Water in the hungry, poor, and urbanizing world – a focus on uncertainty and interdisciplinarity

There has been a boom of global assessments and summit meetings – tarketing on global key natural recources, population and oyher issues, and on economic questions- in the few years. They have set a new basis for our knowledge on the evolution of the globe’s state. Howerver, there is space for many developments and improvements. We discuss the crucial roles of uncertainty and interdisciplinarity, which are by now understated. Water is deeply interconnected with issues such as food production, poverty, and urbanization, and without such interconnections, analyses cannot provide all the needed and potential support to policy makers. The crucial role of these issues should be fully appreciated in water resources assessments, and water should be fully recognized in assessments concerning them.
