The history of water began more than four billion years ago. Humans have been part of the water cycle only for about two million years. To start with, we took water directly out of nature. When we organised ourselves in communities and moved into towns, we became dependent on water supply and sewerage. A sustainable society without pure water and healthy lakes is unthinkable.
What are the future challenges for water research? We have asked a number of people engaged in research relating to different parts of the water cycle in nature and society to put their personal visions on paper. Look on these visions as a contribution to the discussion regarding water issues and the role that research can play.
