The water timeline visualizes the dynamic history of Swiss water management over the last 200 years by presenting roughly 200 milestones based on images, text and sound. The project aims to demonstrate how technological, social and ecological changes interact in transformations towards sustainable development, and under what conditions paradigm shifts in our use of natural resources become possible. The project team hopes to spark the interest of a broad audience, and to make the timeline a key input to broader dialogues on sustainable development in the water sector and related contexts. The water timeline will be continuously updated and improved. We look forward to receiving your comments and suggestions!
