The Danube Transnational Programme (DTP) gathers one of the highest numbers of participating countries among all the Interreg programmes: 9 EU countries (Austria, Bulgaria, Croatia, Czech Republic, Germany - Baden-Württemberg and Bavaria-, Hungary, Romania, Slovakia, Slovenia) and 5 non-EU countries (Bosnia and Herzegovina, the Republic of Moldova, Montenegro, Serbia, Ukraine - four provinces: Chernivetska Oblast, Ivano-Frankiviska Oblast, Zakarpatska Oblast and Odessa Oblast).
Geographically, the DTP area overlaps with the territory addressed by the EU Strategy for the Danube Region (EUSDR), comprising also the Danube river basin and the mountainous areas (such as the Carpathians, the Balkans and part of the Alps). It is the most international river basin in the world. The area makes up one fifth of the EU’s territory and it is inhabited by approximately 114 million people. The variety of natural environment, the socio-economic differences and cultural diversity of the various parts of the area may be perceived as major challenges but actually represent important opportunities and unexploited potential.
