Dry spell prompts water warning

Available for over a year

Water scarcity warnings have been issued by the Scottish Environment Protection Agency (SEPA) amid a lengthy hot and dry spell of weather. We ask freshwater scientist Dr Rhian Thomas from Glasgow University and the BBC's Kevin Keane why experts are concerned about a lack of rain. And Martin tells Laura the story of Millie, the fare-dodging dog. Scotcast is the BBC’s Scottish news podcast, with Martin Geissler, Laura Miller and Natalie Higgins.
