Human migration is a matter of global concern. Flows of migrants and refugees influence and change the social, economic and political dynamics of their destinations -- and the places they have left behind. IPS covers crucial issues such as migrant and refugee rights, irregular or undocumented migration, human trafficking, remittances, displaced persons and forced labour. And the positive: in many cases migration creates a new dialogue among civilisations. Migrants themselves become the building blocks of bridges connecting different cultures.
