In a week of headlines about water shortages slowing ships in the Panama Canal and drought in India's Silicone Valley, we look at unexpected ways to manage the world’s water.
Presenter Marnie Chesterton and panellists Chhavi Sachdev in Mumbai India and Meral Sachdev in Nunavut Canada tell stories of innovative ideas being tried in their parts of the world.
Then Marnie meets water detective Barbara Sherwood Lollar - Professor in Earth Sciences at the University of Toronto - to hear how ancient water can help us plan for the future. Plus, how submersible speakers can help corals and stories of living underground.
Produced by Dan Welsh with Tom Bonnett, Harrison Lewis, Jack Lee, Katie Tompsett and Emily Preston
