Hey @Margo there’s also this French initiative called SINGA (content in English), which is very popular here in France, and who aims at bringing connexions between refugees and locals by organizing joint activities, but also supports refugees willing to create businesses, organizations and cultural and artistic projects by connecting them with the relevant people and other organizations in the host country that can help them develop their ideas.
Recently, they’ve created a program / web application that aims at creating of network of citizens who are willing to open their homes and welcome refugees. They faced a huge success and a lot of people applied to welcome refugees in their homes, which was very positive, and they are now working on making this sustainable.
