Disaster Management System 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. Sahana currently has three projects: Eden, being developed in Python; Agasti, being developed in PHP; and the localization project, L10n. Community Resilience Mapping Tool In 2012, the Los Angeles County Department of Public Health (LACDPH) and Emergency Network Los Angeles, a voluntary agency, reached out to nongovernmental community organizations working in disaster and pandemic preparedness to find a better way of communicating with LA County's diverse population, to build resilience. Along with the RAND Corporation, the nonprofit policy think tank, the groups started a project called Los Angeles County Community Disaster Resilience (LACCDR), to educate and engage community leaders to promote resiliency in Los Angeles County. As part of the program, Sahana Software Foundation developed the Community Resilience Mapping Tool, to help communities collect data on vulnerabilities, hazards and resources within their own territories. The data allows communities to identify populations that could be affected by disasters, and plan the best way to allocate resources to help those people. Barriers like limited English proficiency, or low trust in public health, can be addressed through the tool. Google Summer of Code project From 2006 through 2014, Sahana has had a participating project in Google Summer of Code, a global program that offers student developers stipends to write code for various open-source software projects. Humanitarian-FOSS community Sahana has developed into a community founded by a humanitarian consultant, Paul Currion, and the Sahana project lead, Chamindra de Silva. Much of their work is based on the more generic ideals of "humanitarian-FOSS", where the ideals of FOSS are applied for building humanitarian-ICT applications or applications built to help alleviate human suffering. The community consists of a mailing list and an active wiki with membership including emergency management practitioners, humanitarian consultants, crisis management academics, and free and open-source developers from
