A television documentary about the reviving of ancient water tunnels in Syria. Dutch film-maker Joshka Wessels spent two years making Tunnel Vision. Wessels has recorded the revival in Syria of a system of underground irrigation that started to fall into disuse at the time of the Roman occupation. The 'qanats' are a membrane of tunnels starting again to supply water to farmers in this arid country. In the Gulf it's called the 'fallaj'. It is believed the Persians invented the system almost three thousand years ago. A case of back to the future?
