and NASA Goddard Institute for Space Studies also collaborated on the study.
Study co-author Dev Niyogi, a professor at the UT Jackson School of Geosciences and Cockrell School of Engineering, said that while the climate’s impact on the food supply is widely researched, most of the focus has been on staples such as wheat and rice. This study is among the first to take a global look at climate change’s impact on tomatoes.
“We know very little about how climate change will affect specialty crops, like the processing tomato, which has an incredible global food footprint, along with being an important source of nutrients and an ingredient in cuisines around the world,” Niyogi says. “This study is one of the first such global studies and this makes it unique.”
The researchers used five different climate models to inform three different scenarios projecting how rising temperatures will influence tomato yield, focusing in the world’s top three tomato-growing countries: the U.S. (California in particular), Italy, and China. Together, these countries produce about 65% of the world’s processing tomatoes.
