Ushahidi is an open source project which allows users to crowdsource crisis information to be sent via mobile. It is is a free and open source project with developers hailing from Kenya, Ghana, South Africa, Malawi, Netherlands and the USA working on it.
Ushahidi, which means "testimony" in Swahili, is a website that was initially developed to map reports of violence in Kenya after the post-election fallout at the beginning of 2008. Ushahidi's roots are in the collaboration of Kenyan citizen journalists during a time of crisis. The website was used to map incidents of violence and peace efforts throughout the country based on reports submitted via the web and mobile phone. This initial deployment of Ushahidi had 45,000 users in Kenya, and was the catalyst for us realizing there was a need for a platform based on it, which could be use by others around the world.
