The Fouguara (Irrigation System in the Sahara)

Hi everyone!
In this documentary you'll be introduced to FOUGUARA (a special irrigations system used in my city & nearby). It's unique system which dates back to centuries.
Many theories have been made about the origin of this marvelous and unique "piece of work" that man created, but it's hard to decide on it.
Unfortunately the fougurara is dying out because of lack of care and the use of alternatives like what we know today as tap water and other water supply systems.
Hope somebody would do something to preserve that heritage and keep it from disappearing...
(The Documentary is mainly in Arabic so I'll fetch some equivalent videos or do translation myself, which I hate most of all.)
Enjoy it
