Commentaries: Art. 15

The cantons shall reduce the risks from natural events to an acceptable level and limit such risks in the long term by compiling and evaluating the required basic data and planning and implementing measures in an integrated manner. In doing so, they shall in particular take account of the consequences of climate change and changes in the use of space.
Integrated planning must involve the relevant parties, combine measures in an optimal way and balance interests, in particular those relating to forest management, nature and landscape protection, hydraulic engineering, agriculture and spatial planning.
