Comparative evidence from five international Agriculture, Nutrition and Health Academy Week conferences date: 2022-02-09 journal: Lancet Planet Health DOI: 10.1016/s2542-5196(21)00355-7 sha: c42d9cd9d49c760537f0feb9bbc2a8ba33d605e7 doc_id: 27278 cord_uid: a0yyhnh7 The advancement of science and evidence-based solutions for planetary health increasingly require interdisciplinary and international learning and sharing. Yet aviation travel to academic conferences is carbon-intensive and expensive, thus perpetuating planetary health and equity challenges. Using data from five annual international Agriculture, Nutrition and Health Academy Week conferences from 2016 to 2020, we explore whether moving to virtual conferencing produced co-benefits for climate, participation, attendee interaction, and satisfaction. We report on: absolute number of attendees, proportion of attendees from countries of different income levels, number of participants at social events, aviation CO(2) emissions, and overall ratings of the event by participants. Transitioning online resulted in large reductions in travel-related aviation CO(2) emissions, alongside increased attendance—including among attendees from low-income and middle-income countries. This was achieved without a major change in the participant rating of the event. However, the online format resulted in lower participation in conference social events. The urgency of reducing CO(2) emissions in pursuit of planetary health and improving equity in scientific exchange requires new modalities of academic conferencing. This study indicates that co-benefits can be achieved when transitioning online. Challenges exist for virtual events, such as emulating the intangible facets of in-person interactions, overcoming time-zone limitations, and digital divides. Note: 1 Nepal's classification was raised from lower income to lower middle income in fiscal year (FY) 2021. The classification was unchanged across years for all other host countries. 2 The specific rating questions are in Section B of the online supplemental materials. For years 2017-2021, the ratings came from a single overall participant survey question. For year 2016, the survey lacked an overall rating question, so the rating is a participation-weighted average of ratings from session-specific ratings. B.
