"On 1 August 2013, heavy rains in the Sudan triggered flash floods that affected more than 530 000 citizens. The government failed to aid those affected and created a media blackout. More than 12 000 Sudanese volunteers created a horizontal network of citizens participating in a community-led initiative. The Nafeer campaign united the fragmented discourse, demonstrating that using ICTs to mobilise citizens is not contingent on the number of people with access, but on how access is channeled."
