This paper explores Brent Edwards's 2001 notion of "décalage" and its role in the evolution of the African diaspora studies. I argue that this notion should be profoundly considered in envisioning the future of the field since it not only reflects the original chasm between African and African-American understandings of the diaspora as Edwards states, but it also illustrates how the diaspora has gradually turned into multiple and sometimes scattered diasporas. I also contend that this multiplicity forces us to question what unites African and Afro-descendants today. I do so relying on Gilles Deleuze's disjunctive synthesis to examine these three dimensions of diasporan relations. I also discuss how ideological frameworks such as Pan-Africanism or Négritude bridged differences thanks to key ideas of emancipation, black existence and connected struggles. I finally explore contemporary models that could renew diaspora studies: Africana and Afro-liminalities.
