The health and vitality of any community relies on the health and vitality of the people who are there. The goal of this session is to promote efforts in the Earth and space science community fostering a supportive scientific space for people from all backgrounds. We encourage submissions from researchers and practitioners who are broadening participation and increasing retention by exploring the ways to optimize support of historically excluded groups. Submissions can include literature-supported programming and results, case studies, and theories and methodologies. Themes can include but are not limited to institutional accountability, student success and the learning environment, grassroots community initiatives,  increasing employment opportunity, and interpersonal behaviors and competencies. This session is organized by the Student and Early Career and DEIA working groups of the AGU Education Section and AGQ, the AGU LGBTQIA Affinity Community.
