Producer: Louise Potterton, Video Editor: Petr Pavlicek

The key to good water management is knowledge - knowing how much water is there, where it comes from, where it flows and finding out its age and quality. Such information can be gained through the use of isotope hydrology. Pradeep Aggarwal, Head of the IAEA Water Resources Programme and the Isotope Hydrology Laboratory, explains how this form of hydrology works and how it aids sustainable development.
