Ozone effects on crops: consideration for crop models

The paper reviews the mechanisms of ozone uptake and internal plant damage across scales from cellular metabolism to whole canopy processes. It argues for the development of dynamic crop growth models—including empirical, radiation use efficiency, and photosynthesis-based models—that can simulate ozone impacts alongside other abiotic stresses. The authors suggest that international collaborations like the Agricultural Modelling and Improvement Intercomparison Project (AgMIP) can help standardize and improve these simulations for better national, regional, and global risk assessments.

• Ozone causes crop injury through a process involving the transfer of ozone from the atmosphere to the leaf boundary layer and subsequent uptake via the stomata, which then triggers internal plant processes leading to damage.
• Ozone impacts occur across multiple scales, affecting cellular metabolism, leaf-level physiology, photosynthesis, senescence, and whole canopy resource acquisition of water and nutrients, ultimately reducing crop growth and yield.
• The development of robust crop growth models that incorporate ozone effects would significantly enhance the accuracy of national, regional, and global risk assessments regarding food supply limits under future climates.
