Africa’s Gift to Silicon Valley: How to Track a Crisis


Imagine if any Pakistani could send an anonymous text message to the authorities suggesting where to look. Each location could be plotted on a map. The dots would be scattered widely, perhaps, with promising leads indistinguishable from rubbish. But on a given day, a surge of dots might point to the same village, in what could not be coincidence. Troops could be ordered in.

This kind of everyone-as-informant mapping is shaking up the world, bringing the Wikipedia revolution to the work of humanitarians and soldiers who parachute into places with little good information. And an important force behind this upheaval is a small Kenyan-born organization called Ushahidi, which has become a hero of the Haitian and Chilean earthquakes and which may have something larger to tell us about the future of humanitarianism, innovation and the nature of what we label as truth.

After Kenya’s disputed election in 2007, violence erupted. A prominent Kenyan lawyer and blogger, Ory Okolloh, who was based in South Africa but had gone back to Kenya to vote and observe the election, received threats about her work and returned to South Africa. She posted online the idea of an Internet mapping tool to allow people anonymously to report violence and other misdeeds. Technology whizzes saw her post and built the Ushahidi Web platform over a long weekend.

The site collected user-generated cellphone reports of riots, stranded refugees, rapes and deaths and plotted them on a map, using the locations given by informants. It collected more testimony — which is what ushahidi means in Swahili — with greater rapidity than any reporter or election monitor.

When the Haitian earthquake struck, Ushahidi went again into action. An emergency texting number was advertised via radio. Ushahidi received thousands of messages reporting trapped victims. They were translated by a diffuse army of Haitian-Americans in the United States and plotted on a “crisis map.” From a situation room at the Fletcher School of Law and Diplomacy in Medford, outside Boston, Ushahidi volunteers instant-messaged with the United States Coast Guard in Haiti, telling them where to search. When the Chilean earthquake struck, Ushahidi deployed again.

A lot of things could go wrong with this model. People could lie, get the address wrong, exaggerate their situation. But as data collects, crisis maps can reveal underlying patterns of reality: How many miles inland did the hurricane kill? Are the rapes broadly dispersed or concentrated near military barracks?

Ushahidi remixes have been used in India to monitor elections; in Africa to report medicine shortages; in the Middle East to collect reports of wartime violence; and in Washington, D.C., where The Washington Post partnered to build a site to map road blockages and the location of available snowplows and blowers.
