Meta-analysis was conducted to quantitatively assess the effects of rising ozone concentrations ([O-3]) on yield and yield components of major food crops: potato, barley, wheat, rice, bean and soybean in 406 experimental observations. Yield loss of the crops under current and future [O-3] was expressed relative to the yield under base [O-3] (<= 26 ppb). With potato, current [O-3] (31-50 ppb) reduced the yield by 5.3%, and it reduced the yield of barley, wheat and rice by 8.9%. 9.7% and 17.5%, respectively. In bean and soybean, the yield losses were 19.0% and 7.7%, respectively. Compared with yield loss at current [O-3], future [O-3] (51-75 ppb) drove a further 10% loss in yield of soybean, wheat and rice, and 20% loss in bean. Mass of individual grain, seed, or tuber was often the major cause of the yield loss at current and future [O-3], whereas other yield components also contributed to the yield loss in some cases. No significant difference was found between the responses in crops grown in pots and those in the ground for any yield parameters. The ameliorating effect of elevated [CO2] was significant in the yields of wheat and potato. and the individual grain weight in wheat exposed to future [O-3]. These findings confirm the rising [O-3] as a threat to food security for the growing global population in this century. (C) 2008 Elsevier Ltd. All rights reserved.

Evidence of widespread effects of ozone on crops and (semi‐)natural vegetation in Europe (1990–2006) in relation to AOT40‐ and flux‐based risk maps (2011, background): “…temperature increasing ozone production over and above that associated with global increases in precursor emissions, and the ameliorating effect of increasing carbon dioxide concentration on ozone effects (by reducing stomatal uptake), see reviews by Booker et al., (2009), Feng & Kobayashi (2009).”

Year 2030 potential crop production losses and economic damage under two scenarios of O3 pollution (2011, result): “Recent experimental- and observation-based studies support the results of model-derived estimates of regional and global crop losses (Feng and Kobayashi, 2009; Fishman et al., 2010).”
Stressed food – The impact of abiotic environmental stresses on crop quality (2011, background): “Abiotic stress factors such as drought, heat, soil salinity, tropospheric ozone and excess UV radiation are already causing significant agricultural yield losses and will become even more prevalent in the coming decades due to the effects of global change (Ashmore et al., 2006; Ortiz et al., 2008; B”
Quantifying the effects of ozone on plant reproductive growth and development (2012, background): “…reviewed more than a decade ago (Black et al., 2000), but recent quantitative assessments have focused on the influence of O3 on vegetative growth and development or crop yield (Morgan et al., 2003; Ainsworth, 2008; Feng et al., 2008; Feng & Kobayashi, 2009; Wittig et al., 2009; Feng et al., 2010).”
