Danube Delta

The unique ecosystems of the Danube Delta consists of a labyrinthine network of river channels, shallow bays and hundreds of lakes. Interspersed with extensive marshes, reed-beds, islands and floodplains, it forms a valuable natural buffer zone, filtering out pollutants from the Danube River, helping to improve the status of the north-western Black Sea's vulnerable waters.

Ecological changes in the delta have reduced biodiversity, altered natural flow and sedimentation patterns, and diminished the ability of the delta to retain nutrients. Such changes include the creation of a network of canals through the delta for improved access and water circulation, plus a reduction in the wetland area from constructing agricultural polders and fishponds. Moreover, the most nutrient-rich waters now flow chiefly through the main canals, rather than being distributed through the wetlands and reed beds.

Did you know?

  • Most of the delta lies within Romania, but some of its northern fringes and most recently formed areas are in Ukraine.
  • A total area of 679,000 ha of the delta is under legal protection including floodplains and marine areas. The core of the reserve (312,400 ha) was designated as a “World Natural Heritage Site” in 1991.

    Moldova is one of the smaller countries of the Danube River Basin, but the Danube touches the southern point of Moldova for about 340 meters. Picturesque Moldova holds over 12,500km² of the Danube River Basin, including 8,300km² of the Prut River Sub-Basin, 3,300km² of the Yalpugh River Sub-Basin and 900km² of the Cahul River Sub-Basin.
  • » Romania
    The Danube is very significant to Romania, since the country is located almost entirely within the Danube River Basin. The Romanian section covers almost a third of the surface area of the Basin, and over a third of the river’s length flows through the country. Crucially, the Romanian (and also Ukrainian) Danube is the end carrier of all wastewater discharges into the Black Sea.
  • » Ukraine
    Three sub-basins of the Danube are partly located in Ukraine - the Tisza, Prut and Siret basins, as well as part of the Danube Delta. Furthermore, 2.7 million people live in the Ukrainian part of the Danube Basin, which is 3.3% of the total Danube Basin District. Ukraine has been a Signatory State to the Danube River Protection Convention since 1994. The Convention was ratified by the Ukrainian Parliament in 2002.

  • » Navigation
    Historically, the Danube and some of its tributaries have formed important trade routes across Europe. The harnessing of these rivers to facilitate navigation has radically changed their physical and ecological characteristics, while pollution from ships and boats is also a problem. In order to address this problem, the ICPDR is undertaking various activities.
