After the Shock, the Corridor Cities Do the Arithmetic of Thirst Again

KARACHI — An exchange in a glass tower logged a number on Wednesday morning, and by Wednesday evening it was standing in Rashida Bhatti's doorway. The corridor cities have learned, over three hard years, how fast a market abstraction becomes a kitchen decision — how the distance between a print and a pot of water is measured in hours, not weeks. Utilities that buy their input on the exchange began signaling pass-throughs before the session closed, and the standpipe queues, which had shortened all autumn, lengthened again by nightfall as families topped up ahead of the notices they knew were coming. "The rich hedge, the poor hoard, and everyone in between reads the meter twice," said hydrologist Farida Qadeer. On the corridor the shock has no ticker symbol; it has a jug, a queue, a notebook, a mother's pencil. The households did the arithmetic of thirst in the dry years and swore they were done with it. Wednesday handed them the pencil again. They did not need to be taught how to hold it.
