The Nile is Egypt and Egypt, for many, is the Nile. For over 8,000 years, this historic River has nurtured civilization. But now, Cairo says that’s under threat. Hundreds of kilometres upstream, Ethiopia has built a mega dam. It stands over 155 metres tall and nearly 1800 meters long.    Host James Haines-Young talks to Hamza Hendawi, The National’s Cairo correspondent, and William Davison, a senior analyst based in Ethiopia for Crisis Group. We also speak to Hafsa Halawa, a non resident scholar at the Middle East Institute about the Grand Ethiopian Renaissance Dam.
