The text messages are collected via a free-platform known as FrontlineSMS, developed by UK programmer Ken Banks.

The system was originally developed for conservationists to keep in touch with communities in national parks in South Africa and allows users to send messages to a central hub.

It has previously been used to monitor elections in Nigeria, and has now been combined with a “crowd-sourced, crisis-mapping” tool known as Ushahidi, which plots the reports on a freely-accessible map.

The system was developed in Kenya when violence erupted following the disputed presidential elections between Mwai Kibaki and Raila Odinga.
