Attempt to save Iraq's marshes from the desert
The Mesopotamian Marshes in southern Iraq were once home to thousands of marsh Arabs, millions of birds - and rebels fighting against Saddam Hussein.
In the 1990s he ordered his engineers to drain the land as a punishment, turning the land to dust.
Now conservationist and environmental engineer Dr Azzam Alwash is attempting to restore the marshes.
The project is the subject of the first in a new series of Natural World.
He and cameraman Steve Foote spoke about both the difficulty of the restoration and the issues filming in what is still a dangerous country.
Miracle in the Marshes of Iraq will broadcast on BBC Two on Tuesday, January 18th at 2000GMT.
