This is the 17th Human Welfare Conference, which has been organised annually by graduate students at Green Templeton College since 2008. This year, we explore food sustainability across multiple levels—personal, local, and global—while fostering interdisciplinary and transdisciplinary interactions among students, grassroots organisations, and senior researchers. Our keynote speakers will each deliver lectures on food systems and sustainability, focusing on global and national approaches. Graduate students will deliver talks about their research and there will be a Friendly Food Fair with the college kitchen, community-based organisations, and local social enterprises.
