I thought Arequipa's blueouts were bad, but this piece revealed some disturbing facts about Peru's capital:
1) Lima is the second largest city, after Cairo, located in a desert.
2) Two million of Lima's eight million people don't have access to running water.
They've got some ideas to solve this water shortage, including a joint dam project (see The Economist) between Cuzco and Puno in the Peruvian jungle.
There's just one problem. The dam's reservoir would flood 120 kms of a new interstate highway between Brazil and Peru that's already under construction. A little interagency miscommunication makes for a big water problem.
P.S. It's still hasn't rained. That brings the count to 123 days without a drop.
