For Organisations Considering Sahana

Sahana is a web-based disaster management application that provides management solutions, focusing on large-scale humanitarian disasters. It enables enhanced coordination by promoting integrated information gathering. It assists collaboration by providing a number of communication mechanisms in the aftermath of a disasters. Sahana is built from free and open source software and released under the GNU Lesser General Public Licence, which means all users are free to download and use it (and are even free to create commercial derivatives of it)...

How Sahana is useful in disaster situations

Sahana functions both online as well as a stand alone tool for disaster management, depending on the operational considerations. Users can access it via their local machine, from within the network, as part of a corporate intranet or anywhere in world via the Internet. This means it can be installed on a laptop, for workers in the field and at a central command center for overall coordination. When machines are linked, all information can be synchronised, via USB, CD-R the LAN or the Internet...

Supported Operating Systems and Web Browsers

Sahana supports all modern operating systems and browsers, including MS Windows, Mac OSX, Ubuntu and other Unix-like systems. Your browser must have JavaScript enabled, and your operating system must be able to run the Apache HTTP Server, the PHP programming language and MySQL database software. If you don't know what these are, the Installation Guides below will assist you.

Case Studies

Sahana's strength is also in its track record being deployed for disasters around the world. Known deployments of Sahana have been for the governments of Pakistan, Philippines, Peru, US and Bangladesh. The following are some of the case studies of Sahana deployment, where we can see how a community of partners worked to deliver the Sahana solution at a time of need
