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 system can be deployed on a variety of models, ranging from operating totally within a single notebook computer (with or without a portable Wireless LAN) to a fully distributed, networked platform.
• Can efficiently scale down to a standalone laptop and a secured portable wireless access point for short-range network collaboration
• Access can be provided in the affected region with the support of groups who provide satellite-based wireless LAN connectivity to networks
• Works with the equipment at about 130W, which can be easily supported by a solar panel if power is not available
• It can also synchronize data between multiple instances of Sahana.
