19 countries share the Danube River Basin, which makes it the world’s most international river basin.

More than 81 million people of different cultures and languages call the Danube Basin their home and are since centuries interconnected through the widely ramified water system of the Danube. All countries sharing over 2,000 km² of the Danube River Basin and the European Union are contracting parties of the ICPDR.
