The Danube we observe today is the result of the intertwined history of the riverine environment and the societies settling along the river. A large diversity of landscapes and ecosystems can be found. They are nowhere nature untouched by humans but rather a hybrid of natural and cultural characteristics. For example, biodiversity changed and will change even in those areas, which have been declared as natural heritage.
This lecture will give an overview on the long-term coupled development of environmental features of the Danube and humans, current environmental challenges and prerequisites for maintaining and improving natural heritage.
