This guide is designed to serve government actors, both national and local, involved in any process of Sustainable Development Goal implementation, including those working specifically in migration, and those working in other sectors who are interested in integrating migration. It is also for government actors working in the migration field who wish to integrate the SDGs into their work. For actors with experience in migration mainstreaming, this guide offers a new approach that is based on the 2030 Agenda. For those with no experience in migration mainstreaming, it offers an introduction on how migration and development are linked in the context of the SDGs, and how to take action around these connections.
