“…4). The greater sensitivity of wheat and rice to O 3 in the Yangtze Delta where wheat and rice grow without water and nutrient stresses than that predicted from North American doseeresponse relationships has been reported by Emberson et al (2009). Compared with our study, the wheat and rice used in North China by Feng et al (2003) were less sensitive to O 3 (Fig.…”

“…It is difficult to assess the differences in the response of wheat and rice to AOT40 between the constant and diurnal pattern of O 3 exposures because of yearly variations in exposure duration and dose in this study. Emberson et al (2009) have reported that there were no obvious differences between the sensitivities of Asian winter and spring wheat varieties planted in different countries. Analysis of variance and generalized linear modeling (GLIM) showed that there were no statistically significant differences between the slope of the regressions for the data from the USA and EU for each of the crops studied (Mills et al, 2007).…”

a b s t r a c tThe effects of a continuing rise of ambient ozone on crop yield will seriously threaten food security in China. In the Yangtze River Delta, a rapidly developing and seriously air polluted region in China, innovative open-top chambers have been established to fumigate winter wheat and rice in situ with elevated O 3 . Five years of study have shown that the yields of wheat and rice decreased with increasing O 3 concentration. There were significant relationships between the relative yield and AOT40 (accumulated hourly O 3 concentration over 40 ppb) for both winter wheat and rice. Winter wheat was more sensitive to O 3 than rice. O 3 -induced yield declines were attributed primarily to 1000-grain weight and harvest index for winter wheat, and attributed primarily to grain number per panicle and harvest index for rice. Control of ambient O 3 pollution and breeding of O 3 tolerant crops are urgent to guarantee food security in China.

“…On the ozone side, chamber, open-top, and other field experiments have resulted in hundreds of dose-response relationships for individual crop cultivars over a range of agro-ecological zones and ozone concentrations (15)(16)(17)(18). These dose-response relationships have been used to estimate global and regional crop loss in individual years, as well as into the future under different emissions scenarios (11,(19)(20)(21)(22)(23)(24).…”

Recent research on the agricultural impacts of climate change has primarily focused on the roles of temperature and precipitation. These studies show that India has already been negatively affected by recent climate trends. However, anthropogenic climate changes are a result of both global emissions of long-lived greenhouse gases (LLGHGs) and other short-lived climate pollutants (SLCPs). Two potent SLCPs, tropospheric ozone and black carbon, have direct effects on crop yields beyond their indirect effects through climate; emissions of black carbon and ozone precursors have risen dramatically in India over the past three decades. Here, to our knowledge for the first time, we present results of the combined effects of climate change and the direct effects of SLCPs on wheat and rice yields in India from 1980 to 2010. Our statistical model suggests that, averaged over India, yields in 2010 were up to 36% lower for wheat than they otherwise would have been, absent climate and pollutant emissions trends, with some densely populated states experiencing 50% relative yield losses. [Our point estimates for rice (−20%) are similarly large, but not statistically significant.] Upper-bound estimates suggest that an overwhelming fraction (90%) of these losses is due to the direct effects of SLCPs. Gains from addressing regional air pollution could thus counter expected future yield losses resulting from direct climate change effects of LLGHGs.climate impacts | ozone | aerosols | agriculture | India

“…Further, Debaje et al (2010) estimated that the winter wheat and summer crops yield losses by 10 % and 15 %, respectively using AOT40 index from present measured O 3 pollution level in the rural India. Emberson et al (2009) reported that crops respond differently to O 3 exposure in Asia (India in particular) than in USA and Europe underestimating crop yield losses occur at the present O 3 concentration. A recent synthesis of experimental data from Asia shows that today's concentrations (40-80 ppb) of O 3 cause yield losses of three staple Asian crops (wheat, rice and legumes) that vary between 5 % and 48 %, 3-47 % and 10-65 % respectively.…”
