Facts and Figures

Ships can navigate the Danube from 2,411 kilometres upstream all the way down to the Delta. This is 87% of the river's total length. The ships can call in at 78 harbours located along the Danube between Kelheim in Germany and the Black Sea in Romania.

The total length of the artificial dredged channels in the Danube Delta is roughly the same as the total length of natural watercourses (1,700 km).

Inland Navigation

Inland navigation can contribute to making transport more environmentally sustainable, particularly where it can act as a substitute for road transport. It can, however, also have significant influence on river ecosystems, jeopardizing the goals of the WFD.

Recognising this potential conflict, the ICPDR initiated in cooperation with the Danube Commission (on Navigation) and the International Commission for the Protection of the Sava River Basin a cross-sectoral discussion process involving all relevant stakeholders and NGOs. This led to the “Joint Statement on Guiding Principles for the Development of Inland Navigation and Environmental Protection in the Danube River Basin” , which was concluded in October 2007 and subsequently agreed by the Commissions involved.

The Joint Statement summarises principles and criteria for environmentally sustainable inland navigation on the Danube and its tributaries, including the maintenance of existing waterways and the development of future waterway infrastructure. These include inter alia the following:

  • Establishment of interdisciplinary planning teams, involving key stakeholders, experts from different organisations (governmental and non-governmental) and independent (international) experts to ensure a transparent planning process
  • Defining joint planning objectives and goals of IWT as well as river/floodplain ecology
  • Ensure flexible funding conditions, enabling integrated planning (including the involvement of all stakeholder groups) and adaptive implementation as well as monitoring
  • Monitor the effects of measures and – if relevant – adapt them

Within the framework of yearly meetings, exchange on the experiences with the application of the Joint Statement is shared amongst administrations, stakeholders and environmental groups.

Manuals & Plans for IWT

Furthermore, a “Manual on Good Practices in Sustainable Waterway Planning” was developed in the frame of the EU PLATINA project, which started in 2008 and concluded in early 2012. The manual further outlines practical steps for integrated planning approaches towards sustainable solutions taking into account both, the needs of inland navigation and the environment.

In 2014 a “Fairway Rehabilitation and Maintenance Master Plan for the Danube and its navigable tributaries” was elaborated in the frame of the EU Strategy for the Danube Region. The purpose of the Master Plan is to raise transparency in the area of fairway maintenance in terms of problems, activities undertaken and planned, and to highlight national needs and short term measures in the field of fairway rehabilitation. Further efforts and exchange for the application of the Joint Statement principles will be of particular importance during the practical implementation of the Master Plan.

Several new initiatives and actions involving different actors were launched since the year 2015 to support the process of making inland navigation and transport more environmentally sustainable.

What's Next?

A new initiative to support integrated planning of inland waterways transport was launched in the year 2017. Based on a proposal of the three Directorate Generals of the European Commission – Environment ( DG-ENV), Regional and Urban Policy (DG-REGIO) and Mobility and Transport (DG-MOVE) – a Mixed Environment Transport External Expert Team (METEET) on Integrated Planning of Inland Waterways Transport (IWT) Projects was set up. METEET is designated to assist competent inland waterways transport authorities on a voluntary basis with the objective to foster an integrated approach when developing infrastructural projects in the field of inland navigation.



  • » Joint Statement: Navigation & Environment
    In October 2007, a "Joint Statement on Inland Navigation and Environmental Sustainability in the Danube River Basin" was concluded and very positively received by stakeholders. In the years that followed, the responsible government authorities and interest groups met again to discuss the progress achieved so far and how to improve the application of the Joint Statement in waterway projects. These meetings continue.
  • » Dams & Structures
    Since the 16th century, people have been changing the natural course of the rivers in the Danube River Basin, mainly for flood defence, hydropower generation and navigation. All these changes affect the ecological quality of the rivers. Changes in the depth or width of a river typically reduce flow rates, interrupting natural sediment transportation as well as the migration routes of animals.
  • » Accidental Pollution
    Accidental pollution in the Danube River Basin can cause widespread damage to the environment, and endanger the health of local people and the state of local economies downstream. This was exemplified by the effects of the Baia Mare cyanide spill in Romania in 2000 or by the Hungarian redsludge accident at Aijka in 2010. The ICPDR is working to prevent accidental pollution and to improve response capability by compiling an inventory of all relevant "Accident Risk Spots".
  • » Invasive Alien Species
    The Danube River is seeing an influx of new non-native species, stemming from the increasing interconnections with various European and global water bodies via canals and other waterways designed to facilitate navigation. It is currently believed that alien species are very likely to become even more significant in the future, as the importance of the Danube as an international waterway increases.
