The Sahana Free and Open Source Disaster Management System is emergency management and disaster preparedness software developed by the Sahana Software Foundation. Conceived during the 2004 Sri Lanka tsunami to help manage the disaster, Sahana software was deployed by the Sri Lankan government's Center of National Operations (CNO), which included the Center of Humanitarian Agencies (CHA). Funding was provided by the Swedish International Development Agency (SIDA). The project has grown, with deployments during other disasters such as the Asian Quake in Pakistan (2005), the Southern Leyte mudslide disaster in Philippines (2006), the Jogjakarta earthquake in Indonesia (2006) and the 2010 Haiti earthquake.
