This report brings together best practices of diasporas responding to the COVID-19 crisis in the African, American, Asian, and European regions. iDiaspora was able to collect this information during three organized Global Diaspora Virtual Exchanges. It created a collaborative space where diaspora groups from around the world could share their best practices responding to the pandemic. Through these events, diasporas were able to showcase their work and enhance synergies with policymakers, practitioners and stakeholders involved the COVID-19 response. These initiatives demonstrate the capacity of diasporas to develop transnational interventions and their ability to respond to emergencies, in particular, with the use of digital platforms and technology.
