The Mesopotamian Marshes in southern Iraq, where the Tigris and Euphrates rivers merge, used to be one of the most fertile areas in the country. Today, they are fast disappearing. This is due to a series of issues including war, climate change and dam projects in Syria, Turkey and Iran. Bel Trew is the Middle East and North Africa correspondent for The Independent in the UK, and she recently visited the marshlands. She speaks with host Marco Werman about what she saw and how farmers are dealing with this water crisis.
