Rivers, lakes, transitional and coastal waters, as well as groundwater, are vital natural resources. A significant proportion of water resources are exposed to environmental pollution or other potentially damaging pressures. Protecting and improving the waters of the Danube River Basin is therefore essential for the natural environment, the sustainable development of the region and the long-term health, well-being, and prosperity of the population.

A recent large-scale modelling study has shown that restoring floodplains and reconnecting cut-off water bodies with the Danube River, and its tributaries could play a significant role in improving water quality and removing nitrate pollution in the Danube River Basin.
