The ICPDR held a highly successful workshop titled "Sustainable Hydropower Development and Environmental Objectives – Framework, Challenges, and Ways Forward" on 4-5 June 2024 at the BOKU River Lab in Vienna.

The EU Water Framework Directive aims to make all waters cleaner and healthier. To meet these requirements, the ICPDR's Danube River Basin Management Plan closely examines the most important pressures affecting water status.
Significant water management issues, called SWMIs, are the central pressures of basin-wide importance affecting the ecological and chemical status of surface waters, including pollution by organic substances, nutrients, and hazardous substances, as well as hydromorphological alterations. The first interim overview on the Significant Water Management Issues was created in 2007 for the 1st DRBM. The SWMIs outlined in this report were derived based on the requirements of the WFD and mainly related to quality aspects. For transboundary groundwater bodies, both qualitative and quantitative issues are addressed.
