Ozone effects on crops: consideration for crop models

This research paper examines the mechanisms by which ozone causes injury to arable crops and discusses how these processes can be integrated into crop growth models to improve risk assessments for food supply under future climatic conditions.

• Ozone causes damage to crop plants through a process involving ozone transfer from the atmosphere to the leaf boundary layer and subsequent uptake via the stomata, which then triggers internal plant processes. These impacts occur across multiple scales, ranging from cellular metabolism and leaf-level physiology to whole canopy and root system processes, affecting photosynthesis, senescence, carbon assimilation, and the acquisition of water and nutrients, which ultimately impacts crop growth and yield.
• The authors advocate for the development of dynamic crop growth models—including empirical, radiation use efficiency, and photosynthesis-based models—that can incorporate ozone impact processes alongside other abiotic stresses. Such models would enhance national, regional, and global risk assessments regarding the role of ozone in limiting food supply under future climatic conditions.
• International collaboration through initiatives like the Agricultural Modelling and Improvement Intercomparison Project (AgMIP) is identified as a means for modellers to evaluate the capacity of various crop models to simulate the effects of ozone and other stresses.
