The tech that could make water use sustainable
Scientists in Finland and the UK have built a computer model that visualises what water is doing underground in real time.

Niko Putkinen, a senior scientist at the Geological Survey of Finland, and Holger Kessler, from the British Geological Survey, explain how the system works.
