Oman: Roses of the Desert

The average temperature in summer in the desert state Oman of 40 degrees in the shade. It only cools down a little during wintertime.
Rain is a rarity, and natural rivers and lakes are non-existant. And yet people have made the desert flourish in many places - some fields even shine with the pink splendour of Field Rose blossoms.
All this is possible due to a 1,500-year-old canal system - the so-called "Aflaj" - an exceeding network of drains, floodgates and watercourses. Through the Aflaj, the water is directed to distant places kilometres away and brings life to the stone desert.
The "Wakil" is the person who is in charge of the Aflaj system's maintenance. The official job of a Wakil is passed on from father to son. Survival in the mountain villages of the Sultanate of Oman depends on these guardians of water. (official distributor synopsis)
