Sahana is a Free and Open Source Disaster Management system. It is a web based collaboration tool that addresses the common coordination problems during a disaster from finding missing people, managing aid, managing volunteers, tracking camps effectively between Government groups, the civil society (NGOs) and the victims themselves.
The Sahana project was initiated by volunteers in the Sri Lankan FOSS development community to help their fellow countrymen and countrywomen affected during the 2004 Asian Tsunami in December 2004. The system was officially used by the Government of Sri Lanka and the system was released as Free and Open Source software. Subsequently a re-write as a generic disaster management tools was incubated with the sponsorship of SIDA, IBM and NSF (US) and it has be used by dozens of Governments and NGOs since then.
