War for water in Chile's Atacama Desert

Chile's Copiapo Valley should be a picturesque grape-growing region. Instead, there is mile after mile of rows of withered vines along this stretch of the Atacama Desert.

Not so long ago these vineyards in northern Chile were green, supplied with water from an underground reservoir.

But water is a rarity here, in the driest desert of the world. Not least because agriculture is not the only industry competing for it.

Chile is known for its copper exports, but mining companies also need water - so they buy water rights from local farmers.

The BBC's Katia Moskvitch has the story.
