A crumpled note, delivered to a passing rock star-turned-philanthropist? No, Mr Sokor is a much sharper communicator than that. He texted this appeal from his own mobile phone to the mobiles of two United Nations officials, in London and
Nairobi. He got the numbers by surfing at an internet cafe at the North Kenyan camp. 

As Mr Sokor’s bemused
London recipient points out, two worlds were colliding. The age-old scourge of famine in the Horn of Africa had found a 21st-century response; and a familiar flow of authority, from rich donor to grateful recipient, had been reversed. It was also a  sign that technology need not create a “digital divide”: it can work  wonders in some of the world’s remotest, most wretched places. 

“Technology completely alters the way humanitarian work is done,” says Caroline Hurford of the World Food Programme (WFP), a United Nations body that is the single largest distributor of food aid. Once upon a time, when disaster struck, big agencies would roll up with grain, blankets and medicine and start handing them out. Victims would struggle to the relief camps, if they could. For aid workers (let alone recipients) there was no easy way to talk to head office. 

Now, when an emergency occurs, the first people on the ground are often computer geeks, setting up telephone networks so other aid agencies can do their stuff. Donors keep track of supplies on spreadsheets and send each other SMS messages: this road has been attacked by bandits, that village cut off by floods. Transport agencies announce helicopter flights by e-mail. Aid providers can find out where exactly on an incoming ship their medical supplies are, saving hours hanging round the docks. Aid donors find it easier to locate the victims of disaster; and victims queue as eagerly for mobile-phone access as they do for food.
