Is Spain's Drought a Glimpse of Our Future?

Barcelona is a dry city. It is dry in a way that two days of showers can do nothing to alleviate. The Catalan capital's weather can change from one day to the next, but its climate, like that of the whole Mediterranean region, is inexorably warming up and drying out. And in the process this most modern of cities is living through a crisis that offers a disturbing glimpse of metropolitan futures everywhere.

Its fountains and beach showers are dry, its ornamental lakes and private swimming pools drained and hosepipes banned. Children are now being taught how to save water as part of their school day. This iconic, avant-garde city is in the grip of the worst drought since records began and is bringing the climate crisis that has blighted cities in Australia and throughout the Third World to Europe. A resource that most Europeans have grown up taking for granted now dominates conversation. Nearly half of Catalans say water is the region's main problem, more worrying than terrorism, economic slowdown or even the populists' favourite -- immigration.

The political battles now breaking out here could be a foretaste of the water wars that scientists and policymakers have warned us will be commonplace in the coming decades. The emergency water-saving measures Barcelona adopted after winter rains failed for a second year running have not been enough. The city has had to set up a "water bridge" and is shipping in water for the first time in the history of this great maritime city.

A tanker from Marseilles with 36 million litres of drinking water unloaded its first cargo this week, one of a mini-fleet contracted to bring water from the Rhone every few days for at least the next three months. So humbled was Barcelona when prolonged drought forced it to ship in domestic water from Tarragona, 50 miles south along the Catalan coast, 12 days ago, that city hall almost delayed shipment and considered an upbeat publicity campaign to lift morale and international prestige.

The whole country is suffering from its worst drought in 40 years and the shipments from Tarragona prompted an outcry from regions who insist they need it more. For now the clashes are being soothed by intervention from Madrid, and plans to ship water from desalination plants in parched Almeria in Andalusia are shelved until October. But there is little indication of a strategy to deal not just with an immediate emergency but an ongoing crisis. Buying water on an epic scale from France has given the controversy an international aspect as French environmentalists question whether such a scarce natural resource should be sold as a commodity to another country.

"It would be a mistake to consider this water bridge between Marseilles and Catalonia as simply an operation of solidarity," said a group of ecologists calling themselves Robin des Bois (Robin Hood). They said the commercial deal struck between private contractors failed to consider the environmental impact on France. The organisation blamed Barcelona's water shortage on "wasted resources and ... lack of foresight by Catalan and Spanish authorities".

What Barcelona authorities are fast discovering is that chronic water shortages are not a problem that money alone can solve.

Its 5.5 million inhabitants need a lot of the stuff: the 20 million litres/20,000 tonnes/five million gallons of water brought from Tarragona on 13 May were enough for barely 180,000 people and were consumed within minutes of being channelled through the city's taps. Wednesday's shipment from Marseilles was bigger, 36 million litres, but similarly short lived.

Barcelona has churned up a whirlpool of controversy over its handling of the water crisis, causing just the spray of negative publicity it hoped to avoid.

Even the arrival of rain has only made things worse. Catalonia's regional environment minister, Francesc Baltasar, rushed to announce last week that the hosepipe ban and swimming pool restrictions imposed in February would be lifted. Tarragona -- whose wells supply shipped-in water -- protested furiously. "Barcelona fills its swimming pools with water from Tarragona," local headlines screamed, and the water authority demanded a halt to pumping Tarragona's water for the Catalan capital.
