Prof Amos Tai delivered a talk on ‘Co-Benefits of Sustainable Food Production, Consumption and Trade to Mitigate Air Pollution, Climate Change and Food Insecurity’. The event was held at the CUHK and online via zoom with a total of 45 participants attended. In this talk, Prof Tai demonstrated how more sustainable farming methods may bring environmental benefits to help mitigate regional air pollution and climate change, while sustaining food security. He also introduced how rising food demands in different countries as well as a worldwide shift toward a meat-intensive diet have worsened air quality globally, and how international food trade could be responsible for “exporting” air pollution from one country to another.
