With the rising population, urbanization and industrialization, tropospheric ozone (O₃) pollution has become a serious challenge to India's food security. We have reviewed the O₃ exposure-based Indian studies on yield and quality losses in important crops under the current and future concentrations of O₃ to identify the current challenges and policy interventions to reduce the risk of O₃ threat to food security in India. The order of sensitivity in major crops is wheat ˃ mustard > rice > maize under ambient O₃ concentration. However, the sensitivity of crops at elevated O₃ (10–30 ppb) varied with exposure dose, stomatal flux, intrinsic defense response, etc. Effective implementation of the reduction in emission of O₃ precursor gases and growing O₃ tolerant crops might be helpful to mitigate the O₃ impacts at local and national levels.
