In October 2007, a "Joint Statement on Inland Navigation and Environmental Sustainability in the Danube River Basin" was concluded, followed by a series of annual meetings. Here, we present reports, minutes and background materials of these meetings.

The Danube navigation dialogue, concluded in October 2007 with the finalisation of the "Joint Statement", is continued. A first follow-up meeting was held in January 2009 in Budapest, a second one is held in March 2010 in Zagreb, serving to assessing the progress achieved so far and discussing how to improve the application of the "Joint Statement" in waterway projects.

Between April and October 2007, an integrated stakeholder dialogue was conducted by ICPDR, Danube Commissson and the International Sava Commission. Main activities were 3 workshops and the drafting of the Joint Statement document.

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.

daNUbs was a mulitnational EU research project carried out under the leadership of the Technical University of Vienna. The results from this project include estimates of nutrient inputs into the river network (MONERIS), as well as an assessment of the loads of nitrogen, phosphorus and silica transported via the river network. These results indicate that the nutrient status in the Black Sea has significantly improved since the 1980s.

The nutrient levels, notably phosphorus and nitrogen, found in the Danube River and its major tributaries hold significant international importance. This is because they directly contribute to the phenomenon of eutrophication in both the river itself and the Black Sea. Historical trend analysis of nutrient river loads over the past decades shows a significant reduction in the transported nutrient fluxes to the Black Sea. Overall nutrient emissions declined by 30% (nitrogen) and 50% (phosphorus) in the last 15 years. However, the current long-term fluxes are still considerably higher than those of the early 1960ies which represent river loads under low pressures, indicating a further load reduction potential that might be exploited for the benefit of the Black Sea. Nevertheless, in the last 5-10 years the measured loads are rather low and close to the Black Sea targets indicating significant water quality improvement.
