Closing the global ozone yield gap: quantification, co-benefits and multi-stress tolerance

This research paper quantifies the global impact of tropospheric ozone on crop yields, estimating a total annual loss of 227 Tg. It identifies the highest losses in the Americas, China, India, Bangladesh, and Indonesia, noting that these areas often face concurrent stresses from heat, pests, and disease. The authors recommend integrating ozone tolerance into crop breeding and management to improve food security.

• Based on data from 2010–2012, tropospheric ozone reduces annual global yields by 12.4% for soybean, 7.1% for wheat, 6.1% for maize, and 4.4% for rice, resulting in a total loss of 227 Tg of yield. The sensitivity to ozone follows the order of soybean > wheat > maize > rice, with the most pronounced genotypic variation found in rice and soybean.
• The highest ozone-induced production losses occur in specific regions: North and South America for soybean; India and China for wheat; China and the United States for maize; and China, Indonesia, Bangladesh, and parts of India for rice. These areas frequently overlap with regions at risk of heat stress, pests, diseases, and, to a lesser degree, nutrient stress and aridity.
• To address the ozone yield gap, the authors suggest incorporating ozone effects into crop breeding programmes to create a crop ideotype tolerant of multiple stresses, as well as implementing altered crop management approaches for short-term impact reduction.
