Agricultural production is at risk due to the double threats posed by climate change and air pollution. Deposition of ozone causes substantial crop yield losses in many parts of the world with certain estimates putting the global loss in wheat yields at between 6% and 9% on average in the southern and northern hemispheres, respectively. The international community is developing approaches to provide globally consistent maps of ozone deposition as a tool for evaluating the risks to agriculture. The concept of measurement-model fusion will be presented at the event and put in the context of the UN’s Sustainable Development Goals. The session will reflect on the complex interactions between atmospheric composition and agriculture and present examples of the agricultural practices that can serve to reduce crop losses due to ozone deposition in India.
