Vincent Ricciardi on Challenging Assumptions (rebroadcast)

Episode summary

In our discussion, data scientist Vincent "Vinny" Ricciardi challenges the assumptions and evidence that are built into food systems debates. We talk about a few of the recent papers that Vinny co-authored, including one that asks how much of the world’s food supply is produced by smallholder farmers, a 50-year meta-analysis that compares how do small and large farms size up in terms of yields and biodiversity impact, and whether smallholders actually have access to broadband to become part of a data driven farming future.

About Vincent Ricciardi

Vincent “Vinny” Ricciardi is a senior data scientist at Premise Data. Currently, he focuses on leveraging crowdsourced data from over 100 countries and 2.6 million contributors to inform public policy.

Equipped with a PhD in Resource Management & Environmental Studies from the University of British Columbia, Vinny has over 10 years of applied research experience. Since his start as a field scientist collecting biodiversity data, he has compiled and managed global-scale databases, led analyses for a wide range of stakeholders, and published in high-impact academic journals.
