Ships bring water to parched Barcelona http :// news.bbc.co.uk/2/hi/science/nature/7398012.stm

Climb down the stony banks of the massive Sau reservoir in the
mountains above Barcelona and you get a real sense of why this famous
city is so short of water that it's resorted to bringing in emergency
supplies - by ship.
Nestling in a deep valley of stunning cliffs and forests, this vital
source of water has sunk so low it's exposed the eerie sight of a
medieval village that was flooded when the reservoir was opened in the
1960s.
The huddle of ancient stone buildings, including a church with its
spire, has now re-emerged into the light and stands as a potent symbol
of the severity of this water crisis.

The emergence of the village has brought sightseers to the reservoir
In a year that so far ranks as Spain's driest since records began 60
years ago, the reservoir is currently holding as little as 18% of its
capacity - at a time of year when winter rains would usually have
provided an essential boost by now.
Rainfall figures show a consistent series of shortfalls in recent
years - just as Barcelona's population has expanded to more than five
million and the region's booming agribusinesses demand ever more
irrigation.
For residents here, the arrival of water by ship is a profound shock -
normally it's the drier areas further South that are notoriously
parched.
Already they are living with restrictions on the use of hosepipes and
the filling of swimming pools.

Shipments of water are now needed to sustain the great city
Now the Barcelona authorities are having to take the unprecedented
step for any major European city of topping up supplies by the highly
visible means of giant tankers arriving in relays, each bringing 28
million litres, up to a dozen ships coming over the next month.
The shipments won't be enough to restore the reservoirs - or make the
ancient village vanish again.
But they may buy time for a highly controversial pipeline to be
completed by the end of the year. That should bring more reliable
supplies from a neighbouring region but at a high political cost.
And it may also remind people of the forecasts from climate scientists
of still drier conditions to come in the approaching decades.
