As Barcelona runs out of water, Spain has been forced to consider importing water from France by boat. It is the latest example of the growing struggle for water around the world – the "water wars".
Barcelona and the surrounding region are suffering the worst drought in decades. There are several possible solutions, including diverting a river, and desalinating water. But the city looks like it will ship water from the French port of Marseilles.
The water services authority in Marseille say that no contracts have been signed, and would not say how much the water would cost, although it is unlikely to cost any more than it costs the inhabitants of Marseilles. And the amounts of water than have been discussed are small – 25,000 cubic metres, less than what's needed to grow an acre of wheat, and not enough to keep 30 Spaniards going for a year, based on their average consumption.
