Sustainability
5
River basins in Europe
6
European Centre for Ecological Water Quality and
Intercalibration (EEWAI)
  • to help Member States in harmonising and
    intercalibrating surface water ecological status
    assessment systems

Discussion Climate Change and Water Policy (2004)
  • What do we know about climate change scenarios
    for Europe and its various regions?
  • How is this likely to affect water resources,
    river flow and river basin management?
  • What are the impacts on biogeochemical cycles and
    contaminant cycling?
  • What are the impacts to ecological functioning,
    biodiversity, fish dynamics and stocks.

9
Synthesis document
  • Mandate to JRC (Steven Eisenreich) to coordinate
    the writing of a scientific synthesis document.

Common EU FP projects
  • (Climate and lake impacts in Europe)
  • Water bodies in Europe Integrative systems to
    assess ecological status and recovery
  • Adaptive strategies to mitigate the impacts of
    climate change on European freshwater ecosystems
  • Managing aquatic ecosystems and water resources
    under multiple stress
