Water is increasingly a scarce commodity – and it is at risk. Water is already being rationed in some areas of Germany.

Climate change with significantly increased average temperatures poses a threat worldwide and locally. An exhibition, lectures and station visits explain local and global references to the use of water in a changing perspective.
