Danube River Basin - Updated Transboundary Diagnostic Analysis (2006)
May 13, 2014 04:56 PM
This updated Transboundary Analysis (based largely on the findings of the 2005 Danube River
Analysis) identified four key concerns that are a priority for the Danube River Basin and the impact of
the Danube River on the Black Sea.
• Nutrient Pollution – potentially leading to over enrichment by nutrients and eutrophic
conditions. The main sources were identified as point emissions (both municipal wastewater
and industrial discharges) and diffuse sources, predominately from agriculture.
• Organic Pollution – potentially leading to low dissolved oxygen levels in the receiving water.
The main sources were identified as inadequate wastewater treatment from municipalities and
from diffuse sources.
• Hazardous substances – potentially leading to environmentally toxic conditions. The main
sources were identified as industrial (both active and from previous industrial sites) and
accidental pollution from shipping or mining activities.
• Hydromorphological Alterations – that have led to a loss of wetlands, impact on natural
aquatic conditions and present migration barriers for fish. Hydromorphological alterations are
the result of engineering works in rivers and lakes for navigation, hydropower generation, flood
The main focus of the GEF interventions in the Danube River Basin have been directed towards
nutrient pollution and its reduction. This is reflected in the level of information on this specific topic in
this updated Transboundary Diagnostic Analysis.
