AFAR TRIANGLE, ETHIOPIA (2/3/2013)

The concept of the Web arrived long ago in the nomad regions of Africa. Fast, reliable information is a survival tool—not a luxury—when it comes to locating scarce water holes or avoiding roving cattle raiders.

In the thorny plains of Ethiopia, the Afar herders have formalized a system of news-sharing called dagu. Anyone walking through the landscape can be stopped and pressed for information in a ritualized verbal exchange. Participation is required. Phrases such as, “how is it?” (wagari) and “it is clear” (sahali), are repeated in long cycles between more significant questions, until the participants squeeze each other dry of details. The word me’enahai signals the end of transmission. To outside ears, it can sound like two computers “talking” in binary code.

“It’s more accurate than our Internet,” said Kassa Negussie Getachew, an Ethiopian anthropologist who’s written a book on Afar culture. “You have to tell things exactly in a dagu. Whether a man has a scar on the left side of his forehead, for example. This will be passed precisely through many people. Even your walk will be part of the dagu exchanges all the way to Djibouti.”
