Five heat waves with temperatures topping 40C this summer, together with a total lack of rain in recent months, have left water levels in the islands’ reservoirs dangerously low.
Experts say the driest winter and summer for 70 years has left water levels in Tenerife at less than 10 per cent of capacity with crops already failing.
The government has issued an assurance that supplies in urban areas are not affected.
Hardest hit are farmers who are subject to rationing in some areas with irrigation being applied directly without filling reservoirs to avoid loss through evaporation.
However, what is desperately needed is rain and lots of it.
