The Global Ecumenical Network on Migration (GEM) enables members drawn from churches, church-related organizations and ecumenical bodies working on migration to learn from each others' experiences, develop a global analysis, set priorities together and pool their resources to advocate on these issues at the United Nations and with other organizations addressing migration. The aim is to deepen understanding of global migration issues and have more impact on global policy discussions on migration. 

In comparison to its predecessor, the Global Ecumenical Network on Uprooted People (GEN), the new network works more specifically on migration issues, particularly the relationship between migration, racism and xenophobia, and the effect of migration on changing ecclesial contexts.
