This paper was published 19 May 2022 and freely available (and a lot better looking!) on the open access journal website, Citizen Science Theory and Practice https://theoryandpractice.citizenscienceassociation.org/articles/10.5334/cstp.406/ The food system is comprised of biophysical and social processes affecting everyone, and food system citizen and community science offer opportunities for research, especially on unstudied aspects of that system, including responses to crises and disasters. We describe how community science work on food crop seeds responded to the crisis of the COVID-19 pandemic, and how this response built on the social investigations that are part of that ongoing work. To address a number of the crises of the Anthropocene, groups and individuals have been creating infrastructure supporting community-driven seed research and provision. Some organizations investigate community development of locally adapted crops, and introduction of novel materials for testing in new environments, as well as alternative social organization and processes supportive of this research and aligned with their values. Looking at examples of two active, United States–based, community seed organizations, represented by two of the co-authors, we outline the values and theoretical grounding of this work, and how responding to the acute crisis of the COVID-19 pandemic has challenged these organizations to rapidly develop seed distribution work in ways consistent with their values and missions. Meeting these immediate needs has meant temporarily pivoting from the longer-term evolutionary processes of their community science biological investigations; still, existing social investigations remained relevant and useful in their pandemic work. The effectiveness of this crisis response provides an example of explicitly values-driven research, and indicates the importance of recognizing the implicit social investigations of community science that sometimes experiment with alternative approaches to organizing society to achieve both immediate results, and longer term, prosocial change.
