Examining the foundations of why DEIJ matters in geography, this book engages readers in historical and empirical facts and a number of epistemic interventions from Black, Latinx, Indigenous and Asian-American geographies, as well as Women of Colour, queer, trans, and disabled geographers. It also provides theory-informed, yet hands-on guidance on how to foster DEIJ across academia, through geography unit leadership, school geography, graduate students, undergraduate teaching, and mentorship for safe and inclusive fieldwork.
